Air Limbah Susu, C. vulgaris, Biodiesel, MikroalgaAbstrak
Dalam penelitian ini, dilaporkan metode untuk memperoleh biodiesel generasi ketiga dari Chlorella vulgaris (C. vulgaris) yang dibudidayakan dalam air limbah susu. Lipid diambil dari biomassa, dan biodiesel diproduksi melalui transesterifikasi. Biodiesel dievaluasi berdasarkan standar ASTM dan EN, termasuk densitas, viskositas, nilai kalor, dan titik nyala. Kromatografi gas digunakan untuk menentukan kandungan, komposisi, dan jenis ester metil asam lemak. Hasil penelitian menunjukkan hasil biodiesel sebesar 93% dengan komposisi 33% jenuh, 28% tak jenuh tunggal, dan 37% tak jenuh ganda. Uji mesin dilakukan untuk memantau emisi CO, CO₂, NOx, dan asap, serta menilai kinerja biodiesel. Temuan menunjukkan bahwa C. vulgaris yang dibudidayakan dalam limbah susu dapat digunakan untuk memproduksi biodiesel generasi ketiga. Metode yang diusulkan memanfaatkan limbah air susu dan mungkin dapat menjadi pengganti yang tepat untuk produksi biodiesel dan pembuangan air limbah.
