Crimes of terrorism are not only done through the internet, but can also be done through networks that can send signals such as telephone communications. By implementing a cyber terrorism policy at the police, terrorism cases will decrease every year. The implementation of this policy helps to overcome the problem of terrorism in Indonesia.

The research aims to determine the implementation of policies regarding cybercrime applications at the Metro Jaya Police, Central Jakarta in accordance with the Electronic Transactions of Electronic Information and / or Electronic Documents regulations. The basic theory used in this research is Edward III (1980), which states that policy implementation is influenced by communication, resources, disposition, and bureaucratic structures. This study used a qualitative descriptive method by interviewing several informants. The results showed that the Central Jakarta Metro Jaya Police had implemented a cybercrime prevention policy through communication, resources, disposition, and bureaucratic structures to overcome cybercrime. Barriers to policy implementation are limited personnel such as IT and cyber forensics experts, budget and facilities and infrastructure to support the disclosure of cybercrime cases. Training is needed for cyber police in using technology, both by the police and universities. This step is necessary to recruit information technology experts. The urgency of the need for experts must also be balanced with the presence of sophisticated facilities and infrastructure to support network security and also to facilitate tracking criminals so that cybercrime cases can be resolved quickly.

Parents need to notice attention to the nutritional status of toddlers to prevent nutritional disorders. Therefore, we need a system that can make it easier for parents to access information about the nutritional status of toddlers. The system that can be used is a technology system. The author conducted a literature analysis with a simplified approach in 10 technology journals for assessing the nutritional status of children under five for the 2012-2022 period. Based on this research, the authors conclude that technology to assess nutritional status in toddlers is very effective because it makes it easier for health workers to assess and record nutritional status, it makes it easier for parents to know the nutritional status of their toddlers, but in this study several things that still need to be considered include: understanding the use of technology for parents, the readiness of tools such as smartphones or other software that can be used to access technology to assess the nutritional status of toddlers.
