Utilization of Biogas Sources from Pig Waste as an Effort to Minimize Environmental Pollution

Livestock was one of the subsectors that play an important role in human resource development. One of the livestock commodities that had an important role as a source of animal protein was pigs. North Sulawesi had prospects in the development of pigs in terms of livestock resources and the availability of local consumers. The problem was that pig farms were developed in residential areas so that this condition had a negative impact on the environment of the community. This research was conducted with the aim of analyzing the potential for biogas production from pig waste. The research method used was a survey method with a case study approach to pig farming. The location of pig farms was determined by purposive sampling, namely pig farms managed in residential areas. Respondents were the Maesa pig farmer group in Tempok Village. Analysis of the data used was descriptive analysis through the analysis of biogas production potential.The results showed that the number of pigs in the pen was 13 tails, consisting of adult and grower phases, each of which was 4, and the starter was 5. The total weight of pigs was 753 kg which produces 56.59 kg of manure per day. The results of this study had the potential to produce 1.53 kg of gas per day. Based on the results of the study, it can be concluded that the biogas produced was beneficial for minimizing environmental pollution and substituting the use of LPG gas and firewood. Suggestions, biogas reactors need to be socialized to other farmers who develop pig farming businesses in residential areas and need government intervention to introduce biogas reactors because they require investment funds.
