Abstract

Grade X students of SMA Negeri 2 Bontang experienced problems of low biology learning outcomes and lack of collaboration skills due to conventional teacher-centered learning. This study aimed to determine the effect of implementing the CTL (Contextual Teaching and Learning) model on students' collaboration skills and learning outcomes. The CTL model emphasizes active student involvement in the learning process, connecting material with real-life contexts, and encouraging collaboration and group discussion. This study used a quantitative approach with a quasi-experimental method and a non-equivalent control group design. Sampling was carried out by purposive sampling, with class X5 as the experimental class implementing the CTL model and class X6 as the control class using conventional methods. Data analysis was carried out using the N-Gain test and the Independent Sample t Test. The results showed that the experimental class had an N-Gain value of 0.72 (high category) while the control class had 0.59 (moderate category). The t test showed a significance value of 0.000 <0.05 for collaboration skills and learning outcomes. These results indicate a significant difference between the experimental class and the control class after the CTL model was implemented. Based on these results, it can be concluded that the application of the CTL model has a positive and significant effect on improving the collaboration skills and learning outcomes of class X students of SMA Negeri 2 Bontang in biology subjects.

Abstract

The increasingly worrying environmental damage requires us to adopt a holistic approach in education, including in Islamic Religious Education (PAI). In this case, the ecocritical paradigm provides a critical perspective on the relationship between humans and nature, which is in line with the principles of environmental theology in Islam. This study aims to explore how the ecocritical paradigm can be integrated into PAI to build ecological awareness based on Islamic values. The methods used are a qualitative approach, literature study and field research. This study reveals that Islamic teachings emphasize the concept of khilafah (human leadership over the earth), amanah (responsibility), and balance (mizan) in an effort to maintain ecosystem harmony. The integration of ecocriticism in PAI can be realized through the development of a curriculum that emphasizes environmental ethics, strengthening spiritual values ​​in preserving nature, and the application of learning methods based on experience and real action. Thus, the application of the ecocritical paradigm in PAI plays an important role in shaping the attitudes and behavior of students who are more concerned about the environment, in accordance with the principles of environmental theology in Islam.

Abstract

This study aims to analyze the level of mastery of Qur'an reading by students of the Islamic Religious Education Study Program (PAI) UIN Ar-Raniry Banda Aceh using the maqra tahsin method. The focus of the research includes three main aspects: (1) the ability to apply tajweed, (2) the understanding of tahsin reading, and (3) the influence of educational background on Qur'anic reading competence. The research uses a descriptive quantitative method with a data collection technique through direct tests using validated maqra tahsin instruments. The research sample consisted of 40 students of the class of 2021 who were selected by purposive sampling, representing four categories of educational backgrounds: tahfiz Islamic boarding schools, non-tahfiz Islamic boarding schools, aliyah madrasas, and public schools. The results of the study showed that overall, PAI UIN Ar-Raniry students had the ability to read the Qur'an with an average score of 161.25 (category B). Comparative analysis revealed significant differences based on educational background, where students graduating from tahfiz Islamic boarding schools obtained the highest scores (188.2), followed by non-tahfiz boarding schools (182.7), aliyah madrasah (171.6), and public schools (155.7). Another important finding is the weakness in mastering gharib recitation (especially imalah, saktah, and naql) and fawatihu suwar in students with public school backgrounds. Based on these findings, this study recommends several improvement strategies, including: (1) an intensive coaching program based on campus ma'had, (2) the development of structured tahsin learning modules, (3) an integrated remedial system, and (4) a more comprehensive integration of the tahsin curriculum. The implications of this research are not only important for improving the quality of learning in the PAI Study Program, but also as a basis for the development of a more inclusive Islamic education policy

Abstract

This study aims to analyze the influence of lean practices and just-in-time (JIT) practices on the competitive advantage of Indonesian manufacturing companies, with time-to-market speed as a mediating variable. A quantitative approach was employed using data from 150–200 respondents and analyzed using Structural Equation Modeling (SEM) via AMOS. The results show that lean practices significantly influence competitive advantage and accelerate time-to-market. Time-to-market speed serves as a significant mediator between lean and competitive advantage. Conversely, while JIT has a direct positive effect on competitive advantage, its impact on time-to-market is insignificant. This study is limited by its sample size and geographic focus, which may affect the generalizability of the findings to other regions or industries outside the Indonesian manufacturing sector. These findings highlight the importance of strengthening lean practices in the Indonesian manufacturing context and emphasize the need for system readiness to implement JIT effectively. This study contributes to the existing literature by examining time-to-market as a mediating variable and by providing empirical insights into how lean and JIT practices influence competitive advantage in an emerging market context.
