Abstract

Kabupaten Aceh Timur memiliki sebuah desa yang berpotensi besar memiliki buah-buahan hutan yang belum tereksplorasi. Potensi sumber daya genetik tumbuhan buah-buahan di lokop terutama yang masih hidup liar di hutan belum dimanfaatkan secara optimal. Jenis tumbuhan buah-buahan hutan belum banyak di kenal dan belum terdokumentasi dengan baik. Hal ini karena secara ekonomis buah-buhan lokal masih dianggap kurang penting. Dengan Terbatasnya informasi terkait buah-buahan asli lokop khususnya yang masih tumbuh liar menyebabkan keberadaan sumber daya genetik buah-buahan tersebut menjadi terancam. Padahal buah-buhan hutan masih memiliki bentuk dan cita rasa yang sangat khas dan umumnya memiliki kandungan gizi yang baik. Eksplorasi dan konservasi sumber daya genetik merupakan salah satu pilihan yang dapat di lakukan untuk menyelamatkan keragaman jenis tumbuhan buah-buahan asli lokop. Penelitian ini bertujuan untuk mengetahui jenis buah-buaha lokal di daerah lokop kecamatan Aceh timur. Berdasarkan hasil observasi bahwa telah di temukan 52 spesies buah yang terdapat di kawasan hutan lokop. Diantaranya berhabitat liar sebanyak 27 spesies, dan yang berhabitat budidaya sebanyak 25 spesies. Banyaknya spesies yang ditemukan di hutan liar karena hutan di daerah lokop masih terjaga, tumbuhan yang dibudidaya merupakan tumbuhan yang di ambil dari hutan dan di tanam di perkebunan warga karena tumbuhan tersebut dapat menghasilkan buah dan dapat di makan oleh masyarakat sekitar.

Abstract

One of the obstacles in the learning process at SMAN 1 Sultan Daulat is that some students have low interest in learning. This is thought to be due to the lack of variations in learning models, so that the percentage of students who achieve the KKM score is only 65%. This research aims to determine the improvement in student learning outcomes by implementing the Team Games Tournament model. This research is quantitative research. The population in this study were all class XI students of SMAN 1 Sultan Daulat, totaling 46 students. The sample used was class XI Science 1. The data collection technique for the learning outcomes test was in the form of multiple choice. The data analysis technique was carried out quantitatively, namely by hypothesis testing and N-gain testing. The results of the research show that there is an increase in student learning outcomes based on the results of hypothesis testing with tcount > ttable, namely 18.25 > 2.074 at a significance level of 5%. The increase in student learning outcomes can be seen from the average normalized N-gain result of 0.67 with the criteria for increasing learning outcomes being 67% in the medium category. Thus, the hypothesis in the research was accepted and it was concluded that there was a significant increase in student learning outcomes from implementing the Team Games Tournament model.

Abstract

This 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.
