| dc.description.abstract | This study focused on the synthesis process of wood polymer composite (WPC). The
purpose of this study is to optimize the use of cellulose microfibrils, recycle-Polyethylene
(rPE), Polyethylene-graft-Maleic Anhydride (PE-g-MA), and gamma ray irradiation on
the tensile strength and elongation values of WPC. The analysis and optimization method
used in this study is based on a mathematical model found in Design Expert Software
(DES). WPC synthesis was carried out based on a formula determined by DES. The
synthesis process includes compounding, crushing, printing, and cutting specimens based
on ASTM 1822-L. While the process of testing the value of tensile strength and elongation
is carried out based on ASTM D638 using the Universal Testing Machine (UTM). The
results of the UTM characterization data analysis showed that the use of gamma ray
irradiation can increase the interaction between the WPC materials. The results of the
analysis also showed that the tensile and elongation strength values could be affected if
there was an interaction between the cellulose microfibrils, rPE and PE-g-MA used. The
optimum formula of the synthesized WPC was in the ratio of the composition of cellulose
microfibrils: rPE: PE-g-MA (3.35 : 45.268 : 0.382) grams which was irradiated at a dose
of 35,490 kGy. The formula produces tensile and elongation strength values of 12,401
MPa and 4.36%, respectively | en_US |
