Abstract

The distribution network of the Banjarsari water treatment plant uses a gravity system. The system serves the drinking water in Banjarsari Villages. This study aims to optimize the pressure of the water distribution network in the Banjarsari Villages. This system supplies water from the Banjarsari water treatment plant. The water distribution network uses the gravity method to deliver water to customers. The drinking water distribution network was obtained from PDAM Bojonegoro. Meanwhile, the elevation and node of pipe were obtained by using Google Earth. Before optimization, the water distribution network has negative pressure at 07.00 AM and 05.00 PM. The negative pressure zone is at the end of the distribution network. The negative pressure values obtained using EPANET is range from -0,67 meters to -6,34 meters. The water distribution network is optimized by replacing diameter pipe in some areas, the water pressure increases significantly and makes the water distribution has positive pressure values. The pressure values are range from 2,70 meters to 13,65 meters. Replacing diameters of pipe is a solution to remove negative pressure, so that water from the reservoir can deliver to the end of a pipe. The distribution network pipe diameter is chosen which is close to the calculated pipe diameter.

Abstract

B is a livestock industry company located in Ngadirenggo Village, Wlingi District, Blitar Regency. The main focus of environmental pollution by PT. B leads to water pollution, especially rivers. Domestic Wastewater Treatment Plant (WWTP) PT. B comes from 4 sources, namely Mess, MCC (Milk Collect Center), Canteen, and Laundry Room which are then discharged into the Genjong River water body. This study aims to determine the characteristics of wastewater in the domestic Wastewater Treatment Plant (WWTP) of PT. B, analyze the effectiveness of the performance of domestic WWTP in treating waste, and evaluate domestic WWTP buildings when compared to the design criteria of water treatment plants in the literature study. The research was carried out for approximately 3 months starting from January 20, 2025 to April 14, 2025. The location of the research of PT. B. Primary and secondary data collection was carried out in this study. The quality of the wastewater produced exceeds the quality standards set by the Regulation of the Minister of Environment and Forestry of the Republic of Indonesia Number 68 of 2016, especially in the parameters of TSS, COD, BOD, and total coliform. Evaluation of the WWTP building showed that some units did not meet the expected design criteria, such as the initial and final reservoirs that had too large a volume and inappropriate residence times. Suggestions for improvement include installation of a mechanical mixer system

Abstract

Occupational Safety and Health is a crucial aspect in operational activities in the industrial sector, including the livestock industry such as PT. Q. In large-scale livestock activities, potential hazards to workers, livestock, and the surrounding environment can arise from various routine activities, such as waste processing and maintenance of existing facilities. Therefore, the implementation of an OHS system is needed to minimize work risks and ensure the continuity of safe and efficient operations. This study aims to determine the risk of work accidents, classify potential hazards, and evaluate and provide additional risk controls in the sandtrap and heifer areas of PT. Q. The FMEA method has the advantage of being able to explain various risks in detail and comprehensively, helping to improve future work, and is able to identify accident risks based not only on one criterion, but also on three criteria: severity, frequency of occurrence, and detectability. The data collection used was obtained from interviews with 7 respondents, observations, and documentation. The data collection techniques used were interviews and direct practice. Therefore, some suggestions that can be given are using remote operator tools in the machine operator section, adding protection to the screen section and moving roller separator machines, carrying out routine maintenance on the roads used, installing K3 signs in every road traffic, providing first aid kits in every department, and providing K3 socialization to all company staff involved.
