Penelitian ini bertujuan untuk mensintesis dan mengkarakterisasi ZIF-67, mengenkapsulasi KR ke dalam ZIF-67, serta mengkaji karakteristik material KR@ZIF-67 menggunakan FTIR, XRD, dan UV-Vis DRS. ZIF-67 berhasil disintesis dengan rendemen sebesar 38,7%, sedangkan material KR@ZIF-67 disintesis melalui metode in situ encapsulation dengan rendemen sebesar 20,63% dan efisiensi enkapsulasi sebesar 2,53%. Karakterisasi FTIR menunjukkan terbentuknya ikatan Co–N serta keberadaan gugus C=O yang berasal dari KR. Analisis XRD mengonfirmasi bahwa struktur kristal ZIF-67 tetap terjaga setelah proses enkapsulasi. Sementara itu, hasil UV-Vis DRS menunjukkan peningkatan intensitas serapan pada sekitar 387 nm yang merupakan karakteristik serapan KR. Hasil penelitian ini mengindikasikan bahwa KR berhasil terenkapsulasi ke dalam ZIF-67 tanpa mengubah struktur kristal material tersebut</mods:abstract><mods:classification authority="lcc">QD Chemistry</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8601">2026-05</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Universitas Negeri Padang;Kimia FMIPA UNP</mods:publisher></mods:originInfo><mods:genre>Thesis</mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_eprint_47847"><mets:rightsMD ID="rights_eprint_47847_mods"><mets:mdWrap MDTYPE="MODS"><mets:xmlData><mods:useAndReproduction>
