Abstract

Telah dilakukan penelitian tentang penentuan jenis distribusi probabilitas dan intensitas curah hujan di Pulau Kalimantan. Tujuan penelitian ini adalah menentukan jenis distribusi probabilitas dan intensitas curah hujan di Pulau Kalimantan. Data yang digunakan adalah data curah hujan harian maksimum di Pulau Kalimantan periode tahun 1992-2021 pada 5 stasiun yaitu Stasiun Meteorologi Supadio, Stasiun Meteorologi Beringin, Stasiun Meteorologi Temindung, Stasiun Meteorologi Gusti Syamsir Alam, dan Stasiun Meteorologi Juwata. Penelitian ini menggunakan metode Mononobe untuk menghitung intensitas curah hujan dan penggambaran kurva Intensity Duration Frequency (IDF). Hasil penelitian ini menunjukkan jenis distribusi probabilitas yang sesuai dengan data curah hujan pada 5 stasiun yang ada di Pulau Kalimantan yaitu log pearson type III. Hasil kurva IDF menunjukkan bahwa intensitas tinggi terjadi pada durasi 5 menit dan selalu meningkat dari kala ulang 2 tahunan hingga 100 tahunan serta hujan deras berlangsung dalam waktu yang singkat, namun tidak deras berlangsung dalam waktu yang lama.

Abstract

This study aims to analyze the statistical parameters of bed load grains in Sungai Kakap Waters, Kubu Raya Regency, West Kalimantan Province. Bed load sampling was carried out at seven stations, with five sampling points each. The hydrometer test on the sample was carried out to determine the grain type and size of the bed load, and statistical parameter analysis to determine the mean size, sorting, skewness, and kurtosis. The results showed that the fraction of bed load in the form of sand was 38.54%, silt was 42.11%, and clay was 19.28%. The bed load was dominated by three types namely clay loam, loam, and silt loam. Based on the grain size parameters of the bed load, the mean size (in φ units) is 0.94 – 2.24, with the classification of coarse sand to fine sand. The results also showed that the sorting obtained is poorly sorted, the skewness of the sediment is very fine skewed, and the kurtosis is platykurtic.Keywords: bed load; sorting; skewness; kurtosis
