Turunan parsial is one of the fundamental concepts in multivariate calculus that has many applications, such as optimization, data analysis, and mathematical modeling. Understanding theory is often difficult, especially when there is no visual aid. This article discusses the use of MATLAB as a powerful tool for parsial analysis and visualization. Through the use of 3D charting and symbolic computing features, MATLAB facilitates multivariate function analysis. Research on the function f(x,y)=x^2+y^2+xy shows how parsial turunan is observed and visualized in an interactive manner. This article's goal is to encourage the use of MATLAB in long-term math education and research.

The education systems in China and Indonesia have significant differences, although both aim to create an educated generation. In China, education focuses on the development of technical and academic skills with a highly structured and competitive system, especially through the Gaokao exam that determines students’ academic futures. Meanwhile, Indonesia places more emphasis on cultural diversity and character development, with a more inclusive learning approach based on social values. These differences are clearly reflected in the educational structure, curriculum, teaching methods, and assessment systems, which align with the social and economic needs of each country.

Every organization must have problems, problems that often arise in organizations are disharmonious relationships between leaders and their members, or between fellow members. This problem is caused by interference barriers in organizational communication. All organizational activities will run in accordance with their respective duties and functions if communication takes place effectively in all lines of the organization. Conversely, failure to foster effective and harmonious communication will hamper the implementation of tasks in the organization. Without communication there is no coordination, and without coordination there will be overlapping work, confusion of information, and misunderstanding in interpreting and carrying out organizational tasks. Organizational leaders are the spearhead of the organization to create comfort, bring motivation, and foster loyalty to the organization. every organization must apply the principles of public relations and human relations in order to build effective communication quality.

Granting Justice Collaborator (JC) status to perpetrators of criminal acts of corruption is one of the law enforcement strategies aimed at uncovering a wider network of corruption crimes. However, its implementation raises various problems, both in terms of law, morals and justice. This research aims to analyze the regulations underlying the granting of JC status, the criteria for its application, and the challenges that arise in practice. This study uses a juridical-normative method with an analytical approach to statutory regulations, court decisions and legal literature. The research results show that the granting of JC status is often not transparent, giving rise to controversy regarding the integrity of its implementation.
