Abstract
Palm midrib contain 89.63 % of cellulose. Cellulose is the main raw material synthesis of carboxy methyl cellulose (CMC). The purpose of this research was to determine the optimum conditions of carboxy methyl cellulose (CMC) synthesis from palm midrib. In this research, the concentration of NaOH, NaMCA weight, and the temperature of carboxymethylation reaction were examined. The response optimized on the CMC was the degree of substitution (DS). The optimum conditions of CMC synthesis from palm midrib cellulose was obtained from 10 % of NaOH, 4.57 g of NaMCA, and the reaction temperature of 46.59 °C. Response Surface Methodology calculation showed that CMC with optimum condition had the degree of substitution (DS) value of 0.83, while in the verification test the DS value was 0.75.   ABSTRAK Pelepah kelapa sawit mempunyai kandungan selulosa sebesar 89,63 %. Selulosa merupakan bahan baku utama sintesis karboksi metil selulosa (CMC). Tujuan dari penelitian ini adalah untuk mengetahui kondisi optimum sintesis CMC dari pelepah kelapa sawit. Faktor yang diteliti pada penelitian ini adalah konsentrasi NaOH, berat NaMCA, dan suhu reaksi karboksimetilasi. Respon yang dioptimasi pada CMC yang dihasilkan adalah derajat substitusi (DS). Kondisi optimum sintesis CMC dari selulosa pelepah kelapa sawit didapatkan dengan konsentrasi NaOH 10 %, berat NaMCA 4,57 g, dan suhu reaksi 46,59 °C. Hasil dari perhitungan RSM menunjukkan CMC dengan kondisi optimum memiliki nilai DS sebesar 0,83 sedangkan uji verifikasi menunjukkan nilai DS sebesar 0,75.
