Abstract

In telecommunication, filters are often used to pass the desired frequency. One of them is the Band-Pass Filter (BPF) which is passing signals between the upper cut-off frequency and the lower cut-off frequency. This research aims to make a band-pass filter that can pass 3 GHz frequency with a bandwidth of 200 MHz. This filter is designed with a square open-loop resonator simulated using Advanced Design System (ADS) software. The filter is made using FR 4-epoxy substrates with a dielectric constant (ε ) of 4.6 and substrate thickness (h) of 1.6 mm. Based on the simulation results obtained in the form of a comparison graph between the response of magnitude to frequency, it shows that the value of the return loss (S 11 ) parameter of -23.549 dB, insertion loss (S 21 ) parameter value of -1.397 dB, and a slightly shifted middle frequency of 2.890 GHz. Then for the measurement results obtained a parameter value return loss (S 11 ) of -16.364 dB, parameter value insertion loss (S 21 ) of -3.561 dB with a center frequency of 3.185 GHz.

Abstract

Perkembangan antena radar semakin cepat dan beragam, salah satunya adalah antena MIMO (multiple output). Antena MIMO banyak digunakan untuk teknologi 5G  karena efisiensi spectral dan fekuensi yang tinggi. Antena MIMO juga merupakan suatu sistem yang menggunakan multi antena baik pengrim (Transmitter) maupun penerima (receiver) yang bisa mengatasi kelemahan pada sistem komunikasi wireless. Penelitian ini merancang sebuah antena mikrostrip MIMO 2X2 dengan menggunakan patch bowtie untuk mengkonversi frekuensi dari 2,4 GHz menjadi 5,5 GHz dengan menambahkan dual slot segiempat dan single slot segitiga. Hasil simulasi menunjukkan penambahan dual slot segiempat dan  single slot segitiga pada patch antena bowtie dapat menggeser frekuensi kerja dari 2,4 GHz menjadi 5,5 GHz. Dari hasil simulasi antena MIMO 2X2 didapatkan nilai return loss S11 sebesar -46,5 dB, insertion loss S21 sebesar -25,2 dB, bandwidth sebesar 192,2 MHz, VSWR sebesar 1,00 dan gain sebesar 3,11 dBi. Hasil dari pengukuran antena MIMO menunjukkan perbedaan dari parameter antena 1 dan 2. Hal ini disebabkan adanya ketidaksamaan ukuran dari antena 1 dan antena 2. Pengukuran  nilai return loss untuk antena 1 yaitu sebesar -22,32 dB dan -15,63 dB untuk antena 2. Hasil pengukuran insertion loss antena 1 dan 2 memiliki nilai yang sama yaitu -43,5 dB dan untuk lebar bandwidth memiliki perbedaan nilai yaitu 50 MHz untuk antena 1 dan 100 MHz untuk antena 2. Pengukuran nilai VSWR 1 didapatkan nilai sebesar 1,96, VSWR 2 sebesar 1,41. The development of radar antennas is getting faster and more diverse, one of which is the MIMO (multiple output) antenna. MIMO antennas are widely used for 5G technology because of their high spectral efficiency and frequency. MIMO antenna is also a system that uses multiple antennas, both transmitter and receiver which can solving the weaknesses in wireless communication systems. The research designed a 2X2 MIMO microstrip antenna using a patch bowtie to convert the frequency from 2.4 GHZ to 5.5 GHz by adding dual rectangular slots and single triangular slots. The simulation results show that the addition of dual rectangular slots and single triangular slots on the patch bowtie antenna can shift the working frequency from 2.4 GHz to 5.5 GHz. From the simulation results of MIMO 2X2 antenna, the return loss value of S11 is -46.5 dB, insertion loss S21 is -25.2 dB, bandwidth is 192.2 MHz, VSWR is 1.00 and gain is 3.11 dBi. The results of the MIMO antenna measurements show differences in the parameters of antennas 1 and 2. This is due to the difference size of antenna 1 and antenna 2. The measurement of the return loss value for antenna 1 is -22.32 dB and -15.63 dB for antenna 2 The results of the insertion loss measurements for antennas 1 and 2 have the same value, which is -43.5 dB and for the width of the bandwidth has a different value, 50 MHz for antenna 1 and 100 MHz for antenna 2. Measurement of the value of VSWR 1 obtained a value of 1.96, VSWR 2 is 1.41.

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

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.
