Abstract
The main objectives of this research are to evaluate and formulate land stability level zone and to formulate spatial planning in Padang city. Evaluation and formulation of land stability level in Padang city conducted using Geographic Information System (GIS) technique and MAFF-Japan Model for spatial planning in Padang city. The research result, show that there were four land stability zone levels in Padang city i.e zone of high land stability (18.613 ha), zone of medium land stability (15.256 ha), zone of low land stability (27,614 ha), and zone of very low land stability (7.633 ha). The land area that has been built-up in zone A (A1) (9.062 Ha) and the total area of zone A (18.613 Ha), so that zone A (A2) can still be developed for the built-up land is 9.551 Ha. The land area that has been built-up in zone B (B1) (2.080 Ha) and the total area of zone B (9.551 Ha), so that zone B (B2) can still be developed for the built-up land is 8.923 Ha. While the zone C that has been built-up is 5.465 Ha. The unsuitable characteristics of zone C as the built-up land and potentially large enough to occur landslides, then all development in zone C (C1, C2, C3 and C4) (5.462 Ha) need in relocated gradually to zone A or B.
