Environment and Benchmarking: Industry 4.0 Sustainable Work Readiness Framework

This paper presents a sustainable work readiness framework for engineering students, incorporating core skills, personal skills, and self-efficacy as mediating variables. The study aims to investigate the impact of core skills and personal skills on engineering students’ work readiness, as well as the mediating influence of self-efficacy on this relationship. The researchers designed and tested a work readiness framework with three focal points: skills, personal skills, and self-efficacy, and their influence on engineering students’ work readiness. The findings indicate that core skills, personal skills, and self-efficacy positively and significantly influence engineering students’ work readiness. Self-efficacy can be explained by the core skills and personal skills variables at 87.8%, while the work readiness variable can be explained by core skills, personal skills, and self-efficacy at 85.4%. This study contributes to the existing literature by proposing a sustainable work readiness framework and measurement instrument that link core skills, personal skills, and self-efficacy as mediating variables influencing work readiness. The results are beneficial not only to Universiti Teknologi PETRONAS, Malaysia, as they directly reflect the work readiness of UTP’s final-year undergraduate engineering students but also to individuals, universities, teaching staff, organizations, human resource specialists, and public administrators. They can use these findings to enhance the development of individual work readiness skills and increase the work readiness of students in their respective universities. The novelty of this study lies in proposing a sustainable work readiness framework tailored to equip engineering students with the skills required and acquired in Industry 4.0.

Cloud Computing Based Computing System for Women's Higher Education in Isolated Areas

A new chapter in information technology is opened by cloud computing in computer science and engineering education. Understanding the importance of using cloud computing (CC) in institutions of higher learning is the aim of this research. This analysis shows some of the benefits that cloud computing can provide to higher education, assesses some of the most significant challenges that academics may encounter as a result of its implementation, and suggests some initial steps toward its adoption while mitigating the risks associated. Enterprise apps have migrated in large numbers to the cloud in recent years. One of the challenges posed by cloud applications is the challenge of allocating resources to the application to ensure a service level along dimensions like performance, availability, and dependability. To do this, a system based on the infrastructure of governmental bodies, non-governmental organisations (NGOs), academic institutions, and other providers of social services has been established. The results of this analysis demonstrate that it is possible to use a few variables, including administrative bodies and governments, internal stakeholders, cloud suppliers, firm attributes, socio-political changes, IT framework, and others, to understand how CC adoption methodologies are used in higher education institutions. In addition to providing insight into how cloud providers, advisers, governments, and academics see various market demands and how they respond to these expectations while expanding services provided by CC in higher education institutions, this analysis opens opportunities for future research. The implications for practice can aid decision-makers in utilizing CC services legally

Coal Energy and Macroeconomic Conditions

This paper assesses the effect of coal energy production volume, exchange rate, inflation and gross domestic product on the volume of Indonesia's coal energy exports in 1998-2019. Based on an Autoregressive Distributed Lag (ARDL) approach, in the short run, we find that the coal energy production volume, exchange rate, and gross domestic product has a negative relationship to Indonesia's coal energy exports. However, on the other hand, inflation has a positive relationship to Indonesia's coal energy exports. In the long run, we also find that the coal energy production volume, inflation, and gross domestic product has a positive relationship to Indonesia's coal energy exports. Besides, the exchange rate has a negative relationship to Indonesia's coal energy exports.Keywords: Coal Energy, Exchange Rate, Inflation, Gross Domestic Product, Autoregressive Distributed LagJEL Classifications: E2, E6, Q4, Q2DOI: https://doi.org/10.32479/ijeep.11214</div

World Oil Prices and Exchange Rates on Islamic Banking Risks

Islamic banking risks are influenced by many factors, facing internal and external banking risks. In this study, the internal banking risks are represented by Credit risk as measured by Non-Performing Financing (NPF) and liquidity risks as measured by Financing to Deposit Ratio (FDR). At the same time, world oil prices and exchange rates represent the external banking risks. World oil price data is obtained from OPEC Price, and exchange rate data is obtained from the Pacific Exchange Rate Service. While the data from NPF and FDR is obtained from BI Statistics of Sharia Banking. The results of this study found that world oil prices have a significant effect on credit risk and liquidity risk in Islamic banking. In contrast, the exchange rate only has a significant effect on credit risk in Islamic banking
