Abstract

Biogas is renewable energy consisting of 55-65% methane, 35-55% carbon dioxide, and 0.1-3% hydrogen sulfide. advantage of biogas lies in its abundant availability. Biogas is produced anaerobically using organic raw materials mediated by microbes. The biogas production process consists of four stages, namely hydrolysis, acetogenesis, and methanogenesis. supporting materials used are 150 liters and 55 liters HDPE drums, ½ in the pipe, ¾ in the pipe, ½ in T the pipe connection, ½ in the pipe elbow, ½ in the pipe valve, ¾ in thread socket, 1 bar pressure gauge, 1 bimetal thermometer required, water pump. The tools used include pH meters and gas detectors. CSTR-type digester uses a pump as the circulation system. The advantages of using a circulation pump are maintaining operating temperature, increasing material contact, inhibiting sedimentation, and reducing fermentation time. In the design of the Digester tool, a gal holder is also used as a container for the biogas produced by the Digester during operation, the result of variations in circulation which are carried out every 4 days, and the addition of raw materials every day is 3 liters/day, 1.5 liters of cow dung and 1.5 liters of tofu liquid waste resulted in variation 0 circulations 41% methane, pressure 0.1, COD value 13,200, variation 30 circulations 52% methane, pressure 0.16, COD value 11,792, variation 60 circulations 55% methane, pressure 0 .18, and a COD value of 10,560, and at variation 90 circulations 58% methane is produced, a pressure of 0.19, and a COD value of 7,040.

Abstract

West Sumatra has a high potential of coconut resources with most of it being processed for copra products. The pandemic situation in recent years has caused the price of copra products to fluctuate, so an alternative coconut processing is needed. Virgin Coconut Oil (VCO) is an alternative coconut product that can increase economic value of coconut and is needed as a supplement that can strengthen the body's immune system during the Covid-19 pandemic. One of the efforts to train the community to be able to process coconut into VCO is to conduct training activities that are directly located in the coconut farmer cluster, which is carried out in Sungai Sirah Village, South Coast District, West Sumatra. This community service activity aims to increase the competence of farmers in the village so that they can process the coconut produced into VCO, hence help their economy when the price of copra drops. The stages of the activity start from socialization, presentation on production process, and continued with demonstrating how to make VCO. Participants were divided into several small groups where they could immediately practice how to make this VCO with the correct fermentation steps. After the manufacturing process is well understood, the next step was training of how to do packaging and marketing. Farmers were trained on how to package products in order to get good quality product and then trained to sell VCO through online shop such as Facebook, Instagram, Tokopedia, etc. This activity helps add more insight in terms of processing and marketing, in which participants increase their knowledge and competence to form the basis for entrepreneurship of coconut processed products.
