Abstract

Abstract— In maintaining the quality of aviation fuel, before being marketed, the aviation fuel must pass through the filtering stage using a filter. The use of filters must be monitored for efficiency by using a PDG (pressure different gauge) instrument. PDG is a measuring device that is equipped with a switch and will be a disconnect when the PDG needle shows a number above 15 psi. However, filter monitoring is only done by looking at the PDG installed on each filter and the switches on the PDG have not been used at all. From this problem, the author conducted research out by designing and building a tool that can monitor switches on the PDG and provide SMS notifications. In its design, the device uses Arduino Uno as a microcontroller with a 12VDC power supply. This device is equipped with GSM SIM900A which functions to send SMS. Based on research, the highest current consumption is 0.18 A and the smallest is 0.11 A. The average time for sending an SMS is 7 seconds. Based on testing the tool can work as expected. With the design and construction of this device, it is expected to help PT. Pertamina DPPU Ngurah Rai to monitoring the performance of filters in realtime so that the replacement of filter elements can be done in a timely manner and maintain the marketed aviation has good quality.

Abstract

The Internet has become a necessity for modern society in carrying out its various activities today .The rapid increase in Internet users from year to year shows that people's need for the Internet is increasing .In Indonesia, Internet user growth is predicted to increase by 10.2 percent annually from 2018 to 2023.However, the growth in the number of customers is often not followed by the ability of Internet providers to improve maintenance facilities to maintain the quality of service to their customers .One of the causes is the limitations of the device which is often an obstacle for technicians to do maintenance as soon as possible. This research aims to be able to design and build devices that can be applied as a means of measuring network quality more simply and economically so as to support the mobility of technicians to use and maintain their networks .The devices built on the study are based on the Raspberry Pi 3 Model B. Comparison of device performance measurement results such as battery life, ping, upload and download rate between devices built with laptop usage gives almost the same results. This built lifter has advantages on the side of smaller and lighter dimensions and a much more economical cost.

Abstract

User behavior prediction on TCP / IP networks is very possible because each data packet is passed through a router that can be analyzed and then classified into several behavior types from commonly performed activities by internet users. User-behavior predictions developed using artificial neural networks (ANN), which can show accurate results in predicting the bandwidth used by users in the next few days. Predicting results helps network administrators to provide a more accurate picture of user behavior patterns in the future, where the Personnel Service Application System (SAPK) which becomes the user behavior internet priority it's only utilized network resources at 26.8% of the total internet network resources available. The ANN that was developed also showed that 40.3% of network resources were used more by streaming video activities and 37% were used for streaming audio activities. With the prediction result, the network administrator rearranges the internet network resources distribution by applying a new prediction results pattern. This study conclusively shows that user behavior with streaming video activities is the largest bandwidth user and needs to get special attention on the internet network at the Regional X National Civil Service Agency Office.

Abstract

Between the stator and rotor there is a gap called the air gap (air gap). In BLDC motors, air gaps can affect motor speed and motor torque. The purpose of this study is to determine the effect of the air gap on the speed and torque produced by the BLDC 3 phase double stator axial flux motor. Tests are carried out at 4 mm and 5 mm air gap, when the motor is not overloaded and when the motor is loaded, at a source voltage of 12V - 15V. The results of testing on the motor are not burdened, ie when the source voltage is increased, the voltage, current, frequency, speed, motor power and torque increase. At a 5 mm water gap, the results of the voltage, frequency and speed have a greater value than the 4 mm water gap. While the results of the motor current, motor power and torque have a smaller value than the 4 mm air gap. The results of the motorized test are when the load and source voltage are increased, the motor voltage, frequency and speed increase. While the current, power and torque of the motor decreases. At the 4 mm water gap, the results of the voltage, frequency and speed of the motor have a greater value than the 5 mm water gap. While the current, power and torque of the motor have a smaller value than the 5 mm air gap.
