PENGARUH BERBAGAI DOSIS BOKASHI AMPAS TAHU TERHADAP PERTUMBUHAN SEMAI NYATOH (Palaquium Obtusifolium Burck) DI LAPANGAN

Abstract
Nyatoh (Palaquium obtusifolium Burck) is a plant that is spread throughout Indonesia. This plant has quite high ecological and economic value. This research aims to determine the effect of various doses of bokashi tofu dregs on the growth of nyatoh (Palaquium obtusifolium Burck) seedlings in the field. This research was carried out for three months from September to December 2023, located in Uwemanje Village, District. Kinovaro, Kab. Sigi, Central Sulawesi. This research used a Completely Randomized Design (CRD) method with five treatment doses of bokashi tofu dregs, namely: A0 = Without Bokashi Tofu Dregs (control), A1 = 250 g / Planting hole, A2 = 500 g / Planting hole, A3 = 750 g / Planting hole, A4= 1 kg / Planting hole. Each treatment was repeated 7 times, so that the total seedling units used were 35 seedling units. Observation parameters are seedling height, diameter, number of leaves. Test variance analysis (F) is used if the treatment has a significant effect on the observed parameters, then it is continued with a further Honest Significant Difference (BNJ) test at a real level of 5%. The results showed that giving a dose of bokashi tofu dregs to Nyatoh seedlings had a significant effect on the increase in height, diameter and number of leaves of Nyatoh seedlings. Based on the results of further tests (BNJ) 5%, it shows that the A4 treatment (1 kg / planting hole) has the best effect on the growth of nyatoh seedlings compared to other treatments with an average increase in height of 24.2 cm, an increase in the number of leaves with an average of 3, 71 strands, with an average increase in diameter of 2.41 mm.
