One effort to improve the quality of oil palm trunk nutrients as beef cattle feed can be done with fermentation technology, this technology is quite cheap and applicable for farmers. The purpose of the research was to evaluate of technology bioproces in oil palm trunk on chemical composition and in vitro fermentation characteristics. This research used Randomized Block Design (RBD) with 3 treatments and 4 replications. The treatment consisted of A1: oil palm trunk without treated; A2: fermented oil palm trunk using Phanerochaete chrysosporium; A3: fermented oil palm trunk using starbio. The results obtained showed that the treatment effect was higly significant differents (P<0.01) on In vitro digestibility dry matter (IVDM), In vitro digestibility organic matter (IVOM), In vitro digestibility crude protein (IVCP) and fiber fraction digestibility (NDF, ADF, cellulose and hemicellulose), whereas VFA, NH3 and pH were not siqnificant different (P>0.05). This research we can conclude that the best treatment that produces the highest digestibility was treated A2 (fermented oil palm trunk using Phanerochaete chrysosporium) whereas IVDM : 61.56%, IVOM : 49.90%, IVCP :75.91%, and in vitro digestibility of ADF : 69.63%, NDF : 63.73%, Cellulose: 69.53%, Hemicellulose : 68.84% respectively, whereas rumen characteristic such as pH : 6.96, NH3: 9.20 mM and VFA: 144.61 mM, respectively.
