BAMBANG ARIFIN %O Frida Agung Rohmadi, M.Sc %T SISTEM DETEKSI MINYAK GORENG YANG TELAH DIPAKAI MENGGORENG DAGING BABI BERBASIS LED DAN PHOTODIODA %X The research on detection system of cooking oil that has been used for frying pork based on LED and photodiode. The research aims to create dan to test a detection system of cooking oil that has been used for frying pork based on LED and photodiode. This research was conducted in three phases: characterization of photodiode, creating and testing a detection system of cooking oil that has been used for frying pork based on LED and photodiode. The result showed that the photodiode has transfer function V = 0,3358e0,026I; input and output relationship with correlation coefficient r = 0,98; sensitivity 0,026 volt/lux; and reapetability 99,58%. The success rate of detection system implementation on test samples was 100%. %K cooking oil, pork, photodiode %D 2015 %I UIN SUNAN KALIJAGA YOGYAKARTA %L digilib16503
