Abstract

Banjir merupakan bencana yang terjadi di daerah yang memiliki cekungan dan curah hujan yang tinggi. Penyebab terjadinya banjir adalah perubahan fungsi tutupan lahan, penurunan permukaan tanah, besarnya volume debit air sungai, drainase yang kurang dalam atau sempit, curah hujan yang tinggi, dan bertambahnya bangunan-bangunan yang mengambil alih fungsi lahan. Penelitian ini bertujuan untuk mengetahui desa mana saja yang tergolong dalam daerah rawan bencana banjir di Kecamatan Sukasada. Variable – vatiabel yang digunakan dalam penelitian ini adalah curah hujan, kemiringan lereng, elevasi, penggunaan lahan, dan bentuk lahan. Dalam proses identifikasi daerah rawan banjir ini, menggunakan metode skoring dan pembobotan dengan memberikan nilai skor dan bobot pada masing-masing parameter, kemudian melakukan analisis tumpang tindih (overlay) pada Peta Curah Hujan, Kemiringan Lereng, Penggunaan Lahan, Elevasi, Bentuk Lahan serta Peta Administrasi Kecamatan Sukasada, sehingga mendapatkan 3 klasifikasi kerawanan banjir yaitu, kelas yang berkategori kurang rawan banjir, rawan banjir, dan sangat rawan banjir.

Abstract

The land surface is part of the space whose existence is limited, therefore it is necessary to use the land surface in a planned and controlled manner. Judging from this, a situation mapping will be carried out which includes measuring Infrastructure and Topography Measurements in the Ganesha Education University campus environment in Bali Province, Buleleng District, Buleleng Regency. more detailed mapping will require more sophisticated technology, namely mapping using a Total Station (TS) tool. The purpose of this study is to map the UNDIKSHA campus environment in Jinengdalem Village with the resulting output in the form of a situation map and to find out how the process of making a new bm uses RTK. The method in this study is the data collection carried out in this study, namely by making direct measurements in the field using a TS tool with a closed polygon terrestrial measurement method. The results of this study are in the form of a map of the environmental situation, a topographic map, and the results of the accuracy calculation correction

Abstract

Seeing the many rice fields in Buleleng Regency. The total area of rice fields is not accompanied by the availability of data on irrigation conditions so that it becomes one of the obstacles. In addition, the average person uses the on screen method more often. this method turns out to be less accurate with conditions in the field, in contrast to the field survey method using GPS, the data obtained from the results of the field survey will be quite accurate, because we immediately go into the field and then it will be clear what the condition of the research object is. The method used is a qualitative descriptive method which analyzes the data in real terms. The results of the research obtained are the knowledge of irrigation networks in the Tukad Saba area. The real condition of the Tukad Saba irrigation area is 43.6% in a lightly damaged condition, 28.2% in a moderately damaged condition, 28.2% in a good condition, and 0% in severe damage from 39 condition points taken during the survey. field

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

The Baturiti District is a district that often experiences flash floods, causing vulnerability in the affected areas. The vulnerability caused by these flash floods includes social vulnerability, physical vulnerability, economic vulnerability, and environmental vulnerability. Therefore, there is a need to project the vulnerability to flash floods in order to minimize the impact in the coming years. This research aims to determine the extent and location of potential flash flood vulnerability in the Baturiti District in the year 2045. The method used in this research is Multi Criteria Decision Analysis (MCDA) according to Regulation No. 2 of 2012 by the National Disaster Management Agency (BNPB). Each parameter is given its respective weight and will be classified using fuzzy logic approach, and for projection, arithmetic growth method and forecast method are used. The results of this research show that the projection of flash flood vulnerability in the Baturiti District in the year 2045 covers an area of 966 hectares. The location with the highest vulnerability area is in the villages of Angseri, Candikuning, Bangli, and Baturiti.
