The distance between one biopori point and the other is 50 cm with a depth of 20-25 cm. It is expected that by making this biopori can improve the planting media and water can seep up to be able to reach the root zone area. If the planting media and water absorption are sufficient, then the growth of grass will be even better. Other improvements will be carried out simultaneously to meet the provisions and completeness in force.
