Baterai logam udara merupakan sumber energi baru yang memiliki nilai energi yang tinggi. Komponen yang terdapat pada baterai logam udara yaitu elektroda (anoda, katoda) dan elektrolit. Anoda yang di gunakan pada penelitian ini adalah alumunium dan katoda udara yang digunakan adalah pemanfaatan abu boiler dari cangkang dan fiber dimana pada abu boiler ini berpotensi untuk menjadi bahan katoda udara. Penelitian ini dilakukan untuk mengetahui potensi dari abu boiler sebagai material baterai alumunium udara, dan untuk mengetahui pengaruh jenis elektrolit NaOH; HCl; NaCl, konsentrasi larutan elektrolit 1 M; 2 M; 3 M dan berat abu boiler terhadap perolehan nilai tegangan dan arus baterai. Metodologi penelitian ini meliputi persiapan anoda dari alumunium lalu pembuatan katoda udara dengan bahan baku abu boiler, lalu perakitan batrai dengan susunan berlapis yaitu alumunium, kertas saring, abu boiler dan larutan elektrolit kemudian di lakukan pengukuran kuat arus dan tegangan dengan alat multimeter. Hasil dari penelitian ini adalah pengaruh berat karbon aktif dan konsentrasi larutan elektrolit tidak mempunyai pengaruh yang signifikan terhadap perolehan tegangan dan arus, dan untuk pengaruh jenis elektrolit memiliki pengaruh dimana hasil tegangan dan arus berturut-turut paling tinggi di tunjukkan pada larutan elektrolit NaOH.
Kata Kunci : Baterai logam udara; baterai alumunium udara; abu boiler; elektrolit.
