Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh komposisi serbuk kulit kakao dengan  lidah mertua terhadap sifat fisis dan mekanis. Variasi komposisi bahan yang digunakan partikel serbuk kulit kakao dan serat lidah mertua adalah 70:0%, 50:20%, 35:35%, 20:50%, 0:70%. Parameter yang diukur adalah densitas, kadar air dan daya serap air, Modulus of Elasticity (MOE), Modulus of Rupture (MOR) dan kuat tekan sejajar. Hasil uji sifat fisis diperoleh nilai densitas terendah Uji mekanis berupa kuat lentur dan  kuat patah serta kuat tekan sejajar. Hasil pengujian didapatkan nilai densitas terendah 0,71 g/cm3 pada komposisi 20:50. Nilai kadar air papan terendah 1,29% pada komposisi 20:50. Nilai daya serap air terendah 1,97% pada komposisi 35:35 sedangkan nilai daya serap air tertinggi 11,8% pada komposisi 0:70. Hasil uji sifat mekanis diperoleh nilai MOE terendah didapat sebesar 1115,56 kg/cm2 pada komposisi 0:70 dan nilai MOE tertinggi sebesar 1830,17 kg/cm2 pada komposisi 35:35, Nilai MOR terendah 30,303 kg/cm2 pada komposisi 70:0 sedangkan MOR tertinggi 49,342 kg/cm2 pada komposisi 20:50. Hasil penelitian menunjukkan bahwa sifat fisis dan mekanis papan partikel yang didapatkan pada pengujian telah memenuhi standar mutu SNI 03-2105-2006. Berdasarkan persentase densitas pada partikel maka papan partikel yang dihasilkan termasuk jenis papan partikel berkerapatan tinggi. 

 

The research on the effect of composition cocoa skin powder and  sansevieria to physical and mechanical properties of particle board has been conducted. The composition variation between cocoa skin powder and filler sansevieria that used were 70:0, 50:20, 35:35, 20:50, 0:70. Parameter that researcher measured were density, moisture content, water absorption, Modulus of Elasticity (MOE), Modulus of Rupture (MOR), parallel compressive strength. The physical characteristics experiment result has showed that the lowest density is 0.71 g/cm3 on ratio 20:50 and the highest density is 1.26 g/cm3 on ratio 70:0. The water content has showed that the lowest is 1.29% on ratio 20:50. The lowest water absorption is 1.97% on ratio 35:35. The result of mechanical characteristics that shown the lowest MOE value is 1115,56 kg/cm2 on raito 0:70 and the highest value is 1830.17 kg/cm2 on ratio 35:35. The lowest MOR value is 30.303 kg/cm2on ratio 70:0 while the highest MOR value is 49.342 kg/cm2 on ratio 20:50. The physical and mechanical characteristic of the particel board obtained in the test have qualified from the requirement of SNI 03-2105-2006 quality standar. Based on the percentage of particle board density, the result of particle board is including in to the type of high density particle board.
