Abstract

This study analyzes the nonverbal dialogue of the character Tantri in Kamila Andini’s The Seen and Unseen through Roland Barthes’s semiotic framework (denotation, connotation, myth) and Konstantin Stanislavski’s acting system (given circumstances, inner action, physical action). The research focuses on bodily gestures, facial expressions, artistic settings, symbolic properties (such as eggs, children in white shirts, cockfight dance), and ambient soundscapes that signify the transition between the sekala niskala (seen unseen) realms. Primary data include the film itself and key sequences, supported by literature, interviews, and cultural sources on Balinese cosmology. The findings show that the egg serves as a symbolic sequence representing the world and Tantri and Tantra’s twin bond, the cockfight and “chicken dance” metaphorically express the life death tension, children in white shirts represent catur sanak, the unseen siblings who guide Tantra’s departure, physical actions in performance embody genuine emotion without reliance on spoken dialogue. This film situates body language and cultural symbolism as primary narrative instruments for expressing grief and separation.

Abstract

This research develops a cross-lingual sentiment analysis system (RoBERTa-IndoBERT) to monitor public opinion on Bank Indonesia’s 2025 monetary policy from X (Twitter), addressing the scarcity of Indonesian labels and noisy social media text. We introduce a "translate-then-classify" pipeline: Indonesian posts are translated into English, auto-labeled by a mature English RoBERTa model, and these labels are used to fine-tune IndoBERT on the original texts. We compare this cross-lingual (CL) approach, with and without back-translation (BT) augmentation, against a baseline Indo-only model. Performance measured by Accuracy and Macro-F1 indicates the CL pipeline is substantially better than the baseline. The complete model (IndoBERT + CL + BT) yields a Macro-F1 of 98.1%, a 2.8 percentage point (pp) improvement over the baseline (95.3%). Qualitative error analysis corroborates the CL model is more stable, less prone to extreme polarity flips, and better at detecting implicit sentiment. This research demonstrates that a CL auto-labeling pipeline is an efficient and resilient solution for Indonesian sentiment analysis in low-resource scenarios.

Abstract

Water level management in pools and tanks is critical, but sensor accuracy can be compromised by dynamic surface conditions. This research presents the design and implementation of an Internet of Things (IoT) based system for automatically monitoring and controlling water levels. The system utilizes an HY-SRF05 ultrasonic sensor to measure water height and integrates with an automated valve (tap) control mechanism to maintain the level within predefined thresholds. A comparative analysis was initially performed with a Sharp GP2Y0A21YK0F infrared sensor, which was found to be unsuitable for the required short-range measurements. The primary system was then tested under four distinct water surface conditions: calm, wavy, foamy, and foamy-wavy, at target heights of 4 cm, 8 cm, and 12 cm. The system demonstrated high accuracy and responsiveness in all scenarios. A web and mobile application were also developed for real-time monitoring and remote management. This study confirms the robustness of the ultrasonic sensor for reliable water level automation, even in challenging environments.

Abstract

The advancement of artificial intelligence technologies has driven significant innovation in intelligent transportation systems, particularly in autonomous vehicles that require real-time object detection capabilities. This study develops a web-based traffic sign detection system using the YOLOv8 (You Only Look Once version 8) algorithm. The dataset consists of 5,224 annotated images representing 20 classes of traffic signs, collected through direct image acquisition and managed using Roboflow. The preprocessing stage includes resizing all images to 640×640 pixels and applying data augmentation to enhance model generalization. Model training was conducted on Google Colab using an optimal configuration of 50 epochs, a batch size of 32, and a learning rate of 0.001, resulting in a Precision score of 0.9406, a Recall of 0.9395, and an mAP50 of 0.9748. The trained model was integrated into a Flask-based web application to support image, video, and real-time camera detection. The results indicate that the system is capable of detecting traffic signs with high accuracy and strong computational efficiency.

Abstract

This film has two discussions about love and life problems as you want to be like in the movies. Sometimes we wish that falling in love like in the movies is a dream, so we try to fall in love as best for the best ending as well. As in an uncertain life, problems come as if they are never invited at all. Movies can create and present the character of a person in which the movie was made. So watching the film is not only enjoying the story that is told, but at the same time being able to learn how the reactions of the characters in the film are produced. Falling in Love Like In Movies is one example of a film that features characters so that it can be a trigger and reinforcement in a film drama.

Abstract

Digital transformation within government agencies has expanded the number of public-sector digital assets that require continuous cybersecurity protection. However, vulnerability reporting mechanisms in Indonesia remain fragmented, unstandardized, and legally ambiguous, limiting effective collaboration between ethical hackers and government institutions. This study explores the motivations, preferences, and challenges experienced by active vulnerability researchers in participating in government-led Vulnerability Disclosure Programs (VDPs). A descriptive qualitative approach was applied using open- and closed-ended online questionnaires completed by six respondents with proven experience in legal vulnerability reporting. The findings reveal that clear scope definition, transparent rules, timely responses, and legal protection (safe harbour) are the primary factors influencing participation. Although financial incentives are considered beneficial, most participants are willing to report without monetary rewards when non-financial recognition—such as points, badges, or official acknowledgment—is provided. The study also identifies key barriers, including unclear scope, lack of government responsiveness, and concerns regarding legal repercussions. Based on these insights, this work proposes a structured and centralized vulnerability reporting framework tailored for government environments. The proposed model emphasizes clear policies, triage transparency, non-monetary recognition systems, and safe-harbour protections to strengthen national cybersecurity resilience through collaborative public engagement.

Abstract

The agricultural sector in developing regions often faces dual challenges: the lack of systematic harvest data recording and inefficient supply chains dominated by intermediaries. These issues result in suboptimal land productivity management and reduced profit margins for farmers. This study addresses these problems by designing a system based on Client-Server Architecture to digitize harvest records and facilitate direct-to-partner transactions. Utilizing Flutter as the mobile client and Laravel as the server-side API provider backed by PostgreSQL, the system implements a specific Land Productivity Yield (LPY) algorithm to map high-performing cultivation methods. The architecture connects three strategic stakeholders: Farmers, Regional Coordinators, and Industrial Partners. Usability testing using the System Usability Scale (SUS) yielded a score of 79.25, indicating high acceptance among the user demographic. The results demonstrate that the proposed architecture successfully reduces information asymmetry and provides a robust framework for data-driven decision-making in regional agriculture.

Abstract

This systematic literature review examines didactical design in mathematics learning from 2015-2025, analyzing implementation patterns across educational contexts while evaluating key design elements. Following PRISMA guidelines, we analyzed 32 articles from diverse international sources. Results revealed distinct educational level-specific approaches to mathematics instruction, with geometry emerging as the predominant content area. Findings indicate that successful didactical designs align instructional approaches with students’ developmental stages: gamification for elementary arithmetic, Realistic Mathematics Education for junior high geometry, problem-based learning for senior high trigonometry, and Socratic questioning for undergraduate calculus. GeoGebra was identified as the most frequently utilized educational tool, highlighting the significance of dynamic mathematics software. This study contributes to mathematics education by providing evidence-based guidance for didactical design implementation while identifying critical research gaps regarding cross-cultural effectiveness, longitudinal impacts, and technology integration. The geographical concentration of studies suggests a need for more diverse international perspectives to strengthen the generalizability of findings.

Abstract

The growth of the coffee shop industry in Indonesia has caused problems in the table reservation system, which is still done manually, such as long queues, uncertainty of seat availability, and poor service. The purpose of this research is to improve service quality by developing an Android-based mobile application that enables table booking and reservation. Requirement analysis, system design, implementation, testing, and maintenance are the stages of the Waterfall Software Development Life Cycle (SDLC) used. Field observations, interviews with managers, and customer questionnaires are the methods used to obtain research data. The implementation results show that the application is capable of making real-time reservations, providing status notifications, and helping managers monitor table capacity. In addition, testing shows that the system can improve customer satisfaction, speed up the reservation process, and reduce queues. Thus, this research found that optimizing the Waterfall method can produce an application that is stable, organized, and relevant to the needs of the contemporary coffee shop industry.

Abstract

The problem faced by Dina Griya Rias as a wedding organizer service provider is the use of a manual rental system, such as handwritten records, face-to-face communication, and phone calls. This manual process often causes issues like scheduling errors, delayed order confirmations, difficulty monitoring item availability, and limited access to fast and accurate information. Without a digital system, operational efficiency and service quality will remain hindered, reducing customer satisfaction and business competitiveness. This study aims to design and develop a web- and mobile-based rental system for wedding goods and services that can be used by both admins and customers. The system includes real-time item availability monitoring, rental transaction recording, and online booking accessible anytime. Early results show that the system improves rental management efficiency, reduces human error, and provides faster and more convenient services for customers and administrators.
