 Considering the current importance watercourses quality conservation, it is important to establish relationships between parameters that enable evaluation of the origins of changes in water quality, allowing actions to mitigate them. However, it is important to improve the association of different variables and to take sufficient samples. This study associates usual techniques and parameters to analyse the water quality of an urban river from Paraná State, Brazil. For this, we used biological indicators (aquatic macroinvertebrates), physical-chemical (temperature, turbidity, true colour, pH, DO and BOD5,20) indicators and microbiological (faecal and total coliforms) indicators. These indicators were related to land use and occupation classes obtained from high resolution QuickBird 2 images. For this association, the surroundings (450 meters buffer) of three distinct points of the river were considered: I. Near the spring; II. In the downtown city; and III. In a residential neighbourhood. Different values of physical, chemical and microbiological variables were detected along the river, showing evident relationships between them and with the use and occupation of the urban and peri-urban space in the characterization of surface waters. The association design was able to detect the landscape effect on water quality in a coherent way and that these connections were mainly related to suppression of the riparian forest present in the surroundings, further demonstrating the importance of this vegetation for the maintenance of watercourse quality.

And Control

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.

ABSTRAKAir limbah Rumah Potong Hewan (RPH) yang tidak dikelola dengan baik dapat menimbulkan masalah lingkungan dan gangguan pada masyarakat yang bertempat tinggal di sekitar RPH. Sejak RPH X beroperasi pada tahun 2009, pengelolaan air limbah RPH X masih belum berjalan optimal. Hal ini dikarenakan air limbah RPH X masih dilihat sebagai materi yang tidak berguna dan dibuang. Saat ini, praktik pengelolaan air limbah RPH X dilakukan dengan menggabungkan semua air limbah kemudian air limbah tersebut diolah dengan Instalasi Pengolahan Air Limbah (IPAL). Riset ini mencoba menganalisis praktik pemotongan sapi, fasilitas RPH, pengelolaan air limbah RPH, kualitas air limbah RPH, dan dampak limbah RPH pada masyarakat. Riset ini menggunakan pendekatan metode kuantitatif dan kualitatif, melalui observasi, wawancara, kuesioner, dan uji laboratorium. Hasil riset menunjukkan bahwa praktik pemotongan sapi di RPH X termasuk kategori baik, fasilitas RPH X termasuk kategori kurang sesuai dengan persyaratan, pengelolaan air limbah RPH X belum berjalan optimal, kualitas air outlet IPAL telah memenuhi baku mutu, dan dampak limbah RPH X pada masyarakat berupa gangguan bau yang dirasakan oleh 100% responden dan gangguan kesehatan berupa mual yang dirasakan oleh 41% responden. Alternatif peningkatan dalam pengelolaan air limbah RPH yang dapat dilakukan adalah minimisasi air limbah melalui segregasi dan pemanfaatan air limbah RPH.Kata kunci:    Rumah Potong Hewan, praktik pemotongan sapi, fasilitas RPH, pengelolaan air limbah RPH, kualitas air limbah RPH, dampak limbah RPH, minimisasiABSTRACTWastewater of slaughterhouse is not managed optimally can cause environmental problems and disruption to communities living around the slaughterhouse. Since slaughterhouse X operates in 2009, wastewater management of the slaughterhouse X is not managed optimally. This is because the wastewater of the slaughterhouse X is seen as useless and discarded material. Currently, the wastewater management of the slaughterhouse X is carried out by mixing all of the wastewater and then the wastewater is treated by Wastewater Treatment Plant (WWTP). This study analyzes practice of cattle slaughtering, slaughterhouse facilities, wastewater management, wastewater quality, impact of slaughterhouse waste. This study exercises quantitative and qualitative methods, through observations, interviews, questionnaires, and laboratory test. The results showed that the practice of cattle slaughtering was categorized into good, the slaughterhouse X facilities were categorized into less suitable, the wastewater management of slaughterhouse X is still not managed optimally, the wastewater quality of WWTP outlet is comply with water quality standards, and the impact of slaughterhouse waste to the communities living around the slaughterhouse is odor disruption felt by 100% of respondents and health issue are nauseous felt by 41% of respondents. An alternative to improving wastewater management of slaughterhouse is minimization through segregation and utilization of slaughterhouse wastewater.

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.
