Abstract

The quantity of raw water from springs, groundwaters, and rainwaters has been decreasing nowadays. This has mostly made river water to be used as the raw water to be treated for drinking water by PDAMs. However, in 2020, 52 rivers in Indonesia were polluted. Therefore, it is necessary to analyze the quality of the river water to ensure that the water conforms with the standards of the Indonesian Government Regulation Number 22 of 2021 (class 1). This study was done to study the water quality i.e. DO, TSS, and total coliform in 9 sampling points in Citarum, Cimanggu, Cibogo, Citonjong, Ciwayang, and Cigugur Rivers in West Java. Grab samples were collected and were analyzed in the laboratory. The results were then compared with the standards. DO in the Citarum River (= 3.66 mg/L) and Cimanggu River (= 3.64 mg/L) samples were below the standard which might result from the domestic waste generated by the housing settlements, schools, and hospital existed around the sampling points. Total coliform in the upstream of the Cibogo River sample was above the standard; which could be caused by the domestic waste produced by the housing settlements and the fishing area located around the sampling point.

Abstract

The manufacturing industry in this research was a polyester-producing manufacturing industry generating polyester chips and polyester staple fiber. The production process used raw materials and ancillary materials. Every raw material that was processed would produce products and byproducts in the hazardous and toxic waste (HTW) category; in the form of Wastewater Treatment Plant sludge, diethylene glycol, residue from the laboratory test, incinerator ash, spin finish oil, bottles of chemical solutions, and contaminated rags. This research aimed to evaluate the implementation of the HTW management for the key activities based on the relevant regulations to prevent harm to human health and the environment. The implementation of the HTWs management activities was observed on site. The observations were then compared with the regulations, and their conformity was scored using a Likert Scale. The results of the evaluations, covering 5 key activities of the packaging and containment, collection, storing, transportation, and symbolling and labelling, gave the percentage of 90%, 91.70%, 96%, 100%, and 85.20%, respectively. The average conformity of the HTWs management with the regulations was 93% and included in the very good category. Improvements have still to be done by this industry to ensure their HTW management operates properly by reducing their wastes using the suitable methods, such as through raw material substitution, process modification to a more efficient process, and the use of environmentally friendly technology.
