Published: June 2023

A decision support system, also known as a decision support system (DSS), is an interactive information system that offers data, models, and information. DSS is used as a decision aid in semi-structured and unstructured situations where there is no clear decision-making procedure. Determining the preferred major is one of the challenges in universities. The purpose of determining the most popular major is to improve the quality and services provided to students in each department, which is a crucial objective for universities. Currently, Universitas Sari Mulia determines the most popular majors based on qualitative data, which makes the determination of the most popular majors themselves inaccurate; therefore, a method capable of managing data on the selection of the most popular majors is necessary. In this study, the Simple Additive Weighting (SAW) technique will be utilized. This method is used to compare each criterion with one another in order to determine the most popular majors at Sari Mulia University and to evaluate each department.

Methodology of financial risks management at the enterprises of forest industrial complex
Authors: YARMOLIUK Аnatolii
Published: June 2023

The essence of financial risk is considered, the sources of uncertainty are singled out, and the definition of financial risk is established. The theoretical aspects of the financial risk management system and the mechanism of their implementation are characterized. The types of financial risks are defined. The main goal of the financial risk system is highlighted; it is the maintenance of the stability of the enterprise in the process of its development, the minimization of losses in economic operations. Therefore, it should solve the following tasks: identifying the most significant threats and identifying weaknesses in the company’s activities. It is outlined that the monitoring of financial risks is a set of information-analytical and control measures for managing financial risks, the content of which is to collect and process the necessary information about changes in relevant indicators, as well as providing results for the analysis of deviations and the assessment of their impact on the FIC. A number of methods and mathematical models for diagnosing the probability of bankruptcy of commercial organizations was considered. It is summarized that the simplest bankruptcy diagnostic method is a two-factor mathematical model, during the construction of which only two indicators are taken into account: the ratio of current liquidity and the specific weight of these funds in liabilities. Different ways of adapting ‘imported’ models (‘five-factor model’ by E. Altman, two-factor mathematical model) to domestic economic conditions are considered, and later Altman developed a similar, but more accurate model, which makes it possible to predict bankruptcy for the next five years with accuracy up to 70%. W. Beaver proposed a five-factor system for assessing the financial condition of an enterprise in order to diagnose bankruptcy. It consists of the following indicators: profitability of assets, specific weight of borrowed funds in liabilities, current liquidity ratio, share of net working capital in assets, Beaver ratio = (net profit + depreciation) / borrowed funds. It was determined that on the basis of statistical data processing, it is possible to apply a system of anti-crisis diagnostics techniques. Scientists equate diagnostics with a tool of anti-crisis policy.

Theoretical and methodological aspects of the application of marketing communications in the activities of educational organizations
Authors: Oleksiy Krasnorutskyy Oleksiy Krasnorutskyy , BLIUMSKA-DANKO Kseniia
Published: June 2023

In the constantly changing socio-economic conditions in educational institutions, there are many multifaceted problems that the institutions are not always able to solve on their own: financial and economic support, compliance of the list of specialties with the requirements of the labor market, selection of qualified teaching staff, recruitment of applicants, employment of graduates. All this requires educational organizations, regardless of their status, to work actively with the changing conditions of the external environment, consumer preferences and current directions in the field of education. Today, the acute problem is that for most educational organizations, marketing activity is still not a priority direction in the process of solving the problem of finding their consumers for the field of educational services. Contradictions and problems in the market of educational organizations can be eliminated by developing a special system for managing the promotion of services on the market. It is also necessary to take into account the market situation in the field of educational services. The existing rates of development of the educational services market, the emergence of new forms providing educational services led to increased competition, which, along with the rapidly changing conditions of the external environment, contributes to the transformation of forms and methods of promoting educational services, and it also caused changes in marketing approaches to the sale of educational services as a sought-after product in the service sector market. It was found out that such elements of marketing communications as advertising, public relations, exhibition activity, representation of the educational institution on the Internet are important. The communication system of an educational organization should be created so that the marketing department receives the information it needs to conduct its professional activities in a timely manner and without organizational complications, but it should not delegate its authorities, especially in terms of collecting and aggregating the necessary information, to other services of the university, which will inevitably lead to conflicts. Communications in the market of educational services mean a constant exchange of information between an educational organization and its external environment, which contributes to the maximum filling of classrooms with student due to full consideration of the modern requirements.

ABSTRACT

 At this time the use of bricks as a wall building material has begun to be widely used, this is because the manufacturing process is more efficient compared to making red bricks. Therefore, in this study, coconut shell waste will be used as additional material to test the compressive strength of bricks and determine the best percentage of coconut shell waste added in the brick mixture. The purpose of this study was to determine the effect of adding coconut shell waste on the strength of brick determination and to determine the best percentage of brick mixture with added shell waste. The research method used is an experimental method. The test results show that bricks with 3% and 4% coconut shell added materials are very influential on the compressive strength of bricks can provide a change of 6%. However, the addition of too many added materials causes a decrease in the compressive strength value of the bricks, because the added materials do not react with the brick mixture. The best percentage occurs in the addition of coconut shell fragments by 3% by producing an average brick compressive strength value of 11.63 Mpa.

Published: June 2023

Background: Integrating value-oriented perspectives into the principles and practices of software engineering is fundamental to ensure that software development activities address key stakeholders’ views and also balance short-and long-term goals. This is put forward in the discipline of value-based software engineering (VBSE)

Aim: This study aims to provide an overview of VBSE with respect to the research efforts that have been put into VBSE.

Method: We conducted a systematic mapping study to classify evidence on value definitions, studies’ quality, VBSE principles and practices, research topics, methods, types, contribution facets, and publication venues.

Results: From 143 studies we found that the term “value” has not been clearly defined in many studies. VB Requirements Engineering and VB Planning and Control were the two principles mostly investigated, whereas VB Risk Management and VB People Management were the least researched. Most studies showed very good reporting and relevance quality, acceptable credibility, but poor in rigour. Main research topic was Software Requirements and case study research was the method used the most. The majority of studies contribute towards methods and processes, while very few studies have proposed metrics and tools.

Conclusion: We highlighted the research gaps and implications for research and practice to support VBSE.

Legal Consequences of Violating the Obligations of Prospective Intern Notary: A Study of Legislation
Authors: Rosalinda Fitria , Aminah Aminah
Published: June 2023

This study examines and analyzes the legal consequences of violations of obligations committed by prospective intern Notaries based on Law Number 30 of 2004 and Law Number 2 of 2014. This study uses normative legal research with the statute and conceptual approaches. The collected legal material is then qualitatively analyzed to describe the problem and answer study purposes. The results show that the Article 16A of Law Number 2 of 2014 prescriptively indicates that prospective intern Notaries have attributive authority in doing authentic deeds. On the other hand, it reveals no additional articles providing sanctions if a prospective intern Notary violates this Article 16A of Law Number 2 of 2014. Despite these conditions, prospective intern Notaries ignoring their obligations are not exempt from legal consequences under Article 444 section (1) of Law Number 1 of 2023, Article 1365 of the Civil Code, and Article 12 point 3 of INI Regulation Number 19/PERKUM/INI/2019. Therefore, it is recommended that all stakeholders, including prospective intern Notary and Notary accepting intern, strictly adhere to the legal and regulatory framework governing internships. Further, the House of Representatives could consider for Amendment to Law Number 30 of 2004. In this case, legislation formation must provide more explicit provisions on the limitations and responsibilities of prospective intern Notaries and the consequences of violations. Clarifying these aspects could prevent misunderstandings, enhance the effectiveness of the internship program, and ultimately improve the overall quality and integrity of the Notary profession.
