ANALISA KETIDAKPASTIAN PENGUJIAN RESISTANCE MODEL KAPAL LCT 1000 DWT
Main Article Content
Abstract
Uji tahanan yang dilakukan di tangki tarik memiliki kesalahan (ketidakpastian) pada hasil. Analisa ketidakpastian dapat digunakan untuk mengevaluasi kualitas data percobaan dan menyediakan perkiraan kuantitatif kesalahan percobaan. Metodologi analisa ketidakpastian, prosedur, dan hasil disajikan untuk uji tahanan model kapal LCT 1000 DWT skala > 15 dengan ukuran model kapal L = 3,997 M, B = 1000 M, T = 0,167 M, WSA = 4,089 M2, Prosedur dirangkum dan mengikuti International Towing Tank Conference (ITTC) Kualitas Manual Prosedur. Hasil penelitian menunjukkan nilai ketidakpastian sebesar 1,27% dari kecepatan 1,3271 m/s dan nilai ketidakpastian sebesar 4,79% dari tahanan 1,2771 kg.
