SUITABILITY EVALUATION OF SPACE UTILIZATION BASED ON ENVIROMENTAL SUSTAINABILITY AT THE COASTAL AREA OF BUNGUS BAY IN PADANG CITY, INDONESIA

Abstract

This study aimed to evaluate the suitability of space utilization conducted in the coastal area of
Bungus bay. The research was conducted through field survey with a spatial approach using Geographic
Information System (GIS) in order to know the suitability of area allocations which were served as a protected
zone, utilization zone, and special zone. The results showed that zone II covers an area of 232,9 ha with a score
of 48,4 and zone II covers an area of 136,2 ha with a score of 23 was not-suitable served as utilization zone,
and zone III covers an area of 539,9 ha with a score of 61 was suitable served as utilization zone. Management
alternative for not-suitable category in the protected zone at location 8 can be managed by the establishing of
coast protection, establishing of stilt house, and the improvement of roads connected to the main road; On the
utilization zone of location 11, location 12, location 18, and location 23 can be managed by relocating the
settlement as far as >100 m from the coast, establishing of coast protection, establishing of stilt house, and
improving roads connected to the main road; On the special zone of location 1 can be managed by relocating
the distance limit of ship track and activity, making of settling ponds for waste discharging, and establishing
stilt house; and on the special zone of location 25 can be managed by relocating the distance limit of ship track
and activity, making of settling ponds for waste discharging, and dust suppression (wetting) during coal loading,
and unloading.
