Abstract

This research aims to analyze the performance of oil-water separation using a hydrocyclone-bubble generator. The bubble generator used was an ejector type to make it easier to suck in atmospheric air. The research was carried out by injecting an oil-water mixture through a bubble generator before entering the hydrocyclone system. The air flow injected into the bubble generator was varied from 0.1-1.5 lpm. From experimental studies, it was found that as the air flow increased, the split ratio also increased. The pressure drop at the overflow increases gently while the underflow pressure drop increases significantly along with increasing input air flow. The greater the input air flow, the more significant the difference in underflow and overflow pressure drop. It has implications for a larger pressure drop ratio. The greater the air flow, the greater the overflow efficiency decreases, and the underflow efficiency increases. The highest efficiency in overflow is 87.77%.

Abstract

Casting is the process of manufacturing molten metal with a mold to produce a shape close to the original shape. The commonly used molding sand is mountain sand, river sand and silica sand. This research aims to analyze defects and tensile test results of castings with various types of sand (beach sand and silica sand) and types of aluminum (ADC 12 aluminum and aluminum from waste cans). The casting method used is traditional sand blasting. The results show defects in the form of surface hardness, rat tails, shrinkage cavities, and pinholes. The tensile test showed that the highest Ultimate Tensile Strength (UTS) value was obtained from a mixture of Al ADC 12 with beach sand with an average UTS value of 172.44 MPa.
