PENGARUH UMUR KAYU MANGIUM TERHADAP KUALITAS ARANG AKTIF

Abstract

Dalam tulisan ini dikemukakan mengenai hasil penelitian pembuatan arang aktif dari kayu Acacia mangium berdasarkan perbedaan umur dengan cara aktivasi uap kimia. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh umur kayu mangium dan konsentrasi bahan pengaktif terhadap hasil dan kualitas arang aktif. Proses pembuatan arang aktif dilakukan dalam retor baja tahan karat dengan pemanas listrik pada suhu 900ºC. Umur kayu mangium yang digunakan sebagai bahan baku adalah 4, 5, 6 dan 7 tahun dan sebagai aktivator digunakan larutan NH4CO3 dengan konsentrasi masing­masing 0,1; 0,25; 0,5; 0,75%. Kualitas arang aktif yang terbaik dihasilkan dari arang aktif yang dibuat dari kayu mangium umur 6 tahun dengan konsentrasi NH4C03 sebesar 0,10%. Rendemen yang diperoleh sebesar 37,19%, kadar air 12,74%, kadar abu 2,08%, kadar zat mudah menguap 14, 66%, kadar karbon terikat 183,28%. Daya serap terhadap iodium sebesar 1081,19 mg/g, benzena 29,39%, CHCL3 40,19%, metilin biru 199,23 mg/g dan luas permukaan sebesar 738,0 m2/g.
