Abstract

Indonesia is one of the countries with the largest Au deposited. Gold mining has been the backbone of Indonesia’s economy. However, Indonesia also faces huge problems of Artisanal and Small Scale Gold Mining (ASGM) in a number of areas of Indonesia. A number of problems follow this Au mining method, including environmental, social and economic problems. Green innovation and technologies are needed to solve the problems. To date, Au agromining has been considered as a technology that can solve the numerical problems of Au conventional mining in the sector mentioned before. Gold agromining also has been proposed as a solution for the ASGM problem in Indonesia. However, until now, there have been no reports on the use of Au agromining technology in Indonesia. In fact, agromining research has been very advanced and is considered very prospective. This paper outlines the potentials of Au agromining to be implemented in Indonesia to overcome the social and environmental problems of ASGM.

Abstract

The massive exploration and production well drillings in Nigerian oilfield indicate the demand for drilling fluid supplements such as baryte, in managing over-pressured formations and preventing hazardous blowouts. The underdevelopment of Nigerian solid minerals has created a wide gap between the demand and supply of the local resource, whereas there exist some assertions that the Nigerian baryte quality is below the American Petroleum Institute, API, standard. This study aimed at testing and evaluating qualitatively, based on API standards, some baryte ores from the Benue area, Nigeria, to establish their usefulness or otherwise in oilfield drilling operations. General field studies and sampling with laboratory studies were done including flame tests, X-ray Diffraction and X-ray fluorescence, to confirm mineralogy and chemical compositions of the barytes respectively and very importantly, the API tests prescribed for drilling grade barytes were carried out. The results showed impressive quality barytes with a specific gravity range from 4.10 to 4.49 and concentration of alkaline earth metals as calcium, Ca, 20mg/kg to 48mg/kg, particle sizes processed within API standard requirement, and the weight percentage of BaSO4 composition of the ores ranged from 93.55% to 99.61%.  There were no significant impurities of threat such as carbonates, iron ores, silicates and sulphides. The estimation of reserves and proper development of the resource is highly recommended as the quantity and quality might enhance the sustainability of local drilling grade baryte supply and save Nigeria the current huge capital flight and other plights

Abstract

The present study assessed the acceptability of the rehabilitation efforts conducted by the University of the Philippines Los Baños (UPLB) Bioremediation Team in an inactive mined-out area in Mogpog, Marinduque, Philippines from 2006 to 2016. A researcher-made semi-structured questionnaire was used to interview key informants, like members of the local government unit (LGU) of Mogpog, Marinduque, head of the Provincial of Environment and Natural Resources Office (PENRO), and selected residents of Barangay Ino and Capayang near the mining site. The selection of the respondents (n=112) was done through a stratified random probability sampling among residents ages 20 years old and above to determine their awareness and knowledge about the mined-out area before and after its rehabilitation. Interview with key informants revealed different functions towards the rehabilitation of the mined-out area. Results also showed that 59% of the respondents were aware of the rehabilitation efforts made on the site, and 98% of them strongly agreed on the presence and harmful effects of toxic chemicals in the area.   They also strongly agreed that the rehabilitation efforts had a positive impact on the environment, biodiversity and the community nearby. Interventions implemented by the government and other agencies are likely to succeed with the help of the nearby community and therefore, the same community can also be the best judge to determine the acceptability of the interventions.

Abstract

Mining activity may potentially produce acid mine drainage (AMD), which has relatively high acidity and dissolved heavy metal concentrations. Constructed wetlands is one of the AMD management methods in which organic matter (OM) plays a very important function in reducing the concentration of heavy metals in AMD through absorption and precipitation processes. Three types of OM (empty fruit bunches of oil palm, chicken manure and water hyacinth) and five levels of OM (0, 10, 20, 30 and 40 Mg ha-1) were applied to reclaimed-mining soils (RMS) in an incubation study. A batch experiment was then performed to measure the effect of OM application on the maximum sorption capacity (Qmax) of iron (Fe) from the AMD onto the mixed soil-OM. The application of OM resulted in increases in soil pH, carboxylic groups, and total functional groups, in which these increases varied based on the types and amounts of OM application. This study also revealed that OM application resulted in increasing Fe sorption. The application of OM increased Qmax values from 2077 to 2348-3259 mg kg-1 (water hyacinth), to 2607-3635 mg kg-1 (chicken manure), and to 2219-2992 mg kg-1 (empty fruit bunches of oil palm). Increasing these Qmax values may ascribe to increasing functional groups of the RMS with OM application. The results prove the importance of OM in controlling the sorption of Fe from AMD onto soils.

Abstract

The identification of potential habitats of the largest and smallest flowering parasitic Rafflesia in the Philippines is a prerequisite in conservation of species and preservation of their habitats which have been being degraded due to anthropogenic activities and climate change. This research aimed at revealing the possible habitat suitability for Rafflesia schadenbergiana Göppert ex Hieron and Rafflesia consueloae Galindon, Ong Fernando throughout the Philippines using Geographic Information Systems (GIS). The selection criteria in this research were based on four parameters (elevation, annual rainfall, temperature, and land use / land classification) identified during the extensive literature review. The generated map shows that the optimal growth of the Rafflesia schadenbergiana can be observed with a temperature range of 20–22°C while Rafflesia consueloae can thrive within 24°C to 25°C. The importance of these criteria was evaluated using a pairwise comparison method and the final weight was computed for each criterion. Setting up of the values suiting the subject species was followed by weighted overlay analysis. The final output is the distribution and habitat suitability of the subject species.

Abstract

Coal fly ash (CFA) is a coal-burning by-product containing macro and micronutrients, and it is the potential material for improving available P in Ultisols. Phosphate-solubilizing bacteria (PSB) play a role in phosphorus solubilization. This study aimed at elucidating the potential use of phosphate-solubilizing bacteria to optimize the use of coal fly ash for increasing soil available P. This study was conducted in two stages, namely isolation of indigenous PSB from an Ultisol and application of the PSB and CFA to improve soil available P. Five indigenous PSB isolated from the soil had the ability to dissolve phosphate. Isolate B5 could dissolve 9.89 ppm P and had a 99.57% closeness to Pseudomonas stutzeri. The application of 20 and 40 t CFA ha-1 increased the soil pH by 4.2% and 7.2%, respectively. Increasing the dose of CFA decreased the content of available P by 50.6%. However, the combination of PSB and 20 t CFA ha-1 increased soil available P, plant growth, plant dry biomass, and P-uptake by plant.

Abstract

Results of previous research have proven that soil organic matter (humic and biochar compounds) can increase and maintain soil fertility and protect environmental resilience. The purpose of this study was to increase the abundance of microorganisms in young soil (regosol) with biopelet fertilizer composed of a combination of biochar, chicken manure, and shrimp waste to improve soil fertility. The experimental design used was a randomized block design with two factors, namely the composition and dosage of biopelets. The compositions of biopelet were 70% biochar, 15% chicken manure and 15% fish waste (B1); 50% biochar, 25% chicken manure and 25 % fish waste (B2): and 20% biochar, 40% chicken manure and 40% fish waste (B3). The dosage used was four levels (0, 2.5, 5, and 10 t/ha).The results showed that the application of biopelet fertilizer to the regosol soil reduced soil pH from slightly alkaline to near neutral, and the addition of up to 10 t biopelet/ha increased soil organic C content from 1.17% to 1.72%, as well as increasing the availability of N, P, and K nutrients. Improvement in pH, organic-C, and soil macronutrients was followed by an increase in the abundance of soil microorganisms, especially bacteria.

Abstract

Earthworms (Pheretima sp.) could survive under abiotic stress soil conditions. Furthermore, their activities as ecosystem engineers allow for the creation of soil biostructures with new characteristics. Therefore, this study aimed to investigate the effect of the abundance of Pheretima sp. on the aggregate size, physicochemistry, and biology of the topsoil from the nickel mining area of Southeast Sulawesi, Indonesia. It was carried out by first grouping their abundance into zero, two, four, six, and eight individuals per pot and then carrying out tests. The Pheretima sp. were then released onto the surface of the topsoil and mixed with biochar that was saturated with tap water in the pot overnight. The results showed that the abundance of the species had a significant effect on the size class distribution, and aggregate stability of the soil. Furthermore, the size of the soil aggregates formed was dominated by the size class 2.83 - 4.75 mm under both dry and wet conditions. Under dry conditions, three size classes were found, while under wet conditions, there were five size classes. The results also showed that the highest and lowest stability indexes occurred with zero and eight Pheretima sp., respectively. Furthermore, the abundance had a significant effect on pH, organic C, total N, CEC, and total nematodes. However, it had no significant effect on the total P, C/N ratio, total AMF spores, and flagellate. The highest soil pH occurred with zero Pheretima sp., while with six and two members of the species, the total nematode was at its highest and lowest populations, respectively. Therefore, it could be concluded that the species was able to create novel conditions in the topsoils at the nickel mining area that were suitable for various soil biota.

Abstract

This study was conducted to determine mercury contamination contained in soils in Kalirejo sub-district, Kulon Progo, Indonesia. This contamination occurred as a result of traditional gold mining activities that used the amalgamation method of mercury. Soil samples were collected from 6 sites; one site was located in an uncontaminated location, and 5 sites in contaminated soil were taken from 10 meters distance from the tailing ponds. Samples were collected from each site at 30, 60, and 90 cm depths. Mercury concentrations in each sample were measured according to the US EPA method, using Mercury analyzer type VM-3000. Mercury concentrations in uncontaminated area at 30, 60, 90 depths were 0.19 mg/kg, 0.02 mg/kg, and <0.0001 mg/kg respectively. These values did not exceed the quality standard according to Government Regulation No 101 The Year 2014 concerning Hazardous Waste Management of 0.3 mg/kg. Meanwhile, mercury concentrations around the tailing ponds were 0.30 to 22.51 mg/kg, which exceeded the quality standard.
