Published: October 2022

The purpose of the work is to analyze the technical, methodical and psychological aspects of digitalization in education and, in particular, the methods of ensuring the effectiveness of independent work of students in the conditions of e-learning. The main attention is paid to the problem of the influence of interactive educational technologies on the formation of external and internal motivation of students of economic specialties to study mathematical disciplines.
Methodology. In the conditions of e-learning continuous monitoring of the success of students in mastering mathematical methods and their application to solve economic problems was carried out. The success of each student in performing each type of work separately, as well as his overall rating among other students in the group, were determined. These results were supplemented by the results of the students' questionnaire regarding their own attitude towards interactive technologies as a tool aimed at forming motivation for learning.
Results. The virtual environment for e-learning was built using Moodle LMS and contained learning digital resources of various levels of interactivity, including electronic multimedia publications. This helped to fully meet the needs of the distance educational process. To form the student's external motivation, the authors used an electronic journal in which the types of current tasks, points for their completion, the student's rating for each type of tasks, as well as for all types of tasks in general, are defined. To support internal motivation, interactive learning elements were developed and implemented. The effectiveness of the use of digital resources was confirmed during the monitoring of students' success and by the results of the survey of the participants of the experiment.
Conclusions. A significant advantage of the use of interactive components in the educational process should be considered the creation of conditions for a better understanding of theoretical material and using mathematical apparatus for solving real economic problems. The use of multi-level digital resources gives the student the opportunity to build an individual educational environment that increases internal motivation to study.

Stuck Pipe Detection For North Sumatera Geothermal Drilling Operation Using Artificial Neural Network
Authors: Sarwono Sarwono , Lukas Lukas , Kartawidjaja Maria Angela , Wardana Raka Sudira 
Published: October 2022

One of the most common problems encountered during geothermal drilling operations is stuck pipe. The risk of stuck pipe is higher in geothermal drilling operations since geothermal drilling targets the lost circulation zone at reservoir depth. The stuck pipe problem can cause a significant increase in drilling time and costs. The cost of a stuck pipe includes the time and money spent on extracting the pipe, fishing the parted BHA, and the effort required to plug and abandon the hole. Therefore preventing stuck pipes is far more cost effective than the most effective freeing procedures. Many researchers are working to identify the symptoms to reduce the risk of a stuck pipe. Due to the complexion of stuck pipeâ€™s symptoms and indicators, some researcher proposed artificial intelligence (AI) as the tool to predict stuck pipes. Although researches have been made to build systems employing artificial intelligence (AI) to avoid stuck pipe occurrences in oil and gas drilling operations, few works have been done for geothermal drilling operations. This paper describes a study that employed Artificial Neural Networks (ANN) approaches to predict stuck pipe incidents. Field data were collected from 6 geothermal wells drilled in North Sumatera fields. ANN was used to construct models to forecast stuck pipe incidents. The investigation found that ANN showed good performance with 84% accuracy and 74% recall for the limited training dataset. These ANN approaches provide good predictions that can help increase response time and accuracy in preventing stuck pipes.

Published: October 2022

Pseudomonas aeruginosa is one of the bacteria that causes infectious diseases. These bacteria show resistance to several types of antibiotics, therefore it is necessary to do alternative treatment using natural ingredients. Pegagan (Centella asiatica) leaves contain active substances such as saponins, tannins, alkaloids and flavonoids that function as antibacterial. This study aims to determine the antibacterial effectiveness of pegagan leaf extract (Centella asiatica) against the growth of Pseudomonas aeruginosa bacteria. This type of research is an experimental study with the disc diffusion method. Pegagan leaves were extracted by maceration method using 70% ethanol as a solvent. The pegagan extract obtained was then diluted using sterile distilled water at concentrations of 20%, 40%, 60%, 80%, 100%. Positive control used Penicillin G 10 g and negative control used sterile distilled water. The results showed that pegagan leaf extract (Centella asiatica) with concentrations of 20%, 40%, 60%, 80% and 100% had an average diameter of inhibition zone against Pseudomonas aeruginosa 7,6 mm, 10 mm, 12 mm, 12,6 mm and 16 mm. Positive control (Penicillin G 10 g) of 22 mm and negative control (sterile distilled water) did not inhibit the growth of Pseudomonas aeruginosa bacteria. Pegagan extract at concentrations of 60%, 80% and 100% were effective in inhibiting the growth of Pseudomonas aeruginosa bacteria, while concentrations of 20% and 40% were not effective in inhibiting the growth of Pseudomonas aeruginosa bacteria.

Antibiotics are one of the most widely used drugs in the world, therefore research on the use of antibiotics has been carried out, including research on the use of antibiotics associated with circadian rhythms for 24 hours. This literature study aims to explore research related to the effects of circadian rhythms on antibiotic drug levels. We conducted a search on two electronic databases, namely PubMed and Cochrane Library to search for articles related to the influence of circadian rhythms on antibiotics. This study does not limit the year, but the focus of this study is research conducted on humans and is a clinical study or randomized controlled clinical study. From the search, 28 articles were obtained from PubMed and 19 articles from the Cochrane Library. Of the total articles, six articles fall into the criteria of this study. One article is a test on levofloxacin, one article is a test on cefrozil, one article is a test on flomoxef, one article is a test on ciprofloxacin, and two articles are tests on tobramycin. From this study, it was found that the human body's circadian rhythm has an effect on antibiotics, either affecting the pharmacokinetic profile of the drug, or affecting the potential therapeutic effect of the antibiotic itself.
Keywords: antibiotics, chronopharmacology, circadian rhythm
