The characteristics of prospective new students who re-register can produce a distribution pattern of new student admissions according to the data obtained. The results of the distribution pattern can be used as material for decision making in determining the socialization and promotion of study programs at universities. To produce a pattern, it requires grouping based on data that has the same character. The k-means algorithm, which is an algorithm in data mining processing methods for clustering, is successful in classifying new student admissions by maximizing the similarity of characteristics between data in one cluster which is different from data in other clusters. This is evidenced by direct application based on data mining procedures to data on new student admissions for Engineering Faculty, Manado State University for 2018, 2019, and 2020 with 8 selected variables. After clustering using the RStudio application, Data 2018 generates 6 clusters, 2019 data generates 3 clusters, and 2020 data generates 4 clusters. There are some re-registration characteristics that are common to all three years, which can be read easily after clustering.

The prevalence of Ear, Nose, and Throat (ENT) diseases presents diagnostic challenges, especially in resource-limited settings. At THB Bekasi Hospital, constrained specialist availability and long consultation queues highlight the need for an accessible diagnostic solution. This study aims to develop an expert system for diagnosing ENT diseases using the Extreme Programming (XP) methodology, incorporating the forward chaining technique for inference. The research includes assessment, knowledge acquisition through expert consultations, system design, and rigorous testing. The system was developed as a mobile application using Android Studio, enabling users to input symptoms and receive real-time diagnostic insights. The knowledge base integrates data from medical experts, synthesizing 11 diseases and 35 symptoms into a robust decision-making framework. The diagnostic process applies predefined rules to ensure accuracy in identifying conditions such as sinusitis, laryngitis, and otitis. Evaluation results demonstrate a 100% match accuracy during testing with 15 test cases, confirming the system’s reliability. The application offers users rapid diagnostic assistance, promoting timely treatment for ENT issues, although it does not substitute medical professionals. By leveraging ubiquitous smartphone access, this system addresses gaps in healthcare accessibility and enhances patient autonomy. This research contributes a scalable framework for deploying expert systems in other medical domains. Future improvements include integrating geolocation services for nearby specialist referrals and adopting backward chaining for more complex diagnoses, thereby broadening its applicability and utility

Community welfare is a primary objective of national development, encompassing various aspects such as health, education, and decent employment, all of which play crucial roles in achieving national stability and progress. However, welfare is not solely dependent on economic factors but also on the overall quality of life. Unfortunately, disparities in welfare persist across different regions, influenced by local environmental factors, including access to education, which in turn affects job opportunities and income levels. Inequalities in employment opportunities can potentially slow down national development by reducing the number of individuals capable of contributing productively to key economic sectors. To enhance national development, further analysis of welfare indicators such as the open unemployment rate, human development index, labor force participation rate, and poverty levels is essential. Therefore, this study conducts cluster analysis on welfare indicators across districts/cities in Central Java for the year 2023. Both hierarchical and non-hierarchical (K-Means) clustering methods are employed to identify patterns of inequality by partitioning data into groups based on specific similarities. This approach facilitates a more effective review of policies to address welfare disparities across various regions. The findings indicate that the welfare indicators in Central Java are in a relatively poor condition, with low labor force participation rates, low human development indices, and high poverty rates. The hierarchical and non-hierarchical cluster analysis identified 5 optimal clusters, with all welfare variables having significant influence, requiring four iterations to reach the final centroids.

In an effort to support investment growth, the Omnibus Law simplifies the licensing process and provides fiscal incentives. However, criticism emerged mainly from environmental groups who expressed concern over the potential reduction in environmental protection as a consequence of these changes. When the Omnibus Law on Job Creation was passed, mass protests and demonstrations emerged in various cities in Indonesia. Labor unions and activist groups opposed the changes in the law, demanding the maintenance of workers' rights and environmental sustainability. This discontent reflects the divisions among the public regarding the impact of the Omnibus Law on daily life and the future of the country. The government needs to communicate with various stakeholders, including labor unions, employers, and environmental groups, to strike a fair balance and ensure that policies reflect the common interest. The purpose of this paper is to find out the differences between the Manpower Law and the Job Creation Law. The author will use normative legal research conducted by examining secondary data in the form of primary, secondary and tertiary materials. This research is also called library research or document study, because it is mostly done on secondary data in the library. The conclusion of this paper is that the labor cluster of the Job Creation Law (omnibuslaw) is a legal product that relieves employers and is binding on workers. That the comparison of the Manpower Law with the Job Creation Law is a legal product that is made into one big economic and investment issue, in this case the Job Creation Law's labor cluster actually ignores the philosophy of the Manpower Law it replaces.

This study focuses on strengthening brand equity in the Visual Communication Design (VCD) study program at higher education institutions by implementing interactive multimedia. The background of the problem lies in the importance of branding innovation in addressing the increasing competition in the education sector. The purpose of this research is to evaluate the impact of interactive multimedia on four dimensions of brand equity: brand awareness, brand loyalty, perceived quality, and brand associations. The methodology employed involves a mixed quantitative and qualitative approach. Data was collected through a survey of 100 respondents using a Likert-scale-based questionnaire and in-depth interviews with relevant participants. A paired t-test was used to analyze changes in brand equity perceptions before and after implementing interactive multimedia. The results show a statistically significant increase in brand awareness by 20% (p < 0.01), brand loyalty by 25% (p < 0.01), perceived quality by 18% (p < 0.01), and brand associations by 19% (p < 0.01). These findings provide practical contributions to higher education institutions by demonstrating that interactive multimedia is not merely a communication tool but an effective strategy for building emotional engagement with audiences and enhancing institutional reputation. Furthermore, qualitative insights highlight the role of interactive multimedia in fostering deeper emotional connections and improving perceptions of quality. This research supports adopting technologies like Augmented Reality (AR) and Virtual Reality (VR) to enrich future learning experiences. Continuous implementation and innovation in interactive content are also necessary to remain relevant and competitive in the dynamic education market.

Business legality is the identity of a business that legalizes a business so that it is recognized by the community. Business legality must be valid according to applicable laws and regulations so that the business can be protected by various documents that are valid in the eyes of the law. One of the supporting factors for the sustainability of a business is influenced by the existence of legal elements of the business being run. Business permits that must be owned by the community are a business establishment deed, business entity NPWP, trade business license (SIUP), company domicile certificate (SKDP) and business registration number (NIB). The increase in community businesses in Sei Bingai District, Langkat Regency has triggered many business permits that are not directly supervised by the local government. Community business permits are important documents in supervising the running of these community businesses. The types of businesses in Sei Bingai District also vary, such as tourism, C mining, trade, factories and so on.
