Optimization of Pineapple Waste Fermentation Process in Continuous Reactor System

ABSTRAK

The aim of the present study is to investigate the influence of variations in substrate flow rate and supply O2 in fermentation process by utilizing Acetobacter xylinum. The experiments were carried out on a laboratory scale continuous reactor system operated at room temperature , 25OC-27OC, with a pH of 4.5. The parameters analyzed include BOD5, COD, TPC (sel/mL), ash, weight (GSM), fiber length (mm), fines (%) dan cellulose total content. Data analysis showed that those variations influence the nata layer formation. The best result obtained for nata layer is 3 mm with the characteristic of the pulp from nata is cellulose total content values of 62.34%. The values of fiber length and fines are 0.537 mm and 27.25 %, respectively. While the results obtained for removal efficiency of BOD5 is 49.90% and the values of COD is 50%. Treatment variation that gave the best cellulose was at time detention of 12 days with bacteria growth percentage of 80%. The utilization of pineapple waste study as raw material to produce pulp by utilizing Acetobacter xylinum has not yet been established. This preliminary research will contribute to improve the quality of nata de pina layer.
