Initial Assessment of Geomorphological Vulnerability Index in Supporting Sustainability Tourism in Small Island, Case of Gili Ketapang, East Java, Indonesia

Muh Aris Marfai, Bambang Suriadi

Aside from being known as the most preferred tourist destination, small island is a unique geomorphological unit due to its isolation and limited natural resources. Activities several issues and challenges to face with in developing small island management. Gili Ketapang is the only island in regency of Probolinggo, East Java and one of the main destination in the region. The objectives of this research are to assess the geomorphological susceptibility and geomorphological resilience as the initial assessment of geomorphological vulnearability index in Gili Ketapang to support the sustainability tourism in the island. This research was carried out in two coasts in the island which are the western and eastern coast whose different kind of activities. Scoring method was used to determine the value to each variables which were scored from 0 to 4. The result showed that the geomorphological suscepbility index of western and eastern coast were high with the index of respectively 0.781 and 0.831. The geomorphological reslience index was quite low in the western coast with the index of 0.125 whereas the western coast possessed high resilience with index of 0.875. It indicates that even in the small islands, the consideration of geomorphological conditions for sustainable development and environmental protection were necessary. Further research related to geomorphological exposure to complete the geomorphological vulnerability is expected to carry out in teh future.
