Abstract

The increase in population and tourism in Kuta, North Kuta and Denpasar City has led to an increase in the need for land which in turn will lead to changes in land use. This triggers a change in land use from agricultural land to non-agricultural land. This study aims to analyze changes in land use in Kuta, North Kuta and Denpasar City from 2000 to 2020. Land use is classified into 7 types of land use with a guided classification technique. The data used is in the form of spatial data from Landsat 7 imagery in 2000 and Landsat 8 imagery in 2010 and 2020. The research was conducted in November 2022-January 2023 in Denpasar City. Based on the results of the study, it showed that there were changes in land use in 2000-2020, such as a decrease in the area of paddy fields by 4,334.01 ha (56.7%) and an increase in the area of settlements by 5,043.51 ha (69.3%).

Abstract

The declining amount of carbon stock occurs due to the reduction of aboveground biomass, the increase in population, and the development of urban development. This study aims to analyze changes in the spatial distribution of vegetation index, carbon stock distribution, and biomass carbon stock every 5 years from 2002 to 2022 in Kuta, North Kuta, and Denpasar areas. The method used in this research is Image processing with Partial least square (PLS) model and random forest (RF). The data used in the study include Landsat images with recording in 2002, 2007, 2012, 2017 and 2022. The results of this study show that Kuta and Denpasar areas have different values and patterns of spectral index changes every 5 years for the vegetation index used. The area of change in the spatial distribution of carbon stocks increased every 5 years from vegetated to non-vegetated areas. The biomass carbon stock decreased over 20 years from very low, low, medium and high categories to non-vegetated. This condition occurs due to the development of built-up land in the tourism area of Kuta, North Kuta, and residential areas in Denpasar City.

Abstract

Groundwater need is always increasing due to population growth, climate change, economic growth, and uneven water distribution, especially in the densely populated areas like Denpasar and Badung, which also has a large area of built-up land. Excessive and continuos use of groundwater can cause a decrease in its quality and quantity. Such conditions make the research of groundwater potential is important to do. The purpose of this research is to determine the distribution of groundwater potential in the Denpasar and Badung regions and compare the results with the actual conditions. The methods that are used in this research are the calculation of vegetation index, rainfall data, and DEM data using Remote Sensing. This research results in the form of maps of rainfall, slope, elevation, and maps of NDMI, NDWI, SAVI, GNDVI, NDVI, BSI, dan NDBI. The research showed that groundwater potential in the location is divided into five classes, which are Very low, low, medium, high, and very high. Areas with very low groundwater potential are dominated by West Denpasar, North Denpasar, and parts of South Denpasar. the low class dominates the Kuta area, medium class is spread throughout the region, high class dominates the North Kuta area, while the very high class dominates the lower part of South Denpasar and some parts of North Kuta.

Abstract

The Ubud Tourism Area is a tourism area which is located on a fairly high plateau but floods often occur, especially when rainfall is high. The parameters causing potential flooding in the Ubud Tourism Area are river distance, altitude, slope, rainfall, land use and soil type. The purpose of this study is to provide information on the distribution of potential flooding in the Ubud Tourism Area in the form of mapping related to the awareness of the public and tourists against flood disasters. This research was conducted in Ubud District from October 2022 to January 2023. The research method used is the scoring and weighting method as well as the overlay of the parameters that cause potential flooding. The OSM Tracker application is used for field checking by checking potential flood points spread out in the study area. The results of the study show that there are five classes of potential flooding, namely very low, low, medium, high and very high. The potential for flooding in the Ubud Tourism Area is dominated by the high class area of 1,844.21 ha (43.02%) of the total area of Ubud District. Then very low class area of 15.91 ha (0.37%), low area of 408.16 ha (9.52%), medium area of 1587.25 ha (37.02%) and very high 432.4 ha (10 .08%) of the area of the Ubud Tourism Area.
