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

Solar power plants are efficient and environmentally friendly sources of renewable energy. Previously, a solar power plant with a capacity of 6 x 100 Wp had been installed at the Al-Ikhlas Orphan Boarding School, Singosari District, Malang Regency, but the power produced was not optimal. Therefore, the addition of solar modules with a capacity of 4 x 100 Wp is carried out. It is necessary to design and analyze solar power plants using pvsyst software to find out how effective the addition of solar panels is so that the total capacity is 10 x 100 Wp. This research includes the design and simulation of solar panels to optimize the system configuration, including the placement of solar panels, tilt angles, and orientation. The analysis is carried out by taking into account location data, equipment specifications, and local environmental conditions. The results of the study show that the design value of solar power plants using PVSYST software is: average annual radiation of 870 kWh/m², temperature value of 24.99°C, PV input power of 1667.2 Watts, output power of 1595.4 Watts, performance ratio of solar power plant 0.809, and efficiency value of 18.8%. After testing in the field, an average efficiency was obtained in sunny weather of 15.47% with an average voltage of 31.62 V, current of 20.03 A, and power of 651.18 Watts. The addition of solar modules significantly improves the energy production and efficiency of solar PV.

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

Briquettes are a form of solid fuel that is produced using waste from the agricultural, industrial and household sectors. For example, briquettes can be produced from biomass waste such as rice straw and corn cobs, which are potential resources that can be utilized to produce bioenergy in the form of briquettes. This study aims to develop and test the characteristics of biomass briquettes in order to evaluate the quality of the biochar briquettes and the calorific value they produce. The method used in this study was experimental, in which the adhesive and the composition of the mixed ingredients were varied as independent variables to affect the quality of the briquettes, while the moisture content, ash content, burning rate,put birds, calorific value is used as the dependent variable. In this study, the results obtained for water content ≤ 5%, volatile matter ≤ 10%, calorific value ≤ 6.553 cal/g, and a burning rate of 0.17 gram/minute which is expected according to the Indonesian National Standard (SNI) 01 6235 2000, namely the water content ≤ 8%, volatille matter ≤ 10%, calorific value ≤ 5,000 cal/g. The results of this study indicate that the biomass briquettes can meet the established quality standards, with appropriate moisture, ash and volatile matter content. In addition, the resulting calorific value also reaches the desired figure, indicating the potential of biomass briquettes as an efficient alternative fuel. The combustion rates found in this study also indicate that the biomass briquettes have characteristics that allow stable and effective combustion. Thus, this research succeeded in developing and testing the characteristics of biomass briquettes as an alternative fuel. The results of this study can contribute to the development of renewable energy sources and efficient use of biomass waste, as well as promote efforts to mitigate the negative impacts of the conventional energy sector on the environment.

Abstract

According to the Air Quality Live Index (AQLI), Indonesia's air quality has continued to deteriorate in the last two decades, so Indonesia is officially ranked 17th as the country with the worst air quality in the world. This is due to the population explosion in Indonesia causing industrial activity to also increase. The high levels of exhaust emissions in vehicles, of course, requires the need for technology to measure vehicle exhaust gases to reduce the impact of air pollution. However, the procurement of exhaust emission test equipment is still expensive, so only certain class workshops have this tool. In addition, the reading results of the vehicle's OBD (On Board Diagnostic) system are only able to display the condition or reading value of the Lambda sensor because other gas sensors readings such as CO2, HC, and CO cannot be displayed on the OBD reading results. The purpose of this study is to describe the design of the tool and the results of measuring CO and HC levels through the Blynk application. Research methods that use several gas sensors, such as MQ-7 and TGS-2602 (CO gas) and MQ-2 and TGS-2611 (HC gas), are then compared with the measurement results of a standard gas analyzer. The results showed that the MQ-7 value is close to the accuracy at 1000 rpm and 5000 rpm, namely 99.68% and 99.49%, while the level of accuracy at 3000 rpm is 99.37%. The TGS-2602 sensor at 1000 rpm only has the best accuracy and accuracy, namely 99.67% and 99.77%. The level of accuracy of the MQ-2 sensor has the best value at 1000 rpm rotation, which is 95.71% and the level of accuracy has the highest value at 7000 rpm rotation, which is 100%. For the level of accuracy of the TGS-2611 sensor, it has an accuracy level of 1000 rpm rotation of 94.65% and the level of accuracy of the sensor obtains very good values ​​at 1000 rpm, 7000 rpm, and 9000 rpm rotation of 100%.

Abstract

Material selection is crucial for ensuring the structural reliability of hydraulic actuator cylinders operating under high-pressure and dynamic loading conditions. Conventional methods, which focus on cost or manufacturing ease, may neglect detailed performance analysis, leading to local stress concentrations exceeding material strength. This research addresses this issue by comparing the performance of AISI 1020, AISI 1035, and AISI A2 tool steel using Finite Element Analysis (FEA) and conducting experimental testing to assess displacement, Von Mises stress distribution, and safety factor under various loads (450 N, 900 N, and 1350 N). The experimental results show that AISI A2 performed best in structural response with the highest safety margin, AISI 1035 exhibited the highest stress, and AISI 1020 exhibited the highest displacement. In FEA, AISI A2 showed a controlled maximum displacement of 0.28 mm with a safety factor of 3.94, compared with AISI 1020, which reached 0.82 mm and a safety factor of 1.23. The findings support the significant influence of material mechanical properties on actuator structural integrity and confirm that AISI A2 provides the highest resistance to deformation and stress concentration. The study demonstrates the effectiveness of FEA in optimizing actuator material selection for high-load applications.

Abstract

When the battery is used, it will generate heat due to chemical processes and external factors like sunlight that make the battery hot on the solar panel-based transport e-scooter. Indirectly, the battery also receives heat from the surrounding environment. Battery temperature also affects the performance, efficiency, and performance of the battery, so to maintain battery temperature, cooling is needed. This study aims to determine the variation of battery cooling temperature on the charging power of LiFePO4 batteries on e-scooters with solar panels. This research method is carried out by making a battery-cooling device as a box with active cooling using a cooling fan to cool the battery inside. After that, it makes a management and monitoring tool for the battery cooling system to regulate and measure the temperature of the ESP32-based battery. After conducting research and data processing, it can be concluded that the advantages of installing a LifePO4 battery cooling system on an e-scooter using solar panels can increase charging power. From all the data obtained, the temperature when charging at 25oC has a power that is 19% greater than the 35oC temperature on the battery
