Abstract

Low grounding resistance is an important factor in ensuring the safety and reliability of electric power systems, especially on High Voltage Overhead Lines (SUTT). This study aims to analyze and improve the grounding resistance values on 150 kV SUTT towers on the Glang–Namorambe line using the three-point measurement method. Measurements were conducted to determine the actual condition of the grounding system and evaluate the effectiveness of the improvements made. Initial measurements showed that several towers had resistance values exceeding the maximum PLN standard limit of 10 ohms. To address this, improvements were made by installing additional electrodes, adding conductors, and using ground enhancement materials. After the improvements, remeasurements were conducted for each tower. The analysis results showed that the applied improvement method succeeded in reducing the grounding resistance value significantly, with an average reduction of 40–60%. The final resistance values of all towers were below the specified threshold, so that the grounding system can function properly in protecting equipment and personnel safety from overvoltage disturbances caused by lightning and ground faults.

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

The rapid growth of the Internet of Things (IoT) has enabled the integration of smart energy management systems into residential environments, allowing users to remotely control and monitor household electrical devices in real time. This paper presents the development of a cloud-connected smart home control system using the ESP32 microcontroller and a relay module as the switching interface for electrical appliances. The system is designed to optimize energy efficiency and power consumption through the implementation of wireless control via Wi-Fi and real-time data synchronization with a cloud server. The development of Internet of Things (IoT) technology provides a great opportunity in creating a smart and efficient home automation system. This study discusses the design and implementation of a household device control system using an ESP32 microcontroller integrated with a relay module as a controller for electrical loads such as lights and fans. The main objective of this study is to design a prototype of an IoT-based control system that can be operated via a Wi-Fi network and controlled using a smartphone application. The research method includes hardware design (ESP32, relay module, and electrical load), software design (user interface and connection to the Blynk platform), and system testing for response speed and communication stability. The test results show that the system can control devices with an average response time of 0.42 seconds, and a communication success rate of 98.7%. The results of this study prove that the use of ESP32 and relay modules as an IoT-based control system can be applied effectively for household automation, and become the basis for the development of smart homes in the future.
