The impact of economic losses and heavy casualties made the tsunami worth watching out. Ecosystem-based tsunami disaster mitigation efforts are deemed necessary, considering that 2/3 of Indonesia consists of the sea. The coral reef is one of the coastal ecosystems that can reduce tsunami waves by up to 50% before it hits coastal areas. However, the current condition of coral reefs is very alarming due to the actions of irresponsible humans. Collaboration between stakeholders is needed to carry out ecosystem-based tsunami disaster mitigation efforts. Collaborative governance becomes an essential issue in efforts to build and improve services in the public sector by involving all relevant stakeholders. The sectoral ego of the stakeholders is no longer relevant to be maintained because each actor has their strengths and weaknesses. Collaboration between actors framed in a collaboration platform by having a principled engagement, shared motivation, and collective capacity will produce better results. Keywords: Tsunami; Collaborative Governance; Mitigation; Coral Reef INTRODUCTION The natural disasters phenomenon of earthquake and tsunami that occurred in Indonesia some time lately has received attention from various parties and must be anticipated by all stakeholders (Amagai et al., 2014; Bragg et al., 2018; Neumayer & Plümper, 2007; Sorooshian, 2005; Yamamura, 2013; Yanagisawa et al., 2016). Disaster mitigation efforts are essential because Indonesia's geographical location is in areas prone to earthquakes and tsunamis. Astronomically, Indonesia as an archipelago state is known as the "Emerald of Equator," positioned at 07N - 12S and 95E - 141E Longitude. This position makes Indonesia has a tropical climate that has enough rainfalls which make it a fertile land. Tropical forests flourish in Indonesia, which stores both biological and animal richness. Geographically, Indonesia is also in a strategic position, placed between 2 continents (Asia and Australia) and two oceans (Indian and Pacific). Geologically, Indonesia, which is located around 3 (three) tectonic plates, namely Indo-Australia, Eurasia, and the Pacific which collide with each other and produce magma activity in the bowels of the earth. Indonesia's territory that is passed by the tectonic plate is mostly located on the south side or in the Pacific Ocean, as can be seen in Figure 1. The boundary area between tectonic plates where the intersecting plates are areas that have active tectonic conditions, and when one tectonic plate moves, it can cause earthquakes, magma activity in the bowels of the earth increases. This magma activity became the forerunner to the birth of 127 active volcanoes in Indonesia.
