Abstract

The utilization of traditional herbal medicine among the inhabitants of Lombok is notably prevalent yet frequently hindered by a lack of comprehension regarding the efficacy of herbal remedies for specific ailments. Addressing this challenge, this study proposes the development of an Android application called "sopherbal", aimed at delivering personalized herbal plant recommendations via easily accessible mobile devices. Employing forward chaining methodology, the application identifies optimal herbal remedies based on ailment type, processing techniques, usage instructions, and recommended dosage and treatment duration. Notably, while effective in this context, the forward chaining approach entails certain trade-offs and hurdles. Previous research indicates that forward chaining facilitates accurate recommendation generation, and it may be constrained by its reliance on predefined rules and limited adaptability to complex, evolving scenarios. Despite these challenges, the ”sopherbal” application, featuring 50 Sasak medicinal plants curated for 15 common ailments, achieved an 86% validation rate, affirming its efficacy in bridging the gap between traditional herbal knowledge and modern healthcare needs.

Abstract

Chitosan (C6H11NO4)n is a chitin-derived polymer that has good biocompatibility, biodegradability, and bioabsorbability properties. This compound can be obtained from exoskeleton waste such as mangrove crabs and Windu prawn. This study aims to evaluate the comparison of chitosan levels based on the degree of deacetylation (%DD) from the waste shell, head, and leg of Windu prawn and mangrove crab shell waste obtained from the coastal area of Pasuruan, East Java. The extraction method was carried out through the stages of deproteinization, demineralization, and deacetylation using an alkaline solution, and then the characterization of molecular structure and %DD was carried out using an FTIR spectrophotometer. The results showed that chitosan from Windu prawn shell had the highest %DD of 73.0%, while mangrove crab shell and prawn head and leg showed lower values of 55.3% and 63.9%. This difference in %DD value indicates a variation in the success rate of deacetylation due to differences in biomaterial composition. The results of SEM testing showed that the use of the type of material in the manufacture of chitosan would affect the results of the surface morphology produced, where the Windu prawn shell produced the flattest surface.

Abstract

This research aims to develop an interactive PowerPoint-based learning media using Game-Based Learning (GBL) for junior high school students on environmental pollution. The method used is Research and Development (R&D) with a 4-D development model, which includes the stages of Define, Design, Develop, and Disseminate. However, the Disseminate stage was not implemented due to time constraints in the research. The media validation was conducted by three experts, comprising two science education professors and one junior high school science teacher, while the readability test was conducted with 18 seventh-grade students. The validation results showed the media's qualification level at 93%, placing it in the “almost perfect” category. Meanwhile, the readability test results averaged 94%, placing it in the “very good” category. The developed media are equipped with interactive features, including visual materials, animated videos, educational games, question-and-answer exercises, and GBL-based evaluation quizzes. Based on the validation results and readability tests, this media is deemed suitable for use in science instruction at the junior high school level.
