Abstract

Cow dung is one of the wastes that can disturb the environment. The volume that continues to increase without handling can cause disease, especially during the rainy season. So seeing these conditions, socialization was carried out to increase the knowledge and skills of the community in processing cow dung waste into biogas. The method or activity steps are the preparation, socialization, and evaluation stages. The results of the activity showed that the socialization activity with the theme of utilizing cow manure into biogas received a good response from all circles of society, especially members who were members of the human-informed cattle group and from the village of Ranjok itself. The socialization activity was attended by 23 people who enthusiastically participated in the activity until the end. The results of the evaluation by conducting interviews that the community is ready to be involved in biogas production training activities by applying biodigester technology. In addition, with the knowledge and skills that the community has independently, they can process cattle waste into biogas so that the volume of waste can be reduced and biogas can be utilized.

Abstract

One alternative energy source for making organic waste which can be renewed is pineapple waste and tofu waste. Biogas produced from these two materials is environmentally friendly so it does not disturb the environment. The purpose of this research was to determine the changes in temperature and pH that occurred during the formation of pressure and volume of biogas. The method used in this study was an experimental method using a completely randomized design (CRD). There are 4 treatments in this study, namely T1: pineapple waste; T2 : tofu liquid waste; T3 : addition of tofu solid waste; and T4 : addition of tofu liquid waste and tofu solid waste. The measurement results were then analyzed using analysis of variance (ANOVA). If significantly different results were found, a further test was carried out with BNJ. The results showed that the addition of tofu waste significantly affected the temperature, pH, pressure and volume of bioga. The average temperature for each treatment was 28oC, while the highest pH was 8.55. The highest pressure calculation results were found at T4 of 109.42 N/m2, while for the highest volume it was found at T4 of 0.000016642m3. Based on the description above, it can be concluded that the addition of tofu waste has a significant effect on the formation of biogas
