ANALISIS FAKTOR RANTAI PASOK (SUPPLY CHAIN) MATERIAL SEBAGAI PENYEBAB KETERLAMBATAN PEMBANGUNAN GEDUNG = MATERIAL SUPPLY CHAIN RISK ANALYSIS FOR CONSTRUCTION IMPLEMENTATION

The construction sector plays a crucial role in infrastructure development and economic growth, where project success is determined by the quality of results, timeliness, and cost efficiency. The performance of the material supply chain is crucial because it involves complex processes from procurement to installation on the ground. Disruptions such as late deliveries, improper storage, and lack of coordination can lead to delays and cost overruns. A preliminary survey on the Justice Tower construction project at the Faculty of Law, Hasanuddin University, showed that delays because poor material storage. This study aims to analyze material supply chain risks and formulate solutions to prevent a decline in project performance. The study was conducted over six months using questionnaires, field observations, and documentation, with 35 respondents determined using the Slovin formula. Four variables were studied: supply, control, process, and demand. Analysis using RII and Probability Impact showed that the control factor was the most dominant, especially sub-factor C3, which is negligent material storage that causes damage, with an extreme risk category (RII 0.71; SI 16). Mitigation recommendations include damage assessment and documentation, material replacement, adequate storage, routine record-keeping, and improved communication between relevant parties. These steps are expected to improve supply chain performance and support timely project completion.
