INFRASTRUCTURE DESIGN OF RESTRICTED SECURITY AREA FENCING TO ENHANCE AIRPORT SECURITY

Ahmad Ardi Zulkarnain, Achmad Muhyidin Arifai, Deni Priansyah
Abstract: This study aims to develop a technically compliant and economically feasible design for a Restricted Security Area (RSA) perimeter fence surrounding Substation 7, the Chiller facility, and the Ground Water Tank (GWT) at… Kertajati International Airport. These facilities constitute critical operational infrastructure supporting electricity distribution, terminal cooling systems, and water supply, including fire suppression reserves. Field observations identified the absence of a regulation-compliant perimeter protection system, exposing the utility cluster to unauthorized access and operational risk. The research employed a quantitative descriptive–analytical approach integrating field measurement, engineering design modeling, volume computation, and cost estimation based on the 2024 Majalengka Regional Standard Unit Price. Technical evaluation referred to national aviation security regulations and ICAO Annex 17 principles. A BRC (British Reinforced Concrete) fence system with a total height of 3.20 meters (2.40 m fence body and 0.80 m concertina wire) was proposed. The structural configuration includes reinforced concrete isolated footings, tie beams (sloof), and a bottom plinth beam to ensure lateral stability and anti-climb resistance. The total perimeter length of 313.74 meters ensures complete enclosure of the critical facilities. The estimated total project cost amounts to IDR 509,553,000.00, including VAT. The results demonstrate that the proposed design is structurally reliable, regulation-compliant, and economically justified within a risk mitigation framework. The study contributes a replicable engineering and financial planning model for strengthening airport critical infrastructure protection and enhancing long-term operational resilience.

Analysis of Metal Fiber Testing with Pondidaha Coarse Aggregate and Konawe Fine Aggregate Against Flexural Strength (Beams)

Haydir, Haydir, Eva Delpia, Villa, Sakti, Putra, Safitri Maladeni, Eva
Abstract: The territory of Indonesia is a high level of earthquake risk among several earthquake areas around the world. One way to reduce the occurrence of potential damage to building construction is to utilize waste and metal as… s added material from coarse and fine aggregate to the flexural strength of beams that have equivalent flexural strength. The equivalent flexural strength value tends to increase with the addition of metal fibers. This study aims to determine the effect of adding metal fibers to the flexural strength of the beam and the pattern of cracks and collapse mechanisms that occur in the beam when the object is tested. This research is a type of quantitative research with physical laboratory experimental methods. The data collection method used is a preliminary study, The selection of the type of aggregate and metal fiber and secondary data were then carried out laboratory tests for the gradation of fine aggregate and coarse aggregate. The data analysis technique is linear regression analysis in the Ms. program. Excell to determine the effect of metal fibers as additives on the flexural strength of the mixing of coarse and fine aggregates.
