      Abstract
      Tandan kosong kelapa sawit (TKKS) berpotensi dijadikan bahan baku produksi bioetanol. Produksi bioetanol terdiri atas beberapa tahap, salah satu tahap termahal adalah hidrolisis. Penggunaan enzim xilanase, feruloil esterase (FAE) dan enzim komersial Cellic® Ctec2 dapat digunakan untuk mengefisienkan proses hidrolisis. Penelitian ini bertujuan memanfaatkan TKKS sebagai bahan baku produksi bioetanol dan mengoptimasi konsentrasi enzim cocktail untuk sakarifikasi yang terdiri atas enzim xilanase, FAE, dan Cellic® CTec2, dan fermentasi bioetanol menggunakan Saccharomyces cerevisiae dengan metode sakarifikasi dan fermentasi simultan (SFS). Tahapan penelitian meliputi praperlakuan bagas tebu sebagai bahan baku produksi enzim, produksi enzim xilanase dan FAE, dan reaksi SFS. Hasil penelitian menunjukkan bahwa belum didapatkan konsentrasi optimum enzim cocktail karena konsentrasi etanol pada perlakuan penambahan enzim tidak berbeda nyata dengan kontrol.
       
      Palm oil empty fruit bunch (EFB) is potential as raw material for bioethanol production. Bioethanol production consists of several stages; the most expensive one is hydrolysis. The use of xylanase, feruloyl esterase (FAE) enzymes, and the commercial Cellic® Ctec2 can be used to streamline the hydrolysis. This study aims to utilize EFB as a raw material for bioethanol production and optimize the cocktail enzyme concentrations for saccharification consisting of a xylanase, FAE, and Cellic® CTec2 enzymes, and bioethanol fermentation using Saccharomyces cerevisiae through the saccharification and simultaneous fermentation (SSF) method. The research stages include the implementation of sugarcane bagasse as a raw material for enzyme production, the production of enzymes xylanase and FAE, and the SSF reaction. The results showed that the optimum concentration of cocktail enzymes had not been obtained because the ethanol concentration in the enzyme addition treatment was not significantly different from the control.
