<![CDATA[They modified the blades and shaft of hammer mill for increase fish meal production capacity. The purpose is an effort to increase the moment of torque tools that can generate a more efficient time and amount of production of fish meal. Modifications performed by the addition of the flywheel on the shaft hammer mill, which includes several tests, namely (1) variations in engine speed, (2) the number of blades, (3) makes an angle of blade 1350.Base on three times repetition of the sample results, obtained by the capacity of fish meal as follows: (1) Increase by 78% at 1750 rpm rotation, the number of blades 27 pieces and shape of the blade angle 1350, (2) decreased by 68% at 1750 rpm rotation, the number of blades 18 pieces and form a straight blade, (3) decreased amounting to 56.6% at 1750 rpm rotation, the number of blades 18 pieces and form a straight blade. The results before and after the modified instrument obtained a difference 7.8 times the capacity (118 kg/15kg) or increase of 686% (118kg-15kg/15kgx100%). Techno economic analysis BEP values obtained for Rp. 326,403 kg per year, the percentage was 32.38% BEP, BEP capacity of 77,712 kg per year and the payback period is 2 years and 3 months.]]>
