This gas-making process begins by cutting the stems and leaves of water hyacinth. After that, pieces of water hyacinth is inserted into the reactor tube is made of two drums joined together. This process takes seven days to produce gas from decomposition of water hyacinth. So, for seven days, the gas from the decay of water hyacinth will flow into the reactor tube for later accommodated in a special tube.

In order to not run out of gas, a powerful tube fermentation capacity was filled with 80 pounds on a regular basis. A total of 30 kilograms of water hyacinth on the drum fermentation, can only be used in a day. Especially, when used continuously.
