Abstract

This PKM was carried out by the UMB team in partnership with the Nurul Yaqin Recitation Group, Parigi Baru Village, Pondok Aren District, South Tangerang, and was funded by DRTPM DIKTI through the PPM Grant Program for the 2024 fiscal year scheme. The Nurul Yaqin Recitation Group has 19 members; apart from being homemakers, they also have informal workers and small home industry businesses. This recitation group carries out its routine activities, namely conducting religious studies under the care of the DKM Masjid Baitul Mukminin. It is active in various community activities and can mobilize other community members through activities. Therefore, they have the potential to be pioneers among grassroots communities to change people's lifestyles for the better through the green movement in their area. The problems experienced by partners are: 1) the accumulation of organic and inorganic waste in the area around their residence has not been appropriately managed, 2) There is no utilization of business opportunities for compost and recycled crafts, 3) There is no accounting application system to record transactions and financial reporting from the production of liquid fertilizer and solid fertilizer and the recycling of inorganic waste. The solutions offered are: 1) Provide training and counseling related to processing organic and inorganic waste into valuable products 2) Provide training related to digital marketing strategies 3) Provide training related to recording transactions and financial reporting through accounting software applications.

Abstract

Engine lubricant oil is crucial for minimizing friction between moving components within an engine, directly influencing the engine's reliability and lifespan. Determining the appropriate oil replacement intervals is essential, as extending these intervals necessitates more rigorous monitoring of both oil quality and engine condition. This study investigated the performance of SAKAI 15W-40 DH1 engine oil in the SAKAI Vibrating Roller SV526 over varying operational periods: 125 hours, 250 hours, 375 hours, and 500 hours. The research involved analyzing oil samples for viscosity, metal additives, total base number (TBN), and contaminants using Fourier Transform Infrared Spectroscopy (FTIR). Additionally, key engine performance indicators, including fuel consumption, valve clearance, and compression pressure, were measured. The findings revealed a gradual decrease in oil viscosity from 13.48 cSt to 11.56 cSt, approaching the minimum acceptable threshold of 11.45 cSt. Concurrently, the Fe content in the oil increased to 11 ppm, indicating wear, while the valve clearance in cylinder number three expanded to 0.48 mm, and compression pressure dropped from 31 kg/cm² to 28 kg/cm². Despite these changes, the oil remained within the standard operational limits, and the engine continued to perform adequately. However, based on the observed trends, extending the oil replacement interval to 500 hours cannot be conclusively recommended, as the oil's condition and engine performance may begin to decline beyond this point.
