Abstract

Mapping of slums in Indonesia uses a survey-based mapping method. This method requires a lot of time and money, especially when updating data, especially during the current pandemic, it will be risky. Based on the Minister of PUPR Number 14/PRT/M/2020. Over the last 6 years (2014-2020), the mapping of slums cost 382 billion. In addition, the main disadvantage of the survey method is the inconsistency of the results due to the interpretation of surveyors in different fields. To overcome this problem, remote sensing-based slum identification with a machine learning approach with the help of High-Resolution Satellite Imagery (CSRT) and support vector machine (SVM) features can quickly and cheaply calculate slum areas. Therefore, the objectives of this study are (1) Identifying the distribution of slums using machine learning methods based on Satellite Imagery in Padang City. Based on the description above, it can be concluded that the level of slums in the identified areas of slum settlements in Padang City is predominantly light category. There is only one ward, Teluk Kabung Selatan, which is at the medium category. Slums not always squatter which is proven by the ownership status of the land certificate. Pasar Ambacang Ward has the most families in slum settlements (1.112 families). Meanwhile, Tarantang Ward has the smallest slum families in the identified slum area (25 families). Based on the results of the analysis using support vector machine and field verification, slums were identified in 45 (forty-five) villages spread across 11 sub-districts with a total area of 129.16 hectares. This condition is supported by the centralization of activities in the core village of Padang City, which creates a development gap with the hinterland area.

Abstract

Indonesia is a developing country with a population growth rate of 1.38%. Due to the relatively strong population growth every year, this greatly affects land change. Therefore, the phenomenon of land use change emerged. In general, the rate of population growth correlates with the rate of land use change, which results in increased satisfaction of land-use needs such as settlements and public facilities. This study aims to determine the Change in Land Cover resulting from the Change of Agricultural Land Function into developed land and where the direction of changing agricultural land to developed land in Batang Anai District. This study uses a quantitative approach by utilizing Remote Sensing using Object-Based Classification (OBIA). Based on the interpretation results on Sentinel-2A images in 2017 and 2022, 8 land cover classes were found with an Overall Accuracy of 91% and a Kappa Index of 89.80%. Agricultural land in Batang Anai District has undergone land conversion into built-up land of 304.2 Ha or 8.70% of the agricultural land area in Batang Anai District with a total of 3499.16 Ha so that the remaining agricultural land area in 2022 is 3194.96 Ha. As a result of the land use change, there was a development of built-up land which was converted into housing development, public facilities and the Padang-Pekanbaru toll road leading from South to North.

Abstract

Land cover change is a process of change from previous land cover to other land cover and is also long or temporary in nature which is a form of logical consequence of growth and transformation. The purpose of this study was to identify and determine land cover in Batang Anai Sub-district. The research method uses the overlay method, map analysis approach and also regression statistics, namely Landsat images of land cover of the study area in 2002 and 2022 sourced from the Research Center. Significant changes in the area of each category reflect major shifts in the land use structure of the area over the period 2002 to 2022. An increase in urban and wet-rice farming, along with a decrease in the area of shrubs, are highlighted. The driving factor for land change in the Batang Anai sub-district is caused by people who want to increase their income from existing land by expanding their plantation or agricultural land and also building built-up land.

Abstract

The tendency of people to live in river basins will trigger the growth of settlements and human activities that require more land. This causes an increase in land requirements in river basins. As a result, there is a change in land use around the river basin, which was originally a vegetated forest area to become non-vegetated, resulting in a decrease in the carrying capacity of the watershed. This research aims to determine how much land cover has changed in the Sumpur watershed over the last 10 years (2014-2024). This type of research is quantitative with a spatial descriptive approach. The method for making land cover maps for the Sumpur watershed is supervised classification. Meanwhile, the method used to calculate the area of land cover change is through the calculate geometry tool. The results of the research show that land cover changes occurred in the Sumpur watershed from 2014 to 2024. The most extensive increase in land change occurred on built-up land and moors/fields. Meanwhile, other types of land cover such as forests, rice fields and mixed gardens tend to experience a decline. Land previously used for agriculture or forests was converted into built-up land for various development purposes.
