Abstract

The problem faced is that the white chromium coating has a low selling value or aesthetic value than the black chromium layer which is more in demand, especially by the younger generation who prioritizes aesthetics. The purpose of the corrosion test was to determine the corrosion resistance ability of the black chromium coating resulting from the electroplating process on the relationship between the solution temperature and the immersion time of copper in a corrosive solution. Corrosion test methods include literature studies, field observations, weighing specimens, immersing specimens in corrosive solutions, weighing specimens, calculating corrosion rates, and data analyzing. Corrosion test results show that the higher the temperature of the solution and the longer the immersion time, the smaller the corrosion rate for the lowest conditions at 30oC and a duration of 5 minutes with a corrosion rate of 0.2004 mm/year and the highest conditions at a temperature of 50oC and a duration of 9 minutes at a rate of corrosion of 0.0108 mm/year.

Abstract

Community Service (PPM) is held in Sumberejo Village, Sanankulon District, Blitar Regency. Chicken farmers face several challenges related to heating their chicken coops, including restrictions on using subsidized fuel or LPG, which force them to seek other heating alternatives. Leaks in heating systems that use LPG, which pose a fire hazard. Poor air quality and low oxygen levels in coops that use conventional heating methods (firewood and LPG). These challenges can contribute to the decline in the quality of Day-Old Chicks (DOC). This activity aims to install an electric warmer system that produces a safe and comfortable temperature for Day-Old Chicks (DOC) and is easy to use for breeders. In addition, build an independent energy source to run the heat treatment system equipment in the DOC-Brooding area with a solar panel installation. The installed 600 Wp PLTS system consists of 4 solar panels with a capacity of 150 Wp each, an 850 VA hybrid inverter and 100 Ah VRLA battery. Electrical energy from PLTS can power a 200 W electric warmer. The solar panel installations can produce an average of 3.6 kWh of electrical energy/day. So that the electricity savings from PLN can reach IDR. 162000 per month.

Abstract

Access to clean water remains a critical global challenge, particularly in disaster prone and rural areas where infrastructure is often damaged and electricity access is limited. This study aims to develop a portable solar powered water purification system integrated with Internet of Things technology to support emergency water supply. The system utilizes a five stage filtration process powered by a 12 V solar panel and monitored using an Arduino Uno microcontroller connected to pH, turbidity, and temperature sensors. Real time data transmission is enabled through an ESP8266 module and monitored via a mobile application platform. Performance evaluation was conducted by measuring temperature, turbidity, and pH across five filtration stages. The results indicate a significant reduction in turbidity from 724 NTU to 26 NTU and stable temperature variation within 0.4 °C, demonstrating effective particle removal and thermal consistency. However, instability was observed in the pH parameter, including an unrealistic initial reading and a final acidic value of 3.67, indicating the need for sensor recalibration and chemical stabilization. The findings suggest that integrating renewable energy, multi stage filtration, and real time monitoring provides a promising approach for portable water treatment systems, although further optimization is required to ensure drinking water safety standards in disaster relief applications.

Abstract

White oyster mushrooms (Pleurotus ostreatus) represent a vital agricultural commodity and a major source of income for residents of Dusun Wiloso, Desa Gondowangi, Kecamatan Wagir, Kabupaten Malang. Despite their economic potential, the productivity of local mushroom farmers remains constrained by the conventional manual process of preparing baglog planting media, which involves mixing wood sawdust and rice bran. This traditional method is not only labor-intensive and time-consuming but also prone to inconsistencies that may damage the planting media and reduce overall yields. In response to these challenges, the Community Service Program (PPM) introduced an innovative training and technology transfer initiative focused on the design, fabrication, and utilization of a mushroom planting media mixing machine. This intervention effectively mechanizes the mixing process, thereby improving production efficiency, ensuring greater uniformity and quality of the planting media, and enhancing cultivation outcomes. Beyond its technical advantages, the program promotes local capacity building by expanding community knowledge in mechanical engineering and fabrication, fostering innovation, and stimulating entrepreneurial opportunities among local fabrication workshops. These workshops play a strategic role in sustaining the availability of appropriate agricultural technologies, supporting the continuous improvement of mushroom cultivation systems, and strengthening the region’s technological independence. Consequently, this PPM initiative not only addresses critical production bottlenecks but also contributes to broader goals of rural economic development, technological empowerment, and sustainable community self-reliance within Dusun Wiloso.
