The coast of Jailolo is a tourism area that has the potential of natural resources, namely the potential of village tourism. Developing village tourism potential greatly supports economic activities in increasing community income. The high potential for geological disasters has a negative impact on the Jailolo coastal area, especially village tourism destinations. The low level of community resilience to geological disasters is limited information and a need for more data on disaster risk in the Jailolo coastal area. Therefore, maximum efforts should be made to increase community knowledge related to tourism optimisation, reducing the impact and risk of geological disasters. For mitigation efforts to be maximally and well coordinated, a tourism development strategy is needed on the potential of village tourism on the coast of Jailolo based on disaster mitigation, including multi-risk mapping of geological disasters on the coast of Jailolo. The resulting multi-risk map can be used for safe planning and safe land use and reduces the risk of geological disasters in the Jailolo coastal tourism area. The method used was an exploratory and evaluative survey method with a quantitative approach. Primary data sources were collected by surveying vulnerable communities using questionnaires and interviews to obtain information on capacity. Data processing was carried out in the form of scoring and then mapped with the help of QuantumGIS software. The data analysis technique refers to the Regulation of BNPB No. 2 of 2012 on Disaster Risk Assessment. It uses the Multi Criteria Analysis method with the help of Geographic Information System (GIS) software. The results showed that the Jailolo coastal tourist destination has a high risk of earthquake and tsunami disasters (score 3, red colour). Earthquake and tsunami multi-risk mapping in the Jailolo coastal tourist destination area, West Halmahera, is one of the strategies for developing disaster mitigation-based tourist destinations.

Pangkalan data paleo-tsunami Indonesia mencatat tanggal 28 Juni 1859 terjadi gempabumi kuat di Laut Maluku dengan skala intesitas (MMI) IX dan menyebabkan tsunami di Teluk Sidangoli dengan ketinggian 10 meter. Laut Maluku memiliki pengaruh yang signifikan terhadap potensi terjadinya bencana tsunami di sekitar wilayah Halmahera termasuk Jailolo Selatan. Melihat adanya potensi bencana tsunami yang besar di wilayah Jailolo Selatan, maka perlu dilakukan strategi perencanaan mitigasi bencana tsunami yakni dengan pemodelan bahaya tsunami. Pemodelan bahaya tsunami dilakukan untuk mengetahui nilai amplitudo maksimum (Run-up) gelombang tsunami dengan menggunakan perhitungan numerik dari sofware Cornell Multi-Grid Coupled Tsunami Model (COMCOT) versi 1.7, nilai jarak maksimum yang dapat ditembus oleh air pasang ke daratan pada pantai yang datar (inundasi), dan nilai sudut kemiringan lereng (slope) dari pengukuran fotogrametri udara Unmanned Aerial Vehicle (UAV). Hasil Pemetaaan bahaya tsunami menghasilkan nilai amplitudo maksimum (Run-up) setinggi 4 meter dan wilayah yang terdampak akibat gelombang tsunami berjarak (inundasi) sekitar 310 meter dari garis pantai. Nilai rata-rata sudut kemiringan lereng (slope) di pesisir Jailolo Selatan adalah 22,90 dan termasuk lereng curam. Dan slope tipe curam cenderung menyebabkan peningkatan tinggi gelombang saat tsunami mendekati pantai, sehingga gelombang dapat menjadi lebih tinggi.

Kolorai Village is a National Strategic Tourism Area (KSPN) influenced by complex tectonic activity. The low community resilience to earthquake disasters in Kolorai Village means that the government must refrain from using disaster risk factors as a reference in developing disaster mitigation-based tourism areas. This research aims to analyse the risk of earthquake disasters in the tourism area of Kolorai Village. Problem-solving in this research uses the survey method and descriptive analysis with a quantitative approach. Primary data or field data in the form of vulnerability and capacity data are obtained using the help of checklist instruments, questionnaires, and interviews. The earthquake disaster risk analysis results in Kolorai Village have a score of 3. They are included in the high category with a percentage of hazard factors of 43%, 28% vulnerability, and 29% capacity. The value of earthquake disaster risk is produced as a map that illustrates the elements of earthquake disaster risk in the Kolorai Village Tourism Area. So that it can be used for spatial planning, it needs to be integrated with disaster risk reduction.

Earthquake hazard mapping in the North Maluku region is urgent and essential because this area has a very high earthquake hazard potential. The high level of earthquake vulnerability in the North Maluku region makes it very important to focus mitigation activities to reduce the impact of earthquakes that occur. Earthquake hazard mapping that illustrates the effects of earthquakes on an area is one of the disaster mitigation efforts. In this study, earthquake intensity using the Probability Seismic Hazard Analysis (PSHA) method will be used to analyse the level of earthquake hazard in the North Maluku region. The results of the distribution of Peak Ground Acceleration (PGA) values for North Maluku range from 0.67 - 3.75 g. At the same time, the value of the MMI earthquake intensity scale is in the range of IX-XII. The most incredible earthquake intensity is in the Morotai, West Halmahera, Ternate, Tidore, Bacan, and Obi Island areas. The results of this study can have implications as a reference in safer spatial and infrastructure planning, the preparation of more effective mitigation strategies, and can be a medium for educating the public to be more prepared and responsive to earthquake risks.

The coastal area of Ternate Island has a high potential for tsunami disasters and complex tectonics. The tsunami on Ternate Island was triggered by an earthquake in the Maluku Sea and the eruption of Mount Gamalama under the sea. The rapid development of Ternate, especially in the tourism sector, such as Loto Agrotourism Village, West Ternate, demands attention to the safety of visitors and residents. The main problem in Loto Village is the lack of evacuation routes, so an effective evacuation strategy is needed to minimize losses during a tsunami disaster. This study aims to determine evacuation routes using UAV data and participatory mapping in Loto Village, Ternate City. UAV aerial photos were processed using photogrammetry techniques with Agisoft Metashape Professional software, producing Ortho-Mosaic Maps and Digital Elevation Model (DEM), which were analyzed in QGIS software. The ortho-mosaic map was overlaid with a tsunami hazard map to create temporary evacuation routes and points (TES), which were confirmed through participatory mapping. The Final Map shows four TESs, which are accessible via footpaths, side roads, and main roads. In the event of a tsunami, tourists and residents in the Lota Agrotourism area can use this map for evacuation. The map can also be an important reference for the government in forming disaster mitigation policies to ensure the safety of tourist destinations that are vulnerable to tsunamis.
