Abstract

In order to reduce the computational volume, we employ selective encryption approaches in conjunction with a chaos-based picture encryption algorithm in this research. Two chaos maps are used, namely Arnold Cat Map and Logistic Map. Before encryption, the image is scrambled with Arnold Cat Map, then selective encryption techniques are applied by selecting only four MSB bits from each pixel to be XORed with the keystream generated from the Logistic Map. Experimental results show that the use of both chaos functions can produce confusion and diffusion effects, and the use of selective encryption techniques only processes 50% of the entire image data. The encrypted image shows a relatively uniformly distributed histogram, making it difficult for attackers to perform statistical analysis to find the key or plain image. Chaos sensitivity shows that this algorithm is safe from exhaustive-key search attacks. This method is sensitive to modest changes in the key, making it safe from exhaustive-key search assaults, according to experiments conducted by gently altering the initial value of chaos. This technique is immune to brute-force attacks because of its sufficiently huge key space.

Abstract

Augmented Reality (AR) combines computer-generated graphic objects with real objects, so that virtual collaboration occurs between the two types of objects. The main purpose of AR is the use of computers as devices to facilitate a job done by humans. Based on its characteristics, AR has great potential to be used as a computer game platform. The research reported in this paper raises the issue of utilizing AR as a computer game platform. The research was conducted in the form of developing a marble maze computer game using AR with an emphasis on the interaction aspect. The lighting conditions of the playing environment have a crucial influence. To get a consistent appearance, adequate lighting is needed. However, AR-based games are one of the interesting games to play. The game must be played in well-lit environments, with a flash light, or with a high-sensitivity camera in order to get around this. Nonetheless, the majority of volunteers acknowledged that they were open to playing games that used augmented reality.

Abstract

It is very possible for a musician who works in the modern technology era to be familiar with digital sounds or tones. They even use technology in music in the modern era. Currently, there are many models of digital music devices, both physical and non-physical. One of them is a digital effect for bass and guitar. The size of the device ranges from large to simple. The obstacle faced is that musicians, especially those who are still new to utilizing technology, often have difficulty controlling it. This is due to the simple design of the device, which makes it more difficult to use on stage because of the many preset tones and controls available. Because digital effects require large storage capacity, their function is similar to the processor in the CPU. Technology devices such as the Digital Audio Workstation (DAW) feature allow users to produce their own music without having to rent a recording studio. On this occasion, this article will discuss the design of a MIDI manager model as a tool in carrying out the audio processing process. In the design, we use Arduino Leonardo technology with an ATmel Mega 32u4 processor as the control engine. The result is a device that can control features in DAW, which makes it easier for musicians to manage audio both during the recording process and on stage.

Abstract

The cruciality of a logo for city branding interests is comparable to the need for seriousness in the design process. Several studies have stated that the main problems with city brand logo design methods are: the ineffective involvement of local communities, and the low understanding that city branding is more than just designing a logo. This study aims to formulate a city brand logo design method that (1) involves local communities and (2) is connected to the overall city branding process. To that end, a study was conducted on city branding theory, brand personality, city brand visual identity, including case studies of city brand logo design in Indonesia. The city brand logo design method formulated here is divided into the idea search stage (research, brand personality exploration, city branding concept) and the visualization stage (testing preferences for logo types and their visual elements). At each stage, community involvement is carried out through questionnaires while the design team plays a role in designing alternatives for the community. This proposed method is able to facilitate collaboration between designers and the community in designing the city's visual identity, as well as providing branding output that is (not only a logo and slogan, but) integrated with the brand's personality, core ideas, and all strategies that play a major role in implementing city branding as a whole.

Abstract

The rapid development of social commerce has changed the way consumers shop and interact with brands. However, the success of social commerce platforms cannot be separated from a deep understanding of the factors that influence consumer satisfaction and purchase intentions. This study aims to analyze the success of social commerce using the Expectation Confirmation Model (ECM) method. ECM is a model that explains that consumer satisfaction is influenced by the confirmation of their expectations of a product or service. This study identifies the main problems in social commerce, namely consumer uncertainty about product quality, transaction security, and shopping experiences that meet expectations. The research method used is a quantitative approach with a survey of consumers who have shopped through social commerce platforms. Data were analyzed using descriptive and inferential statistical techniques to test the research hypothesis. The results of the study showed that confirmation of consumer expectations about product quality, transaction security, and ease of use of the social commerce platform had a positive effect on their satisfaction. In addition, consumer satisfaction also influenced their repurchase intentions on the platform. Based on these findings, this study offers solutions for social commerce managers to increase the success of their platforms. These solutions include providing clear and accurate product information, ensuring transaction security, and improving an easy and enjoyable shopping experience.
