Abstract

This study aims to analyze the contribution of the diversity of biota in the waters of Toba Lake to the richness of Indonesia's biota. Research is needed to analyze the diversity of Lake Toba water biota. In order to achieve this goal, data and information collected regarding the contribution of the diversity of Lake Toba waters to the richness of Indonesia's biota is used. Verification of the data and information obtained was carried out through literature study, document analysis, interviews and filling out questionnaires. The results showed that in the waters of the lake there are endemic fish species whose existence is currently almost extinct, namely Batak fish or "ihan" (Neolissochillus thienemanni) consisting of two species, namely: Lissochilus sumatranus and Labeobarbus soro. There are various types of aquatic plants such as various types of algae and water hyacinth. Apart from that, there are also various species of molluscs such as freshwater snails and clams as well as other aquatic animals such as frogs and eels. The aquatic biota of Lake Toba has an important role in maintaining the balance of the ecosystem and providing resources for the people around the lake and contributing to Indonesia's Biota Wealth.

Abstract

This study examines the influence of entrepreneurial orientation, innovation capability, and risk-taking on business performance among small and medium enterprises (SMEs). Grounded in the Resource-Based View and dynamic capabilities theory, the research investigates how strategic orientation and organizational capabilities contribute to firm performance in competitive and uncertain business environments. A quantitative explanatory approach was employed using survey data collected from 210 SME owners and managers. Data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to assess both measurement and structural models. The findings reveal that entrepreneurial orientation, innovation capability, and risk-taking each have a positive and significant effect on business performance. Among these variables, innovation capability emerged as the strongest predictor, indicating that the ability to develop and implement new ideas, technologies, and processes plays a crucial role in enhancing firm outcomes. Entrepreneurial orientation significantly contributes by fostering proactive and innovative strategic behavior, while risk-taking supports performance through calculated engagement in uncertain opportunities. Collectively, the three variables explain a substantial proportion of variance in business performance, demonstrating the importance of integrating entrepreneurial mindset, innovation processes, and strategic risk behavior. The study provides theoretical contributions by offering an integrated framework of strategic drivers of performance and practical implications for SME managers seeking sustainable competitive advantage.

Abstract

The increasing complexity of business environments driven by digital transformation and sustainability challenges has heightened the importance of understanding how management control systems and alliance strategies jointly influence innovation capacity and business performance. Therefore, this study aims to conduct a systematic literature review and synthesize recent research on the interrelationship between management control systems, alliance strategies, innovation, and firm performance to identify emerging themes, research gaps, and theoretical contributions. Using the PRISMA approach, 22 peer-reviewed articles published between 2020 and 2025 were selected from the Scopus, Web of Science, and DOAJ databases and analyzed for conceptual and methodological insights. The findings reveal that management control systems and alliance strategies play a significant role in enhancing innovation capability and improving business performance, while digitalization and sustainability emerge as crucial contextual determinants. However, existing studies have yet to fully explain how these constructs dynamically interact within technology-driven and uncertain environments to support sustainable innovation. Based on this synthesis, the study proposes a conceptual model integrating management control systems and alliance strategies to achieve superior innovation and performance outcomes and suggests that future research employ longitudinal and cross-industry designs to validate and extend the proposed framework.
