Abstract
Revolusi industri 4.0 telah menghasilkan banyak peningkatan yang signifikan pada perkembangan teknologi. Perkembangan teknologi tersebut juga berpengaruh di dunia perkapalan, sehingga memungkinkan untuk dilakukannya monitoring struktur pada kapal secara real time. Dalam bidang kekuatan konstruksi kapal, perlu diperhitungkan kekuatan memanjang dan melintang suatu konstruksi pada kapal. Saat ini, terdapat teknologi yang bernama strain gauge, strain gauge adalah sebuah alat atau komponen elektronika yang dipakai untuk mengukur tekanan (deformasi atau strain) secara real time. Oleh karena itu, perlu dilakukan penelitian pada penggunaan strain gauge untuk kapal dengan berbagai kondisi kapal, salah satunya adalah akibat sobekan lambung atau crack. Penelitian ini dilakukan untuk menentukan nilai tegangan pada saat kondisi crack, dimana model kapal yang digunakan adalah kapal jenis barge yang telah dilakukan skala 1:100 dari ukuran barge asli, kemudian dihasillkan ukuran utama model barge dengan panjang 120 cm, lebar 30 cm, dan tinggi 8,4 cm. Untuk mendapatkan nilai tegangan pada model barge dilakukan 2 metode pendekatan yaitu metode numerik dan eksperimen. Perhitungan numerik dilakukan dengan bantuan aplikasi finite element analysis yaitu ABAQUS. Sedangkan proses pendekatan eksperimen ini dilakukan dengan bantuan sensor 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 numerik. Dari penelitian ini didapatkan hasil bahwa pada kondisi air tenang tegangan tertinggi terjadi pada crack sebesar 1,5 cm di bagian lambung kapal dengan tegangan sebesar 1,672 MPa pada muatan kosong dan 2,349 MPa pada saat kondisi bermuatan.

Industrial revolution 4.0 has already shows significant increase in technological developments. These technological developments can be applied in the marine industries, making it possible to monitor structures on ships in real time. In the field of ship construction strength, it is necessary to take into account the longitudinal and transverse strength of a construction on the ship. Currently, there is a technology named strain gauge. A strain gauge is a tool that has 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 stress value when the hull is damaged or cracked, where the ship model used is a barge type ship that has been scaled 1:100 from the original barge size, then the main size of the barge model is produced with a length of 120 cm, a width of 30 cm, and 8.4 cm high. To get the stress value on the barge model, two approaches were used, the numerical method and the experimental method. Numerical calculations are carried out with the help of the finite element analysis application. While the process of this experimental approach is carried out with the help of a strain gauge sensor as a strain gauge, the strain value is then converted into stress, where the results of the stress value are validated against the stress value obtained from numerical calculations. From this study, it was found that in calm water conditions the highest stress occurred at the crack of 1,5 cm in the hull with a stress of 1,672 MPa on an empty load condition and 2,349 MPa with full load condition
