ABSTRACT
This study aims to analyze the increase in student activity and learning outcomes in water chemistry materials through the application of the Two Stay Two Stray (TSTS) cooperative learning model. The background of this research is the low level of student activity and learning outcomes in water chemistry courses which are often taught conventionally, so that they do not encourage interaction and deep understanding. This study uses a quantitative approach with a Quasi-Experimental design of the Nonequivalent Control Group Design. The research population is students of the Sains study program who take the Environment Chemistry course. The sample was selected by purposive sampling, consisting of two classes: one experimental class applying the TSTS model, and one control class using conventional learning methods. Activity data was collected through observation sheets, while learning outcome data was obtained from pretest and posttest given to both groups. Data analysis was carried out descriptively and inferentially. The learning outcome data was analyzed using the Independent Sample T-Test or Man-Whitney U Test after the normality and homogeneity test, as well as the calculation of N-Gain to see improvement. Activeness data was analyzed descriptively as a percentage. The results of the study show that the Two Stay Two Stray learning model is significantly able to increase student activity and learning outcomes in Water Chemistry materials compared to conventional learning methods. The N-gain Score value in the table in the experimental class was in the high category, which was 0.74, was in the high category, which was 0.30 > N-gain > 0.70, while in the control class, the value of 0.68 was in the 0.30 ≤ N-gain ≤ 0.70 was in the medium category. The increase in activeness can be seen from the active participation of students in group discussions and information sharing, which is positively correlated with increased understanding of concepts.

An Analysis of Compound Words Usage on the @PopBase's X Account in 2024
Get PDFThis study aims to analyze the use of compound words on the @PopBase X account in 2024. Using a qualitative approach and the theory of Delahunty and Garvey (2010), this study focuses on identifying three types of compound words: endocentric, exocentric, and copulative. Data were collected from @PopBase tweets throughout 2024, specifically those related to entertainment news and pop culture. The findings of the study revealed that endocentric compounds dominated the data, with terms such as soundtrack and fanbase being the most frequently used. Exocentric compounds, such as box office and blockbuster, and copulative compounds, such as singer-songwriter and action comedy, also appeared but were less frequent. The study also found that most of the compounds had transparent meanings and the compounds in the posts functioned as nouns. These findings suggest that the use of compound words on @PopBase helps facilitate concise and engaging communication, especially in the fast-paced digital environment of platform X. This study contributes to the understanding of word formation in X application and highlights the evolving role of morphology in online entertainment communication
