Abstract

Ponorogo (7°52'15.3"S, 111°27'44.5"E) has various typical landscapes. A total of 59 landslides occurred during 2012-2018 in those common areas. The most severe landslide occurred in Banaran, Pulung sub-district, which caused several deaths and material losses. This research aimed to predict the areas which have the highest landslide probabilities based on daily rainfall. The methods were applied are scoring in four parameters, including daily rainfall, slope, land type, and land use. The data sets obtained from a local government authority (BAPPEDA). The data were treated using ArcGIS, Map server for windows, PostgreSQL database, and framework pmapper. The results are a real-time map based on the website, which provided three main categories of landslide probabilities. The highest vulnerability level of landslide were located in villages of Munggung (7°50'46.4"S, 111°38'36.9"E), Bekiring (7°51'11.9"S, 111°39'31.0"E), Singgahan (7°52'26.1"S, 111°39'05.8"E), Bedrug (7°53'20.1"S, 111°38'53.4"E), Wagirkidul (7°52'11.0"S, 111°40'46.3"E), and Banaran (7°50'47.9"S, 111°40'49.2"E). The system based on the website can be updated real-time depends on four parameters mentioned. These current results expected as an early warning system for those all potential areas, especially during the rainy season.
