Observations of graph 4.1.1 show the maximum stress that occurs on specimen 1 with higher percentage of epoxy resin. The tensile
strength of each specimen varies depend on percentage of epoxy resin. The test results show that the tensile strength of the
composite material affects the straw fiber.

Table 4.2.1 Flexural Test Data Results

Based on the above information data, the table describe the maximum amount of composite material pressure from each
specimen. The maximum pressure received through rice straw fiber composite material with epoxy resin is 0.338 kN / ². The
lowest compressive stress on the flexural test specimen is 0.145 kN / 2 which is 60% of the epoxy resin used. All specimens
were categorized according to a predetermined percentage of epoxy resins.
