This research was conducted with the aim of optimizing the assignment of working hours in the Procurement Division of PT. Pelindo Multi Terminal through the application of the Hungarian method. The fundamental problem faced is the imbalance between the number of permanent workers and the high workload that must be completed, thus creating a risk of inefficiency in the operational process. To address this problem, a quantitative approach was used with linear programming modeling techniques designed to produce a more systematic and measurable assignment allocation. Through the analysis conducted, an optimal solution was obtained regarding the distribution of working hours, where the total working time can be reduced to 10,120 minutes per month, lower than the previously set maximum limit of 10,560 minutes per month. These results indicate that the application of the Hungarian method is not only able to reduce excessive workloads on some employees, but also ensures a more proportional distribution of assignments among all available workers. In addition, this method can increase operational effectiveness because each worker receives a load according to their capacity, so that the risk of fatigue or decreased performance can be minimized. The findings of this study confirm that the Hungarian method is an alternative work scheduling strategy that is efficient to be applied in industrial environments with high task complexity. Proper implementation can also support the achievement of overall company productivity, improve the quality of human resource management, and strengthen the company's competitiveness in facing future operational challenges.

The Terminal Loading Area (TLA) API at PT Pertamina Hulu Mahakam functions as a facility for processing oily water before being discharged into the environment. One of the main issues faced is the accumulation of thick floc (oil clumps) due to high emulsions in crude oil, along with the malfunctioning water spray valve on line 1, causing operators to resort to manual spraying using hydrant water. This increases the risk of exposure to hazardous chemicals such as Benzene, Toluene, and Xylene (BTX), which poses a health threat to workers. Therefore, improvements to the water spray system are needed to reduce BTX exposure and enhance the effectiveness of oil-water separation. This study aims to analyze the effectiveness of proposed improvements to the water spray system to reduce BTX exposure and improve the efficiency of oil-water separation. The methodology used includes literature review, field study, and technical testing. Proposed solutions include replacing or repairing the damaged water spray valve, adding piping networks to compartment 2 to distribute water more evenly, and using treated water (produced water) to optimize the system and reduce reliance on hydrant water. The results of the study indicate that replacing or repairing the water spray valve, adding piping networks, and using produced water effectively reduce BTX exposure while maintaining oil recovery effectiveness. The trials also showed that using the Oil Pump (P-3230 & P-3235) provides optimal pressure (8–9 barg) for water spray, compared to the less effective Water Pump (P-3200 & P-3205). Implementing these solutions is expected to reduce BTX exposure for workers, improve oil-water separation efficiency, and contribute to a safer and more efficient working environment.

This study aims to analyze passengers' understanding of prohibited items at Terminal 2 of Juanda International Airport and evaluate the effectiveness of information delivery strategies implemented to support aviation safety and security. The research uses a descriptive qualitative method with data collection techniques such as observation, interviews, and documentation. The findings show that most passengers, particularly elderly individuals, still do not have a clear understanding of the difference between items allowed in the cabin and those that must be placed in checked baggage. Information regarding prohibited items is only discovered when passengers reach the security check area (PSCP), which is considered too late, causing panic and discomfort among passengers. The main factor contributing to the low level of understanding is the unstrategic delivery of information and the lack of engaging communication media. Although information about prohibited items is available through posters and announcements, these methods do not effectively attract passengers' attention. Passengers often overlook the information placed in less visible or strategic locations. This indicates that the current information media have not been effective in providing significant impact on passengers' understanding. This study recommends several steps to improve passenger understanding. The placement of more effective information media, such as eye-catching educational banners and 3D video displays at the departure entrance area, is expected to attract more attention from passengers. Additionally, the use of digital platforms, such as airport apps or social media, could be an effective way to deliver information to passengers before they arrive at the airport. With these strategies, passengers can better prepare and avoid potential mistakes during security checks, thus supporting the smoothness and safety of their flights.  

This study explores the strategic use of garbarata as an advertising medium at Minangkabau International Airport, Padang. The garbarata, which is a connecting bridge between the terminal and the aircraft, has great potential as an exclusive advertising space and has high exposure to passengers. However, this potential has not been optimally maximized. This study uses a qualitative approach with a case study method. Data collection was conducted through in-depth interviews with airport management, direct observation of the garbarata conditions, and analysis of documentation related to advertising policies and non-aeronautical asset management. The results of the study indicate that there are several main obstacles in the use of garbarata as a promotional medium. These obstacles include minimal promotional activities to potential advertisers, unclear pricing systems for advertising space rentals, lack of collaboration with advertising agencies, and limitations in the provision of design services and visual creativity. This has led to low interest of companies in utilizing this media as part of their marketing strategy. To overcome these problems, this study proposes several development strategies, including: increasing active and planned promotional activities, setting flexible and competitive rental prices, strategic collaboration with professional advertising agencies, and providing creative design services to support the effectiveness of advertising messages. This strategy is expected to attract more companies to advertise on the aerobridge, thereby increasing the airport's non-aeronautical revenue. With proper optimization, the aerobridge will not only serve as a functional passenger facility but can also transform into a strategic asset supporting the airport's sustainable commercial development and creating added value for both the operator and its business partners.
