Abstract

This study aims to determine the effect of coconut water and gibberellins on the germination of rattan seeds. The research design used was a completely randomized design with a factorial pattern consisting of 2 factors with 5 repetitions. The first factor (A) is coconut water consisting of control without coconut water 0% (A0), coconut water 25% (A1), coconut water 50% (A2), coconut water 75% (A3), and coconut water 100%(A4 ). The second factor is the concentration of gibberellins (GA3) consisting of control without gibberellins 0 ppm, 30 ppm (B1), 60 ppm (B2), and 90 ppm (B3). The results showed that coconut water and gibberellins had a significant effect on the percentage of germination, seedling height, number of roots, root length, and wet weight of rattan plants. A treatment combination of 75% coconut water and 90 ppm GA3 was the best treatment for the parameters of germination percentage (92,94%), seedling height (8,05cm), number of roots (4,06), root length (10,75cm), and wet weight rattan (5,04 grams).

Abstract

The aim of this research was to determine the effect of giving chicken manure liquid organic fertilizer (LOF) on the vegetative growth of kratom plants and to find out the best concentration of chicken manure LOF that can increase plant growth kratom. This study used a completely randomized design which consisted of 7 treatment levels of chicken manure concentration of LOF, namely: control(A1), 50ml/L(A2), 100ml/L(A3), 150ml/L(A4), 200ml/L(A5), 250ml/L(A6), 300ml/L (A7). The results showed that the application of LOF chicken manure had a significant effect on the number of leaves, root dry weight, and shoot dry weight, but had no significant effect on plant height, leaf area, weight root wetness, shoot wet weight and chlorophyll content. The LOF treatment of chicken manure concentration of 150ml/L was the treatment that gave the best results on kratom plant growth for the average number of leaves (16.0 strands), root dry weight (3.94 grams), and shoot dry weight (5.48 grams).

Abstract

This research aimed to determine the addition of chicken manure trichocompost to increase the growth of pakcoy. This study used a completely randomized design with 5 levels of trichocompost fertilizer treatment, namely without trichocompost fertilizer (Control), 40 grams, 60 grams, 80 grams, and 100 grams. The results showed that the application of chicken manure trichocompost 100 grams was the treatment that gave the best results on the growth of pakcoy plants for the parameters of the average number of leaves (15.6 leaves), leaf area (41.04 cm2), crown wet weight (52.64 grams) and roots (2, 52 grams), dry weight of shoots (2.00 grams) and roots (0.25 grams), and leaf coarse fiber content (1.51%).
