Abstract


Modul thermoelectric merupakan alat konversi energi yang mengubah perbedaan selisih suhu menjadi listrik secara langsung, melalui prinsip efek seebeck. Thermoelectric memiliki keuntungan mengubah listrik secara langsung dan thermoelectric banyak digunakan di beberapa aplikasi teknik, dan saat ini banyak negara yang mulai memproduksi, mengembangkan dan menjual produk modul thermoelectric secara komersial. Tujuan penelitian ini adalah untuk menginvestigasi kinerja luaran tegangan terbuka, koefisien seebeck, tegangan tertutup, arus, dan daya dengan menggunakan pemanas heater dan pendingin air pada tipe modul thermoelectric  tipe TEC 12706, TEC 12715, dan TEG SP 1848 27145 yang dijual secara komersial di Indonesia. Penelitian dilakukan dengan menempatkan modul thermoelectric pada penjepit screw dengan tekanan 1 Mpa. Penelitian dilakukan dalam 2 kali pemanasan, percobaan pertama pemanasan dilakukan tanpa menggunakan beban luaran, dan percobaan kedua pemanasan dilakukan menggunakan beban luaran lampu 4,8 VDC 0,5 A. Sistem pemanasan menggunakan plat heater dengan suhu maksimal 150-151 °C dan sistem pendingin menggunakan water block dengan laju aliran air 150 l/jam secara konstan. Hasil penelitian menunjukkan keluaran listrik tertinggi diperoleh pada modul thermoelectric tipe TEG SP 1848 27145, di ikuti TEC 12715, dan TEC 12706. Kinerja keluaran modul thermoelectric tersebut dipengaruhi oleh nilai koefisien seebeck, dimana semakin tinggi nilai koefisien seebeck maka akan menghasilkan keluaran listrik yang semakin tinggi.
