Abstract

Soapnuts or commonly called soapnuts are plants with seeds used in traditional detergents, consisting of 75% flesh and 25% seeds. The advantage of this plant is that it can be used as a raw material for making detergent. The method used in this community service activity is in collaboration with the PKK group in Pekon Kubu Perahu, Balik Bukit District, West Lampung Regency, which consists of 20 members. This activity is a socialization about the dangers of conventional soap, the active compound content of soapnuts, training in manufacturing techniques and the production process of processing soapnuts into liquid soap. The result of this service is the processing of soapnuts into liquid laundry soap, providing a positive impact on PKK mothers in Pekon Kubu Perahu, namely they can make their own environmentally friendly and safe laundry soap. Soapnuts are plants that contain chemical compounds with bioactivity as antibacterials. The conclusion of this service activity is that through socialization and direct practice, PKK mothers can learn the benefits of using soapnuts in making economical and environmentally friendly liquid laundry soap.

Abstract

Microplastics are durable and contain harmful compounds that can be absorbed into the soil and enter the food chain, posing a risk to human health and the environment. One of the efforts to reduce its impact is to utilize bacteria as biodegradation agents. The purpose of this study was to isolate and characterize microplastic degrading bacteria from three landfills in Lampung Province, and determine their degradation rate. The research method used a quantitative descriptive approach, including the isolation stage with the pouring technique, degradation tests using Polystyrene, Polyethylene Terepthalate, and Polyethylene measuring 1x1 cm and identification using Vitek-2. The results of the study from nine bacterial isolates that were successfully purified, three of them showed the highest ability to degrade. The weight reduction result on PS plastic sample was 22.2% by Bacillus circulans, PET sample was 15.9% by Pandoraea spp. and PE sample was 36.2% by Pseudomonas aeruginosa bacteria.
