Abstract

Batik, an Indonesian cultural heritage recognized by UNESCO, involves a complex and time-consuming coloring process. Digitalization offers a crucial solution for the preservation and development of batik art in the modern era. This research implements a Generative Adversarial Network (GAN), specifically the Pix2Pix model, to automate the transformation of batik sketches into colored images. The primary focus is a performance comparison between the U-Net generator architecture, which excels at preserving spatial details via skip-connections, and the ResNet architecture, which is capable of learning deeper and more complex features. This study utilized 1164 paired images, divided into 931 training, 117 validation, and 116 test data points. The models were trained with consistent hyperparameters, including an Adam optimizer and a combination of L1 and binary cross-entropy loss functions, with evaluations at 50 and 100 epochs. Quantitative evaluation was performed using Peak Signal-to-Noise Ratio (PSNR), Structural Similarity Index (SSIM), and Fréchet Inception Distance (FID) metrics. The results indicate that the model with the ResNet generator trained for 100 epochs achieved the most balanced and superior performance, with a PSNR of 8.11, SSIM of 0.39, and an FID of 120.72. Overall, the ResNet generator proved more capable of producing realistic and high-quality colored batik images, offering an innovative solution to enhance the efficiency of the coloring process while supporting cultural preservation.

Abstract

This study systematically reviews the effectiveness of Project-Based Learning (PjBL) and its variants, including POPBL and PjBL-STEM, in improving problem-solving skills, higher-order thinking skills, and learning outcomes in Mathematics and Science. Drawing on ten journal articles encompassing Systematic Literature Reviews, meta-analyses, and empirical studies such as quasi-experiments and classroom action research, the findings consistently show that PjBL is more effective than conventional methods, particularly for complex subject matter. Meta-analytic evidence also indicates a large effect size in fostering scientific creativity. Beyond cognitive gains, PjBL supports the development of positive student character. However, its implementation within the Merdeka Curriculum still faces challenges, particularly teacher administrative burdens, limited time allocation, and students’ readiness for collaborative work.

Abstract

The research in this paper was conducted on Campus Teaching 5 (KM5) activities as a form of the Independent Learning–Independent Campus (Merdeka Belajar–Kampus Merdeka/MBKM) program in partner schools. It aims to provide opportunities for students to carry out activities outside the lecture classroom as a self-development experience. This research seeks to determine the effectiveness of improving literacy, numeracy, and students’ character as a result of the transformation carried out by students through campus teaching activities toward improving the quality of learning services in partner schools. The expected transformation is an increase in literacy, numeracy, and students’ character competencies through an innovative, creative, and enjoyable learning process. The research employed mixed methods, combining quantitative and qualitative descriptive approaches. Research data were obtained from weekly reports of students’ activities at the assisted partner school, namely Perti Islamic Private Elementary School in West Jakarta. The data consisted of two types: qualitative data from weekly reports and quantitative data derived from the results of the Minimum Competency Assessment (AKM) pretest and posttest. Based on the qualitative data analysis of weekly reports, the transformation process had an impact on improvements in literacy, numeracy, and students’ character competencies. This is also supported by the AKM results, which show a positive difference in the mean scores between the pretest and posttest. This indicates an improvement in literacy, numeracy, and students’ character competencies. Therefore, it can be concluded that the Campus Teaching program is effective in improving students’ literacy, numeracy, and character competencies.
