Abstract

Hazardous and toxic waste is the residual waste from any business or activity that contains hazardous and toxic materials. According to the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia No. P.56 of 2015, hospitals are categorized as healthcare facilities required to manage B3 waste. The importance of managing hazardous and toxic waste in hospitals is significant, as improper management can lead to various negative impacts.In the transportation of B3 waste, RSUD Pasaman Barat collaborates with PT. Andalas Bumi Lestari, conducting transport twice a month. The aim of this research is to calculate the emissions of CO₂, CH₄, and N₂O from the transportation activities occurring at the Temporary Storage Site (TPS) of RSUD Pasaman Barat. This study seeks to understand the impact of hazardous waste transportation on global warming at RSUD Pasaman Barat. This research employs a quantitative method to calculate emissions from the transportation activities of hazardous and toxic waste at RSUD Pasaman Barat.

Abstract

Padang City is a large city with an area of 694.96 km² and a population of 941,639 in 2018. The waste generated in 2018 amounted to 1,313,342.7 m³ (Padang City Environmental Agency, 2018). Landfills produce a type of liquid known as leachate. Leachate is a hazardous liquid generated from the decomposition of both organic and inorganic waste at the Final Disposal Site (TPA) of waste. This liquid contains high concentrations of organic, inorganic materials, and heavy metals that have the potential to contaminate groundwater, rivers, and surface water. This study aims to analyze the quality of leachate based on the Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) parameters as the main indicators of organic pollution. Samples were taken from the outlet pond of the Air Dingin TPA in Padang City, then brought to and tested at the Andalas University Water Laboratory. The results showed a COD value of 450.4 mg/L and a BOD value of 250 mg/L. These values far exceed the quality standards established in the Minister of Environment Regulation No. 59 of 2016 concerning Wastewater Quality Standards. This study indicates that leachate requires further management before being released into the environment.

Abstract

The Air Dingin Landfill (TPA) in Padang City is a major waste disposal site, with open burning and waste decomposition activities producing hazardous gas emissions. This study aims to analyze the concentrations of sulfur dioxide (SO₂) and carbon monoxide (CO) as air pollution parameters around the landfill. Sampling was conducted in the active area of the Air Dingin Landfill on May 19, 2025. Laboratory analysis compared the concentrations of SO₂ and CO to ambient air quality standards established by Government Regulation No. 22 of 2021. The results showed that the SO₂ concentration was 173 µg/m³ and CO was 4,170 µg/m³, both exceeding the established standards. These findings indicate the need for emission management and combustion activity control to minimize the impact of air pollution.

Abstract

Water is a basic human need in everyday life. Humans use water for daily needs such as drinking, bathing, washing, and so on. Poor quality air will result in a bad environment that will affect human health and safety .Sumber Agung Village has a population of 2,773 people based on infographic data from Sumber Agung Village, consisting of 895 heads of families, with details of 1,411 men and 1,362 women The water source in Sumber Agung Village is PAM water PAM water is an abbreviation of Drinking Water Company, which refers to clean water distributed by drinking water companies to the community through a network of pipes, and has gone through a series of processing processes to ensure its quality is safe and for consumption Experts), stated that PAM air comes from various sources such as rivers, lakes, or groundwater which then go through processing processes such as coagulation, flocculation, sedimentation, filtration, and disinfection before being distributed can be related to several important factors, such as the condition of the air source, the potential for contamination, and its impact on public health. This study aims to analyze the drinking water quality in Sumber Agung Village based on physical parameters. Color: Drinking water should be clear and colorless. Turbidity: Drinking water should not be cloudy, indicating the presence of suspended particles such as mud. Temperature: The ideal drinking water temperature is between 18°C and 22°C. Chemical parameters: pH: The acidity or alkalinity of drinking water should be in the range of 65-85. Biological parameters: Pathogenic bacteria: Drinking water should be free from harmful bacteria such as E. coli and Coliform, according to Health Regulation No. 2 of 2023 concerning Drinking Water Quality Standards.
