A Real-Time Helmet Detection System Based on YOLOv8 to Support Traffic Law Enforcement

Tiara Puspita — 2025-06-30

Helmet use is a critical safety measure for motorcycle riders, yet non-compliance remains high in Indonesia. This study introduces a real-time helmet detection system using the YOLOv8 architecture, deployed on Android devices with the Kotlin programming language. A dataset of 1,197 digital images was collected and annotated using Roboflow Annotate, containing two classes: helmet users (True) and non-users (False). To improve model generalization, data augmentation techniques such as rotation and shear were applied. The model was trained using the pretrained yolov8n.pt weights and evaluated based on mAP and Intersection over Union (IoU). During training, the model achieved a mAP50 of 98% and a mAP50–95 of 59.6%. In testing, the mAP50 reached 98.3% and mAP50–95 reached 61%, with an average IoU of 0.73. The trained model was then converted into TensorFlow Lite format and integrated into an Android application. Real-time testing showed a detection accuracy of 93.3%. These results demonstrate that YOLOv8 is effective for mobile-based real-time helmet detection and has strong potential to support traffic law enforcement systems, especially in urban environments where manual monitoring is inefficient. The system contributes to enhancing public safety through smart technology integration.

Hery Julianto — 2025-06-30

This study aims to analyze the influence of green accounting, company performance, and carbon emission disclosure on firm value, with gender diversity on the board of directors as a moderating variable in consumer goods companies listed on the Indonesia Stock Exchange from 2020 to 2023. Employing a quantitative causal-comparative research design, secondary data were collected from annual reports, sustainability reports, and environmental performance rating documents (PROPER). Statistical analyses including descriptive statistics, classical assumption tests, multiple linear regression, and moderated regression analysis were conducted using SPSS 25. The results reveal that green accounting, company performance, and carbon emission disclosure have significant positive effects on firm value. Moreover, gender diversity on the board significantly moderates these relationships, though with varying effects: it weakens the positive impact of green accounting on firm value but strengthens the effects of company performance and carbon emission disclosure. These findings suggest that while environmental accounting practices and corporate performance are critical in enhancing firm value, the role of gender diversity introduces complex dynamics in corporate governance influencing sustainability outcomes.

Faisal Manta — 2025-06-30

The turning process in manufacturing is used as the formation of cylindrical components, threads and drilling. ST41 steel has the ability to form, weld and treat, so it is used as a material for tools and automotive components. Insert tools with long life (live time), resistance to wear and high temperatures are better than conventional tools, making the type of insert tool used for various cutting processes. The quality of turning is determined by the selection of cutting parameters that are appropriate to the type of material being cut and the tool used. Lathe parameters are feed rate, cutting speed, deep cut. Feed rate parameters affect process time, surface roughness and tool wear. The use of excessive feed rate causes surface roughness outside tolerance and large tool wear. Therefore, research on ST 41 steel with insert tools to obtain optimal parameters is needed. Research using the experimental study method aims to analyze the effect of tool wear values on changes in feed motion and surface roughness. Turning of ST41 steel on a GUT C0636D X 1000 lathe, CCMT 060204 insert tool, 0.6mm depth cut, 300 rpm cutting speed and feed rate variation of 0.1620, 0.3250, 0.8120 mm/rev. The results of the study measured the tool wear value increasing against feed rate and surface roughness. The highest tool wear value is 0.021 grams, namely with a feed rate variation of 0.8120 mm/rev, a surface roughness of 8.961 μm is obtained. The lowest tool wear value is 0.005 grams, namely with a feed rate of 0.6120 mm/rev, a surface roughness of 5.300 μm is obtained.

Identification of Bisphenol-A (BPA) in Polycarbonate (PC) Baby Bottles in Jayapura, Papua

Andre Anusta Barus — 2025-06-30

Bisphenol-A (BPA) is found in various types of food packaging, such as plastic bottles, paper-based packaging, and the inner lining of canned foods. BPA is widely used in the production of polycarbonate (PC) plastics due to its strength and heat resistance. However, BPA can migrate into food or beverages through physical mechanisms, resulting from the diffusion of loosely bound BPA within the polymer matrix, or through chemical mechanisms triggered by hydrolysis reactions at high temperatures or extreme pH conditions. This study aims to evaluate the migration levels of BPA from polycarbonate (PC) packaging into water at various temperatures using UV-Vis spectrophotometry. The experiment was conducted by adding water into polycarbonate baby bottles at temperatures of 60–100°C, allowing it to sit for 30 minutes before analysis. The test results were compared with the safe BPA consumption limit set by the European Food Safety Authority (EFSA), which is 4 µg/kg body weight per day, as well as the BPOM standard, which establishes a BPA migration limit of 0.6 mg/kg per day. The results showed that BPA was not detected in water that had been in contact with polycarbonate baby bottles at the tested temperatures. Absorbance measurements indicated negative values, suggesting that the detected BPA levels were below the method's detection limit. This indicates that BPA migration is extremely low or undetectable, suggesting that its use under normal conditions can be considered safe.

The Effect of Attachment Styles on Celebrity Worship in K-Pop Fans with Age as a Moderator

Irnawati Jayanti — 2025-06-30

The increasing popularity K-Pop in Indonesia has captured the attention of diverse age groups, especially in adolescents and young adults. Fans’ attachment to K-Pop idols can be understood by the concept of celebrity worship. Celebrity worship consists of three levels; from entertainment social, as the low level, intense personal, as the moderate one, and bordeline pathological, as the highest. Adolescents and young adult had differences in celebrity worship, On the other hand, attachment styles develop from childhood to form attachment patterns that occur when a person reach adulthood. There are four types of attachment style, i.e.: fearful, dismissing, preoccupied, and secure. We believe celebrity worship can be affected by attachment styles in adolescent and young adult K-pop fans. This quantitative study aims to investigate the effect of attachment style on celebrity worship, with age as a moderating variable. The study involved adolescent and young adult K-Pop fans, using the Celebrity Attitude Scale (CAS) and the Attachment Style Questionnaire (ASQ) as measurement tools. Data were analyzed using two-way ANOVA. This study found that age moderates the effect of attachment style on celebrity worship. Dismissing attachment styles influenced the entertainment-social dimension in young adults but not in teenagers. These results highlight the importance of the developmental stage in understanding the effect of attachment style on celebrity worship.
