Abstract

Tailing is one form of waste produced in large quantities in the gold mining activities are nutrient poor. Therefore it is necessary for land revegetation in these tailings. Revegetation activities must be conducted on former mining land, but often encounter obstacles that revegetation efforts are quite heavy. The success of revegetation on land that is dominated by tailings require plants that are able to adapt as mahagony seedling (Swietenia macrophylla), which has the potential if planted in dry soil as the soil tailings. This study used a complete randomized design. The results showed 30 grams of compost fertilizer effect is very real influence with the percentage growth of 40.70% against the control with an average growth of 6.81 cm.

Abstract

Growth of Jabon (Anthocephalus cadamba  Roxb. Miq.) on PT ANTAM Unit Bisnis Pongkor’s Tailing with Top Soil and Compost AdditionGold  tailing has some characteristics such as low of organic material and microorganism activity, deficient in nutrition andlow of CEC (cation exchange capacity). This constraint to revegetation, therefor soil amandment needed before revegetation program. Top soil and compost addition, which can improve soil condition and nutrition, also as microbe source.It is necessary to select tree species for revegetation post mining activity. Pioneer species that chosen have to well adaptive, fast growing, known silviculture techniques, available in plant resource, microbial symbiosis and catalytic. One of the potential species is jabon (Anthocephalus cadamba Roxb. Miq.). The result of this research is growth respon of jabon on  tailing with  top soil and compost addition can improve growth of tall, stem diameter  and root biomass. The best dose combination are 20 grams compost combine with 250 grams top soil.

Abstract

Comparison of Soil’s Chemical and Biological Characteristics Caused Land Openness of Pine Reforested Forest in Pollung Sub-district of Humbang Hasundutan District, North Sumatera.Forest clearing activity has been caused land openness in some forest areas such as reforested forest. Land openness could cause the decreasing of fertility value of forest soil. The objective of this research was to comparing of soil’s chemical and biological characteristics in open area with pine forest in pine reforested forest in Pollung sub-district of Humbang Hasundutan district, North Sumatera. This research was using secondary data of soil’s chemical and biological characteristics analysis results from Team of Living Environmental Ministry 2010. Descriptively, this research has shown that land openness has caused lower comparison of all average value of soil’s chemical and biological parameters. Highest percentage of comparison difference in open area was total of C-organic content that amounted 59.90% and total of soil fungi that amounted 94.18 % lower than pine forests. Degradation of soil’s chemical and biological values was caused by the decreasing of total organic content of soil and nutrient washing by rain water. Considering to negative impact that will be caused thus needed an effort of soil resiliency through land rehabilitation by whitewashing of acid soil and re-vegetation

Abstract

Land  cover  changes will affect the ecological condition of  the watershed.  Currently, the  conversion of  natural forests into agricultural land has been one of  the main  causes of  deforestation  in  Indonesia. The  changes  could  give impact to  erosion,  increased  run off  and  sedimentation,  loss of  biodiversity,  change of micro  climate,  the release of carbon and Green House Gas (GHG) into the air, etc. This problem has been going on in Watershed Ciliwung.  Forest area, as sources of carbon deposits and carbon absorbents, has limited area along with increasing extents of build up areas. Therefore, it’s estimated the ecological changes will be extended, then will affect the amount of carbon  stocks in Watershed Ciliwung. The objectives of research are  to determine  land cover changes during  the  last twenty years,  to analyze actual carbon stocks in watershed Ciliwung, and to analyze the effect of land cover changes in over twenty years of greenhouse gases, especially CO2. This research used three samples plot on each of the existing land cover. Biomass approach was used in order to estimate carbon stock. Changes in carbon stocks were calculated by using interpolation based on  the actual  carbon  stocks  in 2011. The  research  results  showed  that build up areas was  increased  153,36% during twenty years. The highest potencial carbon stocks was  found in pines forests, which is 144,99 tons/ha. Over the last twenty years, carbon stocks in watershed Ciliwung is declined 42.329,75 tons carbon or 155.350,182 tons CO2e.

Abstract

Mining activity is an exploitation of natural resources, such as land clearing, extraction, digging and landfilling. One of mining activities that often done by people is sand mining. Some problems occur by sand mining, i.e. landslide, sedimentation, flood, the loss of soil organic matter, the loss of soil horizon, soil structure changes, air pollution in the form of dust particle and destruction of accessibility. Revegetation must be conducted on ex mined land, but it has some constraints, such as domination of sand texture, low CEC and low soil nutrient. Application of charcoal and NPK fertilizer are expected to overcome those problems. Krey payung has good adaptability in various soil types, producing a lot of litters for soil repairment, has a good crown to cover the soil and has attractive performance. The result showed that combination of charcoal without NPK fertilizer gave the best growth for krey payung seedling. The largest single charcoal application, i.e. 10 % in soil planting medium of ex sand mine gave the best growth for Krey payung seedling. Medium without NPK fertilizer gave the best response for krey payung seedling growth. The addition of NPK on soil medium of ex sand mining did not give good response for the growth of krey paying seedling.Key words: charcoal, krey payung, NPK fertilizer, sand mine

Abstract

Mining is one potential natural resources that can be used as a source of foreign exchange to national development. Activities in mining inflict negative impact on the environment in form of the damaged environment, habitat animals and loss of the kinds of flora/fauna endemic. To prevent and reduce the destructive power worse, we need to sought various effort control that lead to activity land rehabilitation one is modifying environment growing crops. One of them is giving coconut shells and bokashi on jabon to increase plant growth and productivity on critical land after mine for a relatively cheap.This research used data measurement of primary growth of jabon in the press cropping former gold mine (tailing). The method is applicable in the measurement of on high growth, diameter, the total weight of dry and NPA jabon on tailing with treatment granting coconut shells charcoaland bokashi in various doses for three months. Diverse analysis with the (Pr>f)<α (significant value<0.05)or influence the provision of charcoal and bokashi influential real on the growth of high In diameter, the total weight of dry and NPA of jabon on tailing, then test the continued to compare the middle value treatment. Further test used Duncan test.Based on the results, it can be said the addition of charcoal and bokashi were able to repair the structure and texture of the medium, so it can improve the tailings deposits of nutrient elements for plants. Treatment A4B3 (granting of charcoal with a dose of 10% and bokashi with a dose of 60 g) delivers the most flattering to increased growth of jabon on the gold mine tailings medium.Key words: Anthocephalus cadamba, bokashi, charcoal, growth, tailing

Abstract

Growth of Shorea stenopthera Burck. F. seed can naturally be associated with fungi Scleroderma columnare. A fall composting litter can accumulate on the floor of forest naturally, litter piles thickness affect the presence of fungi Scleroderma columnare that situated in the field around the trees rooting of Shorea stenopthera Burck. F. This research aims to examined the role of Scleroderma columnare fungi inoculation and the addition of litter against the growth of seedlings of Shorea stenopthera Burck. F. The treatments are designed using two factorials of completely randomized design for compost and fungi Scleroderma columnare. Compost factor consist of three levels, without compost, pure compost, and chopped compost. Fungi factor consist of two levels, with addition and without addition of Scleroderma columnare. The treatments repetition is 30 times, and observation data is analyzed by Duncan test (with 95% of confidence level), and test of variance for studying the interaction among diverse treatments. The results of the analysis gives significant difference between sample with treatment and sample without treatment (A0B0). Treatment A1B0 (chopped compost; without scleroderma) has the best response to the height of tree, trunk diameter, weight of wet leaf, and weight of stalks. Treatment A2B1 (pure compost; Scleroderma) showed the significant influence to the sum of wet trunks and percentage of colony. Treatment A0B1 (without compost; Scleroderma columnare) showed the significant difference on weight total of root against any other treatments.Key words : fungi Scleroderma columnare, litter, Shorea stenopthera Burck.
