In the next few decades, ethanol will take on the role of replacing fossil fuels. However, for direct application to the existing vehicles, an assessment of the corrosion resistance of the fuel tank is required. Therefore, this paper presents the results of corrosion resistance investigation of fuel tanks due to the application of ethanol. A Gravimetric method is used to test the corrosion. Ethanol is mixed with NaCl at various percentages as a corrosive medium. The test results show that the fuel tank has good resistance to corrosion due to ethanol use.

Abstract. This Community Partnership Program is in partnership with BINA USAHA Small and Medium Industries which is engaged in the metal welding industry. BINA USAHA also produces equipment and simple machines for industrial processing of agricultural products from surrounding communities, such as tobacco chopper machines and coffee peeler. The production equipment owned by the partners is still conventional. This condition causes low production capacity, in addition, the existing equipment is less ergonomic, so it often creates work inconvenience for employees. Apart from low production capacity, the use of conventional equipment will also result in poor product quality, because the uniformity of the dimensions of the workmanship cannot be maintained. Meanwhile, problems in the field of management, product marketing are still limited to certain areas. This is due to the lack of information received by partners in finding areas for product marketing, lack of marketing networks and the marketing area is not yet extensive. This activity uses a participatory community empowerment model / Participatory Rural Appraisal so that it requires active participation from partners. The solutions offered to solve the problems faced by partners in this PKM scheme community service activities are: a). Equipment development, b). Production process training, c). Develop a marketing model. The output target to be achieved from this activity is the application of science and technology ROLLS BENDING MACHINE at IKM BINA USAHA, so as to increase the competitiveness of IKM products and improve the welfare of the community.

This article is the result of implementing the CSR program of PT PLN Magelang Regency branch to help solve problems in the Rahayu Manunggal Women Farmers Group (KWT). High production costs and low profits are obstacles faced by KWT Rahayu Manunggal. This problem is caused by the production process of making brown sugar which uses quite a lot of energy, including the drying process of brown sugar. Applying an energy-efficient oven at KWT Rahayu Manunggal can help overcome this problem. The concept of the oven machine is designed by utilizing the heat/energy stored in the exhaust gas produced by the sap cooking furnace. The results obtained from this system can increase profits and reduce production costs, as well as improve the cleanliness of brown sugar processing.
