Abstract:
The objectives of this research are to compare the quality of the black grass jelly powder between laboratory scale and scale up experiment and to define their process efficiency. Tool that had been used is extractor with 100 Littre capacities, while the raw materials are 5 kg dried grass black leaf and 75 littre water. From the organoleptic tests (30 general panelist), it can be seen that there are no significant differences quality between laboratory scale and scale up experiment in color, odor, flavor, and texture. Moreover, from proximate test for grass black jelly powder, it can be observed that there are no significant differences in all parameters. Furthermore, grass black jelly powder for scale up contains water, carbohydrate, crude fiber, and yield in the amount of 12.25%; 43.7%; 5.89%; and 16.28% respectively. In addition, from energy efficiency analysis, it can be measured that from boiling, draining, evaporating, drying, and milling process, the efficiency are 85.11%, 76.97%, 99.64%, 99.99% respectively. Utility needs for each batch are 0.1 m3 water that cost Rp 220.5, 20,01 Kwh electricity that cost Rp 18,569.28, and 30Kg LPG that cost Rp 234.000,00. In brief, the total cost is Rp 252,789.78.
