Preliminary studies of testing samples using optical fiber sensors were carried out to obtain the appropriate data results and compared with UV-Vis spectrometers as well as to obtain optical characteristics of lard compared with other fat samples. The test method used instruments such as ocean optics HR4000CG-UV-NIR and DH-2000-BAL UV-Vis light source (halogen) NIR with wavelength range (200-1200) nm. The results of testing pure pork samples (chicken and beef mixture) with optical fiber sensors obtained peaks at λ = 715 nm and λ = 937 nm. The characteristics possessed by pure pork samples are high intensity (reflecting) values and low absorbance (absorption). Tests carried out with optical fiber indicate the detection of pure lard content or with a mixture of other ingredients. The graph of absorbance relation to concentration shows an upward linear trend with a value of R 2 0.092193, 0.9474 and 0.95901.
