My study vitamin!

My study vitamin!

it’s undoubted that music took an important part for us, students. Especially us whom are often stay up on late night doing assignments until our brain cramp. We definitely need music to avoid these brain cramp thingy.

As for me, i like to study while being accompanied with 8tracks. 8tracks is an online radio streaming that plays lots of playlist which were made by another people across the world (and you can make your own too!). Therefore, i often find some musics that i’ve never heard before but the sound’s clingy for my ears. It’s a perfect way for me, the one who seldom to download and update my music on my itunes, to hear various songs while studying so i won’t be get bored and keep spirited up :D

Oh, it also provides playlist which are especially made for us, students, a study vitamin which is mostly contain classical or instrumental musics that optimizes our brain (and that kind of musics are scientifically proven to be able to do that). But i never listened to this kind of playlist to study because it gives me goosebumps instead of giving me more concentration on my study :(

My current favorite playlist is this one and i looooooooove it so much :) It contains lots of love songs and i love it. I also love the person who told me about this 8tracks for the 1st time very much, hihi :”>

Anyway, happy studying for myself, may i finish all of these craps very very soon. And happy studying for you people who (kindly) read this post and then being interested to try this 8tracks :) May our study will easily done, as easy as loving someone who is very dear for us. #sokpunchline #ngasal

What i like the most about graduation on my campus is it’s the time when people gathering around and taking lots of pictures with their friend, including me. Most of my facebook’s profile pictures are taken on the night party that we always have before the graduation or on the graduation day itself. Perhaps the reason why i’m looking so good on the picture that’s taken on that time is because i was having fun on that time and that makes a smile always appears on my face. And we all know that a smile is the best accessories a girl could ever wore :)

These 2 photos are taken with my fuji instax wide 210. These are the moments that we had for the April’s graduation day. April? April May June… July. And then we’ll have another graduation day on July. Oh great, another chance to take a lots of another nice pictures with friends <3

But then i realized…. It’ll be July, in the year of 2012. Which clearly means that it’s supposed to be my year’s turn to be graduated. 3 more months and then some of my friends or even perhaps myself, will be graduated and then leave. And then it’ll be the last time we’ll be able to take these kind of pictures together. The. Last. Time.

It’s true, life goes so fast. But we never wanted any of our precious moments to be ended, and so did i. For me, the time that i had in college is the best time i’ve ever had. It’s even more fun, educating, and precious than when i’m in high school (of course, i was kinda a dork when i’m still in high school haha *i never been proud of it, but am still bragging about it until now, silly me*).

Soon, this semester’s gonna be over and it’ll be the last one. And on July, we’ll have another graduation party. Or more like a farewell party. Yes, i’m gonna having a farewell party with my friends. And then the day after they’ll be officially graduated from the campus, and then leave. I know that i’m supposed to feel happy about it. No more freaking assignments on the late night, no more non-sense tests, no more that anxious feeling when you’re about the see your final score. But that would be mean, no more laughter and crazy fun chatter that we always had on the night while working on our assignment, no more bullying you’re most retarded friend or even being bullied until you cry, no more heart-to-heart conversation with your friends.

Oh, i’m definitely gonna miss that moments. But when the time has come, i’ll definitely give my best smile to say “Good bye, see you again later” to my friends. And then i’ll definitely cry. And that’s why i’m not very sure on July’s graduation i’ll change my facebook’s profile picture (the pictures won’t be any good i guess… haha).

Well, ready or not, the time will come for sure. So we must prepare our heart to face this. And last but not least, we should also prepare our (freaking) thesis to be done soon. Real soon. Argh.

Stupid conversation #1

Stupid conversation #1

so this is one of many conversations i had yesterday. In that day, my mind met a dead end while i was in the middle work for my assignment. thankfully i knew that one of my friends has finished from twitter, and so then i contacted him via bbm. Here’s the stupid conversation we had

Me: Jin

J: apa?

Me: si Fathur gimana caranya bisa baca mathcad tp gak punya mathcad? setau gw dia pake excel deh

J: gw ngirim pdf cika cantik

Me: oooh. Akoh jg mau atuh dikirimin :3 da bageur

J: bawahaha. akika lagi gereja cika manis. Nanti deh kalo gw udah di kosan

Me: Hooo. Oke deh

J: okeeee

Me: maaci yaa :3

J: sama2 cika

*10 detik kemudian*

Me: kalo di gereja kudu memuji terus yah kalo ngomong btw? *tumben ngomongnya manis pake bilang cantik segala*

J: bwahahahahahahahahahahaha babi. anjir ngakak gua.

Me: oh ngga ternyata .____.

J: tae lo cik

Me: abis lo aneh sih .____.

Subsea Pipelines

Subsea Pipelines

Dari namanya saja pasti sudah jelas tipe pipeline apa yang saya maksud. Pipeline yang kali ini akan saya jelaskan bukan pipa-pipa paralon berwarna abu yang sering sekali dijumpai di rumah, bukan juga pipa-pipa bawah tanah yang sering kita lihat bila ada perbaikan saluran/kabel listrik di jalanan

Pipeline yang akan saya jelaskan kali ini  menjadi salah satu bidang keahlian di jurusan saya (Teknik Kelautan), dan bisa dibilang bahwa bidang  yang satu ini mulai banyak peminatnya di jurusan saya karena memang sedang booming di dunia kerja :p #agaksotoy

Subsea Pipelines

sumber: http://rahmat88aceh.wordpress.com/2010/09/04/pipa-bawah-laut-submarine-pipeline/

Sebuah sistem pipeline yang terletak di bawah laut. Kalau dilihat dari gambar di atas mungkin terlihat seperti pipa biasa yang dibentangkan begitu saja di bawah laut. But the truth is, there’s complexity that lies behind it’s humble appearance. In fact, designing subsea pipelines is a lot harder than designing underground pipelines. Kenapa? Ini beberapa alasan utamanya (menurut saya):

1. Tidak seperti pipa di daratan, pipa bawah laut harus didesain kuat untuk menahan tekanan hidrostatis yang disebabkan oleh air laut. Semakin besar kedalaman lokasi subsea pipeline, maka tekanan hidrostatisnya pun akan semakin besar.

2. Air laut mempunyai efek korosif yang lebih besar dibandingkan air biasa

dan proses desain subsea pipeline ini semakin rumit karena engineer harus mendesain pipeline yang kuat untuk 3 macam kondisi (beban), yaitu:

1. Kondisi saat pipeline masih kosong. Maksudnya adalah kondisi saat pipeline sudah terinstalasi tapi belum beroperasi (pada kondisi ini pipeline akan menahan tekanan hidrostatik dari luar saja)

2. Kondisi saat pipeline beroperasi (pipeline mengalami tekanan dari dalam dan tekanan hidrostatik dari luar)

3. Kondisi saat pipeline terkorosi (pipeline sudah beroperasi, tetapi mengalami korosi pada bagian dalam pipa yang menyebabkan berkurangnya kekuatan pipa)

Metode penggelaran pipa (Pipe laying method)

sudah jelas, metode instalasi subsea pipelines ini sangat berbeda dengan metode instalasi pipeline di darat.

Subsea Pipeline difabrikasi/dibuat di darat. Dan pipeline tersebut difabrikasi per segmen. Jadi misalnya ada proyek pembuatan pipeline sepanjang 50km dan pipeline didesain dengan panjang segmen 20 meter. Maka akan ada total 2500 segmen pipa baja yang harus difabrikasi di darat.  Setelah itu pipa baja akan mengalami proses coating/pelapisan (biasanya dilapisi dengan beton) agar pipa tersebut terlindungi dari faktor luar seperti benturan dan korosi pada bagian luar. Setelah proses coating selesai, selanjutnya hydro test akan dilakukan pada pipa untuk mengetahui apakah terjadi kebocoran pada pipa tersebut atau tidak.

Setelah proses fabrikasi selesai, pipa-pipa tersebut akan diangkut ke lokasi instalasi dengan menggunakan barge. Di lokasi instalasi nanti, akan ada sebuah vessel khusus instalasi pipeline (pipe lay vessel) yang beroperasi di sana. Sebelum digelarkan, pipa-pipa baja ini akan disambungkan terlebih dahulu di station-station yang ada di pipe lay vessel. Station-station ini beragam dan mempunyai fungsi yang bermacam-macam juga. Jenis-jenis station ini dapat dilihat secara lengkap di link ini —-> http://www.youtube.com/watch?v=EyrdjqEiTZc

Secara garis besar sih, ada 3 macam station yang harus dilalui pipa-pipa ini, yaitu:

1. Welding station: berfungsi untuk menyambungkan/mengelas sambungan joint pipa-pipa

2. AUT ( Automated Ultrasonic Testing) Station: berfungsi untuk mengecek apakah terjadi kebocoran pada joint pipa yang disambungkan atau tidak

3. Coating Station: berfungsi untuk memberikan lapisan pelindung pada joint pipa yang baru dilas

Setelah melewati station-station tersebut, pipeline sudah siap untuk digelarkan dan diinstalasi di seabed :D

Metode instalasi pipeline ada 3 macam yaitu S-Lay, J-Lay, dan Reel Lay

berikut ini adalah artikel yang lumayan lengkap tentang metode laying pipeline (maaf dalam bahasa inggris, gak nemu lagi yang lebih lengkap dan bisa dicopas)

Sumber: http://www.rigzone.com/training/insight.asp?insight_id=311&c_id=19

Laying pipe on the seafloor can pose a number of challenges, especially if the water is deep. There are three main ways that subsea pipe is laid — S-lay, J-lay and tow-in — and the pipelay vessel is integral to the success of the installation.

Buoyancy affects the pipelay process, both in positive and negative ways. In the water, the pipe weighs less if it is filled with air, which puts less stress on the pipelay barge. But once in place on the sea bed, the pipe requires a downward force to remain in place. This can be provided by the weight of the oil passing through the pipeline, but gas does not weigh enough to keep the pipe from drifting across the seafloor. In shallow-water scenarios, concrete is poured over the pipe to keep it in place, while in deepwater situations, the amount of insulation and the thickness required to ward of hydrostatic pressure is usually enough to keep the line in place.

Tow-In Pipeline Installation

While jumpers are typically short enough to be installed in sections by ROVs, flowlines and pipelines are usually long enough to require a different type of installation, whether that is tow-in, S-lay or J-lay.

Tow-in installation is just what it sounds like; here, the pipe is suspended in the water via buoyancy modules, and one or two tug boats tow the pipe into place. Once on location, the buoyancy modules are removed or flooded with water, and the pipe floats to the seafloor.

Surface Tow Pipeline Installation

Surface Tow Pipeline InstallationSource: www.pipelife.no

There are four main forms of tow-in pipeline installation. The first, thesurface tow involves towing the pipeline on top of the water. In this method, a tug tows the pipe on top of the water, and buoyancy modules help to keep it on the water’s surface.

Using less buoyancy modules than the surface tow, the mid-depth tow uses the forward speed of the tug boat to keep the pipeline at a submerged level. Once the forward motion has stopped, the pipeline settles to the seafloor.

Off-bottom tow uses buoyancy modules and chains for added weight, working against each other to keep the pipe just above the sea bed. When on location, the buoyancy modules are removed, and the pipe settles to the seafloor.

Lastly, the bottom tow drags the pipe along the sea bed, using no buoyancy modules. Only performed in shallow-water installations, the sea floor must be soft and flat for this type of installation.

S-Lay Pipeline Installation

When performing S-lay pipeline installation, pipe is eased off the stern of the vessel as the boat moves forward. The pipe curves downward from the stern through the water until it reaches the “touchdown point,” or its final destination on the seafloor. As more pipe is welded in the line and eased off the boat, the pipe forms the shape of an “S” in the water.

S-Lay Pipeline Installation

S-Lay Pipeline InstallationSource: www.pbjv.com.my

Stingers, measuring up to 300 feet (91 meters) long, extend from the stern to support the pipe as it is moved into the water, as well as control the curvature of the installation. Some pipelay barges have adjustable stingers, which can be shortened or lengthened according to the water depth.

Proper tension is integral during the S-lay process, which is maintained via tensioning rollers and a controlled forward thrust, keeping the pipe from buckling. S-lay can be performed in waters up to 6,500 feet (1,981 meters) deep, and as many as 4 miles (6 kilometers) a day of pipe can be installed in this manner.

J-Lay Pipeline Installation

Overcoming some of the obstacles of S-lay installation, J-lay pipeline installation puts less stress on the pipeline by inserting the pipeline in an almost vertical position. Here, pipe is lifted via a tall tower on the boat, and inserted into the sea. Unlike the double curvature obtained in S-lay, the pipe only curves once in J-lay installation, taking on the shape of a “J” under the water.

J-Lay Pipeline Installation

The reduced stress on the pipe allows J-lay to work in deeper water depths. Additionally, the J-lay pipeline can withstand more motion and underwater currents than pipe being installed in the S-lay fashion.

Types Of Pipelay Vessels

There are three main types of pipelay vessels. There are J-lay and S-lay barges that include a welding station and lifting crane on board. The 40- or 80-foot (12- or 24-meter) pipe sections are welded away from wind and water, in an enclosed environment. On these types of vessels, the pipe is laid one section at a time, in an assembly-line method.

On the other hand, reel barges contain a vertical or horizontal reel that the pipe is wrapped around. Reel barges are able to install both smaller diameter pipe and flexible pipe. Horizontal reel barges perform S-lay installation, while vertical reel barges can perform both S-lay and J-lay pipeline installation.

Vertical Reel Barge

Vertical Reel BargeSource: www.jee.co.uk

When using reel barges, the welding together of pipe sections is done onshore, reducing installation costs. Reeled pipe is lifted from the dock to the vessel, and the pipe is simply rolled out as installation is performed. Once all of the pipe on the reel has been installed, the vessel either returns to shore for another, or some reel barges are outfitted with cranes that can lift a new reel from a transport vessel and return the spent reel, which saves time and money.

Pendek kata,

S-Lay method adalah metode penggelaran pipeline yang sering digunakan untuk perairan yang tidak terlalu dangkal. Posisi stinger cenderung lebih horizontal.Pipeline akan seolah membentuk huruf S pada saat proses penggelaran

J-Lay method adalah metode penggelaran pipeline yang sering digunakan untuk perairan dalam. Posisi stinger cenderung lebih vertikal. Pipeline akan seolah membentuk huruf J pada saat proses penggelaran.

Reel Lay method adalah metode yang sering digunakan untuk instalasi flexible pipeline. Ciri-ciri yang paling menonjol adalah adanya gulungan reel pipe pada pipe lay vessel.

Free Span  dan Crossing Pada Pipeline

Dalam perancangan pipeline, ada beberapa bagian penting yang perlu diperhatikan. Beberapa bagian tersebut antara lain:

- tebal dinding (wall thickness) pipa

- pemilihan material (material selection),

- peninjauan rute (route survey),

- pemilihan rute (route selection),

- data lingkungan (environmental data),

- perlindungan katodik (cathodic protection) terhadap korosi,

- kestabilan pada permukaan bawah laut (on-bottom stability),

- analisis tekuk (buckling analysis),

- ekspansi termal (thermal expansion),

- analisis lelah (fatigue analysis), dan

- analisis terhadap bagian pipa yang tidak tertumpu (span analysis)

Free Span pada pipeline adalah bagian pipeline yang tidak tertumpu / tidak menyentuh seabed. Untuk lebih jelasnya dapat dilihat pada gambar di bawah ini

sumber: http://pipelineengineering.blogspot.com/2009/05/free-span.html

Sebaiknya jumlah free span pada pipeline tidak terlalu banyak karena semakin banyak free span yang tercipta pada pipeline, maka semakin besar kemungkinan pipeline tersebut akan runtuh (karena getaran dapat terjadi dan mempengaruhi free span. dikhawatirkan getaran tersebut akan mencapai natural frequency dari pipeline dan kemudian pipeline akan hancur)

Pipeline crossing?

Pipeline crossing ini biasanya terjadi saat 2 rute pipeline (pipeline existing dan pipeline desain misalnya) saling bertemu di satu point. Salah satu ketentuan dari pipe crossing adalah sudut yang dibetuk antar pipeline minimal 30 derajat. Selain itu, harus terdapat straight line kira-kira sepanjang 500 m  agar crossing tersebut aman dan stabil.

untuk lebih jelasnya, bisa dilihat di referensi di bawah ini (sekali lagi maaf, in english :p)

Sumber: http://fishsafe.eu/en/offshore-structures/pipelines.aspx

Pipeline Crossings

Where two pipelines have to cross over each other there is a need to provide some protection to the pipeline crossing. There are several ways which this can be achieved. Protection is mostly provided at crossings by laying small pieces of rock to form a bridge over the bottom pipeline which in turn is covered by rock. This method is undertaken using a rock placement vessel, as seen in the picture to the right.These specialist vessels are capable of laying the rock in exactly the correct location, direct from the surface. Stone mattresses may also be used in conjunction with rock placement, as seen in the image below.

Pipeline Spans

When pipelines are installed, great care is taken to ensure they are as safe as possible to other seabed users. However, due to an uneven seabed, tidal currents or scouring, some pipelines may develop free spans. A free span on a pipeline is where the seabed sediments have been eroded, or scoured away and the pipeline is no longer supported on the seabed (see image below).

Pipline freespan Freespan trawldoor

When this occurs, the pipelines present a serious danger to fishing activity, especially trawl doors, clump weights or any towed gear, as they can become trapped under the pipeline and will be extremely difficult to recover. In 1997 a Scottish fishing vessel was lost as a result of becoming fast under a pipeline span. Spans that are considered dangerous to fishing activities are shown on the Kingfisher plotter files and can also be viewed on the map page of this website.

Sekian post tentang subsea pipelines ini, kenapa saya hanya membahas tentang 3 point (metode laying pipeline, free span, dan pipe crossing)?? karena memang post ini dibuat untuk memenuhi salah satu tugas saja :p

sebenarnya ada banyak sekali scope tentang desain pipeline ini, tetapi untuk saat ini saya memang hanya memilih untuk membahas 3 topik di atas. saja >.< Semoga post ini bisa membantu, mohon maaf bila ada kesalahan karena post ini dibuat terbatas pengetahuan saya (dan juga ditambah bantuan dari mbah google tentunya).

Last but not least, semoga post ini bisa memberikan nilai A untuk kuliah saya :) (amin amin amin amin amin amin) #neverendingamin

Good bye, partner

Good bye, partner

I should tell you that i’m actually allergic to animals fur, but honestly i can’t stand to not loving cats and having one as a beloved pet. And so, i started to have cats as my pet for years ago. And i will tell a story of one of them

This one name’s cappu, she’s been my pet since she was merely one month old. Someone gave her to my driver, and then my driver took her to my house.

the first time we met, which was 2.5 years ago, she was soooooo tiny, just as big as my hand is. And for a kitten like her, i may say that she was quite….. cocky.

She will bite or scratch my hands whenever i touch her. And she will go away whenever i approach her. I thought it was normal because she was newly brought to my house. But then i realized that it’s getting abnormal when 2 months later she still acts like that. Yeah, she’s definitely very cocky. But by considering her cuteness, i’m still willing to keep her as a pet.

Time flies by, and i can tell that she grows very fast. And finally, after 6 months having those ‘don’t even think to touch because i will bite you if you did’ moments, i finally can touch her as easy as a master touches her pet should be. But at the end, i can only touch and pat her head because she will bites if i touch else parts.

even though she behaves like that, i still love her for her cuteness and her loyalty.

She somehow always accompanies me, especially when i intended to do fasting but was too scared to have ‘sahur’ alone on the night. She will suddenly appears and then lays beside me when i’m having my ‘sahur’ until i finish it.

she somehow always welcomes me in the entrance stairs whenever i came home.

she somehow always knows that when my allergic becomes quite disturbing, she has to go away. So that my allergic won’t be worse.

she somehow always allows me to cuddle her when i’m sad to cheer me up

Before i write the next paragraphs, i confess that i’m a bad master for not being able to protect her after everything that she did to me.

2.5 years pass by like that and finally on a night, i woke up because i heard wild dogs barking in front of my house.

I opened my window’s curtain to see what happened and then i saw cappu, surrounded by 6 wild dogs and then she got bitten by them. I saw those moment with my own eyes, and i’m shocked.

I asked my driver to save her but it was too late.

it happened at 3 am and there’s no veterinarian is available to give her treatment. I can’t give it either because i did’t see any wound on her (while i know that she’s definitely badly injured) and she will bites anyone near her because she’s still shocked after the previous attacks.

All i can do was wait (and cry), i didn’t have any guts to see her hurt like that, and finally at 8am the veterinarian came to my house. But it was already late, because my driver told me that she has passed away. And i still didn’t have any guts to see her, even after she passed away.

I don’t want to remember her as a dead injured cat.

I want to remember her as a lovely cat who always accompanies me and somehow is able to cheer me up  when i’m sad.

by writing our memories in here, i hope everyone will acknowledge you as the best cat i’ve ever had. You are amazing, and i still love you

If cats can go to heaven, i’m sure that she would be there. Because she was a good fellow of mine.

i’m so sorry for not being able to protect you cappu :(  Thank you for the happy moments you gave to me and everything.

Good bye, my dearest partner. You mean alot to me

hello world

hello world

been writing (very) less on this blog. Now i guess i would like to start over again.

Hello to the reader-less place where i can dash off myself from the ‘real’ world and dump myself in this comfort zone. Yeah, i’m saying hello to my own world, i’m back! :)

it’s nearly 1:30 AM right now, and i have nothing to do except staring at my friggin laptop screen while lying on the bed. Such an important task, eh?

Well, i’m sure have a lot to tell in here (really, there’s a lot of thing happened in one month while i’m missing) but i’m surely can’t tell it with my current state (super duper ultra mega sleepy).  This may sound stupid, but with the least consciousness that’s left, i’m willing to write this because i want to practice my grammar. So.. i guess there’s nothing could go wrong with me doing a little writing thingy before go to bed.

Now, my wish before i go to sleep: i hope tomorrow (14th November 2011) will be a better day. Got tons of thing to do with so little time. I hope i can make the day. And live it happily. And… happy 23rd monthly anniversary for my dearest monkey :*

Instax Camera, a pleasure of vintage photography

Instax Camera, a pleasure of vintage photography

Mungkin masih ada yang belum tau instax camera itu apa. Instax camera adalah kamera yang langsung ngeluarin kertas hasil foto beberapa saat setelah memotret *mau nulis moto tapi rasanya agak gak sreg kalo ditulis. Yah kaya kamera-kamera jadul aja sih jatohnya. Gw masih inget dulu di serial mr. bean juga ada adegan dimana beliau lagi usaha motret berdua sama penjaga di inggris (itu loh, penjaga yang pake topi tinggi berbulu warna hitam, baju merah, bawa senjata, yah you know lah kaya gimana)

Sebenernya, gw gak tau kamera yang dipake sama mr. bean ini apaan, entah ini polaroid atau instax. Tapi kayanya sih polaroid, karena jaman dulu belom ada yang namanya instax. Nama instax camera ini baru ada setelah fuji ngeluarin fuji instax (kalo gak salah). Dan sebenernya lagi, gw juga gak tau apakah polaroid dan instax itu sama atau nggak, untuk sekarang, mari kita anggap sama aja yah. Hehe :p

Kenapa gw ngebahas tentang instax camera di sini? Lagi pengen aja, soalnya dari kemaren entah kenapa pokonya gw sering banget ngeliat instax dimana-mana, which means instax camera ini sudah mulai membooming di indonesia (walaupun sebooming-boomingnya instax camera tetep gak bakal ngalahin boomingnya blackberry). So, akhirnya gw kepikiran buat ngebahas tentang instax camera ini supaya orang-orang yang baca jadi tertarik pake instax camera dan blackberry kalah ngetrend *berasa banyak yang baca aja dah*

Instax camera yang paling terkenal di masyarakat adalah fuji instax mini 7s

Imo, mungkin alasan kenapa orang-orang beli fuji instax mini 7s ini sebagai instax camera pertama mereka adalah karena harganya paling murah. Dan juga karena ukurannya yang mini, kamera yang satu ini praktis banget buat dibawa. Harga refill kertas buat kamera ini juga paling murah dan bervariasi, aksesorisnya juga gampang dicari. Pokonya emang kamera ini cocok banget buat newbie :D

Hasil fotonya juga lumayan bagus (menurut gw)

Ada juga tipe lain dari instax mini, yaitu 25s dan 50s. Masing-masing tipe punya kelebihan dan kekurangan tersendiri, tinggal pilih sesuai seleran dan budget aja :D

Sekarang gw juga punya 1 instax camera *kaya mau beli lagi aja*. Kenapa gw tertarik sama instax camera? Karena hasil fotonya vintage banget, dan gw suka banget sama yang namanya vintage. Apalagi gw ini gaptek banget gak bisa ngedit foto, alhasil karena gak bisa bikin yang vintage sendiri jadinya beli aja deh yang langsung jadi vintage pas keluar jepret. Sedangkan buat gw sendiri prefer ke instax wide 210. Kenapa? Karena gw ngerasa kalo instax mini terlalu mini hasilnya dan alhasil kalo dipajang jadinya gak terlalu keliatan (padahal emang mata gw aja kali ye yang rabun). Tapi ya kalo masalah harga, emang refill wide ini lebih mahal daripada yang mini, harga kameranya juga agak lebih mahal daripada yang mini (walopun masih lebih murah daripada 50s). Perbandingan hasil foto instax mini dan instax wide tuh kaya di bawah ini

Dan juga, instax wide 210 punya fitur-fitur yang (menurut gw) helpful banget. Fokus kamera ini bisa diatur, flash-nya juga bisa on/off, dan yang paling penting…. ada fitur lighten normal darken buat hasil jepretannya. Maksudnya, kalo misal gw pilih mode lighten, alhasil jepretan dari kamera ini jadi lebih terang, dan seterusnya. Sampe sekarang, gw udah nyoba mode lighten dan normal (gak mau pake yang darken, emang siapa juga sih yang mau keliatan lebih item di fotonya?), dan hasilnya bagus-bagus aja tuh. Makanya gw masih betah sampe sekarang pake instax wide ini :3

Dan inilah beberapa hasil jepretan instax wide tercintah

Eh tapi, ada juga 1 hal yang bikin gw gak puas sama kamera instax wide punya gw ini.

Ini kamera pasti tauuuuu aja kapan gw bikin dosa dan kapan nggak* (*baca: narsis). Iya, tiap kali gw mencoba foto sendiri pasti hasilnya jelek (terlihat di foto terakhir). Sampe sekarang gw udah mencoba 2x berbuat dosa* (*baca: foto narsis sendiri) dan hasilnya jelek dua-duanya. Entah emang narsis itu beneran dosa ato emang gw yang jelek. Tapi kalo ngeliat foto yang bareng sama orang lain asa bagus-bagus aja sih. Mungkin narsis itu emang dosa, apalagi sendirian #ngacomaksimal

Oh well, just enjoy the pleasure of its vintageous shot :D

*anw, gambar-gambar yang ada di post semuanya hasil googling kecuali foto yang ada gw-nya :p*

Teknik Kelautan ITB, what is it really about?

Teknik Kelautan ITB, what is it really about?

Teknik kelautan itb, jurusan yang gw tekuni di kampus ITB. Merupakan salah satu bagian dari FTSL (Fakultas Teknik Sipil dan Lingkungan). Mungkin orang-orang masih ngira kalo di teknik kelautan ini cuman belajar tentang kapal, laut, ikan, dll. Dimana sebenarnya menurut gw main concern dari teknik kelautan itb sama sekali gak ada yang mengarah ke sana. Di teknik kelautan juga sebenernya ada kuliah tentang kapal dan ikan, tapi itu semua adalah mata kuliah pilihan (gak harus diambil kalo gak minat). Jadi biar orang-orang gak salah paham sama jurusan gw yang satu ini, akhirnya gw memutuskan untuk bikin post ke-3 tentang jurusan tercinta ;3

Teknik kelautan sebenernya dulu adalah pecahan dari teknik sipil. So, udah jelas bahwa di teknik kelautan ini sebenernya juga mempelajari struktur. Teknik sipil dan teknik kelautan sama-sama bikin konstruksi struktur bangun, perbedaan paling utama dari 2 jurusan ini adalah lahan bidangnya, dimana teknik sipil lahannya di darat dan teknik kelautan lahannya di daerah laut (pantai juga termasuk).

Bisa dibilang kalau teknik kelautan itu (mestinya) lebih susah daripada teknik sipil karena keadaan alam di laut jauh lebih ganas daripada di darat (ex: gelombang laut, angin, suhu), jadi struktur yang dibangun di kawasan laut ini jelas harus lebih kuat daripada yang ada di darat. Otomatis teori yang digunakan untuk analisis struktur bangunan laut ini jauh lebih complicated. Tapi imo, semua itu worth it kalo dibandingkan dengan hasil yang didapat.

Karena imo, salah satu advantage dari teknik kelautan ini adalah lahan yang tersedia masih banyak banget dan ilmu teknik kelautan ini sedang berkembang. Secara, indonesia 70% terdiri dari lautan dan belum semua dari lahan lautan ini sudah dimanfaatkan oleh bangsa kita. Banyak banget bangunan yang bisa didesain dengan mengaplikasikan ilmu teknik kelautan ini, contohnya pelabuhan, jembatan (jembatan selat sunda termasuk salah satu proyek dosen teknik kelautan btw), breakwater, platform, subsea, pulau buatan, dermaga, dan juga bangunan pelindung pantai lainnya yang banyak banget jenis-jenisnya. Kalo menurut gw, yang paling menarik adalah platform dan breakwater.

Breakwater

Buat orang-orang yang sering pergi ke pantai-pantai, pastinya pernah ngeliat semacem tumpukan batu di daerah pantai atau di bagian agak ke tengah laut. Nah, itu dia yang namanya breakwater :D

*semua gambar diambil dari hasil googling :p*

Dari namanya, udah jelas kalo breakwater ini gunanya buat mecahin gelombang. Biasa dipake buat melindungi pantai dari gelombang atau bisa juga buat melindungi jalur pelabuhan (supaya gelombang yang ada di jalur pelabuhan lebih tenang dan kapal yang lewat sana gak gampang oleng). Di contoh gambar atas bisa diliat kalo breakwater itu terdiri dari banyak lapisan, dan lapisan yang paling luar dari breakwater ini biasa disebut armor layer. Kenapa disebut armor layer? Karena isinya emang armor yang berperan penting sebagai pemecah gelombang. Armor untuk breakwater pun bermacem-macem, tapi armor yang paling in sekarang adalah x-block (ada istilah lain buat x-block ini di teknik kelautan, tapi….. gw lupa #anakKLdurhaka). X-block ini efektif banget buat mereduksi efek destruktif gelombang karena dia menggunakan sistem interlock (kalo gak salah, agak lupa namanya lock apaan… #anakKLdurhakalagi) dimana kalo x-block ini diletakkan dengan teratur dan saling ‘mengunci’ maka keefektifan x-block untuk mereduksi efek destruktif gelombang akan lebih besar.

Sekarang, jumlah breakwater di indonesia masih belum terlalu banyak, sedangkan pantai-pantai di indonesia yang membutuhkan breakwater ini bisa dibilang masih banyak. Bayangkan kalo semua pantai-pantai di indonesia yang jumlahnya banyak ini bisa dimanfaatkan dengan baik, mungkin indonesia juga bisa jadi tempat pelabuhan internasional yang beken kaya singapur *amin*. But first, kalo mau bikin pelabuhan atau mungkin bikin hotel di pinggir pantai buat bisnis… ya bikin dulu dong breakwaternya biar gelombangnya jinak dan semua yang kalian bikin di pantai terlindungi *ting*

Platform

Mungkin kalian pernah ngeliat bangunan-bangunan semacam ini di dokumenter atau film-film

Ya, pasti kalian tau bahwa bangunan ini gunanya buat pengeboran minyak di laut, tapi kebanyakan orang gak tau nama bangunan ini apa. Well, inilah yang namanya platform. Seperti yang sudah gw jelaskan, platform ini adalah struktur, cara perhitungannya hampir mirip dengan cara perhitungan untuk desain bangunan biasa, tapi bedanya adalah struktur platform ini ada di lingkungan laut, which means ada faktor tambahan seperti gaya gelombang yang harus dimasukkan ke dalam perhitungan. Which also means, itungannya sedikit lebit ribet. But worth it juga kalo dibandingin dengan gajinya :9

Bisa dibilang platform ini adalah salah satu sumber proyek berduit banyak di Teknik Kelautan, karena di indonesia ini masih banyak sumber minyak yang belum terjamah dan diolah, sedangkan ilmu yang digunakan di bidang ini cuma diajarkan di teknik kelautan.

Masih banyak juga proyek-proyek menarik dari Teknik Kelautan, contohnya piping (pipa bawah laut), subsea structure, dan…..  pulau buatan, bidang yang hasilnya paling eye catching sedunia —-> Palm Island di Dubai

Kalo lulusan teknik kelautan kerjanya harus di laut ga? Gak harus, bisa juga kok kerja di darat. Bahkan semua bangunan offshore (offshore tuh maksudnya bangunan yang ada laut, bukan pantai ya) sebenernya dibikin (atau istilah tekniknya –> fabrikasi) di daratan dulu. Kalo udah selesei difabrikasi, baru deh dibawa ke tengah laut. Jadi sebenernya, sarjana teknik kelautan itu kerjanya di darat juga. Tapi mungkin ada juga yang ikut proses instalasi di tengah laut, jadi ya terpaksa ikut ke tengah laut. But you’re free to choose where to work, right? Jadi para calon sarjana teknik kelautan bergender wanita (termasuk gw juga), gak usah takut harus kerja di laut, karena emang gak harus kok, impian kita untuk menjadi pegawai eksekutif kantoran yang cantik dan sukses masih bisa dicapai :)

Sekian tulisan gw tentang teknik kelautan ini, post ini ditulis mostly berdasarkan opini dan pengetahuan yang telah gw pelajari selama ini (jadi maap kalo ada yang salah nulis)
