    Abstract
    The purpose of this instruments determine the viscosity of a liquid using falling ball method and compared with the time interval. The test results show that the viscosity can be obtained by finding the speed of a ball falling monitored by the sensor LDR. Viscosity is proportional to the concentration of the solution. A solution that has a high concentration of high viscosity, because the concentration of the solution stated number of particles dissolved substances per unit volume. The more particles are dissolved, the friction between the particles will be higher and higher viscosity.
     
    Tujuan dari alat ukur ini untuk menetukan viskositas suatu cairan dengan menggunakan metode bola jatuh dan dibandingkan dengan interval waktu. Hasil pengujian menunjukkan bahwa viskositas dapat diperoleh dengan mencari kecepatan bola jatuh yang dimonitor oleh sensor LDR. Viskositas berbanding lurus dengan konsentrasi larutan. Suatu larutan yang memiliki konsentrasi tinggi akan memiliki viskositas yang tinggi, karna konsentrasi larutan menyatakan banyaknya partikel zat yang terlarut tiap satuan volume. Semakin banyak partikel yang terlarut, gesekan antar partikel akan semakin tinggi dan viskositasnya semakin tinggi.
