Produktivitas Cacing Tanah (Lumbricus rubellus) pada Media Kotoran Sapi dan Janggel Jagung Fermentasi dengan Taraf Berbeda

Abstract

Cacing tanah berperan penting dalam penguraian bahan organik dan peningkatan kesuburan tanah. Budidaya cacing tanah memerlukan media yang sesuai dengan kebutuhan nutrisi dan kondisi lingkungan yang mendukung. Penelitian ini bertujuan menganalisis produktivitas cacing tanah (Lumbricus rubellus) pada media campuran kotoran sapi dan janggel jagung fermentasi dengan taraf berbeda. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 3 ulangan, yaitu J0 (100% kotoran sapi sebagai kontrol), J1 (95% kotoran sapi + 5% janggel jagung), J2 (90% kotoran sapi + 10% janggel jagung), J3 (85% kotoran sapi + 15% janggel jagung), J4 (80% kotoran sapi + 20% janggel jagung), dan J5 (75% kotoran sapi + 25% janggel jagung), serta uji lanjut Tukey. Hasil penelitian menunjukkan bahwa penggunaan kotoran sapi 85% dengan penambahan janggel jagung 15% (J3) memberikan hasil terbaik dengan pertambahan bobot badan rata-rata 4,57 g, jumlah kokon rata-rata 112 butir, jumlah populasi rata-rata 46 ekor, dan susut media rata-rata 133,99 g. Penggunaan janggel jagung melebihi 15% dapat menurunkan produktivitas cacing tanah.

Earthworms play an important role in decomposing organic matter and improving soil fertility. Earthworm cultivation requires appropriate media to support nutritional needs and environmental conditions. This study aimed to analyze the productivity of earthworms (Lumbricus rubellus) in a mixture of cow manure and corncob at different levels. The experiment used a completely randomized design (CRD) with 6 treatments and 3 replications, namely P0 (100% cow manure as control), P1 (95% cow manure + 5% corncob), P2 (90% cow manure + 10% corncob), P3 (85% cow manure + 15% corncob), P4 (80% cow manure + 20% corncob), and P5 (75% cow manure + 25% corncob), followed by Tukey's post hoc test. The results showed that the use of 85% cow manure with 15% corncob (P3) yielded the best performance, with an average body weight gain of 4.57 g, average cocoon number of 112, average population of 46 individuals, and average media shrinkage of 133.99 g. The addition of corncob exceeding 15% decreased earthworm productivity.
