| dc.description.abstract | Sintesis nanopartikel perak dengan metode kimia mempunyai beberapa kelemahan, diantaranya tidak ramah lingkungan. Rimpang tanaman Curcuma dapat menjadi alternatif agen pereduksi. Salah satu faktor yang berperan dalam tanaman Curcuma sebagai agen pereduksi adalah kandungan total fenoliknya. Senyawa fenol dapat bertindak sebagai agen pereduksi dalam reduksi logam menjadi nanopartikel logam. Tujuan penelitian ini untuk mengidentifikasi potensi rimpang Curcuma khususnya temu putih, temu hitam, temu kunci, temu giring, temu mangga, dan kurkumin sebagai agen pereduksi perak menjadi nanopartikel perak (AgNp) berdasarkan kandungan total fenolik rimpang tanaman tersebut dan kitosan sebagai agen penstabil AgNp. Karakteristik AgNp yang dianalisis meliputi ukuran partikel, polidispersitas (PdI), dan potensial zeta serta mekanisme kitosan sebagai agen penstabil pada AgNp. Kitosan dapat meningkatkan aktivitas biologis AgNp, kompatibilitas AgNp, dan dapat memodifikasi muatan permukaan AgNp sehingga dapat diaplikasikan secara lebih luas. | id |
| dc.description.abstract | The synthesis of silver nanoparticles by chemical methods has several disadvantages, including not being environmentally friendly. Curcuma rhizome can be an alternative natural reducing agent. One of the factors that play a role in Curcuma plants as reducing agents is the total phenolic content. Phenol compounds can act as reducing agents in the reduction of metal into metal nanoparticles. The purpose of this study was to identify the potential of Curcuma rhizome, especially white ginger, black turmeric, fingerroot, temu giring, mango ginger, and curcumin as a reducing agent for silver nanoparticles (AgNp) based on the total phenolic content of these plants rhizomes, and to study chitosan as a stabilizing agent for AgNp. The characterizations analyzed included particle size, polydispersity (PdI), and zeta potential as well as the mechanism of chitosan as a stabilizing agent in AgNp. Chitosan can increase AgNp biological activity, increase nanoparticle compatibility, and can modify the surface of AgNp so that they can be applied more widely. | id |
