Abstract

Computational fluid dynamics (KDF) is a commonly used method to solve physics cases that have the advantage of reducing operating costs, especially in the study of cooling systems in engines. In this study, the engine cooling system observed was located at the Diesel Power Plant (PLTD), Batakan. The cooling system on the engine has several important components that affect performance, one of which is the radiator. The condition of the radiator is observed with different fin designs, namely ideal conditions with fins (100%), 75%, and 50%. KDF helps to provide a detailed analysis of the performance of the engine cooling system. Under ideal conditions, the value of the temperature difference between the inlet and outlet in high temperature (HT) and low temperature (LT) pipes is 220C. From this study gave results, the condition of the radiator fins that were not ideal resulted in a decrease in temperature difference between the inlet and outlet in the HT and LT pipes.

Abstract

This research was conducted to design a modeling that is used to build an Android-based Tajweed science learning system. The method used in the development of the Android-based Tajweed science learning system is the waterfall method. The learning system that was built adopted several components of LTSA. The system that was built focuses on the achievement of learning materials Tajweed science as part of the overall learning process. To design the system modeling in this study, UML was used. After the system design is complete, the design is implemented into Java coding which will later be exported into an apk that can be installed on an Android device. the results show that the system can run well on Android version 5.0, all features in the system can run well and in accordance with the design of the system designed with UML. Learning of Tajweed knowledge based on Android makes it easier to learn because it can overcome the learning of Tajweed science which is physically not possible and overcome the limitations of time, place and access. UML modeling is very suitable to be used in design to design a system model used in the application of the study of recitation.
