Analisa Hubungan Antara Nilai Rgb Dengan Sifat Fisika Dan Kimia Madu Menggunakan Metode Pencitraan Fluoresensi Berbasis Laser
The physical and chemical properties of honey are parameters that can be used to determine the quality of honey. One of the physical and chemical parameters of honey are sugar content and viscosity. The fluorescence imaging method was used to analyze the relationship between RGB values and the physical and chemical properties of honey. This method is used because of its simplicityand non-destructive nature. The fluorescence imaging system consisted of a 405 nm purple laser, mirror, ND filter and RGB CMOS camera. The sampleswere ten types of honeynamely Riau forest honey and branded honey. The samples were given 0% (original honey), 10%, 20% and 30% corn syrup. Sugar and viscosity levels were measured manually using a brix refractometer and Ostwald viscometer. The honey images were recorded and processed with ImageJ software to obtain the RGB value. The results showed that the lower the RGB honey value, the lower the honey viscosity value with an incrrease of corn syrup variation. Correlation of RGB values with viscosity was 0.923, 0.985; 0.882; 0,865, 0,845; 0.911; 0,840; 0.968; 0.740 and 0.962 respectively. The lower the RGB honey value, the lower the honey sugar content with an incrrease of corn syrup variation. Correlation of RGB values with sugar content was 0,794; 0,975; 0,936; 0,838; 0,902; 0,981; 0,908; 0,860; 0,902 dan 0.958 respectively.
