Abstract

Indonesia is one of the world’s largest producers of coffee and spices; however, the integration of these resources into innovative MSME products remains limited. Jember Regency, known as a center of robusta coffee and a producer of spices such as ginger, cardamom, and cinnamon, holds great potential that has yet to be fully utilized by micro-enterprises. This program aimed to enhance the competitiveness of coffee-based MSMEs through herbal coffee innovation training. The method used was a participatory-educational approach, consisting of a pretest, theoretical presentations, hands-on roasting and blending practice, organoleptic testing, and final evaluation. Participants were drawn from MSME actors and coffee farmer communities in the Jember area. Results showed a significant cognitive improvement, with average scores increasing from 36 to 80 (a 122% increase). Participants also showed improved hardskills in herbal coffee formulation, label design, and digital marketing. A blend of 10% ginger and 5% cardamom was rated highest in taste tests. This activity demonstrates that local resource-based interventions can effectively improve product competitiveness and MSME self-sufficiency.

Abstract

Introduction: The limitation of endosperm in seeds requires the propagation of Dendrobium orchid plants to be carried out using in vitro culture techniques. The composition of in vitro culture media needs to be considered because it greatly determines the success of plant propagation. The addition of sucrose and myo-inositol to the growth media can support the growth of explants planted in vitro. This study aimed to determine the best concentration of myo-inositol and sucrose added to the multiplication medium to increase the growth of Dendrobium orchid explants. Methods: This study used a Completely Randomized Design. The experimental treatments were the concentration of myo-inositol and sucrose added to the VW media consisting of four levels, namely myo-inositol 50 mg/l + sucrose 20 mg/l, myo-inositol 50 mg/l + sucrose 40 mg/l, myo-inositol 100 mg/l + sucrose 20 mg/l and myo-inositol 100 mg/l + sucrose 40 mg/l. Observation variables include plant height, shoot emergence time, number of shoots and shoot growth rate. Data were analyzed using analysis of variance (ANOVA) at 5% α level and Duncan's Multiple Range Test (DMRT) at 5% level. Results: The addition of 40 g/l sucrose + 50 mg/l myo-inositol to the in vitro culture medium was the best treatment in producing optimal explant growth. Conclusion: The addition of 40 g/l sucrose can reduce the addition of myo-inositol to VW media by up to 50% to propagate Dendrobium orchids in vitro.

Abstract

Applying environmentally friendly technology in melon cultivation aims to create sustainable agriculture. Nutrient and plant growth regulators management are simple to apply and have a relatively rapid effect on melon fruit production. Water footprint assessment in melon cultivation is crucial for ensuring sustainable agricultural practices and efficient water use. This study aimed to evaluate the electroconductivity of nutrient solutions and GA3 concentration in increasing fruit production and water footprint efficiency. This research was conducted from June to September 2022 at Tefa SGH Polije. This research used a completely randomized design with treatments that consisted of nine combinations of nutrient solution electrical conductivities (2.8, 3.2, and 3.6 mS cm-1) and GA3 concentrations (0, 60, and 120 mg L-1). Observation variables were fruit diameter, edible part thickness, fruit sweetness level, fruit weight, and water footprint. Data were analyzed using ANOVA and DMRT. Applying 2.8 mS cm-1 nutrient solution (NS) + 60 mg L-1 GA3 was the best treatment according to fruit diameter, edible part thickness, and fruit sweetness level. Although statistically, it had no significant effect, 2.8 mS cm-1 NS + 60 mg L-1 GA3 increased fruit weight by 18.75% and water footprint efficiency by 15.48% compared to control.
