      Abstract
      Telah dilakukan pengukuran konduktansi listrik membran gelembung renang ikan patin dan ikan mas menggunakan sistem transpor ion. Hal ini secara umum bertujuan untuk mengetahui karakteristik konduktansi listrik membran tersebut akibat pengaruh faktor konsentrasi larutan KCl dan suhu. Hasil penelitian menunjukkan bahwa baik semakin tinggi konsentrasi maupun suhu yang digunakan, konduktansi listrik membran memiliki kecenderungan semakin meningkat. Memban gelembung renang ikan patin, konduktansi terendah sebesar 5,849 × 10-5 saat berada pada konsentrasi 0,1 mM dan suhu 286,8 K, sedangkan konduktansi tertinggi sebesar 6,543 × 10-4 S saat berada pada konsentrasi 120,69 mM dan suhu 325,8 K. Pada membran gelembung renang ikan mas, konduktansi terendah sebesar 9,016 × 10-6 S saat berada pada konsentrasi 0,1 mM dan suhu 286,8 K, sedangkan konduktansi tertinggi sebesar 2,09 × 10-3 S saat berada pada konsentrasi 100 mM dan suhu 328,8 K. Berdasarkan analisis ANOVA, faktor yang paling signifikan terhadap konduktansi listrik membran gelembung renang ikan patin adalah konsentrasi kemudian suhu dan pada membran gelembung renang ikan mas adalah konsentrasi diikuti oleh suhu, kuadarat dari konsentrasi, serta interaksi konsentrasi dan suhu. Nilai yang diprediksi dari persamaan regresi RSM ditemukan sesuai dengan yang diamati, menunjukkan bahwa persamaan regresi tersebut dapat digunakan untuk memprediksi respon.
       
      The electric conductance measurement of the swim bladder membrane of catfish and goldfish using the ion transport system has been carried out. In general, this aims to determine the electrical conductance characteristics of the membrane due to the influence of the KCl solution concentration and temperature. The results showed that both the higher the concentration and the temperature used, the electrical conductance of the membrane had a tendency to increase. In the swim bladder of catfish, the lowest conductance was 5,849 × 10-5 S when it was at a concentration of 0,1 mM and a temperature of 286,8 K, while the highest conductance was 6,543 × 10-4 S when it was at a concentration of 120,69 mM and temperature. 325,8 K. In the goldfish swim bladder membrane, the lowest conductance was 9,016 × 10-6 S when it was at a concentration of 0,1 mM and a temperature of 286,8 K, while the highest conductance was 2,09 × 10-3 S when it was at a concentration of 100 mM and a temperature of 328,8 K. Based on the ANOVA analysis, the most significant factor on the electrical conductance of the catfish swim bladder membrane was concentration then temperature and on the goldfish swim bladder membrane was the concentration followed by temperature, the square of the concentration, and the interaction. concentration and temperature. The predicted values of the RSM regression equation were found to be consistent with those observed, indicating that the regression equation can be used to predict responses.
