The study aimed to find out the best combination  the use of inorganic fertilizers (PA) with liquid fertilizers (PC) of tofu factory wastewater in cucumber cultivation.This study used a onefactor Completely Randomized Design (CRD) method consisting of six treatments(P0=Control);(P1=PC (75% of fertilization dose) + PA (25% of fertilization dose); (P2= PC (50% of fertilization dose) + PA (50% of fertilization dose); (P3=PC (25% of fertilization dose) + PA (75% of the fertilization dose); (P4=PC (100% of the fertilization dose); (P5= PA (100% of the fertilization dose).Fertilizers dose same to Urea 160 kg ha^-1, TSP 72 kg ha^-1 dan KCl 120 kg ha^-1. The conclusion of this study on the parameters of plant dry weight treatment P2 (75% PA+25% PC) and treatment P3 (50% PA+50% PC) is a combination of fertilizers that can match 100% inorganic fertilizers. The parameter of fruit weight plant the P3 treatment (50% PA+50% PC) is a combination of fertilizer application that can match 100% inorganic fertilizer.
