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 investigates the impact of solar charge controller (SCC) type on battery charging in solar-powered electric scooters (e-scooters). The research compared maximum power point tracking (MPPT) and pulse width modulation (PWM) controllers by monitoring average output power, current, and voltage every 10 minutes. Results showed that under stationary conditions, MPPT controllers delivered higher efficiency, generating 5.87 W of power compared to PWM's 5.05 W. This advantage persisted even during scooter operation, with MPPT controllers producing 4.91 W versus PWM's 4.31 W. Overall, the findings demonstrate that MPPT SCCs offer a more efficient solution for charging e-scooter batteries.

Abstract

Community service activities have a central role in supporting sustainable economic growth, especially in the Micro, Small and Medium Enterprises (UMKM) sector. UMKM processing wood-based crafts, as an integral part of local cultural diversity, face significant energy challenges in sustainable development. In order to overcome this obstacle, this community service activity focuses on implementing a Hybrid Solar Power Plant (PLTS) that is integrated with a lathe for UMKM processing wood-based crafts. The purpose of this community service activity is to provide sustainable solutions for UMKM in terms of reliable energy, while supporting the development of environmentally friendly technologies. The methodology applied includes an initial survey of energy needs, design and installation of the Hybrid PLTS system, lathe operator training, and continuous performance monitoring. This activity involves collaboration with UMKM owners and the local village government to ensure the implementation of solutions that are relevant to real needs and conditions. The results of this activity show that the implementation of Hybrid PLTS integrated with lathes has a significant positive impact on production efficiency and product quality for UMKM. These activities make a real contribution to sustainable economic development at the local level. The results can be used as a model for similar developments in other UMKM sectors.

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.

Abstract

The Sumberingin Baths, a prominent landmark of Wringinsongo Village, represent one of the region’s most promising tourism destinations, supported by facilities such as photo spots, food stalls, places of worship, and gazebos for visitor comfort. Since 2022, the site has been enriched through the installation of an Archimedes Screw Turbine Micro Hydroelectric Power Plant (MHPP) as an educational display under the DIPA Swadana Partnership Community Service program. In 2023, the same initiative facilitated the construction of a café whose architectural design uniquely integrates natural and scientific elements, offering visitors a rare and engaging thematic experience. Despite these developments, the area remains limited in mechanical attractions that combine education with entertainment. Addressing this gap, the 2024 DIPA Swadana Regular Competition Community Service program introduced the installation of a rhythmic water wheel that harmonizes nature and technology. Designed as both a visual centerpiece and an interactive learning medium, the water wheel transforms water flow into rhythmic motion by driving musical instruments, thereby creating an innovative educational adventure that blends natural beauty with technological insight.

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

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.
