Abstract

The installed PLTS capacity in Bali is currently still 3.44% of the target given by the General National Energy Plan (RUEN) of 108 MWp in 2025. The island of Bali has limited land availability so rooftop PLTS is a solution. The design of the rooftop PLTS was carried out on the roof of the Wisti Sabha Building at I Gusti Ngurah Rai International Airport. The research uses PVSyst simulation software while the investment feasibility method uses the Benefit-Cost Ratio (BCR), Net Present Value and discounted payback period (DPP) methods. Based on the simulation results, the rooftop PLTS capacity is 56.6 kWp with energy production of 98,009 kWh/year. The B-CR value obtained is 2.23, the net present value is IDR 707,436,838.55 and the DPP is 7 years, with a rooftop solar system life of 25 years.

Abstract

Indonesia has a huge potential for solar energy, but its utilization until 2024 only reach 573.8 MWp. The low utilization of solar energy is caused by the limited vacant land for solar power plant installations, especially in urban areas. Rooftop solar power plants are expected to increase the use of solar energy in urban areas. Choosing the right solar panels on rooftop solar is necessary to get the best performing solar panels even though they are placed on limited land. The development of cell arrangement and shape technology in solar panels has resulted in full cell, half-cut cell, and shingled cell solar panels. The weather parameter observed in this study is sunlight radiation. Direct observation was carried out for 4 days at 08.00-16.00 WIB in the Kediri Meteorological Station (BMKG Kediri), with data collection every 5 minutes. The results of the study show that sunlight radiation has a significant influence on the output power of solar panels. The determination coefficient (R2) value of sunlight radiation against solar panels is 0.60 in monocrystalline full cells, 0.65 in monocrystalline half-cut cells, and 0.66 in monocrystalline shingled cells.

Abstract

The increasing demand for electrical energy and the issue of climate change are driving the utilization of renewable energy, one of which is through Solar Power Plants (PLTS). The Province of Bali targets the development of PLTS of 108.2 MW, equivalent to 8.62% of the total solar energy potential of 1,254 MW by 2025. However, land limitations pose an obstacle to the construction of large-scale PLTS. Floating solar power plant design can be a solution to this issue. By utilizing 4,955.32 m² of water surface at the Telaga Tunjung Dam, the Floating Solar Power Plant at Telaga Tunjung Dam has a potential capacity of 141.4 kWp, using 280 Trina Solar modules of type TSM-DEG18MC.20(II) (505 Wp) combined with one SG110CX inverter with a capacity of 110 kW. The annual electricity production of the floating solar power plant, based on Helioscope software, is 201.1 MWh. The economic feasibility parameters used in this study include initial investment cost, Profitability Index (PI), and Payback Period (PP). The analysis results show that the 141.4 kWp floating solar power plant project at Telaga Tunjung Dam has an initial investment value of IDR 1,248,764,582, a PI of 1.26, and a PP of 3.91 years. Therefore, this project is considered economically feasible and contributes positively to reducing CO₂ emissions.

Abstract

Penggunaan energi listrik yang bersumber dari pembakaran energi fosil dalam kegiatan penangkapan ikan telah dilakukan sejak lama di Desa Tablolong. Energi listrik ini bersumber dari genset dan dipergunakan untuk menghidupkan lampu dan alat komunikasi dalam mendukung kegiatan penangkapan ikan. Seiring berjalannya waktu dan penggunaan energi fosil yang terus menerus tentu memberikan dampak yang kurang baik terhadap nelayan dan juga lingkungan di sekitar daerah penangkapan ikan akibat limbah yang dihasilkan. Oleh karena itu maka dilakukan usaha pemanfaatan PLTS untuk mengatasi permasalahan yang ada dengan memanfaatkan energi matahari yang melimpah di Nusa Tenggara Timur guna mendukung ekonomi biru. 24 nelayan diberikan kuesioner dalam pemanfaatan PLTS kemudian dianalisis dengan Uji Wilcoxon untuk mengetahui dampak pemanfaatan PLTS terhadap para nelayan. Hasil tes Wilcoxon menunjukkan perbedaan yang signifikan (nilai p<0,05) dalam kesehatan, keamanan, dan kelestarian lingkungan setelah pemasangan panel surya. Nilai p yang lebih kecil dari 0,001 menunjukkan perbedaan yang sangat signifikan. Hasil ini menunjukkan bahwa PLTS yang digunakan untuk mendapatkan listrik di kapal nelayan di Desa Tablolong memberikan efek yang baik.  Dampak positif dapat dilihat dari peningkatan kesehatan, keamanan dan kelestarian lingkungan yang terjadi setelah pemasangan PLTS di atas kapal.

Abstract

Implementing photovoltaic (PV) systems as direct power sources for motors without batteries is a complex process that requires a sophisticated control mechanism. The crucial aspect of PV systems is the Maximum Power Point Tracking (MPPT) process, which ensures that the installed PV system generates optimal energy output. A recent study has analyzed research related to PV systems supplying power to pump motors, and the results have successfully classified these systems into two main models: the two-stage and the single-stage. The two-stage model involves separate power tracking and load consumption control processes, while the single-stage model integrates power tracking and load consumption control into a single process. A comparative analysis of these two models has revealed that the two-stage model exhibits higher stability due to the separate power tracking and load consumption control processes. Aspects such as the MPPT process, motor power consumption, and the utilization of DC-link capacitors were examined in this study. The findings of this comparative study contribute valuable insights into the effectiveness and stability of two-stage and single-stage models in PV systems supplying power to motors without batteries. The results will significantly interest researchers and practitioners working in Photovoltaic systems and motor control, providing helpful information for designing and implementing more efficient and reliable PV systems.

Abstract

The DH Building of the Electrical Engineering Study Program at Udayana University faces significant challenges in energy efficiency, as it still relies on conventional electrical systems. User negligence, such as forgetting to switch off lights and air conditioners (AC) after use, often results in unnecessary energy waste and increased operational costs. This issue highlights the urgent need for smart solutions capable of automating energy management, reducing waste caused by human error, and supporting the creation of a more efficient and sustainable campus environment. To address this problem, this study designs and implements a smart building system based on the Internet of Things (IoT). The system employs a NodeMCU ESP32 microcontroller as the main processing unit, integrated with a series of sensors including a DHT22 sensor for monitoring temperature and humidity, an MQ2 sensor for smoke detection, a PIR sensor for motion detection, and a PZEM-004T sensor for monitoring energy consumption. Control of electronic devices such as lights and AC units is carried out both automatically and manually through relay modules connected to the system. All sensor data and control functions are accessed via a web interface developed using the Laravel framework and a MySQL database. The testing results indicate that the designed system was successfully implemented and functions as expected. Sensor testing demonstrated high accuracy compared to standard measuring instruments, while the electronic device control system achieved an average response time of approximately 3.6 seconds, proving its reliability. Overall, the system provides a comprehensive solution for energy consumption monitoring and control, while also enhancing comfort and safety in the DH Building, in line with the goals of energy efficiency and facility modernization.

Abstract

The sunlight intensity level requirement for dragon fruit plants is more than 90%, which is essential for the photosynthesis process and the morphological development of the plant. This plant is classified as long-day plant, meaning that it requires at least 12 hours or more of sunlight to reproduce. Dragon fruit farmers utilize artificial lighting as an alternative to sunlight to support the plant's biological processes at night. The energy source is conventional electricity from grid (PLN). The design of an off-grid PV system at the Yosomulyo dragon fruit farm is carried out to support the farm's daily electricity needs. The design begins with field observations to obtain geographic data of the farm, daily electrical load profile data with amperes, calculating the PV system capacity, determining PV system components, and testing the performance of the design with PVSyst simulation. The simulation results of the PLTS design are 70.9% with an inverter variation of 6500 W, solar modules of 550 Wp, batteries of 200 Ah 12 V at a system voltage of 48 VDC, and an autonomy day of 1.
