When raising animals, cooperatives are a place for the welfare of dairy producers. Cooperatives run a number of programs to help their members get the most out of the resources generated by the animals they farm. The purpose of this study was to determine the degree of trust dairy farmers have in the cooperatives in which they participate. A sample of 101 dairy farmers from the Sleman Regency’s Pakem and Cangkringan Subdistricts served as the basis for this study. A questionnaire tool that has undergone validity and reliability testing is used to collect the data in the form of primary data. Dairy farmers’ confidence in cooperatives was measured using PCA (Principal Component Analysis), and the results showed that trust in close friends in cooperatives is the key factor that may reduce other factors and explain 89.174% of the variance that happens.
