Abstract

Characterization of Oil Palm Trunks (OPT) in height rod different OPT that compregnated with polystyrene resin modifications have been done, polystyrene resins modified with acrylic acid and benzoyl peroxide incorporated into the OPT pore size 15x2x2 cm3 shaped beam that is placed in the compregnator has been modified with -5 atm pressure for 15 minutes. Based on the tensile tests conducted showed that the optimum mechanical properties of the OPT on the bottom of the stem height. with the addition of 20% resin. Similarly, the thermal properties OPT marked increases with increasing temperature degradation of OPT compregnated modified polystyrene resin at a concentration of 20%. From the above two tests showed that OPT improved quality of prior treatment compregnation, analysis of thermal degradation by using Thermogravimetry

Abstract

Batang Kayu Kelapa Sawit (KKS) yang tersedia secara te!s menerusdan mencemari Ungkurtgan perkebunan belum dimanfaaikan secara ekonomiskarena kualitasnya yang masih rendah. sehingga tidak dapat dipergunakan sebagai kayu pertukangan. Dalam hal lain, polistirena yang bersifat hidrofobik dapai dimodifikasi dengan menggunakan bahan pemodifikasi untuk menghasilkan resin yang dapai berinteraksi dengan bahan kayu. Sehubungan tingginya permintaan  bahan kayu di· Indonesia, KKS dapat digunakan sebagai salah satu alternative  pengolahan kayu untuk berbagai keperluan. Dalam penelitian ini KKS diolah menggunakan Teknik Impregnasi dengan resin polisterena termodifikasi pada kondisi optimum operasi pada tekanan 1 atm dan waktu impregnai 9 jam. Hasil impregnasi menunjukkan harga modulus patah (MoR) dan modulus elastisitas (MoE) KKS hasil impregnasi meningkat dari 117 Kg/Cm menjadi 691,2 Kg/Cm sehingga kualitas KKS bertambah baik berdasarkan Standar Nasional (SNI,1994). Data analisis termal serta uji kekuatan tarik dan lentur menunjukkan resin polistirena termodifikasi dapat meningkatkan sifat mekanik dan fisik dari KKS.
