Maintenance and industrial relations are two crucial aspects in human resource management that are interrelated and play an important role in maintaining the continuity and success of the organization. Effective maintenance not only maintains the quality of employee performance but also contributes to the creation of harmonious industrial relations. Good industrial relations, in turn, create a conducive work environment, increase productivity, and reduce the potential for conflict in the workplace. The purpose of this study is to dig deeper into the understanding of maintenance and industrial relations. This study uses qualitative and quantitative methods. Data collection techniques are carried out through a review of several journals that have been searched, which are related to the importance of maintenance and industrial relations. From the data that has been successfully collected, maintenance of industrial relations in the entire process of human resource management focuses on the belief that good and harmonious relations between employers and workers in the organization are very important to be fostered and maintained for the benefit of all parties involved. Failure to maintain harmonious relations can cause losses for many parties, especially employers and workers involved. Effective maintenance and good industrial relations play an important role in the success and survival of the company. Therefore, maintenance is a vital element in today's business world and needs to be managed properly.

Taxes are the main fiscal instrument in modern states, serving various strategic functions such as budgeting, regulation, stability, and income redistribution. Taxes are not only a source of state revenue but also a tool to encourage economic growth and the equitable distribution of welfare. In the context of Islamic economics, taxes have a different position but are not fundamentally contradictory. Islam recognizes the concept of levies such as zakat, kharaj, jizyah, and ushr, which have similar objectives to modern taxes, namely for the welfare and social justice. This research uses a qualitative method with a literature study approach to analyze the alignment between the function of taxes in modern states and the principles of Islamic economics. Data were collected through a literature review from relevant academic sources. The research results show that although there are differences in mechanisms and characteristics, there is a common ground in the main goal, which is the welfare of society. Taxes can be accepted in Islamic economics as long as they are collected fairly, transparently, proportionally, and used for the public good. Further analysis indicates that the principles of maqashid sharia can serve as an important reference in modern tax reform to better align with Islamic values. The conclusion of this study emphasizes the importance of integrating Islamic economic principles into the tax system to create social justice, fiscal efficiency, and sustainable development. This research is expected to provide theoretical and practical contributions to the development of a tax system based on Sharia values in the contemporary era.

The main issue faced by BSI Farm is the suboptimal quality control at each stage of hydroponic kale production, resulting in inconsistent product quality. This study aims to analyze the quality of hydroponic kale products at BSI Farm using the input-process-output (IPO) approach. The analysis covers all stages of production, from the selection of superior seeds, nutrient and water management, cultivation using the NFT (Nutrient Film Technique) system, to harvesting and packaging. The results show that the implementation of strict quality control at each stage successfully produces fresh, clean, pesticide-free kale that meets modern market standards. Production waste is managed through a grading system and utilized as animal feed to minimize environmental impact. The main challenges include pest attacks, plant diseases, and inconsistent harvests due to a lack of standardized procedures. However, these can be addressed through regular monitoring, appropriate use of pesticides and fungicides, and consistent implementation of cultivation SOPs.

This study discusses the ethics of Muslim entrepreneurship in facing the challenges of modern capitalism. Capitalism, characterized by profit orientation, individualism, and materialism, often clashes with the moral and spiritual principles of Islam.

This research uses a qualitative approach with a library research method to explore practical strategies that Muslim entrepreneurs can apply to remain ethical and compliant with Islamic law. The findings show that Islamic ethical principles serve not only as moral guidance but also as a competitive strength in capitalist economic systems.

QRIS (Quick Response Code Indonesian Standard) is a national digital payment innovation launched by Bank Indonesia to strengthen Indonesia’s digital and economic sovereignty. By integrating various payment platforms into a single QR code standard, QRIS simplifies domestic transactions—especially for Micro, Small, and Medium Enterprises (MSMEs)—while reinforcing state control over financial infrastructure and data flows. This policy reduces reliance on international payment networks such as Visa and Mastercard, which previously dominated digital transactions and stored data abroad. On a global scale, QRIS functions as a tool of digital economic diplomacy through cross-border payment initiatives like ASEAN Pay, enabling Indonesia to expand its influence in the global digital payment ecosystem. However, the United States has criticized QRIS, arguing that it restricts access for foreign companies and poses a barrier to trade. In response, the Indonesian government asserts that QRIS is designed to protect national interests while promoting fair international collaboration. This study employs a normative juridical and descriptive qualitative approach to analyze QRIS-related regulations, its impact on digital sovereignty, and its implications for international trade relations. Secondary data is sourced from literature studies and official documents. The findings reveal that QRIS plays a vital role in accelerating MSME digital transformation, enhancing financial inclusion, and strengthening Indonesia’s bargaining position in global digital finance. Ultimately, QRIS stands not only as a transaction tool but also as a strategic symbol of Indonesia’s digital independence and competitiveness in the international financial landscape.

This study examines the market mechanism from the perspective of Islamic economics as a response to conventional economic systems that tend to emphasize either free-market principles or full government intervention. In Islam, the market mechanism is governed by principles of justice, transparency, and balance among the interests of individuals, the state, and society. This research highlights the thoughts of classical Islamic scholars such as Abu Yusuf, Ibn Taymiyyah, Al-Ghazali, and Ibn Khaldun, who had already elaborated on the concepts of markets, pricing, supply and demand, and ethical conduct in transactions long before Western economists developed similar ideas. Using a qualitative approach and literature review, this article analyzes various market distortions such as ihtikar (hoarding), tadlis (fraud), riba (usury), and gharar (uncertainty), as well as the role of government in limited intervention to maintain balance and fairness. The findings show that the Islamic market mechanism is not solely focused on economic efficiency, but is also deeply rooted in moral and spiritual values.
