Abstract

Permasalahan utama yang dihadapi oleh pelaku UMKM di Desa Karangkuten, Kecamatan Gondang, Kabupaten Mojokerto adalah kurangnya pemahaman dalam menerapkan strategi pemasaran digital yang efektif. Tujuan kegiatan ini adalah memberikan sosialisasi dan pelatihan kepada pelaku UMKM terkait pemanfaatan media sosial dan teknologi kecerdasan buatan (AI) dalam menunjang pemasaran produk. Metode yang digunakan adalah penyuluhan langsung disertai dengan penyebaran kuisioner untuk mengetahui kondisi aktual dan kebutuhan peserta. Hasil kegiatan menunjukkan bahwa mayoritas pelaku usaha masih menggunakan metode pemasaran konvensional dan belum mengoptimalkan platform digital, meskipun sebagian telah memanfaatkan WhatsApp dan Facebook. Sosialisasi ini berhasil meningkatkan kesadaran peserta tentang pentingnya digital marketing serta mendorong ketertarikan terhadap pelatihan lebih lanjut, khususnya dalam hal fotografi produk dan penggunaan AI seperti ChatGPT. Kegiatan ini menjadi langkah awal dalam mendorong transformasi digital bagi UMKM agar mampu bersaing di era industri 4.0.

Abstract

This study presents a sustainable approach for synthesizing calcium peroxide (CaO₂) nanoparticles from biogenic eggshell waste as a potential adsorbent for wastewater treatment. Increasing water pollution caused by industrial and domestic activities has driven the demand for low-cost and environmentally friendly adsorbents. In this study, eggshells from various poultry sources were calcined at 900°C to produce CaO, followed by hydration and chemical precipitation using H₂O₂ to synthesize CaO₂. The resulting materials were dried at different temperatures (60–100°C) to evaluate the effect of thermal treatment on structural properties and adsorption performance. X-ray diffraction (XRD) analysis confirmed the formation of CaO₂ with nanoscale crystallite sizes ranging from 15.3 to 28.85 nm. Brunauer–Emmett–Teller (BET) analysis showed specific surface areas between 10.18 and 19.67 m²/g. Adsorption experiments using acetic acid revealed that performance was significantly influenced by precursor type and drying temperature. The highest adsorption capacity (347.54 mg/g) and removal efficiency (34.75%) were achieved using CaO₂ derived from free-range chicken eggshells at 80°C. This enhanced performance is attributed to the natural biogenic structure, mineral composition, and pore distribution. Overall, eggshell waste is a promising, sustainable, and cost-effective precursor for producing high-performance CaO₂ nanoparticles for wastewater treatment
