Abstract

Agricultural land in Indonesia was largely dominated by untapped potential land, almost of that potential land is dry land. Maize (Zea mays L.) is one of the staple crops that are known could be cultivated on dry land. Rizosphere has been known to containmicroorganisms that can improve the plant growth. In the previously study, we have screenedin vitro of rhizobacteria (6 isolates of Pseudomonas sp CRB and 7 isolates of Bacillus sp CR) as growth promoter of maize and drought tolerant. A total of 6 rhizobacterial formula were further applied in vivo in greenhouse to promote the growth of maize. In planta test on maize showed that formula CRB 19 and F3 (CR 83 + CRB 10) were the best formula that could enhance plant growth parameters under drought stress conditions. After that abundance and activities of microbe were analyzed by enumeration of total fungus, bacteria and actinomycetes, dehidrogease test, soil respiration test dan C-microbe test and those tests showed that formula CRB 19 and F3 (CR 83 + CRB 10) were the best formula.These formula could be recommended as inoculants of maize planted in dry land agriculture.

Abstract

This study aims to determine the optimal concentration of Bacillus licheniformis required in the formation of liquid sugar from cassava waste, the value of sugar and value starch contained in degraded cassava skin waste. The design used in this study was Completely Randomized Design (RAL) with 4 treatment concentration of cassava leaf extract (Manihot utilissima Pohl.), Ie 0 concentration, 1.5 ml concentration, 2.5 ml concentration and 3.5 ml of concentration B. licheneformis. Data were analyzed using analisis (ANOVA) followed by Duncan's range test (DMRT) with a 5% confidence level. The results of the study showed that all treatments had a significant effect on the administration of B. licheniformis concentrations. Treatment using 1.5 ml B. licheniformis concentration on cassava skin substrate weighing 1 gram after Duncan's test range (DMRT) with 5% confidence level resulted Reduction sugar value of 6.07%.

Abstract

Angso Duo Market is the largest traditional market in the city of Jambi, with an area of ​​± 5 Ha. The amount of waste produced by Angso Duo market every day is around 105 tons per day with a ratio of 70% biodegradable waste, 25% recycled (organic and paper) and 5% other waste. Of the 75% of waste that is around 60% is waste in the form of vegetables, most of which are mustard and cabbage. Vegetable waste has great potential to be used as organic fertilizer because it has good and complex nutrients such as protein, fat carbohydrates, calcium, phosphorus, iron, vitamins A, B and C, folic acid, fiber, water and sodium. The advantage of liquid organic fertilizer is that it contains enough nitrogen as a constituent of plant protein and chlorophyll. The results showed 6 types of bacteria namely Planococus, Neisseria, Halobacter, Azomonas, Azotobacter and Bruccella which were formulated into liquid fertilizers with a basic substrate of vegetable cabbage and mustard waste.Then tested the ability of bacteria to dissolve nitrogen, phosphorus and potassium as potential bacteria as liquid fertilizer
