Abstract

This research focuses on modeling and simulating temperature and pressure parameter settings in geothermal power plants using MATLAB software. Geothermal power plants utilize geothermal heat as an energy source to produce electricity, so controlling temperature and pressure parameters is a key factor in optimizing system performance. The method used in this research includes developing a mathematical model of a geothermal power generation system, followed by numerical simulations to evaluate the dynamic response to variations in operational parameters. Simulation results show that proper regulation of temperature and pressure can increase plant efficiency and operational stability. In addition, this study also explores the influence of various parameter setting scenarios on the power output and energy consumption of the system. Implementation of the model in MATLAB makes it easy to visualize and analyze data, and allows real-time simulations needed for fast and accurate decision making. In conclusion, this research succeeded in showing that modeling and simulation using MATLAB is an effective tool for optimizing temperature and pressure parameter settings in geothermal power plants, which in turn can increase overall system efficiency and reliability.

Abstract

The development of digital technology has driven the growth of e-commerce as one of the main solutions in meeting consumer needs, including in the coffee sector. This study aims to design a user interface (UI) and user experience (UX) for an Android-based coffee e-commerce application with a Design Thinking approach. The Design Thinking method is applied in five stages: empathize, define, ideate, prototype, and test. These stages allow for an in-depth understanding of user needs, identification of key problems, development of creative ideas, prototyping, and iterative evaluation based on user feedback. The results of the study indicate that the resulting design is able to increase user convenience, efficiency, and satisfaction in shopping for coffee online. The application design displays intuitive navigation, attractive visuals, and functional features such as product search, user reviews, and secure payment methods. Prototype trials showed a high level of success in meeting user needs, with an increase in user satisfaction of up to 85%. This study makes a significant contribution to the development of Android-based e-commerce applications, especially in the coffee sector, and shows the great potential of implementing Design Thinking in creating user-centered digital solutions.
