ANALISIS KEAUSAN, KOEFISIEN GESEK DAN KONDUKTIVITAS TERMAL KAMPAS REM TROMOL PADA SEPEDA MOTOR BERBAHAN KOMPOSIT KULIT KOPI DAN MgO

Peningkatan limbah kulit kopi akan menimbulkan dampak buruk bagi lingkungan jika tidak dikelola dengan baik. Salah satu cara dalam mengurangi limbah kulit kopi yaitu dengan memanfaatkan limbah kulit kopi sebagai bahan campuran dalam pembuatan kampas rem. Pembuatan kampas rem dilakukan dengan variasi komposisi dengan resin epoxy sebagai variable tetap serta kulit kopi dan MgO sebagai variable bebasnya dimana variasinya 40%:20%, 30%:30%, 20%:40%. Kemudian sampel kampas rem dilakukan pengujian keausan, koefisien gesek dan konduktivitas termal. Dari pengujian tersebut didapatkan hasil terbaik pada keausan kering dan basah pada variasi komposisi kulit kopi 20% dengan nilai 6,615 x 10-4 mm2/kg.m.dan 4,760 x 10-4 mm2/kg.m, pada pengujian koefosoen gesek dan konduktivitas termal mendapatkan nilai terbaik pada komposisi kulit kopi 40% dengan nilai 0,58666667 dan 0,1569145 ð‘Š/ð‘š.áµ’K
