Abstract

The synthesis of biodiesel from the waste cooking oil was carried out using the catalyst from egg shell of purebred chicken with methanol as a solvent. Synthesis the biodiesel was prepared in two steps, there are esterification and transesterification. In esterification was conducted in mol ratio of methanol and waste cooking oil were 9:1, with H2SO4 as a catalyst. Transesterification with mol ratio methanol and waste cooking oil were 12:1, with CaO from egg shell of purebred chicken as a catalyst. CaO catalyst was yielded by calcinations egg shell of purebred chicken on 1000 ⁰C for two hours. Calcination product was characterized with X-RD to determine of CaO. Result of biodiesel was characterized based on 1H-NMR, FTIR, GC-MS, dan ASTM (American Standard Testing of Materials). Yielded of biodiesel theoretically was 40.298% and experiment was 36.779%. Main component that resulted there is methyl stearic (40.21%).

Abstract

Keberadaan tanaman mayang di daerah Maluku Tengah cukup banyak. Pada umumnya masyarakat setempat memanfaatkan tanaman mayang hanya sebagai bahan baku pembuatan minuman tradisional beralkohol yang dikenal dengan nama sopi. Alkohol yang terkandung dalam minuman sopi tersebut dapat ditingkatkan kadar alkoholnya dengan cara redestilasi, sehingga dapat dijadikan bahan baku dalam pembuatan produk hand sanitizer. Oleh karena itu tim dosen Jurusan Kimia FMIPA Universitas Pattimura melakukan pelatihan pembuatan produk hand sanitizer berbahan dasar hasil redestilasi sopi kepada para siswa dan guru di SMA Negeri 40 Maluku Tengah. Pelatihan yang telah dilakukan meliputi redestilasi sopi, dan perhitungan formula serta demo pembuatan hand sanitizer. Diharapkan kedepannya para siswa dan guru dapat membuat produk tersebut dan dapat melatih masyarakat setempat untuk turut memanfaatkan minuman sopi sebagai bahan untuk menghasilkan produk hand sanitizer yang memiliki nilai guna untuk menjaga kesehatan masyarakat.
