An incubator is a place designed to maintain a certain temperature condition. Incubators are often found in hospitals and farms. In hospitals, the Incubator functions to warm newborns, or premature babies. On farms, this incubator is usually used for egg hatchers and as a place for newly hatched chicks. Incubators are usually in the form of a room or box (box) of a certain size. In this research will be designed a prototype to modify the infant incubator by adding sensors to regulate the temperature and control using a Arduino microcontroller. This incubator has a measurement system and temperature regulation using LM35 sensors, heaters and fans as actuators that can cool the incubator room with Arduino as controlling. Temperature setting will be monitored by LABVIEW. In the Arduino system a program can be set up that can adjust the temperature . The temperature required by the premature baby, so that it can maintain the stability of the temperature. If the temperature in the incubator is smaller than the temperature setting, the heater will turn on and the fan speed will decrease to increase the temperature according to the settings entered. If the temperature in the incubator is greater than the temperature setting entered, the heater will turn off. The results showed that the linear regression value between the temperature values with the ADC value of y = 0.4883x with a determination coefficient of 1, while the linear regression value between the temperature with a voltage value of y = 99.481x with a coefficient of 0.9984.Keywords: Infant Incubator, temperature sensor, LM35.

A good and feasible centrifuge is needed in the world of health, therefore a digital tachometer is needed to calibrate a centrifuge. Digital tachometer is a measuring instrument used to measure the rotation speed of a motor. This tachometer will be tested to function by being compared to using Digital Laser Photo Tachometer. This tachometer will display the number of rotations per minute of a motor according to the speed setting on the centrifuge using the output of this E18-D80NK sensor which will later be processed by the Arduino Nano. As for this feature charger and data storage mode, so that user can save the data of measurement results on SD Card, and beside that user can also be a way of charging when after usage or before usage. At testing the tool used point settings 1000, 2000, 3000, 4000, 5000, and 12000 RPM. Based on the measurement results of centrifuge using tachometer module and comparison tachometer have average percentage of error varying at each setting point. The smallest error 0.8% at the setting Point 3000 RPM, while the largest error 4.9% at the setting point 1000 RPM. The Tacometer error value on this Centrifuge measurement is still within the tolerance limit of ± 10%

Legged robots have attracted the attention of researchers because of their superior adaptation to complex environments compared to wheeled robots. Legged robots are divided into 2 (two) legged Humanoid robots, 4 (four) legged robots, 6 (six) legged robots, and other robots with more legs. Legged robots are robots that can be more adaptable to the terrain compared to wheeled robots in the case of their use in land exploration activities. Although functionally legged robots are more superior, legged robots have their own problems, namely motion control which is more complicated than wheeled robots, therefore the right method is needed to be implemented on the robot.. In this research discusses a 4 (four) legged robot designed in order to move using the inverse kinematic equation on the legs and the body of the robot which is integrated with the MPU6050 gyroscope sensor based on the Hybrid Fuzzy-PID control system. The purpose of this research is to develop a Fuzzy-PID control system that stabilizes the setpoint position in the 4 (four) legged Robot movement system. Fuzzy PID is a combination of PID control and fuzzy logic, where PID control is used to stabilize the system and fuzzy logic is used to improve the system performance. In this research, the Fuzzy-PID control system is developed using the Mamdani (Min-Max) method. The system is later tested by observing the robot's movement response to changes in the gyroscope sensor values. The results obtained were able to get an average output error up to 0.173333% during the response test to the pitch axis of -15°, but in several tests also get the response results that have a considerable error rate is up to 27.31% during the response test to the roll axis of -5°. From the test results of hybrid Fuzzy-PID control, it is obtained that the robot is able to make movements or responses to its stable point by giving reference to the x (roll), y (pitch) and z (yaw) axes where it can be analyzed that the response to the x (roll) and y (pitch) axes will affect the angle of the tibia and femur servo joints, while the response to the z (yaw) axis will affect the angle of the coxa joint servo.

ABSTRAK Robot berkaki telah menarik perhatian para peneliti karena adaptasinya unggul terhadap lingkungan yang kompleks dibanding robot beroda. Robot berkaki dibagi menjadi robot Humanoid berkaki 2(dua), robot berkaki 4(empat), robot berkaki 6(enam), dan lainnya yang berkaki lebih banyak.Robot berkaki adalah robot yang lebih adaptif terhadap medan tempuh dibandingka robot beroda dalam kasus penggunaannya pada kegiatan eksplorasi daratan. Walaupun secara fungsional robot berkaki lebih unggul, robot berkaki memiliki permasalahan sendiri, yaitu kontrol gerak yang lebih kompleks dibanding robot beroda, maka dari itu dibutuhkan metode yang tepat untuk diterapkan pada robot. Pada penelitian ini membahas tentang robot berkaki 4(empat) yang dirancang untuk dapat bergerak dengan menggunakan persamaan inverse kinematic pada kaki maupun badan robot yang diintegrasikan dengan sensor gyroscope MPU6050 berbasis sistem kendali Hybrid Fuzzy-PID.Tujuan dari penelitian ini adalah mengembangkan sistem kontrol Fuzzy-PID untuk menstabilkan posisi setpoint pada sistem pergerakan Robot berkaki 4(empat). Fuzzy PID adalah gabungan dari kontrol PID dan logika fuzzy, dimana kontrol PID digunakan untuk menstabilkan sistem dan logika fuzzy digunakan untuk memperbaiki performa sistem. Pada penelitian ini sistem kontrol Fuzzy-PID dikembangkan dengan menggunakan metode Mamdani (Min-Max). Sistem ini kemudian diuji dengan mengamati respon pergerakan robot terhadap perubahan nilai sensor gyroscope. Dimana diperoleh hasil mampu memperoleh rata-rata kesalahan hasil keluarannya sampai dengan 0.173333% pada saat pengujian respon terhadap sumbu pitch -15°, namun dibeberapa pengujian juga mendapa tkan hasil respon yang memiliki tingkat kesalahan yang cukup besar sampai dengan 27.31% pada saat pengujian respon terhadap sumbu roll -5°. Dari hasil pengujian kendali hybrid Fuzzy-PID diperoleh hasil robot mampu melakukan pergerakan atau respon untuk menuju titik stabilnya dengan pemberian acuan terhadap sumbu x(roll), y(pitch) dan z(yaw) dimana dapat dianalisa bahwa respon terhadap sumbu x(roll) dan y(pitch) akan mempengaruhi sudut servo sendi tibia dan femur, sedangkan respon terhadap sumbu z(yaw) akan mempengaruhi sudut servo sendi coxa.

Gout is the final metabolite of purines. Purines are part of the nucleic acids found in the nuclei of body cells. Increased gout can cause rheumatic pain in the joint area and is often associated with extreme pain for those exposed to the disease. Doctors need to monitor so that they can assist patients in monitoring and treatment. Gout detection devices are only available in hospitals, clinics, health centers, laboratories, and equipment that was previously portable but could not be controlled directly by a doctor. The purpose of this study is to help make it easier for doctors to monitor patients with gout remotely or telemedicine via the internet. The research method uses blood to determine gout levels using the Internet of Things. Data acquisition is carried out with a resistance sensor (Authocheck) which is processed by the Arduino microcontroller. The processed data is then sent to the ESP8266 web server via WiFi. The use of the Internet of Things as a data transmission method for online use does not require human-to-human interaction. The sensor resistance value in the analog range obtained is 441.03 to 782.32 with a sensor voltage of 1.91 to 3.82 volts. The measured gout level is between 4 mg/dL and 8 mg/dL. The percentage of measured data with an average accuracy of 95.74% and an average error rate of 4.26% for the seven test data. Data is displayed directly on the device's LCD screen and on a web server that sends data from the ESP8266.
