Abstract

This study aims to measure the impact of planting activities using alternative planting media on the development of social-emotional character of Phase A students at SD Muhammadiyah 4 Malang City. The study used a quantitative approach with a quasi-experimental design. The research sample consisted of 130 grade 1 elementary school students involved in project-based activities. The research instruments in the form of questionnaires and structured observations were used to measure the development of aspects of cooperation, creativity, responsibility, and empathy. The results of the analysis showed that 5 students were in the "starting to develop" category, 30 students were in the "developing" category, and 95 students were in the "very developed" category. These findings indicate that project-based activities that utilize alternative planting media such as hydroton and hydrogel are effective in improving students' social-emotional character. This study emphasizes the importance of project-based learning in building students' character holistically.

Abstract

This research aims to analyze the impact of implementing the Project-Based Learning (PjBL) approach on enhancing fifth-grade students' understanding of plane figure perimeter concepts at SD Muhammadiyah 4 Malang. Employing a quantitative method with a pretest-posttest design without a control group, data were collected through written tests and project-based evaluations using an assessment rubric. The findings revealed a significant improvement in the students’ average posttest score compared to the pretest score, indicating that the PjBL approach effectively increased conceptual understanding (p < 0.05). Item analysis showed that the difficulty index fell within the moderate category (0.5–0.8), with most items demonstrating good discrimination power (above 0.3). The instrument's reliability, indicated by Cronbach’s Alpha, was 0.903, reflecting excellent internal consistency. Project assessment results recorded an average score of 91.2, categorized as "Very Good," which shows that students were able to creatively and collaboratively apply the perimeter concept to real-life contexts. These outcomes demonstrate that PjBL effectively promotes students' conceptual understanding while simultaneously supporting the development of essential 21st-century skills.
