Abstract

Glucosamine is useful for overcoming joint disease or osteoarthritis. Glucosamine can be produced through synthesis involving carbon and amine. Carbon can come from plant derivatives that contain sugar, like coconut sap. While the amine branch can be derived from ammonium sulphate. This study aims to determine the effect of ammonium sulphate added as a precursor in the process of synthesizing glucosamine from coconut sap towards physiochemical characteristics of glucosamine. The research used a one-factor-randomized design with addition of six levels of ammonium sulphate, that are 1,5 M; 2M; 2,5 M; 3 M; 3,5 M and 4 M. The characterisation includes the glucosamine concentration, pH, solubility, colour, and loss on drying (LOD). The best treatment was selected by using the TOPSIS method. The results showed that the best treatment was the addition of a 3.5 M ammonium sulphate precursor compound which had a glucosamine content of 801.67 ppm; yield of 1.603%; pH 4.79; and LOD of 0.837%. The precursor concentration had significant effects on the yield of glucosamine synthesised from coconut sap. The higher of glucosamine content and the resulting yield indicate the efficiency of the treatment applied to the sample is higher.

Abstract

Produk sabun dapat diperoleh dari reaksi hidrolisis asam lemak dengan basa (alkali). Salah satu sumber asam lemak yang biasa ditemukan dalam kehidupan sehari-hari adalah minyak goreng. Sisa minyak goreng bekas ada kecenderungan dibuang langsung ke lingkungan sekitar dan hal ini bisa menjadi limbah ke lingkungan sekitar. Kegiatan ini bertujuan untuk mengedukasi siswa sebagai agen transfer edukasi pada masyarakat tentang bahaya penggunaan minyak goreng secara berulang dan membantu memberikan solusi agar minyak jelantah dapat digunakan kembali dalam berbagai kondisi, termasuk pembuatan sabun cuci padat. Pengolahan limbah minyak jelantah menjadi sabun padat dilakukan kepada siswa/i kelas XI dan XII MIPA SMAN 9 Malang sebagai bentuk edukasi dalam mengurangi dampak buruk limbah minyak jelantah bagi lingkungan dan kesehatan. Berdasarkan hasil kegiatan pelatihan yang dilakukan, lebih dari 82% siswa/i SMAN 9 Malang memahami dan menerima materi pembuatan sabun padat berbahan dasar minyak jelantah dengan baik.
