Abstract

Oil palm plants can be grown on flat, wavy, and hilly land with a land slope range of 0%-30%. The oil palm plantation area of PT ABC is 14.7 thousand Ha, with the landscape dominated by hilly topography. Conservation practice of the hilly regions in PT ABC is carried out by making contour roads and terraces. At PT ABC on five blocks in Division 1, block O, L, K, M, J was making a non-standard contour road. Therefore, these conditions cause decreases in production because the harvester has difficulty carrying fruit, and finally, the fruit is left behind. To overcome it, PT ABC opens the road (harvesting path) specifically for harvesting to resolve the problem. This research aims to determine the impact of harvesting path formation on oil palm production at PT ABC. The methodology of the study is by comparing data obtained from companies and analyzed descriptively in the field. The data collected are primary data and secondary data. The results showed that harvesting path formation influences oil palm production in PT ABC by increasing output by 21%-38% or increasing by an average of 1 ton/Ha/year.

Abstract

This study aims to determine the effect of dosage and frequency of liquid organic fertilizer made from Turileaves on the growth and yield of land spinach plants (Ipomoea reptans Poir). The study used a factorial randomized block design (RBD) consisting of 2 factors. The first factor is the dosage of turi leaf liquid organic fertilizer consisting of 4 levels, namely, Turi Leaf LOF 0 ml/l (P0), Turi Leaf LOF 1.5 ml/l (P1), Turi Leaf LOF 3 ml/l (P2), Turi Leaf LOF 4.5 ml/l (P3). The second factor is the frequency of application consisting of 3 levels, namely application of LOF once a week (F1), application of LOF twice a week (F2), and application of LOF three times a week (F3). The results showed that the application of a dosage of 4.5 ml/l liquid organic fertilizer 3 times a week application gave the best results for plant height (30.60 cm), Number of Leaves (14 leaves), Stem Diameter (8.36 mm), Root Length (16.76 cm), and Harvest Weight (11.86 gr).
