Abstract

Inductor with a metal core is a component which  is almost always present in the daily  electronic device known to us . To further prove the potential  of the proposed new metalcore material, it is necessary to test the voltage variation, winding, and frequency in the inductor with the newly proposed metallic core material. The research method uses experimental methods. Three basic metal materials were used in the experiment, those are Cast Iron ASTM A48 (C 3.4%, Mn 0.5%, Si 1.8%,), Nicromine (Ni 80%, Cr 20%), Monel Alloy 400 (Ni 63%, Cu 31.7%, C 0.3%, Fe 2.5%, Si 0.5%, Mn 2%, S 0.024%). Experimental tests on these new types of metal were also carried out under various stress, winding, and working frequency conditions. The voltage variation selected is 4.5 V - 24 V,  the winding variations and frequencies selected are 150 to  1000 turns and 50 Hz. The  greatest inductance was obtained from ASTM A48, Fe, Monel Alloy 400, Nikromic, and without metallic core on the specified indicator variables. As the voltage increases and the number of turns increases,  the inductance value increases.

Abstract

One of the causes of boiler pipe breakage is corrosion. The prediction of the lifetime of the tube and superheater effectiveness on the boiler shall be calculated to determine and predict the failure time. The prediction of the lifetime of the tube is a prediction of the time of the failure of the superheater tube in the boiler so that the return can be performed.  The effectiveness of the superheater in the boiler is a comparison of the heat transfer rate of the overheated tubes  inside the boiler. The research method was research and development, a computational program using an optimization process.  The variables used in the study were steam input temperature, metal tube temperature, steam outlet temperature, natural gas input temperature, natural gas mass flow rate,  vapour mass flow rate, and natural gas outlet temperature. This study takes a case study of the superheater boiler from the company. The results of calculation of the life expectancy of the operating conditions  shall be 11 years when the boiler data sheet is used and 14 years  for using the actual boiler data. Superheater effectiveness in boilers with 56% is a data sheet on boilers and 56% of the actual data. Optimization of the particle swarm algorithm predicted a  29 year  lifespan. The effectiveness of the superheater in the boiler is 86%.

Abstract

The ability of an industrial company to produce a product will certainly depend on the ability of the machine used as a tool to produce every part of the product. Over time, increased market demand must be accompanied by an increase in production rates. Where this requires industrial companies to have high productivity, especially in the machining parts used in the production process. We can measure this effectiveness using the Overall Equipment Effectiveness (OEE) method, which is often used to measure the productivity of the machine or equipment used. Based on the research results, it can be seen that the average value of Overall Equipment Effectivities (OEE) on a stamping machine is 39.9%.
