Abstract

The issue of waste, especially plastic waste, is a very serious environmental concern in Indonesia. Plastic waste is difficult to decompose naturally and has the potential to pollute soil, water, and air, thus negatively impacting human health and ecosystems. One solution that can be implemented to reduce this impact is the 3R (Reduce, Reuse, Recycle) waste management concept, particularly through the ecobrick method. This study aims to implement the ecobrick method as an effort to manage plastic waste in a school setting, involving student participation at SDN 13 Mataram, Selaparang District, Mataram City, West Nusa Tenggara. The research method consists of three stages: planning, implementation, and reflection. In the planning stage, students were introduced to how to create fences using ecobricks. The implementation stage involved students in collecting, sorting, and tightly packing plastic waste into used bottles with the help of wooden sticks. In the reflection stage, the completed ecobricks were used as fencing for a medicinal plant garden at the school. The results showed that students were very enthusiastic and actively engaged throughout the process. In addition to reducing the amount of plastic waste, this activity also raised students’ awareness about the importance of environmental preservation. The ecobrick method proved effective as a hands-on learning tool and can serve as an innovative, educational, and practical waste management strategy for elementary schools.

Abstract

Science process skills are essential for students to analyze information and solve problems effectively. This study aims to determine the effect of the Project-Based Learning (PJBL) model combined with simple science experiments on the science process skills of fifth-grade elementary school students. This study employed a quantitative approach using a quasi-experimental design with the Nonequivalent Control Group Design. The research subjects consisted of an experimental class treated using the PJBL model with simple science experiments and a control class using a conventional learning model. Data collection techniques employed a multiple-choice test on science process skills that had been tested for validity and reliability. The results showed a significant difference in students’ science process skills between the two classes, indicating that Ha was accepted and H0 was rejected. The highest improvement occurred in the classifying indicator, while the lowest improvement was found in the observing indicator. Therefore, the PJBL model combined with simple science experiments had a positive effect on students’ science process skills in the IPAS subject, particularly on the topic “What Are Magnets and Why Were They Created?” for fifth-grade students at SDN 1 Midang, with a p-value of 0.008 < 0.05.
