Abstract

The source of clean water for the people of Sukaluyu Village, Telukjambe Timur District, Karawang Regency comes from surface water, namely from the Drinking Water Company (PAM), and some comes from ground water. Excessive groundwater withdrawal will cause the volume of groundwater to shrink. On the other hand, during the rainy season, due to excess water discharge, the problem that often arises is flooding. These floods can occur in areas close to rivers. One alternative to fulfilling the need for clean water in Sukaluyu Village is by making Rainwater Harvesting with appropriate technology. Rainwater Harvesting is a way to collect and store rainwater from rooftops when it rains. The method used is socialization of PAH installation online. The purpose of this Community Service activity is to invite the people of Sukaluyu Village to actively participate in creating alternative appropriate technologies. The method of carrying out this activity is to conduct counseling and training on installing the PAH tool system online. The results of the implementation of this PKM activity can be concluded that this PKM activity can add insight to KSM Friends of the Environment members and the community in Sukaluyu Village, Teluk Jambe Timur District, Karawang Regency regarding the benefits of rainwater and the installation of rainwater harvesting system tools which can be used as an alternative source of clean water

Abstract

Liquid waste generated by the chicken slaughterhouse industry results in an increased concentration of organic matter decomposes in the environment. High organic matter content can be achieved by the coagulation-flocculation method. This study aims to determine the removal efficiency of turbidity, BOD, COD, and TSS in the reactor. A dose of 250 mL with a coagulation speed of 100 rpm 1 minute and a flocculation speed of 25 rpm 10 minutes with a variation of settling time of 1.5 hours, 2 hours, and 2.5 hours of moringa seeds were investigated to find reduction levels of turbidity, BOD, COD, and TSS. This study showed that moringa seed coagulants were able to reduce the BOD concentration by 87.74% with an initial level of 662 mg/L to 101.01 mg/L in 2.5 hours, a COD concentration of 61.43% with an initial level of 2240 mg/L to 864 mg/L at 2.5 hours, the TSS concentration was 77.78% with an initial level of 360 mg/L to 80 mg/L at 2.5 hours while the turbidity value was 87.73% with an initial level of 441 NTU to 54.1 NTU. Moringa seeds could be effectively used to reduce the parameters of turbidity, TSS, BOD, and COD.

Abstract

The increase in the amount of groundwater withdrawal will inevitably pose a threat of seawater intrusion. The purpose of this research was to identify the distribution of shallow groundwater salinity in North Jakarta, West Jakarta and Central Jakarta and to develop a regional model of shallow groundwater salinity distribution. The data used in this study was that of the groundwater quality monitoring, obtained from the Regional Environment Status Book (SLHD), published by The Environment office of Greater Jakarta released in 2022, involving a total of 121 sample points in North Jakarta, West Jakarta, and Central Jakarta. The primary data was taken at 6 (six) sampling locations for model validation purposes. The study began with data grouping, using the Hierarchical Cluster Analysis (HCA) method. The results of identifying the highest distribution of salinity are in cluster 3 (three). A model was subsequently developed, after removing the outliers, with multiple linear analysis methods using the variable the distance from the coastline (X1), well depth (X2) and hardness (X3), to determine the influence of EC, TDS and salinity distribution in shallow groundwater. The results obtained are as follows; EC Models: YEC3 = -1.879+ (1.19.X1) + (5.08.X3). TDS models: YTDS3 = -2.211.30 + (0.81.X1) + (101.41.X2) + (4.07.X3). Salinity models: Ysalinity3 = -0.07+ (6.75×10-5.X1) + (2.4×10-4.X3). Model verification results for R2EC3 = 0.70; R2TDS3 = 0.92; R2salinity3 = 0.88. Validation results produce 21.14% for EC, 8.21% for TDS, and 22.87% for Salinity. This needs further research by increasing the number of primary samples.

Abstract

Wastewater produced from chicken slaughterhouse (RPA) industrial activities is liquid waste containing organic compounds in high concentrations that have the potential to damage the environment if not treated first before being discharged into water bodies. This study aims to determine the effectiveness of moringa seed biocoagulant performance in removing BOD, COD, and TSS parameters. The dosage variations of moringa seed biocoagulant used in this study were 20 mg/L, 30 mg/L, 40 mg/L, 50 mg/L, 60 mg/L, and 70 mg/L with a coagulation speed of 120 rpm for 2 minutes, a flocculation speed of 20 rpm for 20 minutes, and a settling time of 2 hours. The results of the study showed that the optimum dose of moringa seed coagulant which had the lowest turbidity level was at a dose of 50 mg/L, where the optimum dose of coagulant could be effectively used in the removal of BOD, COD, and TSS pollutant parameters at a dose of 50 mg/L with a BOD removal of 49.8% from the initial characteristics of 1,683.5 mg/L to 845.12 mg/L, COD removal of 27.2% from the initial characteristics of 4,060.8 mg/L to 2,955.36 mg/L, and TSS removal of 30.4% from the initial characteristics of 427 mg/L to 297 mg/L. The RPA wastewater effluent that had been treated using moringa seed biocoagulant could remove BOD, COD, and TSS pollutant parameters in chicken slaughterhouse wastewater, but still did not meet the Quality Standards of the Minister of Environment Regulation No. 5 of 2014.
