Abstract

Diseases can be spread directly or indirectly via unprocessed garbage. Garbage management is crucial if we want to reduce the negative effects that waste has on our health. The community of Pantai Gemi lacks waste-processing infrastructure. The Sanitation Service's inaccessible trash transportation system, which forces people to process waste on their own, is the root of this issue. One significant effort that can be made is to educate the community. This study sought to ascertain how public perception has changed as well as how much less inorganic and organic trash was being produced as a result of the extension intervention. A pre-test-post-test design with one group is used in this kind of research. All of the 2,179 family heads who make up the study's population make up its sample of 30 families. Seven respondents, according to data on changes in respondents' knowledge, report changes in their knowledge of waste management. The results of the normality test demonstrate the homogeneity of the waste generation statistics. The Dependent Sample T-Test method was used to examine waste generation. The analysis of the volume of inorganic waste yielded t = 0.00<0.05, indicating that intervention has an effect on decreasing the volume of inorganic waste in Pantai Gemi Village. The analysis of the weight loss of organic waste yielded t = 0.00<0.05, indicating that intervention has an effect on weight loss of organic waste in Pantai Gemi Village. Residents of Pantai Gemi Village should be given advice by the Department of Cleanliness and the Environment. For the Gemi Beach Village Apparatus to be able to connect the neighborhood's trash management efforts with relevant organizations. For Pantai Gemi Village inhabitants to become accustomed to and learn more about handling waste on their own.

Abstract

Manganese (Mn) is a heavy metal that naturally exists in the environment and can contaminate drinking water sources through anthropogenic activities, particularly in agricultural areas. Long-term exposure to Mn levels above safe limits can lead to neurological disorders in humans. This study aims to analyze the risk management of manganese contamination in drinking water sources in Langkat District, North Sumatra. A cross-sectional study was conducted on 8 samples of well water and 209 respondents. Data collection included water sampling and neurological symptom assessment using the Q18 questionnaire. Risk analysis was carried out based on concentration exposure, body weight, and daily water intake to calculate the Risk Quotien (RQ). Manganese concentrations in water ranged from 0.991 mg/L–2.809 mg/L, exceeding the Indonesian Ministry of Health threshold of 0.1 mg/L. Six respondents experienced numbness, and four experienced palpitations. Risk management analysis showed a safe body weight at 36.26–141.81 kg, the safe length of residence ranged at 23.01–58.72 years, and safe Mn concentration at 0.62–2.78 mg/L. This study provides important scientific evidence for developing risk management strategies for manganese contamination in drinking water to prevent neurological issues in Langkat Regency. Recommendations were given to improve water quality monitoring and community health education.
