Abstract

The population in Bandung continues to increase and its growth results in increasing necessities of plant products. Meanwhile, field availability is decreasing so a certain process of intensification in agriculture is needed. One of the ways of doing it is by creating plant bioreactors. The purpose of this study was to obtain the effect of composition and size variation of the bed on the parameters of hold up liquid to improve plant production. Fluid flowing is based on the concept of hold up liquid from a bed with medium consisting of compost and sand with various sizes (not sifted; 4 - 2 mm; 2 - 1 mm; 1 mm - 500 μm; 500 - 250 μm and 250-125 µm) and composition variations (100: 0; 25:75; 50:50; 75:25 and 0: 100) from compost and sand. The results showed that the bed consisting of sand and compost with a ratio of 25:75 with a diameter of 500 - 250 μm as a good composition in increasing the hold up liquid value of a bed with 0.75 hold up.
