Abstract

Problem-solving skills are an essential aspect that learners must have to deal with complex problems in real life. However, various studies show that students in Indonesia still have a low level of ability in this aspect. This study aims to measure the improvement of problem-solving skills through the application of Problem-Based Learning (PBL) based on Socio-Scientific Issues (SSI) on the topic of environmental change. This study uses a pre-experimental method with a one-group pretest-posttest design involving 34 students of class XI MIPA 1 at SMAN 1 Banjarmasin for the 2025/2026 school year. Sample selection was carried out by total sampling technique. The post-test results showed that the students' problem-solving skills were in the good category, with an average of 83.15%. MANOVA's analysis produced a significance value of 0.000 (< 0.05) which confirms that SSI-based PBL has a significant influence on improving problem-solving skills while fostering students' awareness of environmental conservation efforts. The findings of this research are expected to be a practical guide for educators in designing learning that is able to foster problem-solving skills as one of the competencies of the 21st century.

Abstract

Traditional food processing practices often contain implicit scientific knowledge that can be systematically analyzed and explained using modern science. This study examines the scientific knowledge embedded in the traditional preparation of Wadi, a fermented fish product of the Dayak and Banjar communities. The research aims to identify and describe forms of scientific knowledge represented in each stage of the Wadi-making process. This study employed a qualitative descriptive method using documentation analysis. Data were collected from selected written and visual sources that clearly describe the stages of Wadi production. The data were analyzed by mapping traditional practices to scientific concepts in food science. The results indicate that the preparation of Wadi embodies multiple forms of scientific knowledge, including osmosis in the salting process, salt-based preservation through microbial inhibition, lactic acid fermentation, moisture control, and biochemical transformations such as protein hydrolysis. These findings demonstrate that traditional culinary practices are not merely cultural activities but also reflect systematic scientific knowledge consistent with principles of microbiology, biochemistry, and food preservation. In conclusion, the scientific knowledge identified in the making of Wadi has strong potential to support contextual and culturally relevant science learning by connecting everyday practices with formal scientific concepts.
