Studi Uji Mekanik Material Komposit Batang Kelapa Sawit (Elaeis Guineensis Jacq)

Abstract

The need for building construction materials such as lightweight brick walls that are strong, environmentally friendly and inexpensive is the dream of every construction worker. This study aims to obtain the compressive and flexural strength values of the composite material of oil palm trunk fiber (elaeis guineensis jacq). The manufacture of this composite material uses a fiber-matrix ratio of 30:70 (%) with 2 (two) variations, namely 25:15:20:10 and 25:15:25:5 (%). The matrix consists of PCC cement, white cement, tapioca adhesive, PVAc adhesive and water. The specimens were made cylindrical with a diameter of 100x200 mm in a number of 10 specimens according to SNI 1974: 2011 standards. From the tests carried out, the highest compressive strength value was 6.87 MPa. For the bending test, 10 specimens were tested according to the ASTM D143-94 standard. The value of the modulus of elasticity (MOE) is 5.088 MPa and the modulus of rupture (MOR) is 4.056 MPa. It can be concluded that the composite material of oil palm trunks can be used as decoration and building construction materials
