%X This research was motivated by the discovery of white tofu preserved using formalin. This  study aimed to analyze formalin contaminants in tofu and determine the precision and  detection limits of a fluorescence spectroscopy system based on high power UV-LED.  This research was conducted in three stages, namely making samples, collecting data,  and processing data. The sample was made directly in the tofu factory with the owner and  the object used in this study is white tofu which was given a variation of formalin  contaminants 0%-50%. Data were collected using a set of fluorescence spectroscopy  system based on high power UV-LED that is connected to software LabVIEW and each  foreign formalin contaminant test in tofu used five samples with three repetitions for each  sample. Data processing to obtain bin values ​ ​ for each a variation of formalin  contaminant was carried out using Microsoft Excel, moreover to find a value of precision  and a detection limit . This research has successfully analyzed formalin contaminants in  tofu using a fluorescence spectroscopy system based on high power UV-LED with a  precision test result of 100% and a detection limit of 12.05%.
