This research investigates bacterial nanocellulose (BNC) composite reinforced with Titanium Dioxide (TiO2) in terms of morphology and membrane functional groups. Cetyltrimethylammonium Bromide (CTAB) was used as a surfactant. The purpose of this research is to investigate the effect of addition CTAB on the membrane composite. Bacterial cellulose (BC) pellicle was produced from the extract of pineapple peel waste. Acetobacter xylinum was used as the fermentation agent. The solution of 1% NaOH was applied for removing the BC pellicle impurities. Mechanical treatment and high pressure homogenize process had been done to synthesize BNC. The composite membranes were synthesized by using a mixture of BNC, TiO2 1%, and CTAB with different mass percentages, 0.5%, 1%, and 2%, and then the composite solution was dried by the oven for 14 hours at 80 °C. Properties of the composite membrane can be known based on its morphology and functional groups. Scanning Electron Microscope was used to observe the morphology. The results show that a higher concentration of CTAB makes BNC structure became more porous, and TiO2 particles spread more uniformly. FTIR analysis was conducted in range of 682cm-1, 862cm −1, 1041cm −1 and 3421 cm−1. Successively, they are the position of the C-OH, C-H, C-O-C, and O-H function clusters.

The dispersion of SARS-CoV-2 in aquatic environments via the discharge of domestic and hospital sewage has been confirmed in different locations. Thus, we aimed to evaluate the possible impacts of zebrafish (Danio rerio) exposure to SARS-CoV-2 peptide fragments (PSPD-2001, 2002, and 2003) alone and combined with a mix of emerging pollutants. Our data did not reveal the induction of behavioral, biometric, or mutagenic changes. But we noticed an organ-dependent biochemical response. While nitric oxide and malondialdehyde production in the brain, gills, and muscle did not differ between groups, superoxide dismutase activity was reduced in the "PSPD", "Mix", and "Mix+PSPD" groups. An increase in catalase activity and a reduction in DPPH radical scavenging activity were observed in the brains of animals exposed to the treatments. However, the "Mix+PSPD" group had a higher IBRv2 value, with NO levels (brain), the reduction of acetylcholinesterase activity (muscles), and the DPPH radical scavenging activity (brain and muscles), the most discriminant factors for this group. The principal component analysis (PCA) and hierarchical clustering analysis indicated a clear separation of the "Mix+PSPD" group from the others. Thus, we conclude that exposure to viral fragments, associated with the mix of pollutants, induced more significant toxicity in zebrafish adults than in others.

作者： Claudia Tyas Nugraheni Hidayat Pawitan Yanuar Jarwadi Purwanto Iwan Ridwansyah Postgraduate Program in Natural Resources and Environmental Management IPB Bogor Indonesia Department of Geophysics and Meteorology IPB Bogor Indonesia Department of Civil and Environmental Engineering IPB Bogor Indonesia Limnology Research Center LIPI Bogor Indonesia

Bogor Regency is one of Regencies in Jabodetabek area that is experiencing rapid urban growth. This condition impacted the decreasing conditions of 39's from 95's urban small lakes or locally known as 'situ'. This research aims to analyze the effectiveness of situ Kebantenan and situ Cikaret as Ciliwung flood mitigation measure in the Bogor Regency. The SWAT model was employed for quantification the water balance of situ and watershed management. The simulation results of the water balance analysis indicated that the monthly average of volume of Situ Kabantenan and Situ Cikaret (2008-2015) were 136,955 m3 and 508,907 m3, the annual inflow Situ Cikaret were 24,693,822 m3/year and outflow were 25,177,593 m3/year, precipitation were 648,520 m3/year, evaporation were 166,543 m3/year, delta storage (1,794) m3/year, respectively. The result of hydrological responses analysis on application of situ and watershed management scenarios that combined the structural and non-structural measures was the best scenario for decreasing maximum discharge at situ outlet which is decreased 41% discharge. So that, in order to enhance the effectiveness of situs for Ciliwung flood mitigation, the combination of the structural and non structural management of 13 situ's in Ciliwung river basin within the Bogor Regency is recommended that can increase the storage capacity from 1.8 million m3 to 4.7 million m3.

Despite the devastating effects of floods, the concept of resilience is still not fully considered in the assessment and management of flood risk. To study how resilience can lower the risk of floods and further enhance disaster response, this research aims to close this knowledge gap. With a focus on the Kashkan watershed in Iran, the study combines the extended catastrophe progression method with the pressure-state-response model. Three catastrophe models, namely the cusp, swallowtail, and butterfly, are applied. According to the findings, southern regions, i.e., Pol-Dokhtar city, have the highest risk of floods and the lowest resilience. Resilience and flood risk have a complementary relationship, according to the analysis, and resilience is a helpful metric for risk assessment. The results emphasize the necessity to incorporate resilience-focused pre-disruption planning and post-disaster recovery into flood risk management strategy. This work offers a foundation to incorporate resilience into future flood policies and strategies.

Crop residues hold promise to alleviate food vs. fuel competition and contribute to biofuel production. However, the impacts of lateral sediment and carbon fluxes caused by residue removal are not fully understood. Here we employ agroecosystem modeling to conservatively estimate lateral sediment and carbon fluxes resulting from partial corn stover removal in the U.S. Midwest. Results show substantial increases in soil erosion resulting from corn stover removal. For example, the area of continuous corn and corn soybean cropping systems exceeding soil erosion tolerance threshold could increase from 1.1 to 13.3% because of 66% corn stover removal. Depending on removal intensity, conservation, and crop rotation, the stover removal-induced increases in eroded soil organic carbon is equivalent to 3.9-12.5 gCOe MJ, which is comparable to other components of the life cycle impacts of corn stover-derived biofuel. Our findings highlight the need to consider the soil erosion and lateral carbon fluxes impacts of corn stover removal in designing supply chains for cellulosic biofuel production.

Efficiency of soil and water conservation practices in different agro-ecological environments in the Upper Blue Nile Basin of Ethiopia

In developing countries such as Ethiopia, research to develop and promote soil and water conservation practices rarely addressed regional diversity. Using a water-balance approach in this study, we used runoff plots from three sites, each representing a different agro-ecological environment, e.g., high, mid and low in both elevation and rainfall, in the Upper Blue Nile Basin of Ethiopia to examine the runoff response and runoff conservation efficiency of a range of different soil and water conservation measures and their impacts on soil moisture. The plots at each site represented common land use types（cultivated vs. non-agricultural land use types） and slopes（gentle and steep）. Seasonal runoff from control plots in the highlands ranged 214–560 versus 253–475 mm at midlands and 119–200 mm at lowlands. The three soil and water conservation techniques applied in cultivated land increased runoff conservation efficiency by 32% to 51%, depending on the site. At the moist subtropical site in a highland region, soil and water conservation increased soil moisture enough to potentially cause waterlogging, which was absent at the lowrainfall sites. Soil bunds combined with Vetiveria zizanioides grass in cultivated land and short trenches in grassland conserved the most runoff（51% and 55%, respectively）. Runoff responses showed high spatial variation within and between land use types, causing high variation in soil and water conservation efficiency. Our results highlight the need to understand the role of the agro-ecological environment in the success of soil and water conservation measures to control runoff and hydrological dynamics. This understanding will support policy development to promote the adoption of suitable techniques that can be tested at other locations with similar soil, climatic, and topographic conditions.
