The technology of hollow fiber photo catalytic membrane composite often used in pesticide treatment, including profenofos degradation. This study aims to determine the influence of dope composition variation on mechanical properties and performance of hollow fiber photo catalytic membrane composite of cellulose acetate (CA)-TiO2 for profenofos degradation. Hollow fiber photo catalytic membrane composite of CA-TiO2 prepared using phase inversion method. Dope composition variation (CA: acetone: formamide) used were 19.8%: 72%: 8%; 20.8%: 52%: 27%; 21.8%:51%: 27%; 22.8%: 50%: 27%; 24.8%: 45%: 30% (% w/w) and addition 0.2% TiO2 (% w/w).Characterization of CA-TiO2 hollow fiber photo catalytic membrane composite include: mechanical properties test, SEM, FTIR, performance test and application for profenofos degradation. The results of this study concluded that the optimal dope composition of CA-TiO2 hollow fiber photo catalytic membrane composite (CA: acetone: formamide) is 24.8%: 45%: 30% w/w. Mechanical characteristics of CA-TiO2 hollow fiber photo catalytic membrane composite includes 1,85 x 103 kN/m2 of stress, 1.71 of strain and 4,9 x 103 kN/m2 of Youngâs modulus. The performance test of CA-TiO2 hollow fiber photo catalytic membrane composite for profenofos degradation resulted in 61.72 L/m2.h. of flux, 43.49% of rejection coefficient, and 43.50% of total efficiency degradation.
