Abstract

Online learning was an option during the COVID-19 pandemic, so teachers cannot directly see the activities of their students. Therefore, exciting teaching materials were needed and facilitate independent learning for students. Based on this, an electronic LKPD for trigonometric comparisons in ethnomathematical-based right triangles was developed in the cultural heritage buildings of Banjarmasin City. The purpose of this research was to produce valid LKPD. This study uses the research and development (RnD) method with a 4D model but was carried out only up to three stages: define, design, and develop. The results of material validation based on aspects: format, content, language, and culture were declared valid. Meanwhile, based on media validation, which was seen from the elements: design and ease of operation are also categorized as accurate, so an ethnomathematics-based electronic LKPD was obtained in a valid Banjarmasin City cultural heritage building. Electronic LKPD still needs to be tested on students to be used in the learning process.Keyword: Electronic student worksheets, trigonometric comparisons, ethnomathematics, cultural heritage buildings.

Abstract

Adolescents are an age group vulnerable to risky behaviors such as smoking and staying up late, which can negatively affect both physical and psychological health. Limited knowledge about the dangers of nicotine and sleep pattern disturbances is one of the factors contributing to the high prevalence of these behaviors. This community service activity aimed to implement the GUDANG GARAM program (Gerakan Ubah Diri, Akhiri Nikotin dan Begadang, Gapai Raga Aman dan Menyehatkan) through health education to improve adolescents’ knowledge in Sungai Asam Village. The program applied an educational approach through health counseling using posters and leaflets, accompanied by pretest and posttest evaluations to measure changes in participants’ knowledge. A total of 26 adolescents participated in all stages of the program. The evaluation results showed an increase in the average knowledge score from 6.73 before the intervention to 8.42 after the educational session, indicating improved understanding regarding the dangers of nicotine and staying up late. In addition, the activity was conducted interactively through discussions and question-and-answer sessions, which enhanced adolescent participation in the learning process. The implementation of the GUDANG GARAM program was proven to improve adolescent health literacy and has the potential to serve as a promotive and preventive strategy in fostering healthy lifestyle behaviors within the community. This program is recommended to be implemented sustainably with support from families and the community to optimize behavioral change outcomes.
