Abstract

English

Panimbang sub-district is one of the areas affected by the tsunami in 2018, located directly opposite the Krakatau Volcano and close to the Sunda Strait subduction zone (megathrust), making it an area with a high threat of tsunami levels. This study aims to determine the impact of coastal forests in reducing tsunamis using COMCOT modeling as one of the mitigation efforts. The tsunami generator used uses the worst scenario earthquake that can occur in the Sunda Strait subduction zone area. The results show that the coastal forest in Panimbang sub-district with a width of 380 m can reduce the tsunami velocity by 50% compared to the coastal forest with a width of 30 m. In addition, the manning coefficient (n) value also has an influence in reducing the inundation area, inundation level height, and tsunami velocity.

Kecamatan Panimbang merupakan salah satu wilayah yang terdampak tsunami pada tahun 2018. Letaknya yang berhadapan langsung dengan Anak Gunung Krakatau dan berada dekat dengan wilayah zona subduksi (megathrust) Selat Sunda menjadikannya sebagai wilayah dengan tingkat ancaman tsunami yang tinggi. Penelitian ini bertujuan untuk menganalisis peran hutan pantai dalam mereduksi tsunami menggunakan pemodelan COMCOT sebagai salah satu upaya mitigasi. Pemodelan dilakukan dengan menggunakan skenario terburuk gempabumi yang berpotensi terjadi di zona subduksi Selat Sunda. Hasil penelitian menunjukkan bahwa hutan pantai di kecamatan Panimbang dengan lebar 380 m dapat mereduksi kecepatan tsunami hingga 50% dibandingkan dengan hutan pantai hanya selebar 30. Selain itu, nilai koofisien manning (n) juga berpengaruh signifikan dalam mereduksi luas genangan, ketinggian level genangan, dan kecepatan tsunami.
