The purpose of this study is to determine the effect of natural ingredients treatment such as turmeric (Curcuma) on a fiber sheath Akaa (corypha) toward the fiber tensile strength. The first step is soaking the Akaa fiber sheath in a distill water and then dried it up at a room temperature for about 48 hours. The second step is boiled the fiber in a turmeric solution for about 1 hour and then dried it up at a room temperature for 48 hours. The third step is boiled again in the turmeric solution for about two hours and again dried it up in the room temperature and finally boiled it in the turmeric solution again for three hours and then dried it up again about 48 hours in a room temperature. The fiber boiling process in the turmeric solution temperature is about 100C and under a pressure of 1 atmosphere. The turmeric solution used has a concentration of 20% turmeric and 80% volume unit distilled water. The fiber was then observed for the fiber tensile strength with a specimen shape standardunder the ASTM 3309-02 regulation. The other observation was the SEM testing with the X-Ray Energy Dispersive Spectroscope (EDS) and lastly the FTIR testing. From the research result it isknown that the highest single fiber tensile strength was found on the fiber which was treated about one hour boiled in the curcuma solution. © Research India Publications.
