Abstract

Waste management remains a critical issue related to environmental health. Insufficient knowledge in waste management contributes to environmental degradation, including soil, water, and air pollution, and serves as a potential source of diseases. This community service initiative aimed to implement the "Benderang Sentosa" Waste Management Program to enhance community knowledge of waste management practices. The program involved health education and training sessions conducted three times over three weeks. A total of 60 school-age children and 50 health cadres participated. Community knowledge was assessed using a pre-developed questionnaire. Descriptive data were analyzed to compare pre- and post-intervention results. The main result shows that the knowledge level of health cadres about waste management increased by 76%. Similarly, 75% of school-age children demonstrated a significant improvement in their understanding of waste management. The "Benderang Sentosa" Waste Management Program effectively increased community knowledge, contributing to better waste management practices and supporting the goal of a healthier environment.

Abstract

The textile industry, particularly the batik sector, significantly contributes to the Gross Domestic Product (GDP) of East Java Province. However, the batik dyeing process, which uses synthetic dyes like remazol, rapid, and naphthol, causes environmental issues due to the non-biodegradable nature of these dyes, leading to environmental pollution such as an increase in color levels in water bodies. This research investigated using activated sugarcane bagasse with KOH and HCl in batch adsorption systems as an alternative method. It compared the color efficiency removal in batik wastewater with variation biosorbent mass, contact time, and activator type. The study found that the highest percentage removal of dye substances was achieved with the KOH-activated biosorbent, reaching 69.46%, and the HCl-activated biosorbent demonstrated a 60.98% removal efficiency with a mass variation of 0.4 grams and a contact time of 30 minutes. Statistical analysis using multiple linear regression showed that independent variables (biosorbent mass, contact time, and activator) significantly affect the dependent variable (color removal efficiency) simultaneously. In the partial test, the independent variables of biosorbent mass and type of activator significantly affect color removal efficiency, but contact time does not significantly affect color removal efficiency.
