Increasing population in Bandung will cause the need for products from plants also increase, while the available land decreases so that it is necessary to intensify the process in agriculture. One of them is by making plant bioreactors that can facilitate availability of water and nutrients in the land. The purpose of this study is to obtain the influence of bed variations on hold up liquid parameters of a bed. The tests included hold up liquid tests of various bed variations consisting of variations in size (not sieved; 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 in order to get a good ratio of bed between sand and compost on hold up liquid in the soil. The total sample obtained is 30 samples. Based on the experimental results, it was concluded that the sand and compost with a ratio of 25: 75 and diameter of 500 - 250 μm as a good composition to increasing the holdup liquid value of bed with 0.3 hold up liquid.
