Rohman, Abdul (2008) STUDI PARAMETER FISIS KUALITAS MUTIARA. Undergraduate thesis, Department of Physics, Diponegoro University.



Have been research for physical parameter of pearl quality in reflectance and density of pearl. This research have been done for learning connection between physical parameter with the purity of pearl variety. Reflectance intensity measurement of reflectance angle have been measured on the same position with incidence angle. Density measurement have been done by measuring mass density and relative density by using X-ray. The pearl that observed are purity and imitation pearl. From this research show that intensity reflectance of purity pearl is lower than imitation for same colour, using red and green laser show that the result pattern of intensity relectance is different and the density of purity pearl is higher then imitation pearl. The result show that physical parameter applicable to learn the quality of pearl variety.
