Abstract
Poly-L-Lactic Acid atau disingkat PLLA merupakan termoplastik biodegradable turunan dari sumber daya terbarukan. Kebutuhan dunia akan plastik yang terus meningkat seiring dengan meningkatnya pencemaran lingkungan yang disebabkan oleh plastik. Hal ini membuat PLLA menjadi alternatif pengganti plastik petroleum-based untuk mengurangi pencemaran lingkungan. Untuk memenuhi kebutuhan bioplastik dalam negeri dan adanya peluang ekspor yang masih terbuka, maka dirancang pabrik PLLA dengan kapasitas 20.000 ton/tahun dengan memanfaatkan limbah tetes tebu yang dihasilkan oleh pabrik gula sebagai bahan baku. Pabrik direncanakan berdiri pada tahun 2020 di Lampung Tengah, Sumatera Selatan. Proses pembuatan PLLA dilakukan melalui tiga tahap, yakni proses produksi asam laktat, pemurnian asam laktat, dan polimerisasi asam laktat. Tahap produksi asam laktat dilakukan dengan proses fermentasi dengan menggunakan bakteri Lactobacillus delbrueckii subsp. delbrueckii selama 26 jam pada kondisi 42oC, tekanan atmosfir, dan pH 6,9. Tahap pemurnian dilakukan hingga asam laktat mencapai kemurnian 99% dalam kolom distilasi reaktif. Tahap polimerisasi asam laktat dilakukan dengan metode ring-opening-polymerization. Untuk mendirikan pabrik PLLA dari limbah tetes tebu ini diperlukan modal tetap (FCI) sebesar Rp 926.811.877.912,00 dan modal kerja (WCI) sebesar 92.681,187.791,00. Dari perhitungan analisa ekonomi didapatkan nilai Pay Out Time (POT) 5,13 tahun dengan Break Event Point (BEP) sebesar 45,6% dan Internal Rate of Returm (IRR) sebesar 13,19%.
