Abstract

The purpose of this study is to investigate the utilization of organic waste of green mustard and crab waste as materials for producing liquid organic compost. This study was conducted in experiment station and laboratorium of Chemistry, Faculty of Agriculture, Fisheries and Biology, University of Bangka Belitung in February 2014. The design of experiment used randomized block design with formulation ratio as treatment. The treatments consist of F1 (100% green mustard organic waste), F2 (75% green mustard organic waste + 25% crab waste), F3 (50% green mustard organic waste + 50% crab waste) and F4 (25% green mustard organic waste + 75% crab waste). The results showed that green mustard organic waste and crab waste could produce quality of liquid organic compost in accordance with the Indonesian National Standard (SNI 19-7030-2004). All formulations between green mustard organic waste and crab waste, including F3 (50% green mustard organic waste + 50% crab waste) produced liquid organic waste in accordance with the Indonesian National Standard (SNI 19- 7030 2004).

Abstract

R. cinerea leaf is one of leaves with anti-fungi compound that is able to inhibit the growth of C. capsici. This research is aimed to know the impact and the effectiveness as anti-fungi of R. cinerea leaf extract in inhibiting the growth of C. capsici on the chili seeds. This research was conducted at Biology Laboratory, Experimentation and Research Station of the Faculty of Agriculture, Fishery and Biology Bangka Belitung University. The experimentation was carried on Januari 2014 to April 2014. The experiment was conducted in two stages, using randomized completely design with 6 level of treatment (research I), and 4 level of treatment (research II), and 3 replication. Observation data were analysed using analysis of variance (ANOVA) with the level of significance 95%. If the result showed significantly effect, it continued to be tested with Duncan’s Multiple Range Test (DMRT) (research I), and the Least Significance Difference (LSD) (research II). The result showed that the concentration of R. cinerea extract has significantly impact in inhibiting the growth of C. capsici on the chili seeds. The most effective concentration was found on the level of concentration 35% (90,9%) with the least percentage of affected seeds.

Abstract

The research aimed to find the appropriate plant spacing and weeding period to onion growth and production in ultisol land. Furthermore, the objective of the research is to identify interaction between plant spacing and weeding period and its effect to onion growth and production. The experiment conducted in May 2014 – July 2014 in Experimental Field, Faculty of Agriculture, Fisheries and Biology, Bangka Belitung University. It used Factorial Completely Randomized Design with two factors and three repeated. First factor is plant spacing, consist of J1 (10 x 15 cm) and J2 (20 x 15 cm). Second factor is weeding period, consist of P0 (without weeding), P1 (weeding in 7 day after palnting), P2 (weeding in 14 day after palnting), P3 (weeding in 21 day after palnting), P4 (weeding in 28 day after palnting), P5 (weeding to harvest time). The result showed plant spacing 20 x 15 cm and weeding period until harvest time give the great result to onion growth and production. Furthermore, it showed that no interaction between plant spacing and weeding period.

Abstract

Agricultural activities always produce solid waste which originated from residues of livestock and crop. Chicken feathers and banana trunk are waste that have potential to be utilized as compost material. It is due to chicken feathers contains high protein so that it can be used as a source of nitrogen. Meanwhile, banana trunk contains high potassium. Decomposition of compost material needs a lot of time. However, composting can be conducted faster by using microorganisms. The purpose of this study is to determine the effect of banana trunk and the effectivity of local microorganism in the decomposition of compost material. This study uses randomized block design factorial with six treatments. First factor is banana trunk (0.5 and 1 kg). The second factor is activator types (EM4, MOL tapai and MOL papaya).The variables were temperature, water content, color, pH, N-total, C-organic, ratio C/N, phospor, and potassium. The result showed that banana trunk was statistically significant to water content, ratio C/N and potassium. Furthermore, the activators did not affect physical and chemical properties of compost.

Abstract

The use of edible coating is a way to increase the shelf life of horticultural products. This study aims to determine the effect of the application of beeswax emulsion coating concentration with the addition of sesame oil and lemongrass oil as an edible coating to extend the shelf life of tomatoes. This research was conducted in January ̶ March 2020. The experimental design used was a Randomized Block Design (RBD) with various concentrations of beeswax emulsion combination of 0,5% lemongrass oil and 0,5% sesame oil with various concentrations of beeswax (0%, 1%, 2%, 3%). Beeswax edible coating solution is applied to the tomatoes by dipping the tomatoes into the solution. The results showed that the application of beeswax emulsion edible coating with the addition of sesame oil and citronella oil to tomatoes with a concentration of 3% was able to maintain the fruit's shelf life for 12 days of storage and gave good results on weight loss, total dissolved solids and total acid variables in tomatoes compared to other treatments.
