Authors: Andayanie Wuye Ria
Published: January 2021

Soybean mosaic disease is wide spread throughout soybean-growing countries. Incidence of this disease in East Java is caused by Soybean mosaic virus (SMV) and cowpea mild mottle virus (CMMV).  This aim of study was to find the etiology of  disease at 14-28 days after planting (dap) on soybean.  Research was done by observing visual symptoms. Visual symptoms confirmed by infectivity test, serology assay,electron microscopy (EM) and molecular detection. Results from experiment indicated that soybean plants (14-28 dap) with  symptom  could be detected in infectivity test. Mechanical inoculation with symptomatic leaf extracts produced local lessions on Chenopodium amaranticolor. Positive results were obtained for Madiun, Ngawi, and Magetan samples when tested against antiserum of SMV in serological assay, however Ponorogo samples were not detected by serological assay. Electron microscopy was also done for the selected sample to confirm the result of positive results.  In EM observations, characteristic filamentous particles with modal length close to  900 nm  were observed in samples infected with SMV.  We detected an array of amplification products of expected size 1385 bp fragment of  cylindrical inclusion gene from Madiun, Ngawi, and Magetan isolates in former fields, but not detected in Ponorogo isolate. This result showed the existence of SMV of soybean seed transmission at 14-28 dap in Madiun, Magetan and Ngawi.

Published: January 2021

The implementation of the domestic liquid waste disposal control policy in Purwakarta Regency has not been implemented because there are no regulations regarding its management. So far, domestic wastewater is discharged directly into drainage channels / rivers due to the unavailability of facilities and infrastructure for domestic wastewater management, lack of public understanding of the impact of domestic wastewater on water pollution. In addition, there are no operational level regulations regarding the implementation of domestic wastewater management policies. The method used is a qualitative approach with information from policy implementers at the Environmental Agency and related sub-district. Analysis of policy implementation uses the George C. Edward III approach which includes communication, resources, dispositions and bureaucratic structures. The results showed that in order to solve the problem of implementing the domestic liquid waste disposal control policy, the Purwakarta Regency Government needs to carry out several actions in controlling domestic liquid waste disposal pollution to receiving water bodies. The steps that can be taken are optimizing the performance of limited human resources, provision of a budget, and cooperation between the government, the private sector and the community. Policy implementation can be carried out if Purwakarta Regency already has references including inventory data and identification of sources of domestic liquid waste pollutants, Standard Operational Procedure (SOP) for Domestic Wastewater Disposal Control, and regent regulations on domestic liquid waste management.

DEVELOPMENT OF SIMPLE, EASY AND INEXPENSIVE ONLINE SYSTEM FOR LIST OF PROPOSAL ASSESSMENT CREDIT SCORE OF WIDYAISWARA
Authors: Satria Wirawan Sri Mahendra
Published: January 2021

The current process of proposing and calculating credit number for Widyaiswara is felt to require an exceedingly difficult effort. Many costs must be incurred, especially to hold office stationery such as printing equipment, paper, ink, binder clips, and others. The next issue is how to provide a relatively large number of proposal files and a place for verification and evaluation. After the research is finished, the problem arises again when it will destroy the documents that have been examined.  This condition causes waste generation which is not environmentally friendly. An alternative solution for this is to use an online system of calculating credit numbers. However, the development and use of online system applications require considerable development, maintenance, and development costs. Based on research conducted using Microsoft Excel software combined with several software that provides unpaid facilities, a credit score calculation system application can be built for Widyaiswara that is simple, easy, and inexpensive. The results of trials conducted on the calculation of Widyaiswara BPSDM credit figures in DKI Jakarta Province gave very satisfying results, especially on increasing the speed of time and accuracy of proposals and assessments.

Published: January 2021

Volcanic ash contains minerals needed by soil and plants with the highest composition of total elements, namely Ca, Na, K and Mg, other macro elements in the form of P and S, while micro elements consist of Fe, Mn, Zn, Cu. The layer of volcanic dust that has the potential to contain nutrients for soil fertilization for agriculture can actually only be used about 10 years after the spread of volcanic ash. Soil fertilization can be accelerated if mixed with organic materials such as by using chicken manure fertilizer which has nutrients from chicken manure: N = 1.7%, P2O5 = 1.9%, K2O = 1.5%. Humic acid helps regulate clay and soil improvement, binds and transfers micro elements from the soil to plants, increases water absorption, and stimulates the development of microorganisms in the soil. Therefore, this study was conducted to make humic silica fertilizer in the planting medium by utilizing volcanic ash in combination with chicken manure mixed with soil. In this study apart from being a source of humic acid, chicken manure is also beneficial because it contains microorganisms which will be useful in accelerating the fertilizer incubation process. The composition of the fertilizer mixture used in this study is: volcanic ash sinabung: chicken manure: soil = 20: 50: 30; 30: 50:20; 40: 50: 10. The mixture is stirred evenly and then incubated for 30 days. After 30 days, the nutrient content of these fertilizers was tested and the highest content of the nutrients obtained in the combination was 20:50:30 namely: Organic C-1.35%, N-total 0.2%, P-available 20.16 ppm , K-available 0.527 me / 100g, C / N 6.75%, and humic acid contained in 3.925%

Coconut milk is a thick white liquid extracted from coconut produced from shredded coconut and then squeezed with water. Coconut milk is an ingredient produced from processed old coconut. Coconut milk can be used as food preparations or as herbal beauty ingredients. One of the advantages of coconut milk in the field of beauty is that it is very effective as a dandruff remover. By using old coconut milk as a dandruff remover we can get amazing results with natural ingredients without spending a lot of money. Coconut milk has many contents such as water content, protein and fat which are quite high as well as cow's milk. Coconut milk is rich in vitamins C, B, B-6, thiamine, niacin, folate, a number of minerals (calcium, magnesium, iron and phosphorus). Pure coconut milk only contains 54 percent water, 35 percent fat and 11 percent nonfat solids (approximately 6 percent carbohydrates, less than 4 percent protein and other solids) which are categorized as emulsions of oil in water. Coconut milk is known to be effective in eliminating dandruff, because coconut milk contains coconut oil containing Vitramin E and fatty acids that can eliminate and eradicate dandruff. You do this by using coconut oil as a massage oil to massage the scalp.

Published: January 2021

Knowing about metal coating (electroplating) is the electrodeposition of coatings or coatings attached to the electrodes to protect the substrate by giving surface properties and dimensions different from the base metal or finishing technique, by coating metal that is easily corroded (corrosion) with metals that are resistant to corrosion with electrical and chemical engineering. Whereas in Indonesian society the technique for metal coating is very familiar with the name of the gilding technique. In ancient times before electroplating and gilding were discovered to avoid corrosion of metals, the incorporation of metals such as copper with tin into bronze, copper with zinc into brass in addition to being resistant to corrosion also added to the beauty of color. Among the alloys above bronze is the oldest alloys that have been used by humans. With the development of the times, more modern gilding techniques were found to be a more practical method, namely electroplating, gilding with electrical and chemical processes that make metals resistant to corrosion. Metal coating is a scientific field which is one of the applications of electro chemical technology. Very closely related to the material science and technology, surface chemistry, physical chemistry, to the engineering. Various metals can be plating. The various metals are classified into five groups: "tumbal" coatings, decorative-protective coatings, engineered metal coatings, rare-use metals, and various types of alloys. All of these have their own characteristics, both advantages and disadvantages.

Assessing the effects of uncertainty and climate change on hydrological simulations across a permafrost gradient in North-Central Canada
Authors:   , Lilhare Rajtantra
Published: January 2021

Hudson Bay, a vast inland sea in northern Canada, receives the highest average annual freshwater from the Nelson River system among all other contributing rivers. A rapidly changing climate and flow regulation from hydroelectric developments alter Nelson River streamflows timing and magnitude, affecting Hudson Bay’s physical, biological, and biogeochemical state. Despite recent developments and advances in climate datasets, hydrological models, and computational power, modelling the Hudson Bay system remains particularly challenging. Therefore, this dissertation addresses crucial research questions from the Hudson Bay System (BaySys) project by informing how climate change impacts variability and trends of freshwater-marine coupling in Hudson Bay. To that end, I present a comprehensive intercomparison of available climate datasets, their performance, and application within the macroscale Variable Infiltration Capacity (VIC) model, over the Lower Nelson River Basin (LNRB). This work aims to identify the VIC parameters sensitivity and uncertainty in water balance estimations and investigates future warming impacts on soil thermal regimes and hydrology in the LNRB. An intercomparison of six climate datasets and their equally weighted mean reveals generally consistent air temperature climatologies and trends (1981–2010) but with a prominent disagreement in annual precipitation trends with exceptional wetting trends in reanalysis products. VIC simulations forced by these datasets are utilized to examine parameter sensitivity and uncertainties due to input data and model parameters. Findings suggest that infiltration and prescribed soil depth parameters show prevailing seasonal and annual impacts, among other VIC parameters across the LNRB. Further, VIC simulations (1981–2070) reveal historical and possible future climate change impacts on cold regions hydrology and soil thermal conditions across the study domain. Results suggest that, in the projected climate, soil temperature warming induces increasing baseflows as future warming may intensify infiltration processes across the LNRB. This dissertation reports essential findings in the application of state-of-the-art climate data and the VIC model to explore potential changes in hydrology across the LNRB’s permafrost gradient with industrial relevance of future water management, hydroelectric generation, infrastructure development, operations, optimization, and implementation of adaptation measures for current and future developments.
Volba dodavatele elektřiny v ČR v roce 2020 z pohledu nákladů na spotřebu elektřiny pro domácnosti a pro podnikatelský maloodběr – simulační model
Authors: Kuncová Martina
Published: January 2021

The situation on the Czech electricity market from the point of view of small customers or households is confusing every year. Although information on electricity consumption prices for households and small businesses is already freely available on the Internet (web pages of the Electricity Regulation Office), understanding the rules for calculating electricity consumption costs is still not easy for ordinary small consumers. For small entrepreneurs, the question often arises as to whether tariffs intended for households can be used for the electricity consumption, or whether it is necessary or appropriate to switch to tariffs for small business consumption. This article is focused on the analysis of the offer of electricity suppliers for the year 2020 in the Czech Republic from the point of view of the distribution rate D25d for households, resp. C25d for entrepreneurs in order to assess differences in the cost of electricity consumption and to select those products and suppliers for which the annual cost of electricity consumption is minimal. Monte Carlo simulation, where the monthly electricity consumption is generated (normal probability distribution), is used for the analysis together with the basics of multicriteria decision making, especially the non-dominance testing principle. The results show that the differences in the annual electricity consumption costs can be around 15% and the tariff rates for households are cheaper than the tariff rates for the entrepreneurs (also here the difference in annual costs can be around 15-20%).

Обычаи избегания в традиционной семье коренных народов Нижнего Амура и Сахалина: середина XIX – начало XX вв.
Authors: Фадеева Е. В.
Published: January 2021

В статье путём сравнительно-исторического метода анализируются обычаи избегания между различными категориями родственников и свойственников в традиционной семье коренных народов Нижнего Амура и Сахалина. Представленные материалы позволяют сделать следующие выводы: во-первых, ограничения устанавливались преимущественно для женщины в её отношениях к родственникам мужа, и в меньшей степени для мужчины в отношениях к родственникам жены, что вполне объяснимо при той роли, которую играли в семье мужчины и женщины. Во-вторых, ограничения прежде всего прилагались к старшим родственникам мужа или жены, коими являлись мужчины. В-третьих, запреты на общение распространялись, главным образом, на от- ношения между старшими родственниками и младшими (например, старший брат и младшая сестра, отец и дочь, свёкор и невестка). The article, using the comparative historical method, analyzes the customs of avoidance between different categories of relatives and relatives in the traditional family of indigenous peoples of Lower Amur and Sakhalin. The materials presented allow us to draw the following conclusions: firstly, restrictions were set mainly for a woman in her relations with her husband’s relatives, and to a lesser extent for a man in relations with her wife’s relatives, which is quite understandable with the role that men and women played in the family. Secondly, restrictions, first of all, were applied to the elder relatives of the husband or wife, of whom men were. Thirdly, prohibitions on communication extended mainly to relations between older relatives and younger ones (for example, older brother and younger sister, father and daughter, father-in-law and daughter-in-law).

The methodology is a way to manage an organization's receivables by providing prospective and estimated information at the contract stage to minimize potential risks when executing agreements.
Conclusions. The proposed algorithm of prospective assessment of the creditworthiness of counterparties will help reduce the risk of non-repayment of receivables and develop minimum requirements, which the counterparty must meet in order to obtain a loan. The results of the study can be applied in the organization's practical activities as part of the development of receivables management activities.

Authors: SMIRNOV Valerii V.
Published: January 2021

Subject. The article focuses on the substance of the Central Bank of the Russian Federation.
Objectives. The study analyzes trends in aggregated financial and economic indicators of today’s Russia, and reveals the substance of the Central Bank.
Methods. The study is based on the systems approach and methods of statistical, neural network and cluster analysis.
Results. I demonstrate the positioning of the Central Bank and its function. The Central Bank was found to depend on the market, being, on the one hand, its vehicle, and, on the other hand, its product (as part of monetary relations). Therefore, the substance of the Central Bank shows up in the monetary relations. The article illustrates the substance of the Central Bank, which is to ensure the stable growth in the accounting balance notwithstanding a drop in the national exchange rate, finance the cash ratio, maintain a growth in the interbank interest rate and yield on government bonds. The above functions shape the monetary relations. The official inflation targeting policy of the Central Bank should be viewed through the real effective exchange rate.
Conclusions and Relevance. Understanding the contemporary substance of the Central Bank unveils the mechanism of monetary relations and opportunities for maintaining the stability of the Russian capitalism within the dynamics of aggregated financial and economic indicators. The findings contribute to the existing knowledge and advance the competence of public authorities to make administrative decisions on the regulatory responsibility of the Central Bank of the Russian Federation for its performance.

Rola edukacji w rozwoju społeczno-gospodarczym i kulturowym
Authors: Zioło Zbigniew
Published: January 2021

W procesie wkraczania w informacyjną fazę rozwoju coraz bardziej zaznaczać się będą nowe tendencje w zakresie zmian struktur zawodowych, społecznych i kulturowych. Będą one konsekwencją nasilających się procesów automatyzacji i robotyzacji w działalności produkcyjnej, usługowej i zarządzaniu. Wpłynie to na stopniowe ograniczanie rozmiarów zatrudnienia i likwidację wielu zawodów. Równocześnie pojawiać się będzie coraz większe zapotrzebowanie na kadry o nowych umiejętnościach zawodowych (technicznych, organizacyjnych, zarządzania) oraz rozwiązywania pojawiających się nowych problemów społecznych i kulturowych. Wpływa to na rosnącą rolę edukacji m.in. w zakresie przedsiębiorczości oraz przygotowywania poszczególnych osób i społeczeństwa do nowych wyzwań cywilizacyjnych. Towarzyszy temu pojawianie się nowych przesłanek i tendencji rozwoju społeczno-gospodarczego i kulturowego oraz konieczność działań na rzecz przyspieszania procesów rozwojowych, które omówiono w artykule. W końcowej jego części przedstawiono opinie przedsiębiorców dotyczące funkcjonowania firm.
Kształcenie praktyczne w uczelniach wyższych w ocenie studentów kierunku ekonomia społeczna
Authors: Szyja Paulina , Maciejewski Wojciech
Published: January 2021

W artykule zaprezentowano, jak studenci oceniają praktyczny wymiar kierunku ekonomia społeczna. W celu realizacji badania przedstawiono prawne aspekty opisujące praktyczny wymiar kształcenia oraz zapytano, w formie ankiety online, studentów kierunku ekonomia społeczna o opinię na temat praktycznego wymiaru studiowania. Badani odpowiadali na pytania związane z oceną programu studiów oraz ich zaangażowaniem w działania pozadydaktyczne. Poproszono ich także o rekomendacje związane z praktycznym kształceniem. Dopełnieniem badań były pytania odnoszące się do oczekiwań studentów względem wybranego kierunku, ogólnego zadowolenia ze studiów i określenia, jaki mają poziom wiedzy w porównaniu z początkiem studiów. Za największe braki w programie studiów badani uznali małą liczbę przydatnych w praktyce przedmiotów i niewystarczającą liczbę przedmiotów ekonomicznych. Duża część badanych – 38,3% – nie była też w stanie określić, czy jej oczekiwania dotyczące kierunku studiów zostały spełnione. Zdecydowana większość badanych określiła swój stan wiedzy jako większy niż przed rozpoczęciem studiów. Wyniki badań sugerują, że należałoby upraktycznić proces kształcenia oraz zwiększyć liczbę wizyt studyjnych. Jednak studenci, poza głównie pracą zawodową, nie podejmowali indywidualnej inicjatywy w zdobywaniu praktycznego doświadczenia – tylko niewielki ich odsetek angażował się w wolontariat i działania w kołach naukowych, również niewielka liczba studentów postulowała za zwiększeniem liczby praktyk zawodowych.

Analysis of Investment Activities of Enterprises in Poland
Authors: Piątkowski Marcin J.
Published: January 2021

The impact on the development of the economy and enterprises themselves is made possible by investments as they are one of the main components of GDP. An increase in enterprise investments demonstrates the good financial condition of economic entities, is a positive signal about the state of the economy and gives information about its development. The subject of this article is the impact of enterprises on the economy and its importance in Poland by analysing both investment itself and the investment rate. The analysis was carried out at a regional level as well as in relation to other EU member states. The aim is to analyse the investment activities of Polish enterprises, with particular emphasis on the change as well as their size and type. The research is based on a critical analysis of the literature and an analysis of secondary statistical data, covering the period from the first full EU program from 2007, and extended in accordance with the n+2 funding rule until 2015. The analyses show that despite growing investment among Polish enterprises, compared to the rest of the EU, the value of expenditure on fixed assets is still low as the average value made in the private sector among EU countries is 70% higher. At the same time, the growing level of investment value among private businesses over the nine years should be emphasized. There is also a very large regional variation in the level of investment growth per working-age capita over the period considered.
Key Factors Hindering the Development of Education in Sub-Saharan Africa – Scoping Review
Authors: Krzykawska Aleksandra , Żur Agnieszka
Published: January 2021

Lack of effective education is often highlighted as one of the main factors hindering the development of African countries. Most of Sub-Saharan Africa exhibit some of the lowest national GDP indexes and the lowest literacy rates and additionally account for more than half of out-of-school children globally. Despite gradually implemented reforms, Sub-Saharan educational systems still face numerous challenges and do not meet global standards. Although the number of articles referring to Sub-Saharan education has been growing in recent years, they remain fragmented and do not provide a synthetic analysis of the main factors shaping education in the region. This article addresses this gap in the understanding of impediments to education in Africa, aiming to connect existing discussions to identify the barriers in the Sub-Saharan education systems. Based on an analysis of a selection of existing research evidence, statistics and reports, this study delivers a holistic analysis of education systems in Sub-Saharan Africa along with their determining factors. This study contributes to a better understanding of Sub-Saharan education as one of the critical factors in the social and economic development of this region.
