This research is motivated by the lack of availability of learning media usage and conventional learning. Therefore, an effectiveness test of the periodic table of the ladder media was conducted to improve the learning outcomes of students at SMKN 1 BP BR on the topic of periodic table of elements. This research is a pre-experimental study aimed at assessing the effectiveness of media usage using data analysis techniques through pretest-posttest assessments. The population in this study is the students of class X TBSM SMKN 1 BP BR. The research instrument is a learning outcomes test consisting of 25 multiple-choice questions that have been pilot tested. The data analysis techniques used are the t-test to determine differences in learning outcomes and the N-Gain test to determine the improvement in students' understanding. The results of the study show that there are differences and improvements in students' learning outcomes. This is evidenced by the average posttest score of 86.67. The improvement in learning outcomes is also supported by hypothesis testing conducted with the t-test, obtaining a t-value (3.45) > t-table (1.21). Another supporting evidence is the average N-Gain test score of 0.75 with a high category. Thus, it can be concluded that the use of the periodic table of the ladder media is effective in improving students' learning outcomes with a high category. This media is suitable for chemistry learning that is symbolic, as it will be more engaging and challenging through direct student involvement in the learning process.

Education plays a very important role in developing the human resource potential of a country. This research examines how Indonesian language teachers at SMP Negeri 2 Padamara reflect on their experiences in facing the newly implemented Merdeka Curriculum. The Independent Curriculum is an educational approach that focuses on student needs, so teachers face additional challenges and responsibilities in implementing it. This research aims to explore the perspectives and experiences of Indonesian language teachers at SMP Negeri 2 Padamara in facing the Independent Curriculum. The research method used was descriptive qualitative with interview techniques with Indonesian language teachers at SMP Negeri 2 Padamara. Data validity testing was carried out using data source triangulation techniques. The research results show that the Merdeka Curriculum is considered relevant and oriented towards meeting student needs. Teachers have tried a variety of tailored learning strategies, including content, process, and product differentiation. Apart from that, this research also highlights the important role of learning modules and media in the Independent Curriculum, as well as the importance of In House Training (IHT) as an effort to increase teachers' understanding of the newly implemented curriculum. It is hoped that these findings can provide a valuable contribution in the development of educational strategies and provide the necessary support to teachers and other educational institutions that are implementing the Merdeka Curriculum.
