Abstract

Vinegar wood is a mixture of solutions and dispersions of wood smoke from the pyrolysis. Pyrolysiswas doneat temperature of300oCfor 8hours and thesnake headfishpreservation processwas done bysoakingat vinegar woodconcentrationof 25%, 50% and 75% for 5minutes. Furthermorethe moisture of snake headfish was decreased before stored insealedjarsfor storage time during 1week, 2 weeksand 3weeks.The results showedthat therelative concentration ofphenol, aceticacid and carboxaldehydein coconut shellvinegar wood respectively by 21,65%; 47,90% and 4,54%.

Abstract

Pencemaran air oleh logam berat mangan (Mn) merupakan masalah serius di berbagai wilayah perairan. Salah satu metode yang efektif untuk menurunkan konsentrasi logam berat ini adalah melalui proses adsorpsi menggunakan karbon aktif. Penelitian ini memanfaatkan limbah sawi putih (Brassica pekinensia L.) sebagai bahan baku karbon aktif yang dihasilkan melalui pirolisis pada suhu 400 °C selama 1 jam, kemudian diaktivasi menggunakan larutan HCl 1N. Pengaruh variasi waktu kontak (0, 30, 60, 90, dan 120 menit) dan massa adsorben (0,2–1,0 gram) terhadap efisiensi dan kapasitas adsorpsi ion Mn dianalisis. Hasil penelitian menunjukkan bahwa karbon aktif memiliki kadar air 11,09%, sesuai standar SNI 06-3730-1995. Waktu kontak optimum untuk adsorpsi ion Mn adalah 90 menit, dengan efisiensi 64,7% dan kapasitas adsorpsi 6,47 mg/g. Variasi massa adsorben optimum 1,0 gram menghasilkan efisiensi tertinggi 68,37% dan kapasitas adsorpsi 5,12 mg/g. Hasil ini menunjukkan bahwa karbon aktif dari limbah sawi putih memiliki potensi yang baik sebagai adsorben untuk penyerapan ion logam Mn.
