This study aims to analyze and show how calculate EOQ prove that the use of method can make inventory costs efficient because number purchases is not excessive lacking, frequency exact time reordering. The theory underlying this research management, especially Single Item Method. analysis technique used descriptive using Optimalization , purchase (N), Reorder Point (ROP) results showed cost eff...

The power factor (PF) is an important measurement in AC electrical system that indicates how much ‎is utilized to accomplish productive work by a load and consumed. As result, it's one of ‎the primary causes excessive energy costs outages. This paper aims present simple, cost-‎effective, accurate PF metering monitoring implemented using Arduino microcontroller with ‎a novel methodology differen...
