Abstract

Salah satu limbah rumah tangga yang sering dijumpai adalah kulit telur atau cangkang telur. Cangkang telur mengandung banyak kalsium yakni sekitar 97% kalsium karbonat yang sangat dibutuhkan oleh tanaman. Kegiatan Pengabdian Kepada Masyarakat ini berupa sosialisasi yang di hadiri oleh Masyarakat Kampung Yoka Distrik Heram. Pada sosialisi tersebut dijelaskan cara mudah Pemanfaatan Limbah Cangkang Telur menjadi pupuk organik cair. Cara mudah yang dimaksud adalah dengan merebus Cangkang Telur. Membiarkan kulit telur mendidih dalam air panas untuk sementara waktu merupakan salah satu cara yang baik untuk menyedot kalsium ke dalam air. Selanjutnya air bekas rebus didinginkan. Setelah dingin, siram pada permukaan media tanam secara rutin sesuai jadwal penyiraman tanaman di rumah. Air rebusan cangkang telur dapat menetralkan pH tanah antara 6,0-6,5. pH tanah yang netral cenderung menjadikan tanah subur karena nutrisi yang terkandung dalam tanah mudah tersedia bagi tanaman. Pelaksanaan pengabdian kepada masyarakat ini menggunakan metode ceramah. Kegiatan sosialisasi ini dapat meningkatkan pengetahuan dan kepedulian masyarakat dalam mengoptimalkan pengelolaan limbah rumah tangga khususnya limbah cangkang telur.

Abstract

The present study highlights the effective utilization of waste fibers in structural composites for drone frame applications, offering a sustainable pathway for developing high-performance materials while simultaneously addressing the issue of textile waste pollution. This study investigates the effect of ramie and cotton fiber waste fabric stacking sequences on the physical and mechanical properties of composites for quadcopter drone frames. Waste fabric was selected as an eco-friendly material to address textile pollution. The composites were fabricated using the hand lay-up technique with a 3:1 epoxy resin to hardener ratio, incorporating five layers of fabric in different configurations. The physical and mechanical properties, including density, water absorption, material hardness, flexural strength, and macro photography, were tested. The results showed that the composite made from fully cotton fabric (K-K-K-K-K) had the best density (1.182 g/cm³), lowest water absorption (2.22%), highest hardness (85.6 HD), and flexural strength of 179.1 MPa. These findings indicate that cotton fabric waste is a promising, sustainable material for composite reinforcement in quadcopter drone frame applications.
