Abstract

Dependence on fossil fuels requires a solution through alternative fuels. Ethanol is the recommended solution because it is easy to produce using raw materials that are abundant in nature, such as mangrove fruit. The Rhizophora Mucronata type of mangrove fruit contains 45.22% carbohydrates and is not used as raw material for human food. The research aims to produce ethanol biofuel from mangrove raw materials using multistage distillation. Experimental methods were applied at the stages of mangrove flour production, mangrove flour property testing, saccharification and fermentation, mangrove ethanol distillation, and analysis of potential performance and exhaust emissions. The research produced mangrove biofuel with an alcohol content of 28% which was produced from mangrove flour and had an ash content of 1.91%, protein, 2.24%, fat 0.53%, and water 11.61%. In addition, mangrove biofuel has higher viscosity and density properties than Gasoline at 0.8067Cp and 0.8115 g per mL respectively. The use of mangrove biofuel as a result of experiments is predicted to reduce fuel injection performance.

Abstract

Sugihmanik, Tanggungharjo District, Grobogan Regency have tofu industry center with 30 Micro, Small, and Medium Enterprises (MSME). It is hoped that these MSMEs can improve the community's economy, but on the other hand they can also cause pollution problems for the environment. The waste produced in tofu processing production activities reaches an average of 67,997 m3/day from tofu production, with a total demand for soybeans of around 3200 kg/day. Some of this waste is thrown into rivers, which hurts the ecosystem in a chain that results in the death of aquatic animals, the agricultural environment, and unpleasant odors. Based on the problems in MSMEs, this activity proposes the technology design for converting biogas gas into electricity. The method to solve this problem is to utilize energy from tofu industry waste converted into electrical energy. In implementing biogas conversion technology, it can be tested with a partner electricity load of 1500 watts. However, this technology still has several obstacles. When changing modes, the generator machine for converting biogas into electrical energy requires a manual synchronization system. So, it requires training from partners. In the future, this activity will continue with the development of automatic synchronizing control systems, making it easier to use
