Abstract

Radio frequency Identification (RFID) is an automatic identification technology that transmits data via radio frequency electromagnetic ranging is applied to various fields, replacing the other automatic identification system. However, RFID has a fatal weakness, that is very vulnerable on collision data, that caused interference between signals the reader to each other. In this problem required an anti-collision algorithms to resolve the collision. in this study the algorithms used are Distributed Color Selection (DCS). DCS is anti-collision algorithms based Time Division Multiple Access (TDMA) that uses the specified time interval called timeslot. Each reader choose timeslot each and when the system began, the reader will only be active in accordance with selected timeslot. The system was tested using the RFID reader module MFRC522 13.56 MHz and RFID tags 13.56 MHz with the different variation number of readers and the total number of timeslot customized with number of readers. RFID is connected to the Arduino Uno microcontroller and the results are displayed on serial monitor Arduino IDE which then calculated the efficiency of identification works. The result of calculation and testing can be inferred, the highest efficiency when using 2 readers for identification without the use of algorithms is 40% while using DCS is 100% Results for used 3 readers without the algorithms was 10% while using DCS is 80%. As well as using 4 readers without algorithm is 0% while using DCS is 70%.

There is a proof that own good cardiorespiratory fitness can reduce cardiovascular disease like heart attack and stroke. Therefore it's important to have good cardiorespiratory fitness. Cardiorespiratory fitness can be measured by level maximum oxygen body can take (VO2max). There is a method for prediction of VO2max without doing physical activity using heart rate rest, body weight and age (non-excercise prediction method). Measuring Heart rate and body weight for calculation VO2max with non-excercise prediction method use 2 sensors, pulse sensor and load sensor. In order to facilitate VO2max calculation and displaying attractive result, then used android OS-based devices as an intermediary by utilizing the HC-05 Bluetooth module as a medium of data exchange. Applications built on android OS based devices are also equipped with suggestions for improving good VO2max so that it can be a guide for users. Tests on sensors in VO2max measurements resulted in an error of 8.12% for pulse sensors and 0.92% error results for load sensor. The maximum effective range that can be done by the Bluetooth module HC-05 is 10 meters. The method performed can easily measure VO2max without having to do physical activity so as to facilitate in the supervision of cardiorespiratory fitness of the body.

Abstract

The method of conventional robotic arm motion is by forward kinematic, which moves by determining the time of deviation of each joint to reach a point. Unlike the forward kinematic, inverse kinematics move by determining the angle required to perform a motion. Forward kinematics is considered as method that utilizes trial and error, this method become less effective because it takes a long time. Meanwhile, inverse kinematic offers more practical solution with more complex computing calculations. With the development of microcontroller complexity on calculation inverse kinematic can be done more quickly by using parallel computing that can take advantage of all the existing cores on the microcontroller. openMP is a C ++ program directory that describes the use of application program interfaces to perform parallel computations in multiple memory environments. openMP becomes one of the programs that can be utilized to perform parallel computing. The result is, openMP able to divide the program so that the Squential program imposes its process on core 1 (30.74%). But in the parallel program the process load fairly even distributed, although it looks more burdensome to core 2 (30,7%) and 3 (20,38%). Accuracy calculation results from both methods are same, both have same nois and error that is equal to 0.4 cm from x axis, 1.5 cm from y axis and 1.06 cm from z axis. In addition, the error also occurs at the servo angle, where the average error in 1st servo is 1o, at the 2nd servo is 1.24o, and at the 3rd servo is 4.1o. When compared to speed, the parallel method performs all tasks faster than squential by 20 seconds (36.4% of the sequential time) for 4 servos and 10 seconds (22.2% of the squared time) for 3 servos.

Abstract

ABSTRACT Nowadays. the topic about energy scarcity issue becomes quite often discussed in the development of modern technologies such as wireless sensor network (WSN). From many of its implementations. WSN's main problem is about energy consumption. This is happened because the power supply of the node only supplied by a battery for its operation, so it has limited energy reserves. If one node dies, it will change the network performance in terms of routing and topology. In this study, a battery capacity measurement module is implemented on an embedded device. If the battery capacity information of the battery is known, then the approximate time of how long the embedded device can continue running will also be know, and so it can support the further development of energy savings on embedded devices. In its implementation. the module uses a resistor shuntto obtain a the value of drop voltage which is then can be used to measure the current flowing on an embedded device using Ohm's Law. When the current is known. the battery capacity can be calculated. Value processing is done by using arduino nano microcontroller. The module then provides battery capacity information in the form of percent value and the current flow value on the embedded device via LCD. It is concluded that the module can measure the current flow of the embedded device and the module can also calculates the battery capacity that used by the embedded device. The module works with a 94,56% accuracy level in measuring battery capacity.

Abstract

The advent of climbing in Indonesia can not be denied by the jump in number of climbers every year. Climbing is widely done in September through December where the moon presents its natural beauty to its maximum. But during the month, the Mountains had very cold temperatures due to the extremely high rainfall. Where very high rain rains cause some risks, especially those related to the health of climbers such as colds, injuries from power (heart, and muscle) and hypothermia. This condition often attacks climbers who do not carry complete climbing equipment, are exposed to rain and lack of calorie or other consumption. Based on that background, this study is designed to design Temperature Control on Sleepingbag as a Relief Action on Hypothermia Patients. In this research the writer uses two components namely bracelet and sleeping bag. The bracelet acts as a transformation to get data from the body which is an object then sent to the sleeepingbag that serves to warm the body of hypothermia based on the inputs obtained from the bracelet. Thesis research is intended to design and implement temperature controlling on sleepingbag as a precautionary measure for hypothermia that often occurs in mountainous areas as well as for the development of domestic industry in the field of medical devices. The results of this study indicate that the bracelet system and sleeping bag system work according to the human body condition. The bracelet system will tell the data obtained from the sensor through the LCD display, when the pulse sensor gets the body data less than 60 then the lcd will show that you are detected hypothermia. Then the user will press the button to trim data to sleepingbag to process the data with fuzzy method. Where if the body temperature is less than 35⁰C and the sleep sleeping bag is less than 28 then the sleeping bag system will unveil the heating output in the form of full nickel wire according to the rule made in matlab.
