Thanks to rapid technological advances, it is increasingly easier to provide services to the public. One example is the electronic land certificate service. The time and costs of registering land certificates can be reduced by using the latest technological methods. The research method used by the author is a statutory approach and normative research methods. The research results show that significant technological progress can be made by digitizing the current paper-based land registration system. One of them is the issuance of electronic certificates as regulated in Regulation of the Minister of ATR/Head of BPN No. 1 of 2021 because the Electronic Transaction Information Law and the Job Creation Law only regulate electronic certificates, this electronic certificate is legal and the risk of causing problems is very small. Technology supporting the use of electronic land title certificates is developing rapidly and is now very useful. As an institution that provides electronic services in the land sector, BPN not only improves data quality control, but also continues to improve electronic services with professional staff. The implementation of land title certificates still has shortcomings in terms of infrastructure, equipment, human resources and electronic data quality.

Immigration is related to the traffic of people entering or leaving Indonesian territory and its supervision to maintain state sovereignty. Immigration functions include providing immigration services, law enforcement, and maintaining the security and comfort of the country, while contributing to the development of community welfare. With the increase in crimes involving fake identities or misuse of other people's identities, immigration must be stricter in checking travel documents used by Indonesian citizens and foreign nationals when entering and leaving Indonesian territory. Therefore, immigration introduced a new passport design and implemented the use of electronic passports. The research method used in this research is a descriptive qualitative method. The research results show that changes in passport design can increase state sovereignty and security, because the new design is difficult to imitate. This can be seen from the materials used in making the new passports as well as the designs that highlight elements of Indonesian culture. Applying for an electronic passport does require higher costs than a regular passport, but offers advantages that conventional passports do not have, including a better level of security. Using an electronic passport also makes it easier for the holder to undergo immigration service administration because this passport uses a biometric system that only needs to be scanned.

Fractal structures play a crucial role in improving material properties due to their unique self-similar geometries. These geometrical patterns exhibit repetition at multiple scales, which can enhance surface area, strength, and other mechanical characteristics. This study investigates the influence of fractal patterns on the crystal growth and mechanical performance of metallic materials, focusing on strength, toughness, and hardness. Using a combination of computer simulations and laboratory experiments, the research models metal crystal formation under controlled conditions, where fractal characteristics are introduced through diffusion-limited aggregation (DLA) and electrodeposition methods. The findings reveal that embedding fractal patterns into the crystal growth process can increase material strength by approximately 20% compared to conventionally structured metals. This improvement is attributed to the efficient stress distribution within the fractal geometry, which minimizes stress concentration points and enhances resistance to fracture. Additionally, materials with fractal-based microstructures exhibit better toughness and deformation resistance, improving durability under mechanical load. The study also examines the underlying mechanisms of these effects, emphasizing the role of fractal-induced microstructural control in optimizing material integrity. These results demonstrate the significant potential of fractal-based material design in engineering stronger, lighter, and more flexible metallic components. The research contributes to the broader understanding of how geometric complexity can be harnessed to develop advanced materials for applications in construction, automotive manufacturing, and flexible electronics, thereby supporting the development of next-generation high-performance materials.
