Abstract

This study aims to optimize the performance of the distribution substation in maintaining the stability of the electricity network, especially in reducing the effects of voltage drops in the Kuta-cane Customer Service Unit (ULP). Significant voltage drops can affect the quality of electricity supply and cause instability that impacts the performance of customers' electrical equipment. This study includes data collection on distribution substations and network conditions, voltage drop measurements at critical points in the network, and voltage distribution simulations using electrical analysis software. Based on the results of the analysis, optimization of the distribution substation was carried out by adjusting the transformer capacity, installing load balancing devices, and rearranging the load distribution to reduce voltage drops. The optimization results showed an increase in voltage stability in the Kuta-cane ULP electricity network, as indicated by a decrease in voltage drops in previously problematic areas. This optimization has proven effective in maintaining distribution stability and improving the quality of electricity supply to customers. This study produces technical recommendations that can be implemented by the Kutacane ULP in maintaining the performance of distribution substations sustainably, so as to improve the reliability of the electricity network in the region.

Abstract

After the Covid pandemic, ecotourism is a tourism concept that prioritizes environmental sustainability and wise use of natural resources. One important aspect in ecotourism development is the use of renewable energy, such as solar panels, to meet energy needs without damaging the environment. This research aims to analyze the potential for renewable energy that can be produced by solar panels to support ecotourism development planning. This research includes collecting secondary data from relevant literature, measuring the intensity of sunlight at selected locations, as well as computer simulations to predict the energy output of solar panels. The analysis is carried out by considering factors such as weather conditions, orientation and tilt angle of the solar panels, and energy conversion efficiency. Please note: The research results show that the potential for renewable energy from solar panels in the selected locations is very significant. With optimal sunlight intensity and proper panel angle adjustment, ecotourism can produce most of its energy needs from this renewable energy source. The use of solar panels also has a positive impact in reducing carbon footprints and long-term operational costs. and the integration of solar panels in ecotourism development planning is a strategic step that can increase sustainability and energy efficiency. Recommendations from this research include wider implementation of solar panel technology, increased education about the benefits of renewable energy, as well as supporting policies from the government to encourage the adoption of green energy in the tourism sector.

Abstract

There are several things that happen when customers use electricity with prepaid Kwh meters. One of the problems now is an error in the Kwh meter or commonly called Kwh tempering. This study uses an observation method by taking a sample of 2 houses that have tempering problems in their Kwh. The results of the study of the first house with 900 VA electricity power found a current leak of 0.3 A, and in the second house with 1300 VA electricity power found a grounding cable connected to the neutral cable which caused a limping load of 0.85 A.

Abstract

Solar energy is a renewable energy source that can be effectively utilized to generate electricity through photovoltaic cells. This research aims to plan an off-grid Solar Power Plant (PLTS) at the Sejahtera Islamic Boarding School Multipurpose Building. The system is designed as an alternative energy source to ensure the continuous operation of a 24-hour CCTV security system. The methodology included literature studies, field observations, and data collection to design a reliable power system. Implementing a PLTS is highly recommended due to its minimal emissions and eco-friendly nature. Based on the planning and analysis, implementing this off-grid PLTS to support the operational reliability of the CCTV system is highly feasible. The research location possesses adequate solar potential, with an average sunlight duration of approximately 4.5 hours per day. This capacity is sufficient to meet the 24-hour electrical energy needs of the CCTV and its supporting devices. System planning demonstrates that the daily load requirement of 432 Wh can be fulfilled using one 100 Wp solar panel module, two 12 V 33 Ah batteries, a 500 W inverter, and a 20 A Solar Charge Controller (SCC). Ultimately, this off-grid PLTS ensures an uninterrupted electricity supply during PLN network outages. It serves as an environmentally friendly, economical, and sustainable solution to enhance CCTV-based security systems in Islamic boarding schools and similar facilities.
