However I, Muhammad Prehatin from Jogjakarta, have been through decades for us to fulfill our necessities of meals only by repairing electronic product and the trade off, whatever will happen I will never forget and leave this work.

Even more, I would like to develop the world channel, either scientific or the trading. Actually, we lack of capital in developing this profession.

However, we also only rely on the service of mind thus it could help the other persons.
