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

Cultured plants will adapt to new environmental conditions at the acclimatization stage. Changes that occur can observed through changes in morphological and anatomical structures.  The increase in the number of cells and the size of plant organs illustrates the process of changing the anatomical structure of plants. It is necessary to optimize the concentration of biostimulant given and see its effect on plant growth and anatomical structure, to explain the mechanism of action of biostimulants. The research aimed to determine the concentration of biostimulant cengkodok leaf extract on black orchid plants. The study used a completely randomized design consisting of 8 treatment levels of cengkodok leaf extract biostimulant concentration (0, 10, 20, 30, 40, 50, 60 and 70 mg/L).  The results showed that the concentration of cengkodok leaf extract 20 mg/L was the best concentration for the parameters of the number of leaves and the number of roots of black orchid planlets, respectively 2.5 leaves and 7.5 roots. The application of cengkodok leaf extract affects the anatomical structure characteristics of black orchids, including an increase in the thickness of leaf mesophyll tissue, stem cortex tissue, and roots.
