Abstract

This study explores the role of local wisdom in traditional herbal medicine processing among the Sasak community in Lombok, Indonesia. The focus is on the extraction techniques used by traditional healers (belian), especially their selection of specific woods for the heating process to preserve the stability of bioactive compounds. Using a qualitative descriptive method, data were collected through interviews, observations, and documentation involving experienced traditional practitioners. The findings show that belian possess inherited empirical knowledge that integrates technical, ecological, and spiritual considerations. This includes selecting herbal plants based on environmental quality, using sustainable harvesting methods, and applying low-heat boiling techniques to prevent degradation of sensitive compounds such as flavonoids and alkaloids. Additionally, spiritual rituals and intuitive practices accompany the preparation process, reflecting a holistic healing philosophy. The study reveals that these traditional methods align with modern principles of sustainable and effective herbal extraction. The integration of traditional knowledge with scientific understanding presents an opportunity to develop culturally rooted, low-cost, and environmentally friendly healthcare solutions. The preservation and documentation of this local wisdom are essential for future generations and the advancement of ethnopharmacological science.

Abstract

This study explores the formulation and quality evaluation of solid soap made from recycled cooking oil enriched with fermented Ananas comosus (pineapple) peel extract. Three formulations were prepared using varying concentrations of pineapple peel eco-enzyme, while maintaining consistent proportions of palm sugar and water. The soap samples underwent physicochemical characterization in accordance with Indonesian National Standards (SNI). Results showed that all formulations had pH values within the acceptable range. Moisture content met regulatory limits in two formulations. All samples exhibited good foam stability, although the free fatty acid content exceeded permissible levels, likely due to extended hydrolysis during processing. Organoleptic assessment revealed uniform cream coloration, a characteristic aroma resembling soybean milk that decreased with higher eco-enzyme concentrations, and increased astringency corresponding to the concentration of pineapple extract. The soap maintained a solid texture with varying degrees of tackiness. This research demonstrates the potential for converting household waste into value-added products, while highlighting the need for further optimization to ensure compliance with commercial quality standards.

Abstract

Research on student responses and the challenges of implementing virtual laboratories in qualitative cation analysis practicums within vocational pharmacy education remains limited. This study aims to explore student responses to the use of virtual laboratories as an alternative learning tool and to identify the challenges faced during its implementation. A qualitative approach with a case study method was employed. Data were collected through questionnaires and classroom observations during the learning process. The participants were 41 Grade XII students of the Pharmacy Program at SMK Galang Insan Mandiri Binjai, who engaged in virtual laboratory-based learning for qualitative cation analysis. The results indicate that virtual laboratories enhance student engagement and comprehension of the subject matter. Students responded positively to the use of virtual labs, reporting increased motivation and interest in developing technology-related skills. However, challenges such as limited digital literacy and infrastructure issues were also identified. The study suggests that virtual laboratories should be complemented with hands-on practicum sessions to provide a balanced and realistic learning experience. These findings offer valuable insights into the potential and limitations of virtual laboratory implementation in vocational pharmacy education.
