Abstract

Perkembangan teknologisaat inimengarah ke otomasi dan digitalisasi pada industri manufaktur salah satunya industri perkapalan. Pada industri perkapalan telahbanyak alat –alat digital yang membantu mempercepat proses pembangunan kapal. Namun masih ada beberapa tahapan yang masih dilakukan dengan cara konvensional salah satunya inclining test. Inclining test merupakan salah satu prosedur/tahapan yang dilalui dalam produksi kapal. Inclining dilakukan untuk mendapat titik berat dari suatu kapal dengan muatan kosong. Dalam praktiknya inclining test masih banyak yang menggunakan alat sederhana yaitu pendulum. Pendulum digunakan untuk mendapatkan simpangan sudutpada tiap-tiap skema pembebanan.Namun kekurangan dari penggunaan pendulum ini munculnya human error dimana penglihatan manusia bisa berbeda-beda tergantung orang yang melihat dalam pembacaan simpangan bandul. Penelitian ini diawali dengan merancang alat digital yang dapat memudahkan serta menyatukan perspektif dalam pelaksanaan inclining test. Penelitian ini bertujuan untuk mengetahui hasil inclining test denganpendekatan numerik,pendulum, alat digital. Selanjutnya dilakukan analisa dengan metode pendekatan numerik, pendulum, alat digital dan.Dari hasil penelitian ini, didapatkan rata-rata simpangan sudut denganpendekatan numerik, pendulum, dan alat digitalmasing-masing 4,648°;4,641° ; 4,639°.Adapun untuk perbandingan rata-rata simpangan sudut antarapendulum dan alat digital ditemukan error sebesar 0,05%.. Sementara itu perbedaan antara alat digital dan pendekatan numerik sebesar 0,19%. Error tersebut masih berada dalam kriteria error yang diizinkan berdasarkan ketentuan yang ditetapkan oleh DNV-GL.Untuk hasil nilai KG berdasarkan hasil perhitungan setelah eksperimen pendulum dan alat digital masing-masing bernilai 0,042899 m dan 0,04297 m.

Current technological developments lead to automation and digitization in the manufacturing industry, one of which is the shipping industry. In the shipping industry, there are many digital tools that help speed up the shipbuilding process. However, there are still several stages that are still carried out in a conventional way, one of which is the inclining test. Inclining test is one of the procedures/steps that are passed in ship production. Inclining is done to get the center of gravity of a ship with an empty load. In practice, many inclining tests still use a simple tool, namely a pendulum. The pendulum is used to obtain the angular deviation in each loading scheme. However, the drawback of using a pendulum is the emergence of human error where human vision can vary depending on the person who sees the reading of the pendulum deviation. This research begins with designing a digital tool that can facilitate and unify perspectives in the implementation of the inclining test. This study aims to determine the results of the inclining test with a numerical approach, a pendulum, a digital tool. Furthermore, the analysis is carried out using a numerical approach, pendulum, digital tools and. From the results of this study, the average deviation of the angles using a numerical approach, a pendulum, and a digital device is 4.648°; 4.641°; 4.639°. As for the comparison of the average deviation of the angle between the pendulum and the digitaldevice, an error of 0.05% was found. Meanwhile, the difference between the digital instrument and the numerical approach was 0.19%. The error is still within the allowed error criteria based on the conditions set by DNV-GL. For the results of the KG values based on the results of calculations after the pendulum experiment and digital tools, the values are 0.042899 m and 0.04297 m, respectively.
