Abstract

The high monthly costs associated with the use of electrical energy for the production of dairy cowsheds at the KTT Sumber Sari, as well as the problem of PLN blackouts, have a negative impact on the smooth production process. Meanwhile, KTT Sumber Sari already has a 40 m3 biodigester that has only been used for household cooking. Problem identification, socialization, product development, and modification are the methods used in this program. The problem that has been solved as a result of this community service program is the provision of a biogas-fueled electric generator with a capacity of 5 kWatt. To optimize the performance of the engine driving the electric generator, a few changes were made to the standard gasoline-fueled genset propulsion engine, including the construction of the fuel intake and the adjustment of the combustion chamber compression pressure. The KTT Sumber Sari, can use this capacity to support energy-independent cages.

Abstract

The Covid-19 pandemic which has had an impact on the education sector has forced educators to be more creative and innovative in preparing and implementing digital learning, without face-to-face meetings. Mutual Junior High School teachers already have these potentials, but they are not yet optimal. Some teachers already have digital materials in the form of learning media that use power points and videos. The problem that occurs, the materials owned by the teachers are not structured and there is no standard, even though they refer to the lesson plans. In addition, only a few teachers have used online evaluation. The purpose of this program is to help teachers prepare learning materials digitally in the form of PDF, PowerPoint and standardized videos. Programs carried out in the form of training to improve teacher skills. The results obtained were an increase in the number of digital learning materials in the form of PPT by 23%, online exam questions by 40%, and learning videos by 18%, all of which were used as digital learning media in E-learning Muhammadiyah (El-Mu).
