The digitalization era is developing rapidly in Indonesia. The pandemic that occurred accelerated digital transformation in various fields. Various digital platforms were developed to support the continuity of education during the pandemic so that they could develop digital skills and improve the status of digital literacy in Indonesia. In addition to the positive impacts, there are also negative impacts from the development of digital transformation. The National Cyber and Crypto Polytechnic which focuses on information security is committed to encouraging increased digital skills and literacy in the surrounding community. Therefore, this time the National Cyber and Crypto Polytechnic located in Bogor Regency began to focus on developing digital skills and literacy among high school students or equivalent in Bogor Regency. The students' digital literacy status was first measured and then the right program or activity was determined to develop their digital skills and literacy. The digital literacy status was measured based on four pillars, Pillar 1 Digital Skill, Pillar 2 Digital Ethics, Pillar 3 Digital Safety, and Pillar 4 Digital Culture. Data collection was carried out by giving questionnaires to 276 high school students or equivalent who used the internet in Bogor Regency. Students give a score to each statement and then the score will be calculated as an average per pillar. The digital literacy index is obtained from the average score of all pillars. The digital literacy index result is 3.14 which is higher than the West Java digital literacy index of 2.78. In addition, pillar 2 Digital Ethic has the lowest score among the four pillars so that the next program is expected to aim to increase this score.

This research aims to analyze the comparison of using contextual learning media (concrete) involving technology in improving the mathematics learning outcomes of first-grade elementary school students.  The research method used is a qualitative method with a descriptive approach.  Data collection was conducted through observation, interviews, and documentation to understand students' interactions with creative learning media and its impact on their understanding of basic mathematical concepts.  The results of this study indicate that the use of learning media, both contextual (concrete) and involving technology, such as visual aids and educational games, can increase students' interest in learning, help them understand the material more easily, and have a positive impact on their mathematics learning outcomes.  It is hoped that the use of innovative and creative learning media can continue to be applied in mathematics education to support the cognitive development and interest of students in mathematics from an early age.  However, the use of concrete learning media involving counting boards and jumping frogs is hindered by time efficiency.
