Abstract

Land cover undergoes changes every year. Such development might be uncontrolled, making it crucial to monitor changes in land cover. Monitoring land cover changes can be conducted using satellite imagery, especially Landsat images. This study was conducted in the Katobu District, Muna Regenvy, and aimed to: (1) identify changes in land cover from 2017-2022 in the Katobu Subdistrict, Muna District; (2) analyze the direction of built land development from 2017-2022; (3) understand the factors influencing the direction of built land development. The data used in this study include the type of land cover from Landsat images, sample coordinate points from field surveys, and data on factors affecting the direction of built land development obtained from interviews. The data analysis methods used are overlay and quantitative descriptive. The research results include: (1) the most significant land cover change from 2017-2022 was the transformation from shrub land to built land, with a change of 27,86 hectares or 2,84%; (2) the direction of built land development in the Katobu Subdistrict from 2017-2022 tends to head towards the Batalaiworu Subdistrict; (3) the influencing factors are non-physical factors such as population growth/total population and city activities.

Abstract

Changes in land use can affect the Total Suspended Solids (TSS) in river water. Higher erosion levels due to land clearing result in increased TSS levels. This study was conducted at the Wanggu River Basin Estuary in 2014 and 2023, with the aim of understanding land use changes, determining TSS distribution, and assessing the impact of land use changes on TSS levels. The data used include land use maps from 2014-2023 derived from Landsat imagery for 2014 and 2023, and TSS data obtained from field surveys. The data were analyzed using overlay and quantitative descriptive methods. The results of the study indicate that the total land use change in the Wanggu River Basin from 2014 to 2023 covers an area of 6,570 hectares (19.28%) of the total Wanggu River Basin area. The highest land use change occurred in forest areas, which decreased by 2,054.39 hectares (6.03%), while the smallest change occurred in water bodies with a reduction of 5.72 hectares (0.02%). The TSS levels in the Wanggu River Basin Estuary increased at 13 observation stations from 2014 to 2023, with the largest TSS change occurring at station 3, where levels rose from 85,439 mg/l (2014) to 142,609 mg/l (2023). The land use changes from 2014 to 2023 have influenced the increase in TSS levels in the Wanggu River Basin due to the significant reduction in forest areas, which has led to higher erosion rates.
