Abstract

Swimming is an activity that popular. However without realized, the water of swimming pools have a not good enough quality, so that it becomes a medium for the transmission of various diseases in water. Monitoring quality of swimming pool water is a sanitation effort, namely by providing liquid chlorine to reduce organic substances and as disinfection against microorganisms. With this problem, the authors conducted research on telemonitoring system of turbidity and ph of water for draining and providing automatic chlorine in smartphone-based swimming pools. The system applied to a miniature swimming pool consisting of four sensors, namely pH sensor, turbidity sensor, ultrasonic sensor, waterflow sensor, the four sensors will send data to ESP32 to be processed according to the system. After ESP32 has finished processing it is then sent to firebase and an application on a smartphone to make water monitoring and control easier. The test results can be concluded that system designed using ESP32 as a microcontroller will process data from the pH sensor, turbidity sensor, waterflow sensor and ultrasonic sensor. Then the results of pH data have highest pH value of 7.9 and lowest of 6.9. Furthermore, results of the turbidity sensor data have a value of 0 NTU with highest ADC of 3827. The drain is automatically divided into 2, namely monitoring and controlling. Furthermore, the quality of WiFi network tested using Wireshark when carrying out data transmission process in terms of delay has average value of 0.188389435, packet loss is 1.178 and throughput is 7428 Kb/s.

Abstract

In this technology age, people's need for communication systems is growing. In various places and conditions, communication must be maintained to meet various needs. One of the solutions required in these circumstances is an optical fiber communication system. Fiber optic cable is a light-based data transmission technique. The advantages of optical transmission include the fact that the light spectrum does not spread like radio frequencies, making it impossible to intercept, the fact that it propagates at a very high speed, allowing it to go very large distances, and the ease with which it may be installed. To tackle this problem, we proposed to innovate by realizing and developing a two-way voice and text communication system using fiber optic cable media. The voice and text communication system created and deployed in this study is based on an Android application. This communication system does not require a server and internet network. Only Android smartphones, access points, fiber media converters, and fiber optic cables are required. The greatest throughput value measured by the system is 2708 bytes/second, while the lowest is 1020 bytes/second. The longest delay is 2.314 seconds, while the shortest is 1.99 seconds. In terms of packet loss, the value is 0%.

Abstract

IP Phone is a Voice over Internet Protocol (VoIP) device that can transmit voice using IP. From communication between IP Phones there are waveforms of input and output information signals, the response of voice amplitude to changes in voice frequency and delay value from time shift at the beginning of the wave period of the input and output information signal using the Transmission Test Set and Oscilloscope measuring instruments to determine the character of the sound quality in communication between IP Phones according to the parameter test results. The system test results are that the waveform of the input and output information signal at the sound frequency has a sine wave shape. However, the output waveform of IP Phone A with a frequency of 300Hz to 1100Hz and IP Phone B with a frequency of 300Hz to 1300Hz is distorted, then from the results of the Peak to Peak wave is known to have a voltage gain, that is, the greater the frequency value at the input, the smaller the value of the resulting voltage gain.

Abstract

Duck eggs are an animal food that can be consumed. In community life, generally there are two ways of salting, namely the first with water, salt, and bricks. The process of mixing water and salt still uses the manual method, namely by hand. Salt is a major factor in the salting process of eggs which functions as a preservative to prevent spoilage of eggs, thereby increasing their shelf life. In order to become salted eggs in general, that is by preservation. The method used is experimental, the purpose of experimental research is to create or develop an existing research.The test results on this tool are to produce specification data or to get certainty whether a tool is functioning properly or not. So that if there is damage to the tool or equipment it cannot run properly, it can be analyzed precisely and easily, and we can conclude that the difference in the results obtained from one day to the next

Abstract

Generally, height and weight measurements are carried out separately as well as to determine the Body Mass Index must be calculated manually using specific formulas that not everyone understands, so it is difficult to know whether the body has reached a normal number or not. This study will provide suggested solutions to support the body to be healthy in measuring devices and android applications, for height measurement using ultrasonic sensors, weight using loadcell sensors and NodeMCU ESP8266 as data processors. The results of measuring height and weight appear on an LCD, the results of Body Mass Index (BMI) and the recommended solutions to meet standard body numbers in calculating BMI appear on the android application. Based on the results of the tests carried out, it is known that designing a measuring instrument with NodeMCU ESP8266 based on Android has been successfully carried out. The measuring instrument by implementing the Ultrasonic Sensor HC-SR04 as a height measurement can perform a success percentage of 96.95% and Loadcell Sensor as a weight measurement can perform the percentage of success is 98.97%, while in measuring Body Mass Index (BMI) can do a success percentage of 90.84%, the measuring instrument can also emit sound in the form of body condition in accordance with the measurement results obtained by the microcontroller with a success percentage of the sound output of 100% but has an average percentage of voice output delay variations of 2.1 seconds.

Abstract

A kiosk / traditional minimarket is a small shop that generally sells goods like a modern minimarket. During this pandemic, it is recommended to pay for an item without contact (online) to break the chain of the Covid-19 virus. Therefore, an Android-based smartphone is very useful for making payments for an item online. Most people desire to have an item they want even though the price offered is sometimes quite expensive. However, some buyers want to get the goods as soon as possible and for payment to wait for a certain period according to their ability. This is detrimental to the kiosk owners because they do not get income from selling their goods. This reminder makes it easier for sellers to collect bills automatically without waiting for buyers to shop again at the same kiosk. Besides that, there is a limit for each buyer, which is useful for kiosk owners, so they do not lose money. This research needs to have a communication system that can make it easier for kiosk owners to collect bills from their customers without waiting for the customer to come again to shop at the same kiosk. In other words, the kiosk owner has certainty from the customer according to the agreed payment due date.

Abstract

The pandemic period caused by the coronavirus disease causes restrictions on the number of users in a room to minimize the spread, for example, libraries. The library is a room area that can cause virus transmission when crowds of visitors. A system is needed to provide information regarding the number of library visitors. Utilizing a network (wifi transmitter) available in the library can provide information on the number of visitors based on the number of network users in a room. Utilization of the network (wifi transmitter) can be in the form of a positioning system by utilizing the wifi signal beam received by the user in RSSI (Received Signal Strength Indicator). To calculate the estimated user position, a trilateration method is used based on the placement of three wifi transmitters. The library visitor positioning system consists of users as wifi transmitter users and admins. At the X-coordinate, the measuring point with a low deviation of the measurement value is indicated by points C and E with a value of 0.1. The large deviation of the measurement value is indicated by the P point of 4.5. At the Y coordinate, point O has a low deviation value of 1.25, and the largest deviation value is at point M of 5.6. The accuracy of the X coordinate shows a value of 97.647% and at the Y coordinate of 96.57%. Both coordinates have good accuracy for the points used as position measurements.

Abstract

This paper summarizes and gives examples of the using of IoT in Industry 4.0, especially in Oil and Gas Refineries. Industry 4.0 and Industrial Internet of Things (IIoT) technologies are driving digitalization driven by software and data solutions in many areas, particularly in industrial automation and manufacturing systems. Global refineries are currently all heavily instrumented, and process regulated in real-time to the millisecond. To meet the ever-increasing needs of operational demands, SCADA, Distributed Control Systems and Programmable Logic Controllers (DCS & PLCs) have grown significantly. On the other hand, certain assets and operations in a refinery are still not being monitored or evaluated in real-time. If an error occurs that causes production to be hampered, the company must bear large losses even though production stops in just a matter of minutes. This is one of the reasons why the oil and gas sector is starting to implement the Internet of Things (IoT). The overall aim of this paper is to give and summarize several papers to provide solutions for a simple process monitoring system that would enable process operators to identify any sources of abnormality quickly and easily in the process. A system is being made so that it can be accessed and transmit data remotely via a computer network and will display conditions in real-time without being limited by distance, space, and time. This will allow all previously disconnected assets and processes to be linked and monitored in real-time in a simpler, cost-effective, and easy-to-implement manner.

Abstract

This paper introduces a millimetre-wave antenna design for 5G application using an alternative substrate called Kevlar-Alumina Composite. Kevlar-Alumina Composite had been researched and measured comprehensively by Indonesian Institute of Science (LIPI) Bandung showing dielectric value of 9.2. The application of the antenna geometry is based on Vivaldi Coplanar antenna with L shaped feeding on the ground plane. Vivaldi Antenna is chosen as it has a relatively small size with various structures. An antenna of 3.75 GHz for 5G application using Kevlar-Alumina Composite is proposed. The simulated results of single-element 5G antenna have return loss value of -21.949 dB, 1.173 VSWR, directive radiation pattern at E-Plane and H-plane, and surface current. The use of the Kevlar-Alumina Composite performed good results.
