Abstract

The use of synthetic soaps containing harmful ingredients has driven consumers toward natural soap alternatives. Transparent soap offers the advantage of producing a softer lather and containing moisturizing agents that help prevent dry skin, making the development of transparent soaps with natural active ingredients essential for maintaining skin health and beauty. This study aimed to develop a transparent soap formulated with bangkal wood bark (Nauclea subdita) extract, a native plant of South Kalimantan rich in secondary metabolites such as alkaloids, flavonoids, polyphenols, and saponins. Previous studies have reported that these compounds possess natural antioxidant and sunscreen properties, as well as anti-inflammatory, antiplasmodial, antipyretic, and antimicrobial potentials. The methodology included reflux extraction using 96% ethanol, soap formulation through saponification, and comprehensive quality evaluation. Tests conducted included measurements of water content, pH, chloride content, ethanol-insoluble matter, free fatty acids/alkali, total fatty matter, unsaponified fat, foam stability, and organoleptic properties. The results showed that the transparent soaps with bangkal wood bark extract met the SNI 3532:2021 standards for water content, pH, ethanol insoluble matter, chloride content, foam stability, and total fatty matter across all extract concentrations. However, soap D (6 grams extract) exceeded the acceptable limit for free fatty acids. Organoleptic evaluation indicated that all formulations were well accepted by the panelists. Therefore, the bangkal wood bark extract demonstrates strong potential as a natural active ingredient for developing transparent soap formulations that meet quality standards.

Abstract

High school adolescents are a vulnerable group to exposure to addictive substances due to social and academic pressures, thus requiring literacy-based preventive interventions. This community service program aimed to strengthen students’ literacy regarding the hazards of addictive substances at SMA Negeri 2 Banjarbaru through a chemical literacy-based approach, delivered using educational infographics and participatory learning activities. The program was implemented in a single integrated session consisting of a pre-test, delivery of materials using infographic media accompanied by interactive mini quizzes via Quizizz, a question-and-answer session, and a post-test. A total of 36 students participated in the activity, comprising 12 representatives from each grade level (grades X, XI, and XII). Evaluation results showed an improvement in students’ understanding of addictive substances, as indicated by an increase in the average pre-test score of 66.4 (median 70.0 with score ranged from 30.0 to 100.0) to an average post-test score of 87.5 (median 90.0 with score ranged from 60.0 to 100.0), representing an increase of 21.1 points (31.8%). In addition to quantitative evaluation, brief non-formal interviews with students conducted during and after the activity indicated early signs of changes in students perspectives, particularly in their awareness of adopting healthier and non-addictive coping mechanisms when dealing with academic stress. These findings suggest that infographic-based educational approaches combined with interactive activities are effective in enhancing literacy on the hazards of addictive substances as a foundation for primary prevention among adolescents. To support program sustainability, the educational materials were provided to the school in both printed and digital formats for use in guidance and counseling services as well as school health programs.
