YSEP Tokyo Institute of Technology - Study on Japanese Companies and Industries: Hitachi-GE Nuclear Power Ltd

Company Visit Hitachi GE Nuclear Power Energy

Hitachi-GE Nuclear Ltd, was the last destination for Study on Japanese Companies and Industries. The study tour itself held at 23th November 2016, actually that date was national holiday. However,  I was very lucky since only 8 of SJCI students that could participate on this tour. The journey took about 3 hours, since the factory located in Hitachi city in Tochigi Prefecture. 

We arrived at Hitachi around 10.50 AM. First we were introduced to company profile. Hitachi-GE Nuclear Energy, Ltd., was established in 2007 by Hitachi, Ltd., and General Electric Co. of the U.S. as a means of participation in the nuclear energy business. Hitachi-GE Nuclear, Ltd., has participated in the construction of all of the nuclear power generation plants(ABWR) in Japan and provide high-quality products and services. Business outline of the company has five main contents

1. Design

Implement 3-D plant Computer-Aided Engineering for the improvement of operating efficiency and developed it into an integrated plant CAE system for the realization of higher quality plant design.

2. Manufacturing

Engage in the manufacture of nuclear power generation equipment offering the highest levels of safety and reliability.

3. Construction

Build plants by incorporating advanced methods, including large-slace module construction and block construction, to meet the need for streamlined construction and shorter work periods.

4. Maintenance

Incorporate the latest inspection, repair and preventive-maintenance practices in order to ensure services of the highest value.

5. Research and Development

Conduct research and development in the fields of nuclear power plants, nuclear fuel and the nuclear fuel cycle.

After having a lunch, we were going to Odaira memorial museum. The museum was about the founding father of Hitachi Ltd and scenery of the first workshop. The equipment for manufacturing itself still traditional. I was surprised that the first product of this company was a motor and some of the them were functioning. Then, we headed to Rinkai works and introduced how to manufacture the heavy component of the reactor. It took about 4-5 years to finished the manufacture of nuclear power plant, excluding licensing and designing process.

YSEP Tokyo Institute of Technology - Trip to Nikko

Trip to Nikko

Nikko, merupakan tempat wajib untuk menikmati autumn di Jepang. Untuk perjalanan ke Nikko, kita merencakan buat jalan tanggal 12 November 2016, pergi dan pulang di hari yang sama. Tetapi setelah melihat google maps, merancang itinerary dan melakukan banyak estimasi, 1 hari sangat tidak cukup dan tidak efisien. Kalaupun dipaksain 1 hari, nyampenya jam 10an dan pulang jam 5an. Akhirnya, setelah diskusi di grup kita ganti tanggalnya jadi 19-20 November 2016, jadinya 2 hari 1 malam. Person in charge buat perjalanan kali ini, shabrina akhirnya merombak ulang semua itinerary dan juga memesan penginapan.

Gw sampe aobadai eki 10 menit sebelum waktu janjian, andrew nyampenya 15 menit setelah janjian dan cewe-cewe entah gimana baru nyampe 30 menit setelah janjian :”) Akibatnya, kita ga dapet kereta yang 09.10 dan harus nunggu yang 10.40 wkwk. Untungnya perginya 2 hari jadi ga rugi berangkat telat. Sebenernya keretanya yang 9.30 juga ada, tapi ga kecover sama Nikko All Pass. Buat orang asing, kita bisa menikmati perjalanan ke Nikko dengan Nikko All Pass seharga 4520 untuk 4 hari 3 malam. Ada juga Nikko 2 Day pass dan pass buat ke tobu world square dan edo theme park. Jadi sebelum pergi ke Nikko, coba aja dulu googling “Nikko Pass” dan barulah buat itinerarynya. Kita milih pass yang 4 hari 3 malem karena itu ngecover biaya bis ke lake chuzenji, kalau yang 2 hari 1 malem ga kecover hehe.

Nikko All Pass

Untuk keretanya sendiri, tempat duduknya hadap-hadapan jadi nyaman buat ngobrol, makan dan bahkan ada yang main kartu. Pemandangan di jalannya sendiri juga berbeda, kalau biasanya di tokyo pemandangan keretanya itu gedung-gedung, di perjalanan ke Nikko itu bisa ngelihat sawah, hutan dan bukit. Keretanya juga ada penghangatnya, waktu berangkat kan hujan jadi sepatunya basah, gara-gara penghangat di kereta sepatunya sampe kering lagi. Eiya andrew kasian disini ketiban tas yang jatuh.

kereta aslinya bukan yang ini sih...

Sampe Tobu Nikko eki kira-kira jam 1 kurang. Stasiunnya ga begitu besar dan menurut gw agak tradisional. Diluar stasiun, ada terminal bis dan juga penginapan kita, Nikko Lodge Hotel. Letaknya emang deket banget sama stasiunnya, jadi ga perlu jalan jauh lagi. Kita pertama-tama makan siang dulu, bekal tentunya, di longue nya Nikko Lodge Hotel. Kita belum bisa masuk ke kamar karena jam check in nya itu baru jam 3. Jadinya kita nitip barang-barang kita dulu di longuenya.

Nikko Eki

Pemandangan di depan stasiun

Destinasi pertama kita adalah jembatan Shinkyo kebetulan karena lagi gerimis, pemandangan jembatannya lagi berkabut.

Shinkyo Bridge

World Heritage

 Lalu kita menuju ke arah toshogu shrine. Sepanjang jalan menuju kesana kita bisa ngelihat daun-daun musim gugur yang udah menguning dan memerah. Oiya kita sendiri ga masuk ke templenya karena selain biaya masuknya cukup mahal (1300 yen) jam bukanya juga tinggal 40 menit lagi. Disini andrew juga kasian lagi, kepleset di tangga L

Rencana berikutnya adalah pergi ke Onsen, tapi sebelumnya kita ke hotel dulu buat check in dan siapin barang bawaan untuk onsen. Pas di liftnya hotel, andrew ketabrak sama pintu lifnya #prayforandrew. Gw ampe ga ngerti kenapa temen gw yang ini kena sial mulu padahal baek banget.

 Tempat onsennya sendiri ada di daerah Kinugawa dan buat kesana kita perlu naik kereta dari stasiun Tobu Nikko ke Shimo-imachi terus pindah peron dan naik kereta ke arah ke stasiun Kinugawa Onsen. Disini terjadi hal yang menegangkan, karena kita berpatokan sama google maps, kita mengira bakal lancar-lancar aja tapi ternyata google maps tidak terintegrasi dengan nikko all pass. Untuk nikko all pass, kereta yang bisa dinaikin itu terbatas dan ternyata untuk naik kereta yang dicover ama nikko all pas, kita harus nunggu lagi hampir 1 jam. Awalnya agak galau bisa nyampe tepat waktu apa enggak, tapi yaudah kita paksain tetep jalan wkwk. Seneng capek kecewa bareng ini. Alhamdulillah dengan jogging kita akhirnya nyampe di onsennya jam 20.25. 5 menit sebelum last admission. Onsennya sendiri tutup jam  21.00 jadi kita masih sempet berendam sekitar setengah jam. Malem itu bahagia banget rasanya….. masuk ke pemandian air panas outdoor sambil ngeliat bintang di langit. Malem itu pertama kalinya gw liat bintang begitu banyaknya semenjak tiba di Jepang. Mungkin karena daerah Nikko ga begitu tercemar sama polusi cahaya. Buat jalan pulangnya, kita juga nunggu hampir 1 jam sampe keretanya jalan. Disitu udah makin gila aja orang-orang, nyanyi-nyanyi mars himpunan, yel-yel itb, mars teknik. Nyampe hotel, bukannya langsung tidur tapi main kartu dulu :”) terakhir kali main kartu tuh di lab telkom wkwk kangen juga.

Abis Onsen

Nungguin kereta

Privat Train

Hari kedua, belajar dari pengalaman hari pertama, kita ga boleh ngaret lagi. Jadi opsinya ada dua, bis nya ada yang jam 06.30 atau 08.30. Bedanya 2 jam sendiri… untungnya kita semua berhasil bangun jam 5an jadinya berhasil naik yang 06.30. Destinasi hari itu bertema alam. Pertama-tama kita ke lake Chuzenji, airnya jernih sampe-sampe memantulkan pemandangan langitnya.

Lake Chuzenji

Setelah itu kita ke Kegon waterfalls, buat masuk kesini keluar biaya 500 yen. Spotnya bagus banget buat foto. Disini juga ada toko souvenir dan cewe-cewe pada bikin koin yang ada nama merekanya.

Koin dengan ukiran nama

Jam 10an ternyata udah laper lagi dan mulai nyari jajanan di sekitar sana. Untung nemu yang murah(read: ga sampe 500 yen).

Isinya sayur semua

Destinasi selanjutnya adalah Senjogahara Marsh, disini kayak savana, udah kayak bukan di Jepang. Langitnya juga alhamdulllah lagi cerah banget.

Setelah itu ke Ryuzu waterfalls, disini kita bisa ngelihat air terjunnya lebih dekat dan masukin kaki ke sungainya. Selain itu kita juga jalan nyusurin sungai, rutenya udah ada gitu pake balok kayu jadi relatif aman hehe. Kita juga naik tangga ke atas air terjunnya, disitu ada danau dan agak bau belerang.

Ryuzu Waterfall

Abis dari situ, kita balik lagi ke arah stasiun tobu nikko buat ngejar kereta yang 17.30. Sambil nungguin bis ke arah tobu nikko, kita menikmati pemandangan sore hari di lake Chuzenji. Pas pulang ternyata bisnya lumayan padat dan akhirnya kita berdiri sepanjang perjalanan. Yang serunya, jalanan pas pulang sangat berkelok-kelok, jadi kayak kelempar-lempar gitu deh. Untungnya nyampe stasiun jam 5 kurang, jadi berhasil ngetag tempat duduk di kereta hehe. Btw sebelum pulang ke dorm masing-masing, kita bertujuh ke kampus suzukakedai dulu buat nemenin iffa ganti medium. Soalnya kalau sendirian serem gitu. Pas gw masuk ke labnya emang berasa lab banget. Beda sama lab gw yang isinya kebanyakan komputer wkwk. Setelah itu baru deh pulang.

Budget buat perjalanan ke Nikko ini 13ribu yen. 5000 yen buat penginapan, 4620 buat Nikko All Pass dan sisanya buat jajan&oleh-oleh. Overall worthed hehe, berikutnya kalau ada kesempatan ke Nikko lagi, pengen nyobain ke Tobu World Square atau Edo theme Park. Thanks berat buat semuanya apalagi andrew yang udah jadi fotografer terbaik.

YSEP Tokyo Institute of Technology - November 2016 Third Week

15 November 2016

Basic Japanese 3 Class dan sorenya kumpul kelompok buat diskusiin presentasi fieldwork skill

16 November 2016

Fieldwork skill presentation, jadi kelompok gw sendiri memilih tema tentang pernikahan menurut perspektif orang Jepang. Dari hasil observasi dan wawancara, kebanyakan orang Jepang pengen nikah di umur 30an, mereka juga mau nikah setelah punya pekerjaan tetap. Berbeda dengan Indonesia yang kebanyakan nikah di usia 20an dan belum memiliki penghasilan tetap. Lalu dilanjutkan dengan lecture class SJCI. Hari itu bill dorm tiba*shock*

17 November 2016

Basic Japanese 3 Class dan presentasi akhir Advanced Signal Processing. Jadi gw ngambil kelas ASP dan penilaian dari kelas ASP cuma dari presentasiin paper orang. Ga ada nilai absen, pr atau ujian tulisnya hehe.

18 November 2016

Pertama kalinya ke kampus Suzukakedai. Kampus ini letaknya lebih dekat kalau dari Aobadai, selain itu di kampus suzukake, gedung tertingginya ada yang sampai lantai 21. Kafetarianya menurut gw juga lebih bagus di suzukake. By the way, hari itu gw ke suzukake buat bantu temen lab, key, buat ngukur Received Signal Strength dengan bantuan drone. 

View dari lantai tertinggi di suzukake

19-20 November2016

Jalan-jalan bareng genk Indonesia(YSEP dan ACAP) ke Nikko, selengkapnya disini

21 November2016

Hari itu sebenernya ada seminar mingguan lab, tapi karena selasanya ujian basic japanese 3, gw cabut wkwk. Memanfaatkan hari itu buat belajar aja.

YSEP Tokyo Institute of Technology - November 2016 Second Week

8 November 2016

Setelah sebulan lebih, akhirnya dapet kesempatan buat diskusi sama sensei tentang research project. Gw memutuskan buat bikin simulasi entah apa itu, karena kalau projectnya tentang pengukuran, data yang diperoleh ga boleh dipake buat skripsi di Indo. Terus sorenya setelah kelas bahasa Jepang, gw pergi ke Donki Hote buat beli tas. Tas yang sebelumnya udah mau rusak

9 November 2016
Kelas Fieldwork skill, seharusnya presentasi tapi karena kelas berikutnya akan ada study tour, jadinya diundur minggu depan. Study tour SJCI hari itu adalah ke Nissan Opama Plant

13 November 2016
Istirahat dan malas-malasan di dorm(lagi khatamin anime ceritanya)

14 November 2016

Advance Signal Processing, Seminar Lab dan briefing pengukuran. Di Lab Jepang itu semuanya serba terstruktur dan informatif, mau melakukan pengukuran aja ada briefingnya, mau make alat aja ada prosedurnya, ga bisa sembarangan. 

YSEP Tokyo Institute of Technology - Fieldwork Skills Reflective Comment

Fieldwork Skills Reflective Comment

The first time I heard about fieldwork skill course was when I still in my country, Indonesia. I was exploring about syllabus of YSEP student. There were a lab research and 3 compulsory subjects which we must attend. One of them is fieldwork skills. I had no idea what the course would be, for another course like study on Japanese companies and industries, I could imagine that I will visit some Japanese factories or industries. I thought that that class would be boring, but I was wrong. I learn a lot of things in this courses. The teacher, Tom Hope, explained very well about the objective of this course. He also speak clearly and have 2-way communication with students. I also fascinated with the environment of the class which allow student to discuss freely especially about culture in Japan. Since we come from many different country, I can comprehend a lot of distinct perspectives and opinions. I also learn about how to observe something correctly, how to interview someone effectively and how to analyze them. Thank you very much for the lesson. 

YSEP Tokyo Institute of Technology - Study on Japanese Companies and Industries: Nissan Oppama Plant

Oppama Plant Factory Visit

Konnichiwa

The second study tours in the Study on Japanese Companies Industries held on November 9, 2016. The destinations that day was the Nissan Oppama Plant, where the design, manufacture, test and research of vehicles Nissan products are conducted. Because there was evacuation simulation for disaster on Ookayama campus, so we departed earlier at 11:40. The trip was quiet tired since it took approximately 1 hour 30 minutes. When we arrived, we were ushered into the lobby where there were few cars on display, as well as models of Nissan car manufacture. On the wall there were infographic about the history of the company Nissan and how to design and product the car.

At 13:30, we were greeted in the meeting room and listen to brief explanations about the history of Nissan and also about manufacturing process. Nissan cooperate with Renault and they initiated Alliance Production Way. The Alliance Production Way (APW) is the production method that is used by both cooperation by integrating the approaches to production, know-how and best practices in manufacturing from both companies.

There are several main processes in the production way. 

1. Vehicle Assembly

• Stamping
• Press machines cut and form rolls of sheet steel into automobile roofs, floors, doors, and other body panel parts. High-tensile steel is used extensively to reduce weight, while highly corrosion-resistant steel is used for protection against rust
• Body Assembly
• Robots weld the stamped panels into a vehicle body (known as a body-in-white). This is the most automated area of all vehicle production operations, for modern robotics provide the extremely high accuracy needed in this stage
• Painting
• The assembled body-in-white is thoroughly washed to remove any trace of dirt, dust or other foreign materials, then moved into a paint booth. Here the body receives multiple layers of paint, including primer, surface and top coating.
• Assembly Trim Line
• Seats, instrument panels, carpet, bumpers, windshields, trim and other parts are installed.

2.  Making Engines and Chassis

• Forging
• Crankshaft forings are produced from round steel bars heated to 1200 degrees Celcius automated forging machines
• Stamping
• Steel sheets 2-3 mm  in thickness are cut and stamped to make suspension parts that require high structural strength
• Casting
• Iron and aluminum are melted in furnaces at 1500 degrees Celcius and 700 degrees Celcius respectively, and poured into dies to make engine and chassis parts.
• Machining
• Chassis part are machined on a fully automated line
• Welding
• Stamped suspension parts are welded together by automatic welding robots
• Machining
• Cylinder heads, crankshafts and other engine parts are machined on a fully automated line. Accuracy to a thousandth of a millimeter is required in these processes. 
• Assembly
• Chassis are assembled according to the same sequence of customer orders and sent to vehicle assembly plants
• Cylinder heads and other parts are installed on cylinder block to fully assemble engines in the same sequence in which customer orders were received
• Inspection
• Performance, emissions and other aspects are rigorously checked using a computerized test bench

3. Major Component Mount

• The engine, transmission, axles and other major components are installed in the vehicle body as it moves down the assembly line

4. Assembly Line Roll-Off

• With the assembly completed, the vehicle's radiator is filled with coolant and a small amount of gasoline is placed in the fuel tank. The car is driven manually off the line for a thorough inspection and performance check

5. Final Inspection

• The finished vehicle is put through a running test, and brakes, instruments, lights and other functioning parts are checked and adjusted. This rigorous quality inspection also included an exhaust emission test and a leakage test conducted in a high-pressure shower.
