Abstract

The community service program, “Education and Learning of Chemical Reactions through Simple Science Experiments at SMA Negeri 2 Bengkulu Selatan,” aims to address the limitations of laboratory facilities in chemistry learning. This activity involved 37 students to enhance their understanding of chemistry concepts, practical skills, and interest in chemistry through experiments using natural materials and household waste. The implementation methods included the delivery of basic theory, demonstrations, pretests, and hands-on practice with three simple experiments: identification of vitamin C using iodine, making a lava lamp, and recycling used cooking oil into candles, followed by a posttest. Evaluation results from the pretest and posttest showed a significant improvement in students’ understanding. A total of 90.32% of students stated that they actively participated in the experiments and experienced a significant increase in their understanding of chemical reaction concepts after the practice. This program also strengthened the collaboration between the Chemistry Undergraduate Study Program, Faculty of Mathematics and Natural Sciences, University of Bengkulu, and the partner school through educational and interactive activities. The program outputs include a scientific publication in an ISSN-registered community service journal, an activity video, news publications on the Chemistry Study Program’s website and social media, and an intellectual property registration. Keywords: science experiment; chemical reaction; vitamin C; lava lamp; used cooking oil.

Abstract

Kepahiang Regency is one of the main Robusta coffee production centers in Bengkulu Province, rich in potential local spice resources such as ginger, lemongrass, and cinnamon. However, the Kaba Indah Lestari Women Farmers Group (KWT) in Bandung Jaya Village still faces challenges regarding limited technical knowledge and skills in technology-based coffee processing diversification. This community service project aimed to empower KWT Kaba Indah Lestari through training and mentoring on diversifying local Robusta coffee and herbal spices into sachet-packaged herbal coffee products. The implementation method consisted of five main stages: preparation and problem identification, counseling, practical training (raw material selection, roasting, grinding, and formulation blending), packaging-labeling assistance (using aluminum foil), and monitoring/evaluation. The results demonstrated a significant increase in the participants' knowledge and skills, as evidenced by a 20.83% improvement in average score from pretest (72) to posttest (87). The most substantial understanding gains were achieved in the indicators of diversification objectives and herbal coffee benefits (increased by 20 points). Through this program, participants gained the ability to independently execute the production process, creating marketable and hygienic herbal coffee sachets with enhanced value added and high competitiveness
