Biogas is a potential renewable energy source to meet energy needs, especially in remote areas that do not have access to electricity. The process of making biogas is carried out through anaerobic fermentation of organic materials such as vegetable waste, livestock manure and agricultural waste. This research aims to design a batch type biodigester that can produce biogas from a mixture of goat manure, chicken manure and vegetable waste. Biodigester is a reactor used to produce biogas. The stirred biodigester aims to mix the substrate evenly in the biodigester and prevent the formation of scum. The biodigester designed has a capacity of 120 liters with a stirring system to increase the efficiency of biogas production. The fermentation process was carried out for 21 days by monitoring parameters such as temperature, pH, Chemical Oxygen Demand (COD), and methane gas concentration (CH4). The results showed that the temperature and pH in the biodigester remained in optimal conditions for the activity of methanogenic microorganisms. The highest CH4 concentration measurement was recorded on day 20 at 60%, which indicates good biogas quality. In addition, the flame test on day 21 produced a blue flame, indicating a high CH4 content. The decrease in CH4 concentration at the end of the study was caused by the exhaustion of organic material. This research contributes to the development of efficient and environmentally friendly biodigester technology to produce biogas as a renewable energy source.

Lakor Island is one of the islands located in Southwest Maluku Regency (MBD). Lakor Island also has local livestock plasma nurfah that has been recognized by the Ministry of Agriculture, the local livestock plasma nurfah is Lakor goats. Lakor goats are one of the local goat groups whose base is on Lakor Island, Southwest Maluku Regency, Maluku Province, and have been determined through the Decree of the Minister of Agriculture Number 2912 / Kpts / OT.140 / 6/2011 dated June 17, 2011. Therefore, the livestock must be maintained and its population preserved so that it does not become extinct and run out, but the problem often faced by farmers on Lakor Island is the lack of feed in the dry season, to answer this problem in this community service will try to utilize agricultural waste, namely cassava skin as an alternative feed for goats on Lakor Island. The problem raised in this community service program is that the community does not utilize cassava skin waste as animal feed because they do not have knowledge about the utilization of cassava skin waste as animal feed. cassava peel is known as waste from cassava or cassava that has been peeled. cassava peel can be used as animal feed. the purpose of this community service is to utilize cassava peel waste as goat feed. Related to the main problems that have been mentioned, this community service program will offer a solution that is expected to be new information or knowledge to the community on Lakor Island about the use of cassava peel waste as animal feed. The hope of this community service program is that the community on Lakor Island will have new knowledge so that they can utilize cassava peel waste as animal feed, so that it can be an alternative feed that can be given to goats.

The Mergi Mulyo Farmers Group, Kadipiro Hamlet, Mungkid District, Magelang Regency is a farmer group that has a meat goat farming business. Coffee skins, which are plantation waste, have not been widely used as animal feed. The "Mergi Mulyo" livestock group is a partner in community service activities totaling 14 people. This activity aims to provide education regarding the use of coffee husks as animal feed and skills in making pelletized feed for goats. The methods used in this activity are surveys, outreach (lectures and discussions), and presentations. The results of his service show that breeders know that coffee skins can be used as goat feed. Apart from that, through direct practice, breeders have been able to independently make pellet-shaped feed from coffee skins.

This research aims to determine the physical and chemical, and antioxidant qualities of the combination of goat milk and black soy milk. This method used x+y+z formulation by combining goat milk and black soy milk which were the main ingredients in making ice cream. Ice cream was measured for physical quality (melting point and overrun); chemical (total solids and fat content, free fatty acids); and antioxidant qualities. The results showed that giving black soy milk can lower the melting point of ice cream due to the resulting low overrun. This was also supported by an increase in total solid ice cream. The highest ice cream fat content was in the 75:25 combination, namely 4.87%. The longer the storage of ice cream, the higher the increase in free fatty acids and the lower the antioxidant activity of ice cream. The conclusion of this study was the best quality to make ice cream from the combination of goat milk ice cream and black soy milk 75:25.
