The dissemination of personal data through digital media has increased significantly alongside the growing use of Quick Response (QR) Codes for various purposes, such as electronic tickets, certificates, and digital identities. Conventional QR Codes are open and can be easily scanned, copied, or manipulated by unauthorized parties. The personal data referred to in this study includes sensitive information such as full name, identity number (NIK/National ID), date of birth, address, phone number, and email address. This research proposes a layered security system that combines the Advanced Encryption Standard (AES) cryptographic algorithm with steganography using the Discrete Cosine Transform (DCT) method. The process begins with encrypting personal data using AES, converting the encrypted result into a QR Code, and embedding the QR Code into a digital image using DCT, hiding it in the image’s frequency domain. The digital images used are of fixed size and formats that preserve visual quality. System evaluation is carried out by testing the visual quality of the stego image, the success rate of QR Code extraction, and the integrity of the encrypted data. The results are expected to conceal sensitive information visually while maintaining its confidentiality, with potential applications in electronic ID cards, digital certificates, e-tickets, and other confidential documents.

The growth of information technology has driven changes in consumer behavior, one of which is through e-commerce platforms such as Shopee. This phenomenon has generated a large number of customer reviews, including those for local cosmetic products such as Wardah. These reviews serve as an important source of information for understanding customer perceptions and satisfaction levels. However, manual analysis of large and linguistically diverse datasets is inefficient and potentially subjective. This study aims to implement the multi-category Naive Bayes algorithm to classify the sentiment of Wardah product reviews on Shopee into three categories: positive, negative, and neutral. The data were collected using a web scraping technique and processed through a series of preprocessing stages including case folding, tokenization, stopword removal, stemming, and text cleaning. Subsequently, term weighting was performed using the TF-IDF method prior to classification. Model performance was evaluated using a confusion matrix as well as accuracy, precision, and recall metrics. The results indicate that the multi-category Naive Bayes algorithm achieved an accuracy of 86.00%, a precision of 86.63%, and a recall of 98.24%. This approach can assist business practitioners in objectively understanding customer opinions and support decision-making in business strategy and product development.

Jakarta, the capital of Indonesia, is known for its high congestion levels. Data from the TomTom Traffic Index shows that Jakarta ranked 30th in the world in 2023 as one of the most congested cities, with a congestion level reaching 53% during peak hours. Pisangan Lama in East Jakarta is one of the densely populated areas, adjacent to busy roads. The main campus of STIKOM CKI, also located in East Jakarta, is situated along a route prone to heavy traffic. Given the congestion issues and the lack of information on the nearest routes, this study aims to implement the A* algorithm to find the shortest route from Pisangan Lama, East Jakarta, to the main campus of STIKOM CKI. The A* algorithm is chosen for its optimal routing capabilities. Based on research on three routes (Jl. I Gusti Ngurah Rai, Jl. Basuki Rachmat, and Jl. Raya Kalimalang), the results show that the route via Jl. Basuki Rachmat is the shortest, with a distance of 7.7 km. The implementation of the A* algorithm is expected to provide an efficient solution for the community in finding the nearest route.

Computers in one of the network companies at PT. Estrada uses the Fortinet operating system. The final result expected through this implementation is to comprehensively see the capabilities of the firewall on Fortinet in overcoming the problem of blocking social media applications and streaming platforms during working hours. Blocking the application in question is the ability to filter web processes such as Facebook, Instagram, YouTube, etc. In the tests carried out, web filtering was able to block applications on social media and streaming platforms, which proves that the performance of web filtering is quite good. In analyzing web filtering performance, use the office hour rule tool by carrying out the rule schedule in the Fortinet network and displaying all the information in detail. The final result obtained in the network application filtering simulation process using Fortinet is that every network sent cannot be entered (blocked) on both social media applications and streaming platforms.

This study aims to describe the implementation of instilling Islamic Religious Education values in the aspects of the Qur’an and Aqidah at TPQ Fattuhul Qulub, Doyo Baru District. The background of this research is based on the importance of Islamic religious education in shaping children’s character and morals from an early age amid the decline in the morality of the younger generation. TPQ, as a non-formal educational institution, has an important role in instilling Islamic values through learning the Qur’an, aqidah, and morals. However, in its implementation, several obstacles are still found, such as the low understanding of students regarding religious values, varying abilities in reading the Qur’an, and the lack of support from family and community environments.This study employed a descriptive qualitative approach. Data were collected through observation, interviews, and documentation at TPQ Fattuhul Qulub, Doyo Baru District. The focus of the research includes the planning, implementation, and evaluation processes of instilling Islamic Religious Education values in the aspects of the Qur’an and Aqidah.The results of the study indicate that the instillation of Islamic Religious Education values has been carried out through structured stages of planning, implementation, and evaluation. The learning process was conducted using the methods of Iqra’, tahsin, tahfidz, talaqqi, lectures, role modeling, habituation, and exemplary stories. In the Qur’anic aspect, students were guided to read the Qur’an according to tajwid rules and memorize short surahs, while in the Aqidah aspect, students were taught the pillars of faith, the attributes of Allah and His Messenger, and the formation of Islamic morals. The evaluation results showed improvements in Qur’anic reading skills, memorization, understanding of aqidah, and changes in students’ religious behavior, such as becoming more disciplined, polite, and diligent in worship. This success was supported by the exemplary behavior of the teachers and the involvement of parents in the learning process.

Market levies are a regional taxation category that holds significant promise for increasing regional fiscal resources, complementing local tax revenues. The objectives of this study are; (1) Understanding the Communication Mechanism in the Implementation of Market Service Fee Policy in Gorontalo City. (2) Examination of Resource Availability in the Implementation of Market Service Tax Policy in Gorontalo. (3) Understanding the Bureaucratic Framework in the Implementation of Market Service Tax Policy in Gorontalo City. (4) Examination of the Implementation of Market Service Tax Policy Disposition in Gorontalo City. The method used in this study is a descriptive qualitative method. The results of this study indicate that the communication of market service fee policy has been carried out through systematic formal channels and is supported by a clear bureaucratic structure and division of tasks, but its implementation is still not optimal. This is caused by several obstacles, including unequal understanding and distribution of information among traders, limited resources in terms of both quantity and quality of human resources, budget, and inadequate market facilities. Furthermore, weak coordination and suboptimal implementation of SOPs in the field also impact work consistency, while the disposition or attitude of implementers who have demonstrated commitment but are not yet unified requires a more comprehensive strategic approach. Therefore, integrated efforts are needed, including improving the communication framework, strengthening human resource capacity, improving facilities, stricter supervision, and ongoing coaching to create more effective and professional policy implementation.

Field Experience Practice (PPL) or internship is a practical course carried out directly in a company according to the student's field of study, with the aim of integrating lecture theory and real work practice.

Digital transformation has positioned artificial intelligence (AI) as a major driver of organizational change and innovation. This study aims to analyze the influence of AI implementation on transformational leadership dynamics and the shifting role of leaders in managing human resources through a Systematic Literature Review of reputable studies published within the last five years. The findings indicate that AI acts as a catalyst in strengthening the dimensions of intellectual stimulation and individualized consideration through predictive analytics and talent personalization. The automation of administrative and repetitive tasks enables leaders to focus more on strategic vision, organizational innovation, decision-making, and emotional engagement with employees. However, the effectiveness of AI implementation is highly dependent on leaders’ digital literacy, adaptive capabilities, and readiness to integrate technology into organizational processes. This study contributes by proposing a hybrid leadership framework that combines artificial intelligence with human emotional intelligence to support more effective leadership practices. The practical implications emphasize the importance of leadership development that prioritizes empathy, ethical awareness, and algorithmic transparency in order to maintain trust, encourage sustainable innovation, and strengthen organizational resilience in increasingly dynamic and volatile environments.

This study aims to analyze public relations strategies in the implementation of the Mental Revolution Program through Instagram at the Coordinating Ministry for Human Development and Cultural Affairs of the Republic of Indonesia. The Mental Revolution represents an effort to transform public mindsets, attitudes, and behaviors based on the values of integrity, work ethic, and mutual cooperation in order to build a progressive and competitive nation. This research employs a descriptive qualitative approach with a case study method. Data were collected through observation, in-depth interviews, documentation, and triangulation to ensure comprehensive findings. The results indicate that the implemented public relations strategies have optimally utilized social media as a means of public communication, particularly in reaching younger audiences. These strategies include the development of positive content, cross-sector collaboration, and the use of media relations to expand information dissemination. The SWOT analysis reveals that the main strengths lie in effective team coordination, structured communication strategies, and a strong organizational culture, while weaknesses include limited human resources and insufficient technological support. Opportunities arise from extensive networks with various institutions and media, whereas threats stem from public perceptions and limited communication competencies. In practice, the Mental Revolution Program is implemented participatively through various initiatives such as Indonesia Serving, Clean, Orderly, Independent, and United, which are disseminated via Instagram. However, its implementation has not been evenly distributed across regions and has only reached approximately 70%, due to budget constraints and varying levels of commitment among local governments. Therefore, the success of this program largely depends on synergy among stakeholders and consistency in internalizing transformative values within society.

Sustainability issues encompassing economic, social and environmental aspects are driving reform in the global financial sector, including in Indonesia. Although the OJK has published a Sustainable Finance Roadmap since 2015, Indonesia does not yet have comprehensive green finance regulations in the banking sector. This study aims to analyse the state of green finance regulation in the Indonesian banking sector and compare it with China’s Green Credit Guidelines, in order to identify relevant aspects for adoption in strengthening national green finance policy. This study employs a normative legal methodology using a legislative and comparative law approach, alongside a qualitative descriptive-analytical analysis of secondary data. The author found that green finance regulations in Indonesia remain fragmented and scattered across various sectoral legal instruments without adequate integration, thereby creating loopholes for greenwashing practices and the adoption of green principles that are merely administrative in nature. The Sustainable Finance Committee mandated by the P2SK Act has not yet been established, exacerbating the lack of coordination between institutions. In contrast, China, through its 2012 Green Credit Guidelines and 2016 Guidelines for Establishing a Green Financial System, demonstrates a regulatory model that is hierarchical, standardised, and legally binding. A comparison of the two identifies four relevant aspects for Indonesia to adopt: an integrated regulatory approach, standardisation of environmental risk operations, strengthening of oversight mechanisms and due diligence, and cross-sectoral institutional coordination. Consequently, Indonesia requires comprehensive, dedicated green finance regulations and must promptly establish the Sustainable Finance Committee as the sole coordinating authority.

Management psychology is an important approach in managing educational organizations, as it emphasizes understanding individual behavior, motivation, and patterns of interaction within an institution. In practice, educational management requires not only managerial skills but also insight into psychological factors that influence teachers’ performance, the learning process, and overall organizational dynamics. Therefore, studying management psychology is relevant to examine how these concepts are applied in educational settings. This study aims to explore the development of research on management psychology in the field of education and to identify its role and contribution to improving the effectiveness of educational organizations. The research questions addressed in this study are: (1) how has management psychology been developed in educational research, and (2) how does it contribute to enhancing the effectiveness of organizational management in education? This research employs a qualitative literature review method. The literature search was conducted using the Google Scholar database with the assistance of the Publish or Perish application, using the keyword “management psychology.” From the initial 30 articles identified, a screening and selection process was carried out, resulting in 5 articles that were analyzed in depth. The findings reveal three main themes in the literature: classroom and learning management, leadership in educational organizations, and the development of work environment and human resource performance. These results indicate that management psychology plays a significant role in improving the effectiveness of educational institutions. Therefore, future research is recommended to examine the empirical application of management psychology across various educational organizational contexts in order to gain a more comprehensive understanding.

The increasing complexity of urban road networks demands intelligent navigation systems capable of determining optimal routes efficiently. This research implements the Dijkstra Shortest Path algorithm to optimize route search on a location navigation system in Medan City. The system models a road network as a weighted graph comprising 57 strategic locations and over 90 road connections, represented using adjacency list data structures. The Dijkstra algorithm, implemented in Python using the heapq module for priority queue management, achieves an optimal time complexity of O((V+E) log V). The system features five main functions: shortest route search, popular routes, location listing, dynamic location addition, and dynamic road connection addition. System testing using a case study from Kualanamu Airport to the University of North Sumatra (USU) yielded an optimal route of 16.5 km through 4 road segments. Results demonstrate that the system successfully determines the most efficient route, provides accurate distance and travel time information for multiple transport modes (motorcycle, car, walking), and presents step-by-step journey guidance. This research contributes as a practical reference for applying shortest path algorithms in urban areas and serves as a foundation for developing more complex navigation applications in the future.

The smart city concept has emerged as a primary solution to address various global urbanization challenges. However, its implementation in developing countries frequently encounters unique obstacles, such as limited infrastructure, constrained budgets, and varying levels of community readiness. This study aims to identify and analyze the critical success factors for smart city implementation in developing nations using a literature review approach. The research employs a Systematic Literature Review (SLR) method, adapting the PRISMA guidelines. Data collection was conducted by screening scientific articles from leading academic databases published over the last five years. The review results indicate that the success of a smart city in developing contexts does not rely solely on technological advancement. There are four primary dimensions acting as determinants: (1) the governance dimension, encompassing regulatory support and bureaucratic transparency; (2) the technological infrastructure dimension, involving equitable internet access and centralized data integration; (3) the human resources dimension, focusing on the digital literacy of citizens and government apparatus; and (4) the financial dimension, which includes innovative financing models and public-private partnerships. The conclusion of this review emphasizes that cross-sector collaboration and strong leadership commitment remain the most crucial foundations. These findings are expected to provide a strategic reference framework for local governments in designing more sustainable and targeted smart city roadmaps.

The Labor-Intensive Housing Program is one of the Surabaya City Government’s policies aimed at reducing poverty and unemployment through labor-intensive community empowerment. This study aims to describe and analyze the implementation of the Labor-Intensive Housing Program (RPK) at the Pitstop business unit in Lidah Kulon Village, Lakarsantri Subdistrict, Surabaya City. This study employs a qualitative method with a descriptive approach, utilizing Van Meter and Van’s policy implementation theory. Primary data were collected through interviews and observations, while secondary data were derived from official documents and relevant publications. The results showed that the implementation of the Pitstop Labor Intensive Housing Program has not yet been optimal. In terms of policy standards and objectives, the program’s goals have been clearly defined but have not yet been fully achieved. Regarding resources, the availability of facilities and funding is adequate, but there are still limitations in human resources, particularly skilled technicians in the automotive repair field. Inter organizational communication has taken place but has not been intensive enough to support business sustainability. Characteristics of the implementing agents indicate that the structure of the Labor-Intensive Housing team has been clearly defined; however, implementation in the field has not been optimal due to weak coordination and communication. Economic, social, and political conditions-such as a less-than-strategic business location and high competition from similar businesses-have also contributed to the low number of customers. Meanwhile, the disposition of the implementers demonstrates a positive attitude in supporting the Labor-Intensive Housing program. The Labor-Intensive Housing Program must be supported by professional mechanics through education, certification, and collaboration with the private sector and training institutions to ensure the quality of services. In addition, building public trust, coordination among stakeholders, and intensive support through monitoring and evaluation are key to the success and sustainability of the Labor-Intensive Housing Program.

In conclusion, the Director of Photography has effectively fulfilled their role in producing visual quality that supports message delivery in the documentary Bisakah Aku Kembali? about Javan slow loris rehabilitation.

Congestive heart failure (CHF) is a cardiovascular disease that frequently causes shortness of breath (dyspnea) and negatively impacts patients’ quality of life. The management of dyspnea involves not only pharmacological approaches but also nonpharmacological interventions, one of which is handheld fan therapy, which works by stimulating sensory receptors in the facial area. This study aims to describe the effect of handheld fan therapy on reducing shortness of breath in patients with CHF. This study employed a descriptive design using a case report method on a single 63-year-old female patient diagnosed with CHF. The intervention was conducted over four days, involving the use of a handheld fan for 10 minutes, held at a distance of 15–30 cm from the face and directed toward the nose and mouth. Measurements were taken before and after the intervention using respiratory rate and oxygen saturation as parameters. The results showed a gradual decrease in respiratory rate from 24 breaths/minute to 18 breaths/minute, as well as an increase in oxygen saturation from 91% to 96% during the intervention period. These findings indicate an improvement in breathing patterns and increased respiratory efficiency in the patient. Handheld fan therapy is effective as a nonpharmacological intervention for reducing shortness of breath and improving oxygenation in patients with CHF. This intervention is safe, easy to use, and can be implemented as a complementary therapy in nursing practice.
