A sports center is a place that accommodates various types of sports activities that can increase a person's physical, mental and social potential in certain fields in a region. The aim of this research is to design a suitable sports center by creating a friendly and inclusive environment for all users and minimizing accessibility barriers. Designing a sports center can be a forum for all users by paying attention to several factors and supporting architectural elements by applying Universal Design principles. The research method used is a qualitative method through ideas by collecting data which includes literature studies and case studies of typologies or similar themes, then followed by analysis as a design guide. The results of the study of the application of the universal design concept to the design of sports centers by applying the principles of universal design, namely the existence of special paths for disabled users, ramps that will be used as a means of vertical connection between floors, providing accessible places for wheelchair users, making signs and clear information so that visitors can access it more easily, creating open circulation that is safe and comfortable for visitors.

The implementation of environmental law influenced the success of the Eco Town program in maintaining the sustainability of river ecosystems by providing a strong foundation for preserving the environment. The implementation of strict regulations related to environmental protection and river management is key in ensuring that development within Eco Town does not damage the river ecosystem. In several case studies such as the Ciliwung River and the Brantas River, the implementation of environmental law has recorded significant improvements in the sustainability of river ecosystems. The main challenges faced in implementing environmental laws to support Eco Town programs are resource limitations, especially in terms of funds, technology, and natural resources. These limitations may hinder the effectiveness of the program and affect the ability to address environmental problems such as industrial or domestic waste management, and maintain ecological balance. To overcome these challenges, concrete measures such as improved accessibility and technology transfer, sustainable management of natural resources, and investment in environmental infrastructure are needed. By ensuring a solid environmental law implementation and paying attention to these limitations, the Eco Town program can run more effectively and efficiently in maintaining the sustainability of the river ecosystem and realizing a vision of sustainable development.

Methodology is a very important basic framework in the design and development of professional software, aimed at creating an information system that meets the business needs of an organization. Success in software development relies heavily on managing the software project as a whole. Establishing a methodology includes high dynamics in the design stages of a model that describes the activities and life cycle of a system. SDLC (Systems Development Life Cycle) or Systems Development Life Cycle, in the context of systems and software engineering, is a process that includes the creation and modification of systems, as well as the models and methodologies used to develop them. This discussion will explain the analysis of selecting software development methodologies, including waterfall, prototype, iterative, spiral, and rapid application development (RAD). It is hoped that the results of this discussion can provide considerations in choosing and using the right methodology based on each individual's needs, strengths and weaknesses, as well as other factors such as familiarity with technology, system complexity, system reliability, and short and precise time requirements, as well as referencing several scientific journals.

The Age limit requirements on job vacancies are currently being criticized by the public through social media. Age restrictions are a form of age discrimination. Companies/employers often set an age limit for workers ranging from 18-25 years old. This age requirement is considered to make it difficult for prospective workers to find work, especially for contract workers and women. This study describes the limitation of working age as a form of discrimination and the policies governing age requirements in Indonesia. The research method used in this research is normative legal research using a statute approach, comparative approach, and conceptual approach. The results of this study show that in Indonesia there are no regulations or policies that regulate and provide legal protection regarding age discrimination of workers and it is important for the government and companies to consider more inclusive policies related to age restrictions in recruitment. In addition, there needs to be an effort to provide training and employment opportunities for workers who are above the age limit so that they can still be productive.
