Abstract

Daun kelor (Moringa oleifera) adalah bagian dari tumbuhan yang memiliki bentuk seperti daun dengan berbagai manfaat kesehatan dan gizi yang tinggi, serta terdapat kandungan vitamin, mineral, protein, dan senyawa bioaktif, serta memiliki sifat antioksidan dan antiinflamasi. Penelitian ini bertujuan untuk mempelajari ekstrasi, mengetahui keberadaan kandungan tannin pada daun kelor dan mengetahui model kinetika ekstraksi pada ekstrak yield daun kelor meggunakan metode Microwave Assisted Extraction (MAE). Proses ekstraksi daun kelor dilakukan dengan menggunakan pelarut etanol 96% dan menggunakan metode Microwave Assisted Extraction (MAE) dapat membantu memaksimalkan rendemen ekstraksi. Proses ekstraksi dilakukan dengan variasi daya 150 watt, rasio bahan terhadap pelarut 1:15 b/v dan waktu ekstraksi 2, 4, 6, 8, dan 10 menit. Hasil penelitian menunjukkan nilai rendemen tertinggi didapatkan pada waktu ekstraksi di menit ke 10 yaitu 10,25%. Model kinetika ekstraksi yang sesuai untuk mengekstraksi senyawa tanin dari daun kelor adalah orde 2, dimana nilai R2 lebih tinggi dibandingkan orde 1 dan nilainya hampir mendekati 1.

Abstract

Moringa oleifera leaves are known for their distinctive leaf shape and offer numerous health and nutritional benefits.They are rich in vitamins, minerals, proteins, and bioactive compounds and possess antioxidant and anti-inflammatoryproperties. This study aimed to explore the extraction process, identify the presence of tannin compounds in Moringa leaves, and determine the appropriate kinetic model for the extraction of Moringa leaf extract using the Microwave-Assisted Extraction (MAE) method. The extraction was performed using 96% ethanol as the solvent and the MAEtechnique, which is known to enhance extraction efficiency. Variables such as power (150 watts), a material-to-solventratio of 1:15 (b/v), and extraction times of 2, 4, 6, 8, and 10 minutes were tested. The results indicated that the highest yield was achieved after 10 minutes, with a value of 10.25%. The extraction time was extended at most 10 minutesdue to time limitations and diminishing returns as extraction time increased. The study concluded that the second-orderkinetic model (R² = 0.9897) was the most suitable for describing the extraction of tannin compounds from Moringa leaves,outperforming the first-order model with a value closer to 1.
