Abstract

Bengkulu Province is one of the areas in Indonesia that often experiences landslides, especially during the rainy season. Therefore it is necessary to have landslide disaster mitigation education for students. The purpose of this study was to design integrated natural science learning for landslide relief. The method used is qualitative with a descriptive approach. Data collection through teacher interviews, syllabus analysis, and literature study. Then the data obtained were analyzed to obtain a learning design. The results of this study are science learning designs that are integrated with landslide disaster mitigation. The concept of IPA that can be inserted is motion, namely Newton's law, where landslides occur due to movement in the ground. The learning process can be carried out using the STEM approach with the PJBL (Project Based Learning) model. So that this learning design will be contextual because it relates to everyday life. This learning design will later make working in groups in designing simple student technology as a response to landslide disasters. It is hoped that after learning students will more easily understand the concept of science because it is integrated with landslide disasters which are close to their lives and can apply it in everyday life.

Abstract

Background: The integration of environmental issues into junior high school science learning remains limited, reducing opportunities for students to develop scientific literacy through contextual, practical activities. Although science literacy-oriented modules have been developed, practicum modules that focus on converting leachate into liquid organic fertilizer as a contextual learning resource for scientific literacy are still rarely reported.Aim: This investigation sought to create and assess the practicability of a leachate-processing practicum module intended to support scientific literacy among students in junior high school. Methods: The investigation utilized a research and development methodology employing the 4D model, which encompasses the Define, Design, and Develop phases. A restricted implementation was carried out utilizing a one-group pretest–posttest framework. Validation involved four experts. Participants were Grade IX students: 27 completed the response questionnaire and 24 the scientific literacy test, reflecting attendance during the respective data collection sessions. Data were examined utilizing Aiken’s V, descriptive statistics, N-gain, and a paired-sample t-test.Results: The module demonstrated high validity with an Aiken’s V score of 0.961. Student responses exceeded 90%, indicating very positive perceptions of the module. Scientific literacy scores demonstrated an increase from a mean pretest score of 59.17 to a mean posttest score of 89.58, accompanied by an average N-gain of 0.79, which is classified within the high category. Significant differences were found between pretest and posttest scores (p < 0.001).Conclusion: The developed practicum module is feasible for use in contextual science learning and demonstrates promising effects on students’ scientific literacy in a limited implementation setting.
