    Abstract
    Bahan superkonduktor BPSCCO non-dopan dan dopan Mx (M = Mg, Na, dan Ce dengan x = 5% dan 15%) dengan metode sol-gel berhasil dibuat. Namun setelah melalui uji Cryogenic Magnetic yang menghasilkan bahan superkonduktor dengan Tc-zero hanya BPSCCO non-dopan dan dopan Mg dan Ce. Dimana BPSCCO dengan dopan Mg 15% memiliki harga Tc-zero tertinggi yaitu pada suhu 77 K dengan fraksi volume 77.27% melalui uji XRD, sedangkan bahan superkonduktor yang memiliki harga Tc-zero terendah yaitu bahan superkonduktor dengan dopan Ce 15% pada suhu 72 K dan memiliki fraksi volume 52.62%. Bahan superkonduktor BPSCCO dengan dopan Na tidak berhasil mencapai Tc-zero (Nol resistansi), hanya mampu mencapai resistansi 3.77 x 10-2 Ohm pada suhu 69K
     
    The BPSCCO non-dopant and dopant Mx superconducting materials (M = Mg, Na, and Ce with x = 5% and 15%) with the sol-gel method were successfully made. But after going through the Cryogenic Magnetic test which produces superconducting material with Tc-zero only BPSCCO is non-dopant and dopant Mg and Ce. Where BPSCCO with 15% Mg dopant has the highest Tc-zero price that is at 77 K with a volume fraction of 77.27% through XRD test, while superconducting material has the lowest Tc-zero price that is superconductor material with Ce 15% dopant at 72 K and has a volume fraction of 52.62%. BPSCCO superconductor material with dopant Na failed to achieve Tc-zero (Zero resistance), only able to achieve resistance 3.77 x 10-2 Ohm at 69K
