Abstract

Edamame is a vegetable commodity whose export demand is currently increasing, while its productivity is still below its potential yield. Therefore, to meet export needs, it is necessary to increase productivity by applying boiler ash, which can improve soil fertility and increase the availability of nutrients in the soil. Research aimed at increasing the growth and yield of edamame by applying various doses of boiler ash was conducted at the Teaching and Research Farm, Faculty of Agriculture, Jambi University, at an altitude of 35 meters above sea level. The research used a one-factor Randomized Block Design (RBD) with various doses of boiler ash, consisting of 0 tonha-1; 5 tonha-1; 10 tonha-1; 15 tonha-1; and 20 tonha-1. Each treatment was replicated 5 times. The research results showed that the application of boiler ash was able to increase plant height, the number of young pods per plant, the weight of young pods per plant, the weight of 100 young pods per plant, and edamame production per hectare. A boiler ash dose of 20 tonha-1 resulted in the highest edamame growth and yield.

Abstract

Young jackfruit waste accounts for around 70% of its total weight in the form of skin and straw, which is typically discarded, indicating that it has the potential to damage the environment. Young jackfruit skin waste comprises lignocellulose, including cellulose (38.69%), hemicellulose (20.80%), lignin (26.50%), and water (11.13%). This composition is most likely to be utilised as biological charcoal as a raw material for the production of Biobriquettes, which are a valuable renewable energy source. The objective of this research is finding the best concentration of tapioca adhesive for manufacturing Biobriquettes from juvenile jackfruit skin. The research was carried out at the Agricultural Engineering Laboratory.The research is divided into five stages: preparation of young jackfruit skin waste, carbonisation and sieving process, adhesive manufacturing, biobriquette making, and biobriquette printing. The study used a Completely Randomised Design with four (four) treatments and five (five) replications, specifically administering tapioca adhesive concentrations (25%, 30%, 35%, and 40%). The parameters observed include water content, ash content, volatile substances, resistance, initial flame time and flame duration.The research Data were analysed using ANOVA, followed by Duncan's New Multiple Range Test at the 5% level. The best biobriquette results were obtained by utilising a concentration ratio of young jackfruit peel charcoal and adhesive of (75:25%), with a water content of 5.16%, ash content of 7.96%, volatile compounds of 12.29%, durability of 0.40%, time The initial flame lasted 6.33 minutes, while the flame duration was 113.98 minutes. These results comply with Indonesian National Standards (SNI 01-6325-2000)

Abstract

Boron is a micronutrient that plays an important role in plant growth and development. This research aims to determine the response of several varieties to the application of different doses of boron fertilizer and to obtain the best dose for each variety. The experiment was arranged in a randomized block design with a two-factor factorial pattern with two replications. The first factor is three varieties of green beans (Kutilang, Vima 2, Sampoeng) and the second is five levels of boron fertilization doses (0 kg ha-1, 1,5 kg ha-1, 3,0 kg ha-1, 4,5 kg ha-1, 6,0 kg ha-1). The variables observed are growth, yield and yield components variables. Data were analyzed using analysis of variance and Duncan's test, each at the 5% level. The optimum dose for each variety was obtained through second order (quadratic) regression analysis. The results show that there are differences in the response between the three varieties to boron fertilizer in the variable seed weight per plant. The influence of varieties can be seen independently on all variables, the influence of boron fertilizer has an independent influence on all variables except the number of primary branches. The optimum dose of boron for the kutilang variety is 2.39 kg ha-1, the Vima 2 variety is 3.36 kg ha-1, and Sampoeng, 3.19 kg ha-1.
