Abstract
The limestone mining area is a karst area that has an important ecological function as a water conservation area. After the mining process, the ex-mining area becomes critical land that is poor in nutrients, decreases soil microbial diversity, increases soil pH and temperature. This study aimed to examine the use of conventional and block compost based on plant height parameters and stem diameter. Block compost was made using the bokashi method with the ingredient of teak leaf litter (Tectona grandis). The composition of leaf litter (30%), manure (40%), and sawdust (30%). Block compost is made by adding adhesive and it is made using a pressing device. Block compost application on plants is very effective compared without block compost. The average plant height with block compost is 163.2 cm, while without block compost is 27 cm. the average of stem growth diameter of plants with block compost of 1.61 cm, while without block compost was 0.71 cm. This shows that block compost is a solution in mining land reclamation.
