      Abstract
      Indonesia merupakan Negara dengan areal perkebunan yang luas. Salah satu komoditas perkebunan yang melimpah di Indonesia adalah karet dan kelapa sawit. Karet terbagi menjadi 2 jenis yakni karet alam dan karet sintetik. Keduanya memiliki sifat kepegasan pantul yang baik. Namun, dalam pemenuhan sifat mekanik baik karet alam maupun sintetik diperlukan adanya bahan pengisi (filler), salah satunya adalah serat Tandan Kosong Kelapa Sawit (TKKS). Penelitian ini bertujuan untuk menganalisa pengaruh konsentrasi filler serat woven TKKS dalam bentuk biokomposit tersusun laminar terhadap kekuatan mekanik karet (alam dan sintetis). Pembuatan biokomposit dilakukan dengan metode hot press. Uji mekanik matrik karet yakni tensile strength, elongation at break, dan rebound resilience menjukan sifat mekanik matrik terbaik adalah karet butyl. Uji impak biokomposit menunjukan sampel terbaik adalah sampel CNR-70, yakni biokomposit bermatriks karet alam dengan hardness 70 dan konsentrasi filler serat TKKS sebanyak 28 lembar.
       
      Indonesia is a country with a large plantation area. One of the abundant plantation commodities in Indonesia is rubber and oil palm. Rubber is divided into 2 types, namely natural rubber and synthetic rubber. Both of them have good reflective properties. However, in fulfilling the mechanical properties of both natural and synthetic rubber, a filler is needed, one of which is the fiber of the Empty Oil Bunches (EFB). This study aims to analyze the effect of the concentration of the OPEFB woven fiber filler in the form of a laminar composed biocomposite on the mechanical strength of rubber (natural and synthetic). The biocomposite was made by hot press method. Rubber matrix mechanical tests, namely tensile strength, elongation at break, and rebound resilience showed that the best matrix mechanical properties were butyl rubber. The biocomposite impact test showed that the best sample was the CNR-70 sample, namely the biocomposite with a natural rubber matrix with a hardness of 70 and a concentration of OPEFB fiber filler as much as 28 sheets.
