Abstrak – Joule-Thief adalah salah satu rangkaian listrik untuk konservasi  energi dengan menggunakan teknis medan elektromagnetik arus transien pada sebuah coil. Sirkuit ini dioperasikan menggunakan  sebuah MOSFET sebagai saklar untuk meregenerasi  tegangan dan arus listrik dalam satuan waktu kemudian disalurkan pada beban light emitting diode (LED). Dari hasil eksperimental, sel volta berbasis air laut dengan tegangan jepit 0.8V mampu mengaktifkan lampu LED dengan konfigurasi rangkaian serial. Hasilnya menunjukkan bahwa power transfer maksimum dari sirkuit Joule-thief sangat efektif sebagai pemasok daya beban 60 LED.

Abstract – Joule-Thief is one of the electric circuits for conservation energy by using electromagnetic field trancient current in a coil. This circuit is operated using a MOSFET as a switch to regenerating the voltage and current flowing along the coil. The electric current accumulates in the coil then in unity of time will be supplied to the light emitting diode (LED) load. From experimental results, water sea voltaic cells based with 0.8V clamp voltage are able to activate LED lights in serial circuit configurations. The results shown that power transfer joule-thief circuit is very effective capable of supplying LED up to 60 LEDs.
