Abstrak
Telah dilakukan pembuatan dan karakterisasi mekanik papan partikel berbasis cangkang buah karet dengan perekat limbah plastik polipropilen. Papan partikel dibuat dengan variasi berat serbuk cangkang buah karet masing-masing 50 gram, 100 gram dan 150 gram, dicetak dengan ukuran 28 cm ´ 12 cm ´ 4 cm. Campuran serbuk cangkang dan perekat selanjutnya dikempa menggunakan alat press sederhana selama 1 jam dalam keadaan panas, kemudian didiamkan selama 7 hari pada suhu kamar. Karakterisasi papan partikel meliputi pengujian sifat fisika dan sifat mekanik. Papan partikel yang terbuat dari limbah plastik polipropilena dan cangkang buah karet memiliki kerapatan 0,81 – 0,88 g/cm3, kadar air 0,34 – 0,93%, daya serap air 5,67 – 10,69% dan tebal pengembangan 0,26 – 1,62%. Hasil uji sifat mekanik papan partikel dari serbuk cangkang buah karet dan plastik polipropilena menunjukkan nilai keteguhan patah 53 – 56,54 kgf/cm2, nilai keteguhan elastis 253,85 – 400,87 kgf/cm2 dan kuat cabut sekrup sebesar 1,96 kgf/cm2.

Abstract
Preparation and characterization mechanical properties of particles board based shells fruit rubber use plastic of polypropylene waste as adhesive has been done. Preparation of the Particle board based shells fruit rubber and plastic of polypropylene addition with variation of 50, 100 and 150 grams. The Particle board was printed on the same size 28 cm ´ 12 cm ´ 4 cm. Blending of the internal shell powder and adhesive of polypropylene used a hot press for 1 hour, then settled for 7 days at room temperature. Characterization the particles board includes of the physics and mechanical properties. It is the density 0.81 – 0.88 g/cm3, of the water content 0.34 – 0.93%, water absorption 5.67 – 10.69% and the thickness board expansion 0.26 – 1.62%. The values of MOR and MOE of particle board was 53.00 – 56.54 kgf/cm2, and 253.85 – 400.87 kgf/cm2. The values of strong pull secrew was 1.96 kgf/cm2.
