COMPARATIVE ANALYSIS OF WIND PRESSURE OF UNTAR MAIN BUILDING
Authors: Vincent  , Leman Sunarjo 
Published: April 2024

Wind flows from high to low pressure due to presence of solar heat. The movement of wind in air is freely
exposed to obstacles such as buildings, especially in large cities. Buildings that are exposed to wind create
pressure for building which can be compressive or suction. In this study, wind pressure analysis was used in
three ways, that is with MIDAS GEN software, Autodesk CFD, and with manual calculation analysis
referring to Indonesia National Standard (SNI) 1727:2020. The building modeling used as test is main
building of UNTAR campus 1 with total height 89 m. The tested wind direction moved from south to north
and from west to east at a wind speed 32 m/s. The results of analysis showed that percentage of wind
pressure results between MIDAS GEN with manuals was at least 5.66% for both wind directions and
between CFD and manuals at least 0.7% for wind directions from south to north. The results from CFD also
show that result the main building surface wind pressure for wind flows moving from south to north results in
wind load in the edge area building smaller than in the central area building. The amount of wind pressure in
center of surface can be 4 to 5 times greater than wind pressure at the edge of surface.

Published: April 2024

Aim. To develop optimized conditions for isolating the new antidepressant paroxetine from model blood and urine samples by the liquid extraction followed by the determination of the analyte using the UV spectrophotometric method.
Materials and methods. The studies were performed with model samples of the donor blood and urine spiked with paroxetine. In the sample preparation of blood, the form elements were previously precipitated by 10 % solution of trichloroacetic acid. Endogenous impurities were removed by the extraction purification with chloroform from an acidic medium at pH 1, and paroxetine was extracted from the biological fluids under study with ethyl acetate at pH 10. The organic extracts obtained were further purified using the TLC method. After that, the determination of paroxetine in the eluates obtained from chromatograms was performed using the UV spectrophotometric method.
Results and discussion. The Rf value of paroxetine in the mobile phase of ethyl acetate-methanol-25 % ammonium hydroxide solution (85:15:10) was 0.42 ± 0.02. The UV spectra of eluates from chromatograms had absorption maxima at wavelengths of 265 ± 2, 272 ± 2 and 293 ± 2 nm and matched with the UV spectrum of a standard solution of paroxetine in 0.1 M solution of hydrochloric acid. The quantitative determination was performed at λmax293 nm according to the equation of the calibration curve y=0.0094x–0.02. The methods developed allowed to isolate 70.0 ± 4.0 % of paroxetine from the urine, 26.0 ± 3.0 % from the blood plasma and additionally 5.4 ± 0.6 % of the antidepressant studied from the blood cell sediment after its preliminary separation from the blood plasma.
Conclusions. The optimized conditions for sample preparation of model blood and urine samples by the liquid extraction method in relation to paroxetine have been determined. The results obtained are of applied practical significance for creating an algorithm in the toxicological study of biological fluids for the presence of this antidepressant in fatal drug intoxications.

Published: April 2024

Anxiety-depressive disorders are among the most common mental health conditions and often cause significant functional impairment, affecting a person’s quality of life. Research conducted in recent years indicate the importance of studying and searching for new substances based on benzodiazepines, in particular triazolobenzodiazepines, for the treatment of anxiety states and disorders, as well as determining the presence of other biological activities of these compounds.
Aim. To study the antidepressant activity of new derivatives of 1,2,3-triazolo-1,4-benzodiazepines in the Porsolt forced swim and tail suspension tests.
Materials and methods. The antidepressant activity of new 1,2,3-triazolo-1,4-benzodiazepine derivatives under the code MA-252, MA-253, MA-254, MA-255 and MA-261 was studied in the Porsolt forced swim and tail suspension tests. The following behavioral reactions, such as the latent period of the first immobility (more than 5 seconds), the total duration of immobility (staying in a stationary state), the number of immobile episodes, were recorded.
Results and discussion. During the study, a decrease in the total duration of immobility, the main indicator of “despair” of animals, and an increase in the latent period of the first immobility were monitored. It may indicate the manifestation of antidepressant properties of new 1,2,3-triazolo-1,4-benzodiazepine derivatives. The indicator of the antidepressant activity in groups of animals administered MA-253, MA-254 and MA-255 derivatives in all doses was higher among the groups studied. The depression index was the lowest when MA-253 and MA-254 derivatives were used in the dose of 1 mg/kg, and was not statistically significantly different from that in the group receiving imipramine in the dose of 25 mg/kg. According to the results of the tail suspension test, 1,2,3-triazolo-1,4-benzodiazepine derivatives MA-253, MA-254 and MA-255 showed a significant decrease in the total duration of immobilization by 69.4 %, 47.1 % and 33.1 %, respectively, in relation to the control group (p<0.05), as well as an increase in the latent period of the onset of the first immobility episode by several times.
Conclusions. A decrease in the duration of immobility in mice injected with 1,2,3-triazolo-1,4-benzodiazepine derivatives gives grounds to draw a conclusion that animals develop a state of “behavioral despair” and exhibit antidepressant properties.

Authors: Murtadho Muhammad Ali Arif , Eryansyah Eryansyah , Silvhiany Sary 
Published: April 2024

English textbooks are a valuable tool for promoting the development of 21st century skills. Meanwhile, multimodal texts in textbooks are employed by authors to convey meaning through verbal and visual modes, thus necessitating the adoption of multimodal analysis as the most efficacious method for its elucidation. Regrettably, there exists a dearth of literature concerning the application of this approach for analyzing textbooks. To fill this gap, the study examined 21st century skills in an English textbook. This study used content analysis with multimodal social semiotic approach. The subject of the study was an English textbook “English for Nusantara” for the seventh-grade students. The result shown that critical thinking and problem-solving skill was the most frequent type. However, the study did not find any mention of media literacy, and there were only a few instances of economic literacy and global awareness. It is suggested that future revisions should include them. Moreover, English teachers are urged to actively participate in the process of textbook selection and augment the instructional materials with supplementary resources to mitigate any inadequacies of the textbook.
