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 availability of P in acid soils may be raised through the application of phosphate solubilizing fungi (PSF). Coal fly ash (CFA) that has a high pH and contains a relatively high P may also be used to raise the availability of P in acid sois. The purpose of this study was to explore the possible use of CFA and PSF in a biochar-compost carrier to improve the availability of P and plant growth in acid soil. Combined applications of two PSF isolates (Aspergillus oryzae = F1, and Neosartorya fischeri = F2) carried in three levels of biochar-compost  (80% biochar + 20% compost = B1, 70% biochar + 30% compost = B2, and 60% biochar + 40% compost =B3), and two doses of CFA (60 t/ha = C1, and 80 t/ha = C2) were tested in this study through two experiments. The results of experiment 1 (laboratory experiment) showed that the application of N. fischeri carried in 70% biochar + 30% compost combined with 80 t CFA/ha (F2B2C2 treatment) significantly increased the available P more than other treatments. In comparison with control,  the increase of soil available P content ranged from 13% in the F1B1C1 treatment (A. oryzae in 80% biochar + 20% compost combined with 60 t CFA/ha) to 101% in the F2B2C2 treatment (N.fischeri in 70% biochar + 30% compost combined with 80 t CFA/ha). The results of experiment 2 (glasshouse experiment) showed that the highest dry weight of maize shoot was obtained by the F2B2C2 treatment that increased 123% compared to control. The highest P uptake by maize was obtained by the F2B2C2 treatment (N. fischeri in 70% biochar + 30% compost combined with 80 t CFA/ha).

Abstract

Acid mine drainage (AMD), produced when sulfide minerals are subjected to oxygen and water, is one of the major issues in mining industries. Without proper management, AMD's release to the environment would cause seriously prolonged environmental and health issues, such as increases soil acidity and reduces water quality due to extremely low pH, high sulphate concentration, and heavy metal solubility. AMD treatments are divided into two categories, i.e., active treatment, conducted by applying a chemical to the AMD to neutralize pH and precipitate heavy metals; and passive treatment, which relies on biological and biochemical processes. The active treatment may provide an immediate effect, but costly and yet sustainable; meanwhile, passive treatment takes time to establish and to generate an effect, but it is more economical, sustainable, and environmentally friendly. The wetland system is an example of passive treatment. Therefore, this review focuses on passive treatments, especially the selection of organic materials used in constructed AMD wetland treatment. Organic materials play a central role in the wetland system, i.e., to chelate metal ions, remove sulphate from the solution, increase pH, and growth media for microbes, especially sulphate reducing bacteria (SRB) and plants are grown in the system. Overall, organic materials determine the effectiveness of the wetland system to neutralize AMD passively and sustainably.

Abstract

Degradation of soil functions in storing and cycling nutrients may be related to topography and land-use change. The research aimed to analyze the impact of land-use changes and slope positions on soil function in nutrient stock within Kalikungkuk micro watershed of East Java, Indonesia. Four different land-uses such as vegetable crops, agroforestry, shrub and forest were selected with three slope positions (e.g. ridge, slope, and valley), and three replications of each. Soil samples were collected at 0-10, 10-30, 30-50, and 50-100 cm depth of soil. Variables measured included soil properties (e.g. bulk density, soil texture, pH, CEC, soil nutrients). Slope positions impact on differences in soil physical (i.e. soil bulk density, soil texture) and chemical (i.e. total N, exchangeable K) properties. In addition, forest conversion to other land-uses (i.e. agroforestry, shrub, vegetable crops) decreased soil nutrient concentration (i.e. total C, total N, Ca, Mg, Na), and consequently resulted in degradation of soil nutrient stocks of especially C and N. The strong positive correlation between soil nutrient stock (e.g. C and N) and vegetation cover such as canopy cover, basal area, and litter (r = 0.63 – 0.78, r table 1% = 0.39) showed the benefit of biodiversity in maintaining soil function on the nutrient stock.

Abstract

Sand mining activities in Pasir Sakti District, East Lampung Regency, have changed the landscape and the allotment of land around it. The former sand mining area now becomes large puddles that are not utilized. This study aimed to analyze the suitability of water quality in ex-sand mining areas for tilapia (Oreochromis niloticus) culture. Observations were carried out at three stations in January-October 2019. Water quality measurements were performed to check water depth, clarity, temperature, current, dissolved oxygen, pH, salinity, nitrate, phosphate, iron, sulfate, and phytoplankton density. Analysis of suitability for aquaculture was carried out using weighting and scoring methods. Based on the results of the suitability analysis, the scoring result of the sand mining land for O.niloticus culture was in the range of 64% -68%. This score is classified as marginally suitable. The parameters with low scores are clarity, dissolved oxygen, temperature, pH, ammonia, phosphate, and iron (Fe) concentration parameters. Meanwhile, salinity, nitrate, sulfate, and phytoplankton density indicate conditions that are suitable for aquaculture. Therefore, severe treatment is needed to improve water quality to make it ideal for O.niloticus culture.

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

Cadmium (Cd) is a harmful metal for paddy soil that is affected by inorganic fertilizer, pesticides, and industrialization. This study aimed to investigate the Cd contents in paddy soil, plant tissue, and grain, as well as the spatial distribution of potential Cd contamination. This study was conducted in Sragen Regency on paddy fields with different management, i.e., organic paddy fields, conventional paddy fields (Alfisols, Entisols, Inceptisols, and Vertisols), and paddy fields that often use wastewater (textiles, batik, and sugar factories) for irrigation. Forest land was used as a control. This study used descriptive explorative methods based on overlay land use, soil type, and industrial distribution map of Sragen Regency. The results showed that paddy soils with different management had higher Cd content than the forest soil. Organic paddy field had the lowest Cd content in soil (0.019 ppm) and rice grain (0.0006 ppm). Approximately 1,914.4 ha (3%) of paddy field in Sragen Regency that uses sugarcane industry wastewater as irrigation had the highest soil Cd content (0.16 ppm). In contrast, the highest Cd content in rice grain (0.046 ppm) was observed in conventional paddy field. The management of paddy field and rice cultivation significantly affected Cd contamination in soil and rice grain; therefore, environmentally friendly paddy field management needs to be encouraged.

Abstract

Due to the large amounts of freshwater consumed in Egypt by the agricultural sector that is more than 85% of Egypt share of freshwater in addition to the high concentrations of salts, chemicals and nutrients produced from fertilizers. Reduction of these pollutants concentrations to an acceptable level and breaking the sedimentation stability of colloidal substances and organic particles for reuse for irrigation purposes was associated with the application of biological treatment with coagulants addition. The flocculation process was performed by using polydiallyldimethylammonium chloride (polyDADMAC) and polyacrylamide grafted oatmeal (OAT-g-PAM). The scale-pilot consists of an aeration tank equipped with an air blower, sedimentation tank followed by a filtration stage through 20 cm of pottery scrubs media. To study the performance of synthetic and grafted polymeric flocculants, 3 trials were performed. Activated sludge process without adding any polymeric flocculants was the control trial. In the second trial, polyDADMAC was added with a dose of 5 mg/l. Finally, OAT-g-PAM with a dose of 1.25 mg/l was used in the third trial. The physicochemical properties of agricultural wastewater were measured at the national research center in Cairo. It was found that OAT-g-PAM incorporated with activated sludge process was the most effective in treating agricultural wastewater as it achieved COD, BOD,TKN, TP, and TSS removal efficiency up to 92.29%, 93.13%, 90.64%, 90.46%, and 92.5%, respectively which made it suitable to reuse for agricultural purposes, in addition to its ability to biodegrade, environmentally friendly, and low dosage required compared to polyDADMAC.

Abstract

This research was aimed to study the role of riparian trees and ecosystem degradation to determine water quality in some springs and its channels located in East Java. The research was held in some selected degraded springs in Kediri, Pasuruan, Malang, and the Meru Betiri National Park located in Jember, as a reference site. In each spring, three sites including upstream, midstream, and downstream were observed. The field observation consisted of several steps such as land use quality at river land side, geographical conditions, riparian tree diversity and water quality, quality of springs physical condition, and its channels. Riparian trees role to determine the water quality was analyzed by applying Partial Least Square analysis with Smart PLS software. Structural modelling of the interaction of riparian trees diversity with some determining variables of water quality revealed that there was an important role of riparian diversity quality towards water quality. The value of predictive relevance (Q2) was 99.11% and the model could be accepted. The riparian trees diversity and geographical conditions directly influenced the water colour and its turbidity. The quality of land use at several water bodies did not directly influence the water colour and its turbidity. Therefore, water colour and its transparency at channels were directly influenced by riparian width, ecosystem degradation shown by naturalness index, hemeroby index, environmental services index, and the slope of landside.
