Abstract

Preparation of manganese oxide by sol-gel method and its application as a catalyst for methyl orange (MO) degradation was carried out using hydrogen peroxide as an oxidant.The characterization of manganese oxide was conducted using X-Ray Diffraction and Scanning Electron Microscope. The effect of initial concentration of MO was examined. Degradation efficiency was decrease with increasing the concentration of MO. The degradation kinetics ofMO followed the second-order reaction kinetics.

Abstract

Pengelolaan sampah organik rumah tangga merupakan tantangan lingkungan yang signifikan di Desa Bungaraya, yang berdampak negatif terhadap kebersihan lingkungan dan kesehatan masyarakat. Program pengabdian ini bertujuan untuk memberdayakan masyarakat dalam mengurangi limbah organik melalui pelatihan pembuatan sabun cair eco-enzyme. Metode yang digunakan meliputi penyuluhan, demonstrasi, dan praktik langsung, dengan partisipasi aktif sebanyak 30 warga. Hasil kegiatan menunjukkan peningkatan pengetahuan dan keterampilan peserta terkait pengelolaan sampah dan produksi eco-enzyme. Selain berkontribusi dalam mengurangi sampah organik, produk sabun cair yang dihasilkan bernilai ekonomi dan dapat dimanfaatkan secara pribadi maupun dijual untuk menambah pendapatan rumah tangga serta memberikan kontribusi terhadap keberlanjutan lingkungan sekaligus menguatkan potensi ekonomi berbasis komunitas.
