Abstract

Cellulose acetate is a derivative of cellulose that has high commercial value and is widely used in various industries such as textiles, plastics, and paints. This study aims to synthesize and analyze the characteristics of cellulose acetate derived from kapok fiber (Ceiba pentandra) using the solution process method. The synthesis process includes delignification, bleaching, activation, acetylation, and hydrolysis stages. The variables tested in this research were the volume of glacial acetic acid (8–40 mL) and the acetylation time (60–150 minutes). The analysis results showed that the highest acetyl content of 39.92% was obtained at an acetylation time of 90 minutes and an acetic acid volume of 40 mL, with a degree of substitution reaching 2.466, classified as cellulose diacetate according to the Indonesian National Standard (SNI). FTIR spectra confirmed the presence of characteristic functional groups of cellulose acetate, such as the carbonyl (C=O) and ester (C–O) groups from the acetyl group. This study demonstrates that kapok fiber is a potential raw material for producing high-quality cellulose acetate.

Abstract

Kegiatan pelatihan Pembuatan Eco-Enzyme sebagai Upaya Pengelolaan Sampah Organik Rumah Tangga ini dilakukan untuk meningkatkan pengetahuan kepada masyarakat, khususnya para ibu PKK, Desa Girirejo mengenai konsep eco-enzyme beserta manfaatnya bagi lingkungan. Kegiatan dilakukan melalui penyampaian materi dilanjutkan dengan praktik secara langsung oleh tim KKN diikuti oleh peserta. Kegiatan juga berlangsung dengan baik di Balai Desa Girirejo. Hasil kegiatan menunjukkan pemahaman dan kesadaran masyarakat yang semakin meningkat dalam memanfaatkan limbah organik menjadi bahan multifungsi, yaitu eco-enzyme. Hal ini dibuktikan dengan antusiasme peserta yang aktif dan partisipatif serta keterampilan mereka yang baik dalam proses praktik pembuatan eco-enzyme. Melalui kegiatan ini, masyarakat menjadi paham mengenai pengelolaan sampah organik yang baik serta membuka peluang pemanfaatannya melalui eco-enzyme yang bernilai ekonomi dan berkelanjutan.
