    Abstract

    Kajian ini dilaksanakan untuk mencirikan beberapa sifat bod partikel daripada batang kelapa sawit untuk menentukan parameter optimum dalam menghasilkan bod partikel, kesan penambahan asid polilaktik (PLA) dan penggunaannya sebagai bahan fantom. Sampel bod partikel dihasilkan pada lingkungan parameter penghasilan dengan suhu tekanan dari 160 ºC kepada 200 ºC dan tempoh penekanan dari 20 min hingga 30 min pada ketebalan sasaran 5 mm, 10 mm dan 15 mm untuk menentukan parameter optimum untuk menghasilkan bod partikel daripada batang kelapa sawit dengan ketumpatan 0.8 g/cm3. Reka bentuk komposit putaran berpusat (CCRD) daripada perisian Kaedah Permukaan Sambutan (RSM) digunakan untuk menilai sifat mekanikal dan fizikal bagi mengenalpasti korelasi antara setiap parameter. Dengan purata parameter optimum untuk menghasilkan bod partikel yang diperolehi daripada peringkat pertama, bod partikel tanpa perekat dan bod partikel dengan penambahan PLA daripada batang kelapa sawit pada ketumpatan sasaran 0.8 g/cm3 dihasilkan untuk menilai kesan penambahan PLA terhadap bod partikel daripada batang kelapa sawit. This study was designed to characterize some properties of oil palm trunk particleboard to determine optimum manufacturing conditions, effect of adding polylactic acid (PLA) and its application as phantom material. Particleboard samples were manufactured at a range of manufacturing parameters with pressing temperature of 160 ºC to 200 ºC and pressing time of 20 min to 30 min at target thickness levels of 5 mm, 10 mm and 15 mm to evaluate optimum manufacturing conditions to manufacture oil palm trunk particleboard with density of 0.8 g/cm3. A central composite rotatable design (CCRD) of Response Surface Methodology (RSM) software was used to evaluate mechanical and physical properties to identify the correlation between each parameter. With the average optimum manufacturing condition obtained from first stage, binderless particleboard and particleboard with addition of PLA at target density of 0.8 g/cm3 were manufactured to evaluate the effect of PLA on oil palm trunk particleboard.
