This article examines the impact of the common law legal system on the development of law in Indonesia, focusing on how elements of the system have influenced national legal practice and theory. This study uses a qualitative approach through document analysis and literature studies related to the history of Indonesian law and legal practice in common law countries. The results of the study indicate that although Indonesia adheres to a civil law legal system, the influence of common law is visible in certain aspects, such as the principle of precedent, legal interpretation, and the application of customary law. In addition, this study also explores how the integration of common law elements can enrich the dynamics of Indonesian law, especially in the context of legal reform and the achievement of substantive justice. With a better understanding of this influence, it is hoped that recommendations can be produced for the development of a legal system that is more responsive and adaptive to the needs of society.

The theory of legal positivism plays a crucial role in the development of modern legal thought by emphasizing the importance of written and systematic norms in law enforcement. This approach is based on the assumption that the law is the product of regulations made by state institutions, as stipulated in various laws, including the 1945 Constitution, the Criminal Code (KUHP), and Law Number 12 of 2011 concerning the Establishment of Laws and Regulations. The methodology used in this study is qualitative analysis through literature studies and interviews with legal experts to explore the understanding of the application of positivism theory in legal practice in Indonesia. The results show that although positivism provides a strong framework for legal analysis and supports legal certainty, there are still significant challenges related to the application of the values of justice and morality in the legal system. This study concludes that to achieve social justice, there needs to be an integration between positivism and moral principles in modern legal practice.

The most common ankle injuries are ankle sprains. Ankle sprain is an overstretch of the lateral ligament complex due to inversion and plantar flexion forces which occur suddenly when the foot does not rest perfectly on the floor/ground, which generally occurs on an uneven floor/ground surface. An ankle sprain injury is usually caused when the surface of the ground or field is uneven so that the foot enters the uneven part of the ground and the foot position is not good and shock allows the support on the foot to be unbalanced. Therefore, physiotherapists play an important role in the community in promotive and preventive steps to overcome the problem of ankle sprains. Steps that can be taken are to provide education to the public about ankle sprains which includes understanding, signs and symptoms, prevention methods, main treatment, further treatment, and demonstration by respondents. The initial method for finding out the situation that occurs in the field is observation by interviewing teachers and related extracurricular students. The results of educational activities regarding ankle sprains are very useful for each individual's life. Knowledge about ankle sprains also increased from 5 to 24, this means students are starting to understand.
