Abstract

Rice has become the leading food commodity in Indonesia, with total production reached +54.60 million tons in 2019. However, the production tended to decrease by around 8% from 2018 to 2019, while the rice consumption increased by +1.53 tons. This study aims to develop a rice production estimation model using the soil-vegetation index transformation (MSAVI and SAVI) and soil physical properties, which has the advantage of being faster, cheaper, and more accurate than conventional methods. The soil physical properties were taken based on soil mapping units and analyzed with soil physical parameters. The results showed strong relationships between rice productivity - soil physical characteristics and rice productivity – MSAVI and EVI with r values of 0.97, 0.83, and 0.74, respectively. The soil physical properties have a better coefficient of determination and accuracy than soil-vegetation index. The prediction model of rice production by soil physical properties is formulated inward γ = -8.96+0.01 (Top Soil Sand) + 0.01 (Top Soil Silt) + 6.28 (Bulk Density) - 14.07 (Penetration) - 0.13 (Sub Soil Permeability). There is no difference in the productivity value between model and laboratory analysis result. These results indicate that the rice yield prediction model can be used for estimation purposes.

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

Stone quarrying has a considerable impact on land, water, air, natural resources, and social welfare. The objective of this study was to assess communities’ awareness of the environmental and social impacts of stone quarrying in Farta woreda, Northwest Ethiopia.  The study used a cross-sectional research design. The 359 sample respondents were randomly selected. Both quantitative and qualitative data were collected using household surveys, interviews, focus group discussions, and field observation methods. A binary logistic regression model was done to identify the independent variables of communities unaware of the impacts of stone quarrying. 62.7% and 57.38% of the surveyed households had aware of the impacts of stone quarrying social and environmental, respectively. Age of households heads from 31 - 40 (AOR = 1.272, 95% CI = (0.598-2.708), from 41 -50 age (AOR = 2.152, 95% CI = (0.947- 4.889), from 51- 65 age (AOR = 3.207, 95% CI = (1.405-7.321), Educational level of household heads, elementary school (1-8) (AOR = 2.985, 95% CI = (1.523-5.852), secondary school and above (AOR = 3.794, 95%  CI = (1.841-7.820),  Income of household heads from 10000 to 20000 birr (AOR = 2.254, 95% CI = (1.236 - 4.109), Income less than 1000 birr (AOR = 2.493, 95% CI = (1.419 - 4.380) were associated with unaware community on the impact of stone quarry. To solve present and future environmental and social problems, the study woreda Environmental Protection Offices should enhance communities’ awareness through awareness creation and environmental education program.

Abstract

This study aimed at determining the community structure and diversity of soil bacteria in several land-use changes as an environmental bioindicator. This research was conducted in areas of intensive agriculture (PI), monoculture abandoned old-coffee plantation (KTT), mixed-young coffee plantation (HLS), and secondary forest/reference site (RS) in UB Forest (UBF) area, Malang, Indonesia. Soil samples were taken as a composite at three different points in each area using a soil ring at a depth of 0-20 cm. The 16S rRNA gene was used to determine the community structure, species richness, diversity, and ecological index (Chao1, Shannon, Simpson, ACE) of soil bacteria using the NGS approach. Statistical data were analysed using R and QIIME software. The community structure of soil bacteria at the phylum level displayed the same pattern in all study sites where Proteobacteria, Acidobacteria, Actinobacteria, Chloroflexi were the dominant groups. Conversely, the bacterial composition showed differences between study sites at the genus level. Alpha diversity in agricultural areas (PI, KTT, and HLS) was higher than forest area (RS), but it was not followed by bacterial beta diversity. The distinct soil bacteria composition and diversity were influenced by the physicochemical of soil properties in the studied area. Therefore, several bacterial taxa suggested being a potential bioindicator of forest soil degradation due to land-use change in this study. Soil bacterial indicators can be utilized to evaluate or monitor alteration of soil quality in terms of forest restoration or rehabilitation.

Abstract

The purpose of this research was to study the growth response of pokem (Setaria italica), which was inoculated by the arbuscular mycorrhizal fungi (AMF) from the tailings area. The method used in this research was a completely randomized design of factorial pattern. The factors consisted of AMF types (M)(M0: non-mycorrhizal, M1: Claroideoglomus etunicatum BGR, M2: C. lamellosum B1107S, M3: C. etunicatum L3101D), and inoculum density (I) (I: 5 g, II: 10 g per pot of planting media) with 8 replicates. The source of inoculum C. lamellosum B1107S and C. etunicatum L3101D originated from tailings in the gold mining area of Timika. The results showed that inoculation of C. etunicatum L3101D could increase the plant growth better than C. etunicatum BGR and C. lamellosum B1107S. Significant growth occurred on the parameters of the height of the plants, leaf area, dry weight and fresh weight of the plants, relative growth rate, and phosphorus absorption by the plants. The amount of nitrogen tended to decrease with AMF treatment, but it was not significant, whereas K has insiginificantly increased. The propagule density treatment increased plant growth on all parameters. The best growth occurred if the type C. etunicatum L3101D was inoculated with 10 g of propagule per planting media.

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 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

Due to the massive amounts of freshwater consumed in dairy industries, as a result, thousands of liters of wastewater were produced as one liter of milk produces 10 liters of wastewater which represents a major threat to the surrounding environment and aquatic life. The application of a promising technology called “effective microorganism (EM)” was the key solution due to its low operating cost, low technology, and eco-friendly condition. Three different effective microorganisms were used, such as Bacillus bacteria (EM1), Staphylococcus bacteria (EM2), and EM stoste + Molasses (EM3). EM1 and EM2 were isolated from the dairy wastewater by using streaking for isolation on an agar plate process, while EM3 was prepared by mixing 12 % EM stoste, 6% molasses, and 82% distilled water. A laboratory pilot consists of aeration and final settling tanks, both tanks followed by an activated carbon filter. Four trials were performed, the first trial was without any EM, the second trial was adding EM1 with a dose of 50 ml to the aeration tank, the third trial was EM2 with a dose of 50 ml to the aeration tank, finally adding EM3 with a dose of 30 ml to the aeration tank. Results showed that using Bacillus bacteria (EM1) was the most effective trial as it was effective in reducing TSS (total suspended solids), BOD (biological oxygen demand), COD (chemical oxygen demand), TN (total nitrogen), and TP (total phosphorous) concentrations by removal efficiency of 93%, 96.2%, 95.9%, 94%, and 64%, respectively which were below the limitations of the Egyptian code for reuse for irrigation purposes.

Abstract

Mining activities specifically Coal Mining have been long testified to be one of the major contributing factors to environmental crisis, with Acid Mine Drainage (AMD) as one of the leading indicators. The purpose of this study was to assess the potential of AMD generation from neutralized coal mining tailings. In order to achieve the ultimate objective of the study, analysis of chemical composition and mineral content of the tailings using XRF (X-Ray Fluorescence) and XRD (X-Ray Diffraction) respectively, lastly, a static analysis such as ABA (Acid Base Accounting) and TCLP (Toxic Characteristic Leaching Procedure) were also conducted. The results have shown that the studied tailing samples had relatively higher Acid Potential (19 kg CaCO3/t to 20 kg CaCO3/t) versus the Neutralizing Potential (NP) (14 kg CaCO3/t to 18 kg CaCO3/t). It was also found that the Net Neutralizing Potential Ratio (NNPR) is less than zero (-1.5 kg CaCO3/t to -5.40 kg CaCO3/t which indicates that the tailings have the potential to generate acid. The low concentration of CaO indicates acidic potential of the samples because CaO is a buffering mineral. Based on the results of the study, it was concluded that Mine Tailings has the potential to generate acid; therefore, the contamination to the nearby watercourses is extremely possible if necessary remedial actions should be considered.

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.
