This descriptive study analyzes PPh 21 calculation at the end of the year after TER implementation for WPOP permanent employees at PT. Anugrah. The analysis technique reduces PPh 21 calculation based on Pasal 17 rate with TER. The secondary data analyzed is PPh 21 calculation for 32 WPOP permanent employees. The research results show PPh 21 of 32 permanent employees at the end of the year is based on Pasal 17 rate of Rp. 50,909,825. The payable PPh 21 which has been deducted is IDR. 42,771,769, so there is a difference in taxes still to be paid in 2024 of Rp. 8,138,055. The application of TER is more profitable for low income taxpayers and large family status, while Pasal 17 rate tends to provide higher tax burden, especially for high incomes taxpayers and small family status. Government is expected to apply TER for a year's tax period, that it doesn't make difficult for tax payers by having to recalculate taxes at the end of the year. This creates inefficiencies in tax calculations. PPh 21 calculation payable with a TER is lower than Pasal 17 rate by reducing WPOP's tax burden.

Published: February 2025

Abstract. Launched aboard the Canadian SCISAT satellite in August 2003, the Measurement of Aerosol Extinction in the Stratosphere and Troposphere Retrieved by Occultation (MAESTRO) instrument has been measuring solar absorption spectra in the ultraviolet (UV) and visible part of the spectrum for more than 20 years. The UV-channel measurements from MAESTRO are used to retrieve profiles of ozone from the short-wavelength end of the Chappuis band (UV-ozone) and NO2, while measurements made in the visible part of the spectrum are used to retrieve a separate ozone (Vis-ozone) product. The latest ozone and NO2 profile products, version 4.5, have been released, and they initially cover the period from February 2004 to December 2023, although they will continue to be updated. The version 4.5 retrieval algorithm represents an improvement from previous versions, with changes including updated pressure and temperature input information, an improved algorithm for high-Sun reference spectrum calculation, improved Rayleigh scattering modelling, and the change to a Twomey–Tikhonov inversion algorithm from a Chahine relaxation technique. Due to the buildup of an unknown contaminant, the UV-ozone and NO2 products are only viable up to June 2009 for NO2 and December 2009 for UV-ozone. This study presents comparisons of the version 4.5 MAESTRO ozone and NO2 measurements with coincident (both spatially and temporally) measurements from an ensemble of 11 other satellite limb-viewing instruments. In the stratosphere, the Vis-ozone product was found to possess a small high bias, with stratosphere-averaged relative differences between 2.3 % and 8.2 %, although good agreement with the comparison datasets was found overall. A similar bias, albeit with slightly poorer agreement, is found for the UV-ozone product in the stratosphere, with the average stratospheric agreement between MAESTRO and the other datasets ranging from 2.8 % to 11.9 %. For NO2, general agreement with the comparison datasets is only found in the range from 20 to 40 km. Within this range, MAESTRO is found to have a low bias for NO2, and most of the datasets agree to within 27.2 %, although the average agreement ranges from 8.5 % to 43.4 %.
Analysis of Long-Term Changes in Extreme Waves in the Northwest Pacific Over the Past 60 Years
Authors: Fan Yang-Ming
Published: February 2025

Abstract. This study analyses wave height trends in the Northwest Pacific over the past 60 years and estimates design wave heights across various return periods to assess the resilience of marine and coastal structures to extreme wave events. Design wave height is a critical parameter for evaluating structural stability and safety, especially during typhoon season (May to October), when strong winds and rapid movements often trigger extreme waves, significantly impacting offshore structures, coastlines, and ports. To avoid underestimating risks during typhoon season, this study simulated wave heights from 1961 to 2020 using historical wind field data from the EC-Earth3 climate model and the WAVEWATCH III wave model. The 95th percentile was chosen as the threshold for extreme wave events, and the Generalized Pareto Distribution (GPD) model was applied for fitting. Finally, the bootstrap resampling method was used to quantify uncertainties in return periods to ensure reliable assessments of design wave heights. The analysis shows a slight increase in design wave heights with longer return periods (10 to 200 years) near Taiwan, with significantly higher wave heights observed in the southern and eastern regions, indicating a need to enhance disaster resilience in marine infrastructure designs for these areas.

Published: February 2025

Abstract. Groundwater-Dependent Ecosystems (GDEs) are widely distributed in arid and semi-arid regions and serve as critical ecological safety barriers. However, the precise identification and mapping of GDEs has long posed a challenge for researchers, as the integration of geospatial technologies and field measurement techniques has remained insufficient. This study selected the final year of a prolonged drought period and the current year for analysis. Key indicators, including vegetation cover (FVC), the difference between evapotranspiration and precipitation (ET-P), Terrain Wetness Index (TWI) and the vegetation groundwater uptake index (VGUI), were employed. The K-means clustering algorithm was applied for classification, and spatial overlay analysis was performed in the Urumqi River and Chai Wo-pu Basin in Xinjiang, China, to assess the spatial distribution and temporal variations of GDEs. Additionally, the results were validated through the integration of wetland distribution and field investigations. The findings indicate that areas classified as "likely" or "very likely" GDEs are predominantly concentrated around Dongdao Haizi, Chai Wo-pu Lake, salt lakes, and adjacent regions, covering 45.4 % of the potential rea. Over time, the area classified as "unlikely" and "highly unlikely" for GDEs shows an increasing trend. By introducing field data of the VGUI, the study eliminates the interference from factors such as human irrigation in the identification of GDEs in typical areas, achieving refined mapping. This work provides valuable insights for the precise identification of GDEs in arid and semi-arid regions.

Published: February 2025

Abstract. Saturation vapor pressure deficit (VPD), a measure of the difference between how much moisture the atmosphere can hold versus how much is present, is highly correlated with the annual mean area burned by wildland fires in the western United States. The present analysis uses linear inverse models (LIMs) to forecast seasonal VPD and decompose skill into contributions from a nonlinear trend, coupled sea surface temperature (SST)-VPD variability, and VPD-only variability. Subregions of the western US are considered using Geographic Area Coordination Centers which have different times of year and lead times for which VPD forecast skill is greatest. However, the sources of skill are similar among the subregions. In LIM forecasts, particularly those made for summer and early fall, the trend contributes to VPD skill up to 18 months in advance, with a secondary contribution from internal VPD variability at lead times of one to two months. Positive SST and VPD anomalies and negative soil moisture anomalies are associated with the positive sign of the trend time series, which has been observed without interruption since the late 1990s. Coupled SST-VPD variability contributes to VPD skill mainly for forecasts verifying between December to May for lead times up to 12 months in some subregions. Forecasts that are especially skillful and display high confidence, seasonal forecasts of opportunity (SFOs), are associated with SSTs that produce high VPD skill over California, the Southwest, and Texas, while internal VPD anomalies contribute to skill over the Great Basin and western Northern Plains. SFOs are initialized during periods of El Niño-Southern Oscillation development, with La Niña SSTs associated with positive western US VPD anomalies and consequently, enhanced wildland fire risk.

Abstract. Because of the computational costs of computing storm surges with hydrodynamic models, projections of changes in extreme storm surges are often based on small ensembles of climate model simulations. This may be resolved by using data-driven storm-surge models instead, which are computationally much cheaper to apply than hydrodynamic models. However, the potential performance of data-driven models at predicting extreme storm surges is unclear because previous studies did not train their models to specifically predict the extremes, which are underrepresented in observations. Here, we investigate the performance of neural networks at predicting extreme storm surges at 9 tide-gauge stations in Europe when trained with a cost-sensitive learning approach based on the density of the observed storm surges. We find that density-based weighting improves both the error and timing of predictions of exceedances of the 99th percentile made with Long-Short-Term-Memory (LSTM) models, with the optimal degree of weighting depending on the location. At most locations, the performance of the neural networks also improves by exploiting spatiotemporal patterns in the input data with a convolutional LSTM (ConvLSTM) layer. The neural networks generally outperform an existing multi-linear regression model, and at the majority of locations, the performance of especially the ConvLSTM models approximates that of the hydrodynamic Global Tide and Surge Model. While the neural networks still predominantly underestimate the highest extreme storm surges, we conclude that addressing the imbalance in the training data through density-based weighting helps to improve the performance of neural networks at predicting the extremes and forms a step forward towards their use for climate projections.
Groundwater recharge in Brandenburg is declining – but why?
Authors: Francke Till , Heistermann Maik
Published: February 2025

Abstract. Brandenburg is among the driest federal states in Germany, featuring low rates of ground water recharge (GWR) across large parts of the state. This GWR is fundamental to both water supply and the support of natural ecosystems. There is strong observational evidence, however, that GWR has been declining since 1980: first, river discharge (which is almost exclusively fed via GWR) has been significantly decreasing in many catchments (by around 40 % since 1980). Second, ground water levels in the groundwater recharge areas show a significant long-term decline. In this study, we search for potential reasons behind this decline, by investigating five catchments across Brandenburg that we consider as largely unaffected by direct anthropogenic interference with the water balance. Using the Soil-Water-Atmosphere-Plant model (SWAP) to simulate long-term trends in GWR, we found that significant increases of air temperature, solar irradiation and leaf area index (LAI) since 1980 acted towards a decrease in GWR in the order of -21 to -4 mm a-1 per decade from 1980 to 2023. The Brandenburg-wide LAI trend of +0.1 m2 m-2 per decade was inferred from a recently published, spatio-temporally consistent LAI reconstruction. The contribution of this LAI trend to the decrease of GWR amounted to -5 to -3 mm a-1 per decade. Based on our results, we consider it as very likely that the decrease in discharge since 1980 can be explained by a decrease in GWR which, in turn, was caused by climate change in combination with an increasing LAI. However, we also found that precipitation trends can be highly incoherent at the catchment scale. Even though these precipitation trends are not significant, they can have a fundamental impact on the significance, the magnitude and even on the sign of simulated GWR trends. Given the uncertainty of the precipitation trend, four out of five catchments still appear to exhibit a gap between negative simulated GWR trends and more negative observed discharge trends. We provide a comprehensive discussion of possible reasons and uncertainties to explain this gap, including the effects of the limited length and the inhomogeneity of climate and discharge records, the role of land cover and vegetation change, irrigation water consumption, latent anthropogenic interventions in the catchments water balance, uncertainties in ground water table depth, as well as model-related uncertainties. Addressing these uncertainties should be a prime subject for prospective research with regard to the effects of environmental change on GWR in Brandenburg. Water resources management and planning in Brandenburg should, however, already take into account the possibility of GWR to decrease further. Given the fundamental importance of precipitation trends and their large uncertainty in future projections, we strongly advise against putting our hopes in a future increase of GWR as projected mainly on the basis of expected future increases in winter precipitation.

Abstract. This study investigated 48 current-use pesticides (CUPs) and 30 organochlorine pesticides (OCPs) in ambient air at a rural-agricultural site in the Czech Republic, with biweekly sampling over three and 10 years, respectively. Despite being banned decades ago, OCPs persist in the atmosphere, with revolatilisation from soils apparent in summer. Temporal trend analysis revealed decreasing atmospheric concentrations for several OCPs, which indicate diminishing reservoirs in environmental compartments especially soil over the years. For β- and γ-HCH, o,p’- and p,p’-DDE, o,p’-DDD, o,p’- and p,p’-DDT, α-chlordane, and mirex levelling off is observed, which points to recently enhanced secondary sources in the region or beyond i.e., reversal of the direction of air-surface exchange or recent mobilisation from soils, water bodies, or the cryosphere. CUP concentrations peaked during application seasons, with multi-annual trends either insignificant or declining. For compounds like chlorpyrifos and fenpropimorph, declining trends aligned with regulatory bans, though their presence in the atmosphere was evident one-year post-ban, suggesting persistence.

Authors: Anggreni Monica , Ariefka Reza
Published: February 2025

In Indonesia, according to the 2022 PISA results, students' scientific literacy is in a low category, equivalent to the results obtained in 2006, and is ranked 68th out of 81 countries. Based on existing problems, innovation is needed to increase scientific literacy, one of which is using science teaching aids. This research examines the effect of using urine formation teaching aids on the scientific literacy abilities of grade IV students at SDN 2 Riang Bandung. In this research, the method used is a quantitative method in which the research experiments with a one-group pretest-posttest design, and the data collection techniques are in the form of observation, tests, and documentation. The data processing technique was obtained through test instrument testing and hypothesis testing. From processing this data, the normality test value was obtained, which had a pretest value of 0.171, then the post-test value was 0.051, which stated that the value was normal. Then the homogeneity test which has a pretest value of 0.075 which is explained that the value is greater than 0.05 which is stated that the value is homogeneous. Finally, the paired sample t-test has a pretest value of 0.000, which means the value is smaller than 0.05.

Biomaterials possess electrical, optical, and magnetic
properties, which make them promising candidates for
targeted drug delivery. Moreover, their biocompatibility and
low toxicity render them suitable for applications in tumor
therapy. We conducted a bibliometric review to investigate
trends in biomaterials for bone tumor therapy. Relevant
studies published between 2013 and 2024 were identified
using the Web of Science database. The Bibliometric R-package
and CiteSpace software were used to quantitatively analyze
the number of papers, countries, authors, institutions,
sources, co-cited literature, and keywords. Papers were
categorized according to the main research subject, and
those cited at least 10 times annually were qualitatively
analyzed. Over the last decade, the number of papers and
mean annual citation rate increased. Most papers originated
from the USA and China, and the institutions with the highest
contributions were the University of California and Harvard
University. Among authors, Zhang had the highest number
of published articles and maximum citations according to
the H-index. The International Journal of Radiation Oncology,
Biology, Physics had the highest number of publications.
Keyword analysis revealed a focus shift from cells, receptors,
and gene therapy to immunological therapy, photothermal
therapy, and drugs. Notably, recent research has mainly
considered external and internal microenvironmental stimuliresponse strategies. This review offers a valuable basis for
developing intelligent and versatile biomaterials for bone
tumor therapy and regeneration in future investigations.

Introduction: Deep medullary vein thrombosis (DMVT) is a
rare but significant cause of neonatal stroke, characterized
by venous congestion and thrombosis in subcortical white
matter. Early identification is crucial due to its association
with long-term neurological sequelae.
Case Description: We report the case of a term neonate
presenting with focal seizures at 48 hours of life. Prenatal
history was significant for fetal growth restriction and
vacuum-assisted delivery. Neuroimaging revealed radial,
fan-shaped T2 hypointense lesions in periventricular
white matter as hallmark findings of DMVT. Compound
heterozygosity for MTHFR mutations was identified. Seizure
management with phenobarbital and supportive care were
prioritized, with serial imaging showing favorable evolution.
At 12 months, the child exhibited an unremarkable neurologic
examination and appropriate psychomotor development
without recurrent seizures.
Discussion/Conclusion: This case highlights the importance
of early neuroimaging in neonates with seizures or atypical
neurological presentations. Enhanced awareness and
understanding of DMVT among clinicians may reduce
diagnostic delays, ultimately improving outcomes. The
absence of standardized treatment protocols underscores
the need for further research.

Authors:   Master Student-Chemical Engineering Department- Sharif University of Technology, Tehran, Iran., Delashoob Abolfazl
Published: February 2025

This study investigates the efficacy of a modified Upflow
Sludge Blanket Filtration (USBF) system in the biological
removal of nitrogen and phosphorus from saline wastewater
generated by refineries. In this research, the experimental
design was conducted utilizing two retention times of 12 and
24 hours, two nitrogen concentrations of 200 and 400 mg/l,
a single phosphorus concentration of 20 mg/l, three levels
of Chemical Oxygen Demand (COD) at 800, 1000, and 1200
mg/l, and three salt concentrations of 10, 12, and 20 g/l.
The findings reveal that the Chemical Oxygen Demand (COD)
removal rate is exceptionally high, ranging from 89.4% to
98.9%. Furthermore, an increase in the nitrification rate
correlates with a rise in the quantity of nitrate entering the
anaerobic reactor, where the nitrate removal rate fluctuates
between 47.9% and 82.8%. The percentage of phosphorus
removal is observed to be between 81.7% and 96.1%. These
results underscore the effectiveness of the modified Upflow
Sludge Blanket Filtration (USBF) system in the treatment
of industrial saline wastewater. The system’s capability to
concurrently eliminate organic pollutants, nitrogen, and
phosphorus positions it as a viable solution for the treatment
of complex refinery effluents.
