Abstract

The most important stage in making a mobile application is designing an attractive display design. The Only One Cloth store still uses social media to sell products, besides that the factors that are still limited to the Only One Cloth Store are the lack of payment system organization and descriptions, therefore an application display that is needed by the store and potential users is made. The user interface (UI) is a form of graphical display that relates to potential users. User Interface works to connect users with the operating system on the computer so that prospective users can use it easily. Making the application display uses the iterative Design Thinking method where we try to understand the user, challenge assumptions, and redefine the problem in an effort to find alternative strategies and solutions. The Design Thinking method consists of five stages, namely Emphatize, Define, Ideate, Prototype, Test. At the Test stage, a test will be carried out on the value given to the task from the application display that has been made. The values that have been collected will be tested using the Single Ease Question (SEQ) method and get a value of 6.4 from the total tasks that have been assessed, if one task has a value of 5.5 then it must be iterated again. Judging from the SEQ results from the appearance of the application that is made feasible 6.4 then the appearance of the application is already easy to use by potential users

Abstract

Indonesia, namely, an archipelagic country that has a variety of cultures and so many tribes. But most of us don't realize that. For this reason, we need to cultivate a sense of nationalism and love for the homeland from an early age, especially young people in Indonesia. Most people in the school environment only use books to study it and only make students bored quickly. There are many ways that teachers or parents must do by using a mobile phone. The development of the mobile phone, media, which is one part of a medium for delivering information, which is currently an alternative new method that can be used as a means of delivering information in an attractive, easily accessible, and clear form. It can also help all people to know the various cultures in Indonesia. Therefore, an android-based application was made, namely the Application of the Linear Congruential Generator Algorithm in the Introduction to Culture in Indonesia, in order to help and make it easier to find out about culture in Indonesia. The Linear Congruential Generator (LCG) method is a randomization algorithm used to generate a random number (Random Number). From the results of the research that has been carried out, it shows that the Linear Congruential Generator (LCG) method is very effectively applied in randomizing letters and questions.

Abstract

Fire disasters often occur due to various factors, one of which is public negligence and lack of anticipation to prevent fires from occurring. In most cases, the fire is often known when it has grown. Based on these problems, we need a system that can detect fires as quickly as possible from the appearance of smoke to prevent the emergence of a fire that is getting bigger. In this study, the author will create a system in the form of a fire smoke detector using an Arduino Uno microcontroller with the fuzzy mamdan method. The author wants to compare the fuzzy mamdani method and the Arduino device to get the most accurate results possible. Fuzzy reasoning was chosen because this method is able to calculate data that is vague to not vague, commonly called a vague analogy, namely the value used is between 0 and 1. In this system there is an MQ-2 sensor module to detect smoke and an LM35 temperature sensor connected to the Arduino Uno microcontroller. as a center for controlling the work of other devices and a data processing center on the system. And the program is made on Arduino IDE. With an LCD output to display information about the presence of smoke and an output in the form of a buzzer to give a warning sound. In this study, the results showed that the Fire Smoke Detection System Using an Arduino Microcontroller with the Fuzzy Mamdani Method could run well and produce state outputs that were in accordance with the fuzzy calculations in Matlab.

Abstract

Covid-19 is a pandemic that has hit the world, including Indonesia. This pandemic can be transmitted from direct human-to-human contact. With social restrictions and also maintaining health protocols, it is felt that they can prevent the transmission of Covid-19. Areas of the face such as the mouth and nose are considered to be the fastest means of spreading. So it is necessary to use masks to reduce the spread of this pandemic. In addition, to prevent transmission a person can find out Covid-19, one of them is through body temperature. Therefore, the use of technology is considered very important in order to minimize and detect the spread of Covid-19. By using this method, it is expected to detect the use of masks and detect body temperature, in order to minimize the transmission of Covid-19 in the room.
