Respon Pertumbuhan Semai Suren (Toona Sureni) Terhadap Pemberian Kompos Kotoran Kambing Pada Media Tanam Bekas Tambang Emas

Mining activities affect the balance of the land surface ecosystem, reducing soil productivity and environmental quality. The negative impacts that arise can damage the forest which causes the chemical, biological and physical properties of the soil to be disturbed. For this reason, efforts are made to restore soil conditions to their original state through revegetation (greening) activities. Utilization of Toona sureni plants on less fertile and nutrient-poor soils requires the addition of organic matter to improve soil quality through fertilization, such as the application of goat manure compost. The purpose of this study was to determine the effect and best composition of a mixture of compost and ex-gold mine soil in the growth of Toona sureni seedlings. This study consisted of 4 (four) treatments and 5 (five) replications resulting in 20 experimental units. The treatment of compost fertilizer in this study can be seen as follows: D1 = no 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 observation parameters were the percentage of survival, height increase, diameter increase, seedling sturdiness, plant dry weight, root crown ratio and seedling quality index (IMB). The results showed that the application of goat manure compost had a significant effect on the growth of Toona sureni seedlings. Treatment composition D4 (75% compost fertilizer + 25% gold mine waste soil) showed the best growth with 100% survival rate, 21.27 cm height increment, 2.45 mm diameter increment, 4.83 seedling sturdiness, 10.57 g plant dry weight, 5.80 root crown ratio and 0.99 IMB.
