Abstract
Mikroalga dapat memberikan peluang besar untuk memenuhi sumber cadangan energi dunia. Proses ekstraksi mikroalga menjadi biodiesel perlu dikembangkan agar lebih efisien.Mikroalga jenis Chlorella vulgaris memiliki potensi menghasilkan lipid yang baik untuk dijadikan biodiesel. Dalam proses pembuatan biodiesel salah satu bagian yang penting adalah proses ekstraksi. Pada penelitian ini digunakan model perpindahan massa pada ekstraksi lipid mikroalga Chlorella Vulgaris dengan menggunakan Pelarut CXM (CO2-Expanded Methanol). Diberikan kontrol optimal pada model yang dipilih agar hasilnya lebih efisien. Metode kontrol optimal yang dipilih adalah LQR (Linier Quadratic Regulator) dengan meninjau volume pelarut sebagai variable kontrol. Kemudian dilakukan perbandingan hasil kontrol optimal yang terjadi. Hasil simulasi menunjukkan bahwa setelah diberikan kontrol, konsentrasi lipid dalam aliran pelarut meningkat sebesar 0.4175 kg/m3 dan konsentrasi lipid dalam partikel mikroalga sebesar 1711 kg/m3.

=======================================================
Microalgae can provide great opportunities to meet the world's energy reserves. Microalgae extraction process into biodiesel needs to be developed to be more efficient. Chlorella vulgaris type chlorella species have the potential to produce good lipids for biodiesel. In the process of making biodiesel one important part is the extraction process. In this study used mass transfer model on Chlorella Vulgaris microbial lipid extraction using CXM (CO2-Expanded Methanol) Solvent. Given optimal control on the selected model for more efficient results. The optimal control method chosen is LQR (Linear Quadratic Regulator) by reviewing the volume of solvent as control variable. Then do the comparison of optimal control result that happened. The simulation results showed that after control, the lipid concentration in the solvent flow increased by 0.4175 kg/m3 and the lipid concentration in the microalgae particles was 1711 kg/m3. Keywords - Biodiesel, Chlorella vulgaris, Extraction, Lipid Concentration, Volume of solvent. LQR (Linear Quadratic Regulator)
