Abstract

Environmental damage due to mining activities has now become an international issue as its regional and global assessments are widely reported from various mining commodities. Nevertheless, only a few studies have published environmental damage on detailed and local scales. This research was designed to assess the environmental damage induced by traditional mining in the Wungkal Hills, Yogyakarta on these scales by a descriptive exploratory method and quantitative measurement in the field. The mining commodity is clay, which is used as the raw material of bricks and tiles. The observed parameters included abiotic, biotic, and cultural components. The level of damage to abiotic and biotic components due to traditional mining fell into the category of critically damaged. It is attributable to faulty mining procedures that do not incorporate ecological aspects. Changes in landscape, slope, the height of excavation cliff, and the absence of vegetation lead to physical damages by extreme erosion and trigger landslides. Culturally, there was no negative impact on society. Lack of ecological understanding underlays public ignorance of the damage that the traditional mining activities had caused. In the study area, the environmental damages were critical both on detailed and local scales. Reclamation and revegetation based on the agroforestry concept are recommended for the restoration of post-mining land productivity

Abstract

Almost all developing countries satisfy their energy requirements from firewood. In Ethiopia majority of the rural population relies on biomass energy sources for every energy necessities. Fuelwood accounts for about 78 % of the total energy needs, whereas animal dung and crop residue share 12 % and nine percent, respectively. Almost all of the firewoods are collected from natural forests and few of them from homestead trees. Chronic drought, land degradation, and loss of soil fertility that are positively correlated with low livestock and crop productivity are extensions of deforestation for firewood. Heavy dependency on biomass fuel in Ethiopia has resulted in fast deforestation, desertification, climate change, global warming and finally decrease in agricultural productivity. Therefore the adoption of biogas technologies has great potentials to supply low-cost energy and results in less dependency on firewood. To improve such adverse socio-economic and ecological costs, interventions like improved biogas technologies, raising community awareness on deforestation, and utilization of alternative energy technologies are recommended to conserve natural forests.

Abstract

Amalgamation in the processing of community gold mines may leave slurry waste with the potential for heavy metal contamination of the environment. Technical studies for handling these wastes are very necessary to process the waste using a simple and applicable manner in the community. The purpose of this study was to examine the coagulation-adsorption technique of liquid waste from the amalgamation process. Slurry waste samples from the amalgamation process were collected from amalgamation sites in Boto Village, Wonogiri regency which had the highest Hg and Pb levels in the slurry. The coagulation-adsorption process is carried out by a continuous process with the gravitational flow because the area of the amalgamation process has a steep slope.  Coagulation of particles in the slurry used two kinds of natural ingredients, i.e. papaya seed, and moringa seed extracts.  The adsorption was conducted using two types of minerals, i.e. Ca-bentonite and zeolite which had been activated. The results of this study showed that the coagulation process was a simple process to purify amalgamation slurry waste and reduce the levels of Fe, Mn, Hg, and Pb metals.  Then the following step by using the absorption process to produce clear water from amalgamation liquid waste and reduce the levels of Fe and Mn metals. Coagulation using papaya seeds might purify amalgamation slurry waste and reduce heavy metal content of Fe 99.996%; Mn 99.994%; Pb 100%; Hg 100%. Based on these results, the Hg and Pb metals were metals that were very easy to settle. Adsorption on the liquid result of the coagulation process using unactivated zeolite reduced the metal content of Fe> 99.40% and Mn> 88.69%.

Abstract

Direct seeding is considered as an option for afforestation programs to rehabilitate degraded lands. However, scant knowledge is available on the effect of seed sowing techniques on the germination of different woody plants in a semi-arid degraded area. Therefore, the objectives of this study paper are 1) to evaluate the effects of broadcasting vs seed bury on the germination of 15 different woody plant species in a degraded semi-arid area 2) to select woody plants that can result in higher germination percent in the field for restoration projects. To achieve the objectives, a study was carried out in the field, with a randomized complete block design (RCBD). One-way ANOVA, t-test and descriptive statistics were used to analyze the data. The result indicated that the average germination percent for buried and broadcasted seeds were 18.1% and 5.2%, respectively. Among the broadcasted species seeds, Schinus molle achieved the highest germination (23.3%) while Terminalia browni achieved the lowest germination (0.25%). Among the different species seeds that were buried, Dolanix regia achieved the lowest germination (1.5%) while Sesbania sesban resulted in the highest germination (64%). The t-test result revealed a significant difference in the mean germination of the broadcasted and buried seeds (p<0.05). The ANOVA result also revealed significant differences in the germination of the different families of the species. For most of the studied species (86%), seed bury has resulted in higher germination percent relative to the broadcasted seeds. Therefore, it is recommended that in semi-arid degraded land, it could be better to apply seed bury than the broadcasting when there is an objective to use direct seeding for afforestation.

Abstract

Tailings are the parent material residues resulted from a separation process of valuable minerals containing copper, gold and silver. This separation process is carried out mechanically by destroying copper, gold and silver rocks on the Grasberg plateau. However, in the production process of tailing materials from Wanagon and Aghawagon rivers, there was also non-tailing material mixed with tailing materials. This condition cannot be avoided due to high and intensive rainfall so that non-tailing material from an ex-mine excavation in the form of overburden can flow naturally through the river flow system from the highlands to the lowlands of ModADA. Acid Mine Drainage (AMD) is one of the important impacts of mining activities that must be managed because it has an impact on the aquatic environment or groundwater, and once it has been formed it will be difficult to stop unless one of the components runs out. The study was carried out from 2005 to 2014 at several representative locations in ModADA included inactive tailings at MP 27 and MP 21, as well as active tailings at WA 225, WA 185, and WA 160. The average heavy metal content in WA 225, WA 185, WA 160 included in the criteria of class C, namely As (> 33 mg/kg), Cu (> 150 mg/kg), Pb (> 130 mg/kg), and Zn (> 460 mg/kg). Another heavy metal categorized as class B was Cd (1-5 mg/kg), while class A consisted of Cr (<43 mg/kg), Hg (<0.2 mg/kg), and Ni (<23 mg/kg). At WA 185, The ANC/MPA ratio at WA 185 < 1.5 was 0.97 (0-20 cm) and increased slightly to 1.59 (20-40 cm). The ANC/MPA ratio < 1.5 shows a higher acid-forming ability (MPA) than the ability to neutralize acid (ANC). The average heavy metal content in MP 27 is lower in concentration, except Cu which included in class C (> 150 mg/kg) which is similar to the host rock mined and involved in the tailings flow from MP 74. The Cu concentration at MP 21 decreased drastically, except for As which included in class C (> 33 mg/kg). The ANC/MPA ratio at MP 21 was 1.92 (0-20 cm) and slightly increased to 2.22 (20-40 cm), while MP 21 has the ANC/MPA ratio at 12.61 (0- 20 cm), and decreased to 4.34 (20-40 cm).

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

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

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

There is a long-standing debate on the relationship between land-related investments and tenure security and most studies in this sense fail to reach a concrete conclusion because of their focus on one side. This paper has employed a separate analysis for short-run farm investments as represented by spending on farm inputs and long-term investments as represented by hours spent on stone bund building in an attempt to solve this problem. Two Tobit models were estimated to analyze household level determinants of land-related investment decisions by smallholder farmers in Ethiopia and its tenure security implications. The findings revealed that there is no meaningful and significant relationship between tenure security and land-related investments decisions. Poverty status, rather, was found to exert significant negative pressure on investment decisions. Productivity, livestock holding, communal conservation around plot and participation in local government activities are found to be the major determinants of land investments.
