Abstract

Mining is one of the activities of management and utilization of natural resources as an effort to fulfill human needs and is the largest contributor to foreign exchange, mining business activities in forest areas used to support development have caused environmental damage and must be reclaimed immediately. This study aims to describe the status of tree growth in post-mining land and evaluate the causes of health problems in tree growth in post-mining land. The method used in this study uses two blocks of objects carried out at one location, namely in block 7. The parameters measured in identifying the status of this growth are plant diameter, plant height, percent plant growth, percent health of plants and soil samples. The types of plants observed in this study were sengon (Paraserianthes Falcateria), lamtoro (Leucaena Leucocephala). The results showed that based on two observation blocks, namely block a with lamtoro and block b with sengon plants, the percent growth and the best percent health were in block a where percent grew by 83% and percent health of the plant by 100%. On the other hand, in blocks of b percent, plant growth is only 37% and percent of plant health is 00.0%. Based on the lab results on soil sampling from each block, block B has a very low nutrient content compared to block a. The results of soil analysis on the observed blocks showed that there was a low nutrient value in nitrogen (N), potassium (K), and phosphorus (P).Keywords: post-mining land, nutrient deficiency, plant growth.

Abstract

Medicinal plants are medicinal plants that can relieve pain, increase endurance, prevent and cure diseases. The use of natural materials as traditional medicine in Indonesia has been carried out by our ancestors since centuries ago until now still exists, especially in the village of Malonas, Dampelas District, Donggala Regency, Central Sulawesi Province. The purpose of this study was to determine the diversity of medicinal plants in the Production Forest area of Malonas Village, Dampelas District, Donggala Regency. This research was carried out in the production forest of Malonas Village, Dampelas Subdistrict, Donggala Regency, which was held for 2 months, from July to August 2018. This study used a single plot method which was purposively placed based on the location of medicinal plants. The minimum sample plot area used is determined by the area species curve. The results of the research conducted show that the number of seedlings and understorey medicinal plants that can grow in this area is greater, because the growth rate of the lower plants has a high diversity and species richness index influenced by the topography of the slope-sloping research site and at least cover from canopy at the level of growth of poles and trees. It can be seen from the results of calculation of tree level diversity index (H ') (0.69), pole level (0.61), stake level (0.63), seedling level and understorey (1.33). So the diversity of medicinal plants according to growth rates is generally classified as low.Keywords: Malonas Village Production Forest, Medicinal Diversity

Abstract

Teak (Tectona grandis L.f) is a timber commodity that has a very high economic value. High teak needs are not in line with the ability to procure teak wood which is still low. Teak growth is often hampered by improper growing conditions, especially in former mining areas. Gold mining activities will also cause a decline in soil microbial population, damage to flora and fauna and the production of tailings from these mining activities. This condition needs treatment through fertilizer application. Urea is a nitrogen fertilizer that is needed by plants to stimulate overall growth, especially stems, branches and leaves. The success of a plant does not escape the use of superior, healthy and quality seeds. The research was conducted for three months, namely from June to August 2016 at Poboya, Mantikulore District, Palu City, Central Sulawesi Province. The material used in the implementation of this study was Semai Jati (Tectona grandis L.F) and urea fertilizer. This study used a completely randomized design consisting of 6 treatments and 3 replications, so that there were 18 experimental / observation units. Sidik Ragam analysis was conducted to determine the effect of the treatment that was tried on teak seedlings. Honest Real Test (BNJ) is conducted to see the effect or treatment. The results showed that the treatment of urea fertilizer had a significant effect on the parameters of height increase and the number of teak seedling leaves, while the increase in diameter had no significant effect. The treatment of P1 (2 g / seed) gave the best influence on all parameters added to the teak seedlings observed.Keywords: Urea Fertilizer, Teak Seedlings, KPH, Poboya Mining Mine.
