Keadaan darurat di jalan tol merupakan sebuah kejadian yang terjadi secara tiba-tiba dan diperlukan proses penanganan yang cepat dan tepat. Nomor hotline di jalan raya masih digunakan sebagai sistem pelaporan, tetapi sering mengalami nada sibuk dan hanya mengandalkan mode GSM. Tujuan dari penelitian ini adalah membuat inovasi untuk mempermudah melaporkan keadaan darurat dengan cepat dan tepat di jalan tol. Teknologi internet dipilih karena internet merupakan komunikasi global jarak jauh yang terbuka dan GSM dipilih karena tidak semua lokasi terdapat jaringan internet. Cara kerja sistem ini yaitu pengguna jalan tol menekan salah satu push button sesuai keadaan darurat yang dialami, lalu mikrokontroler akan mengaktifkan GPS untuk mendeteksi lokasi pelapor, dan mengirimkan ke instansi terkait melalui aplikasi android, SMS, atau e-mail. Ketika data berhasil dikirim, maka pada LCD menampilkan pemberitahuan. Pada pengujian didapatkan hasil kesalahan GPS sebesar 34%, sedangkan push button sebesar 0% , proses pengiriman dan penerimaan data memiliki toleransi waktu yang tidak lebih dari 15 detik. Dari pengujian dapat disimpulkan bahwa realisasi alat dan aplikasi sudah sesuai dengan spesifikasi yang dirancang.

Published: January 2022

Ketersediaan air sumur yang terbebas dari kontaminan organik dan zat mineral masih menjadi permasalahan di beberapa daerah di Indonesia. Pada umumnya, air sumur diolah secara fisik dengan menggunakan sand filter dan adsorben (karbon aktif atau zeolit) atau integrasi keduanya. Walaupun prosesnya sederhana, produk air belum memenuhi standar baku mutu air minum. Penelitian ini mengusulkan teknologi terintegrasi ultrafiltrasi berbasis polisulfon (UF), karbon aktif (KA), dan resin penukar ion (Ion Exchange/IE) sebagai alternatif pengolahan air sumur menjadi air baku untuk minum. Membran UF memiliki fluks permeat sebesar 42 L.m-2h-1. Hasil analisa menggunakan model Hermia menunjukkan bahwa fouling yang terbentuk didominasi oleh fouling total dan standard dengan nilai R2 masing-masing sebesar 0.8989 dan 0.8952. Selama 2 (dua) jam proses filtrasi, penurunan fluks permeat sebesar 19%. Berdasarkan data hasil analisa produk air, unit UF-KA mampu menurunkan kesadahan, zat organik, zat besi, dan kontaminan lainnya hingga di bawah nilai ambang batas kontaminan untuk standar baku mutu air minum. Namun konsentrasi senyawa mangan masih sebesar 0,601 mg/L di atas ambang batas standar (0,4 mg/L). Dengan penambahan unit IE setelah proses UF-KA, produk air yang dihasilkan memenuhi standar baku mutu air minum. Penyisihan turbiditas, besi, dan mangan untuk unit UF-KA-IE adalah masing-masing sebesar 95,9%; 99,9%; dan 72,5%.

Meinungskrise und Meinungsbildung. Eine Philosophie der Doxa
Authors: Bermes Christian
Published: January 2022

Die Antworten scheinen klar zu sein, wenn es um Meinungen geht: Meinungen sind privat, subjektiv, beliebig oder willkürlich. Werden Meinungen dem Wissen gegenübergestellt, erscheinen sie als ein Provisorium, das möglichst schnell überwunden werden muss, damit sinnvoll von Erkenntnis gesprochen werden kann. Gleichwohl müssen wir mit Meinungen umgehen, gerade die Herausforderungen der Sozialen Medien zeigen dies aufs Neue. In seinem Essay entwickelt Bermes in Auseinandersetzung mit Wittgenstein und im Anschluss an das phänomenologische Projekt einer Rehabilitierung der Doxa Bausteine zu einer Theorie wohlfundierter Meinung. Er diagnostiziert einen Mythos, der sich um das Meinungskonzept entwickelt hat, und erörtert die Doxa im Ausgang von einem Verständnis des Exemplarischen. Meinungen sind nicht einfach beliebig, subjektiv oder willkürlich. Auch Meinungen unterliegen Qualifikationsmerkmalen. Dies hat sowohl Auswirkungen für die Philosophische Anthropologie als auch für dasjenige, was als öffentliche Meinung bezeichnet wird.

Authors: Kumar Ajit , Priyadarsini Amrita
Published: January 2022

Aim/Purpose: A literature review is often criticized for the absence of coherent construction, synthesis of topics, and well-reasoned analysis. A framework is needed for novice researchers to organize and present information obtained from the literature review.

Background: Information and communication technologies advancement have yielded overwhelming information. The massive availability of information poses several challenges, including storage, processing, meaningful organization, and presentation for future consumption. Information System Researchers have developed frameworks, guidelines, and tools for gathering, filtering, processing, storing, and organizing information. Interestingly, information system researchers have vast information that needs meaningful organization and presentation to the research fraternity while conducting a literature review on a research topic.

Methodology: This paper describes a framework called LACTiC (Location, Author, Continuum, Time, and Category) that we adapted from another framework called LATCH (Location, Alphabetical, Time, Category, and Hierarchy). LATCH was used to organize and present information on e-commerce websites for seamless navigation. We evaluated the LACTiC framework.

Contribution: Information System Researchers can use the LACTiC framework to organize information obtained from literature review.

Findings: The evaluation reveals that most researchers from information systems organize information obtained from the literature review category-wise, followed by continuum, author, time, and location.

Recommendation for Researchers: Overall, the framework works well and can be helpful for researchers for an initial idea for organizing information obtained from the literature review.

Future Research: To conceptualize the framework, the study was carried out using Information Systems related literature. To generalize the proposed framework, we may suggest that the study can be extended to other areas of business management, such as marketing, finance, operation, decision sciences, accounting, and economics.

Community activities during the pandemic due to the stay at home policy resulted in an increase in the remaining results of activities. As a result, untreated household wastewater will have a negative impact on the surrounding waters and can become a source of disease for the community. The main purpose of this service is to educate and provide skills to the community to treat household wastewater in Jongso Hamlet, Wotan Village. The main material used for wastewater treatment is alum. This is because alum is a coagulant that can bind impurities in water. This service activity is carried out by socializing through online audio-visual media, namely Youtube, while the training is carried out directly at the stage of processing household liquid waste to the Dukuh Jongso community, and activity evaluation indicators are based on participant responses to socialization and training. The results of the implementation showed that the participants were enthusiastic in the socialization and training. This activity is also effective in educating the public, especially about public awareness of the surrounding environment. It is hoped that the community will continue to be committed to improving their knowledge and skills in protecting the surrounding environment. The community care movement for the surrounding environment is expected to continue to be applied independently and disseminated to other communities.

Published: January 2022

This mini-review summarizes the available information regarding the impact of caloric restriction (CR) and/or intermittent fasting (IF) on bone health. CR and IF are dietary interventions used in rehabilitative healthcare for augmenting weight loss and also proposed for recovery of conditions such as stroke and heart failure. CR restricts the total number of calories rather than different food groups or periods of eating. In contrast, IF severely restricts caloric intake for a period of time followed by a period of ad libitum intake. Here, we discuss the available information regarding the impact of these rehabilitation diets on bone metabolism, highlighting areas of consistency and discrepancy and suggesting future areas of study to advance the understanding of CR and/or IF on bone health.

Hydrodynamic Performance of Open-frame Deep Sea Remotely Operated Vehicles Based on Computational Fluid Dynamics Method
Authors: Li Qianrong , Zhang Baoji
Published: January 2022

The resistance performance and motion stability of deep sea remotely operated vehicles (ROVs) subjected to underwater motion conditions are studied on the basis of the unsteady Reynolds-averaged Navier-Stokes method combined with the six-degree-of-freedom equation of motion to quickly and accurately predict them. In the modeling process, we consider the complexity of ROV geometry and thus reduce the model to a series of regular geometries to maximize the position and weight of the original components. The grid and value slots of an ROV are divided, and the surface is reconstructed. The forward, backward, transverse, floating, and submerged resistance of ROVs are simulated and compared with existing experimental forces to determine the accuracy of the calculation method. Then, the oblique navigation of the ROV on the horizontal and vertical planes is studied. Furthermore, the motion response of the ROV to direct horizontal motion, heave, pitch, and yaw are studied. The force, moment, and motion time curves are obtained. The stability of ROV motion is analyzed to provide technical support for the safety of ROVs.

The usage of power system multi-model forecasting aided state estimation for cyber attack detection
Authors: Lukicheva I. A. , Kulikov A. L.
Published: January 2022

THE PURPOSE. Smart electrical grids involve extensive use of information infrastructure. Such an aggregate cyber-physical system can be subject to cyber attacks. One of the ways to counter cyberattacks is state estimation. State Estimation is used to identify the present power system operating state and eliminating metering errors and corrupted data. In particular, when a real measurement is replaced by a false one by a malefactor or a failure in the functioning of communication channels occurs, it is possible to detect false data and restore them. However, there is a class of cyberattacks, so-called False Data Injection Attack, aimed at distorting the results of the state estimation. The aim of the research was to develop a state estimation algorithm, which is able to work in the presence of cyber-attack with high accuracy.

METHODS. The authors propose a Multi-Model Forecasting-Aided State Estimation method based on multi-model discrete tracking parameter estimation by the Kalman filter. The multimodal state estimator consisted of three single state estimators, which produced single estimates using different forecasting models. In this paper only linear forecasting models were considered, such as autoregression model, vector autoregression model and Holt’s exponen tial smoothing. When we obtained the multi-model estimate as the weighted sum of the single-model estimates. Cyberattack detection was implemented through innovative and residual analysis. The analysis of the proposed algorithm performance was carried out by simulation modeling using the example of a IEEE 30-bus system in Matlab.

RESULTS. The paper describes an false data injection cyber attack and its specific impact on power system state estimation. A Multi - Model Forecasting-Aided State Estimation algorithm has been developed, which allows detecting cyber attacks and recovering corrupted data. Simulation of the algorithm has been carried out and its efficiency has been proved.

CONCLUSION. The results showed the cyber attack detection rate of 100%. The Multi-Model Forecasting-Aided State Estimation is an protective measure against the impact of cyber attacks on power system.

Authors: Chervonenko A. P. , Kotin D. A. , Rozhko A. V.
Published: January 2022

PURPOSE. To develop a variant of the algorithm for the automatic input of the reserve, which consists in transferring the load in case of emergency situations, to make a simulation model in the MatLab® environment corresponding to the developed generalized electrical scheme of the system.

METHODS. When solving the problem, the method of digital modeling was used, which consists in the maximum approximation of the system under study to a real object, implemented by means of MatLab.

RESULTS. It is proposed to study the methods of synthesis of digital models of compensation of voltage drops by the example of a study of an automatic reserve transfer system, demonstrating an approach to modeling this system. When developing models in the MatLab environment, the parameters of real technical elements and devices and their digital analogues are taken into account. The issue of creating a digital model of an electric drive system, including a model of an asynchronous motor with a short-circuited rotor, is considered. The result, after final refinement, can be used to design a real system in production conditions.

CONCLUSIONS. The developed model of the automatic transfer switch system is operable, the time indicators are satisfactory for systems that do not make excessive demands on performances and time intervals. For systems that are sensitive to current inrushes during load transfer, some improvements are required, which are reduced to the implementation of a high-speed automatic switch system. The development of this system is currently at the research stage, namely, the compilation of a load transfer logic that takes into account the phase matching of electrical circuits.

THE PURPOSE. This paper considers the problem of relay protection functioning when the current transformer reaches the saturation mode which is provided by transient processes.

METHODS. MATLAB Simulink software environment allows reproducing the method of statespace representation by using structural blocks. The model is verified by comparison the time to saturation, obtained by calculation and according to the graphical data of the model. The separation of variables method extracts and graphically displays the investigated components.

RESULTS. This paper reveals that applying the requirements of IEC 61869-2:2012 standard, which determines the worst combination of series of unfavorable factors for current transformers in transient mode, can influence a serious impact on the correct operation of relay protection based on current, reactance or differential principle of action. Saturation of the current transformer can lead to both negative results: false operation of relay protection devices and their failure.

CONCLUSION. According to the results of the study, it was determined that the presence of a DC component in the primary short-circuit current has the greatest effect on the protection operation. The delays in the restoration of the RMS value of the short-circuit current reached up to 0.3 seconds, which is comparable with the response time of the second protection zones for microprocessor-based relay protection devices. The DC component of the primary current and the presence of residual magnetic induction of the current transformer provides the largest content of the magnetization current, the largest angular error and also the largest content of the second harmonic component in the secondary short-circuit current.

Published: January 2022

In any practical field, tensions always exist between the group that views theoretical study as necessary and those who consider it pointless: likewise in the case of translation. Translation often places most of its emphasis on its practical aspects. The theoretical aspect of translation is often marginalized in professional settings. Nevertheless, in the context of translator training, translation theory is as an essential area, which needs to be studied and explored. This study investigated the views of 5th- and 7th-semester students of English Department at a private undergraduate educational institution in Jakarta, Indonesia, on translation theory. The class Theory of Translation is the only official locus for instruction in theories of translation at the target institution. The results of this study may provide several benefits, including the aiding the creation of syllabuses for and teaching translation theory. The author used a questionnaire to acquire the data needed to address the research questions. The results of this research revealed that most students in the 5th and 7th semester of English study in Jakarta, Indonesia, have a positive perception of translation theory, believing that it is essential for translation practice. Moreover, they also considered that translation theory could provide solutions for issues in the practice of translation.

The article is devoted to the problem of the validity of determining the wear of component parts when calculating the damage caused to a vehicle due to its deterioration. The authors address the legal line of arguments of the differentiated approach when deciding on the need to consider wear and tear. They also make suggestions on its practical reflection in forensic expert opinions. Finally, it is highlighted that when making decisions regarding wear and tear, it is essential to consider the method of compensation for damage caused and official legal information.The authors justify the necessity to use the provisions of the methodological recommendations developed in the Federal State Budgetary Institution of the Russian Federation under the Ministry of Justice of the Russian Federation in the calculations, which will allow experts to formulate categorical and not relative or multivariate conclusions.
