Abstract

This research aims to determine the flood intensity in Makassar City, which is influenced by several factors, including land use, slope gradient, land cover, and rainfall. The research method is a quantitative approach using spatial analysis to examine spatial phenomena. The spatial analysis was conducted using an overlay method with a scoring technique to map each variable that affects flood intensity. The analysis results indicate that the flood intensity in Makassar City is categorized into three levels: low, moderate, and high.. The analysis results suggest that in Makassar City, 37.4 km² or 21% of the total area falls into the low rainfall intensity category. In contrast, the moderate rainfall intensity category encompasses 73.3 km² or 41% of the city, while the high rainfall intensity category represents 68.1 km² or 38% of the total area. This research has implications for efforts to control the pace of regional development that influences and potentially exacerbates flooding, thereby enabling early mitigation of environmental issues.

Abstract

The diversity of teaching materials in the current era is experiencing very rapid development, so that the selection of appropriate teaching materials will have an impact on student learning outcomes. The purpose of this study was to analyze the results of the application and determine the improvement in student learning outcomes in the implementation of teaching materials based on ArcGIS StoryMaps. The results of initial observations conducted at SMA Negeri 12 Makassar showed that teachers still use teaching materials in the form of books, power points and websites that are less interactive so that this has an impact on student learning outcomes that are lacking. The method in this study uses N-Gain analysis to measure student learning outcomes. The data collection technique in this study was divided into two classes, namely the experimental class and the control class with 20 samples each through pre-test and post-test. The results of this study are 1. based on the results of the average pre-test, the experimental class score was 52 and the control class 34 while the average post-test score in the experimental class was 73 and the control class 35. 2. Based on the results of the normality test (N-Gain) showed that the experimental class was 0.56 and the control class was 0.8. This shows that there has been an increase in students' understanding in the use of teaching materials based on ArcGIS StoryMaps, especially in the material on the Distribution of Flora and Fauna in Indonesia

Abstract

The increase in population results in an increase in the amount of water supply needed to carry out all activities of the population.  Groundwater is a very important alternative source, especially during the dry season. This research aims to determine the distribution of groundwater potential in Pangkajene Regency and the islands which can be used as a reference and information regarding areas that have groundwater potential. By using the overlay method through the use of geographic information systems. This method is carried out by scoring each parameter used, namely giving a value and weighting according to the classification of each parameter. The analysis process was carried out with the help of the ArcGIS 10.8 mapping application. Based on the results of the analysis carried out in this research, it was found that Pangkep Regency as a whole has a moderate level of groundwater potential, this can be seen from the percentage of 60.26% of the total area of ​​Pangkajene Regency or around 476.4302954 km2 has groundwater potential. which is being. In this case, the government needs to carry out regular monitoring and evaluation of groundwater conditions in areas with medium potential including Tondong Talassa, Minasa Tene, Pangkajene, and Bungoro sub-districts to ensure that the quality and quantity of groundwater do not decline to low or very low. As well as carrying out detailed exploration and inventory of groundwater potential in areas with high levels such as in the Mandalle, Marang, and Labakkang subdistricts.
