ABSTRAK Perkembangan teknologi komposit tidak hanya pada komposit sintetis, akan tetapi juga mengarah pada komposit alam (Natural Composite) dikarenakan keistimewaan sifatnya yang dapat di daur ulang atau istilah lain terbarukan. Penelitian ini bertujuan membuat bahan komposit serat alam dan resin epoxy terhadap sifat mekanis. Pada penelitian ini, komposisi tandan kosong kelapa sawit dan serat kulit akasia dengan nilai 15%+5%, 10%+10% dan 5%+15% dengan bahan perekat resin epoxy 80%. Hasil uji bending menunjukkan bahwa campuran komposit 80% resin epoxy, 15 % serat tandan kosong kelapa sawit dan 5 % serbuk kayu akasia mempunyai nilai kekuatan bending yang terendah yaitu 9,95N/mm2, sedangkan campuran komposit 80% resin epoxy, 5% serat tandan kosong kelapa sawit dan 15 % serbuk kayu akasia mempunyai nilai kekuatan bending tertinggi yaitu 20,84 N/mm2. Hal ini disebabkan karena campuran serbuk kayu akasia memiliki struktur dari serat akasa lebih kasar, kuat, padat dan lebih berat dari pada tandan kosong kelapa sawit yang memiliki stuktur serat yang lebih ringan, rapuh dan berongga (tidak padat). Hasil kekuatan impact yang paling tinggi dari campuran serat alam 80% resin epoxy, 15% serbuk kayu akasia dan 5% TKKS dengan nilai 134 J/mm2. Hal ini disebabkan dari jumlah campuran dari akasia lebih besar maka kekuatan spesimen lebih tinggi kekuatannya karena semakin banyak serat akasia maka semakin terus meningkat kekuatan spesimen tersebut.

This study simulated the characteristics of the fluid flow that passes through the Darrieus turbine before installation and testing were carried out. The purpose of knowing the flow characteristics can determine the profile and position of the maximum speed so that the design and placement of the turbine can be improved. The research method was carried out using dynamic fluid computational simulations in three-dimensional form with steady state conditions, discretization using second-order, with convergent conditions when it reached 10-6. The simulation results show that the position of the flow above the turbine had the lowest value because the fluid flowed relatively without disturbance which caused the velocity to had a value almost the same as the incoming fluid velocity. The fluid velocity increased when it was in line 2 and line 3 or across the turbine. This was due to the turbulence generated by the rotation of the turbine. While the speed on line 4 or below the turbine had a lower value than line 2 and line 3. This was due to the position below the turbine so that the turbine rotation did not have an impact on speed. At the four line positions the velocity increased at Y=0.7 m or when the fluid hits the turbine. This increase in fluid velocity was expected to turn the turbine. The results also included the flow distribution in the form of a streamline in several positions where the flow that was in contact with the channel wall had a low velocity value due to friction with the wall.
