Abstract

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.

Abstract

Research analysis of the tensile strength of the weld on the battery to power an electric current battery has been done. The goal is to determine the tensile strength of welded joints using welding batteries with a variable flow battery, the thickness and diameter of the test material. Research methodology, including: (1) assemble welding battery (battery consists of 3 pieces) with the desired total current is 60 A, 80 A and 120 A, (2) arranging charging the battery  and welding handle  bar positive and negative, (3 ) welding on iron plate with thickness 4mm, 6mm and 8 mm with a current 60 A, 80 A and 120 A, (4) on an iron rod diameter 8mm, 10mm, and 12 mm with a current 60 A, 80 A and 120 A. The results showed the shape of specimens of iron, welding tools and strong currents thickness / diameter significantly influence the tensile specimens welded with welding tools batteries. The best treatment to iron rod the current round is 60 A at 8 mm diameter tensile yield amounted to 11.65 kg/mm2. The best treatment for the current iron plate is 80 A at 8 mm thick plate produce a tensile strength of 38.2 kg/mm2. From the calculation of economic, investment and operational costs-making tools, welding batteries cheaper than welding inventer and welding dynamo. However, welding batteries can not be regulated the size of the battery current.
