Abstract

Agriculture has been an inherent part of human civilization for centuries. Therefore, this study aims to analyze the relationship between agricultural production and agricultural community income. The pattern of their relationship followed the dynamics of the Lotka-Volterra model. Two of the six critical phenomena that might occur: first, if the farmer's crop were abundant, the farmers' income would increase rapidly; second, if the farmers' yields decreased, the farmer's income would automatically decrease. Low and unstable farmer income could lead to poor productivity and low economic growth. Thus, monitoring and early warning were essential to effectively prevent possible negative impacts on agricultural product production, consumption, and changes in market prices. Sustainable agricultural systems included maintenance or enhancement of environmental natural resources, food supply, and social welfare. In brief, good agricultural management could maintain the balance of the ecosystem, contribute to the economy continuously, and increase agrarian communities' economic resilience. Keywords: agrarian community; ecosystem; harvest cycle; income; Lotka-Volterra

Abstract

Competition in the business world is something that cannot be avoided, for example competition in the banking sector. In this sector, competition has the potential to encourage the business world to be more competitive, and also improve the efficiency and health of banks. The aim of this research is to analyze the competition that occurs between bank BNI and Mandiri using the Lotka-Volterra competition model approach. The results of this research indicate that the type of competition between bank BNI and Mandiri is the predatory-prey, where BNI acts as a prey, while Mandiri acts as a predator. In addition, the results of future net income forecasting show that BNI's net income tends to decline over the next ten years, and after that it will be stable. On the other hand, Mandiri's net income will increase over the next three years, with maximum net income obtained in 2025, and after that it will be stable. Therefore, both of them must adopt a policy to overcome net income which is likely to experience stagnation in the future. Keywords: bank, competition, Lotka-Volterra, net income, predatory, stable

Abstract

Profitability and liquidity are among the critical issues that must be studied and considered by the management of every organisation as their foremost task. This research aims to analyse the bidirectional dynamics of profitability ratios and liquidity ratios over time. This research also aims to present forecasted values of profitability and liquidity for the next five years. The data used in this study are obtained from the food industry company’s annual reports for the period 2011-2022. This research adopts a predator-prey model containing a pair of non-linear differential equations to describe the interaction between two species. The results show that the predator-prey model can explain the bidirectional dynamics of profitability ratios and liquidity ratios with high accuracy. Besides, this study indicates that the type of relationship between profitability and liquidity is predator-prey. The forecasting results show that for 2023-2027, both profitability and liquidity tend to decrease. Based on the data, the company’s profitability and liquidity dynamics periodically fluctuate over time. This fluctuation indicates a positive sign for company’s profitability and liquidity are in good condition. In the future, company has to take preventive measures to continue stabilising its profitability and liquidity.

Abstract

Research Originality: Competition in the banking sector is unavoidable.  Such competition is present among state-owned banks in Indonesia. In contrast to the previous studies that did not include the competition type and its stability, this study includes the competition type and its stability in the estimation.Research Objectives: This study aims to discover the competition type and its stability, and to forecast the market share among the four state-owned banks.Research Methods: Using market share data of assets published annually by each of the banks from 2010 to 2023, the study employs the Lotka-Volterra model approach to analyze the competition type and its stability that occur among the four state-owned banks.Empirical Results: The study discovers that the competition types of the four state-owned banks vary. There have been three competition types among the four state-owned banks: mutualism, predator-prey and pure competition. Besides, the stability property of the four state-owned banks tended to be unstable. By looking at the gains of market share for assets, only Mandiri’s market share gains will increase in the 2024-2028 period. As a result, the total market share gains for the four state-owned banks declined sequentially.Implications:This research holds significance for four state-owned banks in Indonesia as it provides valuable insights into considering the three competition types (mutualism, pure competition and predator-prey) as the primary key to achieving a significant market share value.JEL Classification: C61, D41, E17, G21How to Cite:Jamal, S.
