Abstract

The scarcity of available land does not impede the development of productive activities. Hydroponic vegetable cultivation emerges as a viable solution for maximizing the utilization of limited land. Hydroponic vegetables have been shown to possess enhanced nutritional value and to be free from pesticides. The cultivation of hydroponic vegetables has the potential to augment family income. The objective of this Community Service Program (CSP) is to empower Family Welfare Empowerment (FWE) members in Babadan Village through counseling and mentoring. The hydroponic vegetable cultivation media utilizes readily available household items. The CSP is a multifaceted program that includes a location survey, planning, counseling, mentoring, and evaluation. The results of the CSP showed that 80% of the participants understood the hydroponic vegetable growing system. After the activity was completed, CSP participants practiced hydroponic vegetable cultivation independently. The principle of Reduce, Reuse, Recycle (3R) is applied as an operational saving step. This CSP activity improves participants' skills and supports economic independence and awareness of the importance of healthy food. The future expansion of this CSP initiative entails the diversification of hydroponic plant species, the establishment of a hydroponic community, and enhanced access to marketing opportunities for produce. The integration of local markets and digital platforms is anticipated to be optimized.

Abstract

The development and development of new renewable energy has become increasingly widespread recently, one of the most widely used is solar panels. The biggest disadvantage of installing solar panels is that they are not able to follow the movement of the sun so that the power output produced is less than optimal. A solar tracker is a device used to optimize the absorption of sunlight by solar panels by following the movement of the sun. However, the use of sensors on solar trackers often requires quite complicated manufacturing. Therefore, this research aims to design a solar tracker without sensors in photovoltaic (PV) systems. The method in this research is to compare the power produced by solar panels with and without solar trackers based on IoT (Internet of Things) case studies at the UNIPMA Integrated Lab. Data collection was carried out in real time over a period of 3 days starting at 09.00 WIB with a solar panel tilt of 45° until 15.00 WIB with a solar panel tilt of 135°. The results of measurements using a solar tracker on photovoltaic (PV) showed an average current of 0.74 amperes (A), an average voltage of 18.7 volts (V), and an average power output of 14.4 watts. (W). Meanwhile, measurement results without a solar tracker showed an average current of 0.6 amperes (A), an average voltage of 17.9 volts and an average power output of 11.04 watts (W). So, the power produced with a solar tracker is more optimal than without a solar tracker.

Abstract

The development of digital technology and the increasing need for energy are challenges as well as opportunities in community empowerment efforts, especially in rural areas. Providing targeted and applicable training on the use of digital technology and energy savings based on solar panels is a solution to overcome these problems. The training was conducted on 25 PKK mothers in the Brendil Ngawi hamlet. The results of this training showed an increase in knowledge about digital technology and solar panels by more than 50% of the total participants. It is hoped that after this training, PKK mothers will be able to apply this knowledge in their respective household lives so that they can form independent and self-sufficient families.

Hasil menunjukkan energi harian berkisar 40,2–69 kWh dengan rata-rata 52,9 kWh, total produksi 3.232,2 kWh, daya puncak 9,3 kW, efisiensi inverter 98–100%, serta FF rata-rata 0,792. Nilai PR mencapai 95% pada September dan 98% pada Oktober, dengan rata-rata 96%. Temuan ini membuktikan bahwa sistem PLTS beroperasi stabil, efisien, dan layak dijadikan model penerapan energi terbarukan di sektor publik, sekaligus dasar strategi pengembangan energi berkelanjutan di Indonesia. Abstract The increasing demand for electricity requires diversification of energy sources through the utilization of renewable energy. Solar energy is considered highly potential in Indonesia, particularly in East Java, which has high solar radiation throughout the year. This study aims to evaluate the performance of an on-grid Solar Power Plant (PLTS) installed at the Jasa Marga Ngawi–Kertosono Office, East Java. The research was conducted from September to October 2024 using a descriptive quantitative approach. The instruments employed included a multimeter to measure voltage and current, a data logger to record power and environmental conditions, and Microsoft Excel software for data processing. The dataset consisted of primary field measurements and secondary data of daily historical power records. Analysis was carried out using descriptive statistics, data visualization, comparison between actual and theoretical power, and evaluation of key performance indicators such as peak power, conversion efficiency, fill factor (FF), and performance ratio (PR). The results showed daily energy production ranging from 40.2 to 69 kWh with an average of 52.9 kWh, total output of 3,232.2 kWh, peak power of 9.3 kW, inverter efficiency of 98–100%, and an average FF of 0.792. The PR reached 95% in September and 98% in October, with an average of 96%. These findings confirm that the PLTS system operates stably, efficiently, and can serve as a model for renewable energy implementation in the public sector, while providing a basis for strategies to optimize sustainable energy development in Indonesia.

Abstract

The development of renewable energy technology is getting more rapid, one of which is using solar energy through photovoltaic (PV) systems. A solar tracker is a device used to optimize the absorption of sunlight by solar panels by following the sun's movement. However, using sensors on solar trackers often requires quite complicated manufacturing. Therefore, this research aims to design a sensorless solar tracker on a photovoltaic (PV) system. The method in this study is to attach the actuator motor to the solar panel frame and move it automatically using Arduino Uno. Data was collected in real-time within three days using three different power supplies. Data collection started at 09.00 WIB with a solar panel tilt of 45° and went to 15.00 WIB with a solar panel tilt of 135°. The results of measurements using a solar tracker on photovoltaic (PV) obtained an average current of 0.74 amperes (A), an average voltage of 18.7 volts (V), and an average power of 14.4 watts (W).
