Abstract

The yield of oil palm fronds is 8.4 tons/ha/year [1], a huge potential that has not been used optimally. Particle Cement Board (PCB) is a biocomposite that uses inorganic adhesive, namely cement, to bind biomass particles into a board. Wood Plastic Composite (WPC) is a biocomposite that combines plastic and biomass particles molded into boards. This study used the same biomass particles—oil palm fronds—to analyze the properties of PCBs and WPCs. Characteristics assessment by measuring and testing physical and mechanical properties were density, moisture content, water absorption, thickness swelling, elasticity (MOE and MOR), and internal bond strength (IBS) of oil palm fronds PCB (refers and compared to JIS A 5417-1992 and SNI 8299-2017 standards) and WPC (refers and compared to JIS A 5908-2003 and SNI 03-2105-2006 standards). The test results on the PCB are density 1.143 g/cm3, moisture content 8.429%, water absorption 26.414%, thickness swelling 1.368%, MoE 188.899 N/mm2, MoR 5.765 N/mm2, and IBS 0.054 N/mm2. The test results on the WPC are density 0.84 g/cm3, moisture content 2.36%, water absorption 16.21%, thickness swelling 7.11%, MoE 590.87 N/mm2, MoR 13.40 N/mm2, and IBS 0.31 N/mm2. Oil palm fronds is quite well used as a raw material for making particle cement board (PCB) and Wood Plastic Composite (WPC)

Abstract

 Pengamatan dilakukan terhadap tujuh log sejak tahap pemotongan log, pembuatan dolok, pengulitan, hingga pengupasan dengan mesin rotary lathe konvensional bercakram. Volume log, dolok, finir kontinu, finir potong, dan poli-poli diukur menggunakan pendekatan input-output. Data rendemen dianalisis secara deskriptif dan dibandingkan antarjenis kayu menggunakan ANOVA satu arah. Rendemen total rata-rata masing-masing sebesar 64,08% untuk meranti merah, 77,21% untuk keruing, dan 62,85% untuk tengkawang. Meskipun keruing menunjukkan rendemen tertinggi, perbedaan antarjenis tidak nyata secara statistik (F = 0,447; p = 0,668), terutama karena jumlah sampel terbatas dan variasi antarlog yang tinggi. Limbah yang teridentifikasi meliputi lempengan log, kulit kayu, serbuk gergaji, poli-poli, finir sobek, dan empulur. Berdasarkan bentuk dan mutunya, limbah tersebut berpeluang dimanfaatkan secara bertingkat sebagai finir inti, komponen papan blok atau kemasan, bahan baku panel partikel dan serat, pelet, biochar, karbon aktif, produk berbasis tanin, serta bahan bakar boiler. Sortasi log, ketepatan penentuan titik pusat kupasan, pengendalian pisau dan nose bar, serta pemilahan limbah secara sistematis direkomendasikan untuk meningkatkan rendemen dan mendukung bioekonomi sirkular berbasis kayu.
