Abstract


ABSTRACT
The aim of this research was to study the effect of solid waste of leather tanning industry
(shaving) to physical properties of PVC particle board. Particle board was produced from PVC,
additives material and solid waste of leather tanning industry (shaving). The variation of solid
waste (shaving) content are 0; 10; 20; 30; 40; 50; 60; and 70 phr respectively. The compound was
made by mixer and two roll mill unheated, mixing by torque speed 30 rpm. Press condition are
165oC, 150 kg/cm2, and it needs 6 minutes for 2 mm thickness and 30 minutes for 10 mm
thickness (depend on kinds of test). The particle board was tested physical properties by methods
of SNI 03-2105-2006 Mutu Papan Partikel. The test result of physical properties showed that
solid waste of leather tanning industry for particle board was significant enfluence to increased
tensile strength, water contains, thickness swelling, but decreased screw withdrawl and
flexibility. Solid waste of leather tanning industry (shaving) added was not significant influence
to density.


Keywords: particle boards, polyvinyl chloride, shaving learther, physical properties


ABSTRAK
Tujuan penelitian ini adalah mempelajari pengaruh penambahan limbah padat IPK
(shaving) terhadap sifat fisis papan partikel dari PVC. Papan partikel dibuat dari bahan plastik
polivinil chlorida dan bahan pembantu serta limbah padat IPK (shaving). Penelitian dilakukan
dengan memvariasikan jumlah limbah padat IPK (shaving) yaitu 0; 10; 20; 30; 40; 50; 60; dan 70
phr. Pencampuran dilakukan dalam mixer, dan alat two roll mill tanpa panas, diputar dengan
kecepatan putar torsi 30 rpm. Kondisi pengepresan adalah: suhu 165oC, tekanan 150 kg/cm2,
waktu 6 menit untuk tebal 2 mm dan 30 menit untuk tebal 10 mm (tergantung jenis uji). Papan
partikel yang diperoleh diuji sesuai SNI 03-2105-2006 Mutu Papan Partikel. Hasil pengujian
sifat fisis menunjukkan bahwa limbah padat IPK (shaving) pada kompon polyvinyl chloride
untuk papan partikel, berpengaruh nyata menaikkan sifat kuat tarik, kadar air, pengembangan
tebal, tapi menurunkan sifat kuat pegang sekrup, dan kuat lentur. Penambahan limbah padat IPK
(shaving) tidak berpengaruh nyata pada sifat kerapatan massa.


Kata Kunci: papan partikel, polyvinyl chloride, limbah padat IPK (shaving), sifat fisis
