Management of household waste in Final Disposal Sites (TPA) faces a serious problem, where most of the waste accumulates and is difficult to decompose due to its complex nature. This condition substantially inhibits natural decomposition processes and limits the effectiveness of recycling efforts. Pre-processing operations, such as sorting and crushing, which are still dominated by manual methods, are proven to be inefficient, high-risk, and require large allocations of land resources and manpower. Therefore, automated technological innovation is needed to facilitate the efficient separation of organic components from inorganic materials (packaging). This research was conducted to determine the design and structural strength analysis of a hammer mill type depackaging machine, carried out using Solidworks software. Structural analysis simulation utilizes Finite Element Analysis (FEA) to determine the structural strength of the machine. The specifications of the hammer mill type depackaging machine include a capacity of 3000 kg/hour, a hammer mill input power of 12 KW, and a rotational speed of 2500 rpm with a torque of 34.54 Nm. Meanwhile, the screw conveyor input power is 0.75 KW and the rotational speed is 20 rpm. The FEA simulation analysis results for the hammer mill type depackaging machine showed that the maximum Von Mises stress value recorded is 3,022×10^7   N⁄m^2 , the maximum displacement value measured is very minimal, namely 2,793×10^(-1)  mm, and the Factor of Safety (FOS) obtained is 8.3. This FOS value significantly exceeds the required minimum safety limit (>3), confirming that the machine design has optimal reliability, fatigue resistance, and structural integrity for operation under intensive working conditions at the TPA. The conclusion of this study indicates that the engineering design of this hammer mill type depackaging machine is safe and meets structural technical requirements to proceed to the implementation phase, potentially becoming a sustainable technological solution in improving the efficiency of waste pre-processing.

This study examines the influence of firm size, profitability, solvency, and public accounting firm (KAP) size on audit report lag among food and beverage companies listed on the Indonesia Stock Exchange (IDX) during the 2021–2024 period. The research employs purposive sampling, involving 68 companies with a total of 272 observations, and uses multiple linear regression analysis after passing all classical assumption tests. The findings reveal that profitability measured by Return on Equity (ROE), solvency measured by Debt to Assets Ratio (DAR), and KAP size have a significant effect on audit report lag. Meanwhile, firm size (measured by total assets and total sales), profitability measured by Return on Assets (ROA), and solvency measured by Debt to Equity Ratio (DER) show no significant effect. These results indicate that companies with higher ROE, greater DAR, and those audited by Big Four accounting firms tend to complete their audit process more promptly. The study highlights that both financial performance and auditor characteristics play essential roles in determining audit timeliness. Overall, this research provides valuable insights for management, auditors, investors, and regulators to enhance the efficiency and reliability of financial reporting.  

This research explores how transformational leadership, work environment, and workload affect the organizational commitment of the Kebumen Regency Education, Youth, and Sports Office.

The findings reveal that transformational leadership does not have a significant effect on organizational commitment. On the other hand, an excellent work environment greatly enhances employee welfare and has a substantial positive impact on organizational commitment. Workload is also found to positively affect organizational commitment, as a proportional workload encourages higher levels of employee accountability. Together, these three independent variables explain 55.4% of the variance in organizational commitment, with other factors accounting for the remaining portion. The study concludes that improving the work environment and managing workload effectively are key factors in increasing organizational commitment.

APIs (Application Programming Interfaces) have become a key component in the development of modern digital products and the transformation of cloud-based services. Its ability to provide structured access to data and enable cross-platform integration makes APIs at the core of the enterprise's digital architecture. However, the high level of API openness poses increasingly complex security challenges, including potential data exploitation, injection attacks, credential misuse, and exploitation of business logic loopholes. This article examines the strategic role of APIs in the digital ecosystem, analyzes the operational risks that arise from API exposure, and evaluates the effectiveness of basic defense mechanisms such as API Gateways and Web Application Firewalls (WAFs). The findings of the study show that while both solutions play an important role in controlling access, filtering, and mitigating attacks at the surface layer, they have not been able to provide comprehensive protection against modern API threats that are dynamic, distributed, and often exploit weaknesses at the application and business logic levels. Therefore, a more holistic, layered, and sustainable API security approach is needed, including anomalous behavior detection, API abuse protection, and real-time monitoring to maintain the integrity and reliability of digital services.

The blue economy is widely promoted as a pathway to sustainable development, yet women’s enterprises remain marginalized by structural barriers. This study investigates whether support systems directly influence the sustainability of coastal women’s businesses in Bulukumba South Sulawesi, Indonesia, while applying the Quintuple Bottom Line (QBL) and Theory of Change (Toc) frameworks. A quantitative design using survey data from women-led micro, small, and medium enterprises (MSMEs) was analyzed through structural equation modeling (SEM). The model assessed the reliability of constructs and tested the hypothesized effect of support systems including access to finance, social support, and public policy on sustainability outcomes. Findings reveal that although the measurement model demonstrated reliability and validity, support systems showed no significant direct effect on sustainability. This result contrasts with much of the existing literature but aligns with recent studies emphasizing mediation through financial literacy, managerial capacity, and institutional scaffolding. The study thus adds nuance by demonstrating that external interventions, in isolation, are insufficient for sustaining women’s enterprises in coastal contexts. The research contributes theoretically by extending QBL and Toc to gendered coastal entrepreneurship and practically by highlighting the need for integrated, gender-sensitive policies. Future research should examine mediating and moderating mechanisms that translate support into long term sustainability.
