Abstract

Patient segmentation based on perceptions of service quality is a crucial step in improving patient experiences, optimizing resources, and enhancing healthcare service quality. However, understanding patients' needs and priorities in depth poses a challenge, particularly for hospitals serving populations with diverse demographic backgrounds. This study aims to cluster patients in a private hospital in Jambi City based on their perceptions of service quality using the K-Means algorithm. Data were collected from a 2022-2023 survey, covering patient demographics and perceptions of service quality. The data were processed through preprocessing steps, including missing value imputation, normalization, and encoding. The optimal number of clusters was determined using the Elbow and Silhouette Score methods. The results revealed three main clusters with distinct characteristics. The first cluster (34.29%) includes patients prioritizing service speed and procedural ease. The second cluster (46.12%) consists of patients who emphasize staff competence and cost fairness as their main priorities. The third cluster (19.59%) comprises patients with higher educational backgrounds who are more critical of facility quality and complaint handling. Evaluation using the Davies-Bouldin index demonstrated good cluster separation (score -0.645). This study concludes that patient segmentation based on perceptions of service quality can serve as a foundation for strategic decision-making to improve hospital service quality. Recommendations for future research include applying other algorithms such as DBSCAN, integrating sentiment analysis, and employing a hybrid approach to predict patient needs. These approaches are expected to provide a deeper understanding and more effective personalization of patient care.

Abstract

Education in Indonesia faces challenges in adopting modern technology, particularly in developing effective and engaging learning media. Teachers in the Cross-School Learning Community of Cluster II Anggrek in Jambi City still use conventional methods that are less adaptive to student needs. The utilization of AI technology such as Gamma AI can help create more efficient, innovative, and interactive learning media. The training was carried out systematically with four main modules: Introduction to Gamma AI, Creating Presentations, Tips and Tricks, and Evaluation and Application. The methods used included demonstrations, hands-on practice, interactive discussions, and evaluation of training outcomes. The activity involved 30 teacher participants from the community and was conducted on July 16, 2024, at the SD Negeri 96 Kota Jambi hall. This training successfully improved teachers' competencies in utilizing Gamma AI to create more engaging and interactive learning media. Teachers were able to save time in creating materials, use data for personalized learning, and enhance student engagement through AI-based content. The main output of the activity was the improvement of learning quality in schools within the community and the strengthening of teachers' digital competencies.

Abstract

REST APIs are the backbone of data communication in the Internet of Things (IoT)-based edge computing ecosystem because they are lightweight and flexible. However, the REST architecture's openness and the edge devices' limited resources give rise to security challenges such as MITM, spoofing, and replay attacks. This study aims to identify the key challenges of REST API security in IoT edge environments, evaluate the limitations of conventional solutions such as TLS and RSA/ECDSA algorithms, and explore the potential of Post-Quantum Signature-based digital authentication approaches (PQS). Through a comprehensive narrative literature review of 43 peer-reviewed publications (2020-2025), this research reveals two key findings: the results show that TLS generates significant overhead in memory and energy, while classical algorithms do not resist quantum threats. PQS schemes such as Falcon and Dilithium have proven more efficient and secure in limited devices. The study concludes that PQS-based lightweight authentication approaches have strong prospects for implementation in future REST API gateway architectures, particularly in supporting electronic-based governance systems (SPBEs).

Abstract

The great influence of technological developments on many aspects of life, among others, is seen in major changes in economic, social, and political processes, and even the world of education. As experienced by the College of XX, an organization engaged in the world of education. The implementation of information technology products such as applications has been carried out, but it was found that during the development period until now, the College of XX has never measured the level of organizational maturity in the software development process, so the organization cannot know what system performance is like, and what kind of feedback from users include students, lecturers, education staff on the performance of the system they have. Therefore, it is necessary to measure the level of organizational maturity in the software development process using the CMMI-Dev method. Based on the 22 process areas offered by CMMI-Dev, then adjustments are made to the process area with the system that is owned, the process area in question is Product Integration (PI) or Product Integration and Validation (VAL) or Validation. After conducting the Gap Analysis, it was found that the maturity level (maturity) is 3.5 with a nominal gap value of 0.5 and the percentage gap value of 50% is the lowest Gap, it is concluded that the organizational maturity level is currently at level 2. This means that the process has been planned and carried out in accordance with existing policies, and the human resources employed are skilled in their fields and have other adequate resources. However, in its application, there are still domains that must be improved and improved in order to reach the maximum level. It is recommended to implement the SOP and always evaluate whether the process has behaved consistently and stably.
