Abstract
Pada tanggal 28 Januari 2014, bencana tanah longsor terjadi
di Kabupaten Jombang, Jawa Timur yang mengakibatkan 14
warga Desa Ngrimbi meninggal di tempat. Bencana terjadi disaat
malam hari dimana warga sedang tertidur di dalam rumah,
sehingga tidak sempat menyelamatkan diri. Di lokasi tersebut,
terdapat lima rumah yang berdekatan dengan bukit. Empat rumah
hancur akibat tertimbun tanah longsor. Besarnya longsoran tidak
diketahui. Untuk itu diperlukan sebuah penelitian yang dapat
mengetahui besaran dampak longsoran dari bencana tanah
longsor. Selain itu penelitian ini dilakukan untuk mengetahui
seberapa efektifkah penggunaan UAV-Photogrammetry dalam
mengetahui besaran tanah longor yang telah terjadi.Penelitian ini
menghasilkan peta bencana tanah longsor dan jumlah volume
longsoran. Besaran volume yang didapat UAV-Photogrammetry
sebesar 10527,032 m³ sedangkan perhitungan volume yang
dilakukan dengan menggunakan pengukuran teristrial sebesar
11491,708 m³. Dari kedua metode tersebut didapatkan selisih
sebesar 964.676 m³. Pada penelitian ini, pengambilan data
UAV-Photogrammetry membutuhkan waktu dan sumber daya
manusia lebih sedikit dibandingkan dengan menggunakan metode
teristrial tetapi biaya pelaksanaan yang lebih mahal.
============================================================
On 28th of January 2014 in Jombang, East Java. 14 villagers
in total were dead on the spot. When the incident happened,
residents were resting in their house, where there were not enough
time to save themselves. On the location, there were five houses
adjacent to the cliff. Four houses were destroyed due to
landslides. The volume collapsed during the landslide remains
unidentified.
Photogrammetry can help in measuring volume collapsed
during landslides. This study was conducted to determine how
effective the use of UAV-Photogrammetry in measuring the
amount of land that collapsed. Compared with the terrestrial
methode. This research resulted orthophoto map landslides, as
well as counting the number of collapsed volume. The amount of
volume obtained by UAV-Photogrammetry methode is 10527.032
m³. as a comparison, the volume calculation obtained by
terrestrial methode is 11491.708 m³ . Different volume is 964 676
m³. In this case the data retrieval process done by UAV needs
less time and human resources than terrestrial.
