Abstract

This study developed a Discovery Learning model with a Meaningful Learning approach to improve students' critical thinking skills in Economics at SMAN 2 Tulang Bawang Udik. The study used the ADDIE model and produced a conceptual model, lesson plans, student worksheets, and HOTS assessment instruments. Expert validation results showed that the products were feasible, practicality tests obtained a very practical category, and effectiveness tests with a Nonequivalent Control Group design showed that the critical thinking of students in the experimental class was higher than that of the control class. These results confirm that this learning model is feasible, practical, and effective, and can be a guide for teachers for active, contextual, and high-level thinking skills-oriented learning. Additionally, the integration of Discovery Learning and Meaningful Learning provides a structured and student-centered learning process that encourages learners to construct knowledge independently while connecting concepts to real-life contexts. The resulting learning tools also support teachers in implementing systematic instruction that fosters student engagement and deeper understanding. Overall, the developed model contributes to improving instructional quality in Economics education and offers an innovative alternative for enhancing students’ cognitive abilities, particularly in critical thinking.

Abstract

This study aims to determine the impact of replacing halogen lights with LED lights on two-wheeled vehicles, focusing on energy efficiency, light brightness levels, and operational temperatures of the lights to support road safety in areas with minimal road lighting, as well as on adjusting the light distribution of the applied LED lights. The method used was an experiment conducted on variables for which data were unavailable, necessitating manipulation of the research object. The experiment was conducted using a Honda Supra 125 FI motorcycle, with measurements of light intensity (lux), power consumption (watts), battery current (V), electric current (A), and operating temperature (°C). The known impact became a reference for regulating LED light distribution. The test shows that applying a barrier plate design to LED lights can provide focused lighting through its light distribution patterns. The application of the baffle plate design to LED lights provided focused lighting through its light distribution patterns. The use of LED lights provided a slightly higher intensity (6.4%) and an energy consumption efficiency 60% higher, with a reduction in operating temperature of 64%. The application results show that the light control plate successfully forms a bright-dark cut-off, with a uniform light distribution and consistent light intensity of 1854 lux. This indicates that the tested LED lamp maintains stable lighting performance without a decrease in brightness.

Abstract

The waste problem caused by low public awareness and limited waste management systems remains a crucial issue that leads to environmental degradation. This community service program was initiated as a solution to address the accumulation of unmanaged waste through the implementation of the 3R (Reduce, Reuse, Recycle) concept. Its objectives are to build community self-reliance in waste management, improve environmental quality, and empower local economic potential. Through outreach activities and intensive training, the program was implemented in Kuta Bangun Village. The results indicate the successful implementation of the program, marked by increased understanding and awareness among residents in applying proper waste management practices. In addition to raising awareness, this initiative also succeeded in establishing an independent waste-bank management group as a concrete step toward sustainability. The waste bank not only functions as a center for collecting and sorting waste but also serves as a driving force for the circular economy by converting recyclable inorganic waste into an additional source of income for residents. This success indicates that education- based interventions and community empowerment are effective in transforming behavior and creating a socially and economically sustainable waste management system at the village level.
