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

The Community Service (CS) project was implemented in Sumberingin Kidul Village, Ngunut District, Tulungagung Regency, East Java. The target beneficiary was UD. Arta Lumintu, a local SME engaged in beef cattle farming. The farm, established in 2017, was temporarily closed due to the Covid pandemic and resumed operation after a year. Key challenges included high temperatures (24-31°C) and humidity (74-77%), which negatively impacted cattle productivity and excessive electricity consumption for cattle shed operations. The project aimed to address these issues by installing a water spray system with a high-pressure pump and an off-grid solar power system. The system effectively reduces temperature and humidity in the sheds while minimizing electricity costs. The installation consists of a 540 Wp solar panel, a 1500 VA Smart inverter, a 100 Ah VRLA battery, and six pressurized water sprinkler points positioned in various areas of the cattle sheds, powered by a 350 W booster pump. This initiative improves farm efficiency, supports energy independence, and introduces smart farming technology to benefit local farmers.

Abstract

The Community Service (CS) program took place in Sumberingin Kidul Village, Ngunut District, Tulungagung Regency, approximately 100 km southwest of Malang City. The target group for this program includes small and medium enterprises (SMEs) engaged in koi fish spawning. Our partners face several challenges, primarily the reliance on aeration pumps powered by the national electricity grid (PLN) to supply oxygen to the ponds. The program aimed to install a 100 Wp solar panel system to generate clean energy for a low-voltage aeration pump, helping to maintain optimal oxygen levels in the pond and supporting healthy fish growth. The program successfully implemented this solar-powered aerator pump system in the pond area, providing an innovative, sustainable solution that empowers the community by integrating science and technology into fisheries. It is hoped that this program will inspire other fish farmers in Tulungagung and surrounding areas to adopt similar sustainable practices.

Abstract

This study discusses the cooling of water with a system of spraying it into the free air. The energy source to drive the pump uses energy from sunlight. This research is to solve a problem in an area where it is difficult to get water so that the water for the cooling process must be cooled so that it can be used for the next process. The second problem is that the electrical energy is very minimal, so you have to use other energy that can be used for the cooling process. The process of cooling the water spray system into the air was chosen to solve this problem. The tools used in this study were a 600 Wp solar cell, a 300 W water pump and a spray pipe. The research was conducted during the dry season in August. The research results show that the temperature of the water in the pool is not homogeneous the deeper the water in the pool the lower the temperature. The higher the pool water temperature, the longer the cooling time will be. The greater the pump discharge, the faster it will take to cool the pool water. Solar energy is able to supply energy to drive pumps with pool water temperatures up to 45 C. This cooling system can be used at night because it is equipped with batteries. The results of this research can be used and developed to create a larger system. This cooling system does not cause any impact on the environment because the energy source is from sunlight which is environmentally friendly.

Abstract

MIG (Metal Inert Gas) welding is a welding process that uses rolled electrodes which are the same as the base metal and uses a protective gas.  Aluminum is one of the most commonly used metals in the industrial world. Connecting aluminum by welding is a challenge in itself because of its high heat conductivity. This is why a lot of research has been carried out on welding aluminum. This research aims to investigate the effect of travel speed on the tensile strength and macro structure of welds from the robotic welding process. The research was carried out using experimental methods and observing the macro structure of the fracture results. The research results, it was found that changes in welding speed (travel speed) in the aluminum MIG welding process showed a decreasing trend in maximum tensile strength. The highest tensile strength was obtained at the TS variation of 40 mm/minute, while at TS 70 mm/minute the tensile strength was lower. The higher the welding speed, the lower the resulting tensile strength. This is due to reduced heat applied which affects weld penetration and metal joining. A lower welding speed results in better penetration and higher tensile strength, but a speed that is too slow can cause overheating and damage the metal micro structure. The macro structure of the fracture, it was found that higher welding speeds cause fractures that tend to be brittle with defects such as porosity, which can also reduce tensile strength

Abstract

Damage to the grating after being passed by heavy vehicles from trucks carrying hot asphalt during road repairs with asphalting of roads in residential areas is a problem faced. The purpose of community service is to obtain grating made of strong steel that can be passed by trucks loaded with stone or sand or asphalt with a full load and can be entered by rainwater and passed by heavy vehicles without sagging or damage, but can be opened and closed again if desired for cleaning or repairing water gutters. The method applied is a discussion with residents to determine the desired model design, make adequate gratings, install gratings, trials and modifications, and submit to the Head of RT 03 where the gratings are installed. With the installation of good gratings, it is hoped that the safety of residents or guest vehicles can be guaranteed in traffic in the area. Thus, there is synergy between the State Polytechnic of Malang (Polinema) and residents in order to realize safety in community life in RW 06 Tasikmadu, Lowokwaru, Malang City.
