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

Sumberingin bathing area is one of the landmarks of Wringinsongo Village, Tumpang, Malang, with strong potential as a natural spring-based edu-tourism destination. Previous community service programs have supported this area through the installation of an Archimedes screw turbine micro-hydropower demonstration unit in 2022 and the development of Archimedes dye cafe in 2023, which combines natural tourism with science-based learning. However, the lack of supporting information media has limited visitors' understanding of the working principles and benefits of the mechanical demonstration tools. This community service program aims to strengthen public education facilities by developing and installing interactive information boards at cafe cepat archimedes. The method included identifying educational needs, designing the board layout and content, fabricating the information board, installing it in the tourism area, and integrating QR codes linked to digital learning materials. The information board was designed with ergonomic considerations to ensure clear readability and accessibility for children, students, and adult visitors. The result of this program is the availability of an interactive public information board that connects physical learning media with digital content, including a YouTube-based explanation of the Archimedes water turbine. This facility is expected to improve visitor learning experiences, increase the educational value of the tourism area, and support BUMDes in developing more innovative and sustainable edu-tourism services.

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

The rapid advancement of defense technology within the Indonesian Army (TNI AD) requires effective, realistic training systems for Counter-Tank Weapons (CTW). Pneumatic CTW trainers have been developed as cost-effective alternatives to live-fire training; however, field tests indicate significant recoil that reduces weapon stability and shooter comfort. Unlike conventional recoil mitigation methods that rely on external dampers, springs, or structural reinforcement, this study proposes an integrated, collision-based counter-recoil mechanism embedded within the valve lever assembly that reduces recoil through internal momentum transfer without adding complex external components. This study aims to design and evaluate the proposed mechanism to reduce recoil force while maintaining firing accuracy and projectile range. Experimental tests were conducted at Politeknik Angkatan Darat under controlled conditions, using three pressure levels (10-30 bar) and three counter pad masses (0.5-1.5 kg), with three repetitions per condition. Recoil force was measured using a calibrated load cell sensor, while projectile range was recorded manually. Data were analyzed using two-way ANOVA to evaluate the effects of pressure and pad mass on recoil behavior. The results show that the proposed internal collision-based counter recoil system significantly reduced recoil force across all pressure levels. At 30 bar, recoil decreased from 81.7 N (without modification) to 65.7 N using a 0.5 kg pad and further decreased to 34.33 N with a 1.5 kg pad. Statistical analysis confirmed that both pressure and pad mass significantly influence recoil force (p 0.001, R² = 98.35%). In addition, the maximum firing range increased from 190.7 m to 221.7 m, indicating improved energy transfer and launcher stability. Although the 1.5 kg counterpad had the lowest recoil force, its additional mass may reduce launcher mobility and operator comfort. The 1.0 kg pad provides a balanced compromise between recoil reduction and ergonomic usability, making it more suitable for routine training applications. These findings demonstrate that the proposed internal collision-based counter recoil mechanism offers an effective, passive, lightweight, and practical solution for mitigating recoil in pneumatic CTW training launchers while preserving operational realism and ease of maintenance.

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

Efficient battery thermal management systems (BTMS) are essential for ensuring the safety and performance of lithium-ion batteries in electric vehicles. This study numerically investigates the influence of serpentine channel curvature on the thermal and hydraulic characteristics of a liquid-cooled prismatic battery module. Four channel designs were evaluated: a base case and three serpentine configurations with curvature values of 0.075 mm⁻¹, 0.1 mm⁻¹, and 0.15 mm⁻¹. Simulations were conducted under steady-state and transient conditions with discharge rates of 0.5C–2C and mass flow rates of 2.41 × 10⁻³ – 3.61 × 10⁻² kg/s. The results show that higher curvature and mass flow rates reduce maximum battery temperature and improve temperature uniformity, but at the expense of increased pressure drop and pumping power. At 3.61 × 10⁻² kg/s, the base-case channel exhibited a 28% increase in pressure drop compared to 2.41 × 10⁻² kg/s, while the 0.15 mm⁻¹ channel recorded up to a 60% rise under the same condition. Transient analysis revealed that curved channels enhanced heat dissipation, achieving up to 8.56% higher cooling performance than the base case. These findings highlight the trade-off between thermal improvement and hydraulic penalty, providing valuable guidance for optimizing liquid-cooled BTMS in electric vehicle applications.
