Authors: Catur Marina Bernaditha , Ahmad Pujiyanto Dika 
Published: November 2020

[ID] Peningkatan penggunaan beton konvensional mengakibatkan lapisan kedap air semakin luas, yang berimbas kepada turunnya muka air tanah dan terjadi banjir pada musim hujan. Hal ini dapat disiasati salah satunya melalui pengaplikasian cara-cara pembangunan yang ramah lingkungan, seperti penggunaan fly ash. Tujuan penelitian kali ini adalah untuk mengetahui presentase fly ash pada campuran beton agar menghasilkan kuat tekan dan porositas optimum. Pada penelitian ini digunakan fly ash sebagai bahan tambahan campuran dengan variasi sebesar 0%, 10%, dan 20% dari berat semen dan variasi faktor air semen (FAS) yang digunakan sebesar 0,3 , 0,4 , 0,5. Agregat kasar berukuran maksimum 20 mm, dengan jumlah sampel 36 buah silinder, 27 buah silinder untuk pengujian kuat tekan dan 9 buah silinder untuk pengujian porositas dilakukan pada usia 28 hari. Mutu beton rencana pada penelitian ini 10 MPa mengacu pada mutu bata beton. Pengujian kuat tekan beton yang dihasilkan menggunakan alat CTM (Compression Testing Machine) dan pengujian porositas menggunakan alat Falling Head Water Permeability Test yang megacu pada ACI 522R-10 yang dimodifikasi. Hasil ekperimen menunjukan nilai optimum kuat tekan dan porositas rata-rata dengan variasi FAS 0,3 : FA 10%, untuk umur beton 28 hari secara berturut-turut adalah 5,4 MPa dan 7,75 m3/s. Kesimpulan penelitian ini adalah komposisi paling optimum untuk penggunaan fly ash yaitu sebesar 10% dengan faktor air semen 0,3.
[EN] The increase in the use of conventional concrete resulted in a wider airtight layer, which resulted in the lowering of the groundwater level and flooding during the rainy season. One of the ways to overcome this is through the application of environmentally friendly development methods, such as the use of fly ash. The purpose of this research was to determine the percentage of fly ash ih concrete mixture to produce optimum compressive strength and porosity. In this study, fly ash was used as an additional mixture with variations of 0%, 10%, and 20% of the weight of cement and variations of the cement water factor (FAS) used were 0.3, 0.4, 0.5. The maximum size of coarse aggregate is 20 mm, with a sample size of 36 cylinders, 27 cylinders for compressive strength testing and 9 cylinders for porosity testing carried out at the age of 28 days.

Authors: Vasetskaya N. О. 
Published: November 2020

The processes of globalisation and internalisation in the world community, the development of high technologies and new industries, the digitalisation of the economy lead to the need for training with a fundamentally new set of competencies to meet the needs of customer organisations. The article is devoted to the study of cognitive competencies as key components in the structure of a university graduate’s personality in the knowledge-digital economy, which is in demand in the labour market. The article deals with the trend of changing the educational paradigm, based on updating the methodology of the modern educational process, including through the integration of educational, research and innovation activities as a strategy for the development of the modern economy. The necessity of inclusion in the list of key competencies of graduates. The author also discusses the concept of “cognitive competence” formulated by leading scientists involved in the study of this problem. The article presents the author’s model and structure of cognitive competencies developed for University graduates in the new economy, which is a set of development of mental, physical, emotional and spiritual intelligence. The author paid special attention to the fundamentally new role of the teacher in the educational process, in which the student does not just receive information from the teacher, but learns the methodology of independent “production” of knowledge.
Sanctions and Foreign Direct Investment: Damage to Russia and Sanctioning Countries
Authors: Kazantsev S. V. 
Published: November 2020

The volume and dynamics of foreign investments are formed under the influence of many conditions and circumstances. The author of this article examines the impact of one class of factors that determine the dynamics and geographical structure of Russia’s foreign direct investment inflows outflows. These are anti-Russian sanctions imposed by a group of States in 2014 to isolate the Russian Federation in the field of politics, finance and economy, science and technology, information and culture. For these countries, Russia is not a priority investment target. The share of the Russian Federation varied from two to five per cent, and rarely exceeded 10 per cent of the total volume of these countries foreign direct investment net outflows in 2007–2018. The author presented in this article the positive and negative aspects of foreign direct investment, their dynamics before and after the imposition of sanctions. In particular, the author shows that the reduction in the foreign direct investment net inflows from Russia to the sanctioning countries was less significant for the leading EU States — Germany, France and United Kingdom — than for many other sanctioning countries The cuts in Russia’s foreign direct investment net outflows had almost no impact on the United States who was the main initiator of anti-Russian sanctions.

Published: November 2020

The article presents the results of applying the elements of the object security research methodology in the study of one of the threats hanging over society — pandemic COVID‑19. In this particular object, the author of the article tried to show the general, inherent in the collective concept of “a national security threat”. Knowledge of a common for all threats (the general) characteristics and particular one to each of them allows us to organise the protection of the object better, prepare to stop the threat and eliminate the consequences of its emergence. Based on the Federal State Statistics Service of the Russian Federation official data, the author shows a deterioration of the state of public health and science in modern Russia. The article also presents a mathematical model, used by the author to calculate the results of two ways to slow the spread of coronavirus infection. The first way is the isolation of citizens, second — the use of personal protective equipment. In particular, the conducted research confirmed two well-known theoretical statements. First, in studying the process of emergence of threats and in estimating the damage caused by them, it is advisable to rely on the results of model calculations. Second, when choosing counteraction measures, it is reasonable to search for the best combination of them.

Published: November 2020

In this research, an analysis was carried out to develop a measuring instrument for seawater density in salt production using a microcontroller (Arduino Uno) and YL-69 sensor, this sensor was commonly used to measure soil moisture. The experimental method was used in this research to produce initial data in the form of resistance and seawater density values, then calculations are carried out using statistical methods to find equations and produce a constant variable that connects the resistance and seawater density values. The equation was used to compile the algorithm into Arduino Uno. As for the results of this research, From six experiments conducted, two experiments produced the same sea water density value between the actual and the predicted, namely the 2nd and 5th experiments, while for other experiments there was a difference between the actual and predicted values, however, it was not too significant, the difference occurs between the value range 0 ~ 1, to determine the level of error, use the Mean Square Error (MSE) with an error level of = 0.5 and Mean Absolute Error (MAE) with an error level of = 0.6. The contribution of this research is an algorithm that can predict the density value (baume) based on the resistance value obtained from the YL 69 sensor.
