Abstract

The role of tropical forests for maintaining environmental functions is decreasing due to the rapid changes to agricultural purposes. Agroforestry system is assumed to be an alternative system which reduces the negative impact of the conversion in term of maintaining the level of soil macrofauna diversity. This study was conducted at UB Forest within the period November 2017 to February 2018 by collecting soil macrofauna from 9 different land use types using hand sorting along with pitfall sampling for comparison. ANOVA and various diversity indexes were used (Shannon index, Pielu index, etc) to determine macrofauna structure and communities. Total soil C was examined using Walkley and Black method along with Particulate Organic Matter (POM) C fractionation approaches. Litter inputs were collected using a litter trap method, whilst in-situ litter were determined using destructive methods. Biplot and CVA multivariate analyses were adopted to determine the impact of different management on soil macrofauna diversity and structure. The result showed that conversion to agriculture practices reduced the structure, population and abundance of soil macrofauna as litter production, organic matter and soil C content decreased. The lowest abundance of individual soil macrofauna at monoculture system (PM) was reduced to 45 morphospecies compared to pine coffee agroforestry at the age of 4 (PK4:20 years after planting) system as much as 104 morphospecies. There was a strong relationship between litter thickness and the abundance of soil macrofauna. Both methods (Hand sorting vs Pitfalls traps), had a different ability for collecting soil macrofauna communities. Species occurs at rich or low organic matter input can be adopted as soil macrofauna bioindicator of changes on an ecosystem. Biplot and CVA methods can be used to distinguish and to cluster the impact of different management at various agroforestry systems.

Abstract

Nutrient loss in dry land through surface runoff and soil erosion is thought to dominate the watershed eutrophication. Conservation agriculture is expected to be able to reduce the nitrogen (N) loss into river systems. This study aimed to compare the N total input between conservation and conventional farming systems and to analyze N losses through surface runoff and soil erosion in conservation agriculture compared to conventional farming systems. The study was conducted at Agro-Techno-Park at Jatikerto, Brawijaya University from December 2017 to September 2018. The experiment was designed with three factors, i.e. (1) with and without biogeotextile, (2) No and conventional tillage, (3) application of four kinds of cover crop residues, with three replications. Results of the study showed that conservation agriculture was able to provide higher N inputs into the soil than conventional agriculture. The N loss through surface runoff was relatively low, ranging from 0.03 kg/ha to 0.45 kg/ha. N loss through erosion with conventional tillage and without biogeotextile reached 15 kg/ha to 32 kg/ha. No-tillage practices combined with the biogeotextile application significantly reduce N losses through soil erosion to only 0.3 kg/ha to 5 kg/ha. Conservation agriculture is one of the solutions to overcome the trade-off between the need for increased food production and environmental protection.

Abstract

Generally, Nickel mining was conducted by the open-pit mining method which caused change of soil physical, chemical and biological properties. Reclamation land often experienced various obstacles, including microclimate conditions that were not yet suitable, overburden chemical, physical and biological properties, difficulty in obtained ameliorant, and lack of topsoil. Topsoil that was used for post-mining reclamation land activities was obtained from the soil is not yet mined locations (natural soil). This study was aimed to determine differences in soil characteristics (soil physical, chemical and biological properties) on post-mining reclamation land with natural soil without topsoil. The research used survey methods conducted on post-mining land of PT. INCO. Soil samples were taken at 2 locations, namely, the location of post-mining reclamation (Harapan) and location that had not mined but the topsoil had peeled to a depth of ± 1 meter (Shelly). The results showed that the soil physical and biological properties at Shelly location were relatively better than those at Harapan location. The soil at Harapan and Shelly locations had available P content and exchangeable-Na was low and exchangeable-Ca was very low. Exchangeable-Mg was high at Harapan, while at Shelly was low-moderate. The exchangeable-K content of the soil in the Harapan location was moderate than Shelly location. The soil at Harapan location had a very high Base Saturation (BS) with a pH of 6.7 than Shelly location had high BS with a pH of 5.8. It is necessary to improve post-mining reclamation land management.

Abstract

Pollution of agricultural land by tailings from the Artisanal and Small-Scale Gold Mining (ASGM) can increase the concentration of mercury (Hg) in plant tissue thus; it will endanger the health of humans and animals that consume it. This study aimed to determine the amount of Hg taken up by maize plants on an inceptisol contaminated with tailings from amalgamation and cyanidation processes of small-scale gold mining. A field experiment was conducted at the experimental field of Faculty of Agriculture, University of Mataram by using a factorial randomized block design consisting of two factors, namely: (1) tailings (L), and (2) ) fertilization (N). The results indicated that adding amalgamation and cyanidation tailings increased the physical and chemical fertility of the soil studied but caused Hg pollution. Most of the Hg in plant tissue was concentrated in the roots of the plants. The content of Hg in the plant shoot was above the threshold value of mercury allowed in plants. The NK33 variety of maize can be categorized as a mercury tolerant plant as the plant grew well in a mercury-contaminated soil.

Abstract

This study aimed to determine the status of soil damage in Pitu District, Ngawi Regency. The study was conducted in a descriptive exploratory with survey methods. Determination of site sampling was done by purposive sampling, based on distribution or division and land use categories from the results of map overlays. Assessment of soil degradation potency was based on land units from the uniformity of the soil, rainfall, slope, and land use map. Land units resulting from overlay were scored based on the results of multiplication of weights and soil, slope, rainfall, and land use ratings. Total score indicates soil Degradation Potency (SDP). Assessment of soil degradation status was done through matching and scoring. Field observation results were matched with the standard criteria of soil degradation from Indonesian Government Regulation No. 150 of 2000. Each parameter was scored, then the total score was used to determine soil degradation status. Soil degradation potency in Pitu District, Ngawi Regency is PR II (Low) at LMU (Land Map Units) 1, 3, 4, 5, and 8, and PR III (Moderate) at LMU 2, 6, 7, 9, and 10. Soil degradation status in Pitu District, Ngawi Regency is slightly degraded at all LMU, with limiting factors, namely texture, bulk density, total porosity, and permeability.

Abstract

In addition to tree planting activities, finding an alternative method to restore degraded land in semi-arid areas is necessary, and direct seeding of woody plants might be an alternative option. The objectives of this study paper were (1) evaluate the growth, biomass and survival of different woody plant species established through direct seeding in a semi-arid degraded land; (2) identify woody plant species that could be further used for restoration of degraded lands. To achieve the objectives eight woody plant species seeds were gathered, their seeds were sown in a degraded land, in a randomized complete block design (RCBD) (n=4). Data on germination, growth and survival of the different woody plants were collected at regular intervals during an eleven-month period. At the end of the study period, the remaining woody plants' dry biomasses were assessed. One-way analysis of variance (ANOVA) was used for the data analysis and mean separation was performed using Fisher’s least significant difference (LSD) test (p=0.05). The result revealed significant differences on the mean heights, root length, root collar diameters, root to shoot ratio, dry root biomasses and dry shoot biomasses of the different species (p < 0.05). There were also variations among species in their germination, dry biomasses and survival. The survival of the woody plants was inversely correlated with air temperature. Of the species studied, four tree species, Dodonaea angustifolia, Vachellia tortilis, Vachellia seyal and Vachellia nilotica, were successful in growing in the degraded land; and therefore, we recommend these for restoration projects

Abstract

Land resources availability has been declining due to the rapid development of the industrial, residential, and even tourism sectors in all regions, including Batang Kuis Subdistrict, Deli Serdang Regency of North Sumatra Province. The declining of land resources in Batang Kuis Subdistrict has a strong relationship with the factors causing rapid and dynamic development of Kualanamu Airport located at the east side of the sub-district. Regional development causes land conversion and urban development that impacts on carrying capacity of the land. Therefore, the objective of this study was to determine the relationship between land use and land carrying capacity of Batang Kuis Subdistrict in 2010 and 2017. Data used for this study consisted of primary data by Google Earth satellite imagery of Batang Kuis Subdistrict and secondary data of population and area per village in 2010 and 2017. The analysis used for this study was a quantitative analysis by calculating Land Carrying Capacity (LCC) and spatial analysis by mapping the land area that has been developed in two years with a unit of analysis at the village. Results obtained from this study were land carrying capacity table and the land area maps of Batang Kuis Subdistrict for 2010 and 2017. The highest value of land consumption per capita referring to Yeates dan Garner standard was observed at Sena, Sidodadi, and Mesjid Villages in 2010 and 2017. The main factor is easy accessibility since the development of Kualanamu Airport.

Abstract

Rangsang Island is home to more than 48,000 residents. Climate change has been a critical issue to the Island and threatened the existence of the inhabitants. This study is proposed to identify the zone of the coastal area of Rangsang Island which is vulnerable to climate change. By mapping coastal vulnerability index (CVI) of the island, it is expected to be a reference of local government in planning their spatial management. The method of this study was by a direct survey for collecting data of geomorphology, beach elevation, sea level rise, tidal fluctuation, significant wave height, and changes in the coastline. To determine CVI, each parameter is divided into 5 categories and given a value level: 1 for very not vulnerable, 2 for not vulnerable, 3 for moderate, 4 for vulnerable, and 5 for very vulnerable. The results show that most villages on the island are classified as highly vulnerable to climate change, namely 9 villages. Even 2 villages are threatened very high risk because the village has CVI more than 12.5. Only 6 villages whose territory has moderate vulnerability index. Vulnerability level of coastal Rangsang Island is strongly influenced by geomorphological variable and coastal elevation. In addition, the variable coastline changes and sea level rise also contributed to the vulnerability index of the Island.

Abstract

A series of experiments in a plastic house were carried out to test the accumulation of Pb metal in Chinese cabbage and bean plants from the application of several Pb sources. The research method used was a split-plot design with the main plot was the application of Pb source consisting of A1 = pesticide (99 mg Pb/kg), A2 = fertilizer (21 mg Pb/kg), A3 = Pb(NO3)2 (50 mg Pb/kg) and A4 = control (without the application of Pb), and the subplot was the vegetable crops consisting of B1 = Chinese cabbage (Brassica rapa) and B2 = bean (Phaseolus vulgaris). The results of the experiment showed that the Pb content in the shoots of Chinese cabbage and bean plants that were previously sprayed with pesticide was significantly 231.02% (Chinese cabbage) and 257.18% (bean) higher than control plants. Meanwhile, the largest Pb concentrations in the roots of Chinese cabbage and bean plants were obtained in plants applied with Pb(NO3)2. Compared to the control treatment, there was an increase in Pb concentration by 206.32% in the roots of Chinese cabbage plant and by 310.03% in the roots of bean plant which were applied with Pb(NO3)2. Pb concentrations of Chinese cabbage which were given fertilizer increased by 14.86% in the shoot and 30.59% in the root, while those in bean increased by 10.74% in the shoot and 98.77% in the root. Pb concentrations in Chinese cabbage and beans that were given fertilizer were not significantly different from control plants. These results indicate that the application of pesticide and fertilizer containing Pb results in Pb accumulation in the plant shoots and roots as well as in the soil.
