Abstract
Kapal Ikan Fibreglass Reinforced Plastic (FRP) yang dibangun pemerintah melalui program Direktorat Jenderal Perikanan Tangkap (DJTP) pada tahun 2017 untuk menunjang sektor perikanan di Indonesia adalah sebesar 1.068 unit dengan beragam ukuran. Beberapa kapal ikan FRP yang dibangun galangan telah menggunakan core material sebagai bahan konstruksi sandwich. Namun, harga core material yang digunakan memiliki harga yang cukup mahal. Maka dalam penilitian ini dilakukan alternatif penggunaan core material kayu Waru dan bilah Bambu sebagai bahan konstruksi sandwich lambung kapal ikan Fiberglass Reinforced Plastic (FRP). Untuk mengetahui apakah core material penyusun memenuhi dengan standar yang disyaratkan oleh Biro Klasifikasi Indonesi (BKI) maka perlu dilakukan pengujian spesimen yang meliputi tensile test dan bending test dengan beberapa variasi ketebalan core material. Hasil dari pengujian beberapa variasi ketebalan core material penyusun FRP dianalisa secara teknis untuk memperoleh nilai tensile strength, modulus of rupture (MoR), modulus of tensile elasticity dan modulus of bending elasticity. Variasi penggunaan core material bilah Bambu memenuhi kriteria sifat mekanik yang disyaratkan oleh BKI dengan nilai tensile strength rata-rata 118.98 MPa, modulus of rupture (MoR) rata-rata 216.63 MPa, MOE tarik rata-rata 8.46 GPa dan MOE tekuk rata-rata 8.76 GPa. Sedangkan variasi penggunaan core material kayu Waru tidak memenuhi kriteria sifat mekanik yang disyaratkan oleh BKI dengan nilai tensile strength rata-rata 82.03 MPa, modulus of rupture (MoR) rata-rata 141.07 MPa, MOE tarik rata-rata 4.76 GPa dan MOE tekuk rata-rata 3.28 GPa Kemudian variasi laminasi sandwich ini digunakan sebagai dasar perhitungan biaya material sehingga didapatkan korelasi sifat mekanik dengan harga pokok pembanguna kapal ikan FRP 10 GT dengan konstruksi sandwich. Biaya pembangunan kapal ikan FRP 10 GT yang paling ekonomis pada penelitian ini adalah variasi yang menggunakan core material bilah Bambu dengan biaya total sebesar Rp120.427.230 lebih murah 16.17 % dari biaya core material PVC. Sedangkan variasi yang menggunakan core material kayu Waru memimiliki biaya total sebesar Rp130.153.650 lebih murah 9.40 % dari biaya core material PVC.

1,068 units of various sized fiberglass reinforced plastic (FRP) vessels built by the government through the program of the Direktorat Jenderal Perikanan Tangkap (DJTP) in 2017 to support the fisheries sector in Indonesia. Some FRP fishing vessels built by the shipyard have used core materials as sandwich construction materials. However, the price of the core material used has a fairly expensive price. So in this research Waru wood core material and bamboo blades is used as construction materials alternatives for Fiberglass Reinforced Plastic (FRP) fishing vessels. To find out whether the core material complies with the standards required by the Indonesian Classification Bureau (BKI), it is necessary to test the specimens. This test includes the tensile test and bending test with several variations in the thickness of the core material. The results of testing several variations of the thickness of core FRP materials were analyzed technically to obtain tensile strength, modulus of rupture (MoR), modulus of tensile elasticity and modulus of bending elasticity values. Variations that use core bamboo blade material meet the criteria for mechanical properties required by BKI with an average tensile strength value of 118.98 MPa, an average modulus of rupture (MoR) of 216.63 MPa, an average modulus of tensile elasticity of 8.46 GPa and an average modulus of bending elasticity of 8.76 GPa. While variations with Waru wood as core material do not meet the criteria of mechanical properties required by BKI with an average tensile strength value of 82.03 MPa, average modulus of rupture (MoR) of 141.07 MPa, modulus of tensile elasticity averaged 4.76 GPa and modulus of bending elasticity averaged 3.28 GPa. Then these sandwich lamination variations are used as a basis for calculating material costs, so that the correlation of mechanical properties with the cost of building the FRP 10 GT fish boat with sandwich construction is obtained. The most economical cost of building the FRP 10 GT fish boat in this research is the variation that uses bamboo blade core material with a total cost of Rp120.427.230 , 16.17 % cheaper than the core cost of PVC material. Whereas variations using Waru wood core material have a total cost of Rp130.153.650 , 9.40 % cheaper than the core cost of PVC material.
