Abstract

The Community Service Activities Conducted in Batuan Village, Sukawati, and Gianyar-Bali Aim to Increase Knowledge and Skills of Family Welfare Empowerment (FWE) In Managing Composting to Become Fertilizer Products That Have Economic Value. FWE has become a leader in waste management at the household level. The methods used include observation, counseling or education, direct practice, monitoring, and evaluation. Based on the results, 100% of FWE can use tools for the composting process to produce organic compost with economic value, 100% understand the use of compost, and 100% are skilled in using compost as quality organic compost. FWE in Batuan Village, after receiving socialization and training, commits to sorting waste and making compost into organic fertilizer with economic value.

Abstract

Making bioethanol from papaya fruit is done through a fermentation process. Yield is influenced by the duration of fermentation and the mass variation of the bread yeast Saccharomyces cerevisiae. The pH treatment and initial sugar content of the substrate were also tested before the addition of glucose. This study aims to examine the effect of yeast concentration and fermentation time on the amount of bioethanol produced from papaya fruit in the manufacture of bioethanol. The maximum concentration of bioethanol produced by a concentration of 2% S. cerevisiae is 5.44% due to the addition of yeast, according to the number of nutrients in the sample. In order of concentration from high to low, it is 2% > 4% > 3% > 5% > 1%. While the maximum pH value of 4.9 with a concentration of 2% was obtained in ethanol production by Saccharomyces cerevisiae.

Abstract

This literature study research aims to find the appropriate yeast dose and fermentation time to process papaya skin waste into bioethanol by utilizing Saccharomyces cerevisiae yeast. Papaya skin waste is one of the biomass that is quite abundant and contains high sugar content so it can be used as raw material for making bioethanol. The data collection method was carried out through online searches of scientific journals related to the potential of papaya waste, fermentation, bioethanol production, bioethanol manufacturing techniques, yeast types and yeast doses, and bioethanol content. As a result, get fermentation for making bioethanol efficiently using a yeast dose of 0.3% and the fastest fermentation time of 3 days
