Abstract

Population growth greatly influences changes in land use, and the Cimahi Watershed (DAS) is also experiencing these changes.  The change in land use has resulted in reduced water  quality in the Cimahi River. Water pollution in the Cimahi River is greatly influenced by the discharges from the Cimahi River watershed facilities. This research identifies  a master plan for wastewater management in the Cimahi watershed to improve water quality of the Cimahi River  and establishes a Domestic Wastewater Management System (SPALD) in the Cimahi Watershed region . Wastewater management provisions are regulated by PermenPUPR No. 4 of 2017 through a series of screening. As a result of a series of screenings conducted for the Cimahi watershed, which consists of seven sub-districts, only one sub-district can use the Centralized SPALD, namely Cimahi Village. Two sub-districts of the Cimahi watershed did not meet the  population density selection criteria , and five sub-districts  within the Cimahi watershed did not meet the criteria for a depth review.  Follow-up screening, such as groundwater  permeability, ability to fund , and  slope of the land for all urban villages met the screening criteria.

Abstract

Cibaligo River is the polluted rivers in Cimahi City. The river that flows through three districts and 6 sub-districts in Cimahi City catchment  area of 666.19 hectares of watershed with a total length of 7 km. The land use of the district through which this river passes is domestic, trade, agriculture, livestock and industry whose waste will end into the Cibaligo River. The impact of these activities causes the river to be polluted and a decrease in water quality. The purpose of this study was to determine the status of water quality from upstream to downstream which represents the transition, dry, and rainy seasons. Knowledge of water quality status can be used as basic data for controlling water pollution in rivers. The pollutant index (IP) method used in this study is in accordance with the Decree of the State Minister for the Environment Number 115 of 2003 concerning guidelines for determining water quality status. The results showed that the water quality status of the Cibaligo River from upstream to downstream represented that each season was categorized as heavily polluted with the highest index value being in the rainy season at the downstream point. The main contributor that causes river water to be heavily polluted is domestic wastewater, especially the presence of total coliform and fecal coliform that exceed the established quality standards. Based on the results of the research, efforts to tackle domestic waste are needed to improve the quality of this river water.

Abstract

Groundwater is the  primary source of clean water for  Cimahi City residents. Groundwater quality has decreased due to contamination of domestic wastewater as it is managed  through  local systems that do not meet standards. This study aims to analyse  the feasibility of shallow groundwater as a source of clean water in the town of Cimahi . The data used are  secondary to the Environment Service for  2018. Sampling was conducted  in 12 urban villages such as Citeureup, Pasir Kaliki, Cibeureum, Cibabat, Cipageran, Cimahi, Leuwigajah, Setiamanah, Cibeber, Baros, Karang Mekar, and Melong. There are 1 to 2 samples in  each village  . Based on field measurements, several parameters have not  exceeded the required quality standards, namely turbidity, Manganese, Nitrate, MBAS Detergent, and Total Coliform. Groundwater quality from 20 sampling points only 4 points (20%) which  meet the quality standards and are suitable as a water source, the remaining 16 sampling points (80%) are declared unfit for sampling because  one to three parameters that do not meet the quality standards. Management can occur by improving the local system or by beginning  to plan a centralized wastewater treatment system that uses piping to reduce  groundwater contamination.
