Sintesis bahan superkonduktor BPSCCO-2223 telah dilakukan  dengan variasi
doping Pb 
o
C. Sintesis dilakukan dengan metode reaksi padatan 
o
C selama 10 jam, dan sintering dilakukan pada suhu 855
C selama 20
jam. Hasil penelitian menunjukkan bahwa peningkatan doping Pb dalam sampel
dapat meningkatkan fraksi volume BPSCCO-2223 dan menurunkan impuritas.
Berdasarkan analisis pola XRD didapatkan nilai fraksi volume BPSCCO-2223
yang paling tinggi adalah 62.06%  pada doping Pb 0.4. Sedangkan fraksi volume
BPSCCO-2223 terendah pada sampel dengan doping Pb 0.0 yaitu 42.14%.
Derajat orientasi pada sampel tanpa doping Pb yaitu 38.51%, nilai derajat
orientasi menurun pada sampel dengan doping Pb 0.1 menjadi 21.81%, namun
kemudian derajat orientasi akan mengalami peningkatan seiring dengan
pertambahan doping Pb 
Kata kunci: variasi doping Pb, fraksi volume, derajat orientasi, impuritas, fase

ABSTRACT

The synthesis of BSCCO-2223 superconducting material with varians of doping
Pb 
o
C has been done by solid state reaction method. The varians of doping Pb
was used for the research are 0.0, 0.1, 0.2, 0.3, and 0.4. Variation was carried out
to determine the effect of doping Pb on phase formation superconducting material
of BPSCCO-2223 that views based on volume fraction, the degree of orientation
and impurities. Calcination was executed for 10 hours at temperature of 800
C
and sintering for 20 hours at temperature of 855
o
C. Result of research shows the
increase of doping Pb in the sample could increase volume fraction of BPSCCO2223
and
decrease

impurity. Based on the XRD pattern analysis obtained olume
fraction value of BPSCCO-2223 that is relatively high is 62.06% on doping Pb
0.4.  The lowest volume fraction is 42.14% on doping Pb 0.0. The degree of
orientation in the sample without doping Pb is 38.51%, the value of degrees of
orientation decreases in the sample with doping Pb 0.1 to 21.81%. Then the
degree of orientation will increase along with the increase of doping Pb
