Abstract

This experiment discusses the effect of the variability of solar radiation due to partial shading and surface temperature of the PV Panel on the output power of 100 Wp solar panels. This study begins by determining the load of the system, i.e. DC pump in the nutrient circulation system of the DFT hydroponic system. From there, we can observe the change in solar panel power output and PV surface temperature change due to partial shade. This survey method actually measures the temperature and intensity of solar radiation  and measures the power output of a solar panel, and the tools used are thermal sensors used to measure the surface temperature of solar panels. Solar power meter. to measure the solar irradiance and use the multimeter to measure the voltage and current, 10A capacity SCC battery, 100Wp capacity solar panel and 65Ah battery. The test will be conducted for 5 days, starting from 09:00 to 15:00 every day. This result shows that temperature increase affects the output power decrease when the solar panel is in normal condition (not half shaded condition). On the other hand, when partial shade conditions increase, the temperature does not affect the decrease in solar panel output power. The greater the intensity of partial shade produced by the solar panel, the lower the output power. However, for short periods of partial shade, the output power produced tends to be more stable than under normal conditions.

Abstract

Photovoltaic is employed to support the national electricity energy blending policy as an additional component of renewable energy. Efficient energy monitoring is utilized to understand the efficiency, energy requirements, and performance of Photovoltaic. This research aims to analyze the performance of a standalone Photovoltaic system. The study considers various parameters such as PV size, load, and charge controller. Additionally, it involves designing a monitoring tool used for the analysis of Photovoltaic performance. Performance measurements are conducted by comparing Photovoltaic systems of different sizes. Furthermore, performance measurements are compared with different types of charge controllers. To assess performance, solar energy is measured at various times using a solar power meter. The solar power meter is then used to analyze the research's performance. Energy monitoring involves measuring voltage, current, power, and energy using Atmega328p. The measurement data is utilized to evaluate system efficiency and design future systems. Monitoring is carried out directly on Photovoltaic systems in the equatorial region. This research measures solar energy, energy produced by Photovoltaic systems, and energy consumed by loads. Energy monitoring focuses on observing solar and Photovoltaic energy during sunlight hours (morning-evening). The analysis results can be utilized for designing efficient Photovoltaic systems in the future..

Abstract

The increasing adoption of solar power systems has highlighted the need for effective overcurrent and overvoltage protection to ensure operational reliability and safety. This study aimed to implement and evaluate a protection system for a 10 × 100 Wp solar power plant at PPYD Al-Ikhlas, Singosari, Indonesia. The research employed an experimental approach, including testing Miniature Circuit Breakers (MCBs), Surge Protection Devices (SPDs), and grounding systems. MCBs were evaluated using an injection current tester to assess their tripping characteristics, while SPDs were tested for continuity using a multimeter. The grounding system was examined with an earth tester to measure its resistance before and after implementing a parallel electrode configuration. The results indicated that the installed protection system significantly enhanced safety, with MCBs effectively disconnecting excessive currents as per IEC 60898-1 standards. The SPD successfully mitigated transient voltage surges, and the grounding system reduced resistance below 5 Ω, complying with PUIL 2020 standards. These findings support previous studies on electrical protection and grounding efficiency, emphasizing the need for tailored solutions in small-scale solar systems. Future research should explore real-time monitoring with IoT-based systems and optimize grounding configurations for high-resistivity soils. The proposed protection approach contributes to enhancing the resilience of distributed solar power installations.

Abstract

Smallholder goat farmers in Jabung Village, Malang Regency, face significant challenges related to manual milking, including prolonged labor time and limited access to appropriate technologies. This study aimed to evaluate the effectiveness of a portable, battery-powered milking device in enhancing labor efficiency, technical knowledge, and economic outcomes for these farmers. Using a Participatory Action Research (PAR) approach, the research involved 50 farmers through a baseline survey, co-design process, a six-hour training session, and follow-up evaluation. The results showed that the device reduced the average milking time for five goats from 64 ± 4 minutes to 55 ± 3 minutes, indicating a 14% improvement. Farmers’ technical knowledge also increased significantly, from 42% to 85% after training. User satisfaction was high, averaging 4.2 out of 5, with women reporting greater ergonomic benefits. Economically, the device demonstrated an eight-month payback period based on a milk price of 12,000 Indonesian Rupiah per liter. Furthermore, 80% of farmers were able to operate the device independently after training. These findings suggest that the device holds strong potential to improve smallholder productivity and resilience, contributing to Sustainable Development Goals (SDGs) 2 and 7. However, limitations include the small sample size and the absence of data on milk quality, indicating the need for broader, long-term research.
