Abstract

Eucalyptus urophylla plantation is an important contributor to carbon storage in climate change mitigation, established due to a land rehabilitation program in the semi-arid ecosystem in Timor Island. To ensure an accurate estimate of the above-ground carbon storage of these plantations, it is important to continuously combine ground measurement with remote sensing technology. Therefore, this study aimed to compare the above-ground carbon storage estimation of two very high spatial resolution images, namely Pleiades-1B 2021 and Pléiades Neo 2022 with pixel sizes of 2 x 2 m and 1.2 x 1.2 m, respectively. The normalized difference vegetation index was employed to identify the eucalyptus trees and classify the density into low, moderate, and high. The results showed that Pléiades Neo imagery provided superior eucalyptus tree identification to Pleiades-1B imagery and was more accurate in estimating above-ground carbon storage. However, there is a trade-off between increasing this accuracy and incurring a higher cost to achieve the highest spatial resolution image.

Abstract

The persistence of the carcinogenic Rhodamine B dye poses significant risks to human health. Utilizing a unique fungal strain for its degradation offers a sustainable solution to mitigate these hazards. Bioremediation techniques have demonstrated substantial promise in addressing recalcitrant pollutants such as dyes. In this particular study, laccase-producing fungi were carefully chosen for their potential to break down the toxic textile dye Rhodamine B. These selected fungi Cerrena unicolor FBR03 exhibited an impressive maximum degradation rate of 95.10%. Additionally, an analysis using GC-MS revealed the emergence of breakdown products, including 2-cyclopenten-1-one, 3-hydroxy-2-methyl, thymine, dodecanoic acid, tetradecanoic acid, n-hexadecanoic acid, and dibutyl phthalate. These results underscore the potential of this fungal strain as a promising organism for the effective degradation of dye compounds, while simultaneously producing valuable saturated fatty acids as by-products.

Abstract

Anthropogenic activities carried out by communities around forests in production forests, protected forests, and conservation forests have an impact on changes in the land cover of these areas. This impact is difficult to avoid because, on the other hand, production forests and protected forests are in direct contact with the lives of local communities. Changes in land cover have a significant impact on the contribution of Folu Net Sink, which is set by the government at 31.89% in 2030 with its efforts. This research aims to provide an overview of land cover changes that occurred in natural forests of the Eucalyptus urophylla type from 2002 to 2022. The method used in this research is a supervised/guided digital classification technique. Ground checks were also carried out in this research to match the accuracy of the image data with the actual conditions in the field. The research results show that changes in land cover in 2012 and 2017 were very extreme. Forest fires were the cause of changes in land cover during this period. Meanwhile, in 2002, 2007, and 2022, the land cover was still good, in a positive direction. The causes of changes in land cover are encroachment activities, encroachment, illegal logging, firewood theft, rice fields, forest fires, plantations, and farming. Forest preservation provides very high benefits for life on earth. Therefore, it is important to pay attention to the welfare of local communities so that they do not damage the forest, as well as increase the capacity to educate the community regarding zoning or blocks in conservation and protected forests. Apart from that, good forest management is needed to ensure forest sustainability in the future.

Abstract

The eruption of Mount Semeru at the end of 2021 was responsible for emitting volcanic ash with specific characteristics. These unique mineralogy and chemical properties have both positive and negative effects on soil fertility, as excessive heavy metals adversely affect soil, plants, and the environment. Therefore, this study aimed to determine the distribution of volcanic ash cover from the eruption of Mount Semeru and investigate elemental composition as well as mineral characteristics of volcanic ash and soil covered by volcanic ash. The investigation was carried out in Supiturang village, Pronojiwo District, Lumajang, East Java, Indonesia. Sampling was carried out following the toposequence method, covering agricultural land within approximately ± 15 km from Mount Semeru. Pure volcanic ash was collected at sites not contaminated with soil. At the site location, it was found that the depth of volcanic ash cover ranged from “thin” (<2 cm) to “very thick” (>10 cm). The results of SEM and XRD analyses showed that of the pure volcanic ash contained quartz (50%), rock fragments (15%), plagioclase (12%), hornblende (10%), opaque (8%), and pyroxene (5%) minerals. The results of XRF analysis showed that the dominant elements in volcanic ash and soil were silica (Si), aluminum (Al), calcium (Ca), iron (Fe), and potassium (K). Several non-essential heavy metal elements found were Pb, Sn, and As, while rare minerals discovered were Y, Nb, Eu, and Yb at relatively low concentrations. The SEM analysis showed the structure of volcanic ash dominated by prismatic and blocky.

Abstract

Reclaimed-mining soil (RMS) is characterized by low fertility, acidic pH, and high heavy metal contents. As a result, adding amendments becomes essential to support plant growth. Therefore, this research measured alterations in the characteristics of RMS, plant growth, and metal accumulation in plants with the co-application of coal fly ash (CFA) and empty fruit bunches of oil palm (EFBOP). In the first experiment, various levels of CFA (0, 75, and 150 Mg ha-1) and EFBOP (0, 25, and 50 Mg ha-1) were added to the RMS and then incubated at 70% water holding capacity for 45 days to determine their effect on changes in soil properties. In the second experiment, four treatments: control, CFA, EFBOP, and CFA+EFBOP were tested in the greenhouse to quantify their effects on the growth and metal accumulation of plants. Results of the study showed that the co-application of CFA and EFBOP significantly affected bulk density, pH, mineral nitrogen (NH4+ and NO3-), available phosphorus, and exchangeable Ca and Mg in RMS. CFA application increased exchangeable Al by 82-160%, while EFBOP resulted in a decrease of 24-119%. CEC decreased with CFA application and increased with the use of EFBOP. Plant growth increased with the co-application of CFA and EFBOP. The addition of CFA to soils results in increasing metal contents in plant tissue; however, the presence of EFBOP reduced the concentrations of metal in plant tissue. These results highlight the potential of CFA and EFBOP, which are industrial and agricultural wastes, as valuable soil amendments.

Abstract

This research aimed to determine the social, economic, and environmental impact of Saddang River sand mining on local communities and the Pinrang district government. Primary data collection used field surveys to obtain supporting data on economic aspects consisting of production capacity, costs, selling price of sand at the miner level and market price at the consumer level, number of grains, and various other economic values such as indirect value and indirect use value. The primary data collection method uses a total sampling of 80 miners operating in the research area. Consumer data uses a field survey method with 8 hours of observation per day. Saddang River sand mining provides great socio-economic value and environmental impact, directly or indirectly. This significant socio-economic value and impact, if not accompanied by good management, can result in over-exploitation, which impacts the physical and ecological damage of the Saddang River. On the other hand, the high rate of sedimentation from upstream of the Saddang River results in shallowing, so sand mining activities help normalize the Saddang River. Therefore, to continue providing economic benefits and the Saddang River to avoid physical and ecological damage due to mining activities, sustainable management of Saddang River sand mining is needed.

Abstract

Optimizing the potential utilization of low-rank coal, such as sub-bituminous coal (SC), can improve and maintain soil quality and productivity through amelioration technology. This potential is especially in controlling heavy metals such as Hg. This study aimed to examine the geochemistry of SC and the adsorption mechanism of Hg with SC through an adsorption isotherm model approach developed for experimental equilibrium. The geochemical of SC has an atomic composition of C (43.60%), O (40.64%), N (11.96%), Si (1.57%), Al (1.06%), Ca (0.92%), Mg (0.14%) and K (0.11%) and oxide composition dominated by SiO2 (57.07%), as well as O-H and N-H functional groups, C-H C-H, C=C-H, C=O, and C=C-H and minerals (quartz, magnetite, mica and muscovite). Characteristics of SC have a proximate composition (16.99% moisture, 97.81% volatile matter, 69.63% ash, and 28.19% fixed carbon) and chemical properties of pH, EC, CEC, OC, and total N (5.23, 1.38 dS m-1, 35.33 cmol(+) kg-1, 9.81% C,  and 0.16% N). The adsorption capacity and coefficient of Hg2+ by SC were 304.32 mg g-1 and 78.67 L kg-1 at pH 1.26 and Hg2+ concentration 100 mg L-1 with a removal efficiency of 76.08%. Hg2+ adsorption isotherms occurred in Langmuir (RL = 0.97 and R² = 1)>Freundlich (1/n = 1.05 and R² = 0.9999) models. The application of 40 t SC ha-1 on ex-gold mining soil contaminated with Hg significantly decreased the total Hg in the soil by 2.50 mg kg-1 and a removal efficiency of 36.37% with increased pH H2O (0.35), OC (0.041% C), and CEC 2.14 cmol(+) kg-1, compared to control.

Abstract

During the Industrial Revolution, agriculture was linked to environmental issues. One issue is pesticide pollution. Bioremediation is needed because plant diseases and pests cause farmers to use pesticides excessively, polluting and decreasing soil production. This study evaluated soil fertility from bioremediation with biduri plants, bacteria, and biochar on chlorpyrifos-polluted shallot-growing soil in Brebes Regency. This type of research was an experiment in a greenhouse, using a factorial experimental design with a completely randomized design, consisting of two factors, namely bioremediation agent (A0: without bioremediation agent, A1: Atlantibacter hermannii, A2: bacterial consortium) and coconut shell biochar (B0: without biochar, B1: with biochar). There were six treatment combinations, then replicated three times for each treatment, so there were 18 treatment units. The data were statistically analyzed using ANOVA, Duncan Multiple Range Test, and Pearson correlation. The results showed that the best treatments that were able to improve soil fertility after bioremediation were treatments A1B0 (Atlantibacter hermannii + without biochar), A2B0 (bacterial consortium + without biochar), and A2B1 (bacterial consortium + with biochar). The A1B0 treatment (Atlantibacter hermannii + without biochar) increased the pH by 4.97%, and the soil available P was 12 times higher than the initial soil. The A2B0 (bacterial consortium + without biochar) treatment increased soil cation exchange capacity by 99.81% and soil organic C by 116% higher than the initial soil. The A2B1 (bacterial consortium + with biochar) treatment increased soil total N by 37.50% and available K by 38.47%, higher than the initial soil.

Abstract

Forests serve as vital ecosystems, playing a pivotal role in preserving biodiversity, maintaining air and water quality, and regulating the climate, all while delivering many benefits to humanity and serving as a critical resource for diverse industries. This study investigated changes in forest cover within Yok Don National Park and surrounding areas in Dak Lak province, Vietnam, over the period from 2001 to 2021. The primary objective was to identify decadal shifts in forest cover through the utilization of freely accessible satellite remote sensing data and geographic information systems (GIS) tools. The maximum likelihood classification technique was employed to categorize Landsat images captured in 2001, 2011, and 2021. Furthermore, we evaluated the efficacy of the Normalized Difference Vegetation Index (NDVI) and the Soil-Adjusted Vegetation Index (SAVI) based classifications in detecting forest cover changes when compared to supervised classification. Initial estimates placed forest cover at 2796.91 km2, constituting 88.44% of the total land area in 2001, which subsequently declined to 2609.97 km2 (82.53%) in 2011, and further reduced to 1843.57 km2 (58.29%) in 2021. Severely reduced forest cover is often associated with the expansion of agriculture on the forest edge; other contributing factors include logging and illegal production land. Notably, the NDVI outperformed the SAVI in detecting forest cover changes. The findings of this research are anticipated to contribute to ongoing studies and enhance the effective monitoring of this protected forest area, thus providing invaluable insights for decision-makers.

Abstract

Optimized use of calcareous soil in dryland areas needs to begin with rehabilitation efforts using soil amendments, including organic fertilizer and biochar. This study sought to determine whether kinds of soil amendments and mycorrhizal biofertilizers may enhance the chemical quality of calcareous soils and increase the yield of sorghum on dry land. The study was conducted at the experimental garden of the Agricultural Extension Center located in Oelnasi Village from April to August of 2023. Two criteria included in the study were the kind of soil amendment and mycorrhizal biological fertilizer, both of which were arranged in a randomized block design. The parameters observed were soil chemical properties, plant N and P nutrient uptake, and sorghum yield. The research results showed that the application of three types of soil amendments (P1 = cow dung, P2 = rice straw compost, and P3 = corncob biochar) improved the chemical quality of calcareous soil. This application of corncob biochar could significantly reduce soil pH from 7.85 (slightly alkaline) to 7.19 (neutral) and increase soil organic C to 2.55% C, followed by treatment with cow dung and rice straw compost. Other soil chemical properties, i.e., N, P, K, and soil CEC, also improved, which differed from the control treatment. The mycorrhizal biofertilizer provided could also improve the chemical properties of calcareous soil. Providing mycorrhizal biofertilizer could increase the N and P nutrient uptake of sorghum plants by 3.79% dry weight-1 and 2.18% dry weight-1, respectively, as well as increased sorghum yields, respectively by 4.04 t ha-1, 3.97 t ha-1 and 3.87 t ha-1 dry beans, higher than the control which only achieved 2.32 t ha-1 dry beans.
