Abstract

Indonesia is one of the largest coffee producing and exporting countries in the world. Most of the production is robusta variety. Coffee is the fourth largest foreign exchange earner for Indonesia after palm oil, rubber and cocoa and is a source of income for the community. Coffee can be developed in a generative (seed) and vegetative way, including using cuttings. Efforts to accelerate the formation of roots in cuttings can be done by using natural growth regulators, one of which is shallots which contain auxins. The purpose of this study was to examine the effect of shallot extract on the growth of robusta coffee cuttings (Coffea canephora). This research was conducted from December 2019 to February 2020 at Campus II, Batanghari University (Pijoan). The design used in this study was a completely randomized design (CRD) with one treatment factor, namely shallot extract including; .k0 (without giving onion extract), k1 (250 g of shallots in 1 liter of distilled water), k2 (500 g of shallots in 1 liter of distilled water), k3 (750 g of shallots in 1 liter of distilled water), and k4 (1000 g of shallots in 1 liter of distilled water). Each stage of the experiment was repeated 3 times, so that there were 15 experimental plots, for each experiment there were 10 cuttings with a total of 150 cuttings. The observed data were analyzed using analysis of variance followed by the DNMRT test at α 5%.

Abstract

Oil palm empty fruit bunches are a source of organic matter rich in nutrients N, P, K, and Mg. TKKS has the properties of helping nutrient solubility, improving soil structure, water absorption capacity, and carbon source, and providing energy for soil microorganisms needed for plant growth. This study aimed to determine the effect of composting empty palm oil bunches on the growth of cocoa seedlings. The materials used are F1 cocoa seeds (high-quality seeds) aged three months, polybags measuring 15 x 30 cm, TKKS fertilizer, NPK 15-15-15 fertilizer, and ultisol. The equipment used is a set of tools for seeding cocoa, scales, tape measure, paranet, calipers, and an electric oven. The research design was a one-factor complete randomized design. TKKS fertilizer treatment design (k) with four dose levels in 3 kg of planting medium, namely: k0 = control, k1 = 100 g, k2 = 200 g, k3 = 300 g. Parameters observed were plant height, stem diameter, shoot dry weight, root dry weight, media moisture content, soil physical and chemical analysis. The data obtained were analyzed statistically using analysis of variance. If the variance analysis results have a significant effect, continue using the DNMRT test at the level of α = 5%. TKKS fertilizer treatment at a dose of 300 g produced cocoa seedlings aged six months with a height of 54.33 cm, stem diameter of 10.02 mm, dry crown weight of 33.13 g, root dry weight of 15.56 g, and media moisture content without watering for five day of 6.71%.

Abstract

Robusta coffee plants are cross-pollinated, so the genetic characteristics of the new plant are not the same as the parent if propagation is carried out generatively. One way to overcome this problem is through vegetative propagation. The research aims to determine the effectiveness of organic and inorganic growth regulators to support the growth of robusta coffee cuttings. This research was conducted at the Experimental Station, Campus II, Batanghari University in Pijoan, Jambi from April to August 2022. The research used a completely randomized environmental design. The treatment design is 5 levels of organic and inorganic growth regulators, namely (p0): control, (p1): 50% onion shallot extract, (p2): natrium nitrophenol 0.60 mLL-1, (p3): 75% onion shallot extract, (p4): natrium nitrophenol 0.90 mLL-1. The parameters observed were live cuttings, rooted cuttings, sprouted cuttings, rooted and sprouted cuttings, number of roots, dry weight of roots, air temperature and air humidity. Research data was processed using anova. Further data processing takes the form of orthogonal contrast to compare organic and inorganic growth regulators. A onion shallot extract concentration of 75% is better than a concentration of 50% and a natrium nitrophenol concentration of 0.9 mLL-1 is better than a concentration of 0.6 mLL-1. Treatment with 75% onion shallot extract resulted in 100% growing cuttings, 100% sprouting cuttings, 60.22% rooted cuttings, and 60.22% sprouting and rooting cuttings. Natrium nitrophenol treatment with a concentration of 0.9 mLL-1 resulted in 100% growing cuttings, 100% sprouting cuttings, 65.55% rooted cuttings, and 65.55% sprouting and rooting cuttings. Organic growth regulators from onion shallot extract and inorganic substances from natrium nitrophenol have the same effect in stimulating the growth of robusta coffee cuttings.
