The thickness of volcanic ash after an eruption of covering agricultural land can be divided into 4 classes, namely: thin (the thickness < 2 cm), medium (thickness 2- 5 cm and thick (> 5 cm). Efforts for the recovery and rehabilitation land on each cluster based on the thickness of the dungeon ashes were normal processing with a hoe or plow, fertilizing with of organic matter and to the lava, dungeon needs to be done the conservation and land rehabilitation by an annual plant / the forest.
