Abstract

Letusan Gunung Sinabung yang terletak di Dataran Tinggi Karo, Sumatra Utara pada tanggal 9 Juni 2019 menyebabkan adanya kolom abu vulkanik berwarna hitam pekat dengan ketinggian mencapai ±7.000 m di atas puncak gunung. Kolom abu vulkanik itu tersebar hingga menyelimuti sekitar lima kabupaten di sekitar lokasi gunung api tersebut. Proses evakuasi perlu dilakukan untuk meminimalisir jumlah korban akibat peristiwa letusan ini. Proses evakuasi dapat dilakukan dengan mengetahui jejak persebaran dari kolom abu vulkanik. Ada beberapa cara untuk mengetahuinya, salah satu diantaranya adalah dengan menggunakan data dari citra satelit Himawari-8 yang diolah dengan memanfaatkan metode RGB (red-green-blue) untuk mengetahui dimana arah persebaran abu vulkanik berdasarkan arah gerak angin. Hasil penelitian yang dilakukan, dapat dengan baik mendeteksi pola persebaran dari kolom abu vulkanik yang terjadi. Sehingga dapat diketahui wilayah yang berpotensi terdampak dari sebaran abu vulkanik. Selain itu deteksi abu vulkanik, dapat pula dimanfaatkan oleh sektor penerbangan, dan juga mempermudah pendataan kerugian sosial-ekonomi yang timbul akibat sebaran abu vulkanik.

Abstract

This study analyzes the vulnerability to disasters and the preparedness index of coastal communities in Kupang City, Indonesia, in facing tsunami risks. Employing a quantitative descriptive method, the research evaluates vulnerability across four categories: physical, social, economic, and environmental. The preparedness index was assessed using variables such as community knowledge, emergency response planning, disaster warning systems, and resource mobilization. The findings reveal that Kelurahan Fatubesi and Oesapa exhibit high vulnerability due to physical and social factors, while other areas demonstrate moderate vulnerability. The overall preparedness index of coastal communities is classified as "nearly ready," with Oesapa Barat and Oesapa showing better preparedness levels compared to other areas. The study emphasizes the need for enhancing disaster awareness, improving infrastructure, and developing community-based risk management strategies to mitigate the impact of tsunamis on coastal populations.
