Journal of Degraded and Mining Lands Management Vol 1, No 2 (2014)
Publisher : Brawijaya University

Phytoremediation has been widely used for wastewater treatment technology. Horsetail was investigated for its capacity to remediate lead and chromium in leachate. This plant seemed to be an effective choice for phytoremediation due to its survival in extreme to moderate conditions, the availability of annual or perennial varieties and a deep root system. Conducted in a greenhouse, this research used leachate from final disposal. The leachate was exposed to six treated plants with three multiplications using activated natural zeolite media for one month. The treatments were flow system i.e. batch and continue, and living plants weight that is 0, 153 and 306 g planted in 20 cm diameter and 30 cm deep pots. The leachate pH, temperature, lead, and chromium concentration were observed and also the surrounding temperature and humidity. Results showed that 82.2% of lead can be removed by 153 gram horsetail on batch system as well as 61.2% chromium removal by 153 gram horsetail on continue system. Horsetail seemed to have future to be applied in phytoremediation of artisanal and small scale mining waste.

This research was conducted to evaluate ecosystem function of post-sand mining land in northern side of Layapan, Cimalaka, Sumedang, West Java (S 6o 47’ 33.68” and E 107o 58’18.73”, 744 m above sea level). Microclimate and soil characteristics measurements were carried out to describe the physical and chemical characteristics of the land. Vegetation analysis was conducted with plotting method. Ecosystem Function Analysis, including Landscape Function Analysis (LFA) has been used to analyze the function of landscape. The results showed that average light intensity, air temperature and humidity were 15.2x103 ± 7.3x103 lux, 29.1±1.02oC and 69.7±7.5%. High light intensity made the air temperature rouse higher than normal, which is between 17.1oC to 22oC. As for the soil, soil organic content was 4-11%, porosity 4.65-24.43%, macronutrient content was low and C/N ratio was high. The results showed that LFA value for land stability was 33.24%, water infiltration 37.2%, nutrient cycle rate 15.28%. Those numbers showed that land condition was poor. From the LFA data, it was also known that vegetations had the highest contribution for all LFA parameters. From vegetation analysis, herbs species were 67 while bushes only 9, which at least 40 species were invasive alien species. Species with highest Important Value (IV) from herb was Cajanus scarabaeoides and from bush was Mimosa pigra. Both of them are members of Fabaceae. It was concluded that the soil of this post sand mining land was highly nutrient poor; critical and couldn’t perform the regulation, habitat and biomass production function of ecosystem.

A field experiment that was aimed to elucidate the effects of application of Arachis pintoi biomass and animal dung on quality of soil continuously used for cassava cropping was conducted at Jatikerto Village, Kromengan District of Malang Regency. Eight treatments tested were 100% NPK inorganic fertilizer, 100 kg N Arachis pintoi/ha, (3) 100 kg N chicken dung / ha, 100 kg N cow dung /ha, 100 kg N goat dung /ha, 100 kg N Arachis pintoi + chicken dung /ha, 100 kg N Arachis pintoi + cow dung /ha, and 100 kg N Arachis pintoi + goat dung /ha. Monitoring quality of top soil (0-20 cm) was carried out at planting time and 3 months after planting. Soil samples were collected and analyzed for chemical and physical properties. Yield of cassava was measured at 6 months after planting. Results of this study showed that application of organic fertilizer in forms of green manure (Arachis pintoi biomass), and animal dung significantly improved physical and chemical properties of soil. Application of 50% NPK combined with organic manures did not significantly gave different tuber yield with that of 100% NPK.

Phosphorus solubilizing bacteria (PSB) enhances P availability in soils through dissolving inorganic P pools. The characteristics of PSB and the potential of three Pb tolerant phosphate solubilizing rhizobacteria, i.e. Pseudomonassp, Bacillus sp., and Actinomycites sp. were evaluated. PSB were isolated from soil samples contaminated with 300 and 500 mg Pb/kg after incubation for 30 days. Phosphate solubilizing bacteria were screened on for phosphate solubilisation ability in Pikovskaya agar medium (PA). In addition, two of the three indentified PSB strains (Pseudomonas sp. and Bacillus sp.) were characterized for their ability to solubilize tricalcium phosphate in Pikoskaya broth (PB) and also were examined their growth during culture medium incubation. The isolates exhibited different phosphate solubilization index, ranging from 1.87 to 2.98. Pseudomonas sp. had the highest ability to solubilize tricalcium phosphate: 9.82 mg P/ L and 12.23 mg P/ Lin Pikoskaya broth following the addition of 4 mg Pb/L and 2 mg /Pb L, respectively.

Potential use of soil-born fungi isolated from treated soil in Indonesia to degrade glyphosate herbicide N Arfarita; T Imai; B Prasetya

Publisher : Brawijaya University

The glyphosate herbicide is the most common herbicides used in palm-oil plantations and other agricultural in Indonesial. In 2020, Indonesian government to plan the development of oil palm plantations has reached 20 million hectares of which now have reached 6 million hectares. It means that a huge chemicals particularly glyphosate has been poured into the ground and continues to pollute the soil. However, there is no report regarding biodegradation of glyphosate-contaminated soils using fungal strain especially in Indonesia. This study was to observe the usage of Round Up as selection agent for isolation of soil-born fungi capable to grow on glyphosate as a sole source of phosphorus. Five fungal strains were able to grow consistently in the presence of glyphosate as the sole phosphorus source and identified as Aspergillus sp. strain KRP1, Fusarium sp. strain KRP2, Verticillium sp. strain KRP3, Acremoniumsp. strain GRP1 and Scopulariopsis sp. strain GRP2. This indicates as their capability to utilize and degrade this herbicide. We also used standard medium as control and get seventeen fungal strains. The seventeen fungal strains were identified as species of Botrytis, Fusarium, Aspergillus, Penicillium, Verticillium, Trichoderma and Paecilomyces. These results show the reduction in the number of fungal strains on solid medium containing glyphosate. Of the five isolated fungal species, Verticillium sp. strain KRP3 and Scopulariopsis sp. strain GRP2 were selected for further study based on their highest ratio of growth diameter. This study indicates that treatment of soil with glyphosate degrading fungus would be useful in some areas where this herbicide is extensively used.

A glasshouse experiment was conducted to study the interactive effects of biochar amendment and arbuscular mycorrhizal fungi (AMF) inoculation on phosphorus uptake by maize (Zea mayze L.) grown on a calcareous soil of Kupang, East Nusa Tenggara. The biochar was made of cow dung. Twelve treatment combinations (three biochars levels of 0, 5 and 7.5 g/kg of soil, and four AMF inoculation levels of 0, 5, 10 and 15 spores / kg of soil) were arranged in a completely randomized block design with three replicates. Results of the study showed that at 8 weeks after transplanting, the biochar and mycorrhizal treatments increased the availability soil phosphorus and phosphorus uptake by maize. Application 4.5 and 7.5 g biochar/kg of soil combined with inoculation of 10-15 AMF spores / kg of soil provided to high value of phosphorus uptake by maize. Application of biochar alone, however, did not significantly improve maize growth and phosphorus uptake by maize.

Publisher : Brawijaya University

The effect of mixing of Tithonia diversifolia and Lantana camara prunings to improve synchronization between P released from the prunings with crop demand for P was studied in a laboratory and in a glasshouse. Tithonia diversifolia prunings (Td), Lantana camara prunings (Lc), and farmyard manure (Pk) were thoroughly mixed with the proportion (% of dry weight) of; 25Td +75 Lc ; 50Td +50 Lc ; 75Td +25 Lc ; 90Lc +10 Pk ; 45Td +45 +10 Lc Pk ; 100Td and 100Lc, and then mixed with 100 g of air-dried soil with a rate equivalent to 100 kg P / ha. Results of the study showed that the pruning mixtures decomposed and mineralized faster than that of Lantana camara pruning only, but slower than that of Tithonia diversifolia pruning only. The amount of P released from the pruning mixtures increased with increasing proportion of Tithonia diversifolia pruning in the mixtures. Increasing proportion of Tithonia diversifolia pruning in the mixture applied to the soil increased the amount of P taken up by maize.

Publisher : Brawijaya University

Based on agro-climate factors, most of surrounding area of coal mining sites in Indonesia is suitable for cocoa cultivation. However, most of cocoa farmers in the environs of coal mining sites have little access both to new technology of cocoa cultivation and to market of their cocoa products. Therefore, productivity of cocoa farms and the income of cocoa farmers are low, which may disturb social responsibility of the coal mining companies present in their surroundings. These are the consequences of poor interaction between the government, private sector and research sector. The aim of this study is to transfer and to implement good agricultural practices of cocoa in surrounding area of mining sites of Kaltim Prima Coal (KPC) and Berau Coal (BC), East Kalimantan, in order to increase farmer capacity and cocoa productivity. Indonesian Coffee and Cocoa Research Institute as the developing agent of cocoa technology has established collaboration with corporate social responsibility program of KPC (already 7 years) and BC (already 2 years) to improve productivity and farmer capacity of cocoa farms surroundings the two cocoa mining companies. This paper discusses the aspects of natural, economic and human resources; baseline study; technology transfers; marketing partnership; cocoa productivity; farmer income after technology implementing; study of cocoa growth on post-coal-mining. It is concluded that improvement of the cocoa productivity and farmer capacity surroundings the two mining sites associated with high adoption of technology by farmers, better access to availability of knowledge for good agricultural practices, extension officers, demonstration plots, cocoa price, and length of market chains, partnership, and competition with oil palm plantations.
