separating and shredding organic and inorganic waste. This study aims to analyze the process of shredding household waste using the Computational Fluid Dynamics–Discrete Element Method (CFD-DEM) and determine the optimal operational parameters based on variations in rotor speed. The research method uses numerical simulation with SolidWorks 2024 software for geometric modeling and Ansys Rocky 2023 R1 for CFD-DEM simulation. The rotor speed variations used are 1000 RPM, 2500 RPM, and 4000 RPM with a mass flow rate of 4 tons/hour and a simulation duration of 2 seconds. The parameters analyzed included particle mass flow rate, shredding characteristics, and power consumption. The simulation results showed that a speed of 1000 RPM produced the most optimal performance with a maximum capacity of ±4 tons/hour and a stable shredding response compared to other variations. At 2500 RPM, there were high fluctuations with low capacity (±0.6 tons/hour), while at 4000 RPM, the capacity was moderate (±1.1 tons/hour) but still did not exceed the performance of 1000 RPM. Based on these results, it can be concluded that a rotor speed parameter of 1000 RPM is the most effective condition for improving the grinding efficiency and production capacity of a hammer mill-type Depackaging machine based on CFD-DEM simulation.

The adoption of holocratic leadership systems has become a crucial strategy for startups navigating market volatility, which demands organizational agility through the elimination of traditional hierarchies. This study aims to analyze the transformation of the Human Resource (HR) department's role within holocratic systems and its impact on HR efficiency in startup environments. Employing an integrative literature review approach, this research synthesizes various findings from reputable global and national journals published within the last five years to map the shifts in managerial functions. The results indicate that in structures devoid of conventional managers, the HR role transforms from a controlling authority into a system architect and governance facilitator that maintains compliance with the organizational constitution. HR efficiency is achieved through clear authority distribution within dynamic roles, transparent peer-to-peer feedback mechanisms, and the removal of slow bureaucratic coordination costs. The contribution of this research lies in the formulation of the "HR-as-a-Platform" conceptual model, which shifts the focus of management practices from personal supervision to systemic infrastructure optimization. The practical implications provide a guide for startup founders to re-engineer HR functions to support individual autonomy without sacrificing operational stability. This study confirms that the success of non-hierarchical organizations relies heavily on the integration of radical autonomy and robust digital protocols facilitated by the newly defined HR function.

Micro, small, and medium enterprises (MSMEs) constitute a pivotal pillar of local economic resilience in Bandar Lampung, particularly in the fashion, salon and beauty, and professional service sectors. Notwithstanding their considerable growth potential, many MSMEs continue to encounter structural constraints that impede business expansion, most notably limited entrepreneurial capability, restricted access to capital, and the suboptimal utilization of digital marketing. Against this backdrop, the present study aims to examine the partial and simultaneous effects of entrepreneurship training, capital access, and digital marketing strategy on MSME business expansion. This research employed a quantitative explanatory design with a cross-sectional approach. Data were collected from 100 MSME owners selected through purposive sampling from a population of 2,785 enterprises, and were analyzed using multiple linear regression with SPSS. The findings reveal that entrepreneurship training does not exert a statistically significant effect on business expansion (B = 0.000; p = 0.998), indicating that training, in isolation, has not yet been effectively translated into concrete growth-oriented business practices. By contrast, access to capital has a positive and significant effect (B = 0.263; p = 0.001), demonstrating that financial accessibility enhances operational scale and market development. More importantly, digital marketing strategy emerges as the most influential determinant of business expansion (B = 0.593; p < 0.001), confirming that digital platform utilization substantially strengthens market reach, customer engagement, and business competitiveness. Simultaneously, the three variables significantly affect MSME expansion (F = 34.061; p < 0.001), with an explanatory power of 51.6%. It can therefore be concluded that MSME expansion is primarily driven by the synergy of financial accessibility and digital market adaptation, while entrepreneurship training becomes meaningful only when effectively operationalized within business practice.

Health-related SMEs in Indonesia have significant opportunities to enter international markets, but many businesses still face limitations in digital capabilities, innovation, and readiness for external markets. This study aims to examine the influence of digital transformation on the success of health-related SMEs in going international, both directly and through business innovation as a mediator. The study employs a quantitative approach using a cross-sectional survey design involving 200 owners or key managers of SMEs in East Java, selected via purposive sampling. Data were analysed using Structural Equation Modelling-Partial Least Squares (SEM-PLS). The results indicate that digital transformation has a positive influence on business innovation and the success of going international. Business innovation also has a positive effect on internationalisation success and mediates the relationship between digital transformation and external market success. These findings confirm that digitalisation should not merely be understood as an operational tool, but as a strategic capability that must be integrated with product, process, marketing, and business model innovation. The research implications emphasise the importance of strengthening digital capabilities and business innovation to enhance the global competitiveness of Indonesian health-related SMEs.

The steering gear is a vital component in ship operations, functioning to control the ship’s direction accurately. The reliability of this system highly depends on the performance of the hydraulic system, where the mechanical seal plays a key role in maintaining system pressure and preventing oil leakage. This study aims to identify the main factors causing mechanical seal damage and analyze its impact on the performance efficiency of the steering gear AHTS Logindo Stamina. Qualitative data were obtained through participatory observation and in-depth interviews with the second engineer. Meanwhile, quantitative data were gathered by measuring technical parameters such as oil pressure, operating temperature, and rudder movement time, which were then compared with SOLAS standards. This damage results in oil leakage through the mechanical seal gap, abnormal noise in the hydraulic system, and a significant decrease in working pressure of -25,86%.

This study recommends preventive maintenance through oil quality monitoring, environmental condition control in the steering gear room, and periodic mechanical seal replacement in accordance with operational standards to maintaining optimal steering system performance.

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in supporting local and national economic development, particularly through employment generation and income distribution. Seasonal religious events such as Ramadan significantly influence consumption patterns and market dynamics, creating both opportunities and challenges for MSMEs. This study aims to analyze the implementation of the “Seri Ramadhan” phenomenon within the strategic management practices of MSMEs in Martapura, focusing on the periods before and after Ramadan. The research employed a qualitative descriptive approach with field study methods. Data were collected through in-depth interviews, direct observation, and documentation involving selected MSME actors in the culinary, fashion, and retail sectors. The findings indicate that prior to Ramadan, MSMEs emphasize strategic planning through product innovation, stock preparation, promotional intensification, and operational adjustments. After Ramadan, they conduct performance evaluations, inventory control, and strategic realignment to maintain business sustainability. The study highlights that Ramadan is not merely a short-term sales opportunity but also a strategic momentum integrated into broader business planning cycles. The implications suggest that adaptive and cyclical strategic management enhances MSME resilience and competitive advantage in seasonal markets.

The development of information technology has become a primary pillar in enhancing corporate operational efficiency, where rapid and accurate data integration significantly determines business competitiveness. Case study in PT Gawi Anjung Bersama (GAB) revealed that the company is facing operational constraints because the management of delivery orders and invoices still relies on conventional office applications such as Microsoft Excel and Word. This procedure causes hurdles in data sharing among staff and results in low information security due to the absence of integrated access control settings. This research aims to design and develop the Gawi Anjung Bersama Information System (SIGAB), a web-based system implementing the CodeIgniter framework. The system is developed using Waterfall model, encompassing stages from analysis, design, and implementation to testing. The research flow starts with problem identification, primary and secondary data collection, and functional and non-functional requirements analysis. The system is designed using Unified Modeling Language (UML) modeling, specifically Use Case and Class Diagrams, as well as Entity Relationship Diagrams (ERD) for the database. The system interface is designed as wireframes on Figma web. This system separates access rights into three main actors namely owner, administrator, and staff, to ensure data security. Blackbox testing results, conducted after the system was hosted, indicate that all functional features operate as intended. The implementation of SIGAB is expected to optimize the management of delivery orders and invoices at PT GAB.

This research is motivated by the escalating prevalence of illegal online lending practices in Indonesia, which generate a multitude of legal problems, particularly those concerning the validity of loan agreements and debt collection practices. The simplicity of access through smartphone applications, rapid processing times often approved within minutes and minimal administrative requirements have rendered these services immensely popular among the public. However, this accessibility also paves the way for unlicensed providers to operate unchecked, preying on desperate borrowers. The study aims to analyze the legal validity of illegal online loan agreements pursuant to the Indonesian Civil Code (KUHPerdata) and regulations issued by the Financial Services Authority (Otoritas Jasa Keuangan, OJK). Additionally, it examines the legal position of debt collection from a civil law perspective. A normative juridical method is employed, utilizing statutory and conceptual approaches, with qualitative analysis of the data. The results demonstrate that illegal online loan agreements fail to fulfill the requirements for a valid contract, especially regarding the legal capacity of the parties and lawful cause, categorizing them as null and void by operation of law. Nevertheless, in practice, unlicensed providers continue debt collection efforts, frequently employing methods that violate the law, such as harassment and intimidation. This reveals a significant gap between legal norms and field implementation. The implications emphasize the critical need for robust law enforcement, enhanced consumer protection mechanisms, and stricter oversight of fintech lenders to establish legal certainty and justice for society.

Food and beverage companies must maintain a robust capital structure to compete effectively amidst the intense pressures of globalization and achieve their strategic objectives. This study aims to examine the impact of profitability, asset structure, company size, and solvency on the capital structure of food and beverage firms listed on the Indonesia Stock Exchange (IDX) and included in the LQ45 index. This study uses an explanatory method with purposive sampling technique, where samples are determined based on companies that have completed financial reports during the research period and are indexed in LQ45. Data analysis was performed using t-tests and F-tests. The results show that profitability (ROA), asset structure, and company size (Ln Total Assets) do not have a significant partial effect on capital structure (DER), meaning that these three factors do not directly influence companies' decisions on the use of debt for financing. However, solvency (DAR) was found to have a significant effect on capital structure, indicating that a company's ability to meet its long-term obligations plays an important role in determining the level of debt used for operational financing. Simultaneously, the four independent variables had a significant effect on capital structure, meaning that all variables together contributed to influencing food and beverage companies' decisions in determining their financing strategies.

ABSTRACT Hospitals can be established by the Central Government, Regional Government, or the Community. Hospital management organized by the Government can apply the financial management pattern of BLU or BLUD. Hospital independence can be achieved through healthy business processes. The dual role of hospitals as public services and business entities. The commercial health sector is increasingly closely linked to the global health industry. Collaboration between BLU hospitals and private business entities is often manifested in KSO contracts. KSO contracts must contain legal principles (rechtbeginselen) which serve as basic norms and guidelines in the formation or creation of legal regulations. The principle of personality in KSO contracts is important to ensure the parties' performance is balanced. This study uses a normative or doctrinal legal research methodology by examining primary legal sources in the form of KSO contracts between BLU hospitals and private business entities, the Civil Code, and other material laws. A study was also conducted on secondary legal sources in the form of legal materials consisting of books or legal journals regarding legal principles, the views of legal doctrines, and the results of legal research. Keywords : Principle of Personality, Public Service Agency, Operational Cooperation Contract.

The advancement of financial technology has resulted in the creation of electronic wallets that serve not only as payment instruments but also as platforms for electronic transactions and digital loan services. This situation engenders a conflict between the implementation and the prevailing regulation, specifically Bank Indonesia Regulation Number 18/40/PBI/2016 regarding Payment Transaction Processing, which raises concerns about legal certainty and user protection, particularly in relation to the delineation of supervisory authority between Bank Indonesia and the Financial Services Authority. This research aims to elucidate the regulation of electronic wallets in terms of legal clarity, legal protection, and oversight by the Financial Services Authority and Bank Indonesia concerning the adoption of electronic wallets. This study employs a normative legal methodology. Data is derived from secondary sources, encompassing primary, secondary, and tertiary legal literature. This study employs both a legislative and a conceptual methodology. The research findings suggest that the regulation of electronic wallets, as per Bank Indonesia Regulation, has not entirely met user requirements. Bank Indonesia Regulation Number 18/40/PBI/2016, on the Implementation of Payment Transaction Processing, does not explicitly address legal certainty and legal protection for users who deposit funds or utilise digital loan services on electronic wallets. This situation establishes a disparity between regulatory implementation and governing rules, which may result in insufficient oversight of electronic wallet operations and a discord of authority between Bank Indonesia and the Financial Services Authority regarding the supervision of financial transactions in Indonesia.

This study aims to analyze the optimization of regional expenditure in the education sector of Surabaya City for the 2025 fiscal year in supporting regional development. The research uses a descriptive qualitative approach through observation, interviews, and documentation studies conducted at the Surabaya City Education Office. Data were obtained from relevant stakeholders involved in education budget management and supported by official documents related to policies and the implementation of education programs. The results show that the management of education expenditure has been aligned with the Regional Medium-Term Development Plan (RPJMD) and applies the money follow program principle, which prioritizes programs based on community needs and development priorities. Programs such as Regional School Operational Assistance (BOPDA), educational assistance for students, school infrastructure development, and community-based learning innovations have contributed to expanding access to education, improving the equity of educational services, and reducing dropout rates. In addition, the use of monitoring systems, periodic evaluation, and the involvement of multiple stakeholders in supervision has strengthened transparency and accountability in budget management. However, several challenges remain, including limited implementation time, procurement constraints, and economic conditions such as inflation. Overall, education expenditure in Surabaya has been managed relatively well in terms of effectiveness, efficiency, and accountability while still requiring continuous improvement

The global rise in life expectancy toward the 100-year threshold has accelerated the emergence of the silver economy, significantly affecting organizational leadership structures, particularly in terms of succession stagnation risks and potential loss of institutional knowledge. This study aims to develop a comprehensive longevity leadership strategy to manage senior leaders and optimize leadership succession in the context of demographic transition. The research employs an integrative literature review with thematic analysis of reputable international and national journal articles published within the last five years. The findings reveal that effective longevity leadership strategies emphasize repositioning senior leaders from operational roles to strategic mentors through knowledge-sharing mechanisms and phased retirement approaches. Furthermore, successful succession in an aging workforce depends on role flexibility and the establishment of new psychological contracts that recognize and value the wisdom of senior leaders. This study contributes theoretically by proposing a dynamic succession model that bridges intergenerational gaps. Practically, it offers guidance for human resource practitioners in designing age-inclusive retention strategies and leadership transition policies.Overall, the proposed strategy supports organizational stability while fostering sustainable innovation through the optimal utilization of senior human capital.

Financial performance is an important indicator for assessing the sustainability and growth prospects of a company, where a sustained negative net profit may indicate financial and operational problems (Aminah, 2015). The purpose of this study is to analyze the financial performance of PT GoTo Gojek Tokopedia Tbk for the period 2019-2023 based on NPM, ROA, and ROE. The research method used in this study is a qualitative method with a descriptive analysis approach. The data was sourced from the official website of PT GoTo Gojek Tokopedia Tbk for the period 2019-2023.
