Abstract

Electricity Demand for electrical energy in the food industry, including restaurants, continues to increase alongside the use of high-powered production equipment. This study aims to develop an Internet of Things (IoT)-based electrical load monitoring and control system using App Inventor at the Bakmi GM Denpasar production unit. The system consists of two components: a server (App Inventor) and a client (a microcontroller device based on a current sensor). Methods used include hardware design for power consumption data acquisition and development of a user interface for real-time monitoring and control. Test results show that the system can detect and manage electrical loads with 96.8% accuracy and reduce energy consumption by 18.5%, compared to before the system was implemented. These results demonstrate that integrating IoT technology into industrial electricity systems can significantly improve energy efficiency, reduce energy waste, and support environmental sustainability.

Abstract

The growth of aviation activities at I Gusti Ngurah Rai International Airport, Bali, has led to the rapid development of surrounding areas, potentially obstructing protected airspace. Obstacles on the approach surface of Runway 27 have become a critical concern, particularly for precision approach Category II (CAT II) operations, which require obstacle-free approach areas. This study aims to analyze obstacles within the approach area of Runway 27 and develop effective control strategies. Using a descriptive qualitative approach, data was collected through field observations, interviews, and documentation studies. The analysis follows the Obstacle Limitation Surfaces (OLS) standards according to ICAO and national regulations. The findings reveal obstacles such as mangrove vegetation, antennas, and ship activities in the Benoa Harbor area, which are located within the approach surface and could potentially impact the OLS limits. While these obstacles generally comply with existing regulations, their proximity to the threshold may reduce the safety margin of flight operations and limit CAT II implementation on Runway 27. This study proposes technical, operational, regulatory, and preventive strategies to improve obstacle control, enhancing aviation safety and ensuring the readiness for CAT II operations at the airport.
