Abstract

This study aims to design a microcontroller-based tripod movement controller. Lots of people carry a camera when they are traveling or traveling. They brought cameras to make documentation while traveling for collection. While traveling, sometimes many travelers who travel alone or solo travelers have difficulty when they want to take pictures of themselves. Usually we will ask for help from other people who are around the place to take pictures so that the photos we take are good. If you are in a crowded place, of course this will not be a problem. However, if you are really alone, of course it will be difficult to do that. To overcome this, usually people use a tripod so he can take pictures of himself. The author tries to provide a solution to the problems that have been detailed previously by creating a system that can help photographers take pictures more easily. The system that will be made in the design of this microcontroller-based tripod movement controller uses bluetooth as a source of communication between the two Bluetooth pieces in building the system. wireless and to adjust the movement of the tripod in the specified direction using a servo motor, remote control as a remote controller, By connecting Arduino nano with bluetooth and a servo motor, the tripod can be moved remotely via the remote control. The purpose of this research is to develop a tool as an alternative that makes it easier for photographers to take pictures with a steady position. Keywords: Tripod, Bluetooth, Motor Servo, Remote Control, Arduino Nano

Abstract

Tryout in the scope of education in Indonesia is a trial that is usually carried out before facing the actual exam, or among students refers to a trial before facing a computer-based national exam (UNBK). The problem that has been identified is the implementation of the exam is still applying a traditional system that uses exam paper and fills in the answers themselves using pencils and pens. Therefore, this research focuses on designing a tryout exam application applying the linear congruent method held in schools, especially vocational high schools (SMK). This method is an algorithm used to generate random numbers. The function is to randomize questions, which can be defined as a mechanism for randomizing questions to create new questions that are different from the last. Hopefully, this application can help schools in terms of making, multiplying and distributing questions being tested. In addition, the results can be printed directly using a computer

Abstract

Cryptography is a science based on mathematical techniques related to security and information such as confidentiality, data integrity and entity authentication. In other words, it means to conduct the process of encoding libraries that act as ciphers, and converting the original text into illegal it. The implementation of encryption process requires a public and a secret key. One of the cryptography techniques applied in the research is the Algorithm of Vertical Bit Rotation (VBR). The VBR is a technique that implements an asymmetric key, which it has a same value in term of data encryption and decryption. The technique is also applied in the shape of an application designed in this research, then have ability to run encryption and decryption process in the format of text file, that providing data security to avoid eavesdropping and illegal access from irresponsible parties. The result done by using VBR is it may run well so have ability to restore the condition of the data in plaintext, then in addition information, encrypted data cannot be returned to its pure form without using a valid key

Abstract

One feature of a smartphone device that is still often used is the exchange of messages such as text chat. This exchange of information generally knows no distance, can be far or close. This requires security of the confidentiality of information sent from the source to the target. One way to get the security of communication is by applying cryptographic techniques so that the message sent to the target can be secured. The cryptographic technique used in this study is Vigenere Cipher. The Vigenere Cipher algorithm is used to encode text conversations so that messages sent via the internet can be maintained as well as with confidentiality. The purpose of this study is to build a text conversation cryptographic application that can run on Android-based smartphone devices. The technique can encrypt text conversations into secret messages which then the results (messages) are sent using a message sending application such as SMS (Short Message Service), Whatsapp and Line. Then when the message arrives at the destination, the description is done automatically so that the original message can be read.

Abstract

Art exhibitions as a means of displaying creative works require innovation in the interaction between visitors to artworks. Currently, the use of augmented reality (AR) in art exhibitions is increasingly relevant and attracts attention as an interactive medium. However, challenges in its implementation still exist, including the lack of visitor engagement and limited physical space. The proposed solution is to use the marker-based tracking method in AR, which allows the integration of artworks with the environment through visual markers. This method allows visitors to interact directly with artworks through their mobile devices. In this context, the marker-based tracking method uses physical and visual markers, such as images or certain objects, to trigger AR elements. Visitors can access additional content, such as information about the artwork, multimedia interactions, or dynamic visualizations, by pointing their devices at the specified markers. This creates a new dimension in art, allowing visitors to interact directly with artworks through additional digital layers. The result is increased visitor interaction and participation in art exhibitions, resulting in a more immersive and dynamic experience. This system is expected to broaden the appreciation of art, encourage discussion, and enrich the visitor experience. The main goal is to enrich the visitor experience in understanding, appreciating, and enjoying artworks through interactive and innovative technology. Thus, the use of AR in art exhibitions with the marker-based tracking method not only creates a creative and immersive experience, but also opens up new potential in connecting art and technology to create a richer and more memorable experience. The results achieved from this study are in the form of providing a deeper experience to visitors in a painting art exhibition.
