Rice is the staple food of the majority of Indonesians and most of the population work as farmers. However, the amount of rice produced are still insufficient. To meet the rice needs for the society, it should increase the amount of rice production by focusing on rice field quality such as the water level rice fields. In this study a prototype rice field irrigation system is designed using AWD irrigation method by regulating open activation and closing the inlet gate and exit gate based on the age of paddy which are calculated using RTC and the height of paddy water measured using ultrasonic sensors. The system also designed to receive input from the age of paddy and deactivate the system from the mobile application through the ESP8266 module. Test results from this system can measure water level with accuracy of 95.68% and read real-time time with 98.67% accuracy. The servo motor NFC DS04 works to open the door with a duration of 60 seconds and closes the door with a duration of 56 seconds. The paddy irrigation regulating system can regulate the water level with a success percentage of 81.48%. The system can receive input and deactivate the system with a percentage of success of 70%.

Exercise provides many benefits for the body. For someone who has heart problems, exercise should be aligned according to the heart condition. This paper proposes to report a system of monitoring heart rate in real time based on Android by using photoplethysmograph (ppg) signals to provide early warning in anticipation of fatigue during running exercise. The contribution of this study is an algorithm to define the level of fatigue when a user running exercise. During exercise, the heart rate monitoring system in the application will record heart rate data in real time and give a warning message in the form of vibration on the user's smartphone device when the heart rate is too fast or over the maximum limit. Monitoring heart rate using an Android application and easy pulse plug-in sensor. The easy pulse plug-in sensor is placed on the user's fingertips to record heart rate data using photoplethysmograph (ppg) signals when the user do the exercise. The heart rate detection by the easy pulse plug-in sensor is done in the microcontroller, and then the heart rate data is sent to the smartphone via Bluetooth communication media. System testing is done by running exercise using a test scenario in the form of variations in age, running speed and length of running period to see the effect of physical activity on the number of heart rates. The test results show that the accuracy of heart rate detection is 95.923% and the android application can give a warning when the user's heart rate more than the normal limit when running.

One symptom of Transient Ischemic Attack (TTA) or mild stroke is a loss of balance that makes ones easy to fall. The attacks on TIA usually occur in a short time and require immediate medical help. This study aimed to develop movements monitoring system and detector of fall for TIA sufferers using accelerometer and technology of internet of things (IoT) technology. The contribution of this study is to define ten falling movements with a decision tree algorithm. These movements are 1). Not moving, 2). Walking, 3). Standing up, 4). Sitting down, 5). Sitting, falling to the right, 6). Standing, falling towards the right, 7). Sitting-falling to the left, 8). Standing, falling to the left, 9). Sitting, falling to the front, 10). Standing, falling forward. An accelerometer is used to detect patient movement through linear and angular acceleration. The definition of movement and state of falling patients is determined by the decision tree algorithm. When a TIA patient falls, the system will send a notification to the family via the Smartphone application about the location where the patient fell. The IoT concept is applied to build this system. This test uses a test scenario of nine positions and movements of patient. Test results show that the system has detected 81.48% falls in TIA patients and can send notifications to the patient's family with a response time of 2.65 seconds.
