Abstract

This research represents an effort in research and development with the main objectives of (i) developing a reliable and valid contextual-based learning tool, (ii) assessing the improvement of students' critical thinking skills after being taught using the developed tool, and (iii) evaluating students' responses to the learning tool. The developed learning tool includes Lesson Implementation Plans (RPP), Student Learning Materials (BAPD), and Student Activity Sheets (LKPD). The development of the learning tool follows the model formulated by Kemp, Morrison, and Ross, consisting of nine development elements, namely instructional problems, student characteristics, task analysis, instructional objectives, sequence content, instructional strategies, instructional delivery, evaluation instruments, and instructional resources. The tool was tested on students in grade XI IPA1 at SMA Negeri 6 Pinrang. The data analysis results indicate that (i) the profile of contextual-based learning tools, including Lesson Implementation Plans, Student Learning Materials, and Student Activity Sheets, is valid and reliable; (ii) there is a significant improvement in students' critical thinking skills with an increase of 0.42, categorized as a moderate improvement; (iii) students' responses to the learning tool and the implementation of learning activities

Abstract

Bedda Lotong is a traditional scrub from the Bugis tribe of South Sulawesi, Indonesia. The name ‘Bedda Lotong’ literally means ‘black powder’ in Bugis language, referring to the distinctive black colour of this scrub which comes from its main ingredient, white glutinous rice that is roasted until burnt. The purpose of this study was to determine the number of colonies of moulds (thread moulds) and yeasts (one-celled fungi) in Bedda Lotong with the addition of Eucheuma cottoni seaweed. In addition, this study also aimed to determine the level of panellists' liking through organoleptic tests. The research design used was a factorial Completely Randomised Design (CRD) with 3 levels of treatment with 3 replications. The treatment of adding Eucheuma cottoni seaweed as a microbial growth inhibitor. Data processing was done with analysis of variance (ANOVA) test and continued with Duncan test using SPSS V.23 software. Based on the results of the study, it was obtained that the effect of the addition of Eucheuma cottoni seaweed did not significantly affect the ALT/TPC test (>0.05) (0.087) and had a significant effect (<0.05) (0.003) on the Bedda Lotong pH test and in the treatment of A1 (5%) and B1 (10%) seaweed concentrations gave organoleptic test scores from panellists, namely a score of 4 (like).

Abstract

This study investigates the role of transformational leadership of school principals in enhancing the instructional quality of teachers at SMP Negeri 5 Satap Bungoro, Pangkep Regency, Indonesia. The research addresses three main problems: (1) how the principal's transformational leadership contributes to improving teacher performance in the classroom, (2) what strategies or actions the principal undertakes to elevate instructional practices, and (3) what supporting and inhibiting factors influence the process. Using a qualitative approach, data were collected through interviews, observation, and documentation involving the school principal and five teachers. The data were analyzed through data reduction, data display, conclusion drawing, and triangulation techniques. The findings reveal that the principal's transformational leadership plays a critical role in instructional improvement, marked by five key practices: presenting an inspiring leadership vision, encouraging professional growth, providing support and empowerment to teachers, fostering a collaborative and inclusive school culture, and delivering constructive feedback and evaluation. The strategies employed include the integration of the Merdeka Curriculum, mentoring and coaching of teachers, and fostering pedagogical understanding. Supporting factors include well-organized school and classroom environments and cleanliness, while the primary obstacles consist of limited funding, inadequate facilities and infrastructure, and a lack of strong teacher collaboration. In conclusion, transformational leadership contributes significantly to teacher development and improved instructional quality, especially in schools facing resource limitations. The study emphasizes the need for proactive leadership to overcome structural barriers and support effective teaching and learning.
