Abstract

Gold mining is a human activity with high environmental risk through its tailing, due to the heavy metals content. Lead (Pb) is one of dangerous heavy metals in the world, because its toxicity to organism and environment. Phytoremediation is a method to remove hazard pollutant from environment by using plant. Acacia mangium is fast growing and pioneer tree species which mostly grow on the secondary forest as well as marginal land. Usually, this species is used for revegetation on postmining land. Study on Pb effect to A. mangium is an important issue to support phytoremediation advancement as well as for forest restoration. This study aimed to analyze the effect of Pb with several levels toward the growth and adptability of A. mangium on the gold tailing. The results showed that Pb increment on tailing were significantly effect on the growth and adaptability of the plants. A. mangium showed a well performance even on 900 mg Pb/kg tailing with high tolerance index (TI > 100%). Moreover, this species had ability to accumulate Pb in the root higher than shoot tissue. A. mangium had a good potency as phitoremediant plant, also as revegetation plant on the marginal land, such as on the gold mining tailing. Key words: Acacia mangium, heavy metal, lead, phytoremediation, Pb

Abstract

Reclamation activities should be carried out after mining operation for restoring and improving the function of the land to be in better condition and productive (P.60/Menhut-II/2009). This research aims to analyze the status of the success of revegetation, based on growth ability and performance of A. mangium plants at PT Jorong Barutama Greston Block M1W; to recommend improvements for the land and plants; and to identify the cause of revegetation failure. The results of this research indicated that status of the revegetation success at Block M1W have not been categorized as successful category. The success rate were considered from the average growth percentage and health level of plants which were less than 60% (score 1, bad performance), namely 59.38% and 50.01% respectively. The improvement that could be done were soil amendment and the use of plants which are resistant to poor environment. The plants have to be resistant to acid soil and high content of heavy metal. The main causes of revegetation failure were site condition which were not conducive for A. mangium plant growth and lack of plant maintenance. This was the cause of bad plant growth performance. Besides that, Standard Operational Procedure (SOP) on revegetation activities need to be improved and plant maintenance should be enhanced, particularly those related with pest and disease control.Key words: A. mangium, evaluation, post coal mining, revegetation

Abstract

Nickel mining in Bombana District is one of the mining activities which generates a very large income for the area. However, mining carried out continuously will certainly cause the environment to be damaged, especially soils and vegetation when mining activities end. Good management of post-mining land is one of the obligations of the mining business unit. Management can include reclamation and replanting land so that exposed land can be reforested. Reforesting ex-mining land is not easy. These efforts need to be carried out with comprehensive treatment concerning the improvement of the vegetation composition as well as the physical, chemical, and biological aspects of the soil used so that the greening plants that are introduced can adapt well. The purpose of this study is to identify and compare the characteristics of vegetation and soil in lowland natural forests, plantations and post-nickel mining in Bombana District. In this study, observations were made at three different locations to look for differences in characteristics caused by the existence of nickel mining activities. From the results of the study showed that there was a decrease in the composition of vegetation due to changes from natural forest to plantations. In addition, the level of soil fertility is also declining due to land clearing for mining. Key words : nickel, mining, Bombana, soil, vegetation

Abstract

Forest and land fires are phenomena that often occur in Indonesia and have a negative impact on life. One of them is carbon dioxide gas emissions which influences global climate change. Therefore, information is needed regarding the estimation of carbon dioxide emissions in fire-prone areas, one of them is West Kalimantan, as a consideration in the activity to control forest and land fires. The method that is applied in this research is by estimating the area of the burned area then estimating carbon dioxide gas which refers to the loss of burning biomass. The results showed that the number of hotspots detected in Ketapang Regency sequentially in 2013, 2015, and 2017 amounted to 368, 2824 and 141 hotspots which were dominated by mixed dry-land agriculture, swamp shrub and shrub. Meanwhile, emissions of carbon dioxide gas produced in 2013, 2015, and 2017 in mineral soils amounted to 644 135.92 tons CO2, 3 455 169.72 tons CO2 and 293 967.87 tons CO2, while in peat-lands emissions emitted are 48 162.91 tons of CO2, 919 640.45 tons of CO2 and 10 835.71 tons of CO2.

Abstract

Forest protection is an effort to prevent and control the destruction of forests, forest areas, and forest products caused by human actions, livestock, fires, pests and diseases. The aims of this research are to identify the types of forest disturbance especially those caused by humans and physically, analyze the factors causing forest disturbance, and analyze efforts to control forest disturbance at KPH Kuningan. Forest disturbances that occurred in the KPH Kuningan during 2010-2014 included: timber theft, forest fires, forest encroachment, and natural disasters. The background of forest disturbance in the Kuningan KPH is mainly due to the socio-economic conditions of the community around the forest that are still low. Strategic actions taken to prevent forest disturbance at the KPH Kuningan are to take pre-emptive actions in the form of counseling and establish good relations between officers and the community through social communication and Community Based Forest Management (PHBM), preventive actions in the form of patrols and safeguards against forest potential, and repressive actions in the form of legal remedies against the perpetrators. Key words: cause of forest disturbance, type of forest disturbance, forest disturbance control
