Abstract

Dalam bidang kekuatan konstruksi kapal, perlu memperhitungkan kekuatan memanjang dan melintang suatu konstruksi kapal. Pada saat ini terdapat teknologi strain gauge, strain gauge adalah komponen elektronika yang dipakai untuk mengukur regangan (deformasi atau strain) secara realtime. Penelitian ini perlu dilakukan untuk menentukan nilai tegangan pada saat kondisi beban gelombang dan air tenang. Model tongkang dibuat dengan ukuran panjang 120 cm, lebar 30,5 cm, dan tinggi 8,3 cm. Untuk mendapatkan nilai tegangan pada model tongkang dilakukan 2 metode pendekatan yaitu metode elemen hingga dan eksperimen. Perhitungan metode elemen hingga dilakukan dengan bantuan aplikasi finite element analysis, sebelum melakukan proses running harus dilakukan konvergensi, dari hasil konvergensi tersebut didapatkan ukuran titik uji sebesar10 mm. Proses pendekatan eksperimen ini dilakukan dengan bantuan sesnsor strain gauge sebagai pengukur regangan, dari nilai regangan tersebut kemudian dikonversikan menjadi tegangan, dimana hasil nilai tegangan tersebut dilakukan validasi terhadap nilai tegangan yang didapatkan dari perhitungan metode elemen hingga. Dari penelitian ini didapatkan hasil bahwa pada kondisi air tenang tegangan tertinggi terjadi pada daerah 30 cm didepan buritan kapal dengan tegangan sebesar 0,207 MPa pada muatan kosong dan 0,774 MPa pada saat muatan penuh.

In the ship construction strength, it is necessary to account for the longitudinal and transverse strength of a ship construction. At this time there is a strain gauge technology, a strain gauge is an electronic component that is used to measure pressure (deformation or strain) in real-time. Therefore, it is necessary to conduct research on the use of strain gauges for ships in sailing conditions. This study was conducted to determine the value of stress during wave and calm water conditions, The barge model is made with a length of 120 cm, a width of 30.5 cm, and a height of 8.3 cm with a full load. To get the stress value on the barge model, two approaches were used, namely the numerical method and the experimental method. Numerical calculations are carried out with the finite element analysis application, where before carrying out the running process, convergence must be carried out, from the results of the convergence the test point size is 10 mm. The process of this experimental approach is carried out with strain gauge sensor as strain measurement, from the strain value it is then converted into stress, where the results of the stress value are validated toward the stress value obtained from numerical calculations. This study found that in calm water conditions, the highest stress occurred in an area of 30 cm in front of the stern with stress of 0,207 MPa on an empty load and 0,774 MPa on a full load.
