The FeSeTe superconductor is a newly discovered superconductor in 2008. However, there are several problems in the synthesis process, so there is a lot of research on the synthesis of FeSe superconductors. The purpose of this study was to determine the effect of diameter variations and variations in the composition of FeseTe stoichiometry, so that they could be used as one of the iron-based superconductor candidates. Variations in the stoichiometric composition used were Fe Sex Te1-x (Sex = 0,25 ; 0,5 ; 0,75) (Te1-x= 0,75 ; 0,5 ; 0,25.) and samples for each Fe1SexTex were taken for each Diameter = 5 mm. to determine. The raw material used contains purity of Fe (99.0%), Se (99.0%) and Te (99.9%). The process in making Monofilament FeSeTe superconducting wire is through 3 processes, namely closing the tube using the press method (PIST), heating at 700^0 C (FURNANCE) and reducing cross section diameter (ROLLING) after the characterization test (CRYOGENIC) and analyzing SEM (SCANING ELECTRON MICROSCOPY), XRD (X-RAY DIFFRACTION). Monofilament wire uses Cu pipes with a diameter of 6 mm and a length of 5mm totaling 3 pieces.} }
