Abstract

Water is an important need for all life on this earth. The need for clean water always increases in line with population growth, while the supply of clean water continues to decrease. This research was conducted in Bina Loka hamlet block 4, Kaduela Village, Kuningan Regency. The problem that occurs in Bina Loka block 4 hamlet is that it does not receive a clean water supply from the water source available in Kaduela village, namely Tegala Biru Cicerem. So far, residents have received water supplies for their daily needs from neighboring villages, but the quality of the water is not suitable for consumption because it is yellowish in color and residents often complain that using the water causes problems, one of which is itching and diarrhea when consumed. For this reason, clean water distribution planning was carried out in Bina Loka hamlet block 4 with a total of 6 residents' houses, with an average of 8 people in each house. The design was carried out using the dead end system method with the help of the epanet 2.2 application with the target of each house getting water pressure of 5 – 7 mH2O and a minimum flow rate of 8 lpm per house.

Abstract

This study focuses on the design of a clean water distribution piping system for Bina loka Hamlet, Block 6, using EPANET 2.2 software. The research aims to address the challenges faced by the local community, including geographical constraints and varying water quality, by designing an efficient distribution system. The methodology involves collecting both primary and secondary data, including topographical surveys and water demand assessments. Using EPANET 2.2, the study simulates the hydraulic and water quality behaviors within the pipe network, optimizing the system for pressure and flow rates. The results indicate that the proposed design meets the necessary criteria for an effective water distribution system, ensuring adequate water supply and quality for the residents.

Abstract

Forage is the main component in ruminant farming, but manually chopping grass is considered inefficientin terms of time and effort. This study aims to design and build a grass chopper machine with blade anglevariations of 15°, 30°, and 60°, as well as to find out the effect of each angle on production capacity, thequality of the chopped grass, and cutting efficiency. The machine is designed using a Honda GX160gasoline engine with 5.5 hp, an 8:1 ratio pulley transmission system, a frame made of angle iron, and HSSsteel blades, with machine dimensions of 80 cm long, 45 cm wide, and 101.11 cm high. Testing was carriedout by inserting 3 kg of grass material for each blade angle variation. The test results showed that a 60°blade angle couldn’t be used because it collided with the machine body. A 15° blade angle gave aproduction capacity of 72 kg/hour with a cutting efficiency of 63% and uneven chopping quality.Meanwhile, a 30° blade angle provided the best performance, with the highest production capacity of 90kg/hour, cutting efficiency reaching 66%, and even chopped quality. Based on these results, it wasconcluded that a 30° blade tilt is the most optimal angle to use on a grass chopper machine for producinggood-quality chops more efficiently.
