Abstract

This research aims to obtain optimal drilling machining parameters in response to tool life, surface roughness and response to the influence of electric current. Tool life is a derivative of the wear value obtained. The Taguchi method is often used to determine optimal quality in single response manufacturing processes. However, when there is more than one response, researchers often use the Gray Relational Analysis (GRA) method. This research was carried out on the response of tool life, surface roughness and the effect of electric current on Magneisum AZ31B type material using four factors and mix levels. The chisel diameters used are 8 mm and 10 mm. The spindle speed is set at 890 rpm, 1270 rpm, 1700 rpm and 2000 rpm, feeding uses values of 0.1 mm and 0.3 mm, while the point angles used are 118° and 135°. The optimal results obtained in this research were using a tool diameter of 8 mm, spindle speed of 890 rpm, feeding of 0.1 mm, and point angle of 118°. Keywords: Drilling, Taguchi Method, Gray Relational Analysis, Tool Wear, Surface Roughness, Electric Current.

Abstract

Fuse Cut Out (FCO) is a separation device in medium voltage networks, FCO removal is done by separating the top contact with the fuse carrier. How to remove the fuse carrier in general still uses a manual method with special equipment, namely a 20KV telescopic stick. The use of telescopic sticks is very time consuming and prone to leakage of insulation which affects work safety. In this study, the release of the fuse carrier was carried out with a remote control as a command to release and enter the fuse carrier.  Testing of this tool is carried out at a voltage of 223 Volts AC. The remote control design is able to provide a command signal with a maximum distance of 21 m in real time conditions. The mechanical construction is adapted to the standard clearance distance in the medium voltage network and the results of mechanical manufacturing of the upper contact with the fuse carrier release distance of 207 mm and the upper contact with the pneumatic actuator of 200 m, the compressed air source uses 5bar. The average success was 88.8% Phase R, 77.7% Phase S, 77.7% Phase T. The construction of the fuse carrier drive tool in this study is used in the release of FCO so that release and entry require faster time and optimise work safety.

Abstract

Motorbike theft is increasing, causing concern and losses for vehicle owners. Preventing motorbike theft can be done by creating a prototype of an innovative motorbike safety device based on Arduino Uno which integrates global positioning system (GPS) technology, notifications and distance control via short message service (SMS). This tool uses Arduino Uno as the main control brain, with a NEO-6M GPS module to obtain accurate location information. The SIM800L V2 GSM cellular communications module is integrated to transmit location data and receive commands via SMS. Passive infrared (PIR) sensors for movement detection are also implemented to detect and respond to theft attempts. The system can provide notifications to motorbike owners via SMS messages when suspicious events occur, such as unwanted movements or attempted theft. Users can control certain functions such as turning off the vehicle using a relay as an electrical breaker in the vehicle. Tests are carried out to ask about location, notification response speed and general security of the tool. Testing the tool was carried out in several steps, firstly testing the SIM 800L function to see the cellphone's access speed in receiving signals, secondly testing the GPS NEO-6M to see the speed of accessing map sending, thirdly testing when the motorbike was moved to a certain point. This will see how fast the tool is designed to send signals via SMS. Based on tests carried out, this tool provides a fast response in the range of 8 to 80 seconds. Test results show that this tool can provide an effective handheld and innovative solution to improve motorbike safety through the advantage of simple but efficient technological integration.

Abstract

Not all situations allow for direct observation of the object being observed. This is due to several factors, such as distances that are too far or terrains that are too dangerous to reach, as well as weather and temperature conditions that are not supportive. Therefore, observation or measurement cannot always be done directly and continuously in these difficult-to-reach locations. To overcome these constraints, telemetry is used for long-distance measurement. However, telemetry requires an adequate transmission range. One efficient method for long-distance transmission is using Long Range (LoRa) technology, which has deficient power consumption. LoRa repeaters are required to forward data from the Node to the Gateway to extend the transmission range. In this study, a LoRa repeater was developed for LoRa communication using the LoRa TTGO ESP32 module. The results of this repeater development demonstrate its ability to forward sensor data from the node to the gateway with a range of up to 2.8 km and a data transmission delay of 0.7 seconds.

Abstract

There are many motor vehicle accidents on the road, one of the causes being tire blowouts. These accidents occur because drivers continue to drive their vehicles even though the tire pressure and temperature exceed the specified threshold. To address this issue, there is a need for a tire pressure and temperature monitoring system that can be continuously monitored by the driver. If there is a malfunction in the monitoring device on the vehicle dashboard, the driver can be alerted by others who also monitor tire pressure and temperature information remotely. In this study, we developed a tire pressure and temperature monitoring system for vehicles that can be accessed remotely using Internet of Things (IoT) technology. Additionally, we utilized Software Defined Radio (SDR) technology for pressure and temperature data reading. This system successfully monitors tire pressure and temperature changes remotely via computer and smartphone. Based on the test results, the best standard deviation value for tire pressure is 3.54, while the best standard deviation value for tire temperature is 1.72

Abstract

Voltage stability is one of the main concerns in the electric power system. One of them is related to the voltage sagging problem. The cause of voltage stability problems in the electric power system is the motor starting event. The current motor starting method that is often used is to use a VFD soft starter. There is another method to mitigate voltage sagging problems during motor starting events using the liquid starter technique which is still rarely used. The simulation results obtained show that by using a liquid starter there is a slight decrease in the voltage profile, low starting current, smooth start, little impact on the grid. This was proven in the application of a liquid starter using etap software and Matlab plotting. The smallest value of the voltage profile was 90.35% and the starting current was 6 times lower than the direct online method. From this application, the liquid starter method has proven to be much more effective in overcoming high voltage and current sags during motor starting events.

Abstract

Based on PLN standards regulated in Minister of Energy and Mineral Resources Regulation No. 20 of 2020, changes in voltage on the network must be maintained within the voltage variation range of ±5% (Normal Voltage). Voltage is the change in voltage variations in a short time. Where the voltage change exceeds or below the standard voltage variation range, namely ±5% of the normal voltage. Based on IEEE Standard 1159-1995, the sag voltage is in the range of 10% -90% of the nominal voltage which lasts for 0.5 cycles. The voltage wave is in the range of 120% of the nominal voltage. Changes in voltage variations are caused by many factors such as large motor starting currents, uncontrolled load changes and short circuit current disturbances in the electric power system. The importance of maintaining voltage is a necessity because it is related to the reliability of an electric power system. For this reason, this research proposes "Application of the Fast Fourier Transform Method to Monitor Voltage Fluctuations" as a solution to power quality problems. To make it easier to process voltage (sinusoidal), the Fast Fourier Transform (FFT) method is needed. The FFT method algorithm is needed to convert the time domain into the frequency domain, so that it can simplify the monitoring system process. This research was implemented the FFT method for monitoring voltage fluctuations in no-load and load conditions. From the results, it can be concluded that inductive loads can affect voltage quality. This was proven when carrying out tests under load, from the results of the analysis there was a decrease in voltage (voltage SAG) of 10% (Vrms = 209.5 V; time duration 0.1436 s) and an increase in voltage (voltage swell) of 20.6% ( Vrms = 278.75 V; time duration 0.228 – 0.428 s).
