LEGOBLAS (Lego Bata Plastik) Eco-friendly Solution for Plastic Waste Accumulation

Abstract

The problem of waste generated by activities at UNESA can threaten the health of the environment and the welfare of the surrounding community. A solution is needed to overcome the waste problem in the UNESA environment. One solution that can be taken is to make paving blocks from plastic waste, or it can be called LEGOBLAS. This research aims to improve previous research and utilize plastic waste to be used more beneficially. In this study, data was collected through LEGOBLAS testing, which included testing for compressive strength, absorption, slipperiness, and heat strength. In addition, supporting data is also collected through external observation and LEGOBLAS measurements, including the length, width, height, and mass of LEGOBLAS. The method applied in this study is descriptive quantitative; the form of data presentation is in the form of numbers, which are then analyzed using the LEGOBLAS test. Making eco-friendly LEGOBLAS goes through several stages, including sorting plastic waste, melting plastic waste, and printing LEGOBLAS. Melting plastic using used cooking oil aims to prevent the chlorine content from being released into the air so that it is environmentally friendly. Compressive strength testing using a Compression Testing Machine, Slippage test using a Surface Roughness Tester, Absorbency Test by immersing LEGOBLAS in water for 10 minutes, and Heat Resistance Test by baking for 12 hours at 38°C. Action is needed to reduce this plastic waste; one way to reduce this plastic waste is by making LEGOBLAS a utilization of plastic waste.
