Abstract

In carving crafts, there are a lot of motifs or regional characteristics from which the carvings originated, making a carving work requires special skills, patience, thoroughness, and full concentration so that there are no mistakes in carving. In today's technological developments, the manufacture of wood carving crafts using a CNC (Computer Numeric Control) carving machine has begun to shift the role of traditional carving craftsmen who are currently out of business, because the results of the CNC carving machines are much better and more detailed in carving, because of that work is a machine so an operator only enters certain codes into the machine computer, in operation a CNC carving machine operator must have special skills

Abstract

This scholarly investigation delves into the strong desire for academic scholarships within the student body, especially prominent among socioeconomically disadvantaged individuals. The study aims to formulate a hybrid data mining paradigm by synergizing the K-means and C4.5 methodologies. K-means is applied for clusterization, while C4.5 facilitates prediction and decision tree instantiation. The research unfolds in sequential phases, commencing with data input and progressing through meticulous pre-processing, encompassing data selection, cleaning, and transformation. The novelty lies in successfully integrating the K-means and C4.5 methodologies, culminating in the hybrid data mining method. The dataset comprises 200 students seeking scholarships, revealing effective stratification into three clusters—cluster 0, cluster 1, and cluster 2—with 119, 48, and 33 students, respectively. The K-means method proves highly suitable, especially when combined with C4.5, for predicting scholarship recipients. A subset of 81 students from clusters 1 and 2 undergoes predictive modeling using C4.5, resulting in a commendable 85% accuracy, with 17 accurate forecasts and 3 minor inaccuracies. This research significantly enhances scholarship selection efficiency, particularly benefiting socioeconomically disadvantaged students.

Abstract

In its development, image processing is very helpful for solving problems faced by humans. Imaging processing is an image processing technique of an object to distinguish the background and the object to be analyzed. This research uses a segmentation method that can distinguish between objects and backgrounds. Analyzing objects from ultrasound images requires the expertise of an experienced doctor. In addition, there are artificial factors that make automated analysis complicated. We aim to improve natural imagery. Therefore to overcome the potential difficulties in analysis, we present four Comparison of Edge Detection, namely Gradient Image, Roberts Operator, Sobel Operator and Prewitt Operator. In image processing, data accuracy and accuracy are required as well as knowledge of statistics because image processing is related to data processing. The result of this research is to determine which edge detection is more appropriate for analyzing ultrasound images. The conclusion from this research is that from the four operators that were tried, the results of the testing process showed that the Prewit operator succeeded in detecting existing objects, even objects that function as background were successfully detected. The resulting edge detection is smoother compared to other operators.

Abstract

Human resource management (HR) training is very important in improving the performance of social organizations in society. In Koto Parak Padang Village, many social organizations focus on community empowerment, but most face obstacles in effective human resource management. Therefore, this community service aims to provide training to managers and members of social organizations in Koto Parak Padang Village about the basic principles of HR management and ways to optimize organizational performance. This training covers topics such as HR planning, recruitment, training, career development, and performance evaluation. Apart from that, participants are also trained in managing conflict and building effective communication in social organizations. The method used in this service is a participatory approach, where participants are actively involved in group discussions and share experiences. Data is collected through surveys and interviews to determine more specific training needs and to evaluate changes after training. The expected result of this activity is an increase in the capacity of managers and members of social organizations in managing human resources more professionally, which in turn can increase the effectiveness of the community empowerment programs being implemented. Thus, it is hoped that this training can make a significant contribution to social and economic development in Koto Parak Padang Village.

Abstract

The development of information and communication technology has brought significant impacts in various sectors, including education, with the implementation of a more efficient attendance system. This research aims to develop a QR Code-based attendance system integrated with Internet of Things (IoT) technology at SMK TI ZAMIGA, considering that the manual attendance process that is still used today results in recording errors of around 20%. The designed system utilizes devices such as Arduino Mega, QR Code Scanner, Ultrasonic Sensor, and NodeMCU to record student attendance automatically and in real-time. In addition, this system allows teachers to input student practicum grades, with easy data access through a website built using PHP and XAMPP technology. With the development of this attendance system, it is expected to improve efficiency, security, and student discipline in the learning process.

Abstract

Basiba is an important element in traditional Minangkabau women's clothing, possessing profound philosophical value and reflecting local cultural identity. However, amidst globalization and the dominance of popular culture, the younger generation is beginning to lose touch with traditional cultural symbols, including Basiba. This community service project aims to disseminate the visual meaning of Basiba as a Minangkabau cultural identity to the younger generation through a digital media-based visual communication design approach. This topic was chosen based on the urgency of preserving local cultural values in a format relevant to media developments and the information consumption patterns of today's young generation. Partners in this activity are student and university students in Padang City who have a Minangkabau background but have minimal knowledge about the philosophy of traditional clothing. The community service method includes observation, focus group discussions (FGDs), creation of digital visual content (such as infographics, educational videos, and social media campaigns), and evaluation through questionnaire before and after the activity. The results showed an increased understanding and appreciation of the visual meaning of Basiba, as well as an increased interest in relearning other local cultural symbols. Digital media has proven effective in bridging cross-generational communication and rebuilding a lost cultural identity. This activity underscores the importance of visual strategies and digital technology in supporting the sustainable preservation of Minangkabau culture among the younger generation.

Abstract

Kualitas air merupakan faktor utama yang memengaruhi kesehatan dan produktivitas budidaya tambak udang. Parameter seperti pH, kekeruhan, kadar garam, suhu, dan kedalaman kolam perlu dipantau secara berkala untuk menjaga kondisi optimal. Penelitian ini merancang dan membangun sistem pengukur pH dan kekeruhan air pada tambak udang berbasis Internet of Things (IoT) dengan integrasi sensor tambahan untuk mendukung monitoring kualitas air secara menyeluruh. Sistem menggunakan ESP32 sebagai penghubung ke jaringan internet sehingga data dapat dikirimkan ke aplikasi Telegram untuk pemantauan jarak jauh sekaligus pengendalian pompa air. Pengguna dapat mengakses sistem melalui RFID sebagai otorisasi awal, keypad 4x4 untuk pengoperasian manual seperti pengisian atau pengurasan air, serta LCD 20x4 sebagai penampil informasi. Sensor pH, sensor turbidity, sensor salinitas dan sensor suhu DS18B20 membaca parameter kualitas air secara realtime. Hasil pembacaan ditampilkan di LCD dan dikirim ke Telegram, yang juga dapat mengirimkan perintah untuk mengaktifkan pompa sesuai kebutuhan. Sistem dilengkapi LED dan buzzer sebagai indikator status serta relay untuk mengendalikan aliran air. Hasil pengujian menunjukkan sistem mampu memantau parameter kualitas air secara akurat dan memberikan kontrol otomatis maupun manual, sehingga dapat meningkatkan kualitas air dan mendukung keberlanjutan budidaya tambak udang.
