Abstract

A battery, also known as an accumulator, is an electrical cell that can reverse an electrochemical process with high efficiency. It is essential in the use of electrical systems as storage devices. It has two critical parameters: current and voltage. These parameters can affect the battery's behavior, which leads to battery usage. As a result, a battery monitoring instrument is required to monitor the battery's current and voltage while it is in use. The researchers designed a monitoring instrument with an Arduino Pro Mini 5V microcontroller as the main processor, INA219 as a current and voltage sensor, RTC DS3231 as a time reader, micro SD card module as a data logger, and OLED SH1106 to display the current, voltage, and time readings. The calibration of the INA219 sensor has a current reading accuracy of 91.43% and a voltage reading accuracy of 99.87%. RMSE was measured at 227.65 mA and 0.0146 V. The device was tested with a BSB DB 12-55Ah battery connected to 30W PJU lamps. In the results of this test, we experienced voltage drop and current ripple in the battery performance. The battery usage capacity was 49.71 Ah. Based on this research, the device built can monitor battery conditions.

Abstract

New Renewable Energy (EBT) is an environmentally friendly energy source that can be continuously renewed. One of the EBT technologies that is widely used is solar panels, which utilize solar energy as an electrical resource. This research aims to analyze battery charging patterns based on using solar panels with capacities of 5WP, 10WP, and 20WP, as well as charging modules such as TP4056 and INA219 sensors to monitor voltage and amperage. The research results show that solar panels with a capacity of 20 WP have faster charging capabilities compared to solar panels with a capacity of 5 WP and 10 WP. The average battery charging time in sunny weather is around 3 hours, while the battery charging time in cloudy weather is around 6 hours. This shows that solar panels with higher capacity can increase the efficiency of the battery charging process. Keywords : New Renewable Energy, Solar Panels, Lithium-Ion Batteries, INA219 Sensors

Abstract

The charging speed of lithium-ion batteries depends on the applied current, with higher currents resulting in faster charging.  However, higher currents can increase the surface temperature, potentially damaging components or causing safety hazards. This study measured the surface temperature of lithium-ion batteries using the DS18B20 sensor. The TP4056 module was used for currents of 880.9 mA, 982.30 mA, and 1134.40 mA, while the TP5100 module was used for a current of 1323.80 mA. Charging at 1328.38 mA required the shortest time, approximately 3-4 hours. Temperature measurements showed no significant increase across the range of 880.0-1328.38 mA. For 982.30 mA, the first and second measurements recorded maximum temperatures of 34.4 °C and 36.2 °C, respectively. In the third measurement at 1328.38 mA, the maximum temperature reached 35.5 °C. Overall, the temperature variations remained below the maximum safe limit for lithium-ion battery charging.

Abstract

This research aims to analyze the comparison of power output between Polycrystalline solar panels with and without the use of mirror reflectors. The growing demand for sustainable energy sources necessitates ongoing efforts to enhance the efficiency of photovoltaic (PV) technology. In this study, a comparative experimental design was implemented over a two-day period, utilizing two identical solar panel configurations: a Reflector Equipped-Solar Panel (RESP) and a Solar Panel Without Reflector (WRSP). The electrical parameters of both configurations, including voltage, current, and power output, along with temperature, were continuously monitored and analyzed. The results indicate that the RESP consistently outperformed the WRSP. On average, the RESP produced 28–35% higher electrical current, which directly translated into a 25–32% increase in power output compared to the WRSP. The peak power of the RESP reached 21.3 W, whereas the WRSP peaked at 16.2 W. Although the RESP operated at a higher temperature (approximately 5–7 °C greater than WRSP), the power gain from increased irradiance effectively outweighed the thermal losses. These findings provide strong empirical evidence that reflective augmentation is a viable and cost-effective method for enhancing the performance of standard solar panels, offering valuable insights for maximizing renewable energy harvesting.

Abstract

Keterbatasan sarana praktikum di sekolah dasar sering menjadi kendala dalam menyampaikan materi sains secara menarik dan aplikatif, terutama pada konsep rangkaian listrik. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pemahaman konsep rangkaian listrik seri dan paralel pada siswa kelas VI SD Negeri 010 Bukit Bestari melalui pembelajaran interaktif berbasis simulasi dan praktikum langsung. Metode pelaksanaan meliputi penyampaian materi pengantar, demonstrasi simulasi menggunakan PhET Circuit Construction Kit DC, serta kegiatan praktikum merangkai rangkaian listrik sederhana yang dipandu dengan Lembar Kerja Siswa (LKS). Siswa dilibatkan secara aktif dalam mengamati, merangkai, dan mendiskusikan hasil percobaan sehingga proses belajar menjadi lebih kontekstual dan bermakna. Evaluasi kegiatan dilakukan menggunakan angket respon yang diberikan kepada siswa dan guru untuk menilai efektivitas pelaksanaan, kebermanfaatan materi, serta pengalaman belajar yang diperoleh. Hasil angket siswa menunjukkan nilai rata-rata sebesar 3,7 yang berada pada kategori sangat baik, sedangkan penilaian dari guru berada pada kategori baik hingga sangat baik. Temuan ini menunjukkan bahwa kegiatan PKM mampu meningkatkan keterlibatan siswa, pemahaman konsep, serta minat terhadap pembelajaran sains. Dengan demikian, kegiatan ini efektif sebagai alternatif pembelajaran berbasis praktikum di sekolah dasar dan memiliki potensi untuk diterapkan secara berkelanjutan.

Abstract

Improving solar panel performance is challenging due to increasing of solar radiation. This study investigates the effect of variations in the angle of the flat mirror reflector on the surface temperature and electrical performance of a 10 Wp monocrystalline solar panel using an ESP32-based data acquisition system with INA219 and DS18B20 sensors. Reflector angles of 45°, 60°, and 75° were tested from 08:00 to 16:00 WIB. The results indicate that the 45° reflector produced the lowest temperature (≈60 °C), the highest average voltage (19.7–20.0 V), maximum current of 120 mA, and peak power of 2.6 W. In contrast, the 75° angle increased the temperature to 72 °C and reduced the electrical output. The study concludes that a 45° reflector angle is optimal for low-power solar panels in hot tropical environments.

Abstract

The fishing community in Kampung Bugis, Tanjungpinang, faces difficulties in accessing electricity at night, which negatively impacts their fishing productivity and increases the risk of accidents at the floating fish cages. Currently, they still rely on generators, while the potential utilization of solar panels as a renewable energy source has not been optimally realized. The main challenge in applying solar panels in this location is the risk of damage due to the harsh maritime environment, as well as concerns about theft due to the lack of adequate protection. This activity aims to improve fishermen's access to electricity by implementing a solar-based lighting system equipped with additional protection to ensure its security. The project involved several phases, starting from problem identification, preparation of tools and materials, installation of solar panels with specially designed iron protection frames, to assistance to ensure that fishermen understand how to use and maintain the system. The installation process was conducted with the fishermen’s involvement, allowing them to maintain the system independently. The results showed that the solar-powered lighting system provided stable lighting at night, reduced the fishermen’s dependence on generators, and increased their productivity in fishing activities. Additionally, the protection provided for the solar panels successfully reduced the risk of damage and theft, which had previously been a major concern. In conclusion, this technological solution effectively improved energy access and the fishermen’s productivity, while providing long-term impact on the sustainability of the floating fish cage operations. For the program's sustainability, regular monitoring and system capacity enhancement are recommended in the future.
