Abstract

The increasing demand for electricity, high prices, and lack of fossil fuels are forcing local community to look for renewable energy sources. Villages in palm oil mills have large volumes of biomass waste, especially palm oil mill effluent (POME), which causes environmental and health issues. This study proposed a hybrid renewable energy system consisting of solar photovoltaic (PV) and biogas to provide sustainable electrification for an off-grid village. To minimize the environmental impact and availability of the applied technology, the PV panels were incorporated with a biogas-fueled generator. Simulation experiments were carried out using the HOMER software for an average daily demand of about 159.65 kWh/day and a peak load of 20 kW. The investigation was emphasized to find the optimal PV/biogas system to serve the village community considering electrical, economical, and environmental aspects. Subsequently, a standalone biogas system was used as the base case. The proposed configuration consisted of a biodigester, a biogas-fueled generator, PV panels, an inverter, and batteries with 8.5 hours of autonomy to produce electricity of around 67,216 kWh/year. The results demonstrated the technical and economic feasibility, as well as the environmental benefits of a PV/biogas system for generating electricity for the off-grid village community.

Abstract

Currently, the use of energy sources as fuel for power plants still heavily relies on fossil fuels or, in other words, non-renewable energy sources that will gradually deplete and undoubtedly have environmental consequences. This research is conducted in an area that is geographically distant from the PLN (State Electricity Company) grid. Recognizing the need for increased use of Renewable Energy (EBT) and in line with the national target for 2025 set by the Ministry of Energy and Mineral Resources (ESDM), it is expected that the use of EBT can reach 23%. One of the efforts in developing EBT in areas that are not covered by the PLN electricity network is through Solar Power Plants (PLTS). The objectives of the upcoming research include calculating the cost per kilowatt (kW), determining the investment cost for the planned PLTS, and assessing the PLTS capacity to meet the energy demand in Dusun Molo, Bengkayang Regency. Based on the calculation results, the estimated daily electricity demand in Dusun Molo, Seren Selimbau Village, supplied by the PLTS, is 224,223 kWh/day. The power generated by the PLTS to meet the needs of Dusun Molo is 53,283 Wattpeak, while the planned power generation by the PLTS to meet Dusun Molo's requirements is 76,000 Wattpeak. The investment cost for the construction of the PLTS in Dusun Molo is IDR 3,213,751,000, including an 11% Value Added Tax (VAT). After the calculations, the Cost of Energy (COE) or price is determined to be IDR 2,972.00/kWh. This research provides an estimate of the investment cost for the construction of a PLTS in Dusun Molo, Bengkayang Regency.

Apart from that lectures at the Tanjungpura University Joint Lecture Building, several inappropriate electrical energy use behaviors were also found. Among them are the use of lighting during the day, air conditioning is turned on when the learning is empty, room facilities are lit when the room is not used and others. As a result, the allocation of high electricity costs in the Untan Joint Lecture Building. To avoid this problem, it is necessary to plan the use of electronic access cards in the Untan Joint Lecture Building. This electronic access card is a tool that functions to cut off or connect electricity to an area or room. So this planning is carried out so that it will provide insight into how to overcome these problems. In this planning, several calculations are carried out, namely total load, energy consumption, energy savings, electrical energy costs, and payback period at the Tanjungpura University Joint Lecture Building. From the results of the calculation of the effect can be seen after the installation of electronic access cards, which can produce large savings, with energy consumption costs after savings in Building A for a month amounting to Rp. 4,203,147,667. And the period needed to cover investment expenditures is the longest for 4 months and the fastest is less than 1 month.

Abstract

Photovoltaic power plants (PVPs) are an environmentally friendly renewable energy source that can ensure sustainable electricity supply for schools while reducing dependence on traditional energy sources, which are not only expensive but also often harmful to the environment. Although the construction of solar power plants requires a large initial investment, technical planning such as the location of solar panels, system capacity, and integration into the existing power grid are important factors that need to be considered. This solar power plant is built on the roof of an office building that has the longest roof at 34 meters. It will be built using monocrystalline solar panels with a capacity of 670 Wp, an inverter with a capacity of 5.000 W, a solar charge controller with a capacity of 38 A, and lithium-ion batteries with a capacity of 400 Ah. This solar power plant will be planned to operate for 25 years with generated energy of 10.063 Wp.

Abstract

Solar energy as a non-fossil alternative energy source has become the best choice to overcome the problem of energy demand in most countries in the world. There are two different techniques to convert solar energy: photovoltaic (PV) panels to produce electricity and thermal collectors to generate heat. The two technologies can be combined to provide electrical and thermal energy either simultaneously or separately. In order to optimize the performance of a hybrid photovoltaic-thermal (PVT) solar air heater, it is necessary to collect experimental data on solar irradiation and temperature. This paper emphasized the development of a PVT energy system for hot air production in a temperature range of 50-55 °C. Additionally, experiments were constructed to monitor the information acquired from the proposed PVT solar air heater and the environment, such as hot air temperature, ambient temperature, and solar irradiation. The real-time monitoring system was set for five sample days. A microcontroller unit was used to control the hot air temperature and save the measurement data into memory. The experimental results showed that the proposed PVT solar air heater is capable of maintaining a certain level of hot air temperature throughout the day and night.

Abstract

Grain drying environmental parameters are an important issue throughout the paddy grain production process. A real-time monitoring system requires rapid, online, and accurate measurement results. In the paddy grain drying process, the heated air velocity, temperature, relative humidity, and moisture content have to be carefully monitored and maintained to ensure product quality and safety. This study aimed to propose a real-time paddy grain drying and monitoring system using a long-range internet of things (LoRa-IoT). The real-time monitoring system consisted of sensors, LoRa, and IoT platforms. The LoRa end node and gateway were utilized as a wireless radio communication platform of IoT for long-distance signal transmission. From the experiment, the gateway received data from the end node at a distance of 2 km with a time on air (ToA) of 981 ms. As a result, the proposed monitoring system succeeded in measuring and recording the heated air velocity, temperature, and relative humidity data during the paddy grain drying process from 25% moisture content down to 14%. Regarding moisture content, the accuracy of real-time monitoring information was confirmed with a direct measurement method, resulting in a root mean square error (RMSE) of 6.17%.
