Abstract

Payakumbuh City is a developing region in West Sumatra. The area has undergone changes in land use due to an increase in the population, leading to a reduction in rice fields as they are converted into residential areas. The aim of this research is to identify the characteristics of changes in rice field land use in Payakumbuh and predict changes in rice field land use by the year 2032. The study utilizes SPOT images from 2019, 2019, and 2022. Driving factors inputted into LanduseSim include main road accessibility, secondary road accessibility, existing settlements, and rivers. The analysis results indicate a consistent decline in rice field land use in Payakumbuh. There has been a shift in the function of rice fields, with the most significant change being the conversion of rice fields into residential areas. Based on the predicted analysis of rice field land use from 2022 to 2032, only residential areas experience changes, with an additional area of 283.43 hectares. The results of the land change prediction in 2032 this can be used as a planning input to focus more on regional imbalances in border area.

Abstract

Human conflicts with crocodiles have become a problem that affects crocodile conservation. Scientific publications on crocodile attack cases in Indonesia are still scarce and need validation, thus mitigation efforts for conflicts are not yet optimal. Tanjung Mutiara Subdistrict is an area with the highest incidence of human-crocodile conflicts in West Sumatra, as it has a natural crocodile habitat directly bordering densely populated settlements and community plantations. This research aims to map the distribution of estuarine crocodiles and the potential for conflicts in surrounding settlements. Data processing was conducted using Maxent software, and environmental variables included distance from the river, distance from the coast, distance from plantations, land cover (shrubland), elevation, and temperature. The Maxent software prediction results indicate that the distance from the river is the most influential variable, with an AUC (Area Under Curve) value of 0.863. The output values' range, approaching 1, signifies better predictions. Settlements with activities within one kilometer from the river and coast have the highest potential for human-crocodile conflicts.
