Conversion of agro‑industrial wastes of sorghum bagasse and molasses into lightweight roof tile composite
Penulis: AlifahSyahfitri, S.Hut ; Dr. Ir. Dede Hermawan, M.Sc., jajang sutiawanParticle of sorghum bagasse (SB) and molasses are by-products of sugar factories which potential as resources to manufacture renewable composite. The aims of this study are to manufacture composite roof tile from particleboard using biomass of sorghum and molasses, in addition, analyze the efect of molasses content and particle size’s sorghum on the properties of composite roof tile. The roof tile composites were produced at a target density of 0.8 g/cm3 and 300×300×60 mm in size using a hot-pressing machine at a temperature of 200 °C for 20 min with a pressure of 5 MPa. The characterization and testing methods were carried out based on the Japanese Industrial Standard (JIS) A 5908:2003. The composite roof tile has been successfully made by combination sorghum biomass and molasses. Lightweight roof tiles can be used as an earthquakeresistant roof component. The density, moisture content, and internal bonding of roof tile lightweight composite fulflled the JIS A 5908:2003. Statistical analysis suggested that a combination of 20% of molasses-based adhesive content and a 4–20 mesh size of SB’s particle could be used to manufacture roof tile lightweight composite with proper physical and mechanical properties according to the JIS A 5908:2003 standard. The result of FTIR and PY-GCMS confrmed that molasses was composed of 5-hydroxymethylfurfural (5-HMF) from the sucrose compound.
