Abstract

Sumatra Island is the sixth-largest island in the world, with an area of 443,068.8 km2. West Sumatra often experiences earthquakes due to the subduction route, or the India-Australia and Eurasian tectonic plate route, the Mentawai Fault System on the western part of the West Sumatra Coast, and the Sumatran Fault Segment, as happened in West Pasaman Regency. The earthquake in West Sumatra was in Kenagarian Kajai, Talamau District, West Pasaman Regency. This research aim to obtain spatial information in the Kenagarian Kajai area, Talamau District, West Pasaman, which will later be implemented in the form of a map. This multispectral drone can produce images that can be processed digitally, so they can present images of objects that are simpler but informative in classifying them. By using drones, it is possible to obtain topographic measurement data with the same quality as terrestrial measurements but in a relatively shorter time.  Pulau Sumatera merupakan pulau terbesar keenam di dunia dengan luas mencapai 443.068,8 Km2. Sumatera Barat sering mengalami gempa bumi, akibat adanya jalur subduksi atau jalur lempeng tektonik India-Australia dan Eurasia, Mentawai Fault System di bagian Barat Pantai Sumatera Barat, dan Segmen Sesar Sumatera, seperti yang terjadi di Kabupaten Pasaman Barat. Gempa bumi di Sumatera Barat yaitu Kenagarian Kajai, Kecamatan Talamau, Kabupaten Pasaman Barat. Dalam penelitian ini, kami menggunakan wahana peminderaan jauh berupa drone multispektral untuk memetakan tutupan lahan dan bertujuan untuk mendapatkan informasi spasial di wilayah Kenagarian Kajai, Kecamatan Talamau, Pasaman Barat yang nantinya akan diimplementasikan dalam suatu bentuk peta. Drone multispektral ini dapat menghasilkan citra yang dapat melakukan pemrosesan secara digital, sehingga dapat menyajikan gambar-gambar objek yang lebih sederhana namun informatif dalam  mengklasifikasikannya. Dengan menggunakan drone sangat dimungkinkan untuk mendapatkan data pengukuran topografi dengan kualitas yang sama dengan pengukuran secara terrestrial akan tetapi delam waktu yang relative lebih singkat. Kata Kunci: drone multispektral, pemetaan, tutupan lahan

Abstract

Siberut Island is one of the areas prone to earthquake and tsunami disasters in West Sumatra. This area has a high accumulation of stress, which has the potential to cause large earthquakes and tsunamis. To reduce this risk, disaster mitigation is needed and in this case the Mentawai people have local wisdom which is used as an Early Warning System. The aim of this research is to analyze the use of Geographic Information Systems (GIS) to determine the tsunami inundation hazard index in tsunami disaster mitigation efforts and to analyze the role of Teteu Amusiat Loga local wisdom as an Early Warning System. This research uses a mixed method design with a quantitative and qualitative approach that combines spatial and SWOT analysis. Descriptive analysis using the SWOT method was carried out by looking at internal and external factors in local wisdom-based disaster mitigation which were then identified with the elements of Strength, Weakness, Opportunity and Threats. From this research, it was found that the high tsunami inundation hazard area of ​​10m was 14143.81 ha, 15m total 19737.38 and 20m 25154.3 ha with a total hazard area of ​​59035.49 ha. In this case, local wisdom has an important role in disaster mitigation, one of which is through the song Teteu Amusiat Loga which is used as an Early Warning System, but there is a level of knowledge related to this song in various age groups. The research results also explain that mass media and modern communication platforms provide opportunities to develop local wisdom, but this local wisdom is not in accordance with modern standards for disaster mitigation.
