Indonesia is a country at the southeastern edge of the Eurasia Continent that has geologically complex conditions. Located at the meeting point of the world plates, this country lies in a zone of high tectonic activity. As a consequence, it is highly vulnerable to natural hazards, such as earthquakes and tsunamis. For instance, Ternate Island in the east of Indonesia is prone to tsunamis. This study intends to map tsunami susceptibility in the coastal areas of Ternate Island. The mapping stages were as follows: weighting and scoring of each parameter and, then, data processing based on Geographic Information System (GIS) using the overlay features in ArcGIS software. The results identified a higher susceptibility to tsunamis in the southern coastal area than the southwestern one. Several influencing factors of tsunami susceptibility on the island are elevation, slope gradient, and coastal material roughness.
The implementation of Integrated Coastal Management (ICM) requires concern from various sides. Semarang City is the main activity and economic center in the north of Central Java, Indonesia, and this status presents a significant challenge to realizing ICM based on coastal ecosystems, such as mangroves. This paper qualitatively examines the collaborative practice of various stakeholders in Semarang City in applying ICM to disaster risk reduction based on mangrove ecosystems. Intensive development has created a stumbling block to various stakeholders in mangrove ecosystems management. Also, this city is at high risk of coastal disasters like tidal floods, land subsidence, and social-economic problems of coastal communities. This situation requires the integration of various stakeholders to realize the ICM in the coastal areas of Semarang City effectively. In actualizing mangrove management practices as part of disaster risk reduction, some stakeholders are involved, namely the governments, universities, communities, and the private sector from the international, national, regional, and local level.
