Abstract

Water Supply Company (WSC) of Tulungagung Regency uses treated water from the Jatiwekas WTP for distribution. Water Treatment Installation (WTI) Jatiwekas has three processing units, i.e., WTP with a capacity of 50 L/s (WTP 1), WTP with a capacity of 100 L/s (WTP 2), and WTP with a capacity of 40 L/s (WTP 3). The Jatiwekas WTP consists of flocculation, sedimentation, filtration, and reservoir. The objective of this study is to evaluate the WTP and calculate water demand by considering 90% service coverage. The research was conducted by field observations to obtain information. Based on SNI 6773:2008, most of the Jatiwekas WTP has met the requirements of the package type WTP, except for WTP 3 which has not met because its capacity exceeds the design of the WTP package unit, which only has a discharge rate of 1-50 L/s while the capacity of WTP 3 reaches 100 L /s. The Jatiwekas WTP does not meet the design criteria of the Directorate General of Public Works of Republic Indonesia, which states that the service coverage for small towns with a population of 20,000– 100,000 is 90%, to achieve 90% service coverage, the Jatiwekas WTP needs to increase water production capacity by 123.9 L/s.

Abstract

High population density in urban areas is a challenge in preventing the spread of Covid 19. High population density encourages the occurrence of crowds in public facilities, which has a great potential for the spread of the Covid 19 virus. People's awareness to live clean and healthy is an individual's role in realizing personal health , family and the environment. One of the healthy behaviors is the habit of washing hands with soap, which is an effort to prevent the spread of Covid 19. However, everyone's awareness is different, influenced by their socio-economic background. Education on clean and healthy living needs to be carried out continuously, therefore, ITATS Environmental Engineering Department, conducts community service activities in the form of education on clean and healthy living in Tanah Kali Kedinding Village, Kenjeran, Surabaya.

Abstract

This study aims to determine the concentration of residual chlorine and net total Coliform distributed by Perumdam Maja Tirta Water Supply Company and received by consumers. Water samples were taken from 7 locations on the distribution network a residential area of Perumdam Maja Tirta, the first sample taken at the reservoir of the Water Treatment Plant of Perumdam Maja Tirta and six samples from consumers. The residual chlorine concentration data and Total Coliform were mapped using Surfer 16 Software, producing an iso concentration map in the form of contour lines. The results showed that the concentration of residual water chlorine received by consumers of Perumdam Maja Tirta Mojokerto City ranged from <LoQ 0.1 mg/L to 0.3 mg/L. The further away from the IPA, the concentration of residual water chlorine decreased. Total Coliform parameters ranged from <1.8 – 240/100 ml in water received by consumers of Perumdam Maja Tirta Mojokerto City. There is a need to improve the quality of water services to consumers regarding water treatment and distribution.

Abstract

The 'ILP' company produces bottled milk with chocolate, melon, strawberry, and vanilla flavors in colorless HDPE (High-Density Polyethylene) plastic bottles and aluminum foil covers. The 'ILP' dairy industry wastewater treatment process stages include bar screen, grease trap, equalization tank, flocculation-coagulation, primary clarifier, aeration tank/activated sludge, and secondary clarifier. The research aims to determine the performance of the dairy factory's WWTP (Wastewater Treatment Plant) in terms of TSS (Total Suspended Solids) and COD (Chemical Oxygen Demand) parameters. This field-scale research was carried out for approximately 5 weeks (35 days) at the wastewater treatment plant of the ILP company. Wastewater sampling is carried out at the inlet point, equalization tank, primary sedimentation, aeration tank, and outlet point of WWTP. Wastewater examination conducted in the company's internal laboratory, including temperature, pH, total suspended solids (TSS), and chemical oxygen demand (COD). The dairy factory WWTP (wastewater treatment plant) can generate TSS (total suspended solids) effluent of 22 mg/L and COD (chemical oxygen demand) of 26.8 mg/L to meet the applicable wastewater quality standards. The treatment efficiency of the dairy industry WWTP for TSS is 94.7% and COD is 98.1%.
