Abstract:This study aims to examine the application of the High-Low method, Scatterplot, and Least Squares in cost analysis, particularly in separating fixed and variable cost behavior. The research uses a library research approach…
ch by collecting and reviewing literature from textbooks, journals, and official publications related to cost estimation and cost behavior modeling. The findings indicate that the High-Low method is simple because it uses only the highest and lowest activity levels, but its accuracy is limited due to reliance on extreme data points. The Scatterplot method provides a visual representation of the relationship between cost and activity, helping identify patterns and potential outliers; however, its results may vary due to subjective judgment in determining the cost line. Meanwhile, the Least Squares method is considered the most accurate because it utilizes all available data to produce the best-fit regression line, although it requires more complex calculations and statistical understanding. Overall, the selection of the most suitable method depends on the objective of the analysis, data availability, and the level of accuracy required

donesian in everyday life functions not only as a means of communication, but also as a representation of the community's social identity. This study aims to analyze the multilingual communication practices of Central Java–West Java border communities and to explain the role of language in representing community social identity. The study uses a descriptive qualitative approach with a literature review method supported by social-contextual reflection. Data were obtained from various scientific sources discussing multilingual communication, social identity, intercultural communication, bilingualism, and multilingualism. The analysis was carried out through the stages of data reduction, theme categorization, meaning interpretation, and conclusion drawing. The findings show that border communities flexibly use Javanese, Sundanese, and Indonesian according to the context of interaction, social relations, and communication needs. The practices of code switching and code mixing are important parts of daily communication as forms of social and cultural adaptation. In addition, language use functions as a symbol of cultural identity, a means of identity negotiation, and a mechanism of social integration in a multicultural environment. The findings affirm that multilingual communication is a representation of dynamic social identity and reflects the ability of border communities to maintain social harmony amid cultural diversity.
