Abstract

Three wheeled omnidirectional robot has been used in industries and academics fields because its ability to move freely and simultaneously both rotation and translation. Free movement in this robot is assisted by omni wheel which consists of wheels and rollers. So, the movement of this robot is a combination of wheel and roller rotation. At present, the task given to the mobile robot is increasingly complex, so it makes microcontroller’s workload heavier. A microcontroller’s workload could be lightened by master-slave configuration to divide the microcontroller’s tasks. The wheel rotating speed control system uses a pid controller to obtain a fast and stable wheel speed response. The PID parameters, kp,ki,kd were obtained by using the hand tuning method. The testing results shown the average error of robot direction is 4,3750 and the direction of the robot’s face changed 5.750.

Abstract

Hemoglobin is important part of red blood cell to transport oxygen and carbon dioxide. Hemoglobin concentration in the blood can be used as physical condition parameter. A low hemoglobin level is called anemia and high hemoglobin level is called polycythemia. WHO has determined the anemia cut off level of hemoglobin concentration based on age, sex, and condition (pregnant or not). Currently, accurate and reliable hemoglobin concentration measurement uses invasive methods such as cyanmethemoglobin  and  automated  hematology  analyzer.  But these methods are expensive, not real time, high infection risk, and need special techniques. Non-invasive methods offer a better alternative because it has low infection risk, instant result, and portable in size. This work developed a non-invasive hemoglobin measurement for anemia diagnosis based on optical spectroscopy. The system utilized LED and photodiode as optical sensor placed on the fingertip. Photodiode just could obtain DC component, so the signal conditioning circuit which consisted of HPF, LPF and amplifier was used to obtain the AC component of the signal.  This system used microcontroller to control the operation of the hardware and to calculate the hemoglobin concentration.Hemoglobin is important part of red blood cell to transport oxygen and carbon dioxide.

Abstract

Poultry industries encounter problem in produce day old chicken (DOC). Poultry industries usually produce DOC using egg incubator. Egg incubator must have high accuracy in reading environment temperature inside the machine. The temperature environment inside the egg incubator machine needs to keep in range 36°C - 40°C. On the other hand, hatcheries and chicken coop usually not in one place. Poultry industries require applied technology to solve this problem. This problem can be solved by using internet of things. But internet of things can be so expensive. This research is aim to implement monitoring and controlling temperature inside egg incubator prototype while using low-cost communication technology. Research result showed that the control system could maintain egg incubator prototype temperature in optimal range with an accuracy of 99,63%, 99,83%, 99,97%,99,64%, and 99,37% when reading a temperature of 36°C, 37°C, 38°C, 39°C, and 40°C respectively. This research implements Long Range (LoRa) technology for monitoring system. Different with internet of things technology, point to point LoRa communication does not needs payment to communicate but still provide wide area communication. According to research result, point to point LoRa communication provide good performance in sending temperature data in range area 50m, 100m, 150m, 200m, 250m, and 300m with good average Receive Signal Strength (RSSI). This research can conclude proposed egg incubator can keep temprature in optimal range. Proposed incubator also can communicate properly to send data temperature for monitoring temperature.

The current watering still uses a manual system which will result in a loss of time and effort. In addition, manual watering also wastes water and can make plants wither. In this study, a system is proposed to help maintain the humidity of chili plants by using gravity drip irrigation techniques that can be monitored online and in real time on an android application and google spreadsheet. The test results show that this system is able to maintain soil moisture at a value of 60%-80% with the volume of water used as much as 26.67 milliliters/minute. The average results of all sensor and servo motor accuracy tests produce a fairly good value with an average error of 1.96% and an accuracy of 98.04%. Furthermore, the QoS test results for delay are in the good category with an average of 177.99 ms and packet loss is in the very good category with a value of 0.02%.Keywords: Drip Irrigation, Humidity, IoT, Firebase, Spreadsheet
