The purpose of this study was to determine whether the pineapple fruit extract can inhibit the process of browning on the potato tubers. This study used Completely Randomized Design (RAL) with 5 levels of pineapple fruit concentration of 0% v/v, 25% v/v. 50% v/v, 75% v/v, and 100% v/v and consist of 5 replications. Qualitative Parameters in this study was the colo surface of potato tubers while quantitative parameters were browning index, total soluble carbohydrate content, and dehydrogenase enzyme activity homogeneity of variance, analysis of variance, and Tukey test were conducted at 5% significant level. Correlations between dependent and independent variables were determined by linear regression. The result showed that the color surface of potato tuber treated with the concentration of pineapple extract 100% v/v was less brown than control and other concentrations. Index browning of potato tuber treated with concentration 75% v/v and 100% v/v was significantly decreased. Concentration of pineapple extract was negative linearly correlated to browning index of potato tubers. The concentration of pineapple extract 100% v/v increased significantly total soluble carbohydrate of potato tubers. The concentration of pineapple extract was positive linearly correlated to total soluble carbohydrate. The activity of dehydrogenase enzyme of potato tuber treated with concentration 100% v/v was significantly increased. The concentration of pineapple extract was quadratic correlated to the activity of dehydrogenase enzyme
