Perhitungan Beban Pencemaran Air Sungai Cibabat Kota Cimahi Provinsi Jawa Barat

Abstract

The lack of domestic wastewater management services in the Cibabat River Basin has resulted in the Cibabat River being a place to collect domestic wastewater. This of course can reduce water quality as well as reduce the function of the river itself. The Cibabat river is known to be a sub-watershed of the Citarum River with a surface area of 1,855 km2. Activities in the Cibabat watershed contribute to the pollution load that causes the water quality of the Cibabat River to decline, which of course has an impact on the decrease in the quality of the river and increase in the polluting load that the river will receive. The research method uses the calculation of the pollutant load based on Permen LH 115/2003. The data used are secondary data from DLH Cimahi City, which conducted a water quality analysis at three points during three different seasons in 2019. One of the steps to overcome and control the pollution that occurs is to determine the actual pollutant load so that it can easily determine the application of effective technology for controlling river water pollution in the Cibabat River at theCimahi City.

Determination of Quality and Trophic Status of Cibabat Lake, Cimahi City

“…Sulfide is a very toxic gas that smells bad due to putrefactive activity by decomposing bacteria, so sulfide levels in water affect water quality (Alfaroby & Wardhani, 2021). The results obtained for the sulfide parameter at Cibabat Lake did not meet quality standards, the results obtained in 2021 were 0.059 mg/l, and in 2022 they were 0.025 mg/l.…”

“…When taking water samples taken, it was the rainy season, so the water in Cibabat Lake became more turbid due to a large amount of soil or particles carried by the water due to erosion in the waterway area. The soil that settles at the bottom of the lake will experience turbulence when it rains, causing the color of the water to exceed the quality standard (Alfaroby & Wardhani, 2021).…”

“…The results obtained for the sulfide parameter at Cibabat Lake did not meet quality standards, the results obtained in 2021 were 0.059 mg/l, and in 2022 they were 0.025 mg/l. The high content of sulfides is caused by biological oxidation that occurs by microorganisms in water bodies due to the significant range of existing organic pollutants and is one of the things that affects the high BOD value and reduced DO value in a body of water (Alfaroby & Wardhani, 2021).…”

Perbandingan Mutu Air di Bendungan yang Berada di Provinsi Jawa Timur

“…Salah satu upaya untuk meningkatkan ketersediaan air yaitu dibangun bendungan dan memperbaiki kondisi bendungan yang telah ada. Provinsi Jawa Timur saat ini terus melakukan perbaikan bendungan yang telah ada [4]. Langkah yang dilakukan yaitu melengkapi komponen bendungan, memperbaiki kualitas air bendungan, meningkatkan tutupan lahan di daerah p-ISSN : 2528-3561 e-ISSN : tangkapan air, menata kawasan sekitar bendungan serta mengatur sempadan bendungan dikembalikan untuk peruntukan semestinya.…”

Domestic wastewater masterplan for Ciamis Regency

“…According to the 2010-2031 RTRW of Ciamis Regency, Ciamis Regency is divided into 2 areas, namely urban and rural areas. Urban areas have a higher number and density of population than rural areas, so it can be said that the urban areas of Ciamis Regency are more in need of an adequate domestic wastewater management design [3]. Related to this problem, a master plan design of the domestic wastewater management system in the urban area of Ciamis Regency is required [4].…”
