Abstract

Harvesting of cow's milk by SPR breeders is generally still done manually, which greatly affects the quality of the milk obtained. To test the quality of cow's milk, one method is to test for microbial contamination using the Total Plate Count (TPC) method. The problem that arises during testing is that calculations performed by analysts manually still require a lot of time. The focus of this study is to calculate bacterial colonies using digital image processing (PCD) techniques which can shorten the time for testing performed by analysts. The stages in implementing PCD are image acquisition, preprocessing (cropping process and conversion of YCbCr color space), Image Enchanchement (Combination of color space and addition of Brightness), Image Segmentation (Tresholding), Feature Extraction based on area (Channel Area Tresholding), and image classification process based on the TPC calculation method. The results of the research that has been carried out have an accuracy rate of detection of bacterial colonies which reaches 89% with an average detection error rate of 11.4%. Thus this system can assist analysts in performing TPC calculations automatically.
