Abstract

Effective laboratory management is an important element in order to improve the quality of learning, especially in physics. This research is motivated by the need for a structured laboratory management system to ensure efficiency, safety, and sustainability of practicum activities. The purpose of this study was to examine the implementation of laboratory management at various levels of education as a real step in an effort to improve the quality of physics learning. The method used is descriptive qualitative, with data collection through literature study. The results showed that the implementation of laboratory management which includes aspects of planning, organizing, implementing, and evaluating has improved the quality of physics learning itself. Apart from the various supporting and inhibiting factors in it.

Abstract

Forests as critical ecosystems dominated by trees, face significant threats from extensive logging for infrastructure, manufacturing, and furniture industries, leading to deforestation and associated natural disasters such as floods and landslides. To address this, innovative solutions are needed to reduce reliance on forest wood. This study introduces an eco-friendly approach by developing recycled wood from organic solid waste, aligning with Sustainable Development Goals (SDGs), particularly Goal 9 (Industry, Innovation, and Infrastructure). Using an experimental method, recycled wood was produced from materials such as eggshells, sawdust, and marble waste. The process involved cleaning, drying, and pulverizing eggshells into powder, followed by oven-drying at 110°C for 45 minutes to achieve a maximum moisture content of 4%. The powder was mixed with a 60:40 polymer matrix and waste powder, with additional fillers like wood powder and marble waste, and molded into composite materials. Mechanical tests (tensile, flexural, compressive, water absorption, and density) revealed that natural fibers, such as coconut husk, enhanced mechanical strength, though water absorption remained high. The composite’s density (0.41–0.52 g/cm³) complied with SNI 03-2102-2006 standards for particleboard. This innovation not only mitigates deforestation but also fosters sustainable industry practices and economic opportunities through accessible technology, supporting equitable and sustainable development for future generations.
