<![CDATA[In this study, a monitoring system was generated to send data about temperature, humidity, and ammonia gas from a dairy cow cage. This system also provides notifications and recommendation to the owner to carry out certain actions based on data obtained from the dairy cow cage. This system consists of three main components, namely the web server monitoring devices and an application on mobile device. Furthermore, monitoring devices consist of a microcontroller, DHT22 sensor, MQ-135, and ESP266. The microcontroller sends data to the web server and the device moves continuously to notify the state of the dairy cage. From the test results, it is known that the system can send data correctly to mobile devices and web servers. Notification of abnormal conditions is given in an average of 39 seconds.]]>

<![CDATA[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%.]]>

<![CDATA[Body’s height and mass measurement usually are measured with a different instrument without a knowledge to know the ideal body mass index (BMI). Ideal BMI is related to our health condition especially for people who do exercise. Usually people just guess the BMI from a visual condition that sometime give a false measurement. This paper proposes a device that can measured ideal BMI based on Brocha method based on microcontroller. The body’s height will be measured using ultrasonic sensor while the body’s mass will be measured with a load cell. The results show that the proposed device can predict the BMI well. The height measurement has a successful rate of 80%.]]>

<![CDATA[The purpose of this research is to detect whether a person has diabetes mellitus or not. In people with diabetes mellitus uncontrolled will result in a decline in the rate of saliva that results in bad breath. The system uses the sensor TGS 2602 and MQ 4. It's function is to detect the levels of Hydrogen Sulfide and Methan in a person’s breath. The decision is made by using the neural network with a backpropagation method. The result for 5 (five) tests of diabetes mellitus samples can be detected with a success rate of 80%, whereas using random samples, the test detected with detected with a success rate of 80% samples that didn’t contain diabetes mellitus. This system could provide a solution for testing if a person is suffering from diabetes mellitus]]>

<![CDATA[Landslide is one of the most frequent disasters in Indonesia, especially in hilly areas, valleys, and volcanoes. Geographical conditions that are generally mountainous areas and have slopes make the soil unstable. As a result, when the movement of the land becomes easy to slide. Ground shifts and excessive water content are the main causes of landslides. The landslide disaster can cause many losses, such as to cause loss of life, can disrupt transportation facilities, damage agricultural land, and various other consequences. In this study used sensor MPU6050 and Soil Moisture and NodeMcu sensors to provide early warning of landslides. Linear acceleration is detected by using MPU6050 sensor and will define the ground movement based on the scenarios developed in this study. Soil moisture sensor detects soil moisture. The result of soil movement detection and soil moisture is stored in file storage. When ground detection and soil moisture is greater than 51%, the alarm alert is sent to the user's smartphone with a 100% success percentage.]]>

<![CDATA[This study aims to create a security system that can work when motorcycles are parked or are being driven. Most congenital motorcycle security systems work only when the motor is parked, such as the security of the ignition key and the handlebar lock. In fact, not infrequently theft is done by robbing a motorcycle that is being driven by owner. Then made a system using Arduino microcontroller platform, GSM SIM800L module and mobile device. The system created consists of three MODE, the MODE PARKIR, MODE JALAN and MODE MANUAL that can be selected through mobile devices with Bluetooth connection. In MODE PARKIR there are two sensors that detect the theft action, the vibration sensor SW420 and Voltage sensor. If the ignition key is successfully broken or there is a motorcycle on the motorcycle GSM SIM800L module will give notification in the form of SMS and phone call. For Roadside mode the motorcycle ignition system will be activated automatically and the owner can directly use the vehicle without having to manually activate the ignition. When the motorcycle is seized the owner can turn off the vehicle engine by pressing the Stop button on the mobile device and GSM module SIM800L will send the coordinates of the nearest BTS.]]>

<![CDATA[Robotics is a field of science that is developing rapidly, One of Robotic field is a wheeled robot whose sample application allows robots to explore automatically. But today, more research on the application of artificial intelligence in robot control is aimed at obtaining sophisticated kinematic control. In this final project, a wheeled robot will be designed with the ability to detect obstacles. As a control object is a robot tank that both wheels use a belt wheel and have a separate DC motor. A fuzzy logic controller functions to regulate the speed and direction of the robot's motion based on the input of the ultrasonic sensor. The design of robots based on the embedded microcontroller is designed using the C language. From the test results, that fuzzy logic can be embedded in the ATmega328 microcontroller control unit on Arduino Uno, so that a robotic motion can be avoided that can avoid obstacles properly. The closer the obstacle distance results in the sharpening direction of the robot and the more rigorous robot movement.]]>

<![CDATA[Broiler chicken is a species of chicken that have high productivity. In order to get a good quality of chicken, good treatments of the breeding factors is needed, so the chicken will not easily infected by diseases. Gastrointestinal diseases are common disease that infects chickens. The mortality level caused by gastrointestinal diseases is considered high. This study is designed to address the problem by developing a system using the Naive Bayes algorithm. 60 chicken data samples were used, and the result shows that Naive Bayes might be used to detect gastrointestinal diseases among chickens with accuracy level of 93.3%. The number was confirmed by using confusion matrix evaluation method, and gave same level of accuracy compared to the expert judgments.]]>

<![CDATA[People in general have a desire to live a healthy life. One way to keep health is by consuming herbal drinks, one of them is known as jamu. Jamu which is commonly found is "jamu gendong" which is a home-based herbal product that is marketed in the form of liquid in the bottle. When buying jamu, the seller will mix various types of jamu by pouring jamu from each bottle into a glass according to the buyer's request. However, mixing several types of jamu is carried out using the seller estimate, so the dosage of several types of jamu to the glass will vary according to the pouring. The purpose of this research is to make a arduino Mega based automatic jamu beverage mixing system. This system uses an LDR sensor to detect the presence of a glass with a resistance value read by an LDR sensor is > 500 ohm and a DC motor can move by the stirrer. The selection of the jamu menu's is done by pressing the keypad button from the code '1' to the code '8'. After the menu is selected, the jamu will flow to the glass and the volume of jamu will be calculated using a water flow sensor that uses multiplier values. For the volume of 150 mL is used to multiplie factor 3.7 , for the volume of 100 mL is used to multiplie factor 2.9 , and for the volume of 50 mL is used to multiplie factor 1.2.]]>
