Abstract
The implementation of electronic procurement systems has become increasingly important in improving efficiency, transparency, and accountability within government procurement processes, particularly in construction project procurement. Despite the growing adoption of e-catalog systems in public procurement, various operational, technological, and organizational constraints continue to affect their effectiveness. This study aims to identify the determinants and key indicators of constraints affecting e-catalog utilization in livable housing project procurement in Aceh Province, Indonesia. A quantitative research approach was employed, using questionnaire surveys distributed to government stakeholders involved in procurement activities, including Commitment-Making Officials (PPK), Technical Activity Implementation Officials (PPTK), and Assistant PPTK personnel. Using a saturated sampling technique, 40 valid responses were obtained from a total population of 44 respondents. Data were analyzed using descriptive statistics, reliability testing, and Relative Importance Index (RII) analysis to determine dominant constraint factors and indicators. The findings reveal that Human Resource Competency and Culture emerged as the most dominant constraint factor (RII = 0.729), followed by Operational System Readiness (RII = 0.711), Infrastructure Capacity (RII = 0.708), Procurement Process (RII = 0.682), and Supplier Ecosystem Constraints (RII = 0.681). At the indicator level, slow data access within the e-catalog system recorded the highest RII (0.835), indicating that technological accessibility remains the primary operational challenge. The study concludes that improving e-catalog effectiveness requires integrated interventions addressing technological readiness, human resource capability, operational processes, and supplier ecosystem development to support more efficient and sustainable digital procurement systems.
