The meeting of the 3 world plates, the Eurasian Plate, the Indo-Australian Plate, and the Pacific Plate in eastern Indonesia, caused a high potential for earthquake and tsunami events in the area. The frequency of tsunami events in eastern Indonesia including West Papua Province is quite large. Tsunamis are mostly caused by earthquakes originating from the sea, but can also be triggered by submarine landslides, volcanic eruptions at sea, gas extrusions, celestial bodies, nuclear explosions and other generating sources. With the high potential of tsunamis in West Papua Province, tsunami hazard and risk maps are urgently needed to become a reference in the development planning process and tsunami disaster risk reduction activities that are more effective, efficient and integrated to reduce the possible impact of victims. The danger of a high tsunami in West Papua Province which has a far enough landward direction is on the coast of Sorong City, Sorong District, South Sorong District, Bintuni District and north of Fakfak District (Bomberay Sub-District). Based on the area of high-risk areas, Bintuni District is the district that has the widest high-risk area, with an area of 116,728 Ha or 5.61% of the total area of the Bintuni District, while Tambrauw District is the district with the smallest high risk area of 2,076 Ha or 0,32% of the total area. The only district that does not have a tsunami threat because it is not in the coastal area is Maybrat District.Keywords: tsunami, West Papua, hazard, risk, risk reduction ABSTRAKPertemuan 3 lempeng dunia, Lempeng Eurasia, Lempeng Indo-Australia, dan Lempeng Pasifik di Indonesia bagian timur, menyebabkan potensi tinggi kejadian gempa dan tsunami di daerah tersebut. Frekuensi kejadian tsunami di Indonesia bagian timur termasuk Provinsi Papua Barat cukup besar. Tsunami sebagian besar disebabkan oleh gempabumi bersumber di laut, tetapi juga bisa dipicu akibat tanah longsor bawah laut, letusan gunungapi di laut, ekstrusi gas, benda-benda langit, ledakan nuklir dan sumber pembangkit lainnya. Dengan tingginya potensi tsunami di Provinsi Papua Barat, maka sangat dibutuhkan peta bahaya dan risiko tsunami untuk menjadi acuan dalam proses perencanaan pembangunan serta kegiatan pengurangan risiko bencana tsunami yang lebih efektif, efsien dan terpadu untuk mengurangi dampak korban yang mungkin terjadi. Bahaya tsunami tinggi di Provinsi Papua Barat yang mempunyai pelamparan cukup jauh ke arah daratan terdapat di pantai Kota Sorong, Kabupaten Sorong, Kabupaten Sorong Selatan, Kabupaten Bintuni dan sebelah utara Kabupaten Fakfak (Kecamatan Bomberay). Berdasarkan luas area berisiko tinggi, Kabupaten Bintuni merupakan kabupaten yang memiliki area berisiko tinggi terluas, yaitu dengan luas 116.728 Ha atau 5.61% dari luas keseluruhan Wilayah Kabupaten Bintuni, sedangkan Kabupaten Tambrauw merupakan kabupaten dengan wilayah berisiko tinggi paling kecil dengan luas 2.076 Ha atau 0,32% dari seluruh luas wilayahnya. Satu-satunya kabupaten yang tidak memiliki ancaman tsunami karena tidak berada pada kawasan pesisir adalah Kabupaten Maybrat.Kata kunci: tsunami, Papua Barat, bahaya, risiko, pengurangan risiko

“…An earthquake with a magnitude of Mw 8.9 is the most significant predicted earthquake that could occur in the Central Java-East Java segment of Java Megathrust which could potentially cause a tsunami disaster. Tsunami inundation is the maximum distance of water that can reach land as a result of the propagation of tsunami [12]. The initial magnitude of the earthquake's momentum causes the wave height to vary, making it possible for the wave to destroy what it passes through on land [13].…”

The southern coastal area of Java Island is a subduction area confluence of the Eurasian Plate and the Indo-Australian Plate. The southern area of Temon District, Kulon Progo Regency includes the Central Java-East Java megathrust area. Megathrust Central Java-East Java has a maximum earthquake potential of 8.9 Mw which has the potential to cause a tsunami disaster. The built-up land area in Temon District has a potential threat from the danger of tsunami inundation. The purpose of this study is to (1) analyze the danger of tsunami inundation in Temon District and (2) determine the area of built-up land affected by tsunami inundation. The method used in this study is descriptive quantitative-qualitative. TUNAMI-N3 was used in numerical modelling to determine tsunami inundation hazards and Google Earth Engine was used in analyze built-up land in Temon District. The results of tsunami inundation hazard treatment and built-up land areas were analyze using ArcGIS 10.8 to determine built-up land affected by the potential tsunami inundation hazard. The results showed that the tsunami generated from the earthquake scenario with a magnitude of Mw 8.9 had a maximum height of 19.86 meters with an average travel time of 33 minutes to reach the coastal area of Temon District. Temon District affected by tsunami inundation hazard has a tsunami area of 2.47 km2 with details of a low tsunami danger level of 0.67 km2, medium tsunami danger of 0.95 km2 and high tsunami danger of 0.85 km2. The maximum height of the tsunami inundation bath is 6.54 meters. Temon District has a built-up land area of 14.308 km2. Built-up land affected by tsunami inundation is 0.55 km2 with details of 0.14 km2 at low danger of tsunami inundation, 0.20 km2 at medium danger of tsunami inundation and 0.21 km2 at high tsunami inundation hazard.

“…Tsunami has a very large force because of the huge volume of water and its fast speed. Tsunami may approaches the coast at around 48 km/ hour with its millions tons in strength [4]. This big wave power will cause serious disasters to the coastal communities.…”

Tidal turbines and seismographs constitute instruments that can be used as an earthquake detector that lead to tsunamis. As an early detection instrument for tsunami disaster, tidal turbine and seismograph are generally placed under the surface of the water. The design objective in this study is designing a Remotely Operated Vehicle (ROV) which can be used as a tool for tidal turbine and seismograph installation. The design method applied in this study is designing a prototype by following the product research and development procedures. Making control systems has three stages, namely: software design, hardware manufacture, and software and hardware integration. The made software includes the ROV motion control program through the control of Arduino Nano R2 ATMega microcontroller with programming that uses C-Basic language. The design findings show that the designed ROV can be used effectively to simulate the installation of tidal turbine and seismograph under the surface of the water in 2 meters at depth with 15 minutes of installation time in undulating water.
