Abstract
This research aims to determine the effect of adding filler material in the form of waste material on Nitrile Butadiene Rubber (NBR) in making roller rubber to improve quality in terms of hardness and tensile strength. Each rubber roller compound is made from a mixture of NBR with rice husk, waste rubber and wood charcoal. The test of hardness and tensile strength were done. The test results show that the addition of rice husk can increase hardness by 30% when compared to NBR without the addition of filler. While the value of tensile strength for NBR, and waste rubber alloys is much higher because this alloy is much more elastic.
