Abstract

The limestone formations are a unit of geological rock formations that are important for the formation of unique Karst Landscapes but are often threatened by development interests, one of which is in the environment around Goa Peteng, whose existence is threatened. This research aims to investigate: 1) the conditions of limestone formations  around Goa Peteng, 2) identified threats to the existence of limestone formations  around Goa Peteng, and 3) potential opportunities for protecting the existence of limestone formations  around Goa Peteng. The methods used in this research include field observation, literature review, and assistance with map digitization. This assistance involves utilizing literature studies, both scientific articles and reports containing maps that also cover the study location. The results of the research show that the limestone formations in the Goa Peteng environment exist at of a level of karst development in the Goa Peteng environment which is Mesokarst and parts of the surrounding area are Non-Karst apart from that there is Exokarst Potential and Endokarst though not much exists at the study location. The real threat to the existence of the karst landscape in the Goa Peteng environment is the development of mass tourism in the form of tourist accommodation such as hotels and villas, which has developed rapidly over the last 14 years, as seen from Satellite Image data. The limestone formations in the Goa Peteng environment themselves has the opportunity to be a place for education and further studies need to be carried out on the limestone formations and karst development in South Bali

Abstract

Denpasar City is the capital of Bali Province, located in the southern part of Bali Island. The population growth rate in Denpasar City from 2021 to 2022 reached 0.12%, with a population density of 5,727 people per square meter in 2022. This high population growth rate naturally impacts the demand for land for both residential and activity purposes, indirectly posing a potential risk for flooding problems. According to BPBD Denpasar City, there were 37 flood incidents in 2018 and 5 flood incidents in 2020. This study aims to map flood threats in Denpasar City, Bali Province. The method used is the Analytical Hierarchy Process (AHP), which assigns weights and scores to each flood parameter and then overlays them. The weighting and scoring of each flood parameter are based on related research. The flood parameters used include slope gradient, land cover, rainfall, drainage density, and soil type. The overlay results produce a flood threat map with five classifications: very low with an area of 1.17 ha, low with an area of 121.35 ha, medium with an area of 2210.41 ha, high with an area of 6970.29 ha, and very high with an area of 3178.92 ha.

Abstract

This quantitative research aims to identify areas with flood potential in Candikuning Village, Baturiti District, Tabanan Regency. The study was conducted from September 2023 to May 2024. It covers various variables relevant to flood potential, namely rainfall, slope gradient, land use, soil type, and drainage density. To identify flood-prone areas in Candikuning Village, each parameter was scored based on predetermined classifications according to their respective categories. This process involved an in-depth analysis of the collected data. Once these parameters were classified, the next step was to overlay them with the Candikuning Village Administrative Map. In this study, weighted overlays were used to combine data on rainfall, slope gradient, land use, soil type, and drainage density. Each layer of information was weighted based on its importance in contributing to flood potential. The final result of this study is a flood potential map depicting areas in Candikuning Village with varying levels of flood risk. The classifications on this map are divided into five main categories: very low potential, low, medium, high, and very high. This flood potential map is expected to serve as a useful tool for local government and the community in planning flood mitigation measures, as well as in the effective management of natural resources and spatial planning.
