PERLAKUAN HIDROLISIS BASA PADA CAMPURAN ECENG GONDOK DAN KULIT KOPI TERHADAP PRODUKSI BIOGAS LIMBAH CAIR PENGOLAHAN KOPI
No full textBerdasarkan penelitian yang telah dilakukan, maka dapat disimpulkan
sebagai berikut.
1. NaOH mampu menghidrolisis eceng gondok dan kulit kopi. Semakin
tinggi konsentrasi NaOH, maka semakin besar pula proses perenggangan
ikatan kuat pada lignin, sehingga proses hidrolisis pada biogas lebih
mudah.
2. Kombinasi terbaik berdasarkan 4 perlakuan adalah pada eceng gondok dan
kulit kopi yang dihidrolisis, yang menghasilkan nilai terbaik berdasarkan
efisiensi penanganan limbah.
3. Produksi biogas yang terbaik terjadi pada R4 dengan bahan isian
campuran kulit kopi dan eceng gondok yang sama sama dihidrolisis yaitu
dengan tekanan gas sebesar 1,55 g/cm
Reduksi Bahan Organik Kulit Kopi dan Eceng Gondok Terhidrolisis Menggunakan Proses Anaerobik
No full textCoffee pulp and water hyacinth are a biomass source that can be used to feeding material for biogas production as energy an anaerobic digester. But coffee pulp and water hyacinth contain lignin. The Alkaline or base hydrolysis is a method of the solving chemical structure of lignin compounds using a strong acid and base. The focus of research investigated the base hydrolysis with NaOH in coffee pulp and water hyacinth an anaerobic process for organic material reduction. The research design in laboratory conduct of organic materials reduction on coffee pulp and water hyacinth used Completely Random Design (CRD). Anaerobic treatments were without hydrolysis (H1), only the coffee pulp with hydrolysis (H2), only water hyacinth with hydrolysis (H3) and all with hydrolysis (H4). The highest NaOH concentration for lignin reduction on the base hydrolysis was 60 ppm. The analysis of variants with significantly (p<0.05) showed all treated differently. Anerobic treatment of the coffee pulp and water hyacinth (H4) had the highest value organic material reduction. The efficiency of organic material reduction i.e. C/N, BOD and COD was in sequence namely 64.22 ± 0.02; 75.23 ± 0.02 dan 52.55 ± 0.04
