Hence, this study analyzed the average duration for Civil Engineering journals based on the points allocations in Poland's Ministry of Science and Higher Education (MEiN) list. A total of 30 journals were randomly selected and grouped based on the regional points allocation. The date of submission to the date of acceptance (SA) and the date of acceptance to the date of publication (SP) were extracted from 3557 articles. Version 26 IBM Statistical Packages for Social Sciences (SPSS) was used to analyze the average duration for the dataset. Multivariate Analysis of Variance (MANOVA) was used for the analysis of the relationship between the points allocation and the Scopus impact factors (IF), Web of Science impact factors (WoS IF), source normalized impact per paper (SNIP), SA, and SP. The results show that the average duration SA and SP for journals with 200, 140, and 100 points within the 5 years are 305.28, 285.25, 317.93 days, respectively, while for journals with 70, 40, and 20 points, the average duration is 180.50, 324.60, 206.41 days. Further analysis shows a statistically significant difference between the Scopus IF, WoS IF, SNIP, and allocated points. They indicate that these journal metrics affect journal categorization.

Involving the self-gravitation effect of the emitted particles, energy and angular momentum has been taken as conserved and considered the space time background as dynamical. The explored results shown that the massive particle tunneling rate is related to the change of Bekenstein-Hawking entropy and the derived emission spectrum deviates from the pure thermal spectrum.

Amidst the challenge of growing antimicrobial resistance, incorporating these nanoparticles into drug delivery systems could offer solutions. Thus, their extensive production holds promise, particularly in healthcare. This experimental research aimed to unveil the potential of Betel leaf (Piper betel) extracts to formulate Silver Nanoparticles and their antibacterial, antioxidant, and cytotoxic properties. UV-VIS Spectrophotometry was utilized to quantify the bioformulated AgNPs. The presence of biosynthesized silver nanoparticles was verified by the color change in all five varying concentrations of solution from greenish to dark brown. The decrease in bacterial growth rate becomes noticeable as the concentration of Ag nanoparticles rises. AgNPs in Sample 5 (higher concentration) exhibited the highest antibacterial activity for Staphylococcus aureus (11.25 mm and Escherichia coli (11.20 mm)-both partially active. The lowest activity was observed in Sample 1(lowest concentration) for both S. aureus and E. coli (10.16 mm). The result of the study shows that at 1000 ppm for the first three hours, no shrimps died. On the other hand, in the succeeding hours, the mortality rate increases. The study revealed that silver nanoparticles can be synthesized in a simple method using betel leaf extract. It is a straightforward, effective, and environmentally friendly process.

This can also be seen in the company's and its employees' relationships. Engaged employees usually have high loyalty to the company. This study aims to determine the influence of reward and recognition on employee engagement. This study uses a descriptive technique with a quantitative approach. The population studied is Directorate H at PT. X by specializing in employees who have worked for one year or more. Sampling with probability sampling technique to get a sample of 176 people. Data was collected by distributing questionnaires and then processed through Partial Least Square-Structural Equation Modeling (PLS-SEM) analysis using the SmartPLS application. Based on the research results, reward has a positive and significant effect on employee engagement, and recognition also has a positive and significant effect on employee engagement. From these results, the company can maintain a sound reward system and increase recognition by recognizing small things around the company so that employees feel more valued.

Information technology-based learning (e-learning) is learning where all information is centered on students. If the educator is not present, learning can still be done with e-learning learning which can be accessed using the internet. Current learning at ITB STIKOM Bali, especially in the Information Systems course, is still not effective due to limited learning resources that can increase student enthusiasm for learning. This lack of learning resources for students is a problem during a pandemic and currently facing the digital era due to unpreparedness in dealing with the digital world, this also occurs at the ITB STIKOM Bali campus which still uses learning resources that are less attractive and less interactive which causes students to be less interested to learn. This is supported by data from questionnaire results from 60 students who have completed GIS lectures with previous learning resources, around 72% of students stated that they agreed with the development of learning resources using multimedia e-modules. This course was chosen in the development of teaching materials because teaching Geographic Information Systems requires high-level thinking skills in the process of understanding theory and its applications, therefore higher-order thinking skills play an important role in developing understanding of the material and learning along with it. requires high concentration in digital map digitization. Based on these problems, it is necessary to develop learning resources in the form of Moodle-based multimedia-based e-modules that can be accessed by students online. The method of making an application using the method. The research method consists of literature study, MDLC (Multimedia Development Life Cycle) stages and evaluation. Testing the e-module by giving questionnaires to students taking Geographic Information Systems courses. The software used in making e-modules is Adobe Captivate and other supporting software in photo, audio, and video editing. Testing the effectiveness of the e-module by giving pre-test and post-test to 20 students randomly with an average N-Gain learning result of 0.78 in the high category so the e-module is very effectively used as a learning resource.

It was recognized that financial knowledge is crucial in daily life and the business world. However, the need for a renewal in the teaching of financial mathematics has been raised due to the global financial crisis. The complexity of mathematical models in finance was highlighted, and the importance of higher-order thinking skills in this field was underlined. In addition, the dependence of financial mathematics on disciplines such as statistics and computer science is evident, and exploring areas such as psychology and neuroscience was suggested to obtain a better understanding of the complex aspects of finance. In summary, this article emphasizes the intimate relationship between mathematics and finance. It highlights the opportunities for development and the need for a multidisciplinary perspective in mathematical finance.
