Abstract

ABSTRACT This research examines the potential of oil palm leaves as raw material for compost, carried out in Bandar Pasir Mandoge Village, North Sumatra, from March to May 2023, using a Completely Randomized Design (CRD) with two main factors: compost material and type of decomposer. The compost material consists of tankos, leaves, and a mixture of tankos+leaves, while the decomposer consists of decomposers D1, D2, and D3. The parameters measured include C/N ratio, weight loss, compost color, compost odor, compost pH value, compost temperature, compost humidity, and compost friability. The research results showed significant variations in C/N ratio values ​​for organic materials, with values ​​ranging from 12 to 38. Compost material from leaves with D1 decomposer achieved the lowest C/N ratio value, while tankos compost with D1 decomposer had the highest value. Decomposer D2 is more effective in speeding up the decomposition process compared to D1 and D3. The fastest compost shrinkage occurred in the treatment with D3 decomposer, while the longest shrinkage occurred in the treatment with D1 decomposer. This research supports the principles of sustainable agriculture by utilizing high fiber organic waste and reducing environmental pollution. Tankos organic material decomposes the fastest, and the D2 decomposer is more effective than other decomposers. There is a real interaction between organic materials and decomposers on compost quality. Keywords: Tankos, leaves, compost, decomposer

Abstract

Abstract - This study was to determine the effect of light quality and frequency of paclobutrazol application on the growth and yield of chrysanthemum plants. The research was conducted from February to April 2023 using factorial design and arranged in Split Plot Design consisting of Main Plot and Sub Plot. Main Plot was the effect of light quality using three different light colors, namely white light, red light, and blue light. Sub Plot was the frequency of paclobutrazol application which consists of 4 kinds, namely 0 times, 1 time, 2 times, and 3 times. Data analysis used in this study was analysis of variance with 5% confidence level. The results showed an interaction between the quality of light and the frequency of paclobutrazol application on the parameters of stem diameter and leaf area. Light quality had a good effect on the parameters of plant height, flower color, flower quality, number of flowers, number of leaves and flower diameter. The frequency of paclobutrazol application had a good effect on the parameters of plant height, flower color, flower quality, number of flowers, number of leaves and flower diameter. The best plant height was 106.39 cm, the highest number of leaves was 15.5, the best leaf area was 89.42 cm2, the best stem diameter was 0.41 inches, the best flower color with a score of 2.5, the best flower quality with a score of 2.8, the largest flower diameter was 7.93 cm, and the largest number of flowers was 5 flowers.
