Abstract

Traffic accident, particularly two-wheeled vehicles, is a problem for the Government, especially the Resort Police Traffic Unit (Satlantas Polres). The factor that causes the traffic accident incident is divided into three types, namely human factor, vehicle factor, and road or environment factor. The human factor is the most common factor for an accident. Fatigue factor that causes someone to feel sleepy while driving often results in a traffic accident. Based on the problem, the researcher wanted to create a technology innovation of a motorized driving safety system in the form of a helmet. The researcher made an innovation of a helmet that can detect drowsiness through the driver's eye blink duration. The drowsiness will be detected by using a camera sensor. The camera sensor used was Open MV camera. The method used in detecting sleepy drivers was the eye detection analysis method. The method enable detection based on the data of the duration of eye condition when it is closed and open. The closed eye has a low RBG mean value of 110-113 and an RBG median value of 99-109. Whereas opened eye has a higher RGB mean value of 179-206 and RGB median value of 178-206. The result of the research showed that someone's sleepy condition occurred when closing their eyes for more than 0.4 seconds to 4 seconds. The helmet is also equipped with GPS to monitor the position in the event of an accident as an emergency response effort.

Abstract

Based on data from the Ministry of Health and the Central Bureau of Statistics, it is known that the number of people with disabilities, especially the visually impaired, is 1-1.5% of the total 237 million Indonesian population, which is around 3.75 million blind people. A tool often used to accommodate them is a cane used to feel the ground if there are downgrade and obstructions in front of them. In this study, researchers developed the previous research on blind cane using a 2 axis servo. It was classified using the Fuzzy Logic programming method, which was processed using the Arduino Nano 328P microcontroller. The results of the test on respondents with visual impairments were that they feel accommodating with the tool because the cane users can easily find obstructions with the Navigation Instruction so that they can easily avoid Static obstructions (Static Objects).

Abstract

More and more research results report that exposure to Extremely Low Frequency (ELF) magnetic fields at low intensity can increase cell proliferation. The ELF magnetic field interacts directly with cell membranes, capable of increasing intracellular calcium and under certain conditions affecting cell proliferation. This study wanted to prove the potential of ELF magnetic field radiation with intensity of 200 µT and 300 µT on edamame productivity. The research design used a completely randomized design. The research sample was 250 edamame soybeans of the Ryokkoh-75 variety which were divided into 5 groups. Samples were soaked in warm water for 3 hours and then cured for about 12 hours and exposed to ELF magnetic fields of intensity of 200 µT and 300 µT with variations in exposure time of 60 minutes and 120 minutes. Then it is seeded and planted in the field. Observation of the number of edamame pods and the number of pods was carried out when they were already fruiting, namely day 29 to day 43. The results of the study proved that the number of pods and the number of edamame pods in the group exposed to the 200 µT and 300 µT ELF magnetic fields was higher than the control. It appears that the highest number of fruits and pods occurred in the sample group exposed to the ELF magnetic field intensity of 300 µT. The conclusion is that exposure to the ELF magnetic field intensity of 300 µT has the potential to increase edamame productivity

Abstract

Introduction: Until now, the impact of Extremely Low Frequency electromagnetic field radiation (ELF-EMF) by extra high voltage transmission lines (500 kV-EHVTL) is still debated. While WHO recommends a threshold of magnetic field exposure of 100 µT for up to 24 hours/day is declared safe for health. This study aims to examine the Integration of Extremely Low Frequency Magnetic Field Studies in Science Education: "Case Study on 500 kV-EHVTL". This study is important to support literacy in Environmental Physics and Environmental Radiation courses. The location of the study is a 500 kV EHVTL building located in Gondang Wetan District, Pasuruan Regency, East Java, Indonesia. Measurement of ELF magnetic field intensity using the EMF Tester-827 tool. The measurement position is at point 0 (directly below), and lateral distances of 50m, 100m, 150m, 200m, and 250m from the EHVTL power grid cable, as well as distances of 0m, 1m, 5m, 10m, and 15m from the EHVTL power grid tower. The intensity of ELF magnetic field exposure just below the EHVTL reached a value of 5.73 µT-10,085 µT (increased 170-234 times) compared to the natural magnetic field. While several research results prove that exposure to magnetic fields with an intensity of around 10 µT in vitro causes an increase in cell proliferation. Increased cell proliferation in the human body can have negative effects on health. Based on the research results it was concluded that an increase in the intensity of ELF magnetic field exposure up to 170-234 times can cause biological effects at the cellular level and has the potential to cause health impacts on humans. it is advisable to avoid living under the EHVTL network, and the WHO recommendation that the threshold exposure value of 100 µT is declared safe for humans exposed for up to 24 hours/day needs to be reviewed
