The principle of due process of law is a fundamental pillar in every modern legal system, including in the context of procedural law for judicial review of laws at the Constitutional Court of the Republic of Indonesia. This principle demands a fair, open, and balanced procedure for all parties to the case. However, in practice, the application of this principle often faces various problems, such as limited access to trial information, limited opportunities to submit evidence, and allegations of impartiality by the constitutional panel of judges. This study aims to critically examine the problems of applying the principle of due process of law in procedural law for judicial review of laws at the Constitutional Court. The research method used is normative juridical with a statutory approach and case studies of several Constitutional Court decisions. The results of the study indicate that there is a discrepancy between the normative provisions governing the principle of a fair trial and the factual implementation in court. This condition has the potential to weaken the legitimacy of the Constitutional Court as the guardian of the constitution and the protection of citizens' constitutional rights. Therefore, efforts are needed to reform procedural law at the Constitutional Court to strengthen the application of the principle of due process of law consistently, transparently, and accountably.

The Constitutional Court of Indonesia is a judicial institution with the authority to review laws against the 1945 Constitution of the Republic of Indonesia, resolve disputes between state institutions, decide on the dissolution of political parties, and adjudicate election result disputes. In exercising its authority, the Constitutional Court functions not only as the guardian of the constitution but also as a protector of human rights. This article aims to analyze how the procedural law of the Constitutional Court, as regulated under Law Number 24 of 2003 and its amendments, serves as a crucial instrument to ensure fair, transparent, and accountable proceedings in cases involving constitutional rights. This study adopts a normative juridical approach by examining legislation, legal doctrines, and Constitutional Court decisions that have had a significant impact on the protection of human rights. The analysis reveals that several rulings of the Court have expanded interpretations of human rights, although challenges remain regarding the consistency of procedural application and the effectiveness of decision enforcement. Therefore, strengthening the procedural law of the Constitutional Court is essential for ensuring the substantive and sustainable protection of human rights in Indonesia.
 

Oceanarium s are popular tourist destinations in Indonesia.  This article discusses digital transformation in designing the latest Oceanarium. The research method involves surveys and observations to 2 major Oceanarium locations in Jakarta, one Oceanarium in Singapore and one in Bangkok's Siam Paragon, to get an overview of operations, and the implementation of digital technology. In addition, this research also integrates the author's experience as a public aquarium designer and for 20 years as a manager in one of the public aquariums in the Jakarta area. The current approach needs to involve the integration of IoT technology for aquatic environment monitoring, smart energy management system. The results show that the implementation of interactive technology in several places can create an interesting and memorable learning experience for visitors. One of the technologies that is interesting and preferred by visitors is the use of hologram technology, visitors can feel the sensation of being in the sea and interact with marine animals in a realistic virtual environment. This enhances their understanding of marine flora and fauna and the importance of preserving the marine environment. This digital transformation not only improves the operational efficiency of the Oceanarium, but also enriches the visitor experience through the application of interactive technology. By implementing this strategy, Oceanarium s in Indonesia are expected to continue to grow, make a positive contribution to the preservation of the marine environment, increase public knowledge of marine biology, and provide a high-quality experience for visitors.
