PENGOLAHAN LIMBAH PLASTIK DI WILAYAH KEL. CEMPAKA MENGGUNAKAN MESIN PELUMER PLASTIK

Abstract

Plastic waste is still a big problem in Cempaka Village, Banjarbaru City. It is estimated that every day there are 2-3 sacks of plastic garbage that accumulate from residents' waste. Mostly in the form of plastic packaging bags, cups, and bottles of drink. One of the efforts in realizing the concept of zero waste is to recycle plastic waste, which is plastic waste processed into paving block products. Therefore, we need a tool to melt the plastic. The method used is to conduct a field study and make a garbage bucket machine with dimensions of length 60.3 cm diameter 60 cm, liquid plastic flow capacity is 1.25 kg/minute and the stirrer round is 40 Rpm, with a production capacity of 20 pieces of paving blocks/hour, the temperature to melt plastic is 250oC260oC. The time needed to melt HDPE plastic is 60 minutes and PET plastic

is 30-40 minutes. The results of the paving block bending test averaged 11.58

MPa.
