Abstract

Pada penelitian ini dilakukan green synthesis komposit CuFe2O4@MnO2 menggunakan ekstrak daun kersen (Muntingia Calabura L.) Komposit CuFe2O4@MnO2 digunakan untuk mendegradasi zat warna procion red. Komposit hasil sintesis dikarakterisasi menggunakan XRD, SEM-EDS, VSM dan UV-Vis DRS. Hasil karakterisasi XRD menunjukkan adanya puncak tertinggi pada sudut 2θ = 36,09o dengan ukuran kristal sebesar 66 nm. Hasil karakterisasi SEM-EDS menunjukkan morfologi permukaan CuFe2O4@MnO2 tersusun dari partikel nano yang terakumulasi membentuk struktur bola, unsur penyusunnya berupa Mn (54,14%), O (29,14%), Fe (10,94%) dan Cu (5,79%). Hasil SEM mapping mengkonfirmasi adanya penyebaran unsur Mn dan O di permukaan CuFe2O4. Hasil VSM menunjukkan nilai magnetisasi saturasi komposit sebesar 16,75 emu/g. Nilai band gap energi komposit CuFe2O4@MnO2 sebesar 1,37 eV dan nilai pHpzc komposit sebesar 7,4. Kondisi optimal fotodegradasi zat warna procion red ditentukan menggunakan Response Surface Methodology (RSM) berdasarkan pengujian dengan Box Behnken Design (BBD). Variabel yang digunakan yaitu konsentrasi awal zat warna, pH dan waktu kontak. Persentase efisiensi degradasi zat warna procion red mencapai 96,05% di bawah kondisi optimum pada konsentrasi awal zat warna 60 mg/L, pH 3 dan waktu kontak 75 menit mengikuti model kuadratik.
