The rapid development of technology demands solutions to optimise heat management for electronic components. Through this study, the researchers evaluated the effectiveness of various types of coolants in a liquid cooling system for electrical equipment, especially CPUs. Using design simulations conducted through SolidWorks software, this research aims to optimise the flow rate and selection of coolant type to achieve maximum thermal efficiency and reduce production and operational costs. The simulation results show that water is the most efficient coolant with significant temperature reduction compared to Ethylene Glycol (EG), Propylene Glycol (PG), and silicone oil. Water shows a temperature drop of 11.76°C, while EG and PG show a temperature drop of 8.82°C and 7.35°C respectively and silicone oil shows a temperature drop of 4.9°C. It can be seen from the simulation that water shows the most effective temperature reduction compared to EG, PG, and Silicone Oil.

Statistical analysis was used to compare the study periods, while qualitative data from in-depth interviews with 15 respondents, observations and document analysis enriched the understanding of procurement process changes through data triangulation analysis.  The results demonstrated an increased use of e-catalog, with policy changes leading to supplier diversification and price flexibility. Quantitative findings indicated a 25% increase in the volume of drug purchases through the e-catalog from 2022 to 2023, accompanied by a 15% reduction in average drug prices due to heightened competition among suppliers. Additionally, procurement efficiency improved by 30%, as reflected in the reduction of the procurement cycle time from 45 days to 31 days. These findings indicated shifting needs and procurement strategies, affecting budget efficiency and the speed of fulfilling drug requirements. In conclusion, strategic adaptations and ongoing evaluations in managing e-catalog are essential to address financial and logistical challenges, ensuring patient satisfaction and drug availability.    

Teenage non-commissioned officers face several challenges in managing their emotions, which can hinder their ability to perform their duties optimally. One of the main challenges is lack of experience. As newcomers, young non-commissioned officers may not be used to dealing with various stressful, dangerous situations or involving interactions with the public. Emotion management training is expected to provide a number of important benefits for juvenile non-commissioned officers and the police institution as a whole. One of the main benefits is increased performance. To achieve the expected goals and benefits, the implementation of emotion management training must be carried out systematically and continuously. Training can begin with an introductory session on the importance of managing emotions, followed by practical training on communication skills, problem solving, and relaxation techniques. In addition, training should include simulations of real situations that youth NCOs may encounter, so that they can apply the skills learned in relevant contexts. Training evaluations must be carried out periodically to ensure that training objectives are achieved and the expected benefits can be felt. Evaluation can be done through knowledge tests, performance observations, and participant satisfaction surveys. Overall, this emotion management training provides short-term benefits in the form of reduced stress and improved performance, while also providing youth non-commissioned officers with skills that are crucial for their long-term careers in the police force. Thus, investment in the development of these skills not only improves operational efficiency but also supports the psychological well-being and professionalism of future police officers.
