Abstract

This study aims to analyze the potential for veer-off on Rapid Exit Taxiways (RET) based on the operational and geometric characteristics of the facility, taking into account traffic conditions during peak days and peak hours. The analysis was conducted by evaluating the relationship between aircraft maneuvering demand and the available geometric capacity and maneuvering capability through the Demand–Capacity Ratio (DCR) approach. The parameters used include the type and characteristics of aircraft, speed when entering the RET, turning radius, taxiway width, friction coefficient, and lateral acceleration. Furthermore, the DCR results are used to identify critical conditions that could lead to potential veer-off, referring to Galagedera et al.'s approach, which considers the relationship between RET geometric characteristics, aircraft speed, and lateral force capacity in maneuvering. The analysis results show that DCR > 1, so there is a potential for veering off the path in traffic at Minangkabau International Airport, projected for the year 2044.

Abstract

This study aims to analyze the use of local Madura materials as coarse aggregates, combining limestone from Lesong Village, Batumarmar District, and coral rock from Karang Village, Waru District, with the addition of type F superplasticizer additive to the compressive strength of concrete. The research was conducted experimentally in a laboratory with a planned concrete quality of fc' 25 Mpa with variations Superplasticizer dosage of y0%, 0.5%, 1.0%, and 1.5% of the cement weight, with concrete testing ages of 7, 14, and 28 days. The parameters tested included aggregate characteristics, slump test, concrete weight and volume weight, and concrete compressive strength. The results showed that the addition of 0.5% Superplasticizer type F was the most optimal dosage because it could improve workability and concrete compressive strength to meet the planned quality of 25 MPa. Conversely, the use of 1.0% and 1.5% doses caused a decrease in compressive strength due to segregation. Thus, the most effective combination to produce optimal compressive strength is the use of mountain coral and limestone with PWRPro green cement and 0.5% type F superplasticizer.
