Abstract
Pektin merupakan polisakarida alami yang memiliki kemampuan membentuk film yang baik serta bersifat biodegradable, sehingga berpotensi sebagai bahan baku terbarukan untuk pembuatan film biopolimer yang ramah lingkungan. Namun, film pektin murni memiliki sifat mekanik yang terbatas dan interaksi terhadap air yang kurang diinginkan, sehingga diperlukan modifikasi formulasi untuk memperoleh karakteristik yang sesuai dengan aplikasi tertentu. Penelitian ini bertujuan untuk mengkaji pengaruh pati jagung (maizena), pati tapioka, gliserol, dan xilitol terhadap sifat film berbasis pektin serta mengevaluasi hubungan antara variasi formulasi dan karakteristik film sebagai dasar pengembangan material kandidat healing patch. Film dibuat menggunakan metode solution casting dengan sembilan formulasi yang berbeda, kemudian dikarakterisasi berdasarkan ketebalan, kekuatan tarik, swelling, dan kelarutan. Hasil penelitian menunjukkan bahwa variasi formulasi menghasilkan karakteristik film yang berbeda-beda. Pati jagung cenderung meningkatkan kekuatan tarik dibandingkan pati tapioka, sedangkan pati tapioka memberikan karakteristik yang lebih baik terhadap interaksi film dengan air. Gliserol menghasilkan film yang lebih tebal disertai penurunan kekuatan tarik, sedangkan xilitol mampu mempertahankan bahkan meningkatkan kekuatan tarik pada formulasi tertentu sekaligus memberikan karakteristik interaksi terhadap air yang diinginkan. Ketebalan film berada pada kisaran 0,075–0,159 mm, kekuatan tarik 11,43–76,00 MPa, swelling 21,12–304,94%, dan kelarutan 1,97–6,98%. Secara keseluruhan, variasi formulasi menunjukkan adanya hubungan yang jelas dengan sifat film berbasis pektin, sehingga menghasilkan profil sifat fisik, mekanik, dan interaksi terhadap air yang berbeda pada setiap formulasi. Meskipun tidak terdapat satu formulasi yang menunjukkan kinerja terbaik pada seluruh parameter yang dievaluasi, formulasi pektin–pati tapioka (PT) menunjukkan keseimbangan yang paling baik antara swelling dan kelarutan, sehingga memiliki potensi terbesar untuk manajemen eksudat sebagai material kandidat healing patch. Temuan ini memberikan dasar ilmiah bagi pengembangan film berbasis pektin sebagai material kandidat healing patch serta mendukung pencapaian Sustainable Development Goals (SDGs), khususnya SDG 3 (Good Health and Well-being), SDG 9 (Industry, Innovation and Infrastructure), dan SDG 12 (Responsible Consumption and Production), melalui pengembangan material biopolimer terbarukan untuk aplikasi kesehatan, inovasi material, serta konsumsi dan produksi yang berkelanjutan.

Pectin is a natural polysaccharide with excellent film-forming ability and biodegradable properties, making it a promising renewable material for environmentally friendly biopolymer films. However, pure pectin films exhibit limited mechanical properties and undesirable interactions with water, necessitating formulation modifications to obtain characteristics suitable for specific applications. This study aimed to investigate the effects of maizena, tapioca starch, glycerol, and xylitol on the properties of pectin-based films and to evaluate the relationship between formulation variations and film characteristics as a basis for the development of candidate healing patch materials. The films were prepared using the solution casting method with nine different formulations and characterized in terms of thickness, tensile strength, swelling, and solubility. The results demonstrated that formulation variations produced distinct film characteristics. Maizena tended to improve tensile strength compared with tapioca starch, whereas tapioca starch provided characteristics more favorable for film water interaction. Glycerol produced thicker films accompanied by a reduction in tensile strength, while xylitol was able to maintain or even improve tensile strength in certain formulations while simultaneously providing desirable water-interaction characteristics. Film thickness ranged from 0.075 to 0.159 mm, tensile strength from 11.43 to 76.00 MPa, swelling from 21.12 to 304.94%, and solubility from 1.97 to 6.98%. Overall, formulation variations established a clear relationship with the properties of pectin-based films, resulting in distinct physical, mechanical, and water-interaction profiles for each formulation. Although no single formulation demonstrated superior performance across all evaluated parameters, the pectin tapioca starch (PT) formulation exhibited the most favorable balance between swelling and solubility, suggesting the greatest potential for exudate management as a candidate healing patch material. These findings provide a scientific basis for the development of pectin-based films as candidate healing patch materials and support the achievement of Sustainable Development Goals (SDGs) 3 (Good Health and Well-being), 9 (Industry, Innovation and Infrastructure), and 12 (Responsible Consumption and Production) through the development of renewable biopolymer materials for healthcare applications, material innovation, and sustainable consumption and production.
