چکیده
Penelitian ini bertujuan untuk menghitung kadar selulosa dan glukosa dari kulit kopi arabika dengan mengekstraksi menjadi sehingga didapatkan persen yield sebesar 27,36% serta dilakukan karakterisasi yang diperoleh melakukan uji XRD didapat kristalinitasnya 63,76%. Kemudian dihidrolisis menggunakan katalis asam yaitu H2SO4 memvariasikan konsentrasi 8%, 10%, 12% suhu pemanasannya 80oC, 90oC, 100oC dalam waktu 4 jam diuji alat Refraktometer Brix. Dari hasil analisa tertinggi pada 10% 8% bukan 8%. Sedangkan kenaikan terdapat 80oC 95,4%, hal tersebut dipengaruhi oleh pemanasan semakin rendah persentase tinggi.
