Abstract

The aim of this research was to determine the effect of giving Bokashi Tofu Dregs and Palm Oil Solid Waste (Solid) on jackfruit pre-nursery both in interaction and primarily. This research used a factorial completely randomized design (CRD) consisting of 2 factors. The first factor is Bokashi Tofu Dregs 0, 225, 300, 375 g/polybag and Palm Oil Solid Waste (Solid) 0, 80, 160, 240 g/polybag. Thus, 16 treatment combinations were obtained with three repetitions, so there were 48 experimental units. In each treatment there were 4 plants with 2 plants as sample plants. The parameters observed were plant height, number of leaves, stem diameter, leaf area, total plant wet weight, total plant dry weight, root wet weight and root dry weight. Data for each treatment were analyzed statistically and continued with a real difference test (BNJ) at the 5% level. The research results showed that the interaction between Bokashi Tofu Dregs and Solid Palm Oil Waste (Solid) had a significant effect on the observation parameters of plant height, number of leaves, leaf area, total plant wet weight and total plant dry weight. The best treatment is giving bokashi tofu dregs 375 g/polybag and palm oil solid waste 240 g/polybag (B3L3). The main effect of tofu dregs bokashi had a real influence on all observation parameters with the best treatment being given 375 g of tofu dregs bokashi/polybag (B3). The main influence of solid palm oil waste (solid) had a significant effect on all observation parameters with the best treatment being solid palm oil waste (solid) 240 g/polybag (L3).
