Abstract

In the era of the industrial revolution 4.0, we need remote technology and products that d not created new medical waste piles. An unhealthy lifestyle can cause many diseases, either degenerative diseases, namely over rate cholesterol and blood sugar level. High cholesterol and blood sugar levels are causes of major influence on atherosclerosis, stroke, micro-vascular, and cardiovascular complications. We offer a non-invasive cholesterol and blood sugar monitoring device based on red LED and infrared light absorption using the Nellcor DS-100A sensor. This technology can help reduce cumulative medical waste and help health workers to monitor patients remotely. This study used ten random samples to calibrate cholesterol and blood sugar levels. The coefficient of determination values were 0.9580 and 0.9581, respectively, which gave excellent values so that the study is continued by collecting data. Data retrieval use 20 random sample data to measure cholesterol and blood sugar levels, the average accuracy prototype is 90.26% and 91.16%, respectively. It shows great potential in determining estimation value at cholesterol and blood sugar levels. The monitoring system can show the data on the LCD display in Blynk Application with the average time required of 1.07 s.

Abstract

Concentration in learning has a big impact on determining learning outcomes. Some of the conditions experienced by students who find it difficult to maintain concentration during the learning process are caused by many factors. Among them is the atmosphere of a noisy learning environment. One way to determine the learning concentration condition is by measuring beta brain waves using Electroencephalography (EEG). This study aims to analyze the effect of the murottal stimulus of Al Baqarah verses 1-10 on beta brain wave activity and its relationship with learning concentration. The research method used is experimental. Subjects in this study were 6 students of UIN Walisongo Semarang, with inclusion criteria ranging from 20-23 years old, Muslim, not hearing impaired, physically and mentally healthy, and not using drugs. The stages of research consisted of 4 stages; first, the research subjects carried out the pre-test without stimulus; second subject measured their brain waves without stimulus; third, subjects measured brain waves with stimulus; and finally, the research subjects carried out the pre-test with stimulus. The analysis results using the T-test, which stated that the average comparison of beta brain waves in the two groups before and after being given the murottal Al-Qur’an stimulus showed a p-value of 0.0003 (p<0.05). While the results of the pre-test and post-test T-test showed a p-value of 0.017 (p<0.05). It shows that the murottal stimulus of Al Baqarah verses 1-10 effects changes in beta waves and the level of learning concentration.
