Abstract:
Oil palm trunk one of waste from plantation with huge population in Indonesia. Oil palm
trunk used to made variety product, for example as filler for wood plastic composite (WPC).
Objective of this study to determine process condition (temperature, rotor speed, and
blending time) to increase quality of WPC. Internal mixer type Labo Plastomill used to blend
oil palm stalk powder (OPSP) and polypropylene (PP) 50/50 by ratio while 2% plasticizer
paraffin and 5% compatibilizer maleic anhydride polypropylene (MAPP) as additives.
Blending process varied temperature 170ºC, 175°C, and 180ºC with rotor speed 60 rpm and
80 rpm for 10 minute and 15 minute. Mechanical properties for tensile strength used JIS K
6781 standard. This study show optimal mixing condition in temperature 170°C, rotor speed
80 rpm and mixing time 15 minute. Tensile strength obtain to 24,81 MPa.
