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 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

In Indonesia, rice is the staple food of most homes in urban and rural areas. Management of post-harvest activity has an important role on the rice seed quality at the storage period. One of the solutions to overcome seed deterioration is to perform invigoration. It can be conducted in some methods; those are osmoconditioning, hydration-dehydration, and matrioconditioning. The purpose of this study is to determine the effects and interaction of storage duration and invigoration toward seed viability and vigor of Bangka local rice accession Mayang. This study was conducted in the Laboratory of Agrotechnology, Faculty of Agriculture, Fisheries and Biology, University of Bangka Belitung form November 2012 to January 2014. Completely Randomized Design Factorial (CADF) was used as design of experiment of this study. The first factor is the storage duration (L) that consist of 3 treatment levels those are L7 = storage duration (7 months), L8 = storage duration (8 months) and L9 = storage duration (9 months), while the second factor is the invigoration treatment which consist of 4 treatment levels, those are K = controls, P = osmoconditioning using PEG 8000, H = hydration-dehydration and A = husk. The results showed that treatment of storage duration and invigoration statistically significant to the seed viability and vigor of Bangka local rice accession Mayang. However, there was no interaction between storage duration and invigoration. The best result was storage duration of 7 months for seed viability and vigor, while hydration-dehydration method was the best result on invigoration treatment.

Abstract

Growth of in vitro seedling Phalaenopsis orchid can be enhanced by using ½ Murashige and Skoog (MS) medium which was supplemented with organic additive. The purpose of this study is to investigate the effects of organic additives in the ½ MS medium and to determine the best organic of organic additives on Phalaenopsis seedling growth. Culture medium (½ MS) was supplemented with coconut water, banana pulp, carrot extract, tomato extract and pineapple extract. The results showed that ½ MS medium supplemented with coconut water 100 ml/L could increase growth of Phalaenopsis orchid to the number of roots and wet weight. In addition, ½ MS medium supplemented with 200 g/L showed statistically significant to the leaf length. Furthermore, coconut water is the best organic additive for development of in vitro seedling Phalaenopsis orchid.
