Abstract

The heat transfer process in the industrial world is the most important thing to pay attention to, especially in industrial equipment that works at high temperatures, one of the heat exchangers commonly used in the industrial world is a heat exchanger which is used to exchange heat between fluids of different temperatures. Therefore, it is necessary to pay attention to the performance of the heat exchanger. In the shell and tube type heat exchanger, apart from using baffles which aim to direct the flow on the shell side, it also aims to increase the rate of heat transfer that occurs between the working fluids by causing flow turbulence on the shell side. The results of this study are to obtain the heat transfer that occurs in the shell and tube in the heat exchanger, and to obtain the total heat transfer coefficient

Abstract

This study focuses on the impact of Betawi Language elements on the morphological characteristics of teenagers in Jakarta. Previous research has highlighted that Morphological Interference is the most common form of interference. Similarly, the investigation within Jakarta's coverage area yielded similar results. The study employs a qualitative methodology, utilizing descriptive analysis techniques while incorporating statistical data for reference purposes. The data analyzed in this research consists of sentences in which the Betawi language interferes, specifically regarding affixation, reduplication, composition, and micronization. The findings reveal the presence of morphological interference in the Betawi language concerning morphological variables related to affixation and reduplication. Specifically, the Betawi language demonstrates interference in morphological variables by attaching prefixes, suffixes, and confixes. Additionally, the study indicates the presence of Betawi language interference in speech morphology through reduplication, particularly dwilingga. However, no instances of Betawi language morphological interference were identified concerning composition and micronization in the speech of teenagers in Jakarta

Abstract

Research plays a crucial role in preserving languages by enhancing their use as a means of knowledge. Language serves various functions, including cognitive, enabling users to express thoughts. This research employs a combination of analysis methods, incorporating field data collection, classification, analysis, and concluding. It is important to integrate this data with information obtained from reference literature. Both qualitative and quantitative methods are utilized to achieve optimal outcomes at each stage of the research process. Preserving a language's distinct characteristics is essential for it to continue serving as a medium of knowledge. One effective approach for researching endangered languages is Sociosemiotic or Social Semiotic analysis. Sociosemiotics provides a valuable framework for understanding the dynamic signs and symbols present within a society. These variables of signs and symbols are crucial for effectively analyzing problems and developing solutions. The most important thing is to find the authenticity of the original form of the endangered language, see the actual conditions of the endangered language, investigate the impact of the endangered language as seen from the decrease in a variable in the communication habitat of its users, and formulate a preservation/preservation model for the endangered language
