• W2912087393 abstract "Selat Lepar merupakan perairan dengan batas antara kawasan pesisir Sadai dengan kawasan Pulau Lepar Kabupaten Bangka Selatan. Informasi perairan kedalaman (batimetri) merupakan salah satu hal penting dalam menentukan wilayah alur jalannya pelayaran dalam perencanaan kawasan industri Sadai. Penelitian ini bertujuan untuk menganalisis data batimetri lapangan dan citra Satelit Landsat 8 dan membuat dalam bentuk peta 3D di perairan Selat Lepar Kabupaten Bangka Selatan. Penelitian ini dilaksanakan pada bulan Oktober hingga April di perairan Selat Lepar Kabupaten Bangka Selatan. Metode yang telah digunakan adalah metode akustik dengan melakukan pengambilan data batimetri di lapangan menggunakan singlebeam echosounder kemudian data lapangan dibandingkan dengan metode pengolahan citra landsat 8 menggunakan algoritma Satellite Derived Bathymetry (SDB). Algoritma Satellite Derived Bathymetry (SDB) menggunakan tiga pendekatan yaitu rationing, thresholding dan mean value Kanal 5 dan Kanal 2 citra satelit Landsat 8. Pengukuran lapangan nilai batimetri perairan Selat Lepar Kabupaten Bangka Selatan berkisar antara 0.8 – 19 m. Model pendekatan thresholding memiliki hubungan yang paling baik dengan persamaan regresi polinomial y = -235,3(B2-B5)2 + 126,2(B2-B5) - 13.35 dan y = -235,3(B5-B2)2 – 126,2(B5-B2) – 13,35, nilai koefisien determinasi tertinggi R2= 0,849. Peta layout batimetri perairan Selat Lepar Kabupaten Bangka Selatan dalam bentuk 3D menghasilkan kedalaman 0-19 m dengan bentuk dasar perairan dangkal, landai dan dangkal. Lepar Strait is a borderline area between Sadai coastal area with Lepar Island area of South Bangka Regency. Basic information of bathymetry is one of important things in determining the area of the shipping path in the planning of the Sadai industrial estate. This study aims to analyze the bathymetry and Landsat 8 satellite data and create it in 3D map form in the Lepar Strait area of South Bangka Regency. This research was conducted from October to April in Lepar Strait waters in South Bangka Regency. The method that has been used is acoustic method by collecting data using singlebeam echosounder and data then proceed with the method of image processing of landsat 8 using Satellite Derived Bathymetry (SDB) algorithm. The Satellite Algorithm Derived Bathymetry (SDB) used three approaches namely rationing, thresholding and the mean value of Kanal 5 and Kanal 2 Landsat 8 satellite. The measurement of bathymetry Lepar Strait of South Bangka Regency between 0.8 to 16 m. The thresholding approach model has the best relation with the polynomial regression equation y = -235.3(B2-B5)2 + 126.2 (B2-B5) - 13.35 and y = -235.3 (B5-B2) 2 - 126.2 (B5-B2) –13.35, coefficient value of determination main R2 = 0.849. Map of bathymetry layers Lepar Strait of South Bangka Regency in the form of 3D produces a depth of 0-19 m with a shallow, slope and shallow base." @default.
