The design of this test equipment is an extension of the ASTM D5470-06 standard, where the same is used to calculate the surface temperature and heat transfer through the sample during the test, where at each reference rod point, 10 K-type thermocouples are embedded. The maximum heater power required by the reference rod with a heating time of 1 hour is 30.4 KW. This test tool uses 3 pieces of 500-Watt power, and Thermoelectric TEC1-12706 12 Volt 6 Ampere 40x40 mm, Heatsink, 12 Volt DC Fan 0.15Ampere 38x38 mm, to keep the test at a steady state. And the use of Thermal Paste to minimize thermal contact resistance. From the calculations, it can be seen that the faster the time needed to heat the reference rod will require greater heater power, and vice versa. For high temperatures, this tool can reach a test temperature of 100 ℃. This research was conducted to measure the thermal conductivity of stainless steel, iron, wood, rubber, and Styrofoam. After the measurement, the thermal conductivity of stainless steel was 15.14037 W / mK Reference 14.00 W / mK, iron 41.07 W / mK Reference 79.5 W / mK, wood 1.54 W / mK Reference 0.21 W / mK, rubber 0.6 Reference 0.2 W / mK, Styrofoam 0.062 W / mK Reference 0.095 W / mK.

Using foamed polymer composites reinforced with natural fibers continues to be researched and developed to obtain alternative materials to replace metals. Composite materials have unique characteristics and are lighter in weight. Natural fibers from bagasse fiber can function as reinforcement in polymer composites. This study aimed to obtain the effect of variations in bagasse fiber on composite polymer foam materials due to compressive strength loads. This polymer composite material was made by varying bagasse fiber with a mesh fiber size of 300, 400, and 500. Three variations of the constituent materials were measured based on the density ratio of the materials. The constituent materials consist of resin, polyurethane, and fiber, respectively are: label A = (85%, 15%, 0%); label B = (84%, 15%, 1%); Label C = (83%,15%, 2%); and label D = (82%, 15%, 3%). Specimens, for each composition, are three specimens. The technique for making specimens uses the method of pouring into molds concerning ASTM D-638.
