Due to the availability of advanced technology in graphics software and hardware, human-computer interaction is receiving considerable research attention in past few decades, particularly game-based interaction. To our best knowledge, very limited first-person puzzle games released in video game market in recent years. In this paper, we present a firstperson puzzle game using the concept of time-travel game mechanic. Firstly, we have designed a set of 3D models and game level using Autodesk 3D Studio Max. We design four puzzles including brick wall, slide, car track, and exit the house/room. Then, a cross-platform game engine, namely Unity utilized to develop the First-Person Puzzle (FPP) game based on changing the timeline past, present, and future. We perform a set of experiments to validate our game that ensures all features are working in gameplay. The user acceptance test proves the performance of our system is better than the state-of-the-art first-person puzzle games.

The introduction of Yogyakarta Culinary game is a game with Indonesia theme with the aim to introducing Indonesia culinary especially focused into Yogyakarta region. A many of tourist from local or foreign country just known culinary that exist and famous in Yogyakarta only Gudeg and Bakpia. This research managed to build a game that can help introduced the other culinary interestingly. This game tested on usability and also Accelerometer sensory used to make character movements. Based on testing which is conducted a people who play the game can be concluded that game is easy to use even tough still have a minor weakness inside the game.

Objective - The success of e-commerce depends on the numbers that is taken into consideration. At the customer side, the trend of online shopping triggers more people to do purchase by online and it also reflect on the business side where they will start to upgrade their business one step ahead by creating e-commerce website. Methodology/Technique - Jakarta, as Indonesia's capital city is the place of the survey of the study with 100 respondents where the result from the questionnaire feedback will portray on what are people take into consideration about the website and justification as well as the result provide a better understanding about web user behaviour or in the other words willingness to stick, trust and understand the consequences of perceived risk to a website. Findings - The result gives the suggestions to the businesses to create an overall reliable website design and structure to engage their customer and translate to the success of e-commerce. Novelty – However, the lack of overall website structure will affect to the web user behaviour which indirectly impact to the success of e-commerce. Novelty - The finding of this study would enhance understanding of the issues of reward system among employers in manufacturing organizations which can influence the effectiveness of employee creativity. It also will be beneficial to the management in puttingsuch efforts to increase employees' creativity. Type of Paper - Empirical Paper Keywords : Stickiness; Perceived Risk; Trust; Online Purchasing Intention; Website Quality; Web User Behaviour

3D spatial modeling is one of the most important issues in 3D GIS research. It involves the definition of spatial objects, data models, and attributes for visualization, interoperability and standards. Real world complexity leads to different modeling approaches, as seen in different GIS applications. This paper provides some review of the problems, challenges and issues pertaining to the 3D GIS problems, especially in the handling and managing of 3D solids in DBMS. The paper also describes 3D spatial operators in DBMS and presents results using a simulation dataset. At the end of the paper, we provide and highlight requirements and recommendations for future research.

In this paper, we discuss the problem of 0D feature-in-3D planar polygon. It has been recognized that 3D union and 3D intersections are among important spatial operators in 3D GIS. A 0D feature-in-polygon test is one of the problems in 3D GIS. Though it is a classic problem, however, it has not been addressed appropriately in the literature. Moreover, the 0D feature-in-polygon query is rather complicated if it is implemented into 3D spatial information system. From the aspect of 3D spatial analysis, the general 0D feature-in-3D planar polygon problem should be formulated in a suitable way. Our basic idea is to solve a general 0D feature-in-3D planar polygon problem that includes all special conditions. The method addresses an essential mathematical algorithm that applicable for real objects and provides an approach for implementation in further 3D analytical operation, e.g. 3D union or 3D intersection for 3D GIS.

Nowadays, 2D GISs are common and their related theories, concepts and models like for geometrical modeling and spatial relationships of objects are also well addressed and investigated. Most of the tasks related to 2D GIS applications are quite straightforward and relatively easy to handle. 2D GIS spatial analysis such as proximity analysis or proximity computation, network analysis, overlay function, neighborhood function, metric measurement and other analytical operations are also well understood and well researched by the GIS community. However, problem started to surface once we move towards 3D domain, i.e. to add an additional dimension to the current 2D GIS situations such as in spatial data modeling, analysis and application. Manipulating and handling spatial objects become more complicated as we move toward 3D. This paper attempts to address one of the problems in 3D analytical operation, i.e. 3D proximity analysis.
