Pengaruh Komposisi Plastik Polipropilena dan Partikel Batang Pisang Barangan terhadap Kualitas Papan Plastik

Abstract

WINDA MARTOGI SITUMEANG: Effect of Plastic Polypropylene Composition and Particle of Barangan Banana Stems Against Quality Wood Polymer Composite. Under supervised by TITO SUCIPTO and APRI HERI ISWANTO. Banana trunk is agricultural waste which is potentially as one of the solutions to be used as a material utilization berlignoselulosa products such as plastic boards. The purpose of this study was to evaluate the effect of the composition of the plastic polypropylene (PP) and banana stem particles to quality plastic board and determine the best composition for the physical and mechanical properties of plastic boards. Making plastic boards using a variation of the composition of polypropylene plastic (PP) and banana stem particles are 50:50, 60:40, 70:30 and 80:20. Mixing materials is done by using an extruder machine and compression board sheets using hot forged at a temperature of 1700C pressure of 25 kgf / cm2 for 10 minutes. The sample size of 25 cm x 25 cm x 1 cm with a target density of 0.7 g / cm3. Data analysis was carried out using a completely randomized design (CRD) with three replications. The results of this study compared with SNI 03-2105-2006. The density value of from 0.52 to 0.73 g / cm3, 1.67 to 4.32% moisture content, water absorption in immersion 2 hours from 1.88 to 11.41%, and a 24-hour immersion 5.38 to 28 , 48%, thickness swelling at 2 hours of immersion from 0.21 to 0.41%, and 24 hours from 0.43 to 0.69%, MOE 2710-6170 kg / cm2, MOR 50.72 to 128.49 kg / cm2 IB 1.11 to 2.94 kg / cm2. Variations in the composition of the plastic polypropylene (PP) and banana stem particles affect the physical and mechanical properties of plastic boards. Treatment on the composition of 70:30 is the best treatment for physical and mechanical properties of plastic boards.
