Abstract

This study investigates three types of emission families in Hidden Markov Models (HMMs) for reconstructing Bedoyo Majapahit dance motion captured using a markerless system. The recorded skeleton data, consisting of 3,341 frames and 33 joints per frame, were normalized and reduced into a 30-dimensional latent space using Principal Component Analysis (PCA). Three emission variants were evaluated: single-Gaussian HMM, Gaussian-mixture HMM (GMM-HMM), and Multinomial HMM. The evaluation employed a tri-metric scheme consisting of Mean Squared Error (MSE), Dynamic Time Warping (DTW), and Fréchet distance to measure reconstruction fidelity. The experimental results showed that GMM-HMM consistently outperformed the other two models, achieving the lowest reconstruction error and the closest alignment to the original temporal and geometric motion profiles. The Gaussian HMM demonstrated moderate performance but tended to underestimate motion amplitude, while the Multinomial HMM produced the weakest results due to the discretization of continuous pose data. These findings indicate that multimodal emission functions provide a more expressive representation for continuous dance motion. The study highlights the suitability of GMM-HMM for traditional dance preservation through computational modeling and contributes to the development of digital motion archiving for cultural heritage.

Abstract

This community service activity aims to enhance the skills and knowledge of Vocational High School (SMK) students in the field of Information Technology. The program also provides learning and practical experience for university students through direct involvement in the empowerment activities for SMK students at the Computer Science Society community, Puncak CBD Apartment No. 8D, Surabaya. The location and characteristics of the community offer significant potential for broadening students’ insights and increasing their knowledge of technological developments. The activity focuses on training participants to create simple web pages using HTML and CSS programming languages. The results indicate an improvement in students’ understanding of HTML and CSS. In addition, participants showed high enthusiasm and were able to apply the material in creating websites. This enthusiasm emerged because their schools had not previously provided instruction in HTML and CSS, making this training a valuable opportunity to gain new and relevant knowledge.
