Abstract

Health monitoring is important in the technology and information era. A health monitoring device must possess high accuracy in monitoring an individual's health. The MAX30100 sensor still exhibits low accuracy and requires improvements to enhance its precision. This study proposes a remote health monitoring system based on a MAX30100 sensor for heart rate and oxygen saturation detection. The digital signal processing method uses the Chebyshev II filter on PPG to reduce noise, and the RSA algorithm is employed to enhance data security. The results of testing the MAX30100 sensor value without a filter produced the lowest error value of 0.97%, the highest 6.59% for BPM, the lowest error value of 1.88%, and the highest error of 2.66% for SpO2. The MAX30100 sensor with the Chebyshev II filter that the author proposed has the highest level of accuracy with a low error value compared to previous tests, with the lowest error value of 0.23% and the highest 0.99% for BPM and the lowest error value of 0% and the highest error of 0.2% for SpO2. The RSA algorithm ensures secure data transmission from data modification by eavesdroppers. The average total time required by the system is 542.9 ms.

Abstract

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.
