The Strategic Model of Tsunami Based in Coastal Ecotourism Development at Mandeh Regions, West Sumatera, Indonesia

摘要

The aim of this research is to formulate the strategic model of tsunami based in coastal ecotourism development. The danger zones of tsunami formulation was using the analytical method of Geography Information System (GIS) through GIS analysis equipment-GLOBAL MAPPER to modify and stimulate the contour through the height of tsunami’s wave 10-20 m, while to formulate the danger zones of this was conducted by using GIS-ERDAS 9.1 and GIS-ArcGIS 9.1 (Hermon, 2012 b , Hermon 2014 c ; Hermon 2015). This strategic model formulation of ecotourism development through tsunami based was conducted by A’WOT method, that is a mixture analysis of Analytical Hierarchy Process (AHP) and SWOT analysis (Kanges et al., 2001; Hermon, 2010 a ; Pelz, 2014; and Hermon 2014 d ). Generally, Mandeh regions are included in the risk zones of high tsunami and medium zones. The risk zones of high tsunami are included coastal region of Marak Island, west coastal region of Sironjong Kecil Island, north coastal region of Carocok Tarusan Bay, west, north and south coastal region of Cubadak Island, and west coastal region of Pagang peninsula. Meanwhile, the risk zones of medium tsunami are included east coastal region of Sironjong Kecil Island, east coastal region of Cubadak Island and west Sironjong Gadang, Setan Kecil and Gadang islands, Pagang islands and south coastal region of Carocok Tarusan Bay. The strategic model of tsunami based in ecotourism development showed that IFE (Internal/Strength Factor and Weaknesses Evaluation) had a score of 1,678 and EFE (External/Chance Factor and Threat) had a score of 2.371. EFE score is higher than IFE. It showed that tsunami based of ecotourism development of Mandeh regions has a big strengths and chances to be done.
