Arachnophobia or known as irrational fear of spiders, can be detrimental to one’s health and overall well-being. Common procedures, such as Cognitive Behavioral Therapy or medication, are often inefficient and take a lot of time to demonstrate results, thus the alternative way of dealing with arachnophobia is urgently needed. Such alternatives can be achieved by utilizing Virtual reality technology, hence the purpose of the following research is to address the matter by developing Virtual reality based application with the help of Multimedia development life cycle method. The MDLC method was chosen due its ability to create multimedia application, and the collected results of the experiment demonstrate that indeed MDLC can be used as a method to develop the arachnophobia therapy application that is both time efficient and works as test shows the decreasing time used for use application as well as two respondents that able to be detected for having arachnophobia. In conclusion the application developed using MDLC is indeed able to be an alternative way of arachnophobia therapy.

This study aims to produce and test the feasibility of an RPG (Role Playing Game) Math Story Problem created using the RPG Maker MZ software. The research method used is the Research and Development method using research stages (1) needs analysis, (2) design, (3) implementation, (4) validation, (5) revision and (6) product testing. The requirements analysis stage is used to analyze competency standards, hardware and software specifications. The design stage includes storyline design, display design, flowchart and character creation in the game. The implementation stage is the stage of realizing the design into an actual product. The validation stage is carried out to assess the feasibility of the game that has been designed and created which is then determined by the experts to get the criticism and suggestions needed for improvement so that the game becomes even better. The trial phase is carried out by direct application in children's learning. This test was conducted on respondents aged 4-7 years using a questionnaire. The data obtained were processed by descriptive analysis to determine the level of feasibility of the game. The results of data analysis showed that the feasibility level according to material experts was 96% which was included in the very feasible category and children as users was 83.75% which could be categorized as very feasible.

A museum is an institution intended for the general public that collects, cares for, presents, and preserves the community's cultural heritage for study, research, and pleasure or entertainment. The museum is undoubtedly one of the educational places for the community because it has many historical objects. It provides an opportunity to make the museum a vital place to be developed in a virtual form, such as Augmented Reality or Virtual Reality. However, one problem in developing virtual media is the 3D modeling of objects for interior design in museums. LiDAR (Light Detection And Ranging) is a near real-time 3D positioning technology. A point cloud collects data points in a 3D coordinate system, generally defined by x, y, and z coordinates. Both of these technologies can be used to create 3D object models quickly. The final result of this research is applying LiDAR & point cloud as a 3D modeling technique and assessing the accuracy of using these techniques for 3D modeling of the museum object
