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

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 growing demand for electricity in the Province of Bali is still largely dominated by the use of fossil fuels and coal. This reliance on conventional energy sources contributes to carbon dioxide (CO₂) emissions and greenhouse gases, which in the long term have a negative impact on the environment. To reduce this dependency, the utilization of renewable energy sources such as Solar Power Plants (PLTS) offers an effective and environmentally friendly solution. The Lecture Building at Udayana University was selected as the study object due to its relatively high electricity consumption. The PLTS system design for this building was based on the available roof area, utilizing all four roof sides. Each side is equipped with 32 solar modules rated at 670 Wp per unit, one inverter with a capacity of 25 kW, and 16 battery units each with a capacity of 200 Ah. The system design was simulated using PVSyst software, and with a total installed capacity of 85.76 kWp, the system is capable of generating approximately 515.8 kWh of electricity per day.

Abstract

The ever-increasing demand for electrical energy demands alternative, environmentally friendly, and sustainable energy sources. Conventional batteries generally rely on synthetic chemicals that have the potential to pollute the environment. One solution that is beginning to be developed is the use of organic waste as an electrolyte source in bio-batteries. This review article discusses the potential of orange peel, fruit, and vegetable waste as a natural electrolyte containing organic acid compounds, particularly citric acid (C₆H₈O₇), as well as mineral acids that can decompose into ions in solution, thus conducting electricity. Various research results show that the acid and water content of organic waste can produce a potential difference when paired with dissimilar metal electrodes, thus generating an electric current. In addition, the pH characteristics and natural electrolyte content of the waste indicate its suitability as a substitute for hazardous chemicals in batteries. Thus, the use of orange peel, fruit, and vegetable waste has the potential to become an environmentally friendly bio-battery innovation that can support efforts to reduce dependence on conventional batteries while contributing to sustainable organic waste management.
