MIT adds one more feather to its cap . Most of you must have heard or seen about BAJA . Read on to know the complete thing . Two of my friends ( Abhishek , Abhinav ) are in the team of BAJA Manipal .

Their Tagline :

BAJA MANIPAL - The official team representing MIT , Manipal at Mini BAJA  Competition

organised by SAE( Soceity of Automotive Engineers )to be held in South Africa in

October 2009 in Pretoria University , Pretoria .

ATV

As mentioned above , they are the official team representing MIT . Many prestigious colleges like the IIT’s and DCE have their own teams .Last year , Formula Manipal represented MIT at FSAE , Italy where they finished 27th.

BAJA Competition is basically a platform where teams have race their ATV’s ( All Terrain Vehicles ) .

Their sponsors range from Pepe Jeans , Snack Shack , Riverdale , Dollops , BIG 92.7 FM to various MIT Alumni .

The shipping cost to SA is borne by MultiLine Circuits and ALF Engineering Pvt Ltd is providing the technical support .

The whole ATV is being currently built at Nasik , Maharashtra . The ATV will be brought to MIT before being shipped to SA .

MIT has once again proved that its “the” best in Mechanical Engineering

To begin: news of the rotor.  When we found out last week that our rotor was not qualified for our gondola’s weight this flight, we returned it to Berkeley for a “pull test.” As the name suggests, the test consisted of gripping the rotor from both ends in a machine and pulling–with 50,000 pounds of force!  Yesterday, we learned that the rotor had passed the test without any catastrophic failure, so we can fly without cutting weight.  However, the yokes and pins we use to connect the rotor to the balloon above and the gondola below were bent during the test.  Accordingly, Berkeley is making new yokes and ordering new pins.  Hopefully the rotor will return to us very soon!

Update, 4/30:  A closer inspection of the rotor in Berkeley found a cracked component.  This is going to impose a significant delay…

As we wait, we’re dealing with lots of odds and ends.  On Monday, we got the flight computer interfaced with CSBF’s commanding computers (on the first try!).    Daniel has been heroically taping temperature sensors all over the gondola.  Alan and I are continuing to debug the flight computer and ground control program.  Justin is working on our analysis software.  Zhong-Kai is keeping track of the card cages.  And Mark is talking to all the CSBF personnel and keeping us on track.

Today the wind was a bit lighter, so we attached the solar panels and pushed the gondola outside (waaaaay outside) to test the solar power system and to calibrate our differential GPS.  Both systems performed flawlessly!

NCT goes outside.

Our other task has been to calibrate the efficiency of the telescope.  We do this by placing radioactive sources in the field of view of the instrument.  These sources emit gamma-ray photons of specific, known energies.  Since we know the activity of the sources–the number of photons they emit per second–by placing them at a specified distance and counting how many photons we observe, we can calibrate the efficiency of our telescope.  (This is called the “effective area” of the telescope; its maximum is the geometric area of the detectors, which would happen if all photons hitting the detectors were observed.)

Since the efficiency varies with energy and throughout the field of view, we have quite a few calibration measurements to take.  We need fairly precise knowledge (~ a few centimeters) of the position of the source relative to the detector for these calibrations, which is hard since the source is several meters in the air!  To find the positions, we use a theodolite–a surveying instrument which measures angles.  The last few days, I’ve been training the other students to use the theodolite, and we’re all taking turns doing late shifts to take data.

Our calibration setup. The theodolite is in the foreground, and the source is on the aluminum board overhead.

The latest CSBF weather reports indicate that turnaround–the period when the upper atmosphere winds are still enough for long flights–is still about a week and a half away.  There’s some definite jockeying for position in the flight queue happening–come on, rotor!

Hot Dip Galvanizing adalah proses pelapisan iron atau steel dengan lapisan zink.

Proses HDG dibagi menjadi 3, yaitu :

1. Surface preparation
Ikatan metalurgi Zink dan Iron hanya dapat terjadi bila permukaan steel bersih, oleh karena itu perlu dilakukan persiapan permukaan dengan cara :
a. Degreasing, untuk membersihkan kotoran, minyak maupun organic residue
b. Pickling, membersihkan mill scale dan oxide
c. Fluxing, mild creaning dan provide protective layer

2. Galvanizing
Steel dicelupkan pada molten zink yang terdiri dari 98% pure zink, dan 2% element lainnya untuk coating properties (Al, Bi, Ni). Zink akan bereaksi dengan Iron dan membentuk galvanized coating.

3. Inspection
Dilakukan untuk memastikan kesesuaian dengan spec yang ditentukan. Surface defect dapat diketahui hanya dengan visual inspection dan coating thickness diukur dengan magnetic thickness gauge.

Environmental Performance :
- Atmospheric
- Liquid
- Soil
- High temperature
- Low temperature
- Concrete

Keuntungan HDG :
1. Bebas maintenance 50 - 100 tahun pada atmospheric environment
2. Long term maintenance pada soil, water dan chemical environment
3. Tidak perlu touch up
4. High & Low temperature performance
5. 100% recyclable

Sulfide Stress Corrosion Cracking atau biasanya disingkat SSC atau SSCC adalah kegagalan yang terjadi pada metal karena reaksi bersamaan antara stress dengan hidrogen yang berasal dari H2S.

Parameter terjadinya SSC :

- Konsentrasi H2S 50 ppm, namun untuk daerah welding bisa <50 ppm

- Tekanan Parsial >0,05 Psia

- PH kurang <7

- Temperatur operasi antara 38 - 150 deg C tp paling banyak terjadi pada suhu 65 - 95 deg C

Mekanisme terjadinya SSC dimulai dengan berdifusinya atom hidrogen yang berasal dari H2S ke dalam base metal. Atom atom ini kemudian membentuk H2 yang mengakibatkan getasnya struktur kristal. Pada saat konsentrasi hidrogen mencapai titik kritis dan adanya stress maka SSC akan terjadi.

Jadi H2S sebenarnya tidak berpartisipasi secara aktif dalam terjadinya SSC tetapi H2S yang menghasilkan hidrogen yang kemudian berdifusi ke dalam base metal.

Type SSC :

- Intergranular, crack akan dimulai dan berkembang di sepanjang batas butir.

- Transgranular, crack akan terjadi melintasi butir.

Metoda pengendalian korosi ada 5, yaitu :

1. Pemilihan Material

jenis material yang digunakan harus memiliki ketahanan korosi yang tinggi di suatu media tertentu sesuai dengan lingkungan tempat aplikasinya.

2. Proteksi Katodik

Proteksi katodik ada dua macam yaitu :

a. Impressed current, struktur yang dilindung mendapat supply elektron sehingga potensialnya menjadi lebih katodik. Arus yang digunakan adalah arus searah, dmana arus negatif dihubungkan dengan logam yang dilindungi sedang arus positif dihubungkan dengan anoda pembantu.

b. Anoda Korban, menggunakan prinsip galvanik dimana struktur yang dilindungi dihubungkan dengan logam lain yang bersifat anodik.

3. Inhibitor

Penambahan zat kimia dengan konsentrasi rendah ke media lingkungan untuk memperlambat laju korosi logam.

4. Proteksi Anodik

Umumnya dilakukan pada logam yang bersifat pasif . Lapisan pasif akan dipertebal dengan memberikan potensial ke arah anodik.

5. Coating

Permukaan logam dilapisi dengan bahan logam maupun non logam yang terdiri dari campuran senyawa kimia untuk mencegan kontak langsung antara logam yang dilindungi dengan lingkungan.

The day kicked off as a usual day with me getting up a bit late (8.15am… class had to start at 9). I have become quite used to all this now. Getting up 45 minutes before the class was actually quite good as compared to the days before. So i got ready well in time and reached the college. Attended the last Thermo class of the semester, second last class of M.Design. A boring lecture of DOM. DOM is a very interesting subject and i have got my best internals in the same subject ( 49 ). But the topic was quite boring and i was not doing anything except merely copying the solution of the problems done in the class. When back from the college, i had the usual kind of lunch at the AKSHAYA MESS. After that headed back to the room. Took CRIMSON SKIES ( a fighter aircraft kind of game which i am yet to play) from Devraj. Just transferred it to my laptop and then set off to clean the huge load of undergarments… I also had my CAD lab end-sem from 3.30pm for which i never felt like studying. But coz it was the end-sem, i looked over a few commands and went for the exam. While i was heading to the hostel gate, i met Ashish and coz there was no one else with him, he gave me a ride to the college. This saved me that sweaty walk to the college at 3pm. . When i reached the CAD lab, the previous batch were still doing their exam and this made us all wonder about the difficulty of the exam we had ahead of us. The first to come out was Mehul (Roll#101). We asked him about the test. He said it was easy though he did not complete it. More and more people came out of the lab and all had the same experience – Easy but could not complete. The only one who could complete was Anirudh Raut (Mech Topper). Ya, he always does it. K. So this was getting difficult. Only 1 guy finishing the question and that too at the last moment wasn’t very encouraging. But yes, it kind of prepared me for the test. As soon as we entered the lab and when we were assigned our computers, we immediately ran the customary check on the software to be sure if it was working fine. Mine was working fine, but the mouse was a pretty old one and was a bit bulky one, so i wasn’t very comfortable with it. But i decided to go on with it. I had the question in my hand. And the question seemed a bit difficult. But it was so only for a few moments. 10 mins later, i was done with the top view, another 10 mins and i was done with the front view and a few minutes later, the side view was done. i made some minor adjustments to the drawing, labelled it and called out for evaluation. i guess everyone in the room was shocked to know that i had completed the drawing in 30 mins straight of the allotted 90 mins. i was surprised myself, but this was something good. So i just checked my drawing internal marks. And thus i got to know that i had secured the full 10 marks for this test. . So Mr. Vijay. G.S. told me my internals (63.42/70) which were not very good ( as compared to the previous years… coz i had got 50/50 in the 1st semester and 59/60 in the 3rd semester. And each of those times i had got an A+ in the subject…). This time the chances of A+ looked bleak. . Well whatever… IEEE has its GBM (organised by us) at 5pm and i felt i might be asked to speak, so i was gathering some points to speak in case i was called to the dais. So i talked to Mr. Kamath and got a list of software installed in the lab which might be of good use. I set off for the LA (Library Auditorium) but i met Raka (Anirudh Raut) and Manan on the way so instead of reaching the LA, we ended up in the Canteen eating Grilled cheese sandwiches and having my second glass of Cold coffee for the day. And coz it was already over 5pm, i decided to finally go off for the GBM. When i reached i was quite surprised that it was going to start soon. And it did! The GBM took off at around 5.15pm and we were over with the major part of talking by 5.30pm (which also comprised of the announcement of the new board.)

As Rahul NS announced the exe-com board, i was bit shaken when he announced my name in the Logistics team to be headed by Prasanna. i thought that the seniors had slashed the idea of mechanical society coz of my failure to submit the report in time. But soon after Rahul NS also announced that IEEE was diversifying by introducing the Mechanical Society to be headed by me. That sounded nice. Really. I stood up once again for everyone to see that it was me who would be leading it…

Soon they began with the distribution of the certificates. Grabbing the opportunity, even i reached out for my certificates. Though i discovered something strange. I had also got a TESARACT tech talk certificate even though i had not attended any of its lectures. . Next i collected the IEEE membership cards for digvijay, devraj and myself, also a few free to take Spectrums and also the ones issued to digvijay and devraj. Took them off and then left the LA with Sean (The GBM was wrapped up by then). Sean was grateful enough to give me a ride to KC ( Kamath Circle). After which i walked back to the hostel. On the way i met Jayant and Srestang (Mech 1st years) who congratulated me and asked for some guidance on the Mechanical branch. Briefed them a bit and then i went back to the hostel. Gave Devraj his stuff. And headed for Dinner in the mess with Tushar Mishra. It was Tuesday and thus we had CHHOLE-POORi in the dinner… Had the dinner, then bought 4 bananas (Rs.10) and then headed back to the room. Had been quite a nice day and did not have college for the next 4 days. (2 days for election duty and May1- May Day). Plus it was Barca-Chelsea 1st Leg of Champions League that night (at around 1am)… So just felt like putting it down here… and here it is… Looking for more good moments ( might be boring for the reader )

Dunia di abad 21 bukan lagi sebuah entitas yang terpisah-pisah. Teknologi di bidang informasi dan telekomunikasi telah menciutkannya menjadi sebuah desa global (global village). Seseorang kini bisa mengetahui dengan cepat apa yang terjadi di belahan dunia lain. Tidak lagi aneh jika seseorang kini bisa bekerja di Amerika, minum teh di Inggris dan makan malam di Perancis. Sebagai orang yang tinggal di negeri Tropis dengan dua musim ingin pula sekali-kali merasakan dinginnya salju dan musim salju. Tinggal di luar negeri dan meraih tiket ke pergaulan internasional kini bukan lagi khayalan bagi kita yang berduit pas-pasan. Beragam jalan membentang menunggu ditapaki. Salah satunya adalah melalui program beasiswa. Salah satu yang cukup dikenal olah pelajar Indonesia adalah beasiswa dari negeri Kincir Angin, Belanda. Memiliki pengalaman semacam Andrea Hirata dalam novel Edensor-nya kini bisa kita rintis jalannya dengan mencari informasi lebih banyak tentang beasiswa yang ternyata bertebaran di dunia maya. BEASISWA BELANDA Salah satu beasiswa yang diminati adalah beasiswa dari Belanda. Negara ini banyak dipilih karena memiliki kedekatan sejarah dengan kita. Selain itu banyak kuliah memakai pengantar bahasa Inggris, sehingga memudahkan proses belajar. Uraian lebih lanjut mengenai beasiswa di belanda berdasar kategori : > Jenis : Master, non gelar > Nama Program Beasiswa HSP huygens : - 10 % top ten student - <2 tahun - max 35 tahun - euro 900/month, tuition, visa, travel NFP (national fellowship program), dengan persyaratan : - due date februari - ditujukan untuk mid career proffesional - kuota 10 orang/tahun - jenisnya ada master, course dan Ph.D - motivational letter StuNed : - 100 - 200 orang/tahun - 57 negara - 2 tahun bekerja di institusi yang sesuai dengan bidang ilmu jenjang pendidikan sebelumnya - dosen, PNS, aktivis LSM, wartawan dan non multinational company - ITP 550, IELTS 6 - mendaftar dulu di university tujuan baru kemudian STUNED - max. usia 40 tahun - tuition euro 800/month - deadline 15 maret > Persyaratan Umum : - Deadline : Maret/april - Requirement : - WNI, 40 tahun (pria) dan 45 tahun (wanita) - Masa kerja 2 tahun, sesuai bidang ilmu - Surat penerimaan dari university - TOEFL ITP 550/IELTS 6/ CBT 213 - Essay - Motivation letter - Proposal riset - Surat Rekomendasi dari dosen pembimbing - International CV - transcript - certificate - Surat jaminan dari atasan bahwa sekembali dari beasiswa akan bekerja lagi di institusi asal > Universitas : Universitas di Belanda ada yang research university dan juga applied knowledge. Berikut ini list universitas di Belanda : * Universitas Erasmus Rotterdam * Universitas Radboud Nijmegen * Universitas Terbuka * Universitas Kerajaan Groningen * Universitas Teknik Delft * Universitas Teknik Eindhoven * Universitas Amsterdam * Universitas Leiden * Universitas Maastricht bersama dengan Limburgs Universitair Centrum (B) menjadi Universitas Transnasional Limburg (tUL) * Universitas Nyenrode * Universitas Tilburg * Universitas Twente * Universitas Utrecht * Universitas Vrije - Amsterdam * Universitas Wageningen > Iklim di holland Sebagai antisipasi kita yang biasa hidup di iklim tropis, berikut adalah perkiraan suhu di Belanda. summer : 8 degree winter : 2 degree > Culture Shock Masalah yang kadang dihadapi oleh para pelajar Indonesia di Eropa adalah masalah gegar budaya atau culture shock. Adat istiadat yang berbeda kadang menimbulkan rasa tidak nyaman yang pada gilirannya mempengaruhi semangat belajar. Untungnya di Belanda sudah ada PPI (Persatuan Pelajar Indonesia), ada PPI (persatuan Pelajar Indonesia) antara lain : PPI Belanda PPI Wageningen PPI Groningen Semakin bersemangat melanglang buana dengan beasiswa? Tapi bingung juga menilik persyaratan yang bejibun? Kita bisa meminta informasi lebih dalam ke NESO (Netherland Education Supporting Office). Sebuah lembaga non profit yang membantu program beasiswa. Sering berkeliling ke kota-kota besar di education fair, ataupun di universitas-universitas besar. Kalau di Yogya, biasanya diselenggarakan di ballroom hotel Santika secara free.
