ASSESSMENT BANGUNAN DERMAGA (STUDI KASUS PELABUHAN KHUSUS NAVIGASI KENDARI)

Abstract

Kendari Special Navigation Port is one of the important infrastructures in supporting the safety of navigation and operational ships in Southeast Sulawesi. As the age of the dock structure increases, and maybe almost reaching 30 years, the visual condition of the concrete structure indicates physical damage such as cracks, porous concrete and corrosion in the dock structure reinforcement. This study aims to determine the quality of the dock structure concrete using the Non-Destructive Test (NDT) method and conclude whether the concrete quality strength still meets the standards required for the current dock structure. This NDT method uses a Schmid Hammer Test tool according to the SNI ASTM C805:2012 standard to determine the concrete quality strength in a non-destructive manner. The testing was carried out on the structural elements of the floor slab, beams and pile caps of the dock, the average concrete quality strength results for the floor slab structure are 30 MPa or 306 kg/cm², for the beam structure the average concrete quality strength value is 22 MPa or 228 kg/cm² and for the pile cap structure of the dock the average concrete quality strength value is 26 MPa or 261 kg/cm². Fom these results, we can conclude that the concrete quality of the floor slabs is still in the medium to high quality category and meets the minimum standards for structures in marine environments. However, the compressive strength values ​​for the beam and pile cap structures do not meet the minimum standards for pier structural elements, requiring further technical evaluation and corrective action to ensure the safety of the pier structure.
