Analisa Hubungan Kontras Spekel Terhadap Indeks Bias Madu Menggunakan Metode Laser Speckle Imaging

---

Laser speckle imaging (LSI) method is a non-destructive imaging technique that can be used to detect optical signals from biological tissues in the form of dark and bright grains called speckle patterns. This study used the LSI system to determine the speckle contrast and refractive index of honey using laser diodes with a wavelength of 650 nm, Riau native forest honey and branded honey as samples, and a monochrome CMOS camera as a detector. Honey is varied in water content by adding aquades by 0%, 5%, 10%, and 15%. Each sample varied by the water content was divided into three cuvettes and then the images of the honey specimen was recorded. Recording of honey images was carried out to determine the speckle contrast value of honey using ImageJ software based on the value of the intensity and standard deviation of the specimen. The measurement of water content and sugar content contained in honey was done using a Brix refractometer, then the refractive index can be determined using a conversion table of sugar levels to the refractive index. The results showed that the addition of water content to honey affected the value of speckle contrast and refractive index of honey. High water content produced a low speckle contrast value and a low refractive index. The contrast value and the refractive index had a linear relationship. The greater the contrast value of the speckle, the greater the refractive index of honey depens on each type of honey.
