Abstract

Indonesia merupakan salah satu negara dengan tingkat kerentanan tinggi terhadap bencana alam, khususnya banjir yang terjadi hampir setiap tahun. Provinsi Jawa Barat tercatat sebagai wilayah dengan frekuensi kejadian banjir yang tinggi, dipengaruhi oleh kondisi geografis serta tingginya jumlah penduduk. Penelitian ini bertujuan untuk menganalisis tingkat kerentanan sosial terhadap bencana banjir di Provinsi Jawa Barat menggunakan pendekatan Multicriteria Decision Analysis (MCDA) melalui perbandingan bobot Analytic Hierarchy Process (AHP) dan bobot berdasarkan Peraturan Kepala BNPB No. 02 Tahun 2012. Analisis dilakukan dengan memanfaatkan bahasa pemrograman R serta pengembangan aplikasi web interaktif berbasis R Shiny untuk menyajikan visualisasi spasial hasil analisis. Hasil pembobotan menunjukkan bahwa pada metode AHP, kepadatan penduduk memiliki bobot tertinggi sebesar 0,349, diikuti oleh rasio kelompok umur sebesar 0,216, rasio jenis kelamin sebesar 0,160, rasio penduduk cacat sebesar 0,159, dan rasio penduduk miskin sebesar 0,116. Sementara itu, metode BNPB memberikan bobot dominan pada kepadatan penduduk sebesar 0,6 dan bobot yang sama pada variabel lainnya sebesar 0,1. Perbedaan pembobotan tersebut menghasilkan perbedaan klasifikasi Indeks Kerentanan Sosial (IKS). Berdasarkan bobot BNPB, selama periode 2021–2024 diperoleh 78 wilayah kategori rendah, 24 wilayah kategori sedang, dan 6 wilayah kategori tinggi. Sebaliknya, berdasarkan bobot AHP tidak terdapat wilayah dengan kategori tinggi, dengan 49 wilayah berada pada kategori rendah dan 59 wilayah pada kategori sedang. Pemilihan metode pembobotan berpengaruh signifikan terhadap nilai dan klasifikasi IKS. Metode AHP menghasilkan penilaian yang lebih proporsional terhadap seluruh indikator berdasarkan penilaian para ahli dan kondisi lokal, sedangkan metode BNPB menekankan dominasi kepadatan penduduk sebagai standar nasional.

Indonesia is one of the countries with a high level of vulnerability to natural disasters, particularly floods that occur almost every year. West Java Province is recorded as a region with a high frequency of flood events, influenced by its geographical conditions and large population. This study aims to analyze social vulnerability to flood disasters in West Java Province using a Multicriteria Decision Analysis (MCDA) approach by comparing the weights derived from the Analytic Hierarchy Process (AHP) and those stipulated in the Regulation of the Head of the National Disaster Management Agency (BNPB) No. 02 of 2012. The analysis was conducted using the R programming language and the development of an interactive web- based application using R Shiny to present spatial visualizations of the results. The weighting results show that under the AHP method, population density has the highest weight (0.349), followed by age group ratio (0.216), sex ratio (0.160), ratio of disabled population (0.159), and ratio of poor population (0.116). In contrast, the BNPB method assigns a dominant weight to population density (0.6), while the other variables are equally weighted (0.1). These differences in weighting lead to different classifications of the Social Vulnerability Index (SVI). Based on the BNPB weights, during the 2021–2024 period, 78 regions were classified as low vulnerability, 24 as moderate vulnerability, and 6 as high vulnerability. Conversely, using the AHP weights, no regions were classified as highly vulnerable, with 49 regions classified as low vulnerability and 59 as moderate vulnerability. These findings indicate that the choice of weighting method significantly affects the SVI values and classifications. The AHP method provides a more proportional assessment of all indicators based on expert judgment and local conditions, whereas the BNPB method emphasizes the dominance of population density as a national standard.
