Abstract
Unsaturated Polyester Resin merupakan polimer termoset yang sering digunakan sebagai matriks komposit kapal karena keunggulan biaya yang murah dan tahan terhadap korosi. Namun pembuatannya menggunakan minyak bumi yang tidak ramah lingkungan dan tidak biodegradable dibandingkan bioresin. Bioresin adalah resin atau formulasi resin yang berasal dari sumber biologi. Salah satu sumber yang sering digunakan adalah minyak nabati yang mudah didapat dan ramah lingkungan. Dalam penelitian ini dilakukan pencampuran resin dengan minyak nabati dengan variabel minyak sawit, minyak kelapa, minyak kedelai, minyak wijen, dan minyak jagung sebagai laminating resin yang sesuai aplikasi lambung kapal yang ramah lingkungan. Pengujian yang telah dilakukan meliputi uji SEM, uji FTIR, uji TGA, uji densitas, uji absorbsi air, uji bending, dan uji tensile. Dari pengujian yang telah dilakukan,data yang didapatkan sifat mekanik rata-rata dari hasil uji Tarik dengan hasil tertinggi campuran resin dengan minyak kedelai yaitu 22.63 MPa, elongation dengan hasil tertinggi campuran resin dengan minyak jagung yaitu 28%, dan flexural strength dengan hasil tertinggi campuran resin dengan minyak kedelai yaitu 7.73 MPa. Secara morfologi juga terdapat perbedaan diantara pencampuran resin dengan minyak nabati dan unsur dominan karbon serta oksigen dengan perbedaan persentase setiap jenis pencampuran minyak nabati. Namun campuran unsaturated polyester dengan minyak nabati belum dapat diaplikasikan untuk laminating resin lambung kapal standar Biro Klasifikasi Indonesia karena belum memenuhi standar minimum.

Unsaturated Polyester Resin is a thermosetting polymer generally used as matrix of composite in ship because of advantage in cheap price and corrosion resistant. But in its manufacture uses petroleum which is not environtmentally friendly and it’s not biodegradable comparing with bioresin. Bioresin is resin or resin formulation which is derived from biological resource. One of resource often used is vegetable oil which is easy to get and environtmental friendly. In this research mixing resin to be carried out with vegetable oil with variable palm oil, coconut oil, soybean oil, sesame oil, and corn oil as laminating resin that suitable with encirontmentally friendly hull application. Tests that have been carried out include SEM test, FTIR test, TGA test, density test, water absorption test, bending test, and tensile test. From the tests that have been done, the data obtained by the average mechanical properties of the tensile test results with the highest yield of resin mixture with soybean oil which is 22.63 MPa, the highest elongation with resin mixture with corn oil which is 28%, and the highest yield mixed flexural strength resin with soybean oil which is 7.73 MPa. Morphologically there is also a difference between mixing resin with vegetable oil and the dominant elements of carbon and oxygen with a difference in the percentage of each type of mixing of vegetable oils. However, the mixture of unsaturated polyester with vegetable oil has not been applied for laminating the standard hull resin of the Biro Klasifikasi Indonesia because it has not met minimum standards.
