Sub-district of Sukasada is one of arabica coffee centre in Buleleng District of Bali. This coffee areas has been developed for organic coffee with the certification from Geographical Indication (GI), Control Union (CU) and Rain Forest certifications. Area which has been covered around 400 Ha under 7 Farmers Group to support the sustainability of organic coffee development. It is important to implement onfarm research for developing local specific eco- friendly technology. Reseach was implemented in 2018 at Wanagiri village, Sukasada subdistrict of Buleleng. The purpose of research was to increase the yield of coffee through producing and applying the liquid fertilizer from liquid waste of wet processing. Research design used was block design, with four treatments and 4 replications in each treatment have 20 plants as samples. Coffee variety of Kopyol was used for treatment with age already 5 years after planting. Trial components are : P0 = farmers way (5 kg/tree), P1 = 200 ml bio urine/tree + 5 kg compost/tree, P2 = 100 ml bio urine/tree + 100 mlt liquid organic fertilizer from liquid waste of wet coffee processing + 5kg compost/tree, P3 = 200 ml liquid organic fertilizer from liquid waste of wet coffee processing + 5 kg compost/tree, P4 = 200 ml wet organic fertilizer + 5 kg compost/tree. Variables measured was number of produvtive branch, number dompol per productive branch, number of seed per dompol, and production per hectare through taxation methode. From the above treatments, P3 provide the highest yield 0.87 kg OSE coffee/tree/year, followed by P2 0.82 kg, P1 0.59 kg, P4 0.56 kg and the lowest was from P0 0.51 kg OSE coffee per tree per year.
