Abstract

The inspection of packaging defects is a crucial aspect of maintaining the quality of industrial production, especially in the case of boxed products. This study introduces a novel approach for detecting physical defects in product packaging boxes by integrating image processing with deep learning, specifically transfer learning with two images as an input. The proposed method utilizes both top view and side view images of the packaging to determine its condition, a significant departure from the conventional single image input. Our approach incorporates 16 pre-trained model variants from EfficientNetV2, MobileNetV3, and ResNetV2 for transfer learning as feature extractors. The experimental findings demonstrate that the best model that leverages EfficientNetV2 variant achieves 100% accuracy and F1 score in terms of classification performance. However, the most optimal model in terms of classification performance and inference speed was the one that leveraged ResNetV2 variant. This model scored 95% accuracy and 95.24% F1 score, with an inference speed of 91 ms per prediction.

Abstract

Computerized embroidery sewing is an innovation that's relatively easy to learn and produces embroidered objects on fabric quickly and in a marketable way. This machine is ideal for seniors who still want to be productive and increase their income in their later years without having to spend too much time and effort learning to use it. Consequently, a community of seniors around Kranggan, Bekasi, who were interested in computerized embroidery sewing training was chosen. Before the training, participants were given a questionnaire to assess their prior knowledge of computerized embroidery techniques on fabric. It turned out that almost all participants had never used such a machine. As a result, during the training, when they gained new knowledge about using the embroidery machine, they were very enthusiastic about practicing and even suggested having more training sessions in the future to enhance their skills in embroidering prayer cloths and bags

Abstract

The printing industry is undergoing a significant digital transformation to overcome traditional operational challenges. Conventional printing services often face problems such as long customer queues, miscommunication regarding technical specifications, and high dependency on staff, leading to operational inefficiencies. To address these issues, a self-service kiosk prototype was designed using the Design Thinking method, aimed at automating and simplifying the ordering process. This study conducts a usability analysis of the kiosk prototype to evaluate its effectiveness, efficiency, and user satisfaction. The method used is Usability Testing, employing performance measurement techniques to assess effectiveness and efficiency, and the Questionnaire for User Interface Satisfaction (QUIS) to evaluate user satisfaction. The results of the Usability Testing indicate that the self-service kiosk prototype achieves a high level of effectiveness and efficiency, meeting the established standards. Furthermore, the analysis of user satisfaction through the QUIS questionnaire shows an optimal outcome, suggesting that the designed interface is well-received by users.

Abstract

This study investigates the effect of gum arabic composition on the solid content of organic ink made from sappan wood (Caesalpinia sappan) as a natural dye. The study uses a quantitative method with an experimental approach. The main focus of this research is the solid content test, which is important for determining the quality and durability of organic inks. Variations of gum arabic were used as a binder in the ink formulation, with the tests conducted using screen printing on cotton combed fabric. The results indicate that the lower the composition of gum arabic used, the higher the solid content obtained. The ink with the lowest gum arabic composition (5 grams) produced the highest solid content at 78.79%, compared to 75.00% for 10 grams and 60.00% for 15 grams of gum arabic. Additionally, physical characteristics such as color intensity and viscosity were also influenced by the solid content, with darker colors and thicker textures observed as the solid content increased. These findings contribute to the development of more eco-friendly organic inks with improved stability and performance, supporting the sustainability trend in the printing industry.
