Efektivitas Bioinsektisida Daun Eceng Gondok (Eichhornia crassipes) Terhadap Kematian Ulat Grayak (Spodoptera litura) Dan Biomassa Bayam Merah (Alternanthera amoena Voss)

The application of vegetable insecticides derived from water hyacinth leaf extracts was used to determine the mortality rate in armyworms on red spinach plants. The analysis observed from the number of leaves and production of red spinach plants, natural insectide treatment used concentrations of P0 (0%), P1 (5%), P2 (10%) and P3 (15%). The research analysis used a completely randomized design (CRD) with 4 treatments and 6 replications, the data obtained were analyzed using the ANNOVA test and the Duncan test. The results showed that presenting a plant-based insecticide on water hyacinth leaf extract had a significant effect (P <0.05) on the number of armyworm mortality, red spinach plant growth (number of leaves) and production of red spinach. The results of the Duncan test analysis showed that the P3 treatment (15%) was significantly different from other analyzes.   Keywords: bioinsecticide, water hyacinth leaf extract, armyworm caterpillar, growth, yields, mustard plants.Pemberian insektisida nabati berasal dari ekstrak daun enceng gondok untuk melihat tingkat kematian pada ulat grayak pada tanaman bayam merah. Analisis yang diamati dari jumlah daun dan produksi tanaman bayam merah, Perlakuan insektida alami menggunakan konsentrasi P0 (0%), P1 (5%), P2 (10%) dan P3 (15%). Analisis penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 6 kali ulangan, data yang diperoleh dianalisis menggunakan uji ANNOVA dan uji Duncan. Hasil penelitian menunjukkan bahwa mempersembahkan insektisida nabati pada ektrak daun eceng gondok memberikan pengaruh nyata (P <0,05) pada jumlah kematian ulat grayak, pertumbuhan tanaman bayam merah (jumlah daun) dan hasil produksi tanaman bayam merah. Hasil analisis uji Duncan bahwa pada perlakuan P3 (15%) berbeda nyata dengan analisis lainnya. Kata kunci: bioinsektisida, eceng gondok, ulat grayak, pertumbuhan, produksi, tanaman sawi
