      Abstract
      Membran adalah selaput tipis bersifat semipermeabel diantara dua fasa yang berbeda. Fasa pertama disebut feed atau larutan pengumpan dan fasa kedua disebut permeate atau hasil pemisahan. Fungsi utama dari membran ialah sebagai lapisan semipermeabel yang dapat melewatkan dan menahan komponen tertentu dalam suatu campuran. Telah dilakukan penelitian untuk mengetahui mekanisme transport ion yang melewati membran bawang bombay dan bawang daun berdasarkan pengukuran sifat kelistrikan membran dengan meninjau pengaruh dari konsentrasi dan suhu. Sifat kelistrikan dapat dilihat dengan melakukan pengukuran konduktansi. Penentuan konduktansi membran dilakukan dengan cara meletakkan membran di dalam chamber yang diisi larutan elektrolit KCl variasi konsentrasi dan suhu. Semakin besar konsentrasi dan suhu larutan eksternal maka konduktansi membran meningkat. Pemberian konsentrasi 10 mM, 505 mM, 1 M, dan 1,205 M berpengaruh besar pada peningkatan nilai konduktansi.
       
      The membrane is a semipermeable thin membrane between two different phases. The first phase is called the feed or feed solution and the second phase is called the permeate or the separation. The main function of the membrane is as a semipermeable layer that can pass and hold certain components in a mixture. Research has been carried out to determine the ion transport mechanism through the membrane of onions and leeks based on the measurement of the electrical properties of the membrane by observing the effect of concentration and temperature. Electrical properties can be seen by measuring conductance. Determination of membrane conductance is done by placing the membrane in a chamber filled with KCl electrolyte solution with variations in concentration and temperature. The greater the concentration and temperature of the external solution, the increased membrane conductance. Giving concentrations of 10 mM, 505 mM, 1 M, and 1,205 M had a major effect on increasing the conductance value.
