Abstract

This study explores the implementation of Project-Based Learning (PjBL) in the English subject as part of Kurikulum Merdeka at SMAN 9 Bandar Lampung, with a focus on both the procedure and the teachers' perceptions. Utilizing a qualitative research method, data were collected through questionnaire and interviews. The aim of the study is to investigate how PjBL is applied in the classroom setting and to gain insight into teachers' views on its PjBL application in Kurikulum Merdeka. The findings provide an in-depth understanding of the implementation process, including strategies used by teachers, and highlight the perceived benefits and obstacles encountered during the application of PjBL in Kurikulum Merdeka. These insights may contribute to enhancing the quality of PjBL practices in English language teaching, especially in Kurikulum Merdeka.

Abstract

The research aims to explore the application of historical story texts as a teaching medium in an effort to improve student literacy at SMA Negeri 2 Ciamis. The research using the Classroom Action Research method follows the Kemmis and McTaggart (1988) model which is carried out in two cycles, each consisting of planning, action, observation, and reflection. The subject of the study was 34 students in class X E 2. Data was collected through observations, interviews, and literacy tests before and after the implementation of teaching media. The results of the study show that the use of historical story texts can increase students' literacy and understanding of historical materials, as well as improve social-emotional skills, critical thinking, analytical, and empathy. This can be seen from the increase in the average student literacy score from 74% in the pre-action to 91% in the second cycle. In addition, learning activities showed a significant increase, with active participation in class discussions and group assignments. Literacy includes pre-reading, reading, and post-reading activities, which are applied through group discussions and analysis of the story texts of the novels "Laut Bercerita" and "Salt to the Sea". Through interactive discussions, they share perspectives, debate interpretations, and deepen their understanding of history. This study concludes that the application of historical story texts as a teaching medium is effective in improving students' literacy, as well as providing recommendations for the use of similar methods in their learning.

Abstract

Corn cobs (Zea mays L.) can produce charcoal as a source of carbon. Carbon is a potential candidate for reducing exhaust gas emissions containing hydrocarbons, carbon dioxide, and nitrogen dioxide. This research aims to convert corn cobs into activated carbon by adding NaCl activator in concentrations of 0%, 8%, and 16% and then compositing it with sago starch. FTIR testing occurred on the carbon from corn cobs before and after activation to analyze the functional groups in the activated carbon. The carbon was then composited with a ratio of 75:25 and subjected to SEM-EDX testing, moisture content analysis, and ash content analysis. FTIR testing revealed the carbonyl group (C-O) that could reduce emission levels. SEM-EDX testing showed that higher concentrations of NaCl activator (16%) resulted in more and smaller pores. Moisture content analysis indicated that higher concentrations of activators led to increased moisture content. Conversely, ash content analysis showed that lower concentrations of activator resulted in higher ash content. The tests concluded that the optimal composite of activated carbon from corn cobs and sago starch existed at an 8% NaCl activator concentration and a 75:25 composition, making it a promising candidate for reducing exhaust gas emissions.
