Pemanfaatan Sampah Plastik dalam Pembuatan Paving Block sebagai Alternatif Pengurangan Volume Sampah di TPA Batuan

Abstract

Batuan landfill is the only landfill in Sumenep Regency that has experienced overload for 2 years. One solution that can be made to overcome this problem is to make paving block products from plastic waste. The aim of this research is to determine the ratio of the mixture of paving block material with plastic waste which produces the highest compressive strength value. This research uses laboratory-based experimental research methods at the Structure Laboratory of the Faculty of Engineering, Jember University. Paving blocks are made in blocks with a mixture ratio of PET plastic (as a cement substitute) and sand of 2:1 and the addition of a mixture of 1%, 2%, 3%, 4% and 5% rice husk ash from weight of sand. Three test objects were made from each variation of the mixture with paving block treatment for 28 days. The variables in this research are the dependent variable is compressive strength, the independent variable is the ratio of 2 PET plastics: 1 sand (addition of 1-5% rice husk ash from weight of sand), and the control variables are PET plastic, rice husks ash and sand as materials for making paving blocks. From the research results it can be concluded that the highest compressive strength lies in the M3 treatment with a mixed variation of 2 PET plastics: 1 Mayang sand : 3% addition of rice husk ash from weight of sand with a compressive strength value of 11,7 MPa. The highest compressive strength value in the M3 treatment includes D quality paving blocks which are used for non-structural parts such as city park floors, home yard floors, and in places that do not have to carry heavy loads.
