Abstract

The performance of passenger terminal services at Banyuwangi Airport is a critical determinant of the user experience in air transportation services, directly impacting passenger satisfaction and the airport's reputation. This research aims to evaluate the quality of services provided, identify key factors influencing service performance, and propose actionable recommendations for improvement. Using the Analytical Hierarchy Process (AHP) method, the study reveals that waiting room facilities, information services, and check-in process efficiency are the most significant elements requiring attention. Additionally, while passengers express high satisfaction with basic facilities such as hygiene and toilets, areas such as the circulation space and baggage services exhibit shortcomings that hinder operational efficiency and user comfort. To address these issues, several recommendations are proposed, including redesigning the circulation area to enhance passenger flow, optimizing baggage handling processes to improve speed and reliability, and introducing additional amenities such as more seating areas, improved signage, and dedicated zones for special needs passengers. These findings offer a strategic framework for Banyuwangi Airport managers to prioritize and implement targeted improvements, ultimately enhancing the overall passenger experience and supporting the airport's role as a gateway to East Java's tourist destinations.

Abstract

Housing construction is a recurring and sustainable job. So if the scheduling does not take into account the character of this work then the repetitive work unit will experience a delay (lag). So that it will result in the duration of the project. To overcome this, an uninterrupted scheduling method is needed from one unit to the next. The scheduling method that matches this type of repetitive work is the Line of Balance (LoB) because each activity / activity is described in a straight line and the speed of work can be changed according to needs. This is to avoid the occurrence of crashes / conflicts between activities. This method can also minimize the delay time as mentioned above. But this method cannot show dependency between critical activities and the other activities. For this reason, another method is needed in order to fill this gap. The suitable method is CPM through Microsoft Project. This combination of methods besides managing the time of project implementation also regulates human resources, namely by maximizing the allocation of human resources. Because in this multi-unit project the quantity of work is the main thing. From some analysis calculations, the results obtained that the addition of buffers with productivity speed smoothing, and the acceleration of the duration of the activity more effective to accelerate the implementation time of the project with a duration of 154 days.

Abstract

Architectural work in a construction project, generally is a non-structural work. However, the implementation can require a long time and a large cost weight. The implementation of finishing work in multi-purpose building construction project of Gresik Regency that was already running and had problems, that is a lot of workers but lack of work progress, so an increase of the cost from budget planned. Therefore it needs to doing research that for get the actual time of project implementation and get Estimate at Completion (EAC). The results is that the actual time of project implementation is not suitable with time of project planning. The project has been to late so there is a decrease in project performance. In the 1st week of project implementation on time, in the 2nd week until the 15th week the project has been to late (schedule overrun). So based on the time of implementation, the project has decreased performance. The total estimated cost can be seen from the Estimate at Completion (EAC) calculation, which is Rp.274,424,152.89.

Abstract

Road infrastructure plays a crucial role in supporting economic growth, particularly in agrarian and resource-rich regions. This research aims to conduct a comparative analysis of rigid and flexible pavement types in terms of cost efficiency and construction duration on the Sambeng–Kedewan road segment in Bojonegoro Regency. Utilizing the MDPJ 2017 method for flexible pavement design and Pd T-14-2003 for rigid pavement, this research employs a quantitative descriptive-comparative approach to analyze structural thickness, estimated construction costs, and implementation timelines for both 20- and 40-year design life spans. Primary data were collected through field surveys, including Dynamic Cone Penetrometer (DCP) tests for subgrade CBR values, while secondary data were sourced from government agencies and technical literature. Traffic load analysis was performed using ESA5 (Equivalent Standard Axle 5-ton) and JSKN (Number of Commercial Vehicle Axles) parameters, and cost efficiency was evaluated through RAB (Cost Budget Plan) and life cycle cost analysis (LCCA). Findings from various case studies and technical assessments indicate that although rigid pavement involves higher initial investment, it offers greater longevity and lower maintenance expenses in the long term. This research provides crucial insights for local governments in determining the most efficient pavement type under limited budgets and strict construction timeframes. The results are expected to serve as a reference for future infrastructure planning in similar rural and agricultural regions.
