This study aimed to determine the effect of composition between sugar palm fiber ( Arenga Pinnata ) and polyester resin as composite materials. The parameters are focused on impact strength, tensile strength, and modulus of elasticity and are compared to  Badan Klasifikasi Indonesia  (BKI) standard which is Regulations for the Classification and Construction of Ship in Indonesia. The composition of fiber and resins is 30:70%, 40:60%, and 50:50% using mass fraction. The angle orientation of fiber is 0,90,0,90 and manufacturing process uses the hand lay up method. Impact testing is carried out with the ASTM D5942-96 standard and Tensile Testing is carried out with the ASTM D638-03 standard. The results showed that the composition of 50:50% is the highest test value compared to other compositions, with average impact strength of 1.703 x 10 16  kg mm −2 , tensile strength of 27.13 N mm- 2  and modulus of elasticity of 790.01 N mm −2 . Although the results of the value of the impact test, tensile test and modulus of elasticity of the composition of the mass fraction of sugar palm fiber ( Arenga Pinnata ) material are still below the BKI standard, it still has the potential to continue to be developed as an alternative raw material for making Jukung (traditional boat in Banjarmasin).
