Abstract

Smartphones have become a necessity. Almost everyone uses a smartphone in a variety of activities. Both young and old are sure to utilize this technology, for a wide range of activities such as doing the work, doing school work or enjoying entertainment. The purpose of this research is to build a casual-action game with war theme. The game is built for Android smartphone that has multi touch screen capability. The research methods used in this research are data collection and analysis method including user analysis with questionnaire. Furthermore, IMSDD method is implemented for game design and development phase including system requirement analysis, system design, system implementation, finally system evaluation. In this research, we conclude that 83.9% participants enjoyed the game with touch-screen as the game control.

Abstract

This article presented empirical finding of the effect of gamification for learning. Evidence in the findings of the empirical study that explores two education games that were developed earlier with a total of 64 participants was presented. The first game was a computer game with historical themes of Ken Arok and Ken Dedes of Singhasari Kingdom. The second game was an Android-based mobile game with Historicity of the Bible themes of Moses. Prior research showed that more than 50 percent of junior and senior high school students in Jakarta demonstrated their apathy to several subjects in their school. They also disclosed that they were having difficulty in following their class in particular with a difficult subject such as History subject. With the popularity of games, the gamification of learning was investigatd to enhance the interest of the students to master a particular subject. The results show that there is a statistical significance increase of the students score and interest in history subject in a group that was using the games to help them in the subject compared to a group that reading books about the particular subject alone 0.001. Furthermore, the participants also reported that playing games was helping them to remember difficult names and event timeline in the historical events

Abstract

Research in the affective game has received attention from the research communities over this lustrum. As a crucial aspect of a game, emotions play an important role in user experience as well as to emphasize the user’s emotions state on game design. This will improve the user’s interactivity while they playing the game. This research aims to discuss and analyze whether emotions can replace traditional user game inputs (keyboard, mouse, and others). The methodology used in this research is divided into two main phases: game design and facial expression recognition. The results of this research indicate that users preferred to use a traditional input such as mouse. Moreover, user’s interactivities with game are still slightly low. However, this is a great opportunity for researchers in affective game with a more interactive game play as well as rich and complex story. Hopefully this will improve the user affective state and emotions in game. The results of this research imply that happy emotion obtains 78% of detection, meanwhile the anger emotion has the lowest detection of 44.4%. Moreover, users prefer mouse and FER (face expression recognition) as the best input for this game.

Abstract

The purpose of this paper is to analyze the system of sales, purchases, and inventory of goods at PT Surya Megah Interjaya and designing the database of sales, purchases, and inventories of goods in accordance with the needs of the company, and to design a prototype application. The methodology used to collect information is by fact-finding technique, which conducted a survey, conducting interviews on related parties, and performed an analysis of procedures and corporate documents. As for database design using the methodology of database-life-cycle, which consists of 3 stages, namely: conceptual, logical, and physical database design. Research conducted, resulting conceptual database design, logical, and physical for business processes of sales, purchases, and inventories of goods. A prototype application is developed to build a working model of a database application that allows the designer or user to ensure the final system will be visible and functioning. With the database design and application development, information needs are met quickly and accurately.

Abstract

By utilizing the augmented reality technology which now develops well, a card game system design and the game prototype are created on through this study Android-based Smartphone. This study is expected to increase the children’s interest to play cards in a modern way, to be utilized as a reference material for business actors in the world, and to be an alternative facility for marketing officers to market their products. The scope of this study is limited only to the system design and the prototype making of the game. The combination of waterfall methodology and a game design by Jesse is used in this study. From the results of the study it is concluded that the augmented reality technology is able to make the game more interesting.

Abstract

The purpose of this research was to develop methods and algorithms that could be applied as the underlying base for developing an object recognition tools. The method implemented in this research was initial problem identification, methods and algorithms testing and development, image database modeling, system development, and training and testing. As a result, the system can perform with 93,46% of accuracy for indoor object recognition. Even though the system achieves relatively high accuracy in recognizing objects, it is still limited to a single object detection and not able to recognize the object in real time.
