Abstract

Pada masa industri 4.0, data menjadi salah satu komponen yang wajib dilindungi. Block cipher merupakan salah satu algoritma yang digunakan untuk mengamankan data. Penelitian ini bertujuan untuk mengimplementasikan algoritma block cipher four (BCF) pada mikrokontroler. Parameter yang menjadi tolak ukur antara lain besaran flash dan RAM mikrokontroler yang terpakai, serta kecepatan eksekusi proses komputasi algoritma BCF. Mikrokontroler akan menjalankan algoritma BCF dengan urutan komputasi key-schedule, enkripsi, dan dekripsi. Setiap kali memulai proses komputasi, maka pin trigger pada mikrokontroler akan mengirimkan sinyal rising ke osiloskop dan pada saat selesai melakukan komputasi maka pin trigger mikrokontroler akan mengirimkan sinyal falling ke osiloskop. Hasil penelitian menunjukkan algoritma BCF dapat diimplementasikan pada mikrokontroler STM32F103C8T6. Flash dan RAM yang digunakan mencapai 22,02 Kb dan 5,12 Kb. Algoritma BCF yang diimplementasikan pada mikrokontroler STM32F103C8T6 mampu berjalan sampai dengan 704 kali lebih cepat jika dibandingkan dengan prosesor NIOS II, 11 kali lebih cepat dibandingkan dengan AES-Engine, dan lebih lambat 4 kali jika dibandingkan dengan BCF-Engine.

Abstract

Changes in temperature can affect the accuracy of the estimated SoC value based on voltage. In this study, fuzzy logic was implemented to correct the SoC estimation error caused by the influence of temperature. The system acquired data through sensors and then processed it using the Arduino microcontroller. Parameters in the form of voltage, temperature, and current were processed by Arduino with a fuzzy logic program which was uploaded into it and produced the output of the estimated SoC value. From the observations, it was found that the estimated SoC value from this method had better accuracy with a smaller error than the SoC estimation based on voltage alone. Using the RMSE method, the errors calculated in this method in the process of charging and discharging without running were 2.26 and 7.74, while the SoC estimation error based on voltage alone reached 4.88 and 12.8. In the discharging process with a running car, the SoC estimation results using fuzzy logic also showed accurate results. There was only 1% of SoC value increasing pattern during the discharging process, which the value trend should continue to decrease and should not be an increase. In addition, compared to the previous method applied to the same research object, namely the chemical equilibrium constant method, this method also showed more accurate results.

Abstract

Brushless DC motors (BLDC) are one of the most widely used types of DC motors, both in the industrial and automotive fields. BLDC motor was chosen because it has many advantages over other types of electric motors. However, in its application in the market, most of the control systems used in BLDC motors still use conventional controls. This conventional method is easy and simple to apply but has many weaknesses, one example is that if the system state changes, then the parameters of the PID must also be changed so that static and dynamic performance will decrease, causing slow response and frequent oscillations. In this study, the design and simulation of a speed control system for BLDC motors using the Fuzzy-PID method were carried out. The research method is performed through simulation with Matlab / Simulink. The simulation is carried out by providing a speed setpoint input of 650 rpm and used 2 methods, namely Fuzzy-PID Logic and Pi conventional method which was carried out for 1 second. The test results show that the Fuzzy-PID control can provide better and more stable performance than the conventional PI control. The use of Fuzzy-PID control can reduce speed fluctuation and torque stability so that the BLDC motor can operate more efficiently and reliably.

Abstract

Facilities and services are needed reliable for the comfort of airplane passengers. One of the important facilities in airport services is the Public Address System (PAS). PAS is a notification system using sound electronically distributed with amplifiers, loudspeakers, and microphones. PAS functions to provide information from the airport and airlines to be conveyed widely to airplane passengers. In order to reduce the possibility of misinformation or delivery of unclear information from the operator, the author aims to create Semi Automatic Announcement System (AAS) website where someone no longer needs to speak directly but only needs to enter a notification sentence, then the system from the website will speak or also can be referred to as text to speech. The system is expected to reduce misinformation so that information can be clearly understood by passengers.

Abstract

This research designs and implements an information system to manage web-based Semester Learning Plan using cloud computing technology, software, computers, and repositories as well as a serverless architecture. So far, the preparation of Semester Learning Plan in Department of Electrical Engineering UIN Sunan Gunung Djati Bandung is still done manually using a template in Microsoft Excel format. This method is considered ineffective because filling in takes a long time and the output is sometimes not uniform, both between lecturers and between courses. Based on this background, the author proposed the idea of creating a web-based Semester Learning Plan management information system. The method used to develop this system is the waterfall method which consists of five stages, namely requirements analysis, system and software design, implementation, testing, operation and maintenance. This information system using cloud computing technology and serverless architecture. The result of this research is a web-based Semester Learning Plan management information system. Through this system, lecturers no longer type manually into doc or xls format, but lecturers can directly input into the system or the web. The output is that the Semester Learning Plan can be downloaded and is in accordance with the applicable format and is in pdf format. The existence of this system can increase the effectiveness of lecturers in managing Semester Learning Plan.

Abstract

Chicken or duck farming is one of the businesses that has good prospects. Conventional hatching of chicken or duck eggs has its own risks with a hatching success percentage of <81%. The hen or duck also needs time for further breeding because they have to incubate the eggs first. Egg incubators on the market usually use on-off controls to regulate incandescent lights which can cause the temperature to fluctuate. Air humidity settings are also manually set by the user. Researchers have conducted studies related to temperature and humidity settings. This article reviews articles from the Scopus database related to control systems in egg incubator with research questions: controlled parameters, sensors used, control theory, methods, and research results that have been carried out. The result of this article can provide an overview of the research development related to egg incubator control systems.
