Abstract

Mining activities in the forest areas are done through the land use of forest areas. The activities of mining must always be followed by reclamation and revegetation to restore the condition of damaged forest area as a result of mining efforts and forest areas can serve again in line with aimed. Revegetation is an effort to repair and restore the damaged vegetation by planting and maintenance activities on the grounds of forest areas former use. Evaluation needs to be done to find out the status of successful revegetation has been done by mining company. Purposes of this research are to assess the successful status of revegetation on post-mining land based on survival rate and plants performance of Acacia mangium on Block Q3 East Elevation 60 Lati Site of PT Berau Coal East Kalimantan. Observation also held to find out the causes of ineffective growth by result of soil analysis on post-mining land, and also to give recommendations of revegetation improvements.The result showed that the success of revegetation status on Block Q3 East Elevation 60 Lati Site is not successful based on survival rate and performance of planted plants. It is caused by the average values of growth and health plant percentage which lower than 80%. The average value of growth percentage is 79,31% and health plant percentage is 71,62%. The main factor of this condition is failure characteristics of soil revegetation which unsupport properly for the growth of plants. The level of soil acidity which appertain very acid soil can cause some important problems and it can be harmful to plants. Soil amendment and replanting vegetation should be done to improve revegetation on Block Q3 East Elevation 60 Lati Site PT Berau Coal East Kalimantan.Key words: Acacia mangium, evaluation, mining, revegetation

Abstract

The existence of dipterocarp species is very important especially in lowland tropical rain forest. Dipterocarp species has high economical and ecological values. Borneo is one of the region dipterocarp species. Logging has resulted in the decrease of dipterocarp species, moreover, mining industry has worsen this condition. According to IUCN (International Union for Conservation of Nature), that these kinds of plants have been categorized endangered. PT Kiadin in collaboration with Research Center of Dipterocarp Samarinda performed planting trials of various dipterocarp. The experiment was carried out in 2009 in the area of pre-conditioned post-mining area. The planting was done in five locations that had previously been planted with pioneer tree species in which each location had different types of shading. In order to know which dipterocarp species that is the most superior and in which locations these species existed, the growth of several types of dipterocarp in post-mining landscapes of PT. Kitadin was evaluated. This study aimed to identify which types of dipterocarp species that grew the best in various locations of revegetation of PT. Kitadin. Based on the research done, there was a tendency that five dipterocarp species grow well in the shade of waru. However, precentage of these five dipterocarp species life was mostly under the shade of trembesi. Parashorea smythiesii species had greater average height, diameter, and survival rates than those of other species. Thus, this species is a potential species that could be used too planting in the ex mine siter of PT. Kitadin.Key words: dipterocarp, growth evaluation, revegetation

Abstract

Soil characteristic on ex-mined land of coal generally has high acidity, solid texture, and has fitotoxic compound that causes plant dwarfishness. This research observed correlation between soil characteristic with plant diversity on revegetation area of ex-mined land of PT. Arutmin Indonesia Site Batu Licin, South Kalimantan. This research was done with measure height and diameter of plant Acacia mangium and Falcataria moluccana that planted 1 year and six months ago from 28 plots and also analysis of chemical and physical soil features from each plot. The result of this research found a dwarfishness on half revegetation plants in this research location, and as a factor that has real correlation with plant diversity.Keywords: Acacia mangium, Falcataria moluccana, ex-mined land, revegetation

Abstract

Aluminium (Al) phosphotoxicity is the most common constraint in acidic soil. Information on potential Al phytotoxicity is required in revegetation planning, monitoring of this information is generally done through laboratory analysis procedure in the laboratory that requires high cost and time. The purposes of this study were to test the method of quick detection of Al phytotoxicity with sorghum bioassay. Soil samples taken from post-gold mining land in Bolaang Mongondow Regency of North Sulawesi Province were analyzed for soil physical and chemical properties then planted with numbu varieties of sorghum with complete randomized design, sorghum growth performance response and its correlation with soluble Al and pH were analyzed and then the symptoms occured from Al-toxicity on sorghum were observed. Sorgum responds to Al-toxicity by showing symptoms of shortening and thickening of the roots and stunted growth performance. Sorghum growth performance has significant negative correlation with soluble Al concentration on soil, and soil acidity showed a stronger correlation. Al-phytotoxicity symptom in sorghum at pH below 3.7 begins to be clearly visible and easily observed, this distinct appearance difference makes sorghum potential to be used as bioindicator to detect Al- phytotoxicity on the soil.Keywords: Aluminium phytotoxicity, sorghum, post-mining revegetation

Abstract

Nursery activities were one important step in producing quality seedling. This study used a very low quality Gmelina seed with germination value of 9.8%. This value affected the ability of plants in responding to treatment. Input technology of growing media treatment and biostimulan needed to improve the quality of seedling. Sample of media planting collected from IPB permanent nursery. Applications biostimulan was using to help increased amount of plant roots. This study used a completely randomized factorial design with 7 replications. Observations for 8 weeks after planting (MST) found the media's treatment plant and biostimulan has significant effect on the parameters of diameter, height and total dry weight compared to control. Compost was the best medium in this study who had the highest NPK value compared to other media. Biostimulan concentration of 4% was proved improving the quality of Gmelina seedling in all media by increased the compactness of the roots of seedlings. The percentage increased in root dry weight (BKA), the largest found in the media mix of compost and mud. The best treatment in improving the quality of seeds Gmelina found in compost media and biostimulan 4% on all parameters of growth.Keywords: biostimulant, root compaction, seedling quality
