Abstract:Observation of Elementary School Students 14 Bone Bolango Selatan In grade 5 students using the Quiziz learning model along with the Game Based Learning method. The contextual learning model (Contextual Teaching and Learning/CTL)…
ning/CTL) is a learning approach that emphasizes the relationship between subject matter and real-life situations of students. This model aims to help students understand academic concepts by connecting the knowledge gained from school with its application in everyday life, both in personal, social, and cultural contexts. Through contextual learning, teachers act as facilitators who encourage students to actively build knowledge and skills through direct experience, problem solving, and collaboration in learning communities. Contextual learning integrates several main components, including constructivism, inquiry (discovery), asking, learning communities, modeling, reflection, and authentic assessment. This approach requires students to think critically, creatively, and innovatively, and be able to relate learning materials to real problems faced in their environment. Thus, learning outcomes are expected to be more meaningful, increase motivation, and equip students with adaptability and problem solving skills that are relevant to future life.
Abstract:Abstract: The implementation of dress code regulations in university environments is generally still carried out conventionally, requiring significant time and effort and potentially leading to subjective assessments. This…
is study develops an automatic student dress code compliance detection system using computer vision based on the YOLOv8 model. The dataset consists of 1,800 annotated images divided into eight clothing categories, split into 78% training (1,404 images), 14% validation (254 images), and 8% testing (143 images). All images underwent preprocessing and data augmentation before training the YOLOv8 model with an input size of 640×640 pixels for 50 epochs. During testing, the YOLOv8 model achieved an overall performance of Precision 0.844, Recall 0.773, F1-Score 0.802, and mAP@0.5 0.841, and was able to detect clothing objects with good accuracy and stable performance under various image conditions. The system was integrated with a Flask-based backend and a web-based frontend to enable real time detection and compliance classification, with a response time of less than 2 seconds, supporting automatic and consistent identification of student dress code compliance as “Compliant” or “Violation.”

Abstrak: Penerapan aturan berpakaian di lingkungan kampus umumnya masih dilakukan secara konvensional sehingga membutuhkan waktu dan tenaga yang relatif besar serta berpotensi menimbulkan subjektivitas penilaian. Penelitian ini bertujuan mengembangkan sistem pendeteksi kepatuhan berpakaian mahasiswa secara otomatis berbasis visi komputer menggunakan model YOLOv8. Dataset yang digunakan terdiri dari 1.800 citra beranotasi yang terbagi ke dalam 8 kategori pakaian, dengan pembagian data sebesar 78% data latih (1.404 citra), 14% data validasi (254 citra) dan 8% data uji (143 citra). Seluruh citra diproses melalui tahapan pre-processing dan data augmentation, kemudian digunakan untuk melatih model YOLOv8 dengan ukuran input 640×640 piksel selama 50 epoch. Pada tahap pengujian, model mencapai performa keseluruhan dengan Precision 0.844, Recall 0.773, F1-Score 0.802, dan mAP@0.5 0.841, serta mampu mendeteksi objek pakaian dengan akurasi baik dan performa stabil pada berbagai kondisi citra. Sistem kemudian diintegrasikan dengan backend berbasis Flask dan frontend web untuk mendukung proses deteksi waktu nyata dan klasifikasi kepatuhan, dengan waktu respons sistem kurang dari 2 detik, sehingga mampu mengidentifikasi status kepatuhan berpakaian mahasiswa ke dalam kategori “Aman” dan “Melanggar Aturan” secara otomatis dan konsisten.
Kata kunci: aturan berpakaian; deteksi waktu nyata; pendeteksi kepatuhan; visi komputer; YOLOv8.
Abstract:This study examines the role of public relations (PR) ethics in enhancing PT Kereta Api Indonesia's (PT KAI) competitive advantage in the railway industry. Ethical practices in PR are vital for fostering stakeholder trust,…
t, improving customer satisfaction, and enhancing employee engagement, all of which contribute to sustainable growth and market leadership. Adopting a qualitative research design and a case study approach, the research investigates how ethical principles such as transparency, integrity, equity, respect, and responsiveness are applied within PT KAI’s operational and strategic frameworks. Data collection involved document and thematic analyses, emphasizing ethical practices’ impact on stakeholder relationships and competitive outcomes. The findings highlight that PT KAI’s ethical initiatives strengthen its reputation, promote customer loyalty, and support a positive workplace environment. Despite these successes, challenges remain, including the absence of formalized ethical guidelines and the need for ethical leadership. The study concludes that integrating PR ethics into organizational culture enhances competitive advantage and ensures long-term sustainability in a dynamic market.
Abstract:The research was carried out at Koffee Talk, which is located inside the Radja Hotel Semarang. The purpose of the study was to evaluate and explain the influence that the quality of service and marketing mix had on the level…
evel of satisfaction experienced by customers. Questions and answers are gathered via the use of questionnaires. Participants in the research totaled 96 individuals. It is anticipated that the findings of the study would be beneficial to both management and customers. Customer happiness is impacted by both the quality of the service and the marketing mix. The findings of the double regression analysis demonstrate the impact of independent factors on dependent variables, as well as the validity and rehabilitation tests, as well as the testing of hypotheses. It is clear that in order to achieve higher levels of customer satisfaction, a combination of marketing and service is required.
