Abstract

Cataract is a condition that causes clouding of the lens of the eye and is a leading cause of blindness, including in Indonesia. Cataract diagnosis is often inconsistent between ophthalmologists due to personal experience. This research proposes a Support Vector Machine (SVM) based classification system and Harmony Search metaheuristic algorithm to optimize the weight vector 'w' on the SVM hyperplane as a supporting tool for cataract diagnosis. The research data comes from Kaggle which includes normal eye fundus images and cataracts with mild-moderate and severe levels. The research stages include image conversion from RGB to Grayscale, image enhancement with Histogram Equalization and GLCE, and feature extraction using GLCM and Haar Wavelet Transform, and unbalanced data is balanced by the SMOTEENN method. The results showed that Harmony Search successfully improved SVM accuracy compared to Conventional SVM using Gradient Descent. Accuracy increased by 18% from 0.53 to 0.71 on unbalanced data, and by 13% from 0.67 to 0.80 on balanced data. In addition, Harmony Search can improve computational time efficiency due to its ability to explore space globally.

Abstract

The SIMAPA system is a system for monitoring children's activities and development which is implemented at KB-TK Agripina Surabaya. The SIMAPA system has been designed using system development, namely SDLC (System Development Life Cycle). The system can be declared valid and by what is expected if testing has been carried out. An application can be tested using collaborative alpha and beta testing using the black box method. Alpha testing is carried out to see whether all systems can run well and is carried out by the system manufacturer. Meanwhile, in beta testing, the party who will assess the system is the user or people who are not involved in creating the system. This testing is carried out by distributing questionnaires to several users to assess the application that has been built. The questionnaire contains questions about the system being built so that it can be concluded whether the application is by the objectives. The results of the Beta test with 6 questions about the system obtained good results with an average score of 92%. so that the system built is by what is expected.

Abstract

Education in the 21st century demands technology support, in which gameful media, such as educational games, can provide. Providing this support also requires the media to accommodate the different needs of the players, which can be identified by classifying the players’ type using HEXAD typology. However, the effect of HEXAD type classification on players’ experience in gameful media is still vague. This study aims to adress this vagueness by exploring the implementation of HEXAD in a more systemic and fine-grained manner using a playtest of an educational role-playing game. We measured the playtesters’ gameplay and learning experiences (n = 60) through a questionnaire developed based on HEXAD scale, GUESS, and EGameFlow. We also measured the correlation between the playtesters’ HEXAD types and their gameplay and learning experiences. Our analysis of the correlations uncovers exciting findings, including that the “achiever” type strongly appreciates playability features and that playability is among the essential gameplay factors for HEXAD types. We also propose design principles that can guide future research and development of the media.

Abstract

The Indonesian Sign Language System (SIBI) is an essential means of communication for the deaf and speech-impaired community in Indonesia. However, the limited public understanding of SIBI often hinders effective communication. This study develops a real-time SIBI sign recognition model to facilitate effective communication for the deaf and speech-impaired in Indonesia. The proposed method integrates a hybrid CNN-LSTM model to process the spatial and temporal information from the data. The study evaluates the model's performance on 25 types of SIBI signs. The dataset used consists of image sequences captured in real-time. Training is conducted with various parameters, including batch size, learning rate, and epochs. Model evaluation is carried out using accuracy, precision, recall, and f1-score metrics. The training and validation results show an increase in accuracy with the number of epochs: 87% at 10 epochs, 93% at 25 epochs, and 100% at 50 epochs. In real-time detection tests, the model with the image sequence dataset accurately detected SIBI signs in environments and with objects consistent with the dataset. The real-time detection program generates SIBI sign predictions in text form and sentences. The output of this research is efficient and accurate SIBI sign recognition technology. This research is expected to facilitate more effective communication for the deaf and speech-impaired community in Indonesia.

Abstract

Pneumonia is a type of respiratory infection in the respiratory tract that is often caused by viruses or bacteria. Poor air quality in Jakarta's urban areas increases people's risk of developing pneumonia, acute respiratory infections (ARI), and asthma. 2019 showed that more than 740,180 children under the age of 5 died from pneumonia cases, about 14% of all early childhood deaths. In overcoming pneumonia, medical researchers have conducted many studies related to the problem of early diagnosis of pneumonia. One of the techniques to detect pneumonia is through chest x-rays that have been developed for classification. Vision Transformer (ViT) is one of the Deep Learning architectures developed specifically for image processing. The purpose of this study is to implement the classification task of pneumonia with ViT which is expected to help detect pneumonia early so that it can be treated faster and better. The results of the study show that the ViT model has good performance after applying several variations of augmentation, and is stable both in training and testing. at a small Learning Rate of 0.00001, it produces 80% accuracy for the case of pneumonia disease classification through Chest X-Ray Images.

Abstract

The main objectives are to identify emotion patterns hidden in K-Pop music based on audio features extracted from the Spotify API and to build an emotion classification model that can predict the emotions of K-Pop songs.In this approach, the K-Means algorithm is used to cluster K-Pop songs based on audio features such as energy, valence, tempo, danceability, and speechiness. The clustering results reveal several main groups that represent variations in musical characteristics and emotions. Next, the C4.5 algorithm was used to build an emotion classification model based on the clustering results. The C4.5 model showed high performance with accuracy reaching 99.48% on a 90:10 dataset split, 99.21% on an 80:20 split, and 98.95% on a 70:30 split.The Streamlit application was developed to visualize emotion predictions from K-Pop songs with a web-based user interface. In addition, Ngrok was used to provide remote access to this application, allowing users to test and use the application remotely.The results of this study show that the combination of K-Means and C4.5 can effectively cluster and classify emotions in K-Pop music, providing valuable insights into the musical characteristics that influence emotions. This application has the potential to be used in further analysis, development of intelligent features in music applications, and improvement of user experience in listening to K-Pop music.

Abstract

Pencarian dokumen skripsi pada repositori digital umumnya masih terbatas pada pencocokan kata kunci sehingga sering menghasilkan temuan yang kurang relevan. Berdasarkan permasalahan tersebut, penelitian ini bertujuan untuk membangun sistem pencarian semantik dokumen skripsi dalam format PDF dengan memanfaatkan Sentence-BERT (SBERT) dan metode Cosine Similarity yang dipadukan dengan ontologi untuk memperkaya pemahaman makna query. Sistem ini dirancang agar mampu memahami maksud pengguna secara lebih mendalam, baik ketika query diberikan dalam bentuk kata, frasa, kalimat, maupun paragraf. Tahapan penelitian meliputi ekstraksi teks dari dokumen PDF, preprocessing, tokenisasi WordPiece, serta pembentukan vektor representasi kalimat menggunakan SBERT. Skor relevansi dihitung dengan kombinasi bobot cosine similarity (0,7) dan ontologi (0,3) sehingga sistem dapat menampilkan dokumen dengan makna paling mendekati query. Hasil pengujian menunjukkan bahwa sistem mampu memberikan hasil pencarian yang relevan dengan nilai Mean Reciprocal Rank (MRR) konsisten sebesar 1.0 pada semua jenis query. Nilai Precision rata-rata mencapai 0,80 dan Recall rata-rata sebesar 0,92. Perbandingan dengan metode Keyword Matching menunjukkan bahwa metode semantik lebih unggul dengan Precision rata-rata 0,88 dan Recall 0,65 dibandingkan keyword yang hanya mencapai Precision 0,24 dan Recall 0,12. Temuan ini membuktikan bahwa sistem semantik efektif dalam menempatkan dokumen paling relevan di peringkat teratas dan lebih unggul dibandingkan pencarian berbasis kata kunci, meskipun cakupan hasil masih perlu ditingkatkan melalui pengayaan ontologi dan perluasan dataset.
