The lack of a systematic calculation approach makes it difficult for APR Nine to monitor fabric raw material inventory, resulting in raw material purchases still being based on habit and intuition. With a total inventory of 2,001 rolls and raw material usage of 1,803 rolls of fabric, there were seven times of excess stock and five times of shortage during the period of October 2024 to September 2025. The difference between the two was 198 rolls. This study uses the Economic Order Quantity (EOQ) method to analyze fabric raw material inventory control. This study uses a quantitative approach with descriptive analysis using data from the period of October 2024 to September 2025. The results of the study indicate that 1694 orders with an ordering frequency of 10 times, a safety stock of 29 rolls, and a reorder point of 35 rolls are the ideal quantities when using the Economic Order Quantity (EOQ) approach. Compared to the previous APR Nine approach, the application of the Economic Order Quantity (EOQ) method is more effective in reducing overall inventory costs from Rp. 5,011,949.35 to Rp. 4,508,824.67.

This research aims to analyze the risk factors of occupational accidents and identify effective prevention efforts within the context of Micro, Small, and Medium Enterprises (MSMEs), specifically at Inkside Sablon. This qualitative study, employing a case study approach, utilized in-depth interviews, participant observation, and documentary analysis for data collection. The findings indicate that occupational accident risk factors at Inkside Sablon are influenced by several aspects, including human factors such as lack of safety awareness and fatigue, environmental factors like inadequate ventilation and suboptimal lighting, and equipment factors such as non-ergonomic tools and insufficient maintenance. The prevention efforts implemented by Inkside Sablon are still partial and not well-structured, thus requiring the integration of more comprehensive safety programs, such as enhanced safety and health (OSH) training, provision of appropriate personal protective equipment (PPE), and improvements in management and supervision systems. It is expected that the implementation of these measures will increase worker awareness and reduce the number of occupational accidents, thereby creating a safer and more productive work environment

This research is motivated by the limited workforce at Risse Convection, where this convection has not been able to increase income significantly due to limited production capacity caused by a lack of qualified workforce. The aim of this research is to provide concrete recommendations for Risse Convection in developing an effective human resource development strategy to deal with workforce limitations and meet demand for sharia clothing products. The following is the essence of the research based on the problem formulation for copra entrepreneurs in Nagari Lansek Kadok: the majority of copra entrepreneurs in Nagari Lansek Kadok, South Rao District, Pasaman Regency, prioritize excellent service to customers and analyze the growth of their business to increase people's income. Because most of the residents of Nagari Lansek Kadok have lower middle class incomes, the community still views the purchase price given by the seller (copra entrepreneur) as reasonable. The business strategies of Nagari Lansek Kadok copra entrepreneurs, the factors that hinder these entrepreneurs, and the development strategies carried out by traders in this area are things that need to be improved if the residents of Nagari Lansek Kadok, South Rao District, Pasaman Regency can make improvements. to see an increase in their income. The reason behind this is that they continuously incorporate new ideas into the development of their company. Based on the research results, it can be concluded that the human resource development strategy to overcome the limited workforce in Risse Convection Sungai Pua, Agam Regency is: 1. Lack of workforce at Risse Konveksi resulted in reduced production of sharia clothing on the market, workforce competency occurred due to the lack of special training for employees, resulting in the work being completed more slowly or not on time. To overcome this problem, Risse Convection implements an annual reward system, and employee training is carried out personally. For new employees, Risse Convection uses its convection advantages in innovative sharia clothing designs to be able to recruit employees from the surrounding area or outside the village/nagari as well as the use of social media to promote new design innovations to reach a wider audience and increase brand visibility. 2. By using the SO (Strength-Opportunity) strategy method, namely optimizing existing strengths by taking advantage of existing opportunities. The SO (Strength-Opportunity) strategy that can be applied in increasing employment at Risse Convection is: utilizing excellence in innovative sharia clothing design to recruit employees from the surrounding area or outside the village/nagari and maintaining an annual reward system for employees who work hard to improve motivation and productivity.

This is evidenced by because the tcount for the Labor variable (3.609) is greater than the ttable (1.989) and the sig value is 0.001 <0.05. Loyalty cannot mediate the effect of working hours on wages. This is evidenced by because the tcount for the indirect effect of the Working Hours variable (0.007) is smaller than the ttable (1.989). Loyalty can mediate the effect of Labor on Wages. This is evidenced by because the tcount for the indirect effect of the Working Hours variable (2.025) is greater than the ttable (1.989). As well as Working Hours and Labor have a simultaneous and significant effect on Wages. This is evidenced by because the Fcount of (6.518) is greater than the Ftable (3.11) and the sig value of 0.002 <0.05.  

In this paper, Spline techniques have become prominent lately due to their effectiveness in addressing singular perturbation boundary value problems. These issues, defined by a boundary layer or a minor parameter associated with a derivative term, pose difficulties due to swift fluctuations in solutions adjacent to the boundary. Solutions to singularly perturbed involving both positive and negative changes in a spatial variable are shown in this review article. The methods presented here are algorithmic in nature. The singular perturbation that arises in neural activity simulation and the approaches proposed by numerous investigators between 2004 and 2024 are the only ones covered in this review. A variety of types of singularly perturbed were reviewed, including ordinary delay differential . Discovering what numerical and analytical strategies have been created in the past decade to address these types of issues is the primary objective of this review. Its secondary objective is to encourage academics to come up with novel, strong approaches to resolving related issues.

This article discusses the importance of understanding heat convection in fluids in the context of physics and engineering. Using first order Simple Differential Equations (PDS), we can analyze the temperature distribution in a fluid over time and space in high detail. PDS allows modeling heat convection by considering parameters such as temperature differences and fluid flow velocity. Numerical methods are used to complete the PDS computationally, while data collection techniques through literature studies provide an in-depth understanding of relevant theories and previous findings. With the application of PDS and numerical methods, we can better understand and predict heat transfer in fluids, which has wide applications in engineering, biology, and physics. In conclusion, this article provides a comprehensive insight into the use of PDS in the analysis of heat convection in static and dynamic fluids, with a focus on mathematical and computational approaches to better understand this phenomenon.
