Ultrafiltration of passion fruit juice using variation thickness of ceramic membrane has been done. The result shows that aquades flux value in 25 minutes for membrane 1.5; 2.0; 2.5; 3.0; and 3.5 mm is 17.0135; 19.1947; 10.9061; 10.9061 and 4.3624 L/h m2. Whereas passion fruit juice in same time for membrane 1.5; 2.0; 2.5 mm is 8.2886; 5.6712 and 4.3624 L/h m2. For membrane 3.0 and 3.5 mm it has not been done because flux value are too small that indicate fouling. Physical and chemical

... s parameter in ultrafiltration of passion fruit juice obtained for turbidity and color very different between passion fruit juice before and after ultrafiltration, whereas reducing sugar and vitamin C are not significant different between passion fruit juice before and after ultrafiltration. Determination rejection coefficient value of membrane for turbidity, color relatively significant whereas for reducing sugar and vitamin C are relatively not significant.
