Indonesia is one of the largest palm oil (CPO) producing countries in the world. With the increasing amount of CPO production and the increase in the area of oil palm plantations, the waste produced also increases. Among them are Empty Palm Oil Bunches or abbreviated (TKKS). The utilization of TKKS waste is currently still relatively not optimal, from these problems there is the potential to develop the potential utilization of oil palm empty bunch fiber (TKKS) as a composite filling material. This study was conducted to obtain the optimum parameters for the manufacture of composites using the vacuum infusion method. Comparison of the effect of levels on three different factors that have the most significant effect on the mechanical strength of composite materials. The factor used is the amount of vacuum pressure (0.2 bar, 0.5 bar, and 1 bar), then the factor of the length of the vacuum process (1 hour, 2 hours, and 3 hours) and the third factor is the fiber volume fraction (10%, 20%, 30%) which is then tested Tensile and impact. After being analyzed by the taguchi method and ANOVA, the results of the test showed that the most optimal parameters in the tensile testing of TKKS fiber composites with the vacuum infusion method were the combination of B2-L2-F3, namely a vacuum pressure of 0.5 bar, a vacuum process time of 2 hours, and a volume fraction of 30% fiber where the Ultimate tensile strength value was 25.48 (MPa) Similarly, in the impact test, the most optimal parameters were the combination of B2-L2-F3, namely a large tensile strength fiber. Similarly, in the impact test, the most optimal parameter is the combination of B2-L2-F3, namely a vacuum pressure of 0.5 bar, a vacuum process time of 2 hours, and a volume fraction of 30% fiber. which has an HI value of 0.186 (J/mm2).
