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.

Abstract

Nowadays, electrical energy is an essential necessity in modern life. To meet the demand for electricity in various sectors, such as households, industry, business, and tourism, it is necessary to improve the quality, quantity, and reliability of electricity supply. Efforts to improve electrical energy services require cooperation between PLN as a provider and the community as a user. One form of community contribution in supporting service improvement is by moving electricity use from peak load time (WBP) between 18.00-22.00 to outside peak load time (LWBP) at 22.00-18.00. This study aims to analyze the effect of load shifting on consumer load factors and its impact on electricity bill components, including energy costs, street lighting taxes, and stamp duty costs, on medium-voltage customers. Data was collected through a survey at PT PLN (Persero) Bali Medium Voltage Service Area Distribution (APTM) and interviews with 73 customers as a sample. The results of the study show that the shift in load from WBP to LWBP significantly increases PLN's efficiency by distributing electricity more evenly to consumers. This method also improves the load factor, which contributes to cost savings in generation and distribution of electricity as the plant does not need to operate at maximum capacity. One effective way to reduce the load on electricity is to move consumption from night to morning or day.
