Abstract

The Cakung River is a river located east of Jakarta and empties directly into the Cilincing estuary, on the coast of DKI Jakarta. The Cakung River crosses a densely populated area and becomes a waste disposal site for various types of industries, resulting in a decline in river water quality. The decline in the quality of the Cakung River will affect Jakarta’s coastal area which has a strategic ecological function. This study aims to analyze the water quality and water quality status of the Cakung River using the pollution index method. The results were also compared with measurements in 2021 and 2019. Laboratory analysis showed that the main pollutant parameters such as TSS, BOD, COD, and Faecal coliform exceeded the quality standards at all sampling points. The range of TSS values was 42-3450 mg/L, BOD 11.1-23.64 mg/L, COD 30-100 mg/L, Faecal coliform 5x106-9x106 MPN/100 mL. The pollution index calculation results show that the Cakung River is severely polluted with index value ranging from 13.92-14.86 and the level of severe pollution has also been going on since 2019. Therefore, serious efforts to control pollution in the Cakung River are needed.

Abstract

Processing of  wastewater in chicken slaughterhouses is a must in the framework of environmental preservation. Currently, there are many water outputs resulting from wastewater treatment in chicken slaughterhouses that still do not meet the quality standards for wastewater treatment set by the government. Problems in the wastewater treatment plant are mainly caused by the design and capacity of the incoming waste to the wastewater treatment plant which exceeds the initial design. The use of Filtration and Ozone technology is used to reduce the values of BOD, COD, and TSS in wastewater. This study aims to look at the values of BOD, COD, and TSS and their effectiveness with the use of Filtration systems and a combination of Filtration systems and Ozone systems. The research method uses physical and chemical methods, namely the filtration system which is expected to reduce the TSS value and also react wastewater after filtration with ozone mixed water to reduce BOD and COD values. The results of this study showed that the BOD value decreased by 97.14%, the COD value decreased by 64.27%, while the TSS value decreased by 97.14%.

Abstract

The Klagison River Watershed has an area of 1.997,6 ha and is experiencing rapid development in the physical field. The problem that often occurs in the Klagison watershed is that when there is heavy rain, several places close to the river will experience flooding, which is caused by several factors, one of which is the runoff coefficient. The aim of this study was to analyze the runoff coefficient of Klagison watershed. The method used to analyze the runoff coefficient is Cook's method, through the analysis of Geographic Information Systems (GIS) on several maps, such as maps of slope, vegetation cover, flow density, and soil infiltration. The results showed that the distribution of runoff coefficients that occurred in the Klagison watershed was dominated by the high class of 69,919% with an area of 13,967 km², the normal class of 21,500% with an area of 13,967 km², and the extreme class of 8,580% with an area of 1,714 km². Overall, the Klagison watershed is included in the high category with a runoff coefficient value of 62,603 %. This means that from 100% of the rain that falls, 62,603% will flow and 37,397% will infiltrate into the ground.

Abstract

The Sidoarjo Volcanic Mudflow has been one of Indonesia's ongoing national catastrophes since 2006. Numerous studies have been conducted to examine the potential applications of this abundant material due to its massive quantity. In this work, Sidoarjo Volcanic Mud was utilized as a dye-removing adsorbent in batik wastewater. To increase the effectiveness of Sidoarjo Volcanic Mud as an adsorbent, physical and chemical activation techniques were employed, and the results were compared to a control without activation. The sample was heated at 550 °C for three hours to be physically activated. The sample was chemically activated by applying 5N H2SO4 solution for 2.5 hours. In a batch system with an orbital shaker, adsorption tests were conducted for the color removal of pure and pre-treated batik wastewater. Using UV-Vis spectrophotometry, the decolorization of batik wastewater was monitored during the reaction. Due to the high concentration of apparent color in the sample, the effect of the adsorbent activation method was insignificant in pure batik wastewater. In contrast, the effect of the adsorbent activation method was evident in pre-treated batik wastewater, where up to 50% decolorization of the true color was achieved with chemically activated, 18.75% with no activation, and 23.30% with physical activation.
