Abstract

Robusta coffee (Coffea canephora L.) is one of the mainstay commodities of plantations in Indonesia. Robusta coffee takes a long time to germinate because Robusta coffee has a hard seed coat so that it is difficult for water and oxygen to penetrate the seed coat which causes the germination process to be hampered. For this reason, it is necessary to speed up germination by stripping the hard seed coat and soaking it with gibberellins. The aim of this study was to obtain the proper concentration of gibberellins and soaking time on the germination of robusta coffee seeds with the husks removed. This research was conducted at the Biology Laboratory, Padang State University in November – January 2022. This study used a completely randomized design (CRD) with two treatment factors. The first factor is the concentration of gibberellins with 3 levels, namely 0, 10, and 20 ppm, the second factor is soaking time with 3 levels, namely 12, 18 and 24 hours. The results showed that the concentration of gibberellins had a significant effect on the parameters of germination height, root length, dry weight, percentage of germination in the early stages of radicle germination and seedling. the duration of immersion and the interaction of the two did not significantly affect the germination rate, vigor index, percentage of germination of seedlings 2 and 3.

Abstract

Robusta coffee seeds (Coffea canephora L.) require dormancy breaking treatment to accelerate germination. One of the treatments for breaking dormancy that can be done is chemical scarification by adjusting the concentration and duration of sulfuric acid (H2SO4) immersion. This study aims to determine the best concentration (H2SO4) and soaking time for breaking dormancy of robusta coffee seeds. This research was conducted in the Biology laboratory of the Faculty of Mathematics and Natural Sciences, Padang State University, in November-January 2022 using a two-factor completely randomized design. The first factor is the concentration of H2SO4 solution (0%, 10%, 15% and 20%). The second factor is the immersion time (25 minutes, and 50 minutes). Each treatment combination consisted of 4 replications. Parameters observed were germination percentage, germination rate, vigor index, hypocotyl length (cm), root length (cm), and dry weight (grams). The results showed that the H2SO4 concentration treatment had a very significant effect on the percentage of germination parameters, and dry weight while the other parameters had no significant effect. The treatment duration of immersion had a significant effect on the parameters of germination percentage, germination rate, and dry weight while the other parameters had no significant effect. The combination treatment between H2SO4 concentration and soaking time had a very significant effect on the germination rate parameter, significantly affected the germination percentage parameter, and had no significant effect on other parameters.

Abstract

Kale is a widely popular cultivated plant. One of the ways to cultivate kale is by using a hydroponic system. Hydroponic systems usually use inorganic chemical nutrients such as AB mix. As an alternative to suppress the use of inorganic fertilizers, liquid organic fertilizers are used, namely ecoenzyme. Ecoenzyme is a liquid extract from the fermentation of organic kitchen waste with a sugar substrate (brown sugar or cane sugar) added with water.This study aims to determine the influence of ecoenzyme on the height and number of leaves of kale plants cultivated hydroponically. This study is an experimental study with 5 treatments and 5 repetitions consisting of P1 (control), P2 (2 mL ecoenzyme + 1 L water), P3 (3 mL ecoenzyme + 1 L water), P4 (4 mL ecoenzyme + 1 L water), and P5 (5 mL ecoenzyme + 1 L water). The data obtained is analyzed with a variety of fingerprints (ANOVA) with a 5% DMRT Advanced Test. The results obtained from research that ecoenzyme affects the number of kale leaves with the highest average of 14.6 strands (P4).
