Berkurangnya produksi energi fosil terutama minyak bumi serta komitmen global dalam pengurangan emisi gas rumah kaca, mendorong Pemerintah untuk meningkatkan peran energi baru dan terbarukan secara terus menerus sebagai bagian dalam menjaga ketahanan dan kemandirian energi. Energi listrik surya dihasilkan oleh komponen yang disebut panel surya. Komponen ini mengubah energi dari sinar matahari menjadi energi listrik. Reflektor Surya yang digunakan pada panel surya adalah cermin. Cermin datar adalah cermin yang memiliki permukaan datar seperti garis lurus, dimana salah satu permukaannya dilapisi dengan logam pemantul sehingga permukaan cermin datar dapat memantulkan lebih dari 95 persen cahaya yang mengenainya. Pada penelitian ini dilakukan penambahan reflektor pada panel surya di sisi kanan dan kiri serta depan dan belakang dilihat dari posisi normal panel surya. Reflektor pada panel surya dibentuk dengan sudut 60, 70 dan 80 derajat. Reflektor berfungsi untuk mengoptimalkan cahaya di sekitar panel surya dan memfokuskan cahaya ke arah panel surya sehingga menghasilkan daya output yang lebih besar. Panel surya terbaik adalah yang menggunakan sudut 80° untuk menghasilkan tegangan dan daya rata-rata dalam tiga hari, masing-masing 18,26 V dan 54,68 W. Tegangan terbesar terjadi di hari ke-2 dengan sudut 80° yaitu 18.93 V.

The utilization of solar energy through photovoltaic (PV) systems continues to face efficiency challenges due to variations in light intensity and the sun’s changing position throughout the day. Static PV panels perform optimally only when positioned perpendicular to incoming sunlight, necessitating an adaptive tracking mechanism. This study designs and evaluates a low-cost dual-axis active solar tracking system employing light-dependent resistors (LDRs) and an Arduino Uno microcontroller to automatically adjust the panel’s orientation in response to solar movement. A five-day performance test was conducted comparing the dual-axis tracker with a fixed-panel system, measuring output power, voltage, current, and overall efficiency. Results show an average power increase of 7.41 W and an efficiency gain of 1.63% with the tracking system. A peak efficiency of 13.49% was recorded under low irradiance conditions, indicating the system’s ability to maintain optimal performance despite fluctuating light. These findings suggest that dual-axis tracking offers a practical and effective solution for enhancing PV efficiency, especially in regions with significant daily variations in solar intensity.Pemanfaatan energi surya melalui sistem fotovoltaik (PV) masih menghadapi tantangan efisiensi akibat variabilitas intensitas cahaya dan posisi matahari sepanjang hari. Panel PV statis hanya menghasilkan daya maksimum saat tegak lurus terhadap arah sinar matahari, sehingga diperlukan sistem pelacakan yang adaptif. Penelitian ini merancang dan menguji sistem pelacak surya aktif dua sumbu berbiaya rendah dengan menggunakan sensor light-dependent resistor (LDR) dan mikrokontroler Arduino Uno, yang secara otomatis mengatur orientasi panel mengikuti pergerakan matahari. Pengujian dilakukan selama lima hari untuk membandingkan kinerja sistem pelacak dengan panel statis, menggunakan parameter daya keluaran, tegangan, arus, dan efisiensi. Hasil menunjukkan peningkatan daya rata-rata sebesar 7,41 W dan efisiensi sebesar 1,63% pada sistem pelacak. Efisiensi tertinggi sebesar 13,49% dicapai pada kondisi iradiasi rendah, mengindikasikan kemampuan sistem dalam menjaga performa optimal di bawah pencahayaan yang tidak stabil. Temuan ini menunjukkan bahwa pelacak dua sumbu merupakan solusi praktis dan efektif dalam meningkatkan efisiensi sistem PV, terutama di wilayah dengan fluktuasi harian intensitas surya yang signifikan.

The Indonesian government's initiative to meet a renewable electricity supply 2050 of around 100% and its ecological benefits, has an impact on the big challenge where the increasing number of photovoltaic (PV) systems due to high power input and risks to electricity network security conditioned sunny weather for a long time. This research aims to provide predictable power output for network operators, thereby enabling longer planning periods and increasing the protection of the national operational network. Independent consumption by household consumers will impact household energy behavior and affect the security of the electricity network. Consumption itself provides an incentive to increase the cost of energy use which will be much higher than the compensation received, so software is needed which can support PV system prediction patterns. This pattern will close the gap in software development in the process of implementing optimization and configuration based on PV estimates. The consumption planning optimization algorithm itself validates the predetermined scenario optimization process. This research contributes to the efficiency and stability of energy use in households.

Secara sosio-ekonomi, penerapan teknologi ini berhasil menekan biaya operasional air masyarakat hingga menjadi Rp0 per KK per bulan. Guna menjamin keberlanjutan program jangka panjang, telah dibentuk tim pengelola desa mandiri yang beranggotakan lima orang personel terlatih. Kata kunci: pompa air tenaga surya; penyediaan air bersih; energi terbarukan; kualitas air; pemberdayaan masyarakat. Abstract Gorat Pallombuan Village in Samosir Regency is an agricultural community facing accessibility constraints and a crisis in clean water provision. Poor water quality, characterized by turbidity and odor, coupled with a high reliance on fossil fuel-powered water pumps and the absence of a structured management system, has led to infrastructural degradation and a deficit in skilled maintenance personnel. As a solution to these challenges, an integrated, efficient, and eco-friendly solar-powered water pumping system was implemented. The system is powered by a 550 Wp solar panel to eliminate dependence on fossil fuels and is integrated with a two-stage filtration unit for water purification. Additionally, a multi-tiered reservoir infrastructure was installed to optimize water distribution to elevated residential areas. The program's implementation framework encompassed community socialization, technology installation, technical operational training, and a three-month mentoring period. The results demonstrate the successful provision of a sustainable clean water supply capable of serving 22 households. The system's performance is evidenced by a significant improvement in water quality, indicated by a reduction in Total Dissolved Solids (TDS) from 305 mg/L to 98 mg/L. Socioeconomically, the application of this technology successfully reduced the community's operational water costs to IDR 0 per household per month. To ensure long-term program sustainability, an independent village management team comprising five trained personnel was established. Keywords: solar water pump; clean water provision; renewable energy; water quality; community empowerment.

Thermal Energy Storage (TES) systems are essential for managing low-grade heat in renewable energy applications. This study evaluates the impact of flow rate and heating power on thermal stratification and efficiency within a 30-liter TES unit. Using an AI-assisted simulation framework, the system's performance was analyzed across varying flow rates (0.3–0.9 LPM) and heater capacities (1.5–2.0 kW). Results indicate that lower flow rates (0.3–1.2 LPM) effectively preserve stratification, whereas higher rates induce thermal mixing. While charging efficiency generally decreases as target temperatures rise, it improves significantly with higher heater power. Notably, the configuration using a 0.7 LPM flow rate and 2.0 kW heater achieved a peak efficiency of 78% while maintaining stable thermal layering. This research demonstrates how AI-driven modeling can optimize charging behavior, providing critical insights for the design and thermal management of compact TES systems in low-grade heat applications.
