Abstract

The management of libraries in Indonesia is generally still done manually, leading to several issues such as inaccurate book inventory data and unclear transaction processes. The aim of this research is to design a web-based library information system using the User Experience (UX) concept, which will provide ease of use for users by focusing on effectiveness, efficiency, and satisfaction. This concept involves four stages: analysis, design, implementation, and evaluation. During the analysis stage, data collection is carried out through observation, interviews, and the distribution of questionnaires to understand the needs of the members. Next, the system is designed to meet the needs of both the members and the management. After that, usability testing is conducted to evaluate the effectiveness, efficiency, and user satisfaction with the system. The testing involved 15 members and library staff. The results showed that in terms of effectiveness, all tasks were above the average completion rate. In terms of efficiency, the product usage time was satisfactory, and in terms of satisfaction, using the UEQ (User Experience Questionnaire) showed good to very good results. Therefore, the library system can be used by library members to support their library activities.

Abstract

In mathematics lessons in elementary schools, the learning methods used by teachers are often still conventional, which can reduce students' interest in learning, especially at the elementary level, making them feel that math is not fun. The problem faced by the 5th grade teacher of UPT SD Negeri 192 Gresik is the difficulty of students in understanding the material of geometry, especially the formula for calculating the area and volume of various geometry. The limited learning media used, especially in the material of geometry, causes students to feel bored and have difficulty understanding the material. This research aims to design and produce an educational game. which can be used as a student learning tool related to geometry. In this research, using Game Development Life Cycle (GDLC) as the method used. The pretest and posttest results for the Solid Shapes Explorer game tested showed that the average pretest score of 20 students was 63.5, while for the posttest, the average student score reached 82. From the calculation results, it can be seen that the average posttest score shows an increase compared to the pretest score, with a difference of about 18.5 It can be stated that the use of learning through the Solid Shapes Explorer game has succeeded in improving students' understanding of geometry material.

Abstract

Abstract. MI Al-Ihsan Sidoarjo is a madrasa school located in Sidoarjo, East Java. However, the teachers there still rely on textbooks and question sheets for their teaching methods, and do not have projectors to use PowerPoint as another teaching method, which often causes students to not understand the essence of the lessons being delivered, due to the detailed delivery of the material. With these considerations in mind, the researcher solved the problem at MI Al-Ihsan by creating an interactive learning media application called "Verb-ng for Fun" specifically for English lessons which can be accessed using a computer in the lab, so that it can be used by MI English teachers. Al-Ihsan as a supporter for delivering lesson material. In designing it, the researcher studied the English teacher at MI Al-Ihsan and used the material in the textbook as application design material. The researcher aims to use the ADDIE method as a reference for designing interactive learning media applications that will be created. It is hoped that the design of this application can be used to improve students' understanding of English lessons.

Abstract

Localizing objects from an image has been a vital part in autonomous driving since object localization performance directly correlate with the safety of the passenger. Robust and accurate object localization that can adapt to any driving environment has always been improved to ensure a safe and reliable system. In this work, we propose CBNet, a two-stage instance segmentation network for an autonomous driving environment. The network leverages a powerful transformer network as the feature extractor to improve performance. In addition, our proposed network utilizes a cascade design for both the object proposal network and the region-of-interests classifier. The cascade design addresses the issue of degrading detections over a high detection threshold. Moreover, we implement shape and edge-aware losses for the segmentation mask and end-to-end knowledge distillation strategy during training to improve the robustness of the network in extreme conditions. Our proposed network achieves 6.5 AP and 5.7 mIoU improvement from the prior methods in Cityscapes driving dataset. Furthermore, we evaluate our network in Foggy Cityscapes dataset to ensure the robustness of our network in extreme conditions. CBNet is able to improve the performance of prior methods by 7.7 AP and 6.7 mIoU in Foggy Cityscapes dataset.

Abstract

Indonesia, home to the world's largest Muslim population, holds significant potential for developing a Sharia-based economy. However, the Sharia financial literacy index among Indonesian society remains low, standing at just 8.93% in 2019. This is attributed to a lack of financial management skills within the community. With rapid technological advancements, access to information, including Sharia finance, has become easier, yet it also brings about challenges in finding relevant information. To address this, a recommendation system needs to be established to offer guidance on Sharia financial matters. The application of content-based filtering, utilizing TF-IDF weighting and cosine similarity calculations, aids in providing suitable content recommendations. Upon successful implementation as a cloud web server, this system is seamlessly integrated into a mobile application. The article recommendation system achieves an average precision of 68%, recall of 100%, F1-score of 80%, and accuracy of 73%. Similarly, the video recommendation system attains a precision of 86%, recall of 100%, F1-score of 92%, and accuracy of 91%.
