Guten Tag!

Strict on the rule, coming on time, beer addict, well prepared, honest are some on The German Characters.  Last year, i went to Germany on 2014. Within 3 days, i went to North Rhine-Westphalia. Before visiting to Dortmund to had business meeting, i went to Aachen to visit my friend. It had been long time for us to not meet up since we had graduated from University.

Ohaiyo Ghozaimasta,

This month (on early of August 2015), i went to Japan to carry out some performance tests of plant activity at Himeji, Hyogo Prefecture, Japan. Living in Indonesia with slow rhythm of work culture, i was surprised with Japanese Style. Always on time, dedicated behavior, hard work, and humble are the Japanese style.

Workshop

It was my first experience to work together with some Japanese. Due to the interest of the project, i could stay in touch with high official and expert engineer from that Japanese Company. Based from my experience to work in Indonesia, i felt some differences between Indonesia and Japanese’s style. Read the rest of this entry »

Holla.. (Spanish style)

It has been long time for me to back at my blog again. My last posting was on writing of engineering on June 2014 (1 year ago). There are so many happened on my life on 2015. I think that it is one of the difficult and joy period which i have ever faced. There are two things which make me headache, BOUGHT new house and got MARRIED. Finally, they could have done well (Alhamdulillah : Thank to Allah).

On bought new house

My dad said that it was better to had a house before got married. When your financial (salary) is very limited, you MUST give your focus on one important thing. You had to choose weather on got married first or having a house. After having intense discussing with my princess as my boss, we decided to postpone our wedding and focused to buy new house.

In case of testing the fuel such as liquid, gas, and coal, we have to refer to the ASTM standard. You can download the standard below :

MS5001 Gas Turbine_MS5001 Gas Turbine_660x450

Dear readers,

This is the first time for me to write my blog in English. I were asked by my boss to test the using of biofuel in the industrial gas turbine. As we knew that GT could use biofuel as their fuel although biofuel has difference properties from the fossil fuel. There are two difference biofuel that used for the testing. We used biodiesel or fatty acid methyl easter (FAME) and pure palm oil (PPO). From the chemical properties, we knew that FAME similar with solar or diesel fuel. For the first test, We blended the FAME and solar fuel in the difference ratio then tested into the GT. For the second test, we blended PPO and solar fuel in the difference ratio then tested into the GT too.

Batubara Indonesia

Batubara adalah sisa tumbuhan dari jaman pra sejarah yang berubah bentuk yang awalnya berakumulasi di rawa dan lahan gambut. Penimbunan lanau dan sedimen lainnya, bersama dengan pergeseran kerak bumi (dikenal sebagai pergeseran tektonik) mengubur rawa dan gambut yang seringkali sampai ke kedalaman yang sangat dalam. Dengan penimbunan tersebut, material tumbuhan tersebut terkena suhu dan tekanan yang tinggi. Suhu dan tekanan yang tinggi tersebut menyebabkan tumbuhan tersebut mengalami proses perubahan fisika dan kimiawi dan mengubah tumbuhan tersebut menjadi gambut dan kemudian batubara. Pembentukan batubara dimulai sejak Carboniferous Period (Periode Pembentukan Karbon atau Batubara) dikenal sebagai zaman batubara pertama yang berlangsung antara 360 juta sampai 290 juta tahun yang lalu.

Mutu dari setiap endapan batubara ditentukan oleh suhu dan tekanan serta lama waktu pembentukan, yang disebut sebagai ‘maturitas organik’. Batubara dibedakan menjadi berbagai jenis tergantung kepada suhu dan tekanan seperti yang telah disebutkan di atas.  Jenis jenis batubara adalah :

a) Gambut (peat)

Golongan ini sebenarnya belum termasuk jenis batubara, tapi merupakan bahan bakar. Hal ini disebabkan karena masih merupakan fase awal dari proses pembentukan batubara. Endapan ini masih memperlihatkan sifat awal dari bahan dasarnya (tumbuh-tumbuhan).

b) Lignite Read the rest of this entry »

Dalam ilmu perawatan atau pemeliharaan mesin, terdapat beberapa metode dalam pemeliharaan.

VIBCONS-KGE36CMM1vibrationanalysis

Diantaranya adalah breakdown, preventif, dan prediktif maintenance. Perbedaan ketiga metode perawatan tersebut adalah :

1. Breakdown maintenance : peralatan mesin diganti pada saat rusak

2. Preventif maintenance : perawatan mesin dilakukan secara berkala, pada umumnya melalui indikator lamanya waktu operasi seperti jam, hari, atau bulan. Read the rest of this entry »
