Abstract

Abstrak. Penelitian ini bertujuan untuk mendapatkan isolat bakteri yang mampu mengurai limbah tandan kosong kelapa sawit secara bertahap. Skrining tahap pertama pada Nutrient Broth dan Tandan Kosong Kelapa sawit yang dishaker 150 rpm selama 3 hari,dan diperoleh 18 isolat bakteri. Sedangkan pada skrining  tahap kedua  menggunakan Nutrient Broth ditambah Tandan Kosong Kelapa Sawit dan diperkaya dengan sisa medium tahap 1 (Nutrient Broth ditambah Tandan Kosong Kelapa Sawit yang telah didegradasi oleh 18 isolat)  dishaker  selama 3 hari dengan kecepatan 150 rpm, didapatkan 6 buah isolat bakteri. Menurut buku Bergey Manual of Determinative Bacteriology Isolat 1, isolat 2, isolat 3, isolat 5 dan isolat 6 termasuk kelompok ke 7 yaitu bakteri gram negatif aerobik bentuk kokus dan batang. Sedangkan isolat 4 termasuk ke dalam  kelompok ke 14 yaitu bakteri gram positif berbentuk kokus.   Kata Kunci : Isolasi, Limbah, Tandan Kosong Sawit

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
