Abstract

Small-scale gold mining activities in Sekotong District of West Lombok Regency started in 2009. Gold is recovered through a two-stage process of amalgamation and cyanidation. Tailing is discharged to land with no concern for contaminants. Phytoremediation could cost-effectively replace traditional mercury remediation strategies. The objective of this study was to elucidate the potential of Cyperus kyllingia Endl for phytoremediation of soil contaminated with mercury of gold amalgamation and cyanidation tailings in conjunction with ammonium thiosulphate to phytoextract mercury. The study was conducted at the Laboratory of Soil Brawijaya University and in a shade house located in the area of ​​Dermo, Sengkaling. Samples of tailings-uncontaminated soil were mixed with samples of tailings with the proportion of 30%: 70% (w/w). At harvest shoots and roots were analyzed for mercury concentration in treatments, Tailing (tailings cyanidation and amalgamation), ligand ( 0, 4, and 8 g/kg ). The results showed that Cyperus kyllingia was a potential local species for phytoremediation of mercury contaminated soils as this plant was able to take up mercury of 122,53 mg/kg (shoot) and 77,9 mg/kg (shoot). Based on TF (translocation factor) value that was < 1, it is a potential species for phytostabilization. Addition on 8 g ammonium thiosulphate / kg planting media enhanced mercury taken up by plant as much as 71,18%. Key words: mercury , phytoremediation, ligand

Abstract

Landuse change are suspected to be one responsible to soil fertility decline on Slamparejo, Jabung, Malang. Efforts done by local farmers to deal with these problems are plantation of P. falcataria trough a reforestation program around 2003-2004. The benefits of the program are still need to be assessed so that this research was done (1) to compare the soil quality between P. falcataria-planted field and no P.falcataria field by the parameters of soil organic matter content and available N, (2) to study the relationship between organic matter input and soil organic matter content and available N, and (3) to identify factors affecting N availability post-P. falcataria plantation.This research used randomized block design with 5 treatments (annual crop field, 3 and 6 years P. falcaria plantation field, agroforestry field with P. falcataria + coffee + talas plantation, and ex-P. falcataria-planted field. Soil were sampled compositely by 3 replication from 0-20 cm depth. Litter were sampled from a 0.5m2 sub-plot of each treatment.Results showed that P. falcataria plantations enhance soil fertility indicated by increased soil organic matter input to 10.6 times (monoculture) and 17.6 times (agroforestry) control, increased soil organic matter content by 1.5 times (monoculture) and 2.3 times (agroforestry) control, increased total N of 1.6 times (monoculture) and 2.4 times (agroforestry) control, increased ammonium by 1.7 times (monoculture) and 3.2 times (agroforestry) control, and increased nitrate by 2.4 times (monoculture) and 3.9 times (agroforestry) control. The increased soil N content of P. falcataria-planted field were caused by higher soil organic inputs compared to those with no P. falcataria plantation. Nitrogen availability affected by soil texture but have no relationship with soil pH. However, agroforestry fields showed higher pH, organic C, total N, and available N than monoculture P. falcataria fields. Measured soil chemical properties showed no significant change by the increase of P. falcataria age, moreover, they declined down towards control on ex-P. falcataria plantation. This indicates that reforestation would only give a temporary soil quality enhancement.Key words: Regreening, Paraserianthes, Agroforestry, Soil organic matter, nitrogen total

Abstract

In 1984, The Indonesian Government and The Netherlands established a project to characterized land and soil conditions of Kali Konto Watershed that highly human populated, due the planning procedure for forest land management model report. Few years after the project, several lands on the area were cultivated intensively due the commercial purposes. The research objectives were: 1) to observe and identify the physical land conditions on Mount Anjasmoro toposequence; 2) to study the soil morphological changes, especially during the land use changes, and 3) define the soils development within the last 20 years. A field research was established in September 2005, in the same location of 1984 research, which depended on landform variations, 5 pedons were taken, known as: KK 28 (Volcanic hill, upper slope), KK 27 (Volcanic colluvial valley, middle slope), KK 39 (Inter volcanic plain, lower slope), KK 40 (Intervolcanic plain, lower slope) and KK 41 (Inter volcanic plain), have been analyzed accurately included soil description and soil sampling. Soil profile descriptions and laboratory analysis showed that every pedons on the Anjasmoro toposequence were changed. Soil morphology changed during the land uses conversion and intensive land cultivations. Land use on KK 28 has changed from natural forest to agricultural dry lands for about 15 years, and the soil classification changed from Typic Hapludands to Andic Dystrudepts. KK 27 has the unchanged land use, which is as an agroforestry land, but has the soil classification changing, Andic Hapludolls to Typic Hapludolls. KK 39 has the land use changing, which only in addition of grass under growth of the main vegetations. Land use changing in KK 39 has the unchanged soil classification, which is Fluventic Hapludolls. KK 40 not only has the unchanged land use, but also soil classification, which is mix garden land for the land use, and the soil classification is Typic Argiudolls. KK 41 has the unchanged land use, which as rice fields, but has the soil classification changing, which is Typic Hapludalfs to Fragic Oxyaquic Hapludalfs

Abstract

Maintaining litter thickness on agricultural land is one of key factor for maintaining diversity of nematode. Litter on soil surface is energy source of decomposer which will be consumed by bacterivore nematode. Higher litter input gives benefit to crop through maintaining diversity of non parasite nematode, improving soil porosity and soil moisture which important to control plant parasite nematode and achieve a sustainable crop production. The research was conducted to study diversity and abundance of nematodes in various landuse system and effect of different soil temperature and water content of various landuse system to nematode`s diversity and it`s abundance. Soil sampling on nine landuse system (degraded forest, bamboo forest, coffee multistrate, Gliricidia shade coffee, mahoghany plantation, pine plantation, Aghatis plantation, grassland and annual crop). Nematodes were extracted by sieving-centrifugation with sugar method. The soil nematodes were grouped into order and generic level including plant parasitic and non-paracitic. The result show that the diversity (number of taksa) and abundance of soil nematode in Konto watershed were high with a total of 44 taksa nematode genera and a total number ranged 334-910 individuals/300 cc of soil. The nematode`s diversity was decreased from 44 genera in degraded forest to 24 genera in Gliricidia shade coffee. The diversity and abundance of nematodes was not linked to variation of water content, but were correlated to plant vegetation and clay content. Diversity of Free-living nematodes was closely correlated with plant diversity (R2 = 0,69) and litter biomass (R2 = 0,32). While plant parasitic nematodes was closely correlated and significant with clay content (R2 = 0,62).Key words: nematodes, diversity, landuse system

Abstract

Landsliding duration is the time span between saturated soil condition and landslide in seconds. It is a parameter to describe failure process. Horizon boundary declivity is a broad in horizon boundary formed an angle toward the horizontal and assumed parallel with slope surface.Landsliding duration can be measured by way of landslide simulation to saturated soil sample through artificial rain with 50 mm hour-1 intensity up to landslide. Soil sample taken as a whole by pipe. This treatment consisted of 40o and 70o horizon boundary declivity and repeated 10 times. Soil sampling conducted at 4 locations divided by 2 locations with silt domination and 2 locations with clay domination. Beside that, qualitative observation performed of process and mass movement as well.The result of observation has shown that landsliding duration at 40o horizon boundary declivity is slower than 70o. Gravitation forces has characteristic of holding soil mass at 40o horizon boundary declivity, but at 70o horizon boundary declivity it will cause landslide. Medium texture will landslide faster than fine texture at 40o horizon boundary declivity. But at 70o horizon boundary declivity both of medium and fine texture will landslide together. Due to that 70o horizon boundary declivity dominated by gravitation force that pull soil mass to the downslope. While at 40o horizon boundary declivity, soil physics nature is still have a role, where fine texture have characteristic of sticky and medium texture have a quality of slick.Translational slides happen at 70o horizon boundary declivity so many times. While topples usually happen at 40o horizon boundary declivity. This cause of at 40o horizon boundary declivity soil physics nature still have a role of landslide, while at 70o horizon boundary declivity gravitation forces pull soil mass more dominant. But if it related with texture, translational slides usually happen at medium texture and topples happen at fine texture so many times. Landslide process at fine texture is preceded by cracks forming ended by topples. While landslide process at medium texture is preceded by smooth erosion on soil surface and soil liquefaction at upper side of horizon boundary because of the water is not able to penetrate beneath horizon.Key words: lansliding duration, horizon boundary declivity, texture

Abstract

Tailings, waste material from gold processing, contain heavy metals that are toxic such as mercury (Hg). One of the negative impacts is causing contamination of soil, developed through the accumulation of heavy metals. Phytoremediation is an alternative technology, using plant to clean heavy metal contaminated soil. A research, using Caladium bicolor, Paspalum conjugatum and Commelina nudiflora was then conducted as phytoremediation for contaminated soil. The research was conducted in the greenhouse using a randomized block design (RBD) with 3 factors and 3 replications. The first factor was percentage of tailings in the soil (10% and 20%). The second factor was the type of phytoectractor plants (C. bicolor, P. conjugatum and C. nudiflora). The third factor was the use of organic matter (with and without organic matter). The study was conducted in two steps, namely 1) phytoremediation, using C. bicolor, P. conjugatum, and C. nudiflora; 2) evalution of corn growth after phytoremediation. The results showed that Hg content in the soil containing 10% tailings (T1) was twice less than in the soil containing 20% tailings (T2). The addition of organic matter increased the potential for Hg absorption and consequently reduced content of Hg in the soil. C. bicolor, P. conjugatum and C. nudiflora decreased Hg content in the soil, and hence potentially used for phytoremediation. Of the three plants, C. nudiflora showed the highest Hg absorption. Decreasing content of Hg in the soil improved corn growth, as indicated by increasing height, number of leavs and dry weight.Keyword: Mercury (Hg), Hyperacumulator, Phytoremediation

Abstract

Land degradation in the Cassava causing damage to land, especially land due to the loss of part of the place. The loss of this part of the land causes a decrease in soil productivity, loss of the elements required burly plants, infiltration rate and water holding ability of soil is reduced, and the land use of opium. This condition will result in halted plant growth and decrease harvest. Various kinds of soil conservation activities has long been introduction by the government. However, results are still unsatisfactory. Not many farmers who adopt conservation technology, the government introduced the land, and land degradation continues.This research is to learn how different the various technical maintenance of the nature of the soil, the plants, and erosion and find out the pattern of land the right to increase the plant Cassava. Reduction in erosion rate occurred as a result of improvements to the land and the nature of plant growth.Research conducted in the Garden Experiments Brawijaya University in Malang. Ordo Alfisols including land, land and cycle 6 - 8%. Maintenance of land is done with the form of organic manure, and soil processing. Results of research shows that, technical maintenance of good soil is able to increase plant growth. As a result of improvements to decrease the growth of plants and limpasan level erosion surface. In the election technology, farmers choose tumpangsari treatment combination of manure and gulud as possible options.Keyword: land husbandry, cassava, land management, crops, erosion.
