Abstract

Guidance and Counseling is a service provided to students to help them develop their potential optimally. Detecting students' facial expressions in the counseling room plays a crucial role in assisting counselors in understanding the emotional state of students who may need help, such as depression, anxiety, or stress, as they often find it difficult to express their feelings verbally. Therefore, this research will focus on 7 types of facial expressions: Anger, Disgust, Fear, Happiness, Neutral, Sadness, and Surprise. To classify these facial expressions, a Convolutional Neural Network (CNN) technique will be used, which identifies objects based on color and contours in an image. The aim of this research is to create a CNN model that can detect students' facial expressions during counseling sessions. In this study, the machine learning life cycle method is also employed as a stage in building the CNN model, starting with data collection with a total of 618 images, data cleaning, labeling the data, splitting the data into training and testing data with an 80% training data and 20% testing data ratio, creating the CNN architecture, training and evaluating the created model, and finally implementing it using a webcam. The results of this research show that the model achieved an accuracy of 33%. However, the facial expression detection features using the CNN model successfully detected students' facial expressions despite having a low prediction accuracy rate. Keywords— Convolutional Neural Network, Facial Expression Detection, Guidance Counseling, Machine Learning, Webcam

Abstract

Abstract — Service quality and organizational effectiveness are highly influenced by employee performance. At Wahaha Seafood Lampung, the process of delivering information such as memos, work reminders, and performance evaluations is still conducted manually, resulting in delays in information dissemination, suboptimal employee coordination, and difficulties in monitoring employee performance in an integrated manner. These issues highlight the need for an information system capable of supporting internal communication and real-time employee performance evaluation. This study aims to design and develop a web-based and Android-based application for information dissemination, notification delivery, and employee performance evaluation using Firebase Cloud Messaging (FCM). The research employed an applied research approach with a system development methodology using the Waterfall model, which consists of requirements analysis, system design, implementation, testing, deployment, and maintenance stages. The system was developed using the Laravel framework for the web application, Flutter for the Android application, MySQL as the database management system, and Firebase Cloud Messaging (FCM) as the real-time notification service. The system provides features for memo distribution, work reminders, automated notifications, and weekly performance evaluations for Persons in Charge (PICs) and staff based on indicators including attitude, discipline, creativity, and communication. The testing results indicate that all system features functioned according to the specified requirements, including both manual and automated real-time notification delivery as well as proper management of performance evaluation data. Therefore, the developed system is capable of improving internal communication effectiveness, facilitating employee performance monitoring, and supporting increased organizational productivity in a more structured and integrated manner.   Key word — Performance, Android, Webservice, Firebase Cloud Messaging (FCM), Company, Evaluation System

Abstract

The increasing use of digital documents in export-import activities, especially in government agencies such as the Directorate General of Customs and Excise, has the potential to pose a threat of leaks if not supported by an adequate security system. The design of this security system aims to design and develop a web-based digital export-import document security system by implementing the Advanced Encryption Standard (AES) 256-bit encryption algorithm. The system development was carried out using the Waterfall method by utilizing PHP, HTML, CSS, JavaScript, and MySQL database technology. This system implements encryption and decryption mechanisms on export-import documents in PDF and DOCX formats. Test results indicate that encrypted documents cannot be accessed without a valid decryption process, and data integrity is maintained referring to the AES-256 validation results. This system is able to increase the level of digital document security and minimize the risk of data leaks in a web-based system environment. This research requires the addition of a multi-layer authentication mechanism, the implementation of a more comprehensive encryption key management system, and the development of applications for mobile platforms. The rapid development of information technology has changed the way individuals, organizations, and government institutions manage and distribute information. One of the main impacts is the increasing use of digital import-export documents as the primary medium for storing and exchanging critical data. These documents generally contain sensitive information, requiring security mechanisms capable of ensuring data confidentiality, integrity, and authenticity during storage and distribution.

Abstract

This article departs from the view that methods play an important role in the process of learning Arabic, especially in Islamic educational institutions. With the development of technology and the rapid digitization in the world of education, modern technology-based learning methods are beginning to dominate. Nevertheless, there is a gap between traditional and modern approaches. Traditional methods are considered less responsive to technological advancements, while modern approaches sometimes overlook the values of depth, perseverance, and meaningful learning that have long been upheld in traditional methods. This poses a challenge in creating an effective, relevant, and balanced Arabic language learning system. This research takes a case study at SDIT Al Anis Kartasura Sukoharjo, which has a system that adopts a Pesantren (Islamic boarding school) and is combined with the government curriculum, promoting and developing an integration of the National Curriculum from the Ministry of Education, Ministry of Religious Affairs, and the distinctive Integrated Islamic Schools, namely the system oriented towards Pesantren developed by the Al-Anis Kartasura foundation. This study is descriptive qualitative, with an analysis using an interactive model, namely data reduction, data presentation, and conclusion drawing. The results are as follows: First, the integration of traditional and modern methods in Arabic language learning in the digital era has a positive impact on the effectiveness and quality of the teaching and learning process. Second, learning at SDIT Al-Anis is like at a Pesantren, collaborated with the current government curriculum. The integration of traditional and modern methods not only enables transformation in Arabic language learning but also opens opportunities to enhance the quality of education that is contextual, adaptive, and competitive in the digital era.

Abstract

The internal communication network of student organizations plays a strategic role in supporting the success of programs while strengthening solidarity among members. This study examines the communication network patterns within the Gelora Ramadhan program committee of the Campus Ambassador of Universitas Trunojoyo Madura (UTM) and their contribution to organizational internal solidarity. A quantitative descriptive method with a Social Network Analysis (SNA) approach was employed, involving 24 committee members as the unit of analysis. Data were collected through interviews and dichotomous-scale sociometric questionnaires, subsequently processed using UCINET VI software and visualized through NetDraw. The findings reveal that the committee's communication network forms a centralized pattern, with the Person-in-Charge and the Executive Chair serving as dominant actors (degree centrality = 1.000; betweenness = 29.447). Division coordinators function as secondary brokers bridging communication between the Executive Board and operational members. An open and egalitarian communication pattern, supported by a collective deliberation system and multi-platform digital media, effectively reinforces both intra-division and inter-division solidarity simultaneously. These findings affirm that the effectiveness of internal communication depends not solely on hierarchical structure, but on the quality of relationships and the openness of information channels within the organization.

Abstract

This study aims to analyze the communication network structure in the Khayangan Festival using the Social Network Analysis (SNA) approach. The study used a quantitative method by utilizing data on communication relationships between involved actors, both internal and external to the festival organizer. Data were analyzed using UCINET and NetDraw software by measuring Degree Centrality, Betweenness Centrality, Closeness Centrality, Eigenvector Centrality, and network density. The results showed that the communication network formed had a centralized pattern, where communication and coordination flows were concentrated in several key actors. Mas Arslan emerged as the most central actor with the highest scores on all centrality indicators, indicating his role as a coordination center, information connector, and the most influential actor in the network. Density analysis showed a relatively dense network with high interaction intensity between stakeholders. In addition, the involvement of the community, sponsors, media partners, and local influencers acted as weak ties that expanded the reach of information and strengthened the event's branding. These findings indicate that the success of the Khayangan Festival was supported by an integrated communication network structure and effective management of information flows. This study provides practical implications for event management in designing network-based communication strategies to improve the effectiveness of event coordination and promotion.
