This visual identity redesign aims to produce a redesign of the visual identity design that depicts the character of the Freesound band, as well as providing more selling points for the Freesound band apart from the work of the Freesound band's songs. The problems that can be identified are that the visual identity of the Freesound band is not yet optimal, so it is not widely known by the audience and the visual identity of the Freesound band is less attractive, so it has less selling value when applied to supporting media. In solving this problem, the glass box method is used, where this method has several stages, namely starting from the Preparation Stage, Incubation, Illumination, then Verification. This method begins with preparing all the tools and requirements for designing the design, then preparing yourself to process various reference ideas that will be used to design the visual identity design. The results of the redesign of the visual identity design were expressed in the main media, namely the manual book. With the redesign of this visual identity design, it is hoped that it will become something that sells for the Freesound band apart from its songs, such as publishing merchandise or posters for the Freesound band.

In this context, this research explores how organizations can adapt their recruitment and selection practices to address the challenges of the VUCA era. This study presents an in-depth literature review of recruitment and selection strategies relevant to the VUCA era. We highlight a shift from an emphasis on technical skills toward assessing adaptability skills, situational leadership, and the ability to collaborate in multidisciplinary teams. In addition, this research considers the use of technology such as data analysis and artificial intelligence in the recruitment and selection process. We illustrate its usefulness in identifying candidates that have the potential to deal with uncertainty and ambiguity. The results show that organizations need to change their recruitment and selection paradigm to be more responsive to the VUCA era. They should focus on identifying candidates who not only have the necessary technical skills but also have strong adaptability, problem-solving and collaboration abilities. Technology can be a valuable tool in assisting this process. In conclusion, recruitment and selection strategies in the VUCA era must follow market development trends and prioritize attributes that are relevant to the challenges faced by the organization. In this way, organizations can build a workforce that is ready to face uncertainty and achieve long-term success.
