Abstract

Seiring dengan berkembangnya zaman dan teknologi, penambahan sistem peralatan pada kapal selam merupakan hal yang umum terjadi. Penambahan peralatan dengan ukuran relatif besar akan mengubah letak center of gravity, massa total, dan momen inersia kapal selam. Dengan adanya perubahan tersebut, karakteristik maneuvering dari kapal selam pada gerakan diving juga akan terpengaruh. Penelitian ini bertujuan untuk mendapatkan hasil perancangan program manuvering, hasil manuvering diving kapal selam setelah dilakukan penambahan peralatan, serta hasil tersebut juga akan dibandingkan dengan kondisi sebelum ditambahkan peralatan. Penelitian ini juga akan memberikan rekomendasi pengkondisian ballast agar penambahan peralatan baru berdampak insignifikan terhadap manuvering diving kapal selam. Simulasi dilakukan dengan membuat program diving manuvering kapal selam yang terdiri dari persamaan model state-space kapal selam 3 DOF (surge, heave, dan pitch), input hydroplane, dan LQR controller pada software MATLAB. Program tersebut juga digunakan untuk mendapatkan hasil simulasi diving kapal selam setelah dilakukan modifikasi penambahan massa peralatan sebesar 1.912 ton pada 39.82 meter dari titik AP. Dengan penambahan tersebut, letak center of gravity dan momen inersia pitching mengalami kenaikan sebesar 0.03% sehingga peak time mengalami penurunan sebesar 0.78% dari 89.3 s menjadi 88.6 s, dan delay time mengalamai kenaikan sebesar 0.23% dari 44.3 s menjadi 44.4 s. Untuk mengatasi perubahan beberapa parameter tersebut, pengkondisian ballast dilakukan dengan menghilangkan dry ballast pada post 19 dan 20 (40.84 meter dari titik AP) dengan total berat 1944 kg. Dengan penghilangan dry ballast tersebut, perubahan nilai center of gravity, momen inersia pitching, delay time, dan peak time dapat diminimalisasi sehingga berdampak insignifikan terhadap manuvering diving kapal selam.

As advancement of technology, the addition of equipment systems on submarines is a common occurrence. The addition of equipment alters the position of the center of gravity, total mass, and moment of inertia of the submarine. These changes also affect the maneuvering characteristics of the submarine during diving. This study aims to obtain manoeuvring diving program, the diving maneuvering results of a submarine after the addition of equipment, and these results will be compared with the conditions before the equipment was added. The research will also provide recommendations for ballast conditioning to ensure that the addition of new equipment has an insignificant impact on the diving maneuvering of the submarine. The simulation is performed by developing a submarine diving maneuver program consisting of a 3 DOF (surge, heave, and pitch) state-space model equation, hydroplane input, and LQR controller using MATLAB software. The program is also used to simulate the diving behavior of the submarine after modifying the equipment mass by 1,912 tons at a distance of 39.82 meters from the AP point. With this addition, position of the center of gravity and moment of inertia of pitching increase 0.03%, resulting in decreasing in peak time by 0.7%, from 89.3 s to 88.6 s, while delay time increases by 0.23%, from 44.3 s to 44.4 seconds. For mitigating these parameter changes, ballast conditioning is performed by removing the dry ballast at posts 19 and 20 (40.84 meters from the AP point) with a total weight of 1944 kg. By removing the dry ballast, the changes in the center of gravity, moment of inertia of pitching, delay time, and peak time can be minimized, thereby having an insignificant impact on the diving maneuvering of the submarine.
