Perencanaan Karir bagi Generasi Z dalam Pendidikan Islam
Authors: Syafrina Betri
Published: March 2022

Perencanan karier merupakan salah satu aspek penting dalam perkembangan karir individu. Namun generasi muda sekarang dalam mempersiapkan karirnya masih rendah dan bingung. Ada berbagai keresahan menunjukan bahwa kemampuan siswa, dimana dalam hal ini disebut sebagai generasi Z dalam mempersiapkan karirnya masih rendah, hal tersebut tampak dalam berbagai masalah baik yang berkaitan dengan pemilihan jenis studi lanjutan, pemilihan rencana pekerjaan, maupun yang berkaitan dengan ketidaksiapan para lulusan dalam memasuki pendidikan lanjutan atau dunia kerja. Hal ini dapat menjadi isyarat bagi dunia pendidikan untuk mengembangkan karir, baik dalam kegiatan intruksional maupun dalam kegiatan bimbingan dan konseling. Di samping itu, materi informasi yang bersifat personal, seperti bakat, ciri-ciri kepribadian atau minat pekerjaan perlu dikuasai oleh generasi Z. Generasi Z adalah digital natives, generasi yang sejak lahir telah terpapar oleh internet, jejaring sosial (social network), dan sistem seluler. Informasi karir dalam bimbingan karir islami diperlukan untuk pemberian bantuan terhadap individu agar dalam proses mencari pekerjaan dan bekerja senantiasa selaras dengan ketentuan dan petunjuk Allah, sehingga dapat mencapai kebahagiaan hidup di dunia dan akhirat. Bimbingan memiliki sifat preventif sehingga dalam proses pemberian bantuan lebih banyak menekankan agar seseorang dalam mencari atau mencapai suatu pekerjaan jangan sampai melanggar/menyimpang dari ketentuan dan petunjuk Allah swt.

Spatial analysis of major droughts in Seyhan River Basin, Turkey
Authors: Cavus Yonca , Stahl Kerstin , Aksoy Hafzullah
Published: March 2022

A particular location in a region may suffer from drought conditions while another may experience normal or even wet conditions. This study, therefore, performs spatial analysis using station-based monthly precipitation data for 19 meteorological stations over the Seyhan River basin in Turkey. Six major droughts each 2-year long at minimum were identified from the basin-average annual precipitation deficit. The Standardized Precipitation Index (SPI) was calculated for the meteorological stations at different time scales to characterize the severity and spatial extent of the major droughts. For the most severe month of each major drought, severities were interpolated over the river basin to form drought severity maps by using the Inverse Distance Weighted (IDW) technique. The study illustrates that the river basin experienced drought at least once every decade, which can be as severe as to impact the region and the whole country. Drought severity does not vary greatly over the river basin and it decreases with increasing accumulation time scales. The distribution of the most severe droughts changes depending on the characteristics of the major drought. We observed that the major drought in 1989-1990 was the most severe event in the time period. This is a significant statement for water resources planning with reference to the Seyhan River basin. Focusing only on the major droughts observed in the past when characterizing the severity of current drought events may improve our understanding of extreme meteorological drought events causing severe and long-lasting impacts.
Thunderstorm ground enhancements abruptly terminated by a Lightning flash
Authors: Chilingarian Ashot , Soghomonyan Suren
Published: March 2022

Thunderstorm ground enhancements (TGEs) registered on Aragats research station (530 events during  2008-2021) are frequently interrupted by the nearby lightning flashes. We are monitoring charged and neutral particle fluxes, near-surface electric field, distance to lightning flash, and numerous meteorological parameters 24/7. Our datasets [1,2] contains 165 TGEs interrupted mostly by the negative cloud-to-ground discharges (-CGs: 50%, inverted intracloud (IC) flashes followed by –CGs: 21%, inverted ICs: 18%, normal ICs:11%). The mean distance to the lightning flash estimated by EFM-100 electric mill is 5.8 +/- 3.1 km (based on 130 TGEs). Mean distance, estimated by a smaller subsample (18 TGEs) of this dataset, which contains also an estimate made by the worldwide lightning located network (WWLLN) is 6.6 +/- 5.6 km, by EFM – 4.5 +/- 2.6 km. The times of lightning occurrences measured by Aragats facilities and by the WWLLN coincide within a few microseconds. TGEs were interrupted by lightning during positive and negative near-surface electric fields. The TGEs which started at the negative (positive) near-surface electric field and terminated during the positive (negative) electric field were also observed.
An exceptionally record of microbial mats thriving in a volcanic caldera setting: The Ediacaran microbialites and mat-related structures of the Anti-Atlas, Morocco

The Anti-Atlas belt of Morocco preserves exceptional record of an Ediacaran microbial biosphere. The Amane Tazgart Formation of the Ouarzazate Group consist of an Ediacaran volcanic alkaline lake depositional system (ca. 571 Ma) were microbial buildups accreted in an extreme environment. These microbial accumulations are exceptional not only for their wide scope of extreme setting but also for their significance for understanding the early biosphere and earth habitability. A description of these buildups provides insights into their spatio-temporal distribution, in a 11 m-thick section. Specifically, the lower part consists mainly of thrombolitic limestone, usually displaying irregular to patchy mesoclots and occasionally arranged in dendritic pattern. The upper part dominated by clastic stromatolites, exhibit a variety of morphotypes ranging vertically from planar wrinkly laminated to large domes. The transitional morphotypes are made of linked and vertically oriented or inclined columns, grading upward to cone-shaped domes. The change from planar to columnar forms has been considered to indicate a shallowing trend, whereas the transition from columnar to domal morphotypes indicate a deepening trend. Spherulitic carbonate particles usually found within thrombolites, comprise radiating, wedge-shaped crystals. The analyses of spherulites-bearing samples using diluted acetic acids reveal the presence of microbial aggregates. They preserve spherical or globular shape and often irregular morphologies showing alignment along specific direction. Microfabric typical of Extra-polymeric substances (EPS) is preserved within these carbonate aggregates, suggesting their biological origin. The mineralogy of Amane Tazgart microbialites was studied using microscopical observation and XRD analyses. XRD show significant change in fabric composition from carbonate-dominated to clastic- and epicalstic-dominated microbialites, revealing the role of calcium carbonate saturation on microbialites genesis. Several features are preserved in the microbialites fabrics including micro-tufts and gas-bubbles and gas escape structure, forming evidence for mat growth and metabolic processes related to oxygenic photosynthesis and oxygen production.
Urban Moisture (Re)cycling: quantifying canopy effects using in-situ water stable isotope monitoring
Authors: Ring Ann-Marie , Tetzlaff Dörthe , Kleinschmit Birgit , Soulsby Chris
Published: March 2022

Urban green spaces are valuable infrastructure in the urban environment because they facilitate natural stormwater management through rainwater retention, decelerated runoff and enhanced evapotranspiration which can also mitigate heat stress. Investigating the complex interactions of water flux partitioning of incoming precipitation into “green” (i.e. evaporation and transpiration) and “blue” (surface runoff and groundwater recharge) water fluxes through urban vegetation is crucial to understand what types of landcover might best balance water re-distribution for a particular geographical setting and provide a cooling effect whilst not compromising groundwater recharge.

Stable water isotopes are very useful tools to investigate these complex processes. So far, studies investigating high-resolution ecohydrological process dynamics at the urban soil-plant-atmosphere interface, e.g. canopy evaporation, with stable isotopes are rare. Here, we conducted novel field experiments using direct in-situ monitoring of the isotope composition of evaporated atmospheric moisture at different heights above the soil surface, plant xylem and soil water in different types of urban greenspaces in Berlin, Germany. Results show a more homogenous spatio-temporal distribution of water vapour signals within the elevation profile of urban trees compared to grasslands, reflecting continuous interplay of interception evaporation, transpiration and soil evaporation. Additionally, grasslands showed a lower impact on the isotopic composition of atmospheric water vapor, mainly reflecting higher evaporative losses close to the ground surface. Complex patterns of precipitation fractionation under contrasting urban vegetation canopies were also revealed. Topsoil moisture rates strongly depended on the soil type and less on the above vegetation type.

The collected data on the redistribution of urban water in different types of green spaces is very helpful for the development of isotope aided ecohydrological models. This knowledge can further support valuable decision-making for sustainable urban development across scales.
The effect of SST anomalies on planetary waves dynamics: numerical experiments with ISCA
Authors: Sobaeva Daria , Zyulyaeva Yulia , Gulev Sergey
Published: March 2022

Stratospheric dynamics have predictive skills on a subseasonal timescale for troposphere synoptic processes, which plays a crucial role in the “seamless” forecasting approach. Therefore, predicting the state of the stratospheric polar vortex (SPV) is one of the top priority tasks for modern meteorology.

Early research showed that the intensity of the vertical propagation of wave 1 over Eastern Siberia could be a predictor for an extremely strong/weak SPV in the next month during the winter season. However, this connection does not always exist. During the negative phase of the Pacific Decadal Oscillation (PDO), 70% of the variability of the SPV intensity is explained by the dynamics of wave 1 in the previous month, and during the positive phase of the PDO, there is no statistically significant connection between them. It can be concluded that the nature of the spatial propagation of planetary waves differs in different phases of the PDO.

The work aimed to confirm the effect of large-scale SST anomalies on planetary waves propagation using numerical experiments with ISCA model and to prove results of observational analysis based on JRA-55 data that showed that wave 1 is more “stationary” during the negative PDO phases than during the positive ones. Distributions of the wave 1 ridges’ location for different PDO phases are significantly different at the 8% level according to Student’s t-test.

We analyzed the differences in the vertical components of the Plumb flux for isolated large-scale SST anomalies condition corresponding to the main modes of SST variability, such as PDO, El-Nino Southern Oscillation (ENSO), and for SST anomalies in the Kara-Barents Seas region. The experiments with combined conditions were carried out as well.
Numerical Advances in Understanding the Behavior of Gravity Retaining Wall during Seismic Motions
Authors: Singh Prerna , Bhartiya Priyanka , Chakraborty Tanusree , Basu Dipanjan
Published: March 2022

The response of gravity retaining walls during ground motion is still a challenging field. Recent developments in computational methods have opened the possibility of enhancing the understanding of the non-linear nature of soil-structure systems, e.g., earth pressure thrust acting on the retaining wall, translational and rotational movements, propagation of waves in the soil more realistically and quickly. Till today, Mononobe Okabe (MO) method (pseudo-static) is the most used analytical method because of its simplicity. However, there are many limitations and gives over-conservative results in terms of earth pressure thrust, and many literatures have already justified such a response. Several improved studies are already available, but very few have considered proper soil-structure interaction, real-time input earthquake data (not sinusoidal), and a sufficient number of earthquakes to evaluate the response acting on the wall during dynamic loading.

We seek contribution by analyzing the problem numerically using FE software Plaxis 2D and studying the behavior of retaining wall during seismic loading (range of amax = 0.053g to 1.2g) in terms of acceleration, displacement, rotation, and earth pressure thrust of retaining wall. The main contribution observed is the acceleration was not uniform throughout the medium instead gets amplified up to around 0.6g and later gets attenuated with maximum amplification occurring at the top of the retaining wall followed by the top of backfill soil and base of the wall. The residual displacement and rotation showed an incremental trend with an increase in horizontal seismic coefficient (kh). The earth pressure thrust obtained using numerical analysis was comparatively less than predicted by the MO method.

Published: March 2022

Dynamic topography is the surface expression of sub-plate mantle convective processes. In recent years, there has been considerable interest in combining a wide range of geophysical, geological and geomorphic observations with a view to determining the amplitude, wavelength and depth of mantle thermal anomalies. Here, we are interested in exploring how quantitative modelling of major, trace and rare earth elements can be used to constrain the depth and degree of asthenospheric melting for a mantle peridotitic source. Our focus is on a region that encompasses the Iberian Peninsula where previous research suggests that long-wavelength topography is supported by a significant sub-plate thermal anomaly which is manifest by reduced shear-wave velocities. Stratigraphic and fluvial studies imply that this dynamic support is a Neogene phenomenon. We analyzed 48 Neogene basaltic rocks that were acquired from Iberia in September 2019 and combined these analyses with previously published datasets. Both major element thermobarometry and rare earth element inverse modelling are used to determine the asthenospheric potential temperature and lithospheric thickness. These values are compared with those estimated from calibrated shear-wave tomographic models. Our geochemical results indicate that potential temperatures and lithospheric thicknesses are 1300-1375 °C and 50-80 km, respectively. These values broadly agree with calibrated tomographic models which yield values of 1300-1360 °C and 45-70 km. We conclude that a region encompassing Iberia is dynamically supported by a combination of warm asthenosphere and thinned lithosphere.

Soil texture is a key information in precision agriculture for improving soil knowledge and crop performances. A precise mapping of its variability is thereby imperative for rationally planning cultivations and targeting interventions. Unlike direct soil texture measurements that are punctual, destructive, and time-consuming, remote sensing surveys can give widespread, non-invasive, and fast indirect evidence of clay, silt, and sand content. In this study we investigate the performance of Airborne Gamma Ray Spectroscopy (AGRS) for discriminating different texture classes in the ternary diagram of soil texture.

The Mezzano valley (Ferrara, Italy), a 180 km2 rural area reclaimed in the last century, represents an extraordinary benchmark for validating our method. This area, for which a public soil texture map at 1:50000 scale and a spatial resolution of 500 m is available, was scanned by an AGRS system mounted on a dedicated aircraft. The aircraft flew over the study area in a grid-like path of ~500 m spacing, collecting 1469 geolocalized spectra. The K and Th punctual measurements were spatially interpolated by Ordinary Kriging to elaborate K and Th maps with the identical spatial resolution of the soil texture map. Simple and multiple linear correlations, as well as a non‑linear Machine Learning algorithm, were then performed between gamma and soil texture data.

The obtained results by a simple linear regression analysis highlight a moderate positive (negative) correlation between clay (sand) content and K and Th abundances. Multiple linear regressions show a similar trend, with the limitation that the calculated clay, silt, and sand values populate the soil texture ternary diagram in a straight line. Finally, we demonstrate that the most accurate reconstruction of soil texture values is obtained by a non-linear fitting based on the Machine Learning algorithm.
Does climate change affect mercury inflow to periglacial regions? (King George Island, Antarctica)

Published: March 2022

Mercury (Hg) is considered as a global pollutant. It is persistent in the environment and in organic compounds, mainly as methylmercury (MeHg), is accumulated in living organisms and it biomagnifies up the trophic chain. Periglacial areas in Antarctica have had the highest temperature rise in the southern hemisphere over the past fifty years (+3 ˚C). The loss of the ice cover and the exposure of larger and larger ground surfaces caused by the increasing temperature, enable the initiation of rock erosion and soil formation processes. The King George Island is formed by rocks of volcanic origin. Therefore, this material could be a source of many compounds in the Antarctic coastal zone. In turn, these new periglacicl areas are places where more life (flora and fauna) appears. Both of these factors disturb the circulation of many elements in the polar region. The aim of the study was to determine the impact of periglacial regions formation on the inflow of Hg to the Antarctic ecosystem. The bioavailability of Hg contained in rocks and soil in the study area was also tested.

Sampling took place in December 2018 and January 2019 in the King George Island. The samples of soil, lichen, moss, vascular plant and algae were collected and stored at -20 °C until analysis. The concentration of total mercury (THg) was measured by pyrolysis with the technique of atomic absorption spectroscopy on a direct mercury analyser DMA-80. To measure the concentration of methylmercury samples were extracted, MeHg concentration was measured using Automated Methtlmercury System MERX-M.

Research carried out on the King George Island has shown that mercury concentrations in soil and in rocks were slightly higher than those measured in continental Antarctica, but lower than in other parts of the world. However, concentrations of mercury in lichens were similar to those in urbanized regions worldwide. The research confirmed the correlation between the weathering processes of volcanic rocks in the studied area and the concentration of THg in the soil. Measured concentration of THg and MeHg in plants and lichens on King George Island indicated that bioavailable Hg was present in soil and rocks but weathering of rocks was only one of mercury sources. Methylmercury accounted for, on average, 15% of total mercury in lichens and plants samples but 0.1% in soil samples. The presence of animals - penguins and sea elephants had an impact on the increased concentration of THg and MeHg both in soil and in plant/lichen samples. 

This study has been performed within the framework of a National Science Center projects No. 2019/33/B/ST10/00290 and No. 2017/27/N/ST10/02230.
Dynamic vs. Hybrid Seasonal Rainfall Forecasts over Central America: A Comparative Evaluation of C3S and NMME
Authors: Kowal Katherine , Slater Louise J. , Van Loon Anne F.
Published: March 2022

Seasonal forecasts present an opportunity to enhance preparedness for hydrometeorological extremes in Central America. Many seasonal forecasts are publicly available, but their comparative value is not well understood, especially over the Central American region. Knowing how best to combine the different seasonal forecast models on offer, or when and where to trust them, requires further study. This evaluation compares seasonal rainfall forecasts over Central America with a focus on hydrometeorological extremes using two of the globally leading ensembles: the Copernicus Climate Change Service seasonal forecasting system (C3S), and the North American Multimodel Ensemble (NMME). We compare the two multimodel ensemble means, eleven individual model means, and model member predictions of monthly and seasonal rainfall over different months, locations, and lead times to better understand their relative forecast quality and identify potential regional predictability limits at the seasonal scale. Direct rainfall forecasts from the models are compared with indirect dynamical-statistical forecasts using large-scale climate precursors within a statistical rainfall prediction system. Results show that C3S and NMME exhibit similar regional variability in their direct rainfall forecasts, revealing the influence of important climate mechanisms on rainfall predictability in the region, which originate in both the Pacific and Atlantic Oceans. The models with the best skill also vary depending on the season, subregion, and lead time assessed. The relative accuracy of indirect versus direct forecasts is still under consideration but we expect their accuracy to vary geographically and seasonally, depending on the associations between the regional climate precursors (e.g. El Niño Southern Oscillation and Tropical North Atlantic variability) and local rainfall. Overall, the models compared can provide useful information on upcoming rainfall, but their regional and seasonal variability affect their usefulness for different types of forecasting applications.
