. Pyroclastic materials derived from Merapi volcano eruption caused physical damage on land resources (crops, water, and livestock) and socio-economic life of communities in the affected areas. Solving problems and restoration of land affected by the eruption should be performed gradually and comprehensively based on community ability and government support. The role of technology and the existing research results could be considered as one of the alternatives to improve productivity of land covered by Merapi eruption deposits. Volcanic ash falling on land surfaces experienced cementation and hardness and caused high soil bulk density (BD), while the total pore space (RPT) and soil permeability decreased. Erosion control by growing Flemingia congesta, C. calotirtus, and Gliricidia in a manner that parallel to contour line. In addition, Bahia grass and bamboo plants are used to stabilize sandy land and reclamation of the former Merapi lahar. The technology for increasing the productivity of volcanic land can be done by planting animal feed grass on the ridge or riser. This is also useful to control soil erosion, increase land quality, crop production, and livestock feed.
