Antosianin memiliki berbagai aktivitias biologis seperti efek antioksidatif, antiinflamasi, neuroprotektif, dan antifibrosis periduktal. Salah satunya umbi Myrmecodia pendens, diketahui mengandung antosianin. Untuk memperoleh antosianin dari umbi Myrmecodia pendens tersebut secara optimum perlu dilakukan ekstraksi dengan metode yang sesuai. Metode ekstraksi berbantu gelombang mikro (MAE) dipilih karena waktu ekstraksinya yang singkat, hemat pelarut, dan murah dibandingkan dengan metode ekstraksi konvensional. Metode permukaan respon (RSM) digunakan untuk merancang desain eksperimen dan menentukan kondisi optimum MAE dalam memperoleh kadar antosianin. Tujuan penelitian ini adalah untuk menentukan kondisi optimum MAE dalam memperoleh kadar antosianin dari umbi Myrmecodia pendens menggunakan RSM. Metode penelitiannya meliputi pembuatan desain eksperimen, persiapan sampel, ekstraksi dengan MAE, penentuan kadar antosianin menggunakan spektrofotometer UV/Vis, dan analisis data menggunakan RSM. Faktor dalam desain eksperimen ini antara lain konsentrasi pelarut, rasio, waktu, dan daya. Hasil analisis, kondisi optimum diperoleh dengan faktor konsentrasi pelarut etanol 80%, rasio sampel terhadap pelarut 1:8, waktu ekstraksi 3 menit, dan daya alat MAE 10%, dengan indeks desirability 0,877 dan kadar antosianinnya sebesar 3.807,31 mg/L ekuivalen sianidin-3-glukosida.</description><subject>Anthocyanins.</subject><identifier>20411903</identifier><source>http://lib.ui.ac.id/file?file=digital/2016-2/20411903-S60131-Nurul Fajry Maulida.pdf</source><recordID>20411903</recordID></dc>
