Public transportation, with Transjakarta as its main pillar, requires a deep understanding of customer behavior to improve service quality and maintain loyalty. This study aims to segment Transjakarta customers using data mining techniques, specifically the K-Means Clustering algorithm, based on the RFM (Recency, Frequency, Monetary/Value) behavioral model. 37,900 rows of raw transaction data were processed into a clean database, resulting in 1,917 unique customers for analysis. The RFM metrics were then normalized using Min-Max Scaler. The optimal number of clusters was evaluated using the Elbow Curve and Silhouette Score Methods, which led to the determination of k = 4 clusters. The segmentation results identified four customer groups requiring specific strategies: Cluster 3 (Champions) with high R, F, and V (requiring rewards and retention); Cluster 0 (Active, Low Value) with high R and F but low V (requiring upsells and cross-sells); Cluster 1 (Potential/At-Risk); and Cluster 2 (Dormant/Lost). Preliminary analysis (EDA) showed that nearly half of customers (49.3%) used Bank DKI cards, dominated by the productive age group (25–45 years old), with the Rusun Kapuk Muara–Penjaringan route being the busiest. The main managerial recommendation is to strengthen the partnership with Bank DKI and optimize services in this busy corridor.

The increasing number of motorcycle thefts in various regions indicates that conventional security systems are not yet fully effective in protecting vehicles, necessitating new technology-based innovations. This study discusses the planning and implementation of a motorcycle security system utilizing Radio-Frequency Identification (RFID) technology as a more responsive and modern solution. The system is designed using a passive RFID tag placed on the motorcycle key, an RFID reader integrated with the motorcycle unit, and an Arduino microcontroller that functions to control the ignition system. With this combination, the motorcycle can only be activated if the appropriate tag is detected, while access attempts using an invalid tag or the loss of the tag will automatically disconnect the ignition system. Test results announced that tag recognition can be done very quickly, in less than a second, so as not to disrupt the user's comfort when starting the vehicle. In addition, this system is able to maintain consistent performance by providing an automatic response that supports advanced security. The implementation of this plan is expected to reduce motorcycle theft by providing an additional layer of security that is more difficult to penetrate than a manual key system. From the user's perspective, this technology remains practical because it does not require complicated procedures in its operation, simply by ensuring the appropriate RFID tag is attached to the motorcycle key. Overall, this research confirms that the application of Arduino microcontroller-based RFID technology can be an alternative, inexpensive, and applicable security system in everyday life. It is hoped that this system will not only improve protection for vehicle owners but also serve as a benchmark for the development of more sophisticated transportation security technologies in the future. Implementation of this system is expected to reduce motorcycle theft and provide a greater sense of security for vehicle owners.

This research explores cultural preservation strategies through the development of the tourism sector, using the Surakarta Palace as a case study. The Surakarta Palace, a cultural heritage site in Central Java with significant historical and cultural value, plays a vital role in preserving Javanese traditions while contributing to regional tourism growth. This study adopts a descriptive qualitative method with data collected through observation, interviews, and documentation. The findings reveal that the Surakarta Palace actively preserves culture through various initiatives such as organizing traditional ceremonies, staging classical Javanese art performances (like gamelan and wayang), and managing museums that house historical artifacts and royal collections. These strategies serve not only to maintain cultural continuity but also to increase the attractiveness of the palace as a cultural tourism destination. Despite these efforts, several challenges remain. These include limited financial resources, minimal use of digital media for promotion, and the lack of public awareness—especially among younger generations—regarding the importance of cultural heritage. To address these challenges, the study emphasizes the need for integrated collaboration between the government, the Surakarta Palace institution, and the surrounding community. Strengthening digital-based promotional strategies and educational outreach is also considered essential to increase public engagement and sustainable tourism impact. In conclusion, the Surakarta Palace serves as a strategic model for cultural preservation within the tourism framework. By improving stakeholder cooperation and adapting to technological advances, cultural heritage can be preserved effectively while supporting local economic development through tourism. Therefore, cultural preservation and tourism development should be positioned as complementary efforts, where the sustainability of both depends on strategic planning, inclusive participation, and adaptive innovation in facing the dynamic demands of modern tourism.
