PENURUNAN KADAR PROTEIN LIMBAH CAIR TAHU DENGAN PEMANFAATAN KARBON BAGASSE TERAKTIVASI (Protein Reduction of Tofu Wastewater Using Activated Carbon Bagasse)

doi: 10.22146/jml.18537
ABSTRAK Penurunan kadar protein limbah tahu telah dilakukan dengan pemanfaatan karbon Bagasse teraktivasi. Tujuan dari penelitian ini adalah untuk mengetahui kondisi optimum dari karbon teraktivasi NaOH dan H2SO4 dalam menurunkan kadar protein limbah cair tahu dan mengetahui jenis isoterm adsorpsi dari karbon aktif yang digunakan untuk menyerap protein limbah cair tahu. Hasil penelitian menunjukkan konsentrasi NaOH yang optimum untuk aktivasi karbon aktif 15%, massa optimum karbon bagasse teraktivasi NaOH adalah 2 g dan penurunan kadar proteinnya 71,95%, sedangkan massa optimum karbon bagasse teraktivasi H2SO4 adalah 1 g dengan penurunan kadar protein sebesar 38,19%. Waktu kontak optimum karbon bagasse teraktivasi NaOH dan H2SO4 adalah 12 jam. Adsorpsi protein oleh karbon bagasse teraktivasi NaOH mengikuti isoterm adsorpsi Langmuir dan Freundlich sedangkan karbon bagasse teraktivasi H2SO4 dominan mengikuti isoterm Freundlich. ABSTRACT The protein reduction of tofu wastewater using activated carbon from bagasse had been conducted. The purposes of this research were to analysis optimum condition of activated carbon bagsse using NaOH and H2SO4 for reduction protein in tofu wastewater, and analysis adsorption isotherm of activated carbon with protein. The result showed that optimum mass of carbon bagasse activated NaOH was 2 g with 71.95% protein reduction, while carbon bagasse activated H2SO4 has 1 g with 38.19% protein reduction. The optimum contact time between protein and activated carbon (with NaOH and H2SO4) was happened in 12 hours. Adsorption protein with carbon bagasse activated NaOH had followed Langmuir and Freundlich adsorption isotherm, while adsorption with carbon bagasse activated H2SO4 dominantlyhad followed Freundlich adsorption isotherm
