Because many things cause the extinction of a language, namely there are four: First, the speakers think of themselves as socially inferior. Second, attachment to the past. Third, the traditional and Fourth side, because economically life is stagnant. But apart from all that, there are also efforts that can be made to prevent and prevent the extinction of language through the inculcation of awareness of language preservation, including local language subjects at every level of education.

Implementasi Teori Pembelajaran Blended Learning dalam Menyeimbangkan Kapabilitas Belajar pada Era Digital (Studi Kasus di Prodi PAI Universitas Alma Ata Yogyakarta)
Authors: Rohman Abdul
Published: September 2020

Blended learning learning pattern is a combination of conventional learning patterns and e-learning. The concept of blended learning applied at the University of Alma-ata uses the WEB system with a composition of blended learning patterns, 75% for conventional learning and 25% for e-learning. The implementation of the blended learning theory in balancing learning capabilities includes two classifications. Learning capabilities include five aspects, namely verbal information, cognitive strategies, intellectual skills, attitudes and motor skills. The five capabilities are divided into two classifications of blended learning theory, namely verbal information and cognitive strategies included in the classification of e-learning, this is because it places more emphasis on the knowledge aspect. Then the three other aspects fall into the classification of conventional learning, this is because the conventional learning process is carried out directly and face-to-face between educators and students, educators become a central figure in learning and play a role not only in conveying science but as explained by Alghazali, educators are al -mudaris, al-mualim, al-muaddib and al-walid.

ABSTRACTThis research was basically conducted to improve students’ understanding of mathematical concepts and mathematical communication skills both verbally and non-verbally using the Rally Coach learning method. In addition, the main purpose of this study is to examine and analyze the relationship between students’ understanding mathematical concepts and mathematical communication. Therefore, the authors first design instruments to measure students’ understanding of mathematical concepts and mathematical communication skills that have been adapted to indicators. This study is based on correlational research method. The instrument was tested to see its validity and reliability using the Cronbach Alpha formula. The results show that the application of the Rally Coach learning model has a positive influence in improving students’ understanding of mathematical concepts and mathematical communication. The results of the analysis by statistical testing with Pearson correlation show that there is a relationship between understanding mathematical conception and mathematical communication skills, but the relationship is not so strong. This can be seen from observations made by authors, some students are able to understand mathematical problems, but are not fully able to communicate verbally.Keywords: mathematical communication; mathematical conceptual understanding; Pearson correlation; rally coach; validity and reliability test.

Published: September 2020

В статье рассматривается определение нелинейных сил, возникающих при продольной качке судов (продольно-горизонтальной, вертикальной и килевой) на основании трехмерной потенциальной теории. Для нахождения нелинейных сил, требуется определение потенциалов второго порядка малости. Решение основано на методах малого параметра, интегральных уравнений и функций Грина для случая глубокой воды и ограниченной глубины (при H→∞). При определении потенциалов второго порядка учитываются нелинейные граничные условия на свободной поверхности жидкости и на смоченной поверхности судна. На основании изложенного метода разработаны две программы, использующие разные функции Грина.. Приводятся результаты расчетов сил и моментов для двух разных судов. Показано практически полное согласование результатов при использовании различных функций Грина. Приведено сравнение с результатами по двумерной теории. Проведены расчеты нелинейных сил на различных курсовых углах. Показано влияние курсового угла на отдельные составляющие нелинейных сил. Показано значительное влияние потенциалов второго порядка в образовании нелинейных сил, возникающих при всех видах продольных колебаний.

Published: September 2020

Применение CFD-пакетов для моделирования работы гребных винтов является одним из современных направлений исследований. Несмотря на достигнутые успехи, имеют место расхождения результатов, получаемых разными исследователями. С целью преодоления этих трудностей на международном уровне был проведен ряд сопоставительных расчетов гребных винтов. В данной работе представлена схема расчета силовых и кавитационных характеристик гребного винта в пакете OpenFOAM. Валидация расчетной схемы осуществляется на примере сопоставительных расчетов выполненных в рамках симпозиума SMP’11 и под эгидой пропульсивного комитета ITTC. Показано, что предложенная схема расчета не уступает аналогам в части расчета кривых действия модели гребного винта, оценке ее кавитационных характеристик и прогнозирования характеристик натурного гребного винта. Так же показано, что принципиальным для получения достоверных результатов является правильное построение сетки, имеющей высокое разрешение.

The use of CFD packages for modeling the operation of propellers is one of the modern research areas. Despite the success achieved, there are discrepancies in the results obtained by different researchers. In order to overcome these difficulties, a number of comparative calculations of propellers have been made at the international level. This paper presents a scheme for calculating the thrust, torque and cavitation characteristics of a propeller in the OpenFOAM package. Validation of the calculation scheme is carried out on the example of comparative calculations performed in the framework of the SMP’11 Symposium and under the auspices of the ITTC propulsive Committee. It is shown that the proposed calculation scheme is not inferior to its analogues in terms of calculating the action curves of the propeller model, evaluating its cavitation characteristics and predicting the characteristics of a full-scale propeller. It is also shown that the principle for obtaining reliable results is the correct construction of a high-resolution grid.

This paper presents a video codec with an adaptive method for scanning spectral transformants based on the use of three-dimensional (3D) discrete cosine transformations. The codec has a low computational complexity and high resistance to transmission errors over the communication channel and is designed for mobile devices. A codec is a device that sequentially performs a discrete cosine transformation to eliminate spatial redundancy within a frame and temporal inter-frame redundancy in a sequence of frames, taking into account the speed of movement of objects in images of marine subjects. The results of modeling algorithms for encoding and decoding video information for various video streams obtained from surveillance cameras are presented. The results of testing algorithms for encoding and decoding images in the form of graphs of the dependence of the recovery accuracy on the speed of transmission of compressed video data and the dependence of accuracy on the complexity of image compression devices are obtained.

Предложена авторская трактовка понятия «конкурентоспособность судоходной компании» как способности последней производить такой комплекс интегрированных транспортных продуктов, потребительская привлекательность которого не меньше, чем потребительская привлекательность комплекса интегрированных транспортных продуктов судоходных компаний-конкурентов. При этом под «потребительской привлекательностью интегрированного транспортного продукта» понимается способность интегрированного продукта демонстрировать определенное отношение его качества к цене. В свою очередь «интегрированный продукт» – это комплекс основных и дополнительных продуктов деятельности предприятия, которые нацелены на удовлетворение различных потребностей покупателя и связаны друг с другом устойчивыми ассоциативными связями. Причем речь идет о продуктах различного масштаба: интегрированные продукты – продукты – микропродукты. В основе предлагаемой методики оценки конкурентоспособности судоходной компании лежит теория выбора товаров на рынке (теория принятия решения о покупке), содержанием которой являются программы (алгоритмы) выбора покупателем товаров на рынке. Разработанная методика оценки конкурентоспособности судоходной компании включает в себя пять этапов. В качестве ключевого показателя конкурентоспособности судоходной компании используется показатель конкурентоспособности комплекса интегрированных продуктов судоходной компании.

An author's interpretation of the notion “competitiveness of a shipping company” is proposed as the latter’s ability to produce such a complex of integrated transport products whose consumer attractiveness is no less than the consumer attractiveness of a complex of integrated transport products of competing shipping companies. At the same time, “consumer attractiveness of an integrated transport product” means the ability of an integrated product to demonstrate a certain ratio of its quality to price. In turn, an “integrated product” is a complex of basic and additional products of a manufacturer’s activities, which are aimed at meeting the various needs of the buyer and are linked together by stable associative relations. And we are talking about products of various sizes: integrated products - products - microproducts. The proposed methodology for assessing the competitiveness of a shipping company is based on the theory of the choice of goods on the market (the theory of making a purchasing decision). This is a theory, the content of which is the program (algorithms) of the choice by the buyer of goods on the market. The developed methodology for assessing the competitiveness of a shipping company includes five stages. As a key indicator of the competitiveness of the shipping company, the competitiveness indicator of the complex of integrated products of the shipping company is used.

The number of unemployment rate in Indonesia that has been decreasing is caused by the growth of entrepreneurship in Indonesia, which is proven by the number of startup businesses in Indonesia reaching the sixth highest worldwide. Nevertheless, startup businesses have high failure rate, where two of three established startup businesses cannot sustain. With purpose to find out the reason of this phenomenon, this research aims to find out whether entrepreneurial passion and opportunity awareness have significant effects to startup businesses’ sustainability. This research uses the startup businesses of Ciputra University’s 2015 batch students that have been running for minimum 2 years as the sample. These startup businesses are aimed to be able to represent startup businesses since from more than 200 startup businesses established, only 42 startup businesses that sustain. Questionnaires are distributed to the samples using 5-points Likert-scale, and the data collected is then analyzed using Multiple Linear Regression. The result shows that entrepreneurial passion has significant effect toward startup business sustainability, but it does not go the same way with opportunity awareness. Opportunity awareness does not affect significantly toward startup business sustainability since it needs to be converted into opportunity recognition and opportunity exploitation to give significant effects.
