Abstract

This study aims to investigate the effect of sodium hypochlorite addition on the tensile strength of bioplastics derived from giant taro tuber starch (Alocasia macrorrhizos). The research employed an experimental method with variations in sodium hypochlorite addition of 10%, 20%, 30%, and 40%. Bioplastic samples were prepared through starch extraction, followed by mixing with sodium hypochlorite, glycerol, and water, and subsequently tested for tensile strength using a tensile testing machine. The results revealed that the highest tensile strength value, 1300 N/m², was achieved in the sample containing 40% sodium hypochlorite, satisfying the Indonesian National Standard (SNI). It is concluded that increasing the percentage of sodium hypochlorite positively affects the tensile strength of the resulting bioplastic.

Abstract

Abstract:  This community service activity involved a partner, namely the Preparatory Village of Benue. The objectives of this program were: 1) to conduct a socialization session about the Community Service Program (KKN) carried out by Universitas Muhammadiyah Mataram, with the aim of placing students in the Preparatory Village of Benue in the future; and 2) to assist in creating unique and attractive promotional videos and infographics related to the River Tubing tourist attraction at Kokok Babak, which could be distributed primarily through social media. The method used in this community service consisted of three stages: 1) preparation stage, 2) implementation stage, 3) implementation stage (note: this is repeated in the source), and 3) monitoring and evaluation. Based on the results of the socialization and implementation, it can be concluded that: 1) 90% of the staff in the Preparatory Village of Benue have understood the KKN program organized by Universitas Muhammadiyah Mataram, which opens the opportunity for future student placements; and 2) 90% of the river tubing tourist site has been recorded, and the promotional videos have been created in an engaging and creative manner and successfully disseminated through Facebook and YouTube.Abstrak: Kegiatan pengabdian ini memiliki mitra yaitu Desa Persiapan Benue.
