Dari ulasan di atas penulis mencari pemecahan masalah bagaimana membuat rancang bangun robot menggunakan sistem navigasi berbasis Global Positioning System dengan metode waypoint yang bisa memandu disabilitas netra di lingkungan terbuka dengan mengasumsikan ditemukan adanya halangan atau lubang. Dalam penelitian ini menggunakan Linkit ONE yang dilengkapi modul GPS sebagai penentu letak posisi ordinat bumi, ditambah dengan modul kompas untuk mengetahui arah robot dan sensor rotary encoder untuk meminimalkan eror posisi robot. Ada dua kali pengujian dengan empat titik waypoint yaitu, pengujian saat tidak ada halangan dan lubang serta pengujian saat ada halangan atau lubang. Hasil pengujian pertama didapatkan eror rata-rata waypoint -1 0,54 meter, waypoint -2 1,2 meter, waypoint -3 1,9 meter dan waypoint -4 1,7 meter. Sedangkan hasil pengujian ke dua didapatkan eror rata-rata waypoint -1 1,26 meter, waypoint -2 2,18 meter, waypoint -3 2,52 meter dan waypoint -4 2,44 meter. Jadi, robot pemandu disabilitas netra dengan metode waypoint ini memiliki akurasi cukup baik di mana nilai eror rata-rata robot di bawah radius 2 meter jika tidak ada halangan atau lubang dan di bawah radius 3 meter jika ada halangan atau lubang.","PeriodicalId":30766,"journal":{"name":"Jurnal Rekayasa Elektrika","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48277027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABI measurements are essential because, generally, patients are not aware of having PAD due to no significant signs and symptoms. Type 2 Diabetes Mellitus Patients tend to have PAD, which increases the risk of cardiovascular and mortality. Therefore, the measurement of ABI regularly is needed to prevent PAD. Early detection and regular monitoring of PAD by measuring ABI can avoid foot complications, such as injuries, gangrene, and amputation. The standard method to measure ABI is using Doppler. Unfortunately, not all health care providers have Doppler because it is an expensive instrument and relatively difficult to use. The purpose of this study is to design a simple and easy Prototype to measure ABI by using pressure sensors. Two pressure sensors measure the systole of blood pressure in the arm and leg to get the ABI. This study’s sample is 20 people consisting of 10 healthy people and ten diabetes mellitus patients. The result shows the ABI prototype has an error of 0.53% with an accuracy rate of 99.47%. It is indicated that the ABI prototype can be used for diagnosing PAD.","PeriodicalId":30766,"journal":{"name":"Jurnal Rekayasa Elektrika","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48722714","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During flying the mission autonomously, communication between the UAV and the Ground Control Station (GCS) must be in good and stable conditions. The GCS can well receive the telemetry data and payload sensor data carried by the vehicle. Conversely, any inconsistency parameters can be corrected by the GCS before transmitted to the UAV. Therefore, the role of the antenna is crucial to avoid signal loss during the communication process. This study focuses on GCS’s antenna. By designing the Yagi type antenna with the optimization of the distance, the number of directors, material, and shape of the reflector through CST simulation. The best option chosen is the Yagi antenna with the same distance between directors, seven directors, copper material, and flat reflectors with a VSWR of 1.1134, return loss -25.411 dB and 10.7 dB of gain. The measurement result after fabrication is the VSWR of 2.165 and the return loss of -8.677 dB.

A number of stages include the manufacture of the conveyor system unit, the electrical system, PLC programming, and performance measurement. The conveyor unit assembling was processed by installing the conveyor belt, dc motor, pneumatic cylinder, solenoid valve, and sensors. The electrical system is an integration of the Mitsubishi FX1N-24MR PLC, switched-mode power supply, miniature circuit breaker (MCB), dc voltage regulator circuit, relays, digital counters, pushbuttons, and selector switches arranged in a 20 x 30 x 15 cm panel box. Mitsubishi PLC system programming is based on algorithmic determination and ladder diagram arrangement assisted by GX Developer (GX Work). Performance measurement in the form of pulse readings is carried out by setting and manufacturing ladder counters and shift registers to count the number of pulses for each material and the accuracy of sorting when the material is detected simultaneously. The system performance is indicated by pulse reading accuracy and sorting timing accuracy. The reading of the pulse from the proximity switch affects the counter calculation to activate the pneumatic cylinder unit in sorting. Sorting for material-A takes 11 pulses, while for material-B, it takes 19 pulses. The synchronization measurement functions when an error occurs in the system in order to maintain the input received is the same as the output in the PLC-based control system.

Ultrasonic sensors are devices with minimal risk in their use and are quite often used in non-destructive testing and evaluation processes. Low frequency ultrasonic (<200kHz) has been used in the testing and evaluation process in several scientific fields. Improving the test capability of low-frequency ultrasonic measurement instruments while remaining efficient and affordable is the core of this research. Increasing test capability and efficiency by adding five test points to a low-frequency ultrasonic measurement instrument for underwater inspections have been carried out by engineering a trigger signal generator that transmits 35kHz signals at 50V voltage proven to improve the quality of the echo signal received when compared to using trigger signal sourced directly from the wave generator device, the use of a pre-amplifier module on the receiver side of the echo signal is proven to be able to increase the voltage level of the echo signal and improve the reading value of the received echo signal, as well as the signal coupling mechanism built in this study, proved to be adequate to increase efficiency multipoint testing using one ultrasonicbased testing instrument.","PeriodicalId":30766,"journal":{"name":"Jurnal Rekayasa Elektrika","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44678440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This variation causes power quality decrease even damage the equipment. Voltage variations that often occur are short and long duration. The variation consist of 6 types namely Interruption, Sag, Swell, Sustained-Interruption, Undervoltage, Overvoltage. To facilitate repairs when there is a voltage variation in the electric power system, it is necessary to have an identification that can detect and distinguish any interference that occurs. Therefore, this paper proposes a fuzzy logic method for identifying types of voltage variations. This type of voltage variation identifier requires a disturbance simulator as a voltage source with varying values. To distinguish between short duration and long duration disturbances, is the time duration of the disturbance appears. The design of the voltage variation identification algorithm uses the sugeno fuzzy inference system with 2 inputs namely magnitude vrms and timer, and 1 output is the type of voltage interference. Moreover, prototype design using AMC1200 voltage sensor, microcontroller, and display. To validate the proposed algorithm, compared with standard measuring tools and simulations.
