Abstract

Along with the development of science and technology, problems often occur that threaten security at home. These problems originate from a level of security that does not meet security standards at home. Various problems that can threaten home security conditions are fire hazards that can be caused by neglect of home temperature regulation and electrochemical equipment that is uncontrolled by the homeowner or thief danger that can easily enter the house. The design of the home security system prototype is programmed and controlled by the NodeMCU ESP-8266 to transmit all data from sensor readings to the interface on the Cayenne dashboard. PIR sensor (HC-SR501) has a digital output, if the sensor detects a movement, the NodeMCU ESP-8266 will give a logical value of one. Gas sensor concentration (MQ-02) in testing has an average difference of 2.79 ppm (part per million). The reading results of all sensors will be measured through the Internet of Things interface displayed on the Cayenne dashboard, the simulated gas concentration with gas matches with the difference results, test results and analysis results of 2.79 ppm (part per million) and if the gas sensor (MQ -02) Exceeds the specified parameters, the buzzer will sound. PIR sensor testing (HC-SR501) will work optimally by human movement if at an angle of 45˚ because the success rate is 100% in ten experiments and in the 90˚ angle the success rate is 80%.

Abstract

Depo Lokomotif is a work unit that is responsible for locomotive reliability in running the railroad transportation operational business. According to internal monthly report data from February 2019 to February 2020, there were 6 cases of weak locomotive power disruptions that caused operational delays. Analysis was carried out on the CC203 locomotive propulsion system in order to obtain the value of the power reduction in one case of disturbance by comparing the output value against the set standard value. Using mathematical calculation methods from the applicable equations and processing the data on MS.Excell. From the results of the study, the cause of the decrease in locomotive power is due to a decrease in the excitation value so that it affects the output value of the Main Generator at each Notch and has an impact on the motor traction power supply also decreases. The Main Generator can only issue a maximum Horse Power at Notch 8 of 1389.96 HP from 1985.31 HP with a decrease of 595 HP. The electric motion of the generator exciter has the largest decrease at Notch 7 of 6.02 volts from 30.48 volts to 24.46 volts. Motor traction can only output a maximum terminal power of 985.067 Watt from 1407 KWatt.

Abstract

One of the effects of reduced transformer life is the frequent occurrence of disturbances, disturbances that can occur in the form of contamination of insulating oil which has an impact on transformer damage. To reduce the damage, a research was carried out, in this study it was carried out to see the effect of water contaminants contained in the insulation of transformer oil using the Breakdown Voltage method by looking at the value of the translucent voltage. There are 2 types of insulating oil used during testing, mineral, and vegetable oil, while the test equipment used is the BAUR Oil Tester DPA, with the standard IEC 60156:2018 test equipment. Which is adapted to the standard specification SPLN 49-1:1982 which states that new oil has a breakdown voltage value of 30 kV/2.5 mm. The results of the test show that the breakdown voltage value is influenced by water contaminants where the more contaminants contained, the faster the breakdown voltage value will decrease. This research can be an indication to maintain the transformer resistance.

Abstract

Measuring the number of pulses has been used in the medical world to determine stress, relaxation, physical fitness levels, and other medical conditions. Due to the importance of checking heart rate, it is necessary to have a portable and practical heart rate measuring device so that patients with heart disease will be easier to be monitored. The device is equipped with pulse sensor to measure the heart rate in real time and provide a beats per minute (BPM). The results of normal heart rate conditions, bradycardia, and tachycardia can be monitored using mobile device application based on the measured BPM. This can be seen as output voltage generated by the pulse sensor. This pulse sensor has an average percentage error of 1.77% and deviation of 2 that is relatively small compared to standardized devices. The device is connected to the mobile application by Bluetooth which the coverage is 11 up to 45 meters depends on the obstacles.

Abstract

Manufacturing process was important in the development of antenna technology in order to obtain the antenna optimal performance. One of the approaches to increase the antenna performance was to use a natural dielectric material. In this research, a waveguide antenna was designed by inserting a natural dielectric material, an FR-4-Epoxy (? = 4,3 in the simulator) into a waveguide with a width of 72 mm, a height of 34 mm, and a length of 50 mm. The properties of the mode waveguide antenna were modified by slightly varying the position of the dielectric material and adding an initial thickness of 1.6 mm. The excitation of the waveguide was configured using mode. The Observed paramters in this research are (return loss) and radiation parameters (gain and directivity). On the simulation shows that the best performance of the waveguide antenna was obtained when the dielectric position is 2 mm from the connector and thickness 3,2 mm. The simulation also generates the parameter of -22,8 dB with gain and directivity was 5,77 and 1,799 respectively at a frequency 3 of GHz while from measurement the frequency was shifted at 3,15 GHz with -23,05 . The result of this research shows that the addition of dielectric material to the waveguide antenna as a resonator will affect the antenna parameters this is due to the nature of the dielectric material which has a special permittivity value that changes the nature of the medium of wave propagation propagating on the antenna. From the observations in the simulation stage, the closer the position of the material to the connector and the thicker the material, the better the return loss, even though it slightly shifts the working frequency of the antenna from the initial frequency.

Abstract

The development of medical equipment with advanced technology can provide convenience in providing services to the community. One of the equipment that is in the hospital and most often used is an IV. In its use, manual infusion is used to determine the volume of the infusion and must be monitored every hour or even minute by the nurse. This is considered quite difficult, especially in the era of the Covid-19 pandemic where minimal interaction is required from 2 individuals. This is done by utilizing sensor technology to monitor the patient's condition so that the frequency of the nurses checking the condition of the infusion is getting less. Therefore, in this research, manufactured of an infusion monitoring system using aweight sensor (Load Cell) based on the ATMEGA 328 microcontroller was carried out. The sensor of this monitoring system uses a Load Cell Weight Sensor with the HX711 module which is integrated into the ARDUINO UNO MCU. The output of the system is displayed on a 16 x 2 mm LCD as well as a Macro Excel which will display the percentage value of intravenous fluids in the PC and real-time automatic data logging into the macro excel. The infusion used uses Nacl fluid infusion. The test results of the system as a whole show that the data for measuring levels (%) of intravenous fluids can be sent and displayed on the LCD and PC. The incoming data is converted into a table at certain time intervals according to the user's choice into the operator. The experiment was carried out 10 times by looking at changes in the contents of the infusion fluid over time in 11 stages where the LED lights up when the weight of the infusion reaches 40 - 46 grams. Then, the buzzer and LED have turned on when the weight of the infusion is less than 5 grams. From the experiment, it can be concluded the 10% setpoint alarm works well, i.e. when the infusion load is less than the 1% set point, the buzzer and LED will light up until the intravenous fluid is replaced with a new one.

Abstract

The increasing demand for electric energy will always coimcide with increasing equipment performance at electrical substation. Power Transformer is one of the tools that really feels the impact, namely the increasing temperature of it is conductor in the form of transformer windings. That is the reason why the transformer has insulation in it, in the form of cellulose paper and transformer oil. To know the indication of failure on the transformer, we can test one of the transformer insulation, namely transformer oil. By doing the DGA testing and Breakdown Voltage of Transformator Oil Testing. After doing the DGA test by analyzing the testing result using TDCG, Key Gas, Doernenburg Ratio, Rogers Ratio, and Duval Triangle Methods. It can be seen that transformer 1 and 3 have experienced a failure indication in the form of temperature failure (Thermal Fault). It can be seen from the high content of methane and ethane gas. And after testing the voltage of the transformer oil breakdown, it can be seen that the condition of the transformer oil breakdown voltage 1 and 3 in the first test are still in good condition. Contrast with the second test, value of the breakdown voltage from both transformer are very bad. That is because the distance between the time of sampling with the testing is very far away and it causes many contaminans in the transformer oil.
