Pengembangan WebGIS Potensi Bencana Longsor dan Banjir Berdasarkan AOI

RAMADHAN, TAUFIQ - Personal Name;

ABSTRAK

Bencana hidrometeorologi seperti banjir, gempa bumi dan tanah longsor
merupakan ancaman serius yang sering menimbulkan kerugian material maupun jiwa.
Penelitian ini bertujuan untuk memetakan tingkat kerawanan banjir dan longsor secara
spasial serta menyajikannya dalam platform Website Geographic Information System
(WebGIS) yang interaktif. Analisis spasial dilakukan dengan mengintegrasikan
parameter-parameter utama melalui proses geoprocessing berbasis GIS. Pada
pemetaan kerawanan banjir, digunakan empat parameter utama yang dibobotkan
menggunakan metode Analytic Hierarchy Process (AHP), kemiringan lereng, jenis
tanah, tutupan lahan, jenis batuan dan curah hujan. Sementara pada pemetaan
kerawanan longsor, digunakan lima parameter: tutupan lahan, kemiringan lereng,
curah hujan bobot 30%, jenis batuan/geologi, dan jenis tanah. Data presipitasi CHIRPS
diolah menggunakan metode interpolasi geostatistik Kriging untuk menghasilkan
sebaran curah hujan kontinu yang akurat. Seluruh parameter diselaraskan ke dalam
sistem proyeksi koordinat WGS 1984 UTM Zone 48S dan dianalisis melalui tools
Intersect, Reclassify, dan Calculate Geometry. Hasil analisis menghasilkan peta zonasi
potensi kerawanan yang diklasifikasikan ke dalam 5 tingkat kerawanan (Sangat
Rendah, Rendah, Sedang, Tinggi, dan Sangat Tinggi). Informasi spasial ini berhasil
diintegrasikan ke dalam antarmuka WebGIS berbasis Group Layer yang dilengkapi
fitur kontrol Layer, legenda interaktif, dan estimasi luas wilayah rawan guna
mendukung sistem dan pengambilan keputusan kebencanaan.

ABSTRACT

Hydrometeorological disasters such as floods, earthquake and landslides pose a
serious threat that often results in material losses and loss of life. This study aims to
spatially map flood and landslide vulnerability levels and present them on an
interactive Geographic Information System (WebGIS) platform. Spatial analysis was
conducted by integrating key parameters through GIS-based geoprocessing. For flood
vulnerability mapping, four main parameters were weighted using the Analytic
Hierarchy Process (AHP) method, slope gradient, soil type, land cover, rock type, and
rainfall. Meanwhile, for landslide hazard mapping, five parameters were used: land
cover, slope gradient, rainfall weighted at 30%, rock type/geology, and soil type.
CHIRPS precipitation data were processed using the Kriging geostatistical
interpolation method to generate an accurate, continuous rainfall distribution. All
parameters were aligned to the WGS 1984 UTM Zone 48S coordinate projection
system and analyzed using the Intersect, Reclassify, and Calculate Geometry tools.
The analysis results produced a potential vulnerability zoning map classified into five
vulnerability levels (Very Low, Low, Moderate, High, and Very High). This spatial
information was successfully integrated into a Group Layer-based WebGIS interface
equipped with Layer control Features, an interactive legend, and estimates of the area
of vulnerable regions to support disaster and decision-making systems.
