SJCI Trip : Visit to Kamaboko Village

greetings ^^/
I am sorry that recently I didn’t post something that not ‘game-related’ 😛

here we go.. another Study on Japanese Companies and Industries
in this trip, our destination was ‘Suzuhiro Kamaboko Village”
er? what kind of place is that? let me explain

Suzuhiro : basically, this is the name of the Family (which is then become the name of the company).. this family was one of few family who started making kamaboko as an ‘integrated-factory’ one.. even though it used very simple technology back then..

Kamaboko : this is the main topic.. if you are Indonesian, you will know ‘pempek’, ‘siomay bandung’, or the closest thing with this kind of food is ‘otak-otak’
yep.. kamaboko is a kind of seafood from Japan which is made from ‘fish-paste’ (すり身 「すりみ」surimi)
one of the example of kamaboko is shown here :

(image : – official site of Suzuhiro Kamaboko Company)

the texture of this food is ‘elastic’.. make this seafood ‘remains’ inside our mouth for a little time while we try to crush it (om nom nom)
this food has unique smell which attract fish lovers to eat
but for your information, this seafood product has wide range of price from hundreds JPY to 4,000 JPY for the premium quality

Village : this is where the main office and main factory of Suzuhiro Kamaboko Company
it’s located in Odawara City, Kanagawa Prefecture.. for the exact place, you can go to the Google Maps
this ‘village’ has the main factory of Suzuhiro Kamaboko Company which produces many kinds of kamaboko everyday
near the factory, there is a ‘Kamaboko Museum’, place where we can try to make kamaboko

I tried that interesting thing : make kamaboko.. and chikuwa (chikuwa is another product of fish-paste)
it needs very accustomed hand to make good kamaboko
the fish-paste must be freed from air by shear it with special knife, need to be patient so that the texture of fish-paste won’t be crushed
then, stick it to a rectangle of wood before baked in the oven
it’s really that simple in the word
and also when the pros gave the example
but really.. it wasn’t that easy .__.
for chikuwa, instead of stick the fish-paste to the wooden rectangle, we stick-and-roll it to a bamboo shoot then grill it

although the shape wasn’t a good looking one, but the taste is… really good
here are the result of ‘my hands’

the chikuwa I made

the chikuwa I made

the kamaboko that I made

the kamaboko that I made

my impression :
actually, I like this kind of food.. also the ‘otak-otak’ thing.. so a visit to this village is a paradise for me (we even got a free sample of kamaboko :3)
the experience of making kamaboko is very impressive one.. it also can attract children to come and try kamaboko.. then like it as a daily food

conclusion :
come to Japan
try by yourself 😉

for more information about kamaboko, Suzuhiro Kamaboko Company, and the Kamaboko Village, this link can provide you little information.. but if you can understand Japanese, this link is much much informative

cheers ^^



today, students of YSEP who are Focus on Experiencing Japan (6 months program) are officially graduated..
it is weird enough that I felt we just got a Welcoming Ceremony yesterday (actually we had it early Oct) and today we had to attend the Completion Ceremony
time elapses like a flash..
remember when we met for the first time? when we were helding Welcoming Ceremony in the 10th Floor of West 8?
then, our first TOJ class and first SJCI to the Life Learning Center?
remember that our scream of “KAJIDA!” and fear of earthquake simulator?
then we explained our countries in the front of class
visiting Chisetsu Shogakko
and trip to Atami.. where we took onsen together.. being what we really are
autumn changed to winter.. but our friendship could give  the spring’s warmth among us.. let the flower of caring each other blooms in our heart
we’d played together.. cooked in the same pan.. and studied in one room
we shared laughter, some arguments, and gave smiles
but after all, every seconds I shared with you were precious memories for me
and at last.. you have to go back to your countries.. for continuing your fights.. for reach your dreams

then, here I would like to say thank you for you all,friends..

to Mr-2nd-Handsome (after Chien, sorry, but Chien can’t be replaced.. keke) Chen, my classmate in Jpb 4.. even I rarely talk to you, because you are living in Umegaoka.. but still, your appearance in that class made me feel that I am not alone,, thank you for the sashimi information.. I will definitely come there

to Mr-Neighbor Not, you are gooo neighbor.. never made any noise, never broke down the dorm.. .___. hahaha.. kidding.. thank you for being my friends.. and I am sorry that sometime I woke you up when I tried to wake Ade up.. kekeke

to Mr Al-CapoMafia Daniele, we didn’t talk much, but I know that you have the potential to be a mafia boss.. kekeke.. your words are strong.. and your bravery can’t be replaced.. thank you for the night we spent at Atami

to Mr Otaku Kiwon, you with your own world.. and full of information, especially about anime and some amaizing stuffs.. thank you for inviting me to the karaoke and told me the God Knows song 😉

to Mr Handsome Cooking Master Berny.. kyaaahh.. you are too handsome and have an excellent cooking skill.. thank you for your recipes, the trip to the Nishi Izu, and many conversations we had.. please teach me some more German recipes.. kekeke

to Silent Jung A Hyeong(???!!).. I am sorry if I’d ever been annoying.. maybe.. kekeke.. thanks for “that day” and for Korean songs especially Roly Poly.. I am studying the dance right now.. kekeke.. and I hope you can be my tour guide at Seoul next March 😉 thank you for some conversations too., even that it was really hard to have talk with you 😛

lastly, for the Mr Ninja Ade, hemm.. I think just one sentence for you : gila lo De!! hahahaha.. keep your attitude like that and the world is in your hand bro.. hope you can reach your dream.. and we’ll meet again someday.. soon… soon.. hahahahaha.. mandi lo de! wkwk

last words, as I said before, I hope this is not the end of our meeting.. or even worse, the end of our friendship.. no
this is the begining of an international relationship.. that could bring brighter future for the world
it’s very nice to know you
it’s a treasure for me to have memories with you


Japan, Samurai Spirit Behind Sophisticated Technology

I read my friend’s blog and I wonder how if I post a same thing too? ㅋㅋㅋ
So actually, this is my Topics on Japan 1 Final Report in theme “Japan’s Strength and Weakness”
Here we go

In my opinion, strength and weakness of Japan can be summarized in one factor : the pride of their nation. This pride could be the really strong strength for Japan to face and be the top of the world, but this also can sink Japan to the deep of destruction if they don’t know how to control it.
Based on my reading, Japan is one of the country which has only one race in general. They had been united as whole Japan since long time ago. They had relatively-stable government system and unique customized life style. Their old vision-of-strong-country is their neighbor, China. They had felt comfortable with their life, believed that they need no outsider help because they could fulfill their needs by themselves, until the day western countries came.
Western country that first came to Japan was the Portuguese in 1543 with their “Black Ship”. This arrival of Portuguese made their eyes opened. China was beaten by Portuguese and it made Japan shock. They realized that outside their world, there are many other better technologies than they had known. Then, they started to mimic the new technologies from western country by learn it. Step by step, Japanese people way of understanding and vision of the future changed, but still, they had one proud of themselves. They believed after learning new things, they could develop it by themselves and fulfill their needs. And it’s true, Japan now becomes one of frontier in technology.
In my opinion, the bond between Japanese people because of their pride of their nation is very strong. They still do their old customs and keep the inherited culture even they had developed many new cutting edge technologies. Some of the customs which I notice still living inside Japanese people are manner and way of life. Japanese manner, although many people said that it starts to disappear among youths, especially in the big city, is one reason that Japanese people still believe and respect each other. Simple way of life including ofuro and farming life are not adjusted to the new technology : new technology is developed by reference of old customs. These condition makes Japan is nearly invulnerable to cultural attack from outside Japan. This is one of strength of Japan that I always think as “Samurai Spirit”, a spirit to be independence by their own way but still could be the leader of community.
But, beyond of that, in my perspective, this pride could harm Japan because of globalization era. Furthermore, Japan’s “aging population” make it worse. Nowadays, global world open their market and decrease boundaries between country for trading, including human resources trading. If Japan is still convinced to keep their pride exaggeratedly by not cooperating to other countries, especially for the human resource, Japan will lost their momentum to expand their life as one of world frontier in technology. Fortunately, it seems Japan government knows this issue and start to make a move. Nowadays, I see English course becomes more popular and many foreigners are accepted as researchers or workers. I don’t know why or and why should English become one of the most important language in the world. I myself was so impressed that Japanese people still tend to defend their Japanese when Indonesian people are now proud if they could speak English. But still, for now, learning English as a “weapon” to face globalization is important. I found something interesting about this English learning, the differences between Japanese and Indonesian. Here, at Japan, people are proud with their works, their product, and their customs, as well as their language. So everything here are in Japanese, including new technologies like smartphone, laptops, and even games. But back to Indonesia, since we still can not produce best things by ourselves and import many new technologies, we have no option than learning English to use new technologies, and again, including games. Japanese kids are playing games in Japanese, while Indonesian kids won’t found games in Indonesian, so that they have to learn English to play. This rule also applies to smartphones and laptops. This simple thing made rather big differences between learning English as Japanese and Indonesian. Japanese learn English mostly by course, whether in school or special courses, but Indonesian learn it by habit, since as I said before, we have no option than learning English to use technologies for our life.
One more effect of the exaggerated pride of nation in my opinion is lack of human power. This refers to productive-age people. The nowadays trend in Japan is success career life. Whether men or women, they tend to life hard-successful-career-life that makes they don’t want to marry early. This maybe one of reason that causes Japanese “aging population”. If no more new productive-age people in Japan, their cutting edge technology and sophisticated research won’t work. One of the option to resolve this problem is making people from other countries to come as fresh human power to Japanese academic and industrial world. If the exaggerated pride of nation works, it could resist foreigner to help their community and leads to annihilation of sophisticated technology that had been struggled until this second.
My conclusion is, Japan’s “Samurai Spirit” is the most powerful strength that leads Japan to be able to stand by their feet and lead the world by courage to be the best, but still, Japan has to be open to the changing global world trend and keep the cooperation with other countries, especially in human resources.

oleh-oleh dari jalan-jalan ke pabrik Nissan (Indonesian ver.) – opini gue

this is Indonesian version.. hehe

gw males ngulangin postingan gw.. apalagi nerjemahin 😛 so, please donk ah kalo mau baca postingan berikut ini silakan baca dulu postingan bahasa Inggris (yang banyak salah dan ngaconya mungkin.. maaf kalo jadi keriting gara2 kata-kata saya nggak bener) tentang kunjungan ke Nissan hari ini di link ini

ga bosen-bosen diriku menyatakan bahwa ketika make bahasa Ibu, ya gw curcol :3
kali ini mungkin curcolnya agak berbobot (soalnya abis makan nih gw.. jadi nambah beratnya gitu.. wkwk)
*muka serius*
ini mengenai pendapat saya tentang masa depan si fuel cell
*cetar-cetar* *petir menyambar*

ah.. ga asik kalo pake bahasa terlalu formal.. jadi maap yak.. racauan saya kacau kayak biasa 😛

yang jadi kepikiran sama saya tentang ini fuel cell adalah.. kenapa orang mau ngembangin fuel cell ya?
emang sih, zero emission.. tapi.. kayaknya nggak terlalu mengatasi masalah “kekurangan energi”
*nb, postingan ini penuh CMIIW.. silakan dihujat ato dikomentari.. karena ini ngeposting nggak komprehensif jadi datanya nggak valid
kenapa nggak terlalu mengatasi?
saya ngambil especially yang PEMFC ya.. soalnya hari ini ketemunya itu
nah.. si PEMFC ini kan make bahan bakar yang muahal dan susahnya minta mampus buat dibuat : hidrogen
yah.. saya masih katrok sih soal teknologi pemroduksi hidrogen yang lebih maju sekarang.. maaf kalo nggak tau yak.. cuiiingg
habisnya.. yang saya tau mbikin hidrogen itu cuma dari dua hal : ngeelektrolisis air, ato mecah hidrokarbon (termasuk di dalamnya biomassa)
cling-cling.. pikiran gw adalah :
1. kalo make elektrolisis.. listriknya berapa cuy? jelas-jelas reaksi air jadi hidrogen dan oksigen itu energi bebas Gibbs’ nya negatif (dalam temperatur dan tekanan ruang loh ya).. yang otomatis (ya jelas lah.. namanya juga elektrolisis) butuh energi (dalam kasus ini listrik.. sekali lagi namanya juga elektrolisis) yang nggak sedikit (bisa dibilang bhuanyak banget)… so so so soooo.. rugi donk make listrik segitu besar buat ngebikin hidrogen trus hidrogennya ntar dibikin listrik lagi.. dan pasti tau lah.. banyakan PLT sekarang PLTU ato PLTD yang bahan bakarnya dari apa? yupp.. batu bara ato fossil fuel (diesel maksudnya.. eh.. solar ding kalo di Indonesia)
dan lagi, efisiensi dari PEMFC (secara finansial nih yak biar gampang dibayangin).. nggak tinggi.. yaitu sekitar US$49 (sekitar 500 rebu rupiah) per kilowatt (buat perbandingan, TDL Indonesia yang nggak subsidi adalah sekitar 1.400 rupiah)
2. kalo mau make hidrokarbon.. errrr… masalahnya ya jelas sekarang kan bahan utama buat bahan bakar ya itu hidrokarbonnya bahan bakar fossil kan? jadi ya.. sama aja boong.. nggak ngeganti.. malah jadi rugi.. kenapa? ya karena nggak semua hidrokarbon ngecling-cling jadi hidrogen gitu aja kan? rugi lah.. kalo make biomassa.. ada sih masa depannya.. tapi kalo dihadapin sama masalah lahan dan pertumbuhan penduduk.. bisa jadi perdebatan lagi sih

nah jeleknya.. di sini saya cuma nguneg-nguneg.. jujur.. belum ketemu tuh solusi yang bisa bagus
masalahnya.. kalo menilik teknologi yang sebenernya (menurut saya) paling oke (udah nggak make si hidrokarbon ato biomassa, apalagi listrik), yaitu solar cell.. kayaknya masa depannya masih suram.. trus kalo make nuklir.. sekarang bahkan negeri sakura ini udah takut mau make nuklir lagi.. dan juga.. ada peraturan bahwa salah satu hal yang nggak boleh diskala kecilkan adalah nuclear power plant (yang jelas-jelas dibutuhin kalo mau bikin vehicle dengan teknologi itu.. gaje juga kan kita mau bepergian bawa-bawa pabrik nuklir segede gaban gitu?).. habis.. pada takut ada bom atom (bom nuklir) lagi sih
hem hem.. emang susah sih bikin sumber energi yang ramping dan portabel sehingga gampang dibawa dan didistribusikan.. juga yang paling penting didapet sih.. selain bahan bakar minyak kayak yang sekarang kita nikmatin
apa yaa?? ada yang punya ide?

yak.. postingan ini berujung dengan gaje.. dan kegalauan saya tentang masa depan energi..
sebenernya ada uneg-uneg lain tentang kalo ntar FCV jadi bener mendunia sih.. ampe masuk negeri kita.. apaan? ya kalo si Jepang bilang bisa bikin 5000 gas station (hydrogen gas station) di 2050.. Indonesia.. kapan? hemm.. nggak pengen meragukan negeri sendiri sih.. makanya nggak diperpanjang

yah.. maaf kalo postingannya mengecewakan.. tapi ini bisa jadi pemikiran bersama deh
apa ya kira-kira sumber energi yang asik.. tapi bisa dibawa-bawa (kayak bawa kacang atom.. apa deh ini .__.)

dan jujur.. saya ngantuk (00:13 JST dengan perjalanan cukup lumayan ke Nissan di Yokohama tadi)

dadoohh.. sampe ketemu lagi
dan nggak bosen saya bilang
Jaya Indonesia

souvenirs from Nissan Factory visit

today, me and my friend of YSEP went to Nissan Factory near Yokohama
it’s a regular class named Study on Japanese Companies and Industries (like what had brought me to Atami)
some of the story I got was too fabulous to forget so I want to share here ^^

first thing is the “douki-seisan” principal of Nissan Company
this principal means that they will produce very exact car that customers want and deliver it at the promised time
they keep their principal by doing very neat and clean production system
I went in to the factory.. assembly factory
there, the cars are built..
there are one “main line” and several “sub line” that produces 60 cars every hour.. means one car in one minute.. *phew
and a single car is made for 60 hours total.. since the stamping the parts, painting, until final checking..
I saw that about 2,000 workers were doing the car production.. each of them has a job to assembly 5 to 10 kinds of parts for 2 minutes.. *phew again.. amazing..
one thing that makes me more amazed was the cars which were being produced in the lines are not only one kind of car.. but several kinds from simple SUV with gasoline to funky with battery cell attached as the energy source
they were being produced simultaneously in one big line by that workers..
the secret to make the production could be done fast was : the workers just have a job to assembly.. not choosing the right parts.. so every parts that designated to each car had been prepared and delivered by simple wheel-footed robots
and the production was like a flow of water.. very smooth.. simultaneously

second thing is the FCV.. Fuel Cell Vehicle
Nissan Company develop fuel cell technology to make “future car”.. the main advantage of this type of car is zero emission.. actually, it still has an emission.. but not a pollutant.. it is water
how can? if you had known about fuel cell technology, so you could pass these some explanation (by my way.. maybe not exactly true)

-the explanation of fuel cell begins here-
first, what is fuel cell?
in simple. fuel cell is an energy source that produce electricity (that’s why it was named ‘cell’ like a battery) with a continuously renewed “real energy source”.. which called “fuel”
why is it called fuel is (maybe) because the principal of this kind of “fuel” to produce energy is just the same as the “real fuel” that we know : combustion reaction (yeah.. not exactly the same.. but basically the overall reaction does the same)
this combustion reaction means reacting the fuel with oxygen (or another oxidizing agent) to produce energy and small waste of emission
in fact, the definition of fuel cell is not restricted to that hydrogen type.. there are more kinds of fuel cells
basically, the core principle of fuel cell is electron exchange between anode and cathode by means of electrolyte (a media that can be used by electron to be transfered.. could be solid, or liquid.. or gas.. even plasma).. that electron transfer produce electricity.. so there is energy
in common, the “fuel” that is used for fuel cell is hydrogen
so, as we know, the reaction of hydrogen with oxygen (combustion) produce energy and… H2O.. or we can say.. water.. with the reaction is as follow :

and the common draft-drawing of fuel cell design is :

there are several types of fuel cells.. I will introduce them shortly.. this post is not designated to academic purpose.. so.. I won’t be so harsh 😛
Proton Exchange Membrane (PEM) Fuel Cell
this kind of fuel cell utilize polymer membrane as the electrolyte.. basically, this polymer membrane separate the anode and cathode which contains both fuel and oxidizing agent
High Temperature Fuel Cells : Solid Oxide Fuel Cell (SOFC)
actually, HTFC may refers to two kinds, one of them, and maybe the most popular, is SOFC.. this type of fuel cell uses solid material, usually ceramics called yttria-stabilized zirconia (YSZ), as the electrolyte.. it is operated at high temperature (800-1000 degree C)..
High Temperature Fuel Cells : Molten Carbonate Fuel Cell (MCFC)
this kind of FC utilizes LiKCO3 (lithium potassium carbonate) as the electrolyte which is liquified at high temperature (650 degree C), allowing the movement of the charge within the cell – in this case, negative carbonate ion
little bit different than two kinds before, the reaction of this FC is

-this is the end of fuel cell explanation-

I got a chance to ride one of the FCV there.. it was nice.. it used PEMFC with Membrane Electrode Assembly (MEA) technology, which makes the fuel cell thin and compact.. it was just like normal gasoline car.. it could reach 150 kmph but the machine’s sound was soooooo smooth.. and.. it doesn’t “smoke” but “spit out” water.. which is.. totally not a harm for environment
they said that that car could run for 500 km if the tank was fulled by 70 MPa of hydrogen
it’s nice.. and.. we can hope that it could be real “future car” with zero harmful emission.. but when it could possibly take the crown of gasoline fueled vehicles? dunno.. until today, the price of FCV is still too high to come to the market.. why?
one of the difficulty of developing this type of car is.. developing the hydrogen storage tank.. if we don’t count the bloody-work to develop thin and compact fuel cell :3
the storage tank must be safe enough (remember.. 70 MPa of hydrogen? it’s.. about 690 atm!!!) so that it won’t be broken, melted, leaked, even the inside pressure (by hydrogen) or outside pressure (by car crash maybe).. and big enough to carry sufficient hydrogen to operate the car.. the result is big strong tank that makes back seat become little bit higher than normal gasoline car.. but it’s okay
and secondly, the distribution of the hydrogen gas station.. but government of Japan said that there will be about 100 gas statiosn (currently 16) in 2015; then 1000 stations in 2020.. then 5000 stations in 2030..

let’s wait.. and maybe we could join them
to make zero emission vehicle
to make eco-friendly vehicle
to keep our children’s future saved from fossil fuel emission

ah.. if you want to know more about the company itself and some data of it, please see my friend’s post here – credit to my room-mate, Alfan Presekal-
that’s all… cheers ^^

Atami Tour

Dear all ^^
Sorry that I haven’t updated the blog recently
Now, I want to share some experience when I join special class for international students in Tokyo Tech called Study on Japanese Companies and Industries (SJCI). As you can guess from the title of the class, that class provides us, international students, information about some Japanese companies and Industries. We are taken right to the companies to learn about their works. We’d gone to Life Safety Learning Center and Fujitsu. There will be some other companies to visit after this, but last trip was special. Instead of going to factory, we went to Atami, a city near Tokyo. What we’ve done there? I will share to you here. Not only things I’d done with my friends, but also some information about Atami

General Introduction of Atami
Atami 「熱海」is Japanese word contains two kanjis:atsu (hot)「熱」and umi (sea)「海」. So, Atami means “Hot Sea”. Why hot sea? It’s because Atami is located at east sea of Japan (Sagami-nada Sea, which is connected to Pacific Ocean) and it is famous of its hot spas「温泉」since long time ago. Many people believe that hot spas in Atami have curing ability. So even The Emperor asked to brin g hot water from Atami to Edo (old name of Tokyo). The exact location of City of Atami can be found here. The hot spas are spread around the city. Further information about spas in Atami can be found in this website.

You can access Atami from Tokyo by using Shinkansen (bullet train).

Visit to Creare
Now, back to my tour. First place we visited was CREARE, a studio for the public arts in Yugawara. Public arts are, in my opinion, arts that built for enhancing view and feel of public facilities, for example wall art inside station, art glasses in church, etc. When I came to this studio, the workers were doing project of making wall art for a station in Japan. They made the wall art from ceramics. They had unique method to color their wall art. The colour of their wall art doesn’t come from poster colouring but from special paint that mixed with the ceramics then rise the colour after they were burnt. This studio also makes public art from glass. The glass workers used was abandoned glass collected by the workers. But even the glass was unwanted one, the workers of CREARE could transform them to be piece of art. Some of the glasses were made to beautiful neclace for sale.
In this public art studio, we met alumnus of Tokyo Tech from Department of Chemistry. She was graduated at 2010 and chose to do job in CREARE as a manager. She said that even she’d never studied managerial and finance in her university, she still could make herself comopetent for her job because she always learn by doing.

Atami Heartpia
This is the name of the hotel where I stayed in Atami. The hotel was good and provide Japanese-style room with tatami (Japanese bamboo carpet) and futon (Japanese style bed). I stayed with 4 other friends in one room and it was still comfortable. So you can imagine how big the room was. Same as other hotels in Atami, this hotel have hot spa. The hot spa opens from 5 in the morning until midnight. It was enjoyable and clean. There were four kinds of bathub inside the hot spa area : normal pond (about 40 degree), hot pond (about 50 degree), bubble pond (also about 40 but with bubble from the bottom), and outside pond (it was hot.. maybe around 50). It also has a sauna room but I didn’t try it. I like the bubble pond best. It was very comfortable to get massage-like bubble at your back. The outside pond was also comfortable. It was so hot so that even I went there in the begining of the winter (about 2 degree) and the sea wind was strong , the hot spa still felt very hot and comfortable. Hot spa is enjoyable way to refresh your body and release inner stress. Don’t forget, the hot spa service will always free as long as you stay in the hotel.
In the night, there was a dinner from the hotel. The menu was good. I was provided by vegetable-and-fish-only menu because I can’t eat pork. But still, it was so delicious. They prepared shabu-shabu (vegetables, noodle, or seafood cooked inside hot water), fried fish, Japanese-style salad, and sashimi (raw fish). The rice was unlimited (I ate 5 bowl of it) and the dessert was very good (cake, and fruit). After dinner, we have sharing and discussion session with Farid-san, alumnus of Tokyo Tech from Indonesia who is working for Torishima Pump right now. He explained about the condition of Japanese industry and opportunities for foreigner to work in Japan.
One thing that impressed me most was the view from the hotel.

Speech from Mayor of Atami and Atami Touring
After having comfortable night and hot spa, we went to Atami City Hall to hear some speech from the Mayor of Atami. Again, he is alumnus of Tokyo Tech. He explained some of the beauty of Atami, its legend, and recent condition. After that, we went around Atami City to see jinja (Shinto Shrine) and beach. There was a very old and big tree near the shrine which is believed by people can give you one year long life if you go around it. The beach was beautiful. There were some ships with birds on their top, like a painting.

Asahi Company Visit
Last stop of our tour was Asahi Company. It is beer company, so we visited the brewery. The customer service woman guided us to see the factory. It was nearly-all automatic. In short, the process of making beer in this factory was : malt plus some kind of yeast were incubated for some time to do fermentation, then the fermentation product was filtered and packed to be a can of beer. After having a tour (looking the machines worked), we were provided by the product of the company : beer. But I didn’t taste it. Of course. But fortunately, they provide juice and softdrink for people who don’t drink beer.


Asahi Brewery

That’s all the story
Hope it will attract you to come to Japan, and feel the comfortable hot spa ^^

Brief introduction to my research in Tokodai

long time no post >.<
warui warui..

here in Tokyo Institute of Technology (Tokyo Tech) I have to do a research to complete my task as exchange student

since I am a Chemical Engineering student.. I (suppose to be) have to do ChE related jikken (experiment)
but.. here, ChE's "trending topic" is little bit different with Indonesian's Che's..
actually, in ITB (Bandung Institute of Technology), I join General Chemical Engineering.. a sub-department in ITB's ChE that study about general things in ChE such as making reactor.. evaporator.. distilator.. or even catalyst..
and my research topic there is about catalyst (I hope it's still the same)
but here.. I do something really different from what I do in ITB.. bio-process -_-

bio-process is.. err.. branch(?) of ChE that utilize microorganisms (esp their enzyme) to do such kinds of chemical reaction
it's also a sub-department of ITB's ChE..
one more time.. it's about MICROORGANISMS.. and their ENZYMES…

*short sigh.. a moment of silence..*

so that I don't know anything about my research here..
I don't have any experience about saying hello to fungi or babysitting yeast..
my best friend solid catalyst's nowhere to found here..
but it's okay.. even maybe.. it's interesting.. to find a lot of new things here

so here's my research topic in Tokyo Tech :
Converting Waste Paper into Bio-ethanol
waste.. paper..
into.. (bio) ethanol..
paper.. ethanol..
how can it be related?
and maybe you think about bio-ethanol = energy ? yup.. you're right

ethanol is a kind of alcohol (liquor’s alcohol is ethanol though) that contains 2 carbon atoms.. and of course with hydroxy (-OH) group..
bio here is just “nick name” to distinguish this ethanol that produced from bio (living things) from other petroleum(oil)-based ethanol
usually, ethanol is produced by means of fermentation.. same process that we use to make wine.. the main ingredient is sugar.. simple one (e.g. glucose, xylose, fructose) not the polymer one (e.g. amylum.. or we can say starch.., cellulose.. kind of sugar polymer that we can find in tree or even paper)
the main processor is enzyme that produced by microorganisms.. I will explain these later..
so we back to bio-ethanol..
large usage of bio-ethanol is for gasoline substitute..
therefore, bio-ethanol is (hopefully) can resolve problem of lack energy.. that is the main purpose of this research..
Saccharification and Fermentation
Saccharification, in simple, is process that transform polymeric carbohydrate to less chained carbohydrate, or even become monomer.. Simply, we can find this process in our mouth when chewing rice (with helping hand of saliva).. we (without even hesitate) hydrolyze amylum (polymer alpha-chained glucose, contained in rice) become glucose.. that’s why we will taste little bit sweet when we chew rice for a little bit long time.. That’s the simple sample one.. The real term of saccharification that I used here refers to hydrolysis of cellulose (also polymer of glucose, but beta-chained..therefore much much harder to hydrolyze) by means of cellulase.. This saccharification process is needed in this research for converting cellulose from paper to glucose that can be fermented to become bio-ethanol
Fermentation, in simple, is process that transform simple carbohydrate (such as glucose) to become ethanol.. As I said before, this process can be found in wine making..

Why paper?
Commonly, bio-ethanol is produced from corn or sugar cane
This can be bad.. because those two are also common human’s food
So I use this paper.. waste paper especially.. that usually thrown away.. or recycled..
So here it is.. re-utilize.. become something more useful : gasoline substitute

Basic Principle
My research, simply, consist of two steps :
1. Saccharification to transform cellulose inside paper using cellulase that produced by Trichoderma reesei to become glucose
2. Fermentation for converting glucose to become ethanol by means of enzymatic activity of Kluyveromyces lactis

Problems Facing Ahead
Some parameters that I must replenish are :
1. Composition of medium to inoculate, pre-culture, culture, and do SSF.. medium is mix of many substances for microorganisms to live in.. it consist at least carbon source and nitrogen source.. and water.. the C-source of my research is that paper waste.. another C-source may be needed.. that’s the first problem that I have to find the answer
2. Condition of paper.. dry? wet? crushed? cut?
3. Condition of run : temperature? shaking speed? pH?

Future (hopefully)
If this research gets its success.. it can be a stepping stone to resolve two problems in my beloved country, Indonesia, simultaneously : paper waste problem and gasoline lacking problem
