Abstract
Abstract.Bamboo waste processing can be an alternative raw material for products, reducing production costs and environmental impacts. Sayegan Hamlet, Sleman, Yogyakarta, is a center for the bamboo craft industry that produces large amounts of waste that is only thrown away. Therefore, research was conducted on processing bamboo waste into composites. The purpose of this study was to utilize petung bamboo waste as an alternative raw material in the form of composites for small industries. The research method was laboratory experiments and composite application trials to make furniture products. The composition of the bamboo waste composite (matrix) with weight fractions of 10g, 20g, 40g, 60g, 80g and corn husk waste (filler) with a composition of 90g, 80g, 60g, 40g, 20g. The material was mixed with bioindustrial glue with a composition of 30% of the composite mass fraction. Each composition was mixed until homogeneous, then poured into a mold with a diameter of 25 cm and a mold measuring 30 cm x 25 cm x 3 cm, then hydraulically pressed for 24 hours. After drying, the composite was tested for tensile strength, compressive strength, and hardness. Based on composite test results, the maximum tensile strength value is 38.9 MPa (40SB-SJ), compressive strength 86.3 MPa (60SB-SJ), and hardness value 46.1 MPa (80SB-SJ). For composite applications used to make furniture, produced in collaboration with craftsmen to ensure the product is in line with trends and marketable. Utilizing bamboo waste can provide benefits for industry and SMEs as an alternative raw material.
