Testing the Role of Socioeconomic Levels and Government Policies in Spreading Coronavirus Disease 2019 (COVID-19) in ASEAN

/in /by

Although there has been an enormous scientific attempt to understand the transmission of COVID‐19, there are many knowledge gaps yet to be filled. This study aims to investigate the role of socioeconomic level and government response in the spread of COVID-19. The socioeconomic level is represented by gross domestic product, population density, and multidimensional poverty index. Meanwhile, government policies are characterized by a stringency index, and the incidence rate represents the spread of COVID. Using a sample of 10 ASEAN countries, from March 28, 2020, to July 30, 2021, the results show a positive relationship between socioeconomic level and the incidence rate of COVID-19 in communities, meaning socioeconomic factors are the determinant of the incidence rate of COVID-19. In addition, there is a significant negative relationship between the stringency index and the incidence rate, revealing that the more stringent policy was, the less COVID spread.

The Role of Profitability in Moderating the Influence of Liquidity and Leverage on Audit Opinion

/in /by

The auditor issued an audit opinion to determine the risk of uncertainty regarding the condition of the company to continue operating where COVID-19 is spreading rapidly. This research aims to look at the influence of liquidity and leverage on audit opinion in the consumer goods sector listed on the Indonesia Stock Exchange in 2020, with profitability as a moderation variable. The research model uses a causal-comparative design and binary logistic regression analysis with secondary data types. 188 consumer goods sector companies listed on the Indonesia Stock Exchange, in 2020, met the criteria for being the research sample. The results of the study showed that liquidity and leverage simultaneously affect audit opinion. Partially, liquidity has no influence on audit opinion, while leverage partially affects audit opinion. Profitability as moderation is able to strengthen the influence of liquidity on opinions but is not able to moderate the influence of leverage on audit opinions. The limitation in this study is that it only selects the company’s internal factors. Further researchers are expected to consider other free variables such as auditor turnover, and opinions submitted by auditors in the previous period, as well as using other sectors such as the real estate property sector. The leverage factor can be used as reference data for auditors to see how the company is able to maintain the condition of the company to avoid bankruptcy in the pandemic.

Solving A ML Problem Using The Grossone

/in /by

Machine learning (ML) has grown at a remarkable rate, becoming one of the most popular research directions. It is widely applied in various fields, such as machine translation, speech recognition, image recognition, recommendation system, etc. Optimization  problems lie at the heart of most machine learning approaches. So, the essence of most ML algorithms is to build an optimization model and learn the parameters in the objective function from the given data. A series of effective optimization methods were put forward, in order to promote the development of ML. They have improved the performance and efficiency of ML methods. The aim of this paper is to show that, among many other fields, the grossone may be used successfully in the ML. The grossone, the infinite unit of measure, has been proposed by Professor Y. Sergeyev in a number of noticeable works, as the number of elements of the set, N, of natural numbers. It is expressed by the numeral . This new computational methodology would allow one to work with infinite and infinitesimal quantities in the ―same way‖ as that working with finite numbers  More details about it are given in Section 4. We analyze the SVM from the viewpoint of mathematical programming, solving a numerical example using the grossone. The Iris dataset was chosen for the implementation of the support vector method. This is a wellknown set of data used in the area of ML.

Tapping the New Source of Growth: New Marketing Strategy for a Heavy Equipment Distributor in the Nickel-Mining Sector

/in /by

Indonesia which owns 23% of the world’s nickel reserves, is in the early phase of the nickel sector development, which affects the heavy equipment industry to support operations. PT Kaizen Distributor, Tbk is a seller of an Articulated Dump Truck (ADT) and the sole distributor of the Kaizen brand in Indonesia. To date, the corporate has focused only on sales to the coal and gold mining sector and is yet to conduct nickel-mining market penetration to the fullest. This is indicated by a decrease in the corporate nickel sub-sector contribution from 26% to 16% and instability of unit sales. While the current ADT competition is very competitive, therefore, the purpose of this research is to formulate a new marketing strategy to focus on the nickel-mining segment. The qualitative methods were used by carrying out observations, in-depth interviews, and utilizing supporting data from internal and external corporate reports. SWOT Analysis is a generic framework used for business environment analysis. The Positioning Maps and the Existing 4Ps Marketing Mix are used to assess the corporate’s positioning and strategies. As the research result, the corporate needs to develop strategies based on the relationship between the corporate’s internal-external environment factors using TOWS and make changes in Positioning regarding more product variety and more attractive promotion campaigns. This repositioning is supported by the development of the Existing 4Ps Marketing Mix, such as by improving the features of existing products and proposing a larger capacity type, considering pricing strategies, increasing supply allocation, widening market area coverage, attractive maintenance packages, flexible financing, and product bundling package offers. Also, the addition of other 3Ps as a form of improvement is by evaluating salesperson’s competency in entering new markets, increasing the efficiency of customer surveys, and adding new product support points.
