Abstract

This study investigates the development and implementation of a dual-axis solar tracking system for off-grid 100Wp photovoltaic (PV) systems to enhance energy harvesting efficiency and ensure sustainable power generation. The research addresses the limitations of fixed-tilt PV systems, which often underperform due to suboptimal solar alignment, especially in regions with dynamic weather conditions. The results demonstrated a significant increase in energy output, achieving up to 13,75% higher efficiency compared to static systems under similar operational conditions. This improvement is attributed to the system's ability to maintain optimal solar panel orientation throughout the day, facilitated by an advanced tracking algorithm and real-time sensor integration. The distinctive features of the developed system include its cost-effective design, adaptability to various geographical locations, and robust performance under fluctuating environmental conditions. The findings suggest that the dual-axis tracking system is wellsuited for deployment in remote or off-grid areas where reliable and efficient power generation is critical. Practical applications of this system are particularly relevant for rural electrification, agricultural irrigation systems, and other decentralized energy solutions in regions with abundant solar resources.

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

The increasing global energy demand and dependence on fossil fuels have driven the development of renewable alternatives from agricultural waste. Corn cobs and coconut shells are abundant lignocellulosic biomass wastes in Indonesia that remain underutilized as biobriquette raw materials, and previous studies generally optimized only one or two process parameters separately. This study aims to determine the optimal combination of process parameters for producing high-quality biobriquettes from corn cobs and coconut shells that meet the Indonesian National Standard (SNI 01-6235-2000). An experimental approach applied the Taguchi Orthogonal Array L9(3⁴) integrated with Grey Relational Analysis (GRA) to simultaneously optimize four factors, namely shell to cob ratio, tapioca adhesive concentration, carbonization temperature, and particle size, against five quality characteristics: calorific value, moisture content, ash content, volatile matter, and fixed carbon. The optimal combination was a shell to cob ratio of 75:25, adhesive concentration of 5%, carbonization temperature of 500°C, and particle size of 60 mesh, producing the highest Grey Relational Grade of 0.8891, with raw material ratio as the most dominant factor. The confirmation experiment produced biobriquettes with a calorific value of 6,759 cal/g and other characteristics fully satisfying SNI 01-6235-2000, with a prediction error of 7.99%. These findings confirm that the Taguchi-GRA approach is effective for simultaneous multi-parameter, multi-response optimization of agricultural waste-based biobriquettes.

Abstract

Sistem Continuously Variable Transmission (CVT) merupakan komponen vital pada sepeda motor matic, dan kinerjanya sangat dipengaruhi oleh geometri drive pulley serta kondisi permukaan mangkok kartel. Penelitian ini bertujuan untuk menganalisis pengaruh sudut drive pulley dan kedalaman kartel mangkok kopling terhadap daya, torsi, dan tingkat kebisingan pada sepeda motor matic 160 cc. Penelitian ini menggunakan metode kuantitatif eksperimental dengan variasi sudut drive pulley 13,4°, 14,4°, dan 14,9°, yang dikombinasikan dengan variasi kedalaman kartel mangkok kopling 1 mm, 2 mm, dan 3 mm. Daya dan torsi diukur menggunakan dynotest pada putaran mesin 6000–9000 rpm, sedangkan tingkat kebisingan diukur menggunakan sound level meter pada jarak 5 cm dari sistem CVT. Setiap kombinasi perlakuan diuji sebanyak lima kali, dan data dianalisis menggunakan Two-Way Anova dengan taraf signifikansi 0,05. Hasil penelitian menunjukkan bahwa sudut drive pulley, kedalaman mangkok kartel, serta interaksi keduanya berpengaruh signifikan terhadap daya, torsi, dan tingkat kebisingan (p < 0,05). Kombinasi drive pulley 14,4° dengan mangkok kartel 1 mm menghasilkan daya tertinggi sebesar 12,55 HP dan torsi tertinggi sebesar 12,65 Nm pada 7000 rpm, sedangkan tingkat kebisingan terendah sebesar 106,24 dB diperoleh dari kombinasi drive pulley 13,4° dengan mangkok kartel 1 mm. Temuan ini menunjukkan bahwa konfigurasi 14,4°–1 mm memberikan keseimbangan terbaik antara peningkatan performa dan kenyamanan berkendara.

Abstract

Small Off-Grid photovoltaic systems require a charge controller to transfer energy safely from the photovoltaic module to the battery. This study characterizes the input-output performance of a 30 A pulse-width-modulation solar charge controller connected to a 20 Wp photovoltaic module and a 12 V, 12 Ah battery. Field measurements were conducted in Tunggul Wulung, Lowokwaru, on 5 September 2026 at one-hour intervals from 08:00 to 16:00. Solar irradiance, module surface temperature, photovoltaic voltage-current, and battery-side voltage-current were recorded. Input power, battery charging power, instantaneous measured efficiency, and interval energy efficiency were calculated. Irradiance ranged from 5.0 to 143.8 W/m² and module temperature from 25.4 to 62.5 °C. The maximum panel power was 2.680 W at 08:00, whereas the maximum battery-input power was 2.361 W at 10:00. Trapezoidal integration yielded 12.524 Wh of panel energy and 10.647 Wh of battery-input energy, corresponding to an aggregate energy efficiency of 85.01%. Instantaneous ratios above 100% at 14:00-16:00 occurred at very low power and are interpreted as apparent efficiencies affected by measurement resolution and non-simultaneous readings, not as physical conversion gains. The results provide a preliminary field baseline and emphasize synchronized measurements and uncertainty reporting for subsequent testing.
