    Porous carbon material was synthesized from sugarcane bagasse by 2 steps. Firstly, increase the surface area by treatment bagasse via using hot-compressed with mixture of ethanol/water in various concentrations (0-100%v). Secondly, transform the pretreated bagasse to porous carbon by carbonization under nitrogen at 900°C for 2 hours. The highest surface area was found at a pretreatment temperature 180°C with mixture of ethanol-water 25%v and specific surface area was 382 m<sup>2</sup>/g while raw bagasse without pretreated was 189 m<sup>2</sup>/g. Pretreated bagasse and porous carbon were analyzed by Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FT-IR) analysis and surface area measurement by N<inf>2</inf> adsorption (BET). The result was showed that organosolv pretreatment using ethanol mixed water can increase the surface area and porosity of bagasse.

    Bio-oil or pyrolysis oil can be obtained from fast pyrolysis biomass has several unusual characteristic such as high acid and high oxygen content which cause bio oil not proper to use as a fuel. In this research MoS<inf>2</inf> support on carbon material was prepared for the upgrading bio oil via impregnation method on carbon support from biomass. Hydrothermal process which aims to convert biomass into value products. This process usually performed in water and produces the product, namely hydrochar. In this research, bagasse were executed by hydrothermal at 160 °C, 180 °C and 200 °C for 2, 4, 8 and 24 hours each to enhance the porosity of their products. High porosity is well-known desirably for enhancing efficiency of supporting agents since it can load more catalyst quantity. After finishing hydrothermal process, the reactor which carried bagasse was quenching in order to inhibit the reaction inside. Then, the hydrochar was impregnated by MoS<inf>2</inf> precursor and carbonized at 450 °C for 2 hours under nitrogen atmosphere to stabilize the metal phase and turned hydrochar into carbon support. MoS<inf>2</inf>/carbon was characterized by scanning electron microscopy, EDX, FTIR and pyrolyzer gas chromatography/mass spectroscopy.
