Abstract

This study aims to quantitatively compare the cost and time efficiency between conventional concrete and precast concrete construction methods in the construction of the UIN Tulungagung Laboratory Building. The main focus of this study is to identify the most optimal method in the context of project implementation efficiency for medium-rise buildings in non-metropolitan areas. Scientifically, this study contributes to enriching the literature on the selection of construction methods based on location and project characteristics. Practically, the results of this study are expected to serve as a strategic reference for contractors, project planners, and other stakeholders in determining efficient construction methods that are appropriate for resource constraints, including budget, time, and equipment availability.

Abstract

This study analyzes the feasibility of the construction of regular petrol stations in Sepaku District, North Penajam Paser Regency, East Kalimantan. The need for development arises due to the increase in the number of vehicles that is not proportional to the availability of fuel infrastructure. A quantitative approach is used through fuel demand analysis, RAB preparation, and economic evaluation with NPV, BCR, and Payback Period. The results show that Semoi Dua Village is strategic because it is on the path to IKN with high population growth. Fuel needs are estimated at ±311,000 liters per week. The project is economically feasible with a positive NPV of IDR 15 billion, a BCR of 1.3, and a payback period of four years. Petrol stations are considered prospective operationally and economically.
