Abstract
Pengembangan biodiesel telah ditetapkan sebagai salah satu prioritas dalam Proyek Strategis Nasional (PSN) untuk mendukung ketahanan energi dan keberlanjutan lingkungan. Biodiesel merupakan bahan bakar nabati berbentuk ester metil asam lemak (Fatty Acid Methyl Ester/FAME) yang diproduksi melalui proses transesterifikasi minyak nabati atau lemak hewani. Selain menghasilkan biodiesel sebagai produk utama, proses ini juga menghasilkan gliserol (gliserin) sebagai produk samping sekitar 10% dari total biodiesel yang diproduksi. Namun, saat ini pemanfaatan gliserol masih terbatas sehingga memiliki nilai jual rendah. Oleh karena itu, pengolahan gliserol menjadi produk bernilai tinggi sangat diperlukan untuk meningkatkan efisiensi dan keberlanjutan industri biodiesel. Salah satu produk turunan dari gliserol adalah diasetin, yang diperoleh melalui reaksi antara gliserol dan vinil asetat dengan katalis Novozym® 435. Diasetin memiliki aplikasi luas, seperti aditif dalam industri semen dan cat, serta bahan dalam kosmetik. Selain itu, diasetin dapat berfungsi sebagai bioaditif untuk meningkatkan angka oktan bahan bakar minyak dan sebagai bahan baku pembuatan poliester biodegradable. Untuk memaksimalkan manfaat dari produk ini, pabrik diasetin direncanakan dibangun di Dumai, Riau dengan kapasitas produksi 55.000 ton/tahun dan target operasional pada 2029. Proses produksi diasetin terdiri dari tiga tahap utama, yaitu pre-treatment, reaksi, dan purifikasi, yang dirancang untuk menghasilkan produk berkualitas tinggi dan mendukung pengembangan industri hijau.

The development of biodiesel has been designated as a priority under the National Strategic Projects (PSN) to support energy security and environmental sustainability. Biodiesel is a biofuel in the form of Fatty Acid Methyl Ester (FAME), produced through the transesterification process of vegetable oils or animal fats. In addition to biodiesel as the primary product, the process also generates glycerol as a by-product, accounting for approximately 10% of the total biodiesel output. However, the current utilization of glycerol remains limited, resulting in low economic value. Therefore, the conversion of glycerol into high-value products is essential to enhance the efficiency and sustainability of the biodiesel industry. One promising derivative of glycerol is diacetin, which is produced through the reaction of glycerol with vinyl acetate using the catalyst Novozym® 435. Diacetin has diverse applications, such as an additive in the cement and paint industries and an ingredient in cosmetics. Additionally, it serves as a bio-additive to improve the octane rating of fuel and as a raw material for biodegradable polyester production. To maximize the potential of this product, a diacetin plant is planned for construction in Dumai, Riau, with a production capacity of 55,000 tons per year and targeted operational commencement in 2029. The production process consists of three main stages: pre-treatment, reaction, and purification, designed to ensure high product quality and promote the development of a green industry.
