T This study aims to analyze the dominant risk factors arising from inaccuracies in the owner’s cost estimate (harga perkiraan sendiri/hps) in the procurement of goods and services in property projects in jakarta during the 2020–2023 period, as well as to formulate effective mitigation strategies to minimize their impact. the research employed a combination of the analytical hierarchy process (ahp) and simple additive weighting (saw) methods to objectively identify, prioritize, and evaluate risk weights. a total of 54 procurement practitioners participated as respondents, providing assessments across three main risk categories: cost, time, and quality. the results of the ahp and saw analyses reveal that inaccuracies in the hps significantly affect budget efficiency, procurement delays, and the quality of goods or services received. cost-related risks are primarily driven by document instability and unexpected expenses (overbudget), while time-related risks are influenced by delays in document evaluation, repeated hps revisions, and prolonged negotiations. quality risks largely stem from the use of low-quality materials, failure to meet technical specifications, and inadequate supplier capabilities. to address these issues, the study proposes several mitigation strategies, including updating hps based on current market data, conducting regular price surveys, enhancing procurement team competencies through technical training, adopting digital technologies and e-procurement systems, and implementing stricter quality control through transparent and performance-based supplier selection. this research contributes theoretically to the literature on procurement risk management and offers practical guidance for property companies in enhancing the effectiveness and efficiency of their procurement processes.
