    Water, in any way it comes, is important for the life of all living things. Indonesia is an area of tropical equatorial with a variation of rain, which is quite high. The regularity of the distribution of rainfall is one of the aspects most important to the activity of the community. As the development of technology, the intensity of rainfall can be measured manually using Ombrometer Observatory tool. The manual tool for measuring the rain precipitation, Ombrometer Observatorium, is used to take data manually. Samples should be taken at 7.00 a.m. everyday using a measuring cup to know the height of the water contained. However, the type is prone to error at the high rainfall intensity, since the drainage of the samples is conducted every 24 hours. Therefore, much water is wasted. To solve the problem, a modification of a rainfall gauge was made, that is Ombrometer Observatory with ultrasonic sensor HC-SR04. The height of the water in the container is sent through a server of which the data is stored in the database every ten minutes to reduce the risk of evaporation. It also minimizes the error in measuring the rainfall intensity. The results have been compared to the ones by BMKG (Meteorology, Climatology, and Geophysics Agency). The correlation value of the measurement ratio reached 0.9739 or 97.39%.

    Recognizing Human Emotion patterns by applying Fast Fourier Transform based on Brainwave Features
    (Ieee, 2019) Yudhana, Anton; Mukhopadhyay, Subhas; Karas, Ismail Rakip; Azhari, Ahmad; Mardhia, Murein Miksa; Akbar, Son Ali; Muslim, Akbar
    The natural ability of humans to receive messages from the surrounding environment can be obtained through the senses. The senses will respond to stimuli received in various conditions including emotional conditions. Psychologically, recognizing human emotions directly can be assessed from several criteria, such as facial expressions, sounds, or body movements. This research aims to analyze human emotions from the biomedical side through brainwave signals using EEG sensors. The EEG signal obtained will be extracted using Fast Fourier Transform and first-order statistical features. Monitoring of EEG Signals is obtained by grouping based on four emotional conditions (normal, focus, sadness and shock emotions). The results of this research are expected to help improve users in knowing their mental state accurately. The development of this kind of emotional analysis has the potential to create wide applications in the future environment. Research results have shown and compared frequency stimuli from normal emotions, sadness, focus and shock in a variety of situations.

    Wireless Communication System For Monitoring Heart Rate In The Detection And Intervention Of Emotional Regulation
    (Ieee, 2019) Al Irfan, Syahid; Yudhana, Anton; Mukhopadhyay, Subhas Chandra; Karas, Ismail Rakip; Wati, Dewi Eko; Puspitasari, Intan
    Based on data from the Indonesian Child Protection Commission (KPAI) cases of violence against children from 2010 to 2015 continued to increase which from 2010 only 171 cases increased to 2015 as many as 6006 which means that every year cases of violence against children continue to increase at least 1000 cases each year. Changes in heart rate in humans can be known through the flow of blood that flows in blood vessels. When the heart beats, the flow in the blood vessels will move so that's when the heart rate can be measured. In this study, a wireless heart rate condition data collection system will be developed and a heart rate condition sensing device that has the same capabilities as devices used in general medical activities. From the results of testing, the system designed the process of sending data goes well where of the 20 devices that send data all of that can be sent properly with a time interval of 1 second but for the sensor reading process some problem need to be solved such as interruptions in the data collection process when participants doing activities and some constraints on the choice of devices used on the server.
