Hey May!

Hai hai hai.... A quick update to welcome may. Recently i met someone new. Well, we started to talk regularly now. But not too deep. We discussed about our problems, not my turn yet though. But we start talking. I tried my best to not make any stupid move. I would like to make our meeting as a friend. I hope nothing more. Just to go day by day like that. Clean. Because there are too many times that friendship died out because i advanced too fast. So it is like that now. I try my best to suppress things. Hope this time will work out. Well our age difference is not that far, around 5-6 years. I don't want to lose friends again.

That's that. let's move on. Last Sunday, i went out to the beach but i didn't spend that much time staring at the sea. Almost all of my time, i spent it in my room. I watched the sea, but it didn't attract me much this time. Because my mind was still wandering. The pressure to finish my college keep on haunting me. If i want to clear all things, the first step i have to do is finishing my college life. So i can move on to the second part of life. Maybe i am such a coward. Enjoying so much for small paid jobs. A million for a month is so small, yet i already felt satisfied. I am such a hypocrite. I could have been someone so great, yet i chose to dilly-dally. I have so many masks to disguise yet i choose the truth mask almost all the time. What a waste.

Alright for the last part is me becoming so much better in driving. Well, i am someone who love speeding. Used to do unofficial street racing all the time. Sometimes i won, sometimes i learned. I beat so many vehicle that should be faster, yet because the driver was me, i won. Looks like i am bragging. lol. The adrenaline is still there. I could feel it in my last trip. Right now, i have to focus all of my energies to clear all the things that have to be done soon. Anyway, thanks for reading. See you soon.

Hello April

Yo people. It has been a while since I've written anything new. I don't think i am back yet to write more. I have the will, yet problems stopped me from writing. There were so many new experiences that happened recently.

So the google+ have ended its service. Before you could continue to login to your blog, you have to fill a new name, so the blogger site can address you. Before, they just copied my full name from google+ and now they told you to write it by yourself. I think this is good, because my full name is kinda long. So "posting as (nickname)" looks so much better.

Alright as i make this post about hello, i will not tell much. Just some flash news or any kind of new information. It has been 4 months. Nothing significant that could benefit me much. In the past few months, i have been trying to finish all the things that have left behind. Things just got well in past few days, i meant i have found some people that could help me. We were making appointment here and there. So i hope things will workout smoothly before my sixth brother come back from his study to spend holiday with us. Things about growing, he is the fastest among us 7. The sixth changed almost completely as a different person. I don't know it will be good thing or bad thing, but he is definitely changing. I would like to see him by myself later. He is young so "people don't change" still won't happen yet on him. He is shaping, but us as adult already took a shape. So i still believe "people don't change" apply only for us, adult.

About that quote, i felt it myself and from some close people's experience that i knew. People really don't change. They are still the same. It might be impossible to change the form. Of course there are possibilities that i am at the wrong here. We are humans. It is not easy to change our habit. From the paper science that i read, to make something as a habit, humans need around 66 days, yet you believe that things that already take form could change over a single night or single month? i don't. It's plainly impossible. Give me your example in 5-10 years. I might believe you could change.

I am so done for trusting people too easily. Because it happened again and again in my life. I felt like they were toying with me. I am not that stupid to point things out. I am just lazy. Anyway that's it. Maybe write things randomly like this might be much better than waiting for me to revise my drafts.

Oh, i am considering to buy a new graphic card and new power supply as i intend to use my computer more. I hope from buying those, i can become more productive. Alright, see you later folks. Hemmmm.... another thing, i might write some Bahasa Indonesia language in the future as i want to backup some of knowledge from my college life in the past. Adios....

The Calm Mode (Part 2)

Haiii heyyyy oiiiii.... 3 times because i was absent for so long. There were so many events that happened to me for the last 3 months. Most of them are sad story though. I will write about it later. I hope i will not forget about it, so i can share it with you guys. Alright, let's keep it short and focus on continuation from the last part. 

The calm mode have advantages and of course disadvantages. I can't mention it all, but i can address some that i experience and happen most of the times. For me, they are in gray area. Because sometimes, it was the right thing, other times it was not. That is why i called it gray.

First of all the example is like when i really needed to get angry, it did not happen and made me look stupid instead. At the moment when my emotions boiled up for some seconds, it died down as soon as it wanted to explode. It was so bad. When i was supposed to be angry, i laughed instead because the emotions were gone. It left me at the neck of climax without reaching the peak. It happened to the happy, the fear and the sadness too. But there are some occasions that the calm mode do not happen in instants. It was the condition in extreme mode. When i lost the ability to think and left it all to my heart. The only thing that could reach the extreme mode currently for me was the sadness. I have not experienced for the other emotions because the sadness was the only thing that happened to the extreme when i was learning about managing emotions. So of course, the wall would collapse so easily whenever facing the extreme wave of sadness.

Anyway, that is all. I knew this was meaningless, but i just wanted to tell you all and shared it. I should have post it few days after the first part, but things became quite hectic at those days behind. Sigh.... I am disappointed to myself. I let myself drown in laziness. There are so many project unfinished that i need to take care. Yet here i am.... writing. Errr.... thank you for reading this. Because as i am writing this, i do not have the zeal to tell a story and this thing is not that interesting. It should have been merged with the first part. My bad. Alright, see you on another post.

The Calm Mode (Part 1)

Alright folks, as I said in my previous post, I would like to talk about emotion. I will split the stories into few parts and make sure it is not a long post. If it is too long, it will be boring to read. Of course, I know that by writing this, many people will find it boring already. Because this blog is about me and my journey. Alright enough about that, let's get to it.

This happened way back at 2013, at that time, i was slowly recuperating from broken heart because i lost someone dear to me. I was in denial state. I kept on forcing myself on her. This was my biggest mistake, because i already knew that there was no hope anymore. But i still convinced myself to chase after her. This led me to "books". The surface only though and relationship related thingy. I tried so hard to find some piece of hope to reunite with my love. I couldn't sleep properly. I ate like a madmen. I became depressed. That was why i really couldn't picture what I've done at that time from other people's perspective. For me, i have to find a way to be together again.

It went day by day until i stumbled upon these words. The famous newton 3rd Law. This thing transformed me completely. At that times, i healed myself by going to the beach or just watched anime. From anime, I met the all-time masterpiece, Fullmetal Alchemist. This anime was one of the reason i opened my eyes. To understand the human nature. The most life changing moment was started by this anime. It completely reformed my mind about so many things. Then my mind was craving for knowledge, and then it forced me to keep on reading while distracted me from negative thinking. After that, i spent most of my time by reading whatever i could find to complete that fragile mind and to make sure that i was walking in the correct path by assessing everything with logic. Beside reading, i joined a community for Japanese related thingy in my city to increase my interactions.

After some period of time, the wall finally became solid, my eyes began to see much more. Things that I've been neglecting finally came to me. At that time, regret was the biggest word for me. The first thing i did was to get closer to my family member. I mean dad. mom and my 6 siblings. Interacting more with them. Loving them much more than before. Value them more. I found the true love that could love me back as much as i gave. It felt so incredible and powerful.

Mom gave me the warmest hug i could get. She always understands me. She told me what she have been seeing in recent years. How it made her heart broken to see me in a bad shape. How it made me became unstable. I really hold my best to not cry in front of her. But of course i shed manly tears after realizing every thing that i could remember.

All the things that happened. I spent almost a full month to remember every single thing that happened to me. I went around to many people's house to settle things. Asking their forgiveness if i hurt them in the past. Every single thing that i could do to redeem myself. To turn over a new leaf. I forced myself to do it. If they forgave me then it was good. But if not, at least I've tried asking about it to them than let it became unspeakable matter.

From that, my life became more balanced. Many bad things happened, but so do good things. As i learnt more about life. From action equal to reaction then to Yin Yang, Karma, and the Law of causality. The wall became rock solid resulting in trust issues and another thing was calm mode. It gave me benefits and drawbacks at the same time. I will explain these in  the next post.

OK, the story will continue in part 2. I will update it as soon as it's ready. Stay tune. And thanks for coming. I hope you guys have a bright and happy day. :)

Ending of "Adulthood is Trouble (Part 3)"

Hello everyone, it's me again. I'll continue this topic because it get wrapped up. I mean the story kinda end so fast. Well this help me to ease my minds too. I mean after writing it up, i can address some issues after careful thought. So it is very helpful not only to me and i hope to you as well. Probably.

Alright, let's continue where i left last time. So few months ago, the girl that I've been in touch decided that we really couldn't move forward. The reasons were well, we were all apart for so long and we didn't know each other that much. After that, i tried to give some arguments but she stopped it. After careful thought, i didn't want to give any pressure and made her feel discomfort. So i decided to stop it completely.

Well, in the first place, it is just me. And it will always be me. I am the only one who can manage feeling as i am a sensitive idiot. So. i put them in parts carefully in my heart. This is not their wrongdoing. It is just me who keeps everything in check. And of course, after learning it might be harmful, i pulled myself away. I should have just stopped myself before it was going to happen, so i could keep talking to her non stop.

At that time, some part of me rebel, if it all led down to relationship, then it was better to confess. Another part did rebel too. They reminded me that human were fragile. If i was rejected, then the friendship i built would be lost. And it was right. After i confessed and she rejected, few weeks later  we stopped chatting. I lost a friend that i could talk to. It was bad and good move. Some part of me did regret it, some didn't. Not black nor white, then. How about gray? :)

Well, after that i felt down, but not for long because i was quite good at managing emotions. Not a pro, but definitely not a newbie. I am quite a sensitive person. I get hurt by words so easily. So that was one of things i addressed back in 2012 when i was crushed to dust by "love". Right now, of course i'm still sensitive, but i can manage it carefully, somehow. Every time someone do something that might hurt me, i always activate calm mode, even though there are so many nasty thoughts on  my head, like talking back with rude remarks, or getting angry, or slam my fists to their face, or slay them with katana, or something like that :D, but then still, i keep myself calm. It was bad though, so many emotion got stopped suddenly. I lost the ability to get truly angry. Whenever i got angry, then few seconds later it died down just like that. Too many rationalization and logical thinking made me dull i guess. I will explain about this emotion thingy in the next update. So. please stay tune. :)

Tydac Ada Joedoel?

Baiklah. Setelah selang beberapa waktu kebelakang blog ini dipakai untuk urusan kuliah, sekarang semua itu berakhir. Blog akan kembali saya gunakan untuk membagikan kisah perjalanan hidup yang turun naik. Sepertinya turun terus sih, belum pernah naik. Tapi harus tetap bersyukur pastinya.

Saat ini saya belum bisa bercerita panjang lebar karena belum ada niat untuk memposting draft yang tersimpan di komputer. Tapi tentu saja akan saya mulai kembali. Banyak sekali hal-hal yang terjadi di 2018 ini. Maksudnya, pengalaman-pengalaman yang lebih mengesankan. Pengalaman pahit terutama karena teman, keluarga, saudara jauh dan semacamnya. Lebih ke faktor manusia yang punya hubungan darah.

Mungkin itu saja dari saya. Oh, kebetulan beberapa hari lalu saya diberi tau oleh sahabat tentang lagu dari Alec Benjamin - Let Me Down Slowly. Saat baru pertama kali mendengar di awal-awal, saya langsung suka pada lirik dan musiknya. Seperti ada "chill" efek tapi ada juga kesan "mellow". Pas dengan kondisi yang sedang dialami sekarang. Semoga segera bisa konsisten. Sedang berusaha mendisiplinkan diri. Harus memaksakan, kalau tidak, semuanya tidak akan jalan dan semuanya tidak akan berubah. Okelah kalau begitu, sekian dari saya. See you soon on the next post. It will be completely in English, though. Hehehe.... :)

Perbedaan SSAD dan OOAD

Pada pengembangan suatu sistem informasi ada beberapa metode perancangan, diantaranya yaitu perancangan terstruktur dan berorientasi objek. Disini akan dijelaskan perbedaan antara kedua metode perancangan tersebut.

Perancangan Terstruktur (Structured Analisys and Design / SSAD)

Metode ini diperkenalkan pada tahun 1970, yang merupakan hasil turunan dari pemrograman terstruktur. Metode pengembangan dengan metode terstruktur ini terus diperbaiki sampai akhirnya dapat digunakan dalam dunia nyata.

Perancangan ini bertujuan untuk membuat model SOLUSI terhadap PROBLEM yang sudah dimodelkan secara lengkap pada tahap analisis terstruktur. Ada empat kegiatan perancangan yang harus dilakukan, yaitu:

1. Perancangan arsitektural; kita merancang struktur modul P/L dengam mengacu pada model analisis yang sesuai (DFD). Langkahnya adalah: mengidentifikasi jenis aliran (transform flow atau transaction flow), menemukan batas-batas aliran (incoming flow dan outgoing flow), kemudian memetakannya menjadi striktur hirarki modul. Selanjutnya, kita alokasikan fungsi-fungsi yang harus ada pada modul-modul yang tepat.
2. Perancangan data; kita merancang struktur data yang dibutuhkan, serta merancang skema basisdata dengan mengacu pada model analisis yang sesuai (ERD).
3. Perancangan antarmuka; kita merancang antarmuka P/L dengan pengguna, antarmuka dengan sistem lain, dan antarmuka antar-modul.
4. Perancangan prosedural; kita merancang detil dari setiap fungsi pada modul. Notasi yang digunakan bisa berupa flow chart, algoritma, dan lain-lain

Pastikan bahwa model perancangan yang dibuat sudah mengakomodasi kebutuhan non fungsional.

Berikut ini merupakan kelebihan dan kekurangan metode perancangan terstruktur :

Kelebihan

• Milestone diperlihatkan dengan jelas yang memudahkan dalam manajemen proyek
• SSAD merupakan pendekatan visual, ini membuat metode ini mudah dimengerti oleh pengguna atau programmer.
• Penggunaan analisis grafis dan tool seperti DFD menjadikan SSAD menjadikan bagus untuk digunakan.
• SSAD merupakan metode yang diketahui secara umum pada berbagai industry.
• SSAD sudah diterapkan begitu lama sehingga metode ini sudah matang dan layak untuk digunakan.
• SSAD memungkinkan untuk melakukan validasi antara berbagai kebutuhan
• SSAD relatif simpel dan mudah dimengerti.

Kekurangan

• SSAD berorientasi utama pada proses, sehingga mengabaikan kebutuhan non-fungsional.
• Sedikit sekali manajemen langsung terkait dengan SSAD
• Prinsip dasar SSAD merupakan pengembangan non-iterative (waterfall), akan tetapi kebutuhan akan berubah pada setiap proses.
• Interaksi antara analisis atau pengguna tidak komprehensif, karena sistem telah didefinisikan dari awal, sehingga tidak adaptif terhadap perubahan (kebutuhan-kebutuhan baru).
• Selain dengan menggunakan desain logic dan DFD, tidak cukup tool yang digunakan untuk mengkomunikasikan dengan pengguna, sehingga sangat sulit bagi pengguna untuk melakukan evaluasi.
• Pada SAAD sulit sekali untuk memutuskan ketika ingin menghentikan dekomposisi dan mliai membuat sistem.
• SSAD tidak selalu memenuhi kebutuhan pengguna.
• SSAD tidak dapat memenuhi kebutuhan terkait bahasa pemrograman berorientasi obyek, karena metode ini memang didesain untuk mendukung bahasa pemrograman terstruktur, tidak berorientasi pada obyek (Jadalowen, 2002).

Perancangan Berbasis Objek (Object-oriented Analysis and Design / OOAD)

Metode OOAD melakukan pendekatan terhadap masalah dari perspektif obyek, tidak pada perspektif fungsional seperti pada pemrograman terstruktur. Akhir-akhir ini penggunakan OOAD meningkat dibandingkan dengan pengunaan metode pengembangan software dengan metode tradisional. Sebagai metode baru dan sophisticated bahasa pemrograman berorientasi obyek diciptakan, hal tersebut untuk memenuhi peningkatan kebutuhan akan pendekatan berorientasi obyek pada aplikasi bisnis.

Metode pengembangan perangkat lunak berorientasi objek yang sudah dikenal, dan diantaranya adalah :

• Object Oriented Analysis (OOA) dan Object Oriented Design (OOD) dari Peter Coad dan Edward Yourdon [1990].
• Object Modeling Technique (OMT) dan James Rumbaugh, Michael Blaha, William Premerlan, Frederick Eddy dan William Lorensen [1991].
• Object Oriented Software Engineering (OOSE) dan Ivar Jacobson [1992].
• Booch Method dan Grady Booch [1994].
• Sritrop dan Steve Cook dan John Daniels [1994].
• UML (Unified Modeling Language) dari James Rumbaugh. Grady Booch dan Ivar Jacobson [1997].

Metodologi pengembangan sistem berorientasi objek mempunyai tiga karakteristik utama, yaitu:

1.      Encapsulation

•  Encapsulation merupakan dasar untuk pembatasan ruang lingkup program terhadap data yang diproses.
•  Data dan prosedur atau fungsi dikemas bersama-sama dalam suatu objek, sehingga prosedur atau fungsi lain dari luar tidak dapat mengaksesnya.
•  Data terlindung dari prosedur atau objek lain, kecuali prosedur yang berada dalam objek itu sendiri.

2.      Inheritance

•  Inheritance adalah teknik yang menyatakan bahwa anak dari objek akan mewarisi data/atribut dan metode dari induknya langsung. Atribut dan metode dari objek dari objek induk diturunkan kepada anak objek, demikian seterusnya.
• Inheritance mempunyai arti bahwa atribut dan operasi yang dimiliki bersama di anatara kelas yang mempunyai hubungan secara hirarki.
•  Inheritance menggambarkan generalisasi sebuah kelas.

3.     Polymorphism

•  Polimorfisme yaitu konsep yang menyatakan bahwa sesuatu yang sama dapat mempunyai bentuk dan perilaku berbeda.
•  Kemampuan objek-objek yang berbeda untuk melakukan metode yang pantas dalam merespon message yang sama.
•  Seleksi dari metode yang sesuai bergantung pada kelas yang seharusnya menciptakan objek.

Kelebihan dan kekurangan dari metode perancangan ini adalah sebagai berikut :

Kelebihan

• Dibandingkan dengan metode SSAD, OOAD lebih mudah digunakan dalam pembangunan sistem
• Dibandingkan dengan SSAD, waktu pengembangan, level organisasi, ketangguhan,dan penggunaan kembali (reuse) kode program lebih tinggi dibandingkan dengan metode OOAD (Sommerville, 2000).
• Tidak ada pemisahan antara fase desain dan analisis, sehingga meningkatkan komunikasi antara user dan developer dari awal hingga akhir pembangunan sistem.
• Analis dan programmer tidak dibatasi dengan batasan implementasi sistem, jadi desain dapat diformliasikan yang dapat dikonfirmasi dengan berbagai lingkungan eksekusi.
• Relasi obyek dengan entitas (thing) umumnya dapat di mapping dengan baik seperti kondisi pada dunia nyata dan keterkaitan dalam sistem. Hal ini memudahkan dalam mehami desain (Sommerville, 2000).
• Memungkinkan adanya perubahan dan kepercayaan diri yang tinggi terhadap kebernaran software yang membantu untuk mengurangi resiko pada pembangunan sistem yang kompleks (Booch, 2007).
• Encapsliation data dan method, memungkinkan penggunaan kembali pada proyek lain, hal ini akan memperingan proses desain, pemrograman dan reduksi harga.
• OOAD memungkinkan adanya standarisasi obyek yang akan memudahkan memahami desain dan mengurangi resiko pelaksanaan proyek.
• Dekomposisi obyek, memungkinkan seorang analis untuk memcah masalah menjadi pecahan-pecahan masalah dan bagian-bagian yang dimanage secara terpisah. Kode program dapat dikerjakan bersama-sama. Metode ini memungkinkan pembangunan software dengan cepat, sehingga dapat segera masuk ke pasaran dan kompetitif. Sistem yang dihasilkan sangat fleksibel dan mudah dalam memelihara.

Kekurangan

• Pada awal desain OOAD, sistem mungkin akan sangat simple.
• Pada OOAD lebih fockus pada coding dibandingkan dengan SSAD.
• Pada OOAD tidak menekankan pada kinerja team seperti pada SSAD.
• Pada OOAD tidak mudah untuk mendefinisikan class dan obyek yang dibutuhkan sistem.
• Sering kali pemrogramam berorientasi obyek digunakan untuk melakukan anlisisis terhadap fungsional siste, sementara metode OOAD tidak berbasis pada fungsional sistem.
• OOAD merupakan jenis manajemen proyek yang tergolong baru, yang berbeda dengan metode analisis dengan metode terstruktur. Konsekuensinya adalah, team developer butuh waktu yang lebih lama untuk berpindah ke OOAD, karena mereka sudah menggunakan SSAD dalam waktu yang lama ( Hantos, 2005).
• Metodologi pengembangan sistem dengan OOAD menggunakan konsep reuse. Reuse merupakan salah satu keuntungan utama yang menjadi alasan digunakannya OOAD. Namun demikian, tanpa prosedur yang emplisit terhadap reuse, akan sangat sliit untuk menerapkan konsep ini pada skala besar (Hantos, 2005)

Apa itu Fiksi dan Fiktif?

Baru-baru ini jagat maya dihebohkan dengan pernyataan seseorang yang menyebut, "Kitab suci itu adalah fiksi." Begitu banyak respon pro maupun kontra akan pernyataan ini. Namun saya tak akan membahas hal tersebut. Saya akan membahas apa itu Fiksi atau Fiktif. Dan apa lawan kata yang sebenarnya untuk kedua kata tersebut. Karena banyak sekali berseliweran di beranda Facebook ataupun Twitter pembelaan membabi buta tanpa menelaah tentang kedua kata tersebut.

Menurut KBBI, fiksi adalah sebuah nomina (kata benda) yang mempunya beberapa arti. Pada bidang Sastra berarti sebuah cerita rekaan (roman, novel, dan sebagainya); 2 rekaan; khayalan; tidak berdasarkan kenyataan: nama Frank Castle (The Punisher) adalah nama tokoh komik -- , bukan tokoh sejarah; 3 pernyataan yang hanya berdasarkan khayalan atau pikiran.

Nah sedangkan fiktif menurut KBBI adalah sebuah kata adjektiva, sehingga dapat dikatakan bahwa fiktif itu adalah hal yang bersifat fiksi. Dari sini sangat jelas kedua kata ini memiliki arti kata yang mirip, hanya penempatannya saja pada kalimat yang membuatnya berbeda. Kata fiksi diletakkan pada kata benda sendangkan kata fiktif diletakkan pada kata sifat.

Untuk antonim (lawan kata) dari fiksi yaitu nonfiksi.  Namun jika belum yakin, kita perlu mencari sinonim dari fiksi itu sendiri. Yang paling dekat yaitu Fantasi. Bisa dilihat dari arti kata tersebut terdapat kemiripan yang cukup. Lawan kata fantasi adalah realitas. Jadi, sebaiknya sebelum berdebat atau beropini ada baiknya jika teman-teman para pembaca dapat mencari arti suatu kata terlebih dahulu. Karena pembelokkan fakta sering sekali terjadi. Website KBBI sangat informatif. Pada website tersebut juga tidak terdapat iklan. Simple dan bermanfaat.

Sistem Analis, Analisis Sistem dan Desain Sistem

Hello again. Postingan kedua hari ini membahas sedikit rangkuman dari Sistem Analis, Analisis Sistem dan Desain sistem.

Nah, mari kita mulai. Pertama, yang dimaksud dengan Analisis Sistem adalah penguraian suatu sistem informasi yang sudah utuh kedalam bagian-bagian komponennya dengan tujuan dapat menidentifikasi dan mengevaluasi berbagai macam permasalahan maupun hambatan yang terjadi pada sistem sehingga nantinya dapat dilakukan perbaikan atau pengembangan. Tahapannya sebagai berikut:

a. Mengidentifikasi Masalah

Identifikasi masalah merupakan langkah awal dari analisa sistem. Dalam tahap ini didefinisikan masalah yang harus dipecahkan dengan munculnya pertanyaan yang ingin dipecahkan.

b. Memahami Kerja Sistem yang Ada

Langkah ini dilakukan dengan mempelajari secara rinci bagaimana sistem yang sudah ada berjalan. Untuk mempelajari operasi dari sistem ini diperlukan data yang dapat diperoleh dengan melakukan penelitian terhadap sitem.

c. Menganalisis Sistem

Berdasarkan data yang sudah diperoleh maka dilakukan analisa hasil penelitian yang sudah dilakukan untuk mendapatkan pemecahan masalah yang akan dipecahkan

d. Membuat Laporan

Laporan perlu dibuat sebagai dokumentasi dari penelitian. Tujuan utamanya adalah sebagai bukti secara tertulis tentang hasil analisa yang sudah dilakukan.

Sedangkan orang atau kelompok yang melakukan perancangan dan perbaikan pada suatu sistem disebut Sistem Analis. Sistem analis merupakan individu ataupun kelompok yang melakukan pengembangan sistem. Sistem analis mempelajari permasalahan maupun kebutuhan pada suatu sistem. Sistem analis juga merupakan orang yang bertanggung jawab terhadap proses analisa maupun perancangan pada sistem informasi.

Setelah pengertian tadi, inilah langkah-langkah kerja dari sistem analis, diantaranya meliputi:

a. Melakukan identifikasi permasalahan pada sistem.

b. Melakukan studi kelayakan dan memahami kinerja dari sistem yang ada.

c. Melakukan analisis dan perancangan sistem.

d. Melakukan penerapan sistem.

e. Melakukan evaluasi dan pemeliharaan pada sistem.

Selanjutnya, desain sistem adalah tahap setelah analisis sistem. Kita mendefinisikan dari kebutuhan-kebutuhan fungsional. Kemudian mempersiapkan untuk rancang bangun implementasi. 

Menggambarkan bagaimana suatu sistem dibentuk. Setelah mendapatkan penggambaran, kita merencanakan dan membuat sketsa atau pengaturan dari beberapa elemen yang terpisah ke dalam satu kesatuan yang utuh dan berfungsi. Termasuk lah pengkonfigurasian dari komponen-komponen perangkat lunak dan perangkat keras dari suatu sistem. 

Tujuannya untuk memenuhi kebutuhan pemakai sistem dan memberikan gambaran yang jelas dan rancang bangun yang lengkap kepada pemrogram komputer dan ahli teknik yang terlibat.

Model-model pada Software Development Life Cycle (SDLC)

Hello, kali ini saya akan membahas model-model yang digunakan pada Software Development Life Cycle (SDLC). Langsung saja, saya akan menampilkan definisi beserta contoh gambar agar mudah dipahami. 

a.    Model Waterfall

Merupakan model pengembangan system yang paling mudah dan paling sering digunakan. Model pengembangan ini bersifat linear dari tahap awal pengembangan system yaitu tahap perencanaan sampai tahap akhir pengembangan system yaitu tahap pemeliharaan. Tahapan berikutnya tidak akan dilaksanakan sebelum tahapan sebelumnya selesai dilaksanakan dan tidak bisa kembali atau mengulang ke tahap sebelumnya. Tahap-tahap yang dilakukan pada model Waterfall ini digambarkan pada gambar berikut ini :

b.    Model Iterasi

Merupakan model pengembangan system yang bersifat dinamis dalam artian setiap tahapan proses pengembangan system dapat diulang jika terdapat kekurangan atau kesalahan. Setiap tahapan pengembangan system dapat dikerjakan berupa ringkasan dan tidak lengkap, namun pada akhir pengembangan akan didapatkan system yang lengkap pada pengembangan system. Terdapat dua jenis model iterasi, yaitu :

–        Model Incremental, merupakan model pengembangan system yang dipecah sehingga model pengembangannya secara increment/bertahap. Kebutuhan pengguna diprioritaskan dan prioritas tertinggi dimasukkan dalam awal increment. Model Incremental digambarkan sebagai berikut :

–        Model Spiral, merupakan model pengembangan system yang digambarkan berupa spiral. Model spiral ini tidak merepresentasikan rangkaian tahapan dengan penelusuran balik (back-tracking), tidak ada fase-fase tahapan yang tetap seperti spesifikasi atau perancangan. Setiap untaian pada pada spiral menunjukkan fase software process. Model Spiral ini digambarkan sebagai berikut :

c.    Model Rapid Application Development (RAD)

Merupakan model pengembangan system yang melakukan beberapa penyesuaian terhadap SDLC pada beberapa bagian sehingga lebih cepat untuk sampai ke tangan pengguna system. metodologi ini biasanya mensyaratkan beberapa teknik dan alat-alat khusus agar proses bisa cepat, misalnya melakukan sesi Joint Application Development (JAD), penggunaan alat-alat Computer Aided Software Engineering (CASE Tools), kode generator dan lain-lain. Model RAD ini digambarkan sebagai berikut :

d.    Model Prototyping

Merupakan model pengembangan system yang proses iterative dalam pengembangan sistem dimana requirement diubah ke dalam sistem yang bekerja (working system) yang secara terus menerus diperbaiki melalui kerjasama antara user dan analis. Prototype juga bisa dibangun melalui beberapa tool pengembangan untuk menyederhanakan proses. Prototyping merupakan bentuk dari Rapid Application Development (RAD). Model Prototypig digambarkan sebagai berikut :

Apa itu Analis, Analisis dan Analisa?

Hello semua untuk para pembaca, pertama-tama saya mohon maaf karena sudah lama tidak muncul padahal sudah bilang ingin aktif ngeblog sejak tahun lalu. Namun apa daya, web sebelah lebih menarik namun akhirnya diblokir kemkominfo, jadi balik lagi kesini. Well, let's skip that.

Jadi saya dapat tugas dari dosen untuk mencari perbedaan analis, analisis dan analisa. Setelah googling sana sini dan membaca berbagai sumber saya dapat mengambil sebuah kesimpulan.

Analis menurut KBBI (Kamus Besar Bahasa Indonesia) adalah orang yang menganalisis atau melakukan analisis; ahli ilmu kimia yang bekerja di laboratorium (menjalankan penyelidikan dan sebagainya); orang yang mencari dan mengumpulkan data untuk penilaian kekayaan atau kemampuan perusahaan demi kepentingan pemodal. Nah menurut saya ini cukup jelas. Sebab terdapat tiga definisi yang mengarah ke siapa itu analis dan didapatlah jawaban diatas.

Selanjutnya, apa itu analisis atau analisa? Pertanyaan ini lah yang membuat kami mahasiswa berpikir ulang saat ingin menjawab. Sebab di masyarakat terjadi banyak penggunaan kata analisis ataupun analisa. Namun ketika melakukan pencarian di kbbi.web.id yang muncul hanyalah analisis. Menurut KBBI analisis adalah penyelidikan terhadap suatu peristiwa (karangan, perbuatan, dan sebagainya) untuk mengetahui keadaan yang sebenarnya (sebab-musabab, duduk perkaranya, dan sebagainya); penguraian suatu pokok atas berbagai bagiannya dan penelaahan bagian itu sendiri serta hubungan antarbagian untuk memperoleh pengertian yang tepat dan pemahaman arti keseluruhan; penyelidikan kimia dengan menguraikan sesuatu untuk mengetahui zat bagiannya dan sebagainya; penjabaran sesudah dikaji sebaik-baiknya; pemecahan persoalan yang dimulai dengan dugaan akan kebenarannya. Dari pengertian di KBBI cukup jelas tentang apa itu analisis.

Kata baku dari analisis atau analisa adalah analisis. Disini selain terjawab melalu pencarian KBBI juga bisa dijawab mengenai kaidah penulisan Bahasa Indonesia. Menurut Pedoman Umum Pembentukan Istilah (PUPI), kata dengan sufiks atau akhiran –sis (dalam bahasa Inggris) diserap ke dalam bahasa Indonesia menjadi –sis, dan bukan –sa. Analisis adalah istilah yang tepat untuk menyerap kata analysis. Mungkin kata analisa muncul sebab diserap dari kata Bahasa Inggris Analyse sehingga terjadi kesalahan yang sering terjadi. Setelah ini penulis berharap untuk diri pribadi maupun pembaca tidak melakukan kesalahan lagi dalam penulisan kata Analisis. Semoga bermanfaat.

Ruination?

Hello dear readers, it has been a while. I already wrapped things up. Well, after the new event, i wrote the next post already. But, as my emotions fluactuated much, i decided to postpone the release.

Well let's skip that part. few weeks ago i started a holiday trip with my brothers and sisters. We are 7 with my older sister's husband and their child. So, we can count it as 9 people. I will explain about my adventures with them in 1 or 2 post ahead. I will give reviews about the hotel i visit, the foods and the places.

What's more important then to tell beside my holiday? I don't know how to explain it. The only thing i can tell is, i get cut before even starting. I haven't even give time to really focus on there. Really, it upset me. Not that much, though, I don't know what kind of things that ruin my part. Is it about looks? Is it about money? Is it about attitude? I don't know. And i don't think i will have the real answer. Let's stop it at there about my assumptions. I will not start to ramble about things that i don't investigate. Sad, isn't it? Of course it is. I haven't thought about this even once until three weeks ago. Yet, i have to let it go just like that again. Again? Yes, again.

It was hard to part away with it. I had to make decision as fast as i can. Yet, i wanted it to last as long as possible. Because it would be the last time that we could have long talk together. Regardless, about things that we talked. I believed that, after i made the decision, we would not talk again. Back to being acquaintance. This is the saddest part for me. Because it happened in the past. Acquaintance. Nothing more, nothing less. We used to be so close. It was hard to find someone like you. Even after i looked around for so long. I haven't even encounter one beside you. Someone that really fit with what i wanted. But i have to understand too, that i can't force someone to like me. Not to mention my personality which is like this. A really huge and thick wall that always filter everything before me. That might turned off people before we even began.

Alright, in every chance, i have to acquire lessons to learn. Sincerity, sometimes can't move people, no matter how pure of it. Maybe it will, maybe it will not. Because, we can't see what's inside someone's heart. Some will fail to interpret it and even misinterpret. And sometimes, you will end up like you are lying. Well, it is ok. Maybe even normal. Because i really don't know, maybe common sense is too hard to grasp. As i said in the past, not everyone could handle raw truths. Not to mention young generation, even the old generation suffer from it too. Maybe because it is rare in society nowadays to speak up and have different opinions.

I think that's all for now. As the situation is cooling down. I will try to post the drafts i have. I'm sorry, i can't explain much. I really can't explain because i already said that i would keep it between us. Well, i really don't know what's to keep. Is it about our secret? Yet, i don't know what's secret that we have. Is it about us? I haven't started yet. Is it about our break up? Yet we are not even in any kind of relationship. Really, i don't know. I'm back to suppress this long-lasting feeling. It has been here for years. And maybe it is time to really let it go. Should i low level format my heart then? Or should i show that i am not playing around? Time will tell.

Adulthood is Trouble (Part 3)

Hello again. It's me. Obviously. Alright, I'm going to address the third issues in my life. From two previous post before, they were the major things that pull my life over. I mean, it was like they came just like the storm, came, wrecked around, and went away. As hectic as that. lol.

Alright, the third topic will be romance. Why i put it last? Because i posted the previous things based on category from the hardest, medium and easiest. The romance will be the easiest because i don't think that i care that much about it. My heart, it is hollow, i think....

In recent years, i met dozens of woman. I really wanted to look around. And from that i got 2 girls. Of course, they were not in any special relationship with me. It was just targets. I told you about both of them in the past. You guys can check this post. It was the latest post (aside from poem) about my life story, before i changed my blog's function to do assignment for college.

Now, there are none left. HAHAHA.... It is not that i don't want to be in relationship at all. Of course i wanted that, i tried it at first. Chit chat. Meetings. And so on. I thought that because i haven't been in any real relationship since 2012, I've become rusted. It is hard for me to express things. Especially to girls. I thought that they must have known my obvious intention from start. So after some time, either i backed down or they became astral. I mean, they were going away too.

I've been single for 5 years if i counted this year. And it is hard to really start a new relationship. Well, girls that I've met, most of them didn't know about what's going in this world. I mean they were stuck on their own world. They haven't experienced how cruel the world is. They enjoyed their time zone. It is good thing. I'm not judging them. It's just they are too naive and that is not the type that I'm looking for. I'm not ready for stupid small drama things. I know, life is full of dramas, but useless dramas that will not improve our life, what's the use of it?

I really just walk on my own pace. Even when my family ask about it, i always answer that,"I'm not yet ready to look for one. I already have too many problems. And if we add our own family's circumstances, i don't even know if she can endure it." Yeah, another reason that i haven't look for girlfriend because of that too. I'm afraid because there are so many problems that going on, i will only make her uncomfortable. I will be just too focused on my own problems and neglect her. I don't want to hurt anybody again. I already experience how hurt it can be.

I really wash away the idea of finding girlfriend. Until few weeks ago. The girl that i always wait for her presence. The girl that i admire so much because of her solid background. Solid in here, because she worked her way up, without any shortcut. A girl who walk from bottom, and rise with time even now. A girl that have big heart. A girl that have special place in me for the longest as far as i can remember. A girl that often visit my dream. A girl that used to influence how should i reached the sky. A girl that i really treat as carefully as i can. A girl that i consider as the wisest as a girl in my generation that i met in almost 24 years of life. It sounds like i exaggerated. But it is not. I replayed many questions that dozens of girls, even 2 best candidates i considered the best in the past, and they all answered naively. Yet she answered it on point without even breaking a sweat and the answers were so reasonable and logically true as i experienced. Conclusion? unrivaled. :)

Maybe, i just haven't met her rival yet. She "whipped" me so hard that i want to finish my college as fast as possible. And work towards my dreams. Burning me with high spirits. I hope this time, i can finally put my expectations and hopes on another human. Eventhough it is impossible. And will end up, i get hurt again. It's totally worth this time. I won't blame anyone but myself on this decision. And i believe, I will not meet any girl with her qualities anytime soon.

Few last paragraph was not planned at all. lol. That's all i could think of. I will write as soon as i can. And i hope, i will already walk together in line with her next time i post new stuffs. lol. Just kidding. Alright, have a great weekend everyone. :)
