The determination of residual pesticides beta siflutrin in potato (Solanum tuberosum L) was conducted by Gas Chromatography (GC). The separation was conducted on a DB-1 (30m×0.25mm×0.25µm) coloum, using a nitrogen gas as mobile phase at flow rate of 25 mL/min. The determination of beta siflutrin in potato with GC was based on the verification method. The detection was ECD detector. Verification parameters tested were linearity, accuracy, precision, limit of detection (LOD), and limit of quantitation (LOQ). Linearity had a correlation coefficient (r) of 0.9992. Accuracy had a recovery value of 99.49%. Precision had a value of relative standard deviation (% RSD) of 2.48%. The limit of detection (LOD) and limit of quantitation (LOQ) obtained was 0.001305 and 0.00435 mg/kg. The result of this research showed that the method of determination of residual pesticides beta siflutrin in potato with GC can be used as a routine analysis.Key words: verification, beta siflutrin, GC, potato
