Abstract

The objective of this research was to find out students’ positive perceptions on the use of project-based learning in writing class. The project-based learning focused on the students’ perceptions and the benefits of their writing project. The data were collected through a questionnaire adapted from Unumeri, G.O (2009) and also interviews. The research method used a quantitative approach with descriptive statistic data analysis techniques. The subjects of this research were 60 senior high school students in SMA Qur’an Darul Fattah. The questionnaire results showed that most of the students had positive perceptions on the use of project-based learning. They agree that the material used in project-based learning is clear, interesting, and easy to understand. In addition, the use of project-based learning in learning activities can enhance their motivation and improve their writing skill. Furthermore, students have positive perceptions toward the teacher’s ability in guiding and facilitating them in project-based learning in writing class.

Abstract

Indonesian health data for 2024 has multidimensional characteristics with a large number of interconnected variables, leading to high complexity in the analysis and visualization process. This complexity poses a challenge in generating information that is easy to understand and can support data-driven decision-making. This research aims to implement the Principal Component Analysis (PCA) method as a technique for dimension reduction and visualization of Indonesian health data. The research method used is a quantitative approach with descriptive-exploratory secondary data analysis. The research stages include data pre-processing, PCA implementation, principal component determination, variable contribution analysis, and data visualization using scatter plots and biplots. The research results show that PCA is able to significantly reduce the number of variables while still retaining most of the main information contained in the data. Principal component analysis-based visualization produces clearer and more easily interpretable patterns and structures in health data. Thus, PCA has proven effective in simplifying the complexity of national health data and supporting the presentation of more informative and actionable information for decision-making in the health sector.
