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

This study aims to examine in depth the strategy to improve the effectiveness of science laboratory facilities and infrastructure management that can support quality practicum learning. Through literature review and literature review, this study analyzes various literature on the definition, function, role of science laboratory facilities and infrastructure management, strategies to improve the effectiveness of laboratory management, as well as inhibiting and supporting factors for the management of science laboratory facilities and infrastructure, and the impact on the quality of practicum learning. The results of the study indicate that the effectiveness of laboratory management is generally influenced by many factors, one of which is the availability of laboratory facilities and infrastructure that meet standards. Management of science education laboratory facilities and infrastructure is very important to support practicum activities in schools, with good management can increase the efficiency and effectiveness of practicums.

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.

Abstract

The fact that Indonesia is a maritime country with a land area of 1,910,931.32 km2 and ocean 3,544,743.9 km2. 64.97% of Indonesia's total area is water, but there are still many areas that lack clean water. Problems in some areas during the summer season also occur in the southern littoral region of Tulungagung. Potential seawater should be used for efforts to overcome water scarcity in local areas. We conducted preliminary research to purify seawater so it could become fresh and drinkable. A prototype model from previous researchers was modified and added a number of natural materials as filters. This natural material utilizes local Tulungagung resources, one of which is marble industry waste. The results showed that the prototype reduced the salinity of sea water from 23 "° to 0.167 "° or reached 97%.
