For example, sodium carboxymethyl cellulose (Na-CMC) is still a major import. Na-CMC is extensively used in the pharmaceutical industry as a thickening, stabilizing, emulsifying, tablet binding, and base gel. Na-CMC is synthesized from cellulosic natural products, such as durian peels, which are generally organic wastes. This study aims to utilize durian peel waste as a resource to produce Na-CMC that complies with the monographs of pharmaceutical excipients. In this research, the dried durian peel waste of losan-semoyo variety from Kediri Regency, East Java was used. Furthermore, the optimization of the extraction method was conducted by using Box-Behnken design method. The independent variables were temperature 60-100°C, time 2-6 hours, and NaOH concentration 5-15%. The optimum condition of the extraction method can produce the highest cellulose content of 78% and yield of 40.45% at 10.164% NaOH, 60°C, and 2 hours incubation. The synthesis of Na-CMC through alkalization and carboxymethylation steps produced a yield of 96.54% with a purity of 95%. The characterization of Na-CMC powder had a yellowish-white color, forming a colloidal solution in water with a pH of 7.33, a loss on drying of 8%, a sodium content of 8.18%, and a degree of substitution value of 0.805. In conclusion, Na-CMC prepared from losan-semoyo durian peel waste had similar properties to commercial Na-CMC according to the results of FTIR, SEM, XRD, and DSC instruments.

Penelitian ini menggunakan sampel limbah kulit buah durian varietas losan-semoyo yang diperoleh dari Kabupaten Kediri, Jawa Timur. Selanjutnya optimisasi metode ekstraksi menggunakan metode Box-Behnken Design. Variabel bebas menggunakan suhu 60-100°C, waktu 2-6 jam, dan kosentrasi NaOH 5-15%. Kondisi optimum dari metode ekstraksi dengan kombinasi NaOH 10,164%, suhu 60°C dalam waktu 2 jam dapat menghasilkan kadar selulosa 78?n rendemen 40,45%. Sintesis CMC-Na melalui tahap alkalisasi dan karboksimetilasi menghasilkan rendemen sebanyak 96,54?ngan kemurnian 95%. Karakterisasi serbuk CMC-Na berwarna putih kekuningan, membentuk larutan koloidal dalam air dengan pH 7,33, susut pengeringan 8%, kadar natrium 8,18%, dan nilai derajat substitusi 0,805. Hasil akhir menyatakan bahwa CMC-Na yang dihasilkan dari kulit buah durian losan-semoyo memberikan karakteristik yang sama dengan CMC-Na komersial berdasarkan hasil uji menggunakan instrumen FTIR, SEM, XRD dan DSC.
