Abstract

Tongkol jagung kering biasanya menjadi limbah dan dibakar begitu saja yang tentunya akan mengakibatkan cemaran lingkungan. Kondisi ini dapat menjadi salah satu motivasi untuk memproduksi bahan yang bernilai tambah dari limbah tongkol jagung untuk dijadikan arang aktif. Arang aktif merupakan arang yang telah ditingkatkan daya adsorpsinya dengan proses karbonisasi atau pemanasan dan proses aktivasi. Penelitian ini bertujuan untuk mengetahui pengaruh waktu aktivasi arang aktif tongkol jagung terhadap adsorpsi ion Pb2+. Proses pembuatan arang aktif dilakukan menggunakan aktivator NaOH 1,75%. Arang aktif dibuat dengan memvariasikan waktu aktivasi yaitu 30, 60, 90, 120, 150, 180, dan 210 (menit). Waktu aktivasi maksimum yang diperoleh yaitu pada menit ke-150 dengan daya adsorpsi sebesar 0.7146 mg/g. Mutu arang yang diperoleh dapat ditinjau dari kadar air dan kadar abu yang dihasilkan yaitu kadar air sebesar 14,28 % dan kadar abu sebesar 8,11%. Standar mutu arang aktif yang ditetapkn oleh SNI 06-3730-95 yaitu kadar air sebesar 15% dan kadar abu sebesar 10%.

Abstract

Empty Oil Palm Bunches (EOPB) are waste products from palm oil mills, the waste is produced in large quantities, but most palm oil mills have not utilized this waste product adequately. There are several contents of EOPB, namely cellulose, hemicellulose and lignin, each of which has economic value so that it can be utilized further. One significant opportunity is that cellulose in EOPB will be converted into glucose or bioethanol. Bioethanol is one of the options in supporting the availability of renewable energy resources. The bioethanol production process consists of initial pretreatment, hydrolysis, fermentation and purification. The delignification process of Empty Oil Palm Bunches (EOPB) using physical and chemical pretreatment can break down lignin and hemicellulose so that cellulose can be converted into glucose in bioethanol production. The pretreatment procedure with H2SO4 solvent is used to increase cellulose content. The purpose of this study was to determine how different concentrations of H2SO4 affect the amount of cellulose in the EOPB pretreatment process. Additional studies on bioethanol can be done with this cellulose content. There is an experimental component in this study, namely through direct observation and testing of materials containing different concentrations of H2SO4, namely 3%, 5%, and 7%, data were collected through laboratory experiments. The cellulose content for 0% H2SO4 concentration was 16.15%, 3% H2SO4 was 30.00%, 5% H2SO4 was 36.35%, and 7% H2SO4 was 41.09% indicating that the H2SO4 solvent can increase the cellulose content.
