Summary: | <p class="Els-Abstract-text">Ekstraksi pektin kulit buah naga dilakukan menggunakan metode <em>Microwave Assisted Extraction</em> (MAE) dengan variasi berat bahan (10, 15, and 20 gram) dan waktu ekstraksi (15, 20, and 25 minute). Ekstraksi dengan variasi berat bahan dilakukan pada waktu ekstraksi 25 menit dan daya 600 W, sedangkan ekstraksi dengan variasi waktu dilakukan pada berat bahan 10 gram dan daya 600 W. Pektin yang diperoleh dianalisis kadar pektinnya menggunakan uji Fourier Transform Infrared (FTIR) dan diproses menjadi edible film. Hasil penelitian menunjukkan bahwa yield pektin kulit buah naga dengan metode MAE lebih besar dibandingkan metode konvensional. Variasi berat bahan mempengaruhi yield pektin yang dihasilkan, semakin sedikit bahan yang digunakan dalam ekstraksi, semakin besar yield pektin kulit buah naga yang dihasilkan. Yield pektin terbesar (72 %) dihasilkan pada variasi berat 10 gram. Variasi waktu ekstraksi juga memberikan pengaruh terhadap yield pektin, semakin lama waktu ekstraksi semakin besar yield pektin kulit buah naga yang dihasilkan. Yield pektin terbesar dihasilkan pada waktu ekstraksi 25 menit. Pektin hasil ekstraksi dapat digunakan sebagai bahan edible film.</p><p class="Els-Abstract-text"> </p><p class="Els-Abstract-text"><span lang="IN">Extraction of pectin</span><span lang="IN">from</span> dragon fruit <span lang="IN">peel</span> is conducted using Microwave Assisted Extraction (MAE) method with the variation of the weight of the raw materials are 10, 15, and 20 gram and the time of the extraction are 15, 20 and 25 minutes.
