Project Based Learning in Science Education Research in Indonesia: A Bibliometric Analysis
No full textProject-based learning (PjBL) is increasingly recognised in science education in Indonesia as a strategy to improve students' higher order thinking skills and real-world problem solving. This article analyses the trends and patterns of PjBL research in Indonesia from 2020 to 2024 using a bibliometric approach. Research data were collected from Google Scholar, Crossref, and OpenAlex databases, then analysed descriptively qualitatively and visualised using VOSviewer. The results of the analysis showed that the majority of studies were experimental (68.36%), focusing on evaluating the effectiveness of PjBL in improving learning outcomes and critical thinking skills, particularly in the context of higher education and digital technology integration. The implementation of PjBL is considered effective in fostering students' creativity, motivation and 21st century competencies. However, there are still implementation challenges that require further study. Based on these findings, it is concluded that PjBL has great potential as a key approach in the Indonesian science curriculum. Therefore, further studies are needed to optimise its effectiveness and overcome the existing obstacles
High-Accuracy Pneumonia Classification via Ensemble Learning on Chest X-ray Imagery
No full textPneumonia continues to pose a substantial global health threat, necessitating rapid and precise diagnostic tools. The conventional manual assessment of Chest X-ray (CXR) images is time-intensive and susceptible to human error. This study introduces an automated machine learning approach that employs an ensemble learning strategy to achieve highly accurate pneumonia classification from CXR images. The comprehensive system operates through three primary phases: initial image pre-processing (involving grayscale conversion, resizing, and filtering for enhanced quality), robust feature extraction (utilizing the fusion of Histogram of Oriented Gradients (HOG) and Local Binary Pattern (LBP) descriptors), and sophisticated model training and classification. An ensemble model is trained, integrating the predictive power of Random Forest, Logistic Regression, and Extreme Gradient Boosting classifiers. Experimental validations, performed on a dedicated dataset comprising pneumonia and normal CXR images, unequivocally demonstrate that the proposed strategy achieves an impressive 97.50% overall classification accuracy, strongly supported by precision, recall, and F1-scores all at 97.50%. This superior performance, notably surpassing individual machine learning algorithms, underscores the profound efficacy of ensemble learning in delivering reliable and precise predictions for pneumonia diagnosis. Consequently, this automated methodology presents a valuable asset for medical professionals, aiding in the swift and accurate identification of pneumonia

No full textThe purpose of this study was to see the ability of Islamic Religious Education teachers at Tapaktuan Junior High School in using the Merdeka Mengajar Platform. This study uses a quantitative method. This study was located at Tapaktuan Junior High School. The sample in this study were Islamic Religious Education teachers who had a Merdeka Mengajar Platform account. There were 5 Islamic Religious Education teachers who had a Merdeka Mengajar Platform account. The data collection techniques used in this study were questionnaires and observations. The data analysis technique used a percentage formula, then analyzed using descriptive statistics. The results of this study are that most Islamic Religious Education teachers in Tapaktuan are not yet fully able to use the Merdeka Mengajar Platform. These teachers still need to improve their abilities in all the features available on the Merdeka Mengajar Platform. While a small number of Islamic Religious Education teachers are already able to use the Merdeka Mengajar Platform, they still need to improve their abilities in the Student Assessment and Work Results features.

THE ROLE OF THE QUR’AN IN THE EDUCATIONAL DEVELOPMENT OF PRIMARY SCHOOL CHILDREN
No full textPrimary school children's education is the main foundation that will shape their character, knowledge and skills throughout life. The Qur'an plays a crucial role in shaping children's education. Beyond serving as a spiritual guide for Muslims, the Qur’an is a comprehensive source of moral values, character development, ethics and knowledge. This study highlights essential teachings from the Qur’an that should instilled in children from an early age, including obedience to parents (QS. Al-Isra:23-24), monotheism (QS. Luqman:13), adherence to Allah’s commands,and noble character (akhlaqul karimah) (QS. At-Tahrim: 6).

PENGARUH PENGGUNAAN METODE PEMBELAJARAN ROLE PLAYING TERHADAP PENINGKATAN HASIL BELAJAR PAI SISWA SMP NEGERI 2 TAPAKTUAN ACEH SELATAN
No full textQuality education is highly dependent on the teaching strategies used by teachers to improve student learning outcomes. Role-playing is one approach to increase student engagement in learning. The purpose of this study was to see how the role-playing method affects student learning outcomes in Islamic religious education subjects at SMP Negeri 2 Tapaktuan, South Aceh. This study used quantitative techniques using a pre-test, post-test, control experimental design. This study involved two groups: the experimental group used the role-playing method, and the control group used the usual method. To assess student understanding, the research instrument was a written test with multiple choices and fill-in-the-blank questions. Data collection strategies included giving pre-tests and post-tests to both groups before and after the learning process. The data obtained were analyzed using a t-test for two independent samples. The results showed a significant difference between the experimental group and the control group. The average post-test score of the experimental group was 80.30, while the control group was 72.3, with a t value (2.59) greater than the t table (2.02), indicating that the role-playing approach was more effective in improving student learning outcomes compared to the lecture method. Thus, this study reveals that the use of role-playing strategies can improve students' learning outcomes, especially in terms of social skills and problem solving.Quality education is highly dependent on the teaching strategies used by teachers to improve student learning outcomes.

EXTRACTION, PHYTOCHEMICAL SCREENING, TOTAL PHENOLIC CONTENT, AND ANTIBACTERIAL ACTIVITY OF MISTLETOE ON OIL PALM (Ficus heteropleura Blume) LEAVES
No full textFicus heteropleura Blume, commonly known as mistletoe on oil palm, is a semi-parasitic plant that grows on oil palm trees. This study aimed to investigate the secondary metabolite profile, determine of total phenolic content, and evaluate antibacterial activity of ethyl acetate extract of F. heteropleura leaves. Extraction was performed using a grade maceration method. Qualitative phytochemical screening was conducted to identify major classes of secondary metabolites, and total phenolic content was quantitatively determined using the Folin–Ciocalteu method with gallic acid as the standard. Ethyl acetate extraction yielded 19.27 g of crude extract. Phytochemical analysis revealed the presence of steroids, flavonoids, saponins, and tannins. The total phenolic content was determined to be 35.730 mg GAE/g. UV-Vis spectrophotometric analysis showed characteristic absorption peaks at 475.0 nm and 432.8 nm, indicating the presence of phenolic pigments with conjugated C=O groups and a peak at 666.3 nm associated with chlorophyll, contributing to the green coloration. FTIR analysis confirmed the presence of functional groups such as O–H, C≡C, C=O, C=C, and C–O. Antibacterial activity demonstrated that the ethyl acetate extract exhibited strong inhibitory effects against Staphylococcus aureus and Escherichia coli, with average inhibition zone diameters ranging from 5 to 10 mm, indicating strong antibacterial activity.Ficus heteropleura Blume, commonly known as mistletoe on oil palm, is a semi-parasitic plant that grows on oil palm trees.
