Lagunya bisa membuat semangat, jadi di hapalin aj..ini lagu dari film Hannah Montana..ada quote baru dari film itu..”life is a climb, it’s hard but the view is great,so keep going”..Ini lagunya

I can almost see it
That dream I am dreaming
But there’s a voice inside my head saying
“You’ll never reach it”

Every step I’m taking
Every move I make feels
Lost with no direction
My faith is shaking

But I gotta keep trying
Gotta keep my head held high

There’s always gonna be another mountain
I’m always gonna wanna make it move
Always gonna be a uphill battle
Sometimes I’m gonna have to lose

Design Study of Gas Cooled Fast Reactor with Helium as Coolant and Natural Uranium as Fuel Cycle

Abstract

Gas Cooled Fast Reactor (GFR) is one of six selected of IV generation reactor. GFR has Brayton fuel cycle, uses fast neutron and operates in the high temperature (850˚C).This condition has benefit to produce hydrogen. As we know that hydrogen is the one of promising energy because it cannot produces CO₂, CO, SO₂ and global warming. GFR has high safety, proliferation resistant and economical. In this case, we will burn natural uranium (U-238) for 60 years and put them in 6 regions which have same volume. Hence, in the next 10 year, GFR produce plutonium and this plutonium will be moved from first region to the second region, the fuel from second region is moved to the third region etc. In this experiment, we use GFR with 2400 MWth, Helium as coolant and Stainless Steel 316 (SS316) as cladding. In this research, we did simulation with SRAC, a code developed by the Japan Atomic Energy Research Institute (JAERI), to know about neutron design, thermal hydraulic of GFR. The thermal hydraulics is able to calculate in-core temperature distribution, coolant density profile, coolant mass flow and flow rate, and also coolant pressure drop after passing through the core.

Keywords: GFR, helium, pin

Always be My Baby  by David Cook

We were as one babe
For a moment in time
And it seemed everlasting
That you would always be mine

Now you want to be free
So I’m letting you fly
Cause I know in my heart babe
Our love will never die
No!

Perbankan Islami MB – 4034 adalah kuliah yang telah saya ambil dari program studi Sekolah Bisnis dan Manajemen (SBM – ITB). Terima kasih kepada bapak Arson dan Pak Iwan yang telah menjalankan tugasnya sebagai dosen dengan baik. Terima Kasih, Pak, berkat belajar Perbankan Islami, saya jadi tau dan bisa menjawab semua pertanyaan – pertanyaan yang mengaduh pikiran saya selama ini. ‘Apa benar kerja di Bank haram, bagaimana hukum riba dalam perbankan dan apa perbedaan bank syariah dengan bank konvensional spt BCA, Mandiri, BNI dll?’.Saya juga sudah sedikit mengerti dalam mengartikan kata-kata dalam bahasa Arab dan terima kasih juga karena telah mengingatkan saya untuk tidak menjadi PENGIKUT agama saja.’Kita tidak boleh taklik  kepada fatwa2 tapi kita harus memikirkan pertanyaan ‘Kenapa disuruh begini dan kenapa dilarang begitu oleh sang Pencipta’..Thanks a lot..Semoga ilmu yang telah Bapak berikan dapat menjadi amal ibadah di akhirat kelak..Amin :D Berikut inti sari dari apa yang telah saya pelajari selama satu semester. Semoga bermanfaat

ga tau deh, bener bisa ga ya, semester ini bakal jadi semester terakhir di ITB? Yes, I hope this semester will end soon, I can’t help waiting any longer

Dah capek belajar di kelas, ngerjain PR, UTS yg stres pastinya dsb, mo nyari suasana kerja, dimana disitu ada bos, ada partner kerja, ada deadline kerja,ada lembur, ada waktu gajian tentunya

Semester ini cuman ngambil 14 sks, padahal seharusnya 17 sks, tetapi karena gara-gara jadwal kuliah Bisnis Berbasis Teknologi(kuliah pilihan di SBM) dirubah jadwalnya secara mendadak…dan bodohnya saya baru tau itu setelah PRS…Damn it !!!!…. Jadwal itu bentrok dengan kuliah rekayasa lingkungan (ini matakuliah wajib)…

So..I have 17 sks dan diakhir semester ini bakal ada nilai E ditranskrip nilai ..WHAT A STUPID MISTAKE

Never mind, ..Let’s forget it

Klo taun pertama kuliah di ITB:

Lagi ga ada kerjaan..tus kepikiran tuk ngubek2 blog si Kris…kmren dia nanya2 blog awa..yowis tak kunjung balik aj..tus dapet saran ngecek ini…MindMedia.

Mantap bro, sama kek personalitya awa yg sebenernya…Ga sia2 kuliah di Fisika, ternyata awa dianjurkan jadi scientist Awa visual, klo belajar apa aj, musti baca sendiri, klo diterangin sm orang laen, ndak mudeng awa..Two thumbs up lah….Please check it out

Meri, you are somewhat left-hemisphere dominant and show a preference for visual learning, although not extreme in either characteristic. You probably tend to do most things in moderation, but not always.

Your left-hemisphere dominance implies that your learning style is organized and structured, detail oriented and logical. Your visual preference, though, has you seeking stimulation and multiple data. Such an outlook can overwhelm structure and logic and create an almost continuous state of uncertainty and agitation. You may well suffer a feeling of continually trying to “catch up” with yourself.

Your tendency to be organized and logical and attend to details is reasonably well-established which should afford you success regardless of your chosen field of endeavor. You can “size up” situations and take in information rapidly. However, you must then subject that data to being classified and organized which causes you to “lose touch” with the immediacy of the problem.

Your logical and methodical nature hamper you in this regard though in the long run it may work to your advantage since you “learn from experience” and can go through the process more rapidly on subsequent occasions.

You remain predominantly functional in your orientation and practical. Abstraction and theory are secondary to application. In keeping with this, you focus on details until they manifest themselves in a unique pattern and only then work with the “larger whole.”

With regards to your career choices, you have a mentality that would be good as a scientist, coach, athlete, design consultant, or an engineering technician. You can “see where you want to go” and even be able to “tell yourself,” but find that you are “fighting yourself” at the darndest times.

Your Brain Usage Profile:

Auditory : 40%
Visual : 60%
Left : 57%
Right : 42%

No matter which side of your brain is dominant,
M i n d W a r e
can strengthen your emotional brain power by helping you understand how
you feel about yourself.

30 Oktober 2008 adalah hari yang paling bersejarah buat adik saya. Kemaren dia operasi usus buntu kronis.
