Abstract


The Badan Pusat Statistik (BPS) data for 2021 shows that the total rubber production
in Indonesia reached 2.877,90 tons. The high amount of rubber production will
accompany many by-products, such as rubber seed shells and fruit shells. These
materials have not been widely used for commercial purposes. This research will use
rubber seed shells and fruit shells as brake pad filler. These materials are expected to
replace brake pads that still contain asbestos, even though asbestos harms human
health. Brake pads are manufactured using the cold press method, which has a
composition is 60% epoxy resin, 35% filler, and 5% nylon fiber. The observed
characteristics of the organic brake pad are mechanical, tribological, and thermal
behavior using rubber seed shell and fruit shell fillers. This research conducted several
results. Both friction coefficient values have met the performance values of the
standard commercial brake pad material. The rubber seed shell has better wear
resistance as filler in brake pad material than fruit shells. The type of wear for rubber
seed shells is abrasive wear. The thermal analysis shows that the decomposition
temperature of the rubber fruit shell is higher than the rubber seed shell.
