<![CDATA[The development of buying and selling transactions through social media has transformed consumer behavior, particularly in the purchase of preloved goods through online communities. Peer-to-peer transactions have led to the emergence of consumer trust and perceived risk as factors that may influence purchasing decisions. This study aims to examine the influence of consumer trust and perceived risk on purchasing decisions for preloved goods in the Murah-Murahcommunity on Platform X. The study was conducted during the April–May 2026 period using a quantitative approach and a survey method. Data were collected by distributing questionnaires to 100 respondents who had previously purchased preloved goods in the Murah-Murah community on Platform X. The sampling technique employed was non-probability sampling using purposive sampling. The data were analyzed using validity and reliability tests, classical assumption tests, multiple linear regression analysis, t-test, F-test, and the coefficient of determination with the assistance of SPSS software. The results indicate that consumer trust has a positive and significant partial effect on purchasing decisions, with a significance value of 0.000 < 0.05. Perceived risk also has a positive and significant partial effect on purchasing decisions, with a significance value of 0.000 < 0.05. Simultaneously, consumer trust and perceived risk have a positive and significant effect on purchasing decisions for preloved goods in the Murah-Murah community on Platform X, with a significance value of 0.000 < 0.05.]]>
