ABSTRAKBuah delima (Punica granatum L.) secara empiris digunakan untuk mengobati masalah gigi dan mulut seperti sariawan. Pengembangan obat sariawan berbasis herbal dengan bentuk sediaan patch dilakukan untuk mempertahankan waktu kontak antara zat aktif dengan bagian sariawan. Polivinilpirolidon (PVP) digunakan sebagai polimer karena sifatnya mukoadhesif sehingga mampu berikatan pada mukosa mulut. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan PVP sebagai polimer mukoadhesif terhadap karakteristik fisik sediaan patch yang mengandung ekstrak kulit buah delima (EKBD). EKBD diperoleh dengan metode maserasi. Konsentrasi EKBD yang digunakan adalah 5% dan 10%. Sedangkan konsentrasi polimer PVP yang digunakan yaitu 30,29%, 33,04, 48,75%, dan 65,5%. Patch selanjutnya akan di evaluasi fisik yang meliputi keseragaman bobot dan dimensi ketebalan, pH permukaan, swelling, daya lekat, dan waktu lekat. Hasil menunjukkan bahwa patch yang mengandung ekstrak 10% dengan tambahan polimer konsentrasi 30,29% memiliki sifat yang cukup elastis disbanding dengan konsentrasi 48,75% dan 65,5%. Sedangkan uji evaluasi fisik menghasilkan keseragaman bobot dan dimensi yang seragam, pH 6,63, rata-rata indeks swelling 40,69% ± 16, dan rata-rata daya dan waktu lekat 13,50 ± 11,6. Dengan demikian dapat disimpulkan bahwa konsentrasi PVP terbukti berpengaruh pada sifat fisik patch yang dihasilkan. Kata kunci : Polivinilpirolidon; Ekstrak Kulit Buah Delima; Patch.ABSTRACTPomegranate (Punica granatum L.) is empirically used to treat dental and mouth problems such as reccurent aphthous stomatitis (RAS). The development of RAS  therapy based on herbal with patches dosage forms is carried out to maintain the contact time between the active substance and the RAS. Polyvinylpyrrolidone (PVP) is used as a polymer because it is mucoadhesive, so it can bind to the oral mucosa. Aimed to determine the effect of the use of PVP as a mucoadhesive polymer on the physical characteristics of patches preparations containing pomegranate peel extract (PPE). PPE was obtained by maceration method. The PPE concentration used were 5% and 10%. PVP concentration used were 30.29%, 33.04%, 48.75%, and 65.5%. The patches properties such as uniformity of thickness, pH, swelling index, tensile and mucoadhesive strength. The results showed that patches containing 10% extract and PVP concentration of 30.29% had sufficient elastic properties compared to both concentration. While the physical evaluation test obtained uniform weights and dimensions that are uniform, pH 6.63, the average swelling index is 40.69% ± 16, and the tensile and mucoadhesive strength is 13.50 ± 11.6. Altogether, the concentration of PVP is proven to affect the physical properties of the resulting patch.Key word : Polyvinylpyrrolidone; Pomegranate Peel Extract; Patch.
