Abstract

The low levels of scientific literacy and science process skills among Indonesian students necessitate innovative approaches to learning. This study aimed to analyze the impact of using Problem-Based Learning (PBL) e-modules, incorporating local wisdom, on improving students' scientific literacy and science process skills. A systematic literature review (SLR) methodology was employed. Literature searches used relevant keywords in electronic databases such as Scopus, Web of Science, ERIC, and Google Scholar. The identified articles were screened based on inclusion and exclusion criteria, and their quality was assessed. Relevant data were extracted and analyzed both qualitatively and quantitatively. The study results indicate that PBL e-modules incorporating local wisdom effectively enhance students' scientific literacy and science process skills. Improvements were observed in concept understanding, critical thinking abilities, problem-solving skills, creativity, and learning motivation. Factors influencing the effectiveness of the e-modules include the quality of their design, the role of the teacher, and the learning context. This study recommends the broader development and implementation of such e-modules, teacher training in their use, and further research on the long-term impact of these modules on students' knowledge and skill retention.

Abstract

This research and development study aimed to produce learning materials based on a generative model assisted by PhET simulations to enhance students' critical thinking skills. The 4D development model (Define, Design, Develop, Disseminate) was employed. The developed products included a syllabus, lesson plans (RPP), teaching materials, student worksheets (LKPD), and a critical thinking skills assessment instrument. The validity of the products was evaluated by six validators using a Likert scale, practicality was assessed through student response sheets, and effectiveness was measured by the improvement in pretest-posttest scores using the N-Gain test. The results showed that the developed learning materials were highly valid (89.14%) and reliable (94.00%) based on validator assessments, and practical (72%) based on student responses. However, the improvement in students' critical thinking skills was moderate (N-Gain 0.43), indicating less than optimal effectiveness of the materials.

Abstract

Productivity of onion in Bima, West Nusa Tenggara (NTB), caused by rain and attacks from pests, has decreased significantly. One of the pests that often attack onion plants is armyworm (Spodoptera exigua Hubner) which causes 100% damage. To prevent damage, farmers use chemical pesticides to stop armyworm (Spodoptera exigua Hubner) attacks. The use of chemical pesticides has many negative impacts both in terms of the environment and health. To resolve this problem, utilize natural pesticides. Natural pesticides don’t have residual effects and are safe for health. The purpose of this study was to know the effect of natural pesticides garlic and liquid soap against the mortality of armyworms. The methods used are experimental research and a quantitative approach. The result of this study obtained the highest armyworm mortality at 9 days of immersion of 100% and the longer the immersion was carried out the higher the mortality rate of armyworm. Based on the analysis of One Way ANOVA, there was an effect of soaking time of natural pesticides against the mortality of armyworms with a significant value of 0.046.
