Abstract

Waste Solid and liquid in production of is disturbing to the humans. Production tofu in Kediri use traditional methods, so the level of efficiency in the use of resources (water and raw materials) is low and the level of waste production is relatively high. Bioenergy is a source of energy produced by biological resources such as plants, vegetable oils, and livestock and agricultural waste. The type of energy produced is gas, liquid, or solid form. The energy can then be used to produce heat, motion, and electricity depending on the tools used and the user's needs. Biogas is a gas mixture produced from the activity of methanogenic bacteria under anaerobic conditions or fermentation of organic materials. Biogas is a product of anaerobic degradation of organic substrates. Because this process uses the performance of a mixture of microorganisms and depends on various factors such as temperature, pH, hydraulic retention, C: N ratio and so on so this process runs slowly. This study aims to determine the comparison of constituents in the utilization of tofu waste water production as an alternative biogas energy. To make biogas tools used include: Digester and manometer. The raw material used for the first composition is 30 liter first tofu liquid waste with 50 ml Em4 and 2 liter coconut water. As for the second composition, the first liquid tofu waste is 30 liters with 50 ml Em4 and 500 ml molasses. Data was taken for 14 days with observations made every day. From the results of the normality prerequisite test, it was found that the two data were normally distributed. While the homogeneity prerequisite test results, it is stated that the data are homogeneous. Because what is compared is 2 data, it is sufficient to use the T-Test. T-Test results show that the second composition is better than the first composition. So it can be concluded that making biogas from liquid waste added with molasses gives better results than making biogas from tofu liquid waste added with coconut water.
