Abstract

Dalam penelitian dan pengembangan fasilitas pangkalan kapal selam TNI AL  diperlukan sarana prasarana sandar yang dapat mudah dalam penempatan dan  pergeseran guna mendukung kebutuhan pertahanan seluruh wilayah perairan Indonesia dengan kekuatan Koarmada Laut.  Kapal Selam yang dioperasikan oleh TNI AL merupakan bagian dari 7 program Alpalhankam di Kementrian pertahanan, memerlukan pengembangan teknologi pertahanan yang dibutuhkan untuk mendukung operasional sandar kapal selam. Fasilitas sandar dibutuhkan kapal selam dan sebagai fasilitas pengaman peralatan dan sistem akomodasi pada saat beroperasi di seluruh wilayah perairan Indonesia. Pada konsep desain dermaga ponton sandar kapal selam berbasis Modular Approach berbahan High Density Polyetylene untuk mendukung pangkalan operasional wilayah Indonesia, maka diperlukannya  analisis pengujian kekuatan struktur ponton dengan Finit Element Method (FEM) tahapannya analisis dan pengujian mengunakan Software pada kekuatan struktur dan stabilitas dengan pendekatan Software AutoCAD, Autudesk Inventor dan Maxsurf. Dari perhitungan gaya gaya yang bekerja pada ponton sebesar 615 kN didapat analisis tegangan/ regangan untuk stress maksimal yang dapat diterima oleh material yang digunakan sebesar Yield Strength sebesar 207 MPa, dimana hasil untuk static stress pada gaya bentur 162.715 MPa (faktor keamanan 1.27652) dan gaya tarik 85,0034 MPa (faktor keamanan 2.49957) masih kondisi aman tidak melewati nilai stress maximal material. Sedangkan analisis stabilitas dan periode oleng dilakukan pada 3 kondisi diperoleh kondisi yang stabil dan momen balik relatif cepat kembali posisi tegak, dengan periode oleng terendah pada loadcase 1  dengan T sebesar 3,8264 detik, dengan demikian analisis yang dilakukan masih memenuhi syarat yang aman pada ponton sandar kapal selam berbasis Modular Approach berbahan High Density Polyethylene
