Abstract

Many teachers in kindergarten do not know how to stimulate early childhood computational thinking ability. One way to stimulate early childhood computational thinking ability is through coding games, either using digital device media or without digital device media. This article aims to analyze the types of coding games as a medium that can help stimulate early childhood computational thinking ability. The method used is a systematic literature review using descriptive qualitative data analysis to analyze relevant previous studies. This study examined 40 articles on coding games to stimulate early childhood computational thinking ability in various international journals between 2020 and 2025. The results of the analysis of theoretical studies show that coding games can stimulate early childhood computational thinking ability. This is because coding games involve children getting used to thinking logically, being structured, processing tasks systematically, and solving problems by developing the right solutions. The implications of this study can provide an overview of the types of coding games that can be implemented or practiced by teachers to stimulate early childhood computational thinking ability, by adjusting facilities in schools can use digital media or without digital media.

Abstract

The role of community participation in Islamic educational institutions, particularly Madrasah Ibtidaiyah (MI), is increasingly recognized as essential for improving institutional quality and student outcomes. This study investigates the strategies implemented by MI Takhasus Darul Ulum Ngaliyan Semarang to enhance the quality of community involvement in school management. The aim is to explore how collaborative practices between the school and its surrounding community contribute to educational development. This qualitative research employs a case study approach supported by data from observations, interviews, and document analysis. The findings reveal that the madrasah has adopted inclusive strategies such as transparent communication, involvement in decision-making, utilization of local human resources, and open participation in both managerial and instructional activities. Community participation is manifested in both physical forms (e.g., infrastructure support, event committees) and non-physical forms (e.g., teaching, training, donations). These collaborative efforts have contributed to increased public trust, a 27% rise in student enrollment over two years, improved learning environments, and a strong sense of ownership among stakeholders. The study concludes that effective community engagement, when supported by visionary leadership and contextualized strategies, serves as a foundational pillar in building a resilient and sustainable educational ecosystem in Islamic schools. The model presented by MI Takhasus Darul Ulum offers practical insights for other Islamic educational institutions seeking to strengthen community-based governance

Abstract

Peningkatan kualitas ester modifikasi gondorukem penting untuk mendukung penggunaannya pada industri perekat, cat, tinta, dan pelapis yang memerlukan bahan dengan stabilitas tinggi. Gondorukem hasil destilasi getah pinus masih memiliki keterbatasan berupa mudah teroksidasi, perubahan warna, dan bilangan asam tinggi. Namun, penggunaan gondorukem secara langsung sering kali terbatas karena sifat fisik dan kimia yang kurang sesuai untuk aplikasi industri tertentu sehingga kestabilan produk menjadi rendah. Kandungan asam resin utama dalam gondorukem yaitu asam abietat dan asam pimarat yang menyebabkan gondorukem mudah mengalami oksidasi sehingga warnanya mudah berubah dan stabilitasnya menurun jika terpapar udara terbuka karena asam-asam resin ini memiliki gugus karboksilat (-COOH) dan ikatan rangkap konjugasi (pada asam abietat) yang sangat reaktif secara kimia. Ikatan rangkap ini dapat dengan mudah berinteraksi dengan oksigen di udara. Oleh karena itu, penelitian ini bertujuan meningkatkan kualitas gondorukem melalui proses esterifikasi menggunakan gliserin dengan tingkat kemurnian berbeda, yaitu gliserin USP Grade (United States Pharmacopeia) dan gliserin Ex-Lab sebagai pembanding untuk meningkatkan sifat fisiko-kimia dan performa gondorukem. Proses esterifikasi dilakukan pada suhu 250 °C selama 90–160 menit dengan pengadukan intensif untuk memastikan reaksi berlangsung optimal. Produk ester yang dihasilkan kemudian dianalisis melalui pengujian warna, softening point, bilangan asam, dan viskositas guna mengevaluasi peningkatan mutu produk. Hasil penelitian menunjukkan bahwa proses esterifikasi mampu meningkatkan kualitas gondorukem, ditunjukkan oleh warna produk yang lebih cerah, peningkatan softening point pada kisaran 130 ± 5 °C, serta penurunan bilangan asam dibandingkan bahan awal. Nilai viskositas produk berada pada rentang Z-1 hingga Z-3 yang sesuai dengan kebutuhan aplikasi industri. Kualitas produk terbaik diperoleh pada penggunaan gliserin Ex-Lab yang menghasilkan bilangan asam lebih rendah dengan sifat fisik yang tetap memenuhi spesifikasi produk ester C-130.

Abstract

Magnetic resonance imaging (MRI) provides rich anatomical contrast for brain tumor assessment, yet routine interpretation remains time-intensive and demands high precision. This work develops a pipeline for four-class brain MRI image classification (glioma, meningioma, pituitary tumor, and no tumor) by combining automated brain-region cropping, data augmentation, and transfer learning with EfficientNetB1. Experimental results demonstrate exceptional performance, achieving an overall accuracy of 0.99 (99%) on the test set. Specifically, the model reached an F1-score of 1.00 for the no tumor class, 0.99 for pituitary, and 0.98 for both glioma and meningioma classes. Beyond reporting numerical performance, the study utilizes Grad-CAM heatmaps to verify that predictions rely on clinically plausible regions rather than spurious background cues. These results indicate that an efficiency-oriented backbone, paired with systematic preprocessing, can achieve reliable and interpretable performance for brain tumor classification tasks.

Abstract

Manual grading of English as a Foreign Language (EFL) essays often leads to inconsistent scores among educators, despite the use of rubrics. While traditional Automated Essay Scoring (AES) systems offer speed, they often fail due to high computational cost, reliance on extensive datasets, and an inability to capture holistic writing qualities such as creativity and humanistic expression. This study addresses these issues by introducing AESCORE, a novel, lightweight, and cost-effective AES framework. Our methodology centers on integrating validated rubric criteria (identified via VOSviewer analysis) with open-source Large Language Models (LLMs), specifically emphasizing a human-centered approach. We evaluated AESCORE across 100 EFL essays using several prompting techniques, including few-shot and multi-trait specialization. The system achieved its most robust performance and high scoring consistency (Quadratic Weighted Kappa QWK = 0.6660) using the DeepSeek-R1 8B LLM with few-shot prompting. AESCORE represents a significant contribution by demonstrating that sophisticated, pedagogically-aligned writing assessment and generative feedback can be achieved with accessible AI, offering a reliable alternative for improving productive writing skills in higher education.
