Kontrol penyiraman berbasis fuzzy agar kadar air yang diberikan bisa akurat. Sebelum penyiraman, rata-rata kelembapan tanah pada lahan tersebut adalah 45.28% dengan nilai minimal 40%, nilai maksimal 50%. Target kelembapan tanah untuk setiap titik adalah 60%. Robot dapat menyiram seluruh titik tanam tanpa campur tangan manusia. Nilai kadar air rata-rata penyiraman adalah 62.10%, dengan nilai minimal 60%, nilai maksimal 65%.
To support fertile agricultural land, a watering process is needed so that the water content in the soil is maintained. Watering activities carried out manually require a lot of energy. In addition, the water content given by manual watering cannot be measured accurately. In this paper, we propose automatic watering with a three-axis Cartesian robot for land with a size of 3 meters x 1.5 meters with 171 planting points. Fuzzy based watering control so that the water content given can be accurate. Before watering, the average soil moisture on the land was 45.28% with a minimum value of 40%, a maximum value of 50%. The target soil moisture for each point is 60%. The robot can water the entire planting point without human intervention. The average water content value of watering is 62.10%, with a minimum value of 60%, a maximum value of 65%. In addition, also compared with the application error with the fuzzy method with the on-off method, the fuzzy method is able to produce more accurate watering with an average error rate of 2.10%, while the on-off method has an average error of 5.32% against the soil moisture target. The fuzzy method is also more time efficient in watering, which is 7 seconds to 8 seconds, while the on-off method requires a watering time of 10 seconds to 15 seconds

An aerial vehicle has actuator four brushless DC motors (quadcopter) which is operated using a remote control or automatically. An aerial vehicle commonly called a quadcopter is controlled by using ...sensor data Inertia Measurement Unit (IMU) especially gyroscope and accelerometer sensor. Motion control is a stick control with sensor data IMU as data input. The motion from the aerial vehicle is a two-dimension (2D) motion from X axis and Y axis. Data sensor IMU is read by a microcontroller and will be processed to get real data acceleration (acceleration without influenced gravitation) remotely. The distance gesture inertia and the speed at which it operates are the parameter that is converted into an air vehicle motion. Trajectory motion is changed into picture domain 10x10 pixel as the comparison with the template matching algorithm. Match motion recognition is a motion command to the quadcopter. The simple motion like vertical, horizontal, diagonal, and curve match 96% using template matching algorithm and trajectory estimation.

The system proposed in this paper comes in form of an alarm system designed to detect any fire that happen in nearby environment, using the principle of Internet of Things (IoT) and a machine ...learning logic called Fuzzy Logic. The IoT technology is used for sharing data between node-node of sensor in a network that connected to database from the main system. Sensors that have been used in this system is system is divided into 3 types, Termokopel-K for temperature sensor, MQ-2 for smoke sensor, and the last one is flame sensor. Each of this sensor will convert the input into analog voltage. After that, data from each sensor will be processed using Fuzzy Logic to determine the level of a fire before the already processed data will be sent into the owner the property where the fire is ignited or the firefighter officer using realtime database. The result of testing the system shown that there are 2 conditions that can triggered the alarm. The first one is when there is 2 "medium" state from 2 sensor, for example 31° degree from temperature sensor and 170 Part Per Million(PPM) from smoke sensor. The second one is when there is "extreme" state from the sensor, for example, flame sensor output is 115 ADC. The increasing number in integrated sensor will increased the accuracy and computing time for environment data while maintaning the reliability of the decision taking process.
Kontes Robot Terbang Indonesia (KRTI) Flight controller division has a mission to independently make an unmanned aerial vehicle (UAV) controller. UAV controllers are usually made by non-local ...manufacturers, who have a package between the controller and the aircraft. Due to limited pins and specific functions, most controllers cannot adapt to user requirements. For this reason, in this study, we made a UAV controller with a more significant number of pins that can be programmed independently. Main Controller is a master board device used to control the stability of the UAV when flying. The main controller has been designed specifically for certain products so that the UAV cannot be modified. In this study, it is proposed to make the main controller that is specifically designed to fly a Quadcopter UAV. Movement control for quadcopter stability when flying using the Proportional Integral Derivative (PID) method. The main controller has a function that is to regulate the entire course of flight on unmanned vehicles. PID control can adapt to changes so that the system becomes stable. The PID control on the Main Controller is intended to balance the quadcopter concerning its orientation angle. The Main Controller is also tasked with recording data from sensors such as the Inertial Measurement Unit (IMU) and reading data from the remote. The controller successfully flew the quadcopter with a P value of 0.245, an I value of 0.0139, and a D value of 0.0085.
This paper presents a quad-plane tilt-rotor innovation, representing an advancement in Unmanned Aerial Vehicle (UAV) design. The quad plane boasts improvements in crucial aspects, including motor ...placement, motor count, airfoil selection, vehicle typology, and wing and tail configurations. One of the standout features highlighted in our study is its ability to conduct mapping designed explicitly for detailed plant health analysis. What sets it apart is its take-off capability that eliminates the need for launch areas and provides unmatched flexibility during deployment. When operating in fixed-wing mode, the quad plane excels in surveillance missions by ensuring data recording is automatically stored on an SD Card to maintain data integrity from take-off to landing. We employ a PID control method further supported by an IMU sensor to ensure stability during flight control. Integrating a GPS guarantees accuracy by processing satellite-derived radio signals to determine latitude and longitude information. With a flight duration of 15 minutes and reliable control outcomes, the UAV is a game changer in aerial surveillance applications. The quad-plane tilt rotor is more than a technological achievement; it has the potential to completely transform agricultural methods in Indonesia, tackling the issues of diminishing yields and rice production. Our research indicates that this unmanned aerial vehicle (UAV) is on the verge of establishing benchmarks in monitoring and analysis.

Accidents can happen in many kind of public transportation to all people. This main of this kind of accident is evacuate process of transportation accident like plane and ship, meanwhile the location ...of accident can not reach, in case like aircraft accident at mountain forest and shinking of ship in the middle of the sea. Exploration in the accident area will be difficult with terrain to access it from rescue team. Therefore UAV is needed, UAV must have capability to hover at deep forest and can cruise in the middle of ocean, so the rescue team can easily find it. The author design a quad plane with an estimation of the plane's total weight is 4400 gram and have ability to hover using four vertical motor and cruise using one horizontal motor that placed in the behind of UAV. Whereas to make transition from hover mode to cruise mode it requires an airspeed sensor as the parameter to make transition so than the plane will not lose the lift force. From the results of flight tests, quad plane can make the transition from QHOVER mode to FBWA at 10 m/s, with an altitude at 34 meters, a flying distance of quad plane at 188 meters, and a maximum speed of quad plane is 25 m/s. The quad plane also able to release the payload in the form of first aid which is useful for providing first aid to survivors.
