An edible film is a type of bioplastic packaging that can be used to package strawberries. Therefore, this study aimed to determine the packaging effect using nanobiocomposite edible film based on gelatin/nanocrystalline cellulose with the addition of antioxidants nanopropolis and storage temperature on the quality and shelf life of strawberries. The strawberries fruit were packed with edible film nanobiocomposite and stored at 5°C, 10°C, and 30°C. The parameters analyzed were water content, Vitamin C, hardness, total dissolved solids, pH, and shelf life. The results showed that the water content ranged from 23.95 to 65.89%w/b at the end of the storage period and was stable at 5°C and 10°C. Furthermore, hardness at the end of storage ranged from 0.265 to 0.431 kg/cm2 and all treatments experienced a decrease in Vitamin C content during storage. The total dissolved solids content at the end of storage was 5.92-12%Brix, with a shelf life ranging from 3-21 days of storage, as determined by all treatment parameters. These results showed that bionanocomposite edible film packaging can increase the shelf life of strawberries. © 2023, The Authors. All rights reserved.

Rural electrification using renewable energy is the best choice for many locations that far away from national grid. Many renewable energy project have been built for rural electrification such as micro hydro power plant (MHPP) and solar photovoltaic (SPV). Sustainability still the main challenge of off-grid renewable energy development for off-grid rural electrification in Indonesia. The objective of this paper is to review sustainability of micro hydro power development in Indonesia. The research method was done by field observation, interview with MHPP management, and reviewing some research about MHPP in Indonesia. Sustainability issues include various aspects that can be classified into 5 dimensions: technical, economic, socio-cultural, institutional, and environmental. In technical factors that lead to sustainability problem are: improper MHPP design and construction, improper operation and maintenance, availability of spare parts and expertise. In the economic dimension are generally related to: low electricity tariff and utilization of MHPP for productive use. In the social dimension are: the growth of consumer's load exceeding the capacity, reduced number of consumers, lack of external institutional support. In the institutional side, it is generally related to the ability of human resources in managing, operating and maintaining of MHPP. Environmental factors that lead the sustainability problems of MHPP are: scarcity of water discharge, conflict of water resources, land conversion over the watershed, and natural disasters.

For regulatory purposes, air pollution has been reduced to management of air quality control regions (AQCR), by inventorying pollution sources and identifying the receptors significantly affected. However, beyond being source-dependent, particulate matter can be physically and chemically altered by factors and elements of climate during transport, as they act as local environmental constraints, indirectly modulating the adverse effects of particles on the environment and human health. This case study, at an industrial site in a Brazilian coastal city – Joinville, combines different methodologies to integrate atmospheric dynamics in a strategic risk assessment approach whereby the influence of different wind regimes on environmental and health risks of exposure to PM2.5-bound components, are analysed. Although Joinville AQCR has been prone to stagnation/recirculation events, distinctly different horizontal wind circulation patterns indicate two airsheds within the region. The two sampling sites mirrored these two conditions and as a result we report different PM2.5 mass concentrations, chemical profiles, geo-accumulation, and ecological and human health risks. In addition, feedback mechanisms between the airsheds seem to aggravate the air quality and its effects even under good ventilation conditions. Recognizably, the risks associated with Co, Pb, Ni, Mn, and Zn loadings were extremely high for the environment as well as being the main contributors to elevated non-carcinogenic risks. Meanwhile, higher carcinogenic risks occurred during stagnation/recirculation conditions, with Cr as the major threat. These results highlight the importance of integrating local airshed characteristics into the risk assessment of PM2.5-bound components since they can aggravate air pollution leading to different risks at a granular scale. This new approach to risk assessment can be employed in any city's longer-term development plan since it provides public authorities with a strategic

The multichannel seismic survey consists of a geophysical technique of indirect quantification, whose principles are based on the acoustic properties of the seismic waves produced locally. The current study deals with seismic refraction, whose main advantages are avoidance of any environmental impact during the exploration, low cost and a fast way to present the results. The objective of the technique is to show acoustic characteristics of the geological environment, such as the propagation velocity of the P wave allowing the estimation of the type of rock that constitutes the subsoil. The layers depths determination depends on velocities estimated in the data analysis. The information provided by the seismic survey is used to determine the degree of vulnerability of local groundwater reserves. The region of interest of this study is the central depression of the State of Rio Grande do Sul, Brazil. This region consists of one of the recharge areas of the Guarani Aquifer System. This system consists of a set of geological formations rich in sand and poor in clay, which results in a kind of compartmentalized sponge with potential to accumulate groundwater, covered by impermeable rock. Profiles analyzed, in the region of the municipality of Santa Cruz do Sul suggest the presence of basalt, argillite and sandstone at approximately 10 meters depth. These conditions indicate a vulnerability of the aquifer which varies laterally. Therefore, some regions showed to be less protected than others, requiring more attention on the possibility of propagation of some contaminant.

The existence of extractive activities around the river has a negative impact on the quality of river water. This study aims to provide an overview of water quality characteristics and water quality status of Bengkulu River and Nelas River in Bengkulu Province. The data used is river quality monitoring conducted by the Environment and Forestry Service of Bengkulu Province from 2014 to 2019. Measurements are carried out twice a year representing, the dry season (March to June) and the rainy season (September to December). The observation stations representing upstream, middle and downstream of rivers conditions. The parameters observed were physical, chemical, and biological parameters. The water quality status is determined using the Storet Index. The results show that both rivers have Storet Index >-31. It means that these river water are heavily polluted. Parameters that have exceeded the water quality standard are TSS, DO, BOD, COD, Fe, Mn, Cu, and total coliform. The river water quality parameters, especially heavy metals, may be caused by open land being washed and carried into the river body. The existence of population and animal activities as well as industrial waste outlets at upstream also affect the decline of river water quality.

Understanding the sea surface wind structure during tropical cyclones (TCs) is the key for study of ocean response and parameterization of air-sea surface in numerical simulation. However, field observations are scarce. In 2019, three wave gliders were deployed in the South China Sea and the adjacent Western Pacific region, which acquired sea surface wind structure of eight TCs. Analysis of the field data suggests that the wave glider-observed surface winds are consistent with most analysis/reanalysis data (i.e., ERA5, Cross-Calibrated Multi-Platform, and National Centers for Environmental Prediction-Global Data Assimilation System) and Soil Moisture Active Passive. Both wave glider observations and analysis/reanalysis data indicate that TC wind fields induce an obvious increase in speed toward the sea surface together with a sharp change in direction, showing an asymmetric wind structure which is sensitive to TC translation speed and intensity. Larger mean values of wind speed and inflow angle are located on the right side along TC tracks. The inflow angle shows a highly dynamic dependence on the radial distance from the TC center, the TC intensity, as well as the TC-relative azimuth. Comparisons between field observations and theoretical models indicate that the most widely used, ideal TC wind profile models can largely represent the observed sea surface wind structure, but generally underestimate the wind speed due to lack of consideration of background wind. Moreover, simple ideal models (e.g., the modified Rankine vortex model) may outperform complex models when accurate information of TCs is limited. Wave glider observations have potential for better understanding of air-sea exchanges and for improvements of the corresponding parameterization schemes. © 2023. American Geophysical Union.

We aimed to evaluate the possible effects of the application of ZnO NPs (in the substrate, at 100 and 500 mg/kg) in the cultivation of Panicum maximum (Guinea grass), using biometric, morphological, biochemical, and productivity biomarkers in addition to evaluating the uptake of Zn by the plants. Furthermore, we assessed the possible transfer of ZnO NPs from P. maximum leaves to zebrafish and their effects on the health of the animals. Plants cultivated in substrates enriched with ZnO NPs at 500 mg/kg showed a lower germination rate and affected germination and plant growth. However, P. maximum grown on substrate enriched with ZnO NPs (at 100 mg/kg) showed higher biomass and productivity, associated with higher Zn uptake, without inducing redox imbalance and nitrosative stress. PCA analysis and cluster analysis confirmed the differential performance of the crop in substrate containing ZnO NPs at 100 mg/kg. Zinc content in zebrafish was not associated with ingesting leaves of P. maximum in substrate containing ZnCl2 or ZnO NPs or with genotoxic, mutagenic, and biochemical effects. In conclusion, ZnO NPs (at 100 mg/kg) are promising in the cultivation of P. maximum, and their ingestion by zebrafish did not cause significant ecotoxicological effects from the evaluated biomarkers. © 2023, The Authors.

Belawan Port is one of the main ports in Indonesia whose role and function are important in the national logistics system. Belawan Port is a gateway for the Province of North Sumatra. The port must have sustainability in carrying out its role and function as transportation and economic infrastructure. In this research, Belawan Port sustainability will be evaluated from several aspects or dimensions, namely ecology, economy, social culture, technology, and institutions and law. Belawan port sustainability analysis using the Multidimensional Scaling method, using the modified Rapfish program. The analysis is carried out on five dimensions and 49 attributes/factors, which are used as a reference in the SDGs program. Not every SDG will be relevant for every business, however, every SDG should be considered. SDGs no.4 and no.5 are not directly related to port management activities, while SDGs no.8,9,11,14,17 are directly related. From the analysis obtained Ecology sustainability index = 48.38 (less-sustainable), Economic sustainability index = 42.89 (Less-Sustainable), Socio-Cultural sustainability index = 52.47 (Fair-Sustainable), Technological sustainability index = 54.11 (Fair-Sustainable), Institutional and Legal sustainability index = 50.74 (Fair-Sustainable). With policy and program interventions, the sustainability of the existing Belawan Port in the short term can be improved to be fair-sustainable for all dimensions (ecology, economy, social & culture, Technology, Institution & Law) evaluated.

Pharmaceutical active compound (PhAC) residues are considered an emerging micropollutant that enters the aquatic environment and causes harmful ecotoxicity. The significant sources of PhACs in the environment include the pharmaceutical industry, hospital streams, and agricultural wastes (animal husbandry). Recent investigations demonstrated that wastewater treatment plants (WWTPs) are an important source of PhACs discharging ecosystems. Several commonly reported that PhACs are detected in a range level from ng L−1 to μg L−1 concentration in WWTP effluents. These compounds can have acute and chronic adverse impacts on natural wildlife, including flora and fauna. The approaches for PhAC removals in WWTPs include bioremediation, adsorption (e.g., biochar, chitosan, and graphene), and advanced oxidation processes (AOPs). Overall, adsorption and AOPs can effectively remove PhACs from wastewater aided by oxidizing radicals. Heterogeneous photocatalysis has also proved to be a sustainable solution. Bioremediation approaches such as membrane bioreactors (MBRs), constructed wetlands (CWs), and microalgal-based systems were applied to minimize pharmaceutical pollution. Noteworthy, applying MBRs has illustrated high removal efficiencies of up to 99%, promising prospective future. However, WWTPs should be combined with advanced solutions, e.g., AOPs/photodegradation, microalgae–bacteria consortia, etc., to treat and minimize their accumulation. More effective and novel technologies (e.g., new generation bioremediation) for PhAC degradation must be investigated and specially designed for a low-cost and full-scale. Investigating green and eco-friendly PhACs with advantages, e.g., low persistence, no bioaccumulation, less or non-toxicity, and environmentally friendly, is also necessary. © 2024 Elsevier Ltd
