Suatu penelitian bertujuan untuk mengetahui pengaruh pemberian pupuk cair daun kelor (Moringa oleifera) terhadap kandungan nutrisi rumput gajah mini (Pennisetum purpureum cv. Mott) pada tanah bekas tambang mangan. Penelitian berlangsung selama 4 bulan. Rancangan penelitian yang digunakan adalah Rancangan Acak Lengkap dengan 4 perlakuan dan 4 ulangan yaitu K0: kontrol, K1: 100 ml pupuk cair, K2: 200 ml pupuk, K3: 300 ml pupuk cair. Variabel yang diukur adalah kandungan protein kasar, serat kasar, lemak kasar serta mineral kalsium. Data dianalisis dengan menggunakan analisis ragam. Hasil analisis ragam menunjukkan bahwa perlakuan berpengaruh nyata (P<0,05) terhadap kandungan protein kasar, kandungan lemak kasar, dan mineral kalsium tetapi berpengaruh tidak nyata (P>0,05) terhadap serat kasar. Uji lanjut Duncan menunjukkan bahwa antar perlakuan K0: K3, K1: K2, dan K1:K3 berbeda sangat nyata (P<0,01) pada parameter protein kasar dan mineral kalsium (Ca). Selanjutnya K0:K1, K2; K1: K2, K3; K2:K3; K0;K1, K2, K3 berbeda nyata (P<0,05) pada protein kasar, lemak kasar dan mineral kalsium (Ca). Sedangkan K1: K2: K3 berbeda tidak nyata (P>0,05) pada kandungan lemak kasar. Disimpulkan bahwa semakin tinggi level pupuk cair daun kelor (Moringa oleifera) maka kandungan nutrisi rumput gajah mini (Pennisetum purpureum cv. Mott) semakin tinggi. Kandungan nutrisi rumput gajah mini tertinggi dicapai pada level 300 ml dengan rataan kandungan protein kasar (10,15%), serat kasar. (42,93%), lemak kasar (1,15%) dan mineral kalsium (0,61%).

A study aims to determine the effect of applying Moringa oleifera (Moringa oleifera) liquid fertilizer on the nutritional content of mini elephant grass (Pennisetum purpureum cv. Mott) on ex-manganese mining soil. The study lasted for 4 months. The research design used was a completely randomized design with 4 treatments and 4 replications, namely K0: no treatment (control), K1: 100 ml of liquid fertilizer, K2: 200 ml of fertilizer, K3: 300 ml of liquid fertilizer. The variables measured is crude protein, crude fiber, crude fat and calcium minerals. The data obtained were analyzed using analysis of variance. The results of the study showed that the treatment had a significant effect (P<0.05) on the nutritional content of crude protein, crude fat and calcium minerals but had no significant effect (P>0.05) on crude fiber content. Duncan's Multiple Range Test showed that there is a significant difference (P<0.01) between the treatments of K0:K3 and K1: K2; K1:K3 on crude protein content and calcium (Ca) content. Furthermore, between K0:K1, K2; K1: K2, K3; K2;K3; K0;K1, K2, K3 were significantly different (P<0.05) in crude protein, crude fat and calcium (Ca) content. While K1: K2: K3 was not significantly different (P>0.05) on crude fat content. It was concluded that the higher the level of liquid fertilizer of Moringa leaves (Moringa oleifera), the higher the nutrient content of mini elephant grass (Pennisetum purpureum cv. Mott). The highest nutritional content of mini elephant grass was achieved at the level of 300 ml with an average crude protein content (10.15%), crude fiber. (42.93%), crude fat (1.15%) and calcium minerals (0.61%).
