Abstract
This study aims to analyze the absorption of sea water on Composite Materials palm frond fibers per 24 hours for 9 days and analyze the effect of immersion for 3, 6, and 9 days of the tensile strength fiber-reinforced composite material of palm fronds. The polymers used type of epoxy resin. Palm frond fibers arranged randomly, then fiber treated alkali 5% for 2 hours, and then molded with a size of 200 x 200x 5 mm with a ratio between matrix and fiber is 90:10 to press molding tool. Composite plates immersed in a container filled with sea water aquarium for 3, 6, and 9 days and every 24 hours of material in weigh, test procedures seawater absorption refers to the ASTM D 570 - 98. As well as every 3, 6, and 9 days plate removed and cut into a polymer composite beam according to the standard ASTM D638-02 (type 1). Each variable will be tested for 3 times. Based on the test results get soaking in the absorption rate reached its peak in the first day, namely 0.26% for the first specimen testing three-day, 0.5% for the second specimen testing 6 days and 0.25% for the third specimen testing nine days. Then it will go on steadily and decreases until it reaches saturation point. Where for the first specimen in the third day of absorption of 0.49%, a second specimen in the sixth day of absorption of 1.71%, and the third specimen in the esembilan absorption 0.93%. And the influence of sea water immersion tensile strength fiber Composite palm fronds have a dynamic effect on the test results before immersion up to 9 days of immersion that is power up and down. With a value of 15.468 MPa before immersion, 17.046 MPa 3 days of immersion, 15.107 MPa 6 day immersion, and 21.137 MPa 9 days of immersion.

Summary
Indonesia adalah negara kepulauan terbesar di dunia, menurut data Departemen Dalam Negeri Republik Indonesia tahun 2004, Indonesia memiliki sebanyak 17.504 buah pulau dan 7.870 di antaranya telah mempunyai nama, sedangkan 9.634 belum memiliki nama. Sejalan dengan banyaknya jumlah nelayan tangkap indonesia sehingga banyak pula jumlah kapal yang di butuhkan untuk digunakan dalam penangkapan ikan, menurut data dari Badan Pusat Statistik Indonesia (BPS) pada tahun 2010 jumlah kapal/perahu penagkap ikan mencapai 742,369 buah perahu/kapal. Sampai saat ini sarana yang digunakan di laut masih sangat tergantung dari bahan baku kayu Namun kekuatan kayu dipengaruhi salah satunya oleh kadar air yang dikandung kayu tersebut. Tujuan yang hendak dicapai dalam penelitian ini yaitu menganalisa daya penyerapan air laut pada Material Komposit serat pelepah sawit per 24 jam selama 9 hari dan menganalisis pengaruh perendaman selama 3, 6, dan 9 hari terhadap kekuatan tarik material komposit diperkuat serat pelepah sawit
