Abstract

The number of PLTS installed on factory rooftops is growing. In Indonesia, the Directorate General of New, Renewable Energy estimates a total renewable energy potential of 442 GW, with solar energy holding the greatest potential. The performance of the PLTS system needs to be considered to ensure good performance in generating electricity. This research focuses on the rooftop on-grid PLTS system in a Pharmaceutical Company located in the PT Jakarta Industrial Estate Pulo Gadung area, with a capacity of 463.25 kWp. Electricity generation potential is modeled using PVSyst software for examination of the PLTS system's performance. For the period of one year, from November 2021 through October 2022, the PLTS system's performance characteristics are determined. These include the Yield Factor (Yf), Reference Yield (Yr), Performance Ratio (PR), and Capacity Utilization Factor (CUF). According to the model, the 463.25 kWp on-grid rooftop PLTS system may generate up to 629,550 kWh of power each year. The values of the PLTS system performance parameters are as follows: Yield Factor (Yf) is 1,358.99 kWh/kWp, Reference Yield (Yr) is 1,730.6 kWh/kW, Performance Ratio (PR) is 78.56%, and Capacity Utilization Factor (CUF) is 15.73%. Meanwhile, the actual electricity production for one year is 570,724.82 kWh, with the following performance parameters for the PLTS system: Yield Factor (Yf) is 1,232 kWh/kWp, Reference Yield (Yr) is 1,642.85 kWh/kW, Performance Ratio (PR) is 76.12%, and Capacity Utilization Factor (CUF) is 14.26%. There is a difference between the PVSyst software simulation and the actual results, which are 58,825.18 kWh, 126.98 kWh/kWp, 87.75 kWh/kW, 2.44%, and 1.47% respectively.

Abstract

According to the Directorate General of EBTKE, Indonesia has a great deal of untapped potential for PLTS development because the equator passes through the country. Furthermore, the use of PLTS can mitigate the negative effects of carbon emissions caused by conventional power plants' reliance on coal. This research aims to quantify the savings in carbon emissions from PLTS deployment and to conduct an economic analysis of PLTS deployment by considering its Life Cycle Cost (LCC), Levelized Cost of Energy (LCoE), Net Present Value (NPV), and Payback Period (PBP). Profitability Index (PI) and Internal Rate of Return (IRR) for a pharmaceutical firm located in East Jakarta's PT Jakarta Industrial Estate Pulo Gadung. The results of the analysis that has been carried out obtain a total reduction in carbon emissions due to the use of PLTS when compared to JAMALI's electricity carbon emissions of 479.4 tons CO2eq in a year. The use of PLTS affects savings in paying electricity bills of IDR 591,145,354.06 each year and from the economic analysis using the methods (LCC, (LCoE), (NPV), (PBP), (IRR), and (PI) it is obtained that the feasibility The investment in PLTS development in this company is considered feasible.

Abstract

The design of Off-Grid PV at Adidaya Workshop as an additional electrical energy supplier is based on the load requirements used for equipment and operations at the workshop. In addition to requests from the company itself, the design of Off-Grid PV is carried out to supply electrical energy to essential loads and other educational purposes. The Off-Grid PV design was carried out with the first step of field observations at Adidaya Workshop, measuring the roof area, daily electricity load profile with a Power Quality Analyzer measuring instrument, and calculating the capacity requirements of the Off-Grid PV system according to the Adidaya Workshop load. The Off-Grid PV design was carried out with 4 scenarios based on variations in solar panels and batteries. Researchers calculated the capacity of the PV system and used PVSyst software as a design simulation so that a report was obtained based on field data. In the simulation results with PVSyst, the best performance ratio is obtained which is worth 68.3% obtained from scenario 3 with a variation of 600 Wp solar panels and 540 Ah batteries and the largest yield energy output is obtained from scenario 4.

Abstract

Oka Jamur Bali is one of the oyster mushroom cultivation farmers. Lack of efficiency in regulating temperature and humidity in mushroom barns is an important factor in the growth of mushroom fruiting bodies. This condition requires an innovative solution to regulate and monitor temperature and humidity in the barn area. This research aims to build a prototype using Arduino UNO, ESP32, DHT11, pump and Internet of Things (IoT) technology. The monitoring system design uses Arduino UNO, NodeMCU ESP32, DHT11 and DC pump with 12V voltage. Arduino UNO functions as a control system to manage and control the temperature and humidity parameters of the mushroom barn environment with the DHT11 sensor used to accurately measure temperature and humidity. The combination of NodeMCU ESP32 and Arduino UNO aims for monitoring through the ThingSpeak platform which can be accessed with a smartphone connected to the internet network. Based on the results of the prototype of the automatic temperature and humidity control system, the system is able to measure the environmental conditions of the mushroom barn with humidity measurement results in the range of 79% - 82% and the average temperature during the test reached 29.35°C. The application of the system was able to reduce the temperature by 2.28% with an average temperature of 28.19°C and increase the relative humidity by 6.27% with an average humidity of 81.1% in the mushroom barn area. The results of income between the income generated by using the automatic temperature and humidity control system tool and the income of farmers without using the tool increased by Rp. 16,416.
