Abstract

Stress is a psychological condition that requires proper treatment due to its potential long-term effects on health and cognitive faculties. This is particularly pertinent when considering pre- and early-school-age children, where stress can yield a range of adverse effects. Furthermore, detection in children requires a particular approach different from adults because of their physical and cognitive limitations. Traditional approaches, such as psychological assessments or the measurement of biosignal parameters prove ineffective in this context. Speech is also one of the approaches used to detect stress without causing discomfort to the subject and does not require prerequisites for a certain level of cognitive ability. Therefore, this study introduced a hybrid deep learning approach using supervised and unsupervised learning in a stress detection model. The model predicted the stress state of the subject and provided positional data point analysis in the form of a cluster map to obtain information on the degree using CNN and GSOM algorithms. The results showed an average accuracy and F1 score of 94.7% and 95%, using the children's voice dataset. To compare with the state-of-the-art, model were tested with the open-source DAIC Woz dataset and obtained average accuracy and F1 scores of 89% and 88%. The cluster map generated by GSOM further underscored the discerning capability in identifying stress and quantifying the degree experienced by the subjects, based on their speech patterns

Abstract

Digital images can experience various disturbances in acquisition and storage, one of which is a disturbance indicated by damage to certain areas of the image field and causes the loss of some of the information represented by the image. One of the ways to restore an image experiencing disturbances like this is with image completion technology. Image completion is an image restoration technology capable of filling in or completing missing or corrupted parts of an image. Various methods have been developed for this image completion, starting from those based on basic image processing to the latest relying on artificial intelligence algorithms. This study aims to develop and implement an image completion model based on deep learning with the transfer learning method from the completion.net architecture. Using the Facesrub training dataset consisting of a collection of unique facial photos allows the model to understand facial attributes better. Compared to conventional image completion based on image patches, the method developed in this study can perform image filling in image gaps with more realistic results. Based on visual tests conducted on respondents, the results obtained enable respondents to understand all the information represented by the restored image, similar to the original image.

Abstract

The community services carried out are a service program to support government programs in increasing the competitiveness of MSMEs so that they can compete in today's very tight competitive situation. MSMEs in 3T areas (disadvantaged, frontier, outermost) face much more complex problems than those in relatively more developed areas. Partners in this service activity are the MSME beauty salon HNB Salon & SPA located in Nabire Regency, Central Papua. Based on the analysis carried out by the service team, partners experience problems related to the service sales process and also management, especially in terms of customer relationship management and management of marketing activities, then to help MSME partner, the service team will support the use of technology in administering the services provided at the salon in the form of salon service applications. Additionally, increasing human resource capabilities is also very much needed, especially in using various technological equipment, both hardware and software, to support salon operations. Finally, the service team also provides training on using social media to carry out digital marketing to MSME staff. Based on the evaluation of the material for the training activities, excellent results were obtained, and the partners stated that they were very helped by the material and program that the service team had provided.

Abstract

The detection and recognition of traffic signs are crucial components of advanced driving assistance systems (ADAS) that enhance road safety. Current traffic sign detection and recognition model technology is proficient in identifying and interpreting traffic signs. However, for accurate detection and recognition, the traffic sign in the image must be of a certain minimum pixel size or distance from the driver's sight line for proper detection. The ADAS system should be capable of detecting and recognizing road traffic signs from a considerable distance as they come into the driver's line of vision. The higher the vehicle speed, the greater the distance required for the sign to be detected and recognized, allowing the driver sufficient time to react according to the sign's meaning. Addressing these challenges, this research proposes an enhanced version of the single shot detector (SSD) algorithm, commonly used in object detection, to improve the algorithm's ability to detect small objects. The proposed method involves adding an auxiliary layer module to the original SSD architecture to increase the feature map resolution and expand the conventional layer's receptive space. With the Enhanced SSD algorithm, the detection capability of the SSD can be significantly enhanced in terms of accuracy. The limitations of this study are related to the influence of occlusion and clutter, which might affect the performance of object detection, especially for small objects, which are more susceptible to being influenced by various factors. The research results demonstrate that Enhanced SSD improves object detection accuracy compared to the original SSD, with a mean average precision (mAP) of 97.87 compared to 95.35 for detecting 21 traffic signs in Indonesia.

Abstract

Pandemi Covid-19 telah menghasilkan model pembelajaran inovatif di sekolah dari tatap muka atau luar jaringan (luring) berubah online atau dalam jaringan (daring). Guru dan siswa mengalami kendala serta keterbatasan dalam interaksi belajar-mengajar di sekolah sehingga dapat mereduksi kualitas pembelajaran. Untuk mengatasi permasalahan tersebut dibutuhkan workshop pemanfaatan media interaktif Live Worksheets dan E-Quiz. Berdasarkan interview bersama kepala sekolah di Sekolah Menengah Atas Frater Makassar diketahui informasi bahwa beberapa guru belum memiliki kemampuan teknologi dan masih memiliki keterbatasan perangkat sehingga siswa kurang termotivasi belajar serta kurang kreativitas dalam penggunaan aplikasi online di masa pandemi. Metode workshop meliputi penjelasan materi, pemberian tugas, pembahasan tugas, penilaian tugas dan evaluasi. Tujuan workshop adalah meningkatkan kompetensi guru dalam melaksanakan tugas di sekolah. Hasil workshop  menunjukkan bahwa sebanyak 70% peserta telah mampu mengunakan Live Worksheets dengan baik, 90% peserta telah mampu menggunakan Kahoots! dengan sangat baik, 85% peserta telah mampu menggunakan Quizwhizzerr dengan sangat baik, dan 80% peserta telah mampu menggunakan Rumah Belajar dengan baik. Workshop Peningkatan Kompetensi Guru telah mampu memberikan pemahaman dalam menerapkan metode belajar-mengajar yang membantu meningkatkan kinerja belajar siswa.
