The method used was evaluative with the CIPP model (Context, Input, Process, Product), involving observation, interviews, and documentation. The activity was carried out once a week through stages of rhythm introduction, basic movements, body coordination, and simple dance sequences. The results showed that more than 80% of the children experienced improvement in aspects of balance, movement coordination, agility, and large muscle control. In addition, the activity also enhanced children's self-confidence, courage, and social interaction. Therefore, the Janger dance is proven to be effective as a gross motor stimulation and is suitable to be used as a culturally based learning strategy in early childhood education.

This study discusses the introduction of digital signature patterns using the Backpropagation method on Artificial Neural Network (JST) to identify a person's characteristics and potential. The increasing use of digital identities demands a verification system that is more secure, accurate, and adaptive to the variations of each individual's signature. The main problem faced in the signature recognition system is the low level of accuracy when the visual features of the signature have similarities between users, both in terms of shape, size, and stroke pressure. In addition, variations of signatures made by the same individual are also a challenge in the identification process. As a solution, this study implements Principal Component Analysis (PCA) to extract important features from the signature image before the training process using JST. PCA is used to reduce the data dimension so that the learning process becomes more efficient and optimal. A total of 80 signature images were used in this study, consisting of 60 training data and 20 test data. The results showed that the system was able to achieve an accuracy level of 92.5%. These findings prove that the combination of PCA and JST methods is effective in recognizing digital signature patterns and has the potential to be applied to digital security-based biometric identification systems.

This study examines the crisis communication strategies of the JKT48 Operational Team (JOT) following the 2025 “No Encore” incident, which emerged after the viral circulation of an inappropriate photo involving the group’s General Manager and escalated into a major reputational crisis. The controversy triggered strong fan backlash and culminated in the symbolic withdrawal of support during the Full House 2025 concert. Using a qualitative case study approach, this research analyzes organizational responses through interviews with fans, observations of social media interactions, and documentation of official statements. Data were interpreted using thematic analysis and compared with the principles of the Situational Crisis Communication Theory (SCCT). The findings show that JOT’s initial clarification was perceived as slow and insufficient, contributing to heightened dissatisfaction and crisis escalation. However, the second clarification and the introduction of FanSpace, a structured two-way dialogue forum, marked a shift toward more transparent and participatory communication. Fan responses indicate that FanSpace helped reduce tensions and demonstrated managerial willingness to listen, though full trust recovery requires consistent follow-up actions. This study highlights the importance of speed, openness, and dialogic engagement in crisis communication within fan-based entertainment industries. The implications emphasize that organizations must adopt adaptive, audience-centered communication strategies to rebuild legitimacy and restore public trust after preventable crises.
