Abstract

Water is an essential requirement for agricultural land and can be obtained from various sources depending on its geographical location. The Keliki Village Farmers Group in Subak Malikoda faces the challenge of drought, resulting in a shortage of water supply during the dry season. In this research, a Solar Irrigation Pump (SIP) with a solar tracker system is designed to pump groundwater with the aim of enhancing irrigation water supply for Subak Malikoda during the dry season. The solar-powered irrigation pump system design consists of an 18.5 kW submersible pump coupled with a 23.1 kWp PV system using 60 monocrystalline solar modules equipped with a solar tracker and a 30 kW inverter. Based on the analysis conducted, the PVSyst results for the SIP without a solar tracker show that the pump can operate for 6,067 hours with an average water discharge of 274.9 m3/day. This is based on the received global effective irradiation of 1765.1 kWh/m2 in one year. However, with the use of the solar tracker system, the pump can operate for 6,933 hours with a water discharge of 305.2 m3/day and global effective irradiation of 1963.8 kWh/m2 in one year. The analysis concludes that the SIP with a solar tracker system can operate optimally and fulfill the water discharge requirements of Subak Malikoda. This makes the solar tracker system an effective solution to enhance the water supply for Subak Malikoda during the dry season.

Abstract

The islands of Nusa Penida, Nusa Lembongan, and Nusa Ceningan are some of the famous tourist destinations in Bali. The growth of tourism in the area has increased the demand for electrical energy. PLN is committed to improving infrastructure by building a solar power plant and BESS in Nusa Penida. This research aims to analyze the impact of implementing PLTS and Battery Energy Storage Systems (BESS) on the frequency of the electricity system in Nusa Penida. This research uses a simulation with two scenarios in three different conditions. Scenario 1 is simulated by releasing the Cogindo generating unit from the Nusa Penida electricity system with three conditions, namely an electricity system without PLTS and BESS, an electricity system with PLTS, and an electricity system with PLTS and BESS. Scenario 2 is simulated by removing the Ceningan feeder from the Nusa Penida electricity system with the same three conditions. Simulations were carried out to determine the effect of PLTS and BESS on frequency changes. The simulation results show that frequency changes are still within the limits regulated by the Minister of Energy and Mineral Resources Regulation Number 20 of 2020.

Abstract

Electric energy can be utilized as an alternative to replace oil-based fuel. One of the steps to address the energy crisis issue is through the Energy-Efficient Car Competition (KMHE), which emphasizes the energy efficiency of vehicles. The WEIMANA team from Udayana University has participated in the Urban Concept category by designing a vehicle named Agnijaya. Agnijaya is an electric-powered car that uses a Brushless DC (BLDC) electric motor. Currently, the Agnijaya electric car does not have a continuous monitoring system for voltage, current, and speed. The research aims to design a monitoring system for the Agnijaya electric car using an SD card as a data storage medium for voltage, current, and speed data. This system is controlled using an Arduino Mega 2560 Pro Mini microcontroller board as the data processor and an SD card as the data storage medium. The monitoring system for the Agnijaya electric car has been successfully designed, built, and tested for voltage, current, and speed values. Testing was conducted by comparing the measured values of voltage, current, and speed, all of which were stored on the SD card. The results of the analysis indicate that the percentage deviation in battery voltage measurement is 0.85%, the deviation in battery current measurement is 0.23%, and the deviation in speed measurement is 0.32%.

Abstract

Sultan Muhammad Salahuddin Bima Airport is one of the few airports in Indonesia that has PLTS as a supplier of electrical energy. The existence of PLTS at each airport is a concern for further analysis, so that the potential for electrical energy production from PLTS can be optimal. So the solar module which is the main component of PLTS is very important to pay attention to cleanliness from dirt or dust that can reduce the efficiency and electricity production of PLTS. The measurement of PLTS energy production at Sultan Muhammad Salahuddin Bima Airport before cleaning was 567.56 kWh and after cleaning it was 576.86 kWh. In this measurement, cleaning was carried out on a series of 1 Inveter with a total of 100 solar panels. There is a change in energy production from the measurement results. This condition is due to solar panels that have not been cleaned for 1 year. So that the percentage increase in PLTS energy production at Sultan Muhammad Salahuddin Bima Airport is 1.63%.

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.
