Ringkasan Keahlian

Maisari Utami, dari Departemen Kimia Fakultas Sains, mengembangkan keahlian riset yang berfokus pada kimia material dan katalisis hijau untuk remediasi lingkungan dan energi terbarukan. Dalam lima tahun terakhir, risetnya didominasi oleh sintesis nanokomposit ramah lingkungan menggunakan ekstrak tumbuhan, seperti ekstrak kulit manggis dan kulit pisang, untuk menghasilkan material multifungsi. Publikasi mutakhirnya menonjolkan pengembangan TiO2/rGO dan Ag/TiO2/rGO sebagai agen antibakteri dan pelapis swa-bersih, serta pemanfaatan CQDs/TiO2 dari limbah kulit pisang untuk degradasi ibuprofen. Ia juga aktif merancang katalis heterogen dari ekstrak bunga rosella untuk produksi biodiesel dari minyak jelantah, dan mengubah limbah sekam padi menjadi adsorben Fe3O4/biochar untuk logam berat. Pergeseran tematik terlihat dari fokus awalnya pada katalis asam padat tersulfatasi untuk hidrokracking minyak sawit dan plastik menjadi biofuel, yang kini diperluas ke arah fotokatalisis dan adsorpsi polutan farmasi serta zat warna menggunakan material berbasis graphene dan oksida logam. Objek kajiannya meliputi degradasi zat warna Rhodamin B dan Congo red, serta pengolahan limbah batik. Metode sintesis hijau dan karakterisasi material canggih menjadi ciri khas risetnya, dengan arah mutakhir pada aplikasi lingkungan dan energi yang berkelanjutan.
