Abstract

This study aims to determine the effect of using PCM in reducing the temperature of the water entering the radiator from the engine. Two types of PCM used are made of aluminum and ST 37 steel. They are made like a box measuring 8 cm x 8 cm with a thickness of 2 mm, the center hole is 3.5 cm in diameter, totaling eight pieces. The Machine used is L 300 Colt engine. The results of the study explained that the decrease in engine temperature after using PCM reached 17.50C. While the use of PCM is very effective where the water coming out of the machine can be reduced by 17,830C. Engine speed at stationary conditions (800 rpm – 1100 rpm) aluminum PCM is more effective, but at engine speed starting (1250 rpm – 2000 rpm), the effective PCM is ST 37 steel.

Abstract

This study aims to determine the separation of kerosene and water in a piping installation. It is very important to do research because it can reduce problems that arise in the distribution of drilling oil to further processing and distribution. T-Junction is a method used in this study, because the separator method is rarely used. The separation of kerosene and water types in the test using the T-Junction method, variations in downstream flow resistance of 42%, 57% and 72% resulted in a large kerosene separation efficiency of 100% at a mixed superficial velocity of 0.35 m/s, Jw= 0.25 m/s Jk = 0.10 m/s and at mixed superficial velocity 0.47 m/s, Jw = 0.22 m/s Jk=0.25 m/s, while 99% efficiency occurs at mixed superficial velocity 0 ,20 m/s , Jw= 0.10 m/s and Jk = 0.10 m/s. Water cut also greatly influences the phase separation. The lower the water cut, the higher the peak separation efficiency achieved
