Membran nanofiber berbasis polyvynil alcohol (PVA) yang dimodifikasi dengan ekstrak daun pepaya (Carica papaya L., CLE) dan daun sirsak (Annona muricata L., ALE) pada konsentrasi ekstrak 3%, 4%, dan 5% telah berhasil disintesis menggunakan teknik elektrospinning. Evaluasi karakteristik fisika-biokimia membran dilakukan dengan analisis karakterisasi FTIR, SEM, XRD, dan uji antibakteri terhadap P…
Research has been carried out on Fe(III)-IIPs (Ion Imprinted Polymers) using the cooling-heating method, with a cooling process (cooling) for 1 hour and a heating process (heating) with a constant temperature of 75°C for 7 hours. The formation of Fe(III)-IIPs cavities was influenced by variations in extraction time (18 and 12 hours) and the number of repetitions performed (7 and 10 repetitions…
