Gamelan is one of the traditional musical instruments in Indonesia. Gamelan is also one of the cultures that must be preserved. To preserve gamelan, one way is by combining gamelan with technology that is currently developing. The technology that is currently trending is virtual reality. Virtual reality is often used for games in three-dimensional form. Gamelan can be something interesting in VR. In VR interactions, there are two interactions that are often used, namely controllers and hand tracking. Hand gestures are usually tracked using the built-in camera of the VR. Hand tracking can be used in VR applications to control the virtual object just like a controllers. This study aims to compare the use of controllers and hand tracking that involve interactions, namely collision, pressing, grabbing, and release. Thirty two Atma Jaya Yogyakarta University students who had tried virtual reality and played gamelan or had seen gamelan performances explore the differences between VR hand tracking and VR controllers in VR gamelan sharon. SUS (System Usability Scale) and USEQ (Use Questionnaire) were used to measure user usability and satisfaction. The result of the SUS score showed that users were more interested in using controllers than hand tracking. But the USEQ results showed that there were no difference in usefulness, ease of use, and satisfication. Based on the results of the interaction, using controllers looked more comfortable, but using hand tracking, playing gamelan looked more realistic.

In creating a simulated world, it is very necessary that the environment, objects, and experiences be similar to the original conditions in the real world. Simulation can be carried out using virtual reality technology, in which environments and objects can be created as desired. The creation of these three-dimensional objects can be achieved by taking into account the 10 principles of photorealism to get realistic objects like those in the real world. In this research, objects from the Kenong gamelan will be created using the principles or characteristics of photorealism. In this study, an assessment of three-dimensional objects was made by distributing questionnaires in which the selected respondents gave a value of 1–5 for each photorealism characteristic of each object. From the results of the assessment carried out, it was found that the 3D objects that were previously made received a value above the average, which means that they meet the characteristics of photorealism. Data was also obtained indicating that realistic 3D objects are required in a simulation in order for the simulation to be felt more strongly or for the user to feel the feeling as closely as possible when playing gamelan. From the results that have been obtained, it is recommended to follow the principle of photorealism when creating 3D objects for simulation needs.

The increase in information technology in today's era makes the availability of Augmented Reality or Virtual Reality enabled devices, which can become a gateway to exploring various applications, increase. For the example is the virtual reality application of Gamelan Slenthem, which is currently being developed with the aim of making Indonesian cultural musical instruments. Even though what is developed is not an application or an ordinary website, the user interface is still one of the most important stages in the development of an augmented reality or virtual reality application. Every information technology has an interface that can be a link between the user and the technology itself. The interface is influenced by needs, and information technology has a design that makes it easy for users to operate information technology and can make users feel comfortable using the application or technology. In this study, we will use heuristic evaluation to evaluate the application of the virtual reality gamelan metaverse game. Heuristic evaluation itself is a method of evaluating user interfaces and usability that can be used to determine the extent to which a system is used by users to achieve certain goals effectively, efficiently, and satisfactorily. This research focuses on evaluating the use of heuristics in user interface design based on usability aspects through observation and interviews with users.
