MetadataShow full item record
The research has been made biocomposites cornhusk and Linear Low Density Polyethylene (LLDPE) with hot press method. Biocomposites made with the variation of cornhusk:LLDPE are 30:70, 40:60, 50:50, 60:40, 70:30, and it is characterized of the mechanical characteristics (tensile and tear) with Universal Testing Machine (UTM), biodegradation in a qualitative manner and morphology by Scanning Electron Microscopy (SEM). Cornhusk are also analyzed the thermal characteristics with Differential Scanning Calorimetry (DSC), a functional groups by Fourier Transform Infrared (FTIR) and morphological analyzed by SEM. Mechanical analysis showed the mechanical characteristics decrease with the addition of cornhusk concentration on biocomposites, and concentration 30:70 has the highest mechanical characteristics with tensile strength 24.77 MPa, elongation 19.10% and tear strength 53.94 N/mm. The result is contrast with the biodegradable analysis in which the bigger concentration cornhusk then the level of biodegradability is higher. The result of mechanical analysis also supported by the analysis of morphology biocomposites and LLDPE. Analysis of a functional groups and morphology cornhusk showed that cornhusk had the high fibers with transition glass cornhusk at 196.21 oC.
