SIFAT FISIS DAN MEKANIK KOMPOSIT POLIMER DARI LIMBAH STYROFOAM, ASPAL,
SERAT PINANG DAN PASIR HITAM
ABSTRAK
Telah dilakukan penelitian tentang pembuatan dan karakterisasi genteng komposit polimer menggunakan campuran pasir hitam, aspal, serat pinang, styrofoam dan poliester. Penelitian ini bertujuan untuk mengetahui pengaruh variasi komposisi terhadap karakteristik genteng. Komposisi poliester, aspal, styrofoam yang digunakan tetap, yaitu 29%, 5% dan 1% dari berat total sampel 100%, sedangkan komposisi pasir hitam dan serat pinang divariasikan dengan perbandingan; (65% : 0%), (64% : 1%), (63% : 2%) dan (62% : 3%). Karakterisasi yang dilakukan meliputi pengujian densitas, porositas, daya serap air, uji kekuatan lentur dan uji impak. Hasil penelitian menunjukkan karakteristik genteng sangat dipengaruhi oleh fraksi berat serat. Karakteristik optimum dicapai pada komposisi
(29:5:1:64:1)%, dan diperoleh kerapatan 2,54 gr/cm3, porositas 12,36%, daya
serap air 5,24%, kekuatan lentur 11,594 MPa, kekuatan impak 4985,9 J/m2.

CHARACTERISTIC PHYSIC AND MECANIC POLYMER COMPOSITES OF STYROFOAM WASTE, ASPHALT, NUT FIBER AND BLACK SAND
ABSTRACT
The research on the manufacture and characterization of polymer composite tile using a mixture of black sand, asphalt, nut fiber, styrofoam waste and polyester has been done. This reset aims to determine the effect of variations in composition the characteristics of the tile roofed. The composition of polyester, asphalt, styrofoam is made constant, of 29%, 5% and 1% of the total weight of the sample 100%, while the composition of black sand and nut fiber varied by comparison; (65% : 0%), (64% : 1%), (63% : 2%) and (62% : 3%). Characterization testing performed included density, porosity, water absorption, flexural test and impact test. The results show that the characteristics of the tile is strongly influenced by the weight fraction of fiber. The optimum characteristics are achieved in the
composition (29:5:1:64:1)%, and obtained 2,54 gr/cm3density, porisity 12,36%, water absorption 5,24%, flexural strength of 11,594 MPa, impact strength of
4985,9 J/m2.
