Fenomena arus inrush merupakan kondisi transformator pada saat pertama kali dihubungkan dengan sumber tegangan dan menghasilkan lonjakan arus yang tinggi. Arus inrush dapat menyebabkan gangguan dan akan mempengaruhi kinerja dan sistem proteksi pada transformator. Tujuan dari studi ini adalah untuk mengetahui karakteristik arus inrush pada transformator tiga fasa dengan besar leg yang berbeda sehingga dapat diketahui pula pengaruh perbedaan besar leg dengan arus inrush yang dihasilkan. Pada studi ini dilakukan pengujian dengan mengambil data arus inrush pada transformator uji 3 fasa 5 kVA tipe inti core konvensional, dengan metode pengukuran berbasis eksperimen. Pengujian pada transformator dilakukan pada saat kondisi transien, yaitu saat transformator melakukan energizing. Pengujian ini dilakukan dengan cara menguji setiap fasa secara bergantian dan menguji ketiga fasa secara bersamaan. Hasil pengujian menunjukkan bahwa fasa S yang memiliki leg paling besar diantara kedua fasa lainnya, menghasilkan arus inrush dan arus no load yang paling tinggi dibandingkan kedua fasa lainnya. Selain itu, pada fasa S menunjukkan kurva magnetisasi inti transformator pada area non-saturasi. Hal ini mempengaruhi karakteristik arus yang dihasilkan transformator Kata Kunci: Arus Inrush, Eksperimen, Transformator 3-Fasa, Leg Berbeda.

The agribusiness system in Pagergunung Village has not been fully functioning properly. Based on the results of the survey that the author conducted, production was not optimal due to several factors including extreme weather changes, pest and disease attacks and low knowledge of the technology used and declining sales prices at harvest. In this era of the industrial revolution 4.0, all areas of life will involve the role of information and communication technology, one of which is in the field of agriculture. The application of technology in agriculture can be realized in the form of making a website for selling agricultural products so as to increase people's income through the creation of an agribusiness system, especially a marketing system through an e-marketplace that is connected to a paymet gateway. From the results of the blackbox test with a total of 25 respondents stated that online marketing media through the SIADIT e-marketplace application facilitates product promotion so as to increase farmers' income.

This research explores imagination therapy as a creative method aimed at providing visual therapy for ten schizophrenic clients, referred to as "chosen people." Utilizing the concept of hyperreality, the therapy seeks to reactivate cognitive abilities and minimize delusions and hallucinations. Hyperreality is constructed from imagined data, drawing from clients' personal documents, archives, and daily life elements, such as songs, objects, and routines. Imagination therapy integrates clients' unrealized stories, desires, and imaginations with hyperrealistic visuals through collaborative sessions. The process involves repeated evaluations to refine visuals based on client preferences and feedback, ultimately culminating in the creation of a visual lab. The therapy’s effectiveness is assessed using the PANSS (Positive and Negative Syndrome Scale), measuring symptom changes over time. The findings indicate that imagination therapy not only fosters confidence in clients’ ability to process their expectations but also helps reactivate cognitive functions and empower desires. The concept of hyperreality proves essential in enhancing self-confidence and enabling clients to realize their deepest desires, contributing to their overall mental health recovery. This study highlights the potential of using artistic and technological methods in schizophrenia treatment.

Agriculture is a vital sector that plays a role in fulfilling food needs, economic development, and community welfare, particularly in rural areas. However, most farmers in Lebak Village, Grabag District, Magelang Regency, still rely on conventional methods that are inefficient and do not yet utilize modern agricultural technology. This community service activity aims to enhance farmers' understanding and skills related to appropriate technology, specifically a sensor-based automatic soil moisture irrigation system, a portable soil pH meter, and a circle model seed planting pattern. The method employed in this activity was the socialization of appropriate technology. The results show a significant improvement, with the average understanding score increasing by 91%, 85% of farmers being able to operate the pH meter, water use efficiency rising by 28%, and corn planting time becoming 44% faster. These outcomes prove that participatory socialization based on direct practice is effective in boosting farmers' capacity, both cognitively and technically. This activity is expected to serve as a model for strengthening the adoption of modern agriculture based on adaptive, productive, and sustainable precision technology at the village level.

Although previous studies have examined the use of video-based project learning, research that specifically investigates its impact on the development of creative thinking skills in Information Technology education remains limited. This study aims to analyze the influence of integrating Video Project-Based Learning (VPBL) on the creative thinking abilities of students in a Diploma Program in Information Technology. Employing a mixed-methods design with a quasi-experimental approach, the study involved 20 students and collected data through the Torrance’s Test of Creative Thinking, classroom observations, and reflective journals. The data were analyzed using thematic analysis and descriptive statistics to map changes in students’ creative thinking skills. The findings indicate a significant increase in creative thinking abilities, with an average score rise of 0.79 points across the four measured dimensions of creativity. These results enrich theories of project-based learning and creativity, while providing deeper insights into the application of multimedia in vocational education. The study concludes that the use of video in learning can enhance students’ creative abilities and recommends that educational institutions integrate this model into their curricula. The implications include theoretical contributions to the development of the project-based learning literature and practical recommendations for designing more innovative curricula that are relevant to the needs of the digital industry, as well as opening opportunities for further research on the integration of multimedia technology in various fields of learning.

Diabetic Foot Ulcers (DFU) are a serious complication of diabetes mellitus and carry a high risk of lower extremity amputation if not treated in a timely manner. The conventional classification process, which relies on visual inspection by clinicians, tends to be subjective and inconsistent. Therefore, this study proposes a multiclass classification model for DFU based on the Wagner Scale (Grades 0–5) using the ResNet-50 architecture with a transfer learning approach as the core machine learning method. The dataset used in this study consists of 1,415 clinical wound images that were annotated and verified by medical professionals. The dataset is highly imbalanced, with 543 images in Grade 0, 110 in Grade 1, 252 in Grade 2, 145 in Grade 3, 293 in Grade 4, and only 72 images in Grade 5. To address this imbalance, random oversampling (ROS) was applied, in addition to standard preprocessing techniques such as normalization and data augmentation to increase training data diversity.Experimental results demonstrate that the proposed model achieves high classification performance based on accuracy, precision, recall, and F1-score. Specifically, the model obtained a precision of 0.96, recall of 0.95, and F1-score of 0.95, indicating consistent and robust classification performance across all Wagner grades. The best configuration (ResNet-50 + ROS) successfully improved the classification performance across minority grades (e.g., Grade 1 and Grade 5). Moreover, the model consistently identifies minority classes and does not exhibit signs of overfitting. Model optimization using the Adam optimizer and data balancing strategies significantly improves the generalization capability of the classifier. These findings indicate that the proposed model is not only effective for automatic DFU classification, but also has great potential to support objective clinical decision making and accelerate diagnosis, particularly in healthcare facilities with limited resources.
