Invisible microplastics (MP) have become a significant problem worldwide in recent years. Although many studies have highlighted the sources, effects, and fate of MPs pollution on various ecosystems in developed countries, there is limited information on MPs in the marine ecosystem along the northeastern coast of the Bay of Bengal (BoB). Coastal ecosystems along the BoB coasts are critical to a biodiverse ecology that supports human survival and resource extraction. However, the multi-environmental hotspots, ecotoxicity effects, transport mechanisms, fates, and intervention measures to control MP pollution initiatives along the BoB coasts have received little attention. Therefore, this review aims to highlight the multi-environmental hotspots, ecotoxicity effects, sources, fates, and intervention measures of MP in the northeastern BoB to understand how MP spreads in the nearshore marine ecosystem. This study critically evaluates the hotspots and ecotoxic effects of pollution from MP on the coastal multi-environment, e.g., soil, sediment, salt, water, and fish, as well as current intervention measures and additional mitigation recommendations. This study identified the northeastern part of the BoB as a hotspot for MP. In addition, the transport mechanisms and fate of MP in different environmental compartments are highlighted, as are research gaps and potential future research areas. Research on the ecotoxic effects of MP on BoB marine ecosystems must be a top priority, given the increasing use of plastics and the presence of significant marine products worldwide. The knowledge gained from this study would inform decision-makers and stakeholders in a way that could reduce the impact of the legacy of micro- and nanoplastics in the area. This study also proposes structural and non-structural measures to mitigate the effects of MPs and promote sustainable management.

The coffee processing will produce a wastewater with a low pH. It is corrosive and dangerous for the environment. One of the alternative solution to solve this problem is by applying the coagulation-flocculation treatment. The natural coagulant that can be applied is the moringa seeds powder. The aim of this research is to optimize the coagulation – flocculation treatment by using mesh variation moringa seed powder in coffee wastewater pollution decreasing. Experimental design used a completely randomized design (CRD) to dosage the optimization based on mesh size variation in moringa seed powder with rind and rindless toward coffee wastewater pollution decreasing. Duncan assay showed that with α < 0.05, mesh size variation in moringa seed powder with rind and rindless was significantly different. The best treatment in coagulation – flocculation using moringa seed as nature coagulant was rindless moringa seed powder. The optimal particle size was 60 mesh due for having a little efficiency level with 70 mesh and 80 mesh and it is easier than the manual one. It has the efficiency level decreasing in TSS, turbidity and COD of 60 mesh was 69.44 ± 1%; 88.15 ± 0.5 % and 41.80 ± 0.5 %.

Rawa lebak lebung is a part of inland waters in South Sumatera which mostly used as the auction object, by granting a monopoly on fishing to Pengemin (auction winners). As an open-access resource, allowing a monopoly is considered to prevent conflicts of resource struggle and overuse. But in practice, the auction is precisely the cause of overexploitation, and the local community loses access to fishing. This study is intended to describe the suitability of Culture-Based Fisheries (CBF) implementation in the rawa lebak lebung in Ogan Komering Ilir (OKI) Regency based on practices under the auction regime, water quality, and aquatic biota communities. Increasing fish stocks and community involvement with CBF possible to develop with some adapted. This concept is carried out by spreading fish seeds to grow and harvest following fishing seasons, where local communities play an essential role. The analysis shows that the stock enhancement can be carried out in a limited way of the seed stocked. Poor swamp water quality requires the process of adaptation of seeds to be stocked. Community involvement is carried out by managing hatcheries, whose production is purchased by pengemin as an obligation to restore the environment.

Restoration of degraded drylands is urgently needed to mitigate climate change, reverse desertification and secure livelihoods for the two billion people who live in these areas. Bold global targets have been set for dryland restoration to restore millions of hectares of degraded land. These targets have been questioned as overly ambitious, but without a global evaluation of successes and failures it is impossible to gauge feasibility. Here we examine restoration seeding outcomes across 174 sites on six continents, encompassing 594,065 observations of 671 plant species. Our findings suggest reasons for optimism. Seeding had a positive impact on species presence: in almost a third of all treatments, 100% of species seeded were growing at first monitoring. However, dryland restoration is risky: 17% of projects failed, with no establishment of any seeded species, and consistent declines were found in seeded species as projects matured. Across projects, higher seeding rates and larger seed sizes resulted in a greater probability of recruitment, with further influences on species success including site aridity, taxonomic identity and species life form. Our findings suggest that investigations examining these predictive factors will yield more effective and informed restoration decision-making.

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 hydrophilicity of the membrane surface plays an essential role in improving membrane filtration performance. Better hydrophilicity could facilitate higher water permeation and prevent fouling phenomena. In this research, a green additive from ginger extract (GE) was employed to improve the polyethersulfone (PES) membrane hydrophilicity. The PES/GE membrane was fabricated via the phase inversion method by dispersing GE powder in PES/NMP solution using sonication followed by mechanical stirred. The influence of ginger extract (GE) on the PES membrane was characterized in terms of hydrophilicity, morphological structure, porosity, water permeation, chemical composition, and mechanical property. Water contact angle measurements showed that PES/GE membrane with 0.1% GE has the highest hydrophilicity. Scanning Electron Microscopy (SEM) indicated a porous finger-like structure on the cross-section membrane after the addition of GE.

Membrane separation technology has been extensively applied in separation processes. Improving membrane hydrophilicity plays a significant role in mitigating fouling phenomena and maintain membrane filtration performance. Fouling is a pore blockage of the membrane due to the interaction between hydrophobic molecules and membrane surface that cause membrane flux declining, shorter membranedurability, and increasing energy consumption. Incorporating inorganic particles to enhance membrane hydrophilicity is very attractive nowadays. Inorganic particles have unique characters due to their small size, excellent mechanical properties, and hydrophilic nature. This research aims to improve PES membrane filtration performances by employing nanocarbon and Fe2O3 as an inorganic additive. The membrane manufacturing process was carried out using a phaseinversionmethod., especially non-solvent induced phase separation (NIPS). The resulted membranes were analyzed by filtration soy protein solution to evaluate protein permeation flux and flux recovery ratio (FRR). The result experiments showed that PES/Nanocarbon could provide the highest FRR of up to 76.46%.
