Abstract

Fibre-based composites continue to be investigated and developed as alternative materials to replace metals, primarily due to their advantageous properties of high strength and lower weight compared to metals. This study aims to fabricate fibre composites using ijuk fibres and coconut coir fibres as a matrix with epoxy resin. In this research, mixtures of ijuk fibres, coconut coir fibres, and epoxy resin were prepared in proportions of 20%:30%:50%, 25%:25%:50%, and 30%:20%:50%. The highest bending strength test results were obtained in specimen 3, which consisted of a mixture of 30% palm fibre, 20% coconut fibre, and 50% epoxy resin.  This specimen had a tensile strength value of 18.93 MPa and an impact value of 0.387 Joules/mm². This result can be attributed to the increasing proportion of ijuk fibres and the decreasing proportion of coconut coir fibres within the epoxy resin matrix, which influences the elastic strain of the fibre core (cellulose). The higher cellulose content of ijuk fibres enhances bending strength and impact resistance. This is supported by the impact (Charpy) test results, where specimen 3 (30%: 20%:50%) exhibited the highest bending and impact strength. Conversely, increasing the proportion of coconut coir fibres reduced the impact strength. The fracture morphology revealed that specimen 1 exhibited a brittle fracture, whereas specimens 2 and 3 exhibited a fibrous brittle fracture.

Abstract

Program pengabdian masyarakat ini dilaksanakan di Pondok Pesantren Markiz Darul Qur’an Wassunnah sebagai upaya mengatasi keterbatasan sumber dan distribusi air yang berdampak pada rendahnya produktivitas pertanian dan peternakan. Kegiatan ini bertujuan meningkatkan efisiensi sistem pengairan pertanian melalui penerapan teknologi submersible pump pada lahan kelompok tani mitra. Sebelum program diterapkan, petani menghadapi keterbatasan pasokan air irigasi akibat ketergantungan pada curah hujan serta penggunaan metode pengangkutan air manual yang memerlukan waktu dan tenaga besar. Kondisi tersebut menyebabkan keterlambatan masa tanam, ketidakteraturan irigasi, dan penurunan hasil produksi. Melalui program ini, dilakukan instalasi submersible pump yang disesuaikan dengan kebutuhan lahan, disertai pelatihan operasional dan perawatan bagi petani. Hasil implementasi menunjukkan peningkatan signifikan pada ketersediaan air, dengan debit yang lebih stabil dan distribusi yang lebih merata. Efisiensi waktu pengairan meningkat lebih dari 50%, serta kondisi pertumbuhan tanaman menunjukkan perbaikan nyata. Peningkatan kapasitas petani dalam mengoperasikan teknologi turut mendukung keberlanjutan program. Secara keseluruhan, teknologi submersible pump terbukti efektif sebagai solusi pengairan yang meningkatkan produktivitas dan efisiensi kerja petani.
