Abstract

Abstrak Ketersediaan data geospasial yang akurat di tingkat desa merupakan elemen krusial dalam mendukung perencanaan pembangunan dan pengelolaan sumber daya secara berkelanjutan. Namun, keterbatasan teknis serta rendahnya literasi digital aparatur desa seringkali menjadi penghambat utama. Program pengabdian ini bertujuan untuk meningkatkan kapasitas pemetaan desa melalui pendekatan partisipatif berbasis Sistem Informasi Geografis (SIG) dan pengembangan WebGIS. Kegiatan dilaksanakan di Desa Kedungsari, Kecamatan Temayang, Kabupaten Bojonegoro, dengan melibatkan perangkat desa dan masyarakat setempat. Metode yang digunakan mencakup survei lapangan, diskusi kelompok, digitalisasi data menggunakan QGIS, serta pengembangan platform WebGIS interaktif. Hasil kegiatan menunjukkan Desa Kedungsari mempunyai sisteminformasi berbasis WEB  dengan data penggunaan lahan, infrastruktur, batas wilayah, dan persebaran penduduk. Program ini membuktikan bahwa kolaborasi teknologi dan partisipasi masyarakat mampu mendorong transformasi digital desa secara inklusif dan berkelanjutan serta mendukung proses pengambilan keputusan di tingkat lokal. Kata kunci: pemetaan partisipatif; WebGIS; data spasial; pembangunan desa; QGIS Abstract Accurate geospatial data at the village level is essential for effective development planning and sustainable resource management. However, limited technical capacity and low digital literacy among village officials often hinder its implementation. This community engagement initiative aims to strengthen spatial data infrastructure through a participatory mapping approach based on Geographic Information Systems (GIS) and the development of an interactive WebGIS platform. The program was conducted in Kedungsari Village, Temayang Subdistrict, Bojonegoro Regency, involving local officials and community members. The methodology included field surveys, focus group discussions, spatial data digitization using QGIS, and the design of a web-based GIS system. The results demonstrated a significant improvement in local awareness regarding the importance of spatial information, along with the creation of detailed digital maps covering land use, infrastructure, administrative boundaries, and household distribution. The WebGIS platform enables broader access to spatial information, enhances public transparency, and supports data-driven decision-making processes at the village level. This program illustrates how the integration of technology and community participation can foster inclusive and sustainable digital transformation in rural areas. Keywords: participatory mapping; WebGIS; spatial data; village development; QGIS.

Abstract

Flooding is a recurring environmental challenge in Pangkal Pinang City, influenced by both natural topographic conditions and increasingly intensive land use changes. This study aims to assess spatial flood risk using the Topographic Wetness Index (TWI) as a hydrological indicator derived from Digital Elevation Model (DEM) data. Through slope and flow accumulation analysis, TWI values were calculated and classified using the equal interval method into five classes: very low, low, medium, high, and very high. The results show that the majority of the area falls into the very low and low categories, indicating good drainage conditions. However, localized zones of high and very high TWI values were identified in Bukit Intan, Gabek, and Rangkui sub-districts. In Bukit Intan, high flood susceptibility is linked to large-scale land clearing for industrial areas, residential expansion, and fish ponds. In Gabek, extensive deforestation for new settlements contributes to increasing flood risks. Meanwhile, in Rangkui, the accumulation of water is exacerbated by the density of existing built-up areas and insufficient drainage infrastructure. These findings highlight the relevance of TWI as a spatial analysis tool to support urban flood mitigation planning, especially in areas undergoing rapid land conversion. The study emphasizes the need to integrate topographic analysis into urban development policies to ensure flood-resilient growth.
