Abstract

This research aims to map social vulnerabilities and affected areas after the earthquake in Sumedang Regency. Social vulnerability was mapped using scoring adapted from the Regulation of the Chairman of the National Disaster Management Agency number 2 of 2012 which researchers modified according to existing data in 2024. Social vulnerability data is population density, sex ratio, vulnerable age group ratio, population ratio poor and disabled population ratio. The affected areas were mapped using field surveys and visualized using Geographic Information System (GIS) software. However, previous studies have not yet integrated dynamic post-disaster social changes or validated the vulnerability classifications with real-time community resilience indicators. Based on research, it was found that Sumedang Regency has 11 sub-districts including high classification, 8 sub-districts with medium classification and 7 sub-districts with low classification. The high classification of social vulnerability is in the central urban area of Sumedang Regency and the southern area bordering Bandung Regency. The survey results show that an area with a radius of 2 km is a very vulnerable area, a radius of 4 km is vulnerable and 6 km is medium. Based on the results of the analysis, it was found that areas with high social vulnerability and those affected by earthquakes were very vulnerable, namely North Sumedang District, Cisarua District, Cimalaka District and Ganeas District.

Abstract

Sub-DAS Mahakam Hilir di Kalimantan Timur mengalami degradasi lingkungan akibat deforestasi, alih fungsi lahan, dan aktivitas antropogenik yang memengaruhi ketersediaan air tanah. Penelitian ini memodelkan potensi air tanah menggunakan pendekatan overlay multiparameter berbasis Sistem Informasi Geografis (SIG) dengan mempertimbangkan curah hujan, jenis tanah, geologi, kemiringan lereng, tutupan lahan, dan NDVI. NDVI dihitung dari citra Sentinel-2 dan diklasifikasikan menjadi lima kelas. Validasi menggunakan 29 titik sumur bor menunjukkan akurasi model sebesar 89,7%. Daerah berpotensi tinggi berada di dataran rendah berendapan aluvial, sedangkan wilayah berbatu keras menunjukkan potensi rendah. Analisis NDVI tahun 2020–2025 menunjukkan penurunan kerapatan vegetasi sebesar 9,56%. Hasil korelasi menunjukkan hubungan yang sangat lemah dan tidak signifikan antara potensi air tanah dan NDVI (R² = 0,1018). Hal ini menunjukkan bahwa kerapatan vegetasi tidak berbanding lurus dengan potensi air tanah, dan faktor geologi serta topografi lebih dominan memengaruhinya.

Abstract

Flooding is one of the natural disasters that often hit East Jakarta City. In the context of disaster preparedness, students' knowledge and attitude are very important. This study aims to identify the influence of students' knowledge on flood preparedness in public high schools in East Jakarta City. In addition, this study also wants to explore the influence of learners' attitudes on disaster preparedness, and analyze the relationship between knowledge and attitudes in the context of preparedness. In this study, cluster random sampling technique was used with a total of 311 students. Data collection methods included observation, tests, questionnaires, interviews, and documentation studies. To analyze the data, various techniques were used, including testing of research instruments, prerequisite analysis, multiple linear regression analysis, and hypothesis testing. The results showed that the knowledge about flooding possessed by public high school students in East Jakarta City can be categorized as high, reaching 82%. This includes understanding, application, analysis and evaluation. Meanwhile, students' attitudes in dealing with flood disasters are in the medium category, at 76%, with components of accepting, responding, appreciating, and being responsible. Learners' preparedness is also in the moderate category with a percentage of 70%, which includes disaster risk knowledge, emergency response plans, disaster warning systems, and resource mobilization. From the analysis of the coefficient of determination (R²), an R² value of 0.544 was obtained. This shows that knowledge and attitude have an influence of 54.4% on disaster preparedness.
Pemetaan Sebaran Tingkat Bahaya Dan Laju Erosi Di DAS Brantas Tahun 2025 Menggunakan Metode RUSLE ( REVISED UNIVERSAL SOIL LOSS EQUATION) Kurniasih, Mirna; Azhari, Desy Fitriani; Hudzwah, Rifdah Ashma; Rohmat, Dede; Handayani, Tiara

Abstract

Erosi tanah merupakan permasalahan utama yang mengancam kelestarian Daerah Aliran Sungai(DAS) Brantas, Jawa Timur. Aktivitas pemanfaatan lahan yang intensif tanpa memperhatikanprinsip konservasi tanah memperparah laju degradasi lahan di kawasan ini. Penelitian inibertujuan untuk memetakan sebaran tingkat bahaya dan laju erosi di DAS Brantas tahun 2025menggunakan metode Revised Universal Soil Loss Equation (RUSLE). Parameter RUSLE yangdigunakan dalam penelitian ini meliputi faktor erosi hujan (R), erodibilitas tanah (K), panjangdan kemiringan lereng (LS), penutup lahan (C), serta tindakan konservasi (P), yang seluruhnyadiolah secara spasial dengan bantuan Sistem Informasi Geografis (SIG). Hasil analisismenunjukkan bahwa laju erosi di DAS Brantas sangat bervariasi dengan kategori bahaya erosimulai dari rendah hingga sangat berat. Sebaran bahaya erosi tertinggi umumnya terkonsentrasidi wilayah perbukitan yang mengalami konversi lahan hutan menjadi lahan pertanian dengankemiringan lereng curam serta minimnya penerapan konservasi lahan. Temuan ini menunjukkanpentingnya penguatan konservasi lahan terpadu berbasis spasial untuk menekan laju degradasitanah di DAS Brantas secara berkelanjutan. Hasil penelitian ini diharapkan dapat menjadi acuandalam perencanaan pengelolaan DAS yang lebih efektif.
