Abstract

Tekstur tanah dapat digunakan untuk mengetahui klasifikasi sebaran tekstur tanah maupun kesesuaian tekstur tanah berdasarkan tutupan lahan, tekstur tanah merupakan tingkat kehalusan tanah yang dilihat dari partikel-partikel yang terdapat pada suatu tanah. Penelitian ini bertujuan untuk mengetahui pola sebaran tekstur tanah serta pola sebaran tutupan lahan berdasarkan tekstur tanah di Kabupaten Bangli. Metode yang digunakan dalam penelitian ini yaitu empirik kualitatif diamana metode ini dilakukan dengan pengambilan sampel tanah secara acak pada wilayah penelitian serta pengujian sampel ini agar menghasilkan tekstur tanah dilakukan pengujian di laboratorium hasil uji sampel tanah diberikan pengkelasan tekstur tanah berdasarkan diagram segitiga tekstur tanah sehingga menghasilkan sebuah peta kondisi tekstur tanah di Kabupaten Bangli serta dibentuk pula dalam diagram tabel yang menunjukan bahwa hasil sebaran kondisi tekstur tanah di Kabupaten Bangli paling dominan berada pada tekstur tanah geluh pasir seluas 12920.05 ha yang tersebar di 3 Kecamatan yaitu Bangli, Kintamani dan Susut namun Kecamatan Kintamani memiliki luasan terbesar seluas 11452.40 ha serta memiliki sebaran tutupan lahan dengan luasan terbesar terdapat pada tutupan lahan kebun campuran dan tegalan atau ladang.

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

East Sumba Regency faces challenges to food security due to geographical conditions, a dry climate, and socio-economic dynamics. This study aims to analyze the changes in food availability and demand between 2023 and 2029. A descriptive quantitative approach was employed, utilizing data on food production, population, and regional characteristics. The results show that although a food surplus existed in 2023, it is projected to decline by 2029 due to land degradation, climate change, population growth, and land-use change. Geographical factors such as topography, soil type, and water distribution significantly influence food production. In conclusion, strategies including the protection of productive land, the strengthening of irrigation systems, crop diversification, and the adoption of adaptive technologies are essential to enhance food security in the future.
