Abstract

— The future trend in the field of management is the increasingly applied analytic data in every management decision, both for development and investment. Data submitted by companies are processed and evaluated by investors. However, the calculation pattern that is done is still based on financial analysis. This paper is intended to develop an analytic data framework that can be used by CEOs or investors in managing and valuing an industry. The research methodology used is using historical data in the Company's annual reports for the past five years and calculate it using SEM-PLS. This data is then entered into the analytic data framework and then being evaluated to get the essential resources or critical processes that have a strategic position or value in the industry. This research is using textile industry data. In the textile industry, it is found that the critical strategic resources are raw materials that significantly affect the Company's performance. This key finding is in line with the development of technology in raw material in the textile industry. This analysis method is intended to complement existing financial-based analyses that has been done for a long time. With this new analysis framework, the CEO and Investor will get a new perspective on the industry and take advantage of additional information from its result.

Abstract

Alignment and agility are essential supply chain capabilities required to maintain and enhance performance, particularly in the current era of disruption. The research aimed to examine the impact of blockchain capabilities on supply chain resilience and company performance using quantitative and cross-sectional survey methods. Logistics service providers (LSP) were selected as the units of analysis, and individuals such as logisticians in Indonesia and Switzerland served as units of observation. Data were collected through an electronic questionnaire (Google Forms) using a quota sampling technique and analyzed using Smart-PLS software. The sample size included 60 respondents, comprising 45 and 15 from Indonesia and Switzerland based on the 10-times rule. The results show that supply chain resilience partially and fully mediated the impact of blockchain capabilities (supply chain alignment and agility) on LSPPerformance. LSP could also enhance performance and resilience by implementing blockchain technology to enhance supply chain alignment and agility. In theoretical terms, the results have implications contributing to dynamic capability theory. In practical applications, the research serves as valuable insights for government authorities and IT consultants when formulating effective plans and strategies to analyze the adoption of blockchain technology among LSP. Additionally, directors and owners of these companies are persuaded that blockchain has the potential to create and enhance supply chain capabilities, as well as increasing competitive advantage.

Abstract

The transition from fossil fuel vehicles to electric vehicles (EVs) in Indonesia is critical for reducing emissions and achieving sustainable transportation. Despite government support through policies like Presidential Regulation No. 55/2019, EV adoption remains low due to challenges such as high costs, limited infrastructure, and consumer hesitancy. This study investigates the factors influencing switching intentions to EVs in Indonesia, employing the push-pull-mooring (PPM) framework to analyze environmental concern, cost concern, perceived usefulness, financial incentives, and infrastructure readiness. Using a mixed-methods approach, the research collected data from 136 respondents in Greater Jakarta through structured questionnaires, analyzed via Partial Least Squares Structural Equation Modeling (PLS-SEM). Findings revealed that environmental concern, cost concern, and perceived usefulness significantly positively influence switching intentions, while financial incentives showed limited impact. Surprisingly, infrastructure readiness did not significantly moderate these relationships, suggesting other barriers may hinder adoption. The study contributes theoretically by adapting the PPM model to EV adoption, identifying cost concern as a push factor and financial incentives as a pull factor. Practically, it highlights the need for targeted policies, such as enhanced public awareness campaigns and improved charging infrastructure, to accelerate EV uptake. Future research should explore additional moderators like socio-cultural influences and adopt longitudinal designs to track evolving consumer behavior. This research provides valuable insights for policymakers, industry stakeholders, and researchers aiming to foster EV adoption in emerging markets like Indonesia.

Abstract

In an increasingly competitive and globalized business environment, procurement has evolved from a transactional function to a strategic driver of organizational efficiency and competitive advantage. The quality and service performance of suppliers are critical, yet their pathway to influencing overall procurement success requires further empirical exploration. This research aims to analyze the influence of supplier quality and supplier services on procurement competitive advantages and their impact on procurement performance. In an increasingly competitive business environment, procurement functions play a strategic role in supporting operational efficiency and a company’s competitive edge. This research employs a quantitative approach, collecting data through surveys of procurement managers across various industry sectors. Structural Equation Modeling (SEM) is used for data analysis. The results indicate that both supplier quality and supplier services have a positive and significant impact on procurement competitive advantages. Furthermore, procurement competitive advantages significantly enhance procurement performance, particularly in terms of cost efficiency, responsiveness, and internal stakeholder satisfaction. These findings highlight the importance of building strategic relationships with high-quality and responsive suppliers to achieve superior procurement performance.
