Pengaruh Pemberian Pupuk Kompos Terhadap Pertumbuhan Semai Sengon (Paraserianthes Falcataria) Pada Media Tanam Bekas Tambang Emas

ABSTRACT
Gold mining activities produce waste in the form of rock dumps and tailings. The waste from mining has a negative impact on the environment if not handled properly. Tailings contain metal mercury and elemental cyanide that can poison plants, animals and humans. For this reason, efforts are made to restore soil conditions to their original state, especially by revegetation using Paraserianthes falcataria. P. falcataria can grow in various types of soil. The growth of P. falcataria on the ex gold mine soil requires organic materials that can provide nutrients for plants, such as compost. The purpose of this study was to determine the effect and best composition of a mixture of compost and ex gold mine to spur the growth of P. falcataria seedlings. This study consisted of 4 treatments and 5 replications resulting in 20 experimental units. Dosage of compost fertilizer in this study are: D1= without compost (control), D2= 25% compost + 75% ex gold mine soil, D3= 50% compost + 50% ex gold mine soil, D4= 75% compost + 25% ex gold mine soil. The parameters observed were the percentage of life, height increase, diameter increase, plant dry weight and root crown ratio. The results showed that the application of compost fertilizer affects the growth of sengon seedlings. Treatment composition D4 (75% compost fertilizer + 25% ex gold mine soil) showed the best growth with 100% live percent, 26.75 cm height gain, 2.66 mm diameter gain, 6.90 g plant dry weight and 5.99 top root ratio.
Keywords: compost, ex gold mine, growth, P. falcataria
