Abstract

This study aims to describe the effectiveness of the SiMaYang learning model, based on the ethoscience of turmeric and tamarind herbal medicine, in the context of acid-base conceptsto enhance students’ critical thinking skills. This study employed a quasi-experimental design with a pretest-posttest control group. The study population consists of 11th-grade students at State High School 16 Bandar Lampung for the 2026/2027 academic year. Sampling was conducted using cluster random sampling, resulting in Class XI.4 as the experimental class and Class XI.5 as the control class. The data analysis techniques in this study used a two-sample t-test and an effect size test.The results showed that the mean n-gain for critical thinking skills in the experimental classmet the “high” criterion, and there was a significant difference between the experimental and control classes. The effect size test yielded a value of 0.98, meeting the “large” criterion, indicating that 98% of the improvement in students’ critical thinking skills was attributed to the SiMaYang learning model based on the traditional medicine of turmeric and tamarind. Based on the results of the analysis conducted, it can be concluded that SiMaYang learning based on the ethoscience of turmeric and tamarind herbal medicine is effective in improving students’ critical thinking skills regarding acid-base concepts.

Abstract

This study aims to describe the effectiveness of SiMaYang-based ethoscience instruction on acids and bases in improving students’ science process skills. This study used two classes—an experimental class and a control class selected from three 11th-grade science classes at State High School 16 in Bandar Lampung for the 2025/2026 academic year, using cluster random sampling. This study employed a pretest-posttest control group design. The results showed that the average n-Gain for students’ science process skills in the experimental class was 0.71, meeting the “high” criterion, while in the control class it was 0.55, meeting the “moderate” criterion. The effect size test yielded a value of 0.98, classified as “large,” indicating that 98%. Based on the analysis, it can be concluded that the ethoscience-based SiMaYang learning model is effective in improving students’ science process skills in the acids and bases unit.
