Abstract

The high demand on renewable energy nowadays is due to the fossil fuel depletion. Biomass is one of the renewable energy sources and coconut can be constituted by converting it into biomass pellets. However, the coconut that been used is only from old type because the moisture content that contains in virgin coconut type is too high and not suitable for biomass pellet production which need low moisture content. This paper reports the optimum moisture level of young coconut waste and hot flue air speed in drying that waste based on retention time and moisture level consistency with the constant temperature hot flue air of 53.3o C. The materials were crushed and sieved to get grain form with size below 0.08 mm before be dried with speed 7.40 m/s, 10.45 m/s and 12.54 m/s to obtain optimum moisture level that stipulated between 8% to 20% with a high moisture level consistency and low retention time. The samples of grain then were characterized by produce a pellet with compression method by hot press machine with temperature 120o C, 130o C and 140o C while pressure of 5 MPa, 7.5 MPa 10 Mpa and 12.5 MPa besides retention time of 3, 4 and 5 minutes. The 8 % is the optimum moisture level and the speed of 7.40 m/s is the optimum hot flue air speed that give low retention time and consistency moisture level besides low cost on electric energy consumption.With optimum value of hot flue air speed in drying process, the optimal and consistency of moisture level and retention time for new biomass pellet production that functions as a green fuel and burner has been achieved and indirectly overcome the issue of land side fulfilment and environment pollution besides accommodating the fossil fuel depletion and gain income from waste sources.
