Abstract

Any difficulty in analyzing sales transaction data is often faced by a company due to the huge number of sales transactions and the limited tools to process the data. It results in losses for the company since it is difficult to estimate the goods supply for subsequent sales. In this paper a data mining application is designed to analyze sales data. Market Basket Analysis is a data mining application that aims to determine most purchased or used products at once by the consumer. The process of Market Basket Analysis is to analyze consumer buying habits by finding associations among products purchased by different customers. The method used in Market Basket Analysis is a method of Fuzzy c-Covering, which is one method to classify the elements of a universal set into partitions of fuzzy sets. This study found that the value of support and confidence is part of the Market Basket Analysis, computed using the Fuzzy c-Covering. The higher the limit, the more selected the analytical results obtained are.

Abstract

This paper discusses integrated model of batch production scheduling and machine maintenance scheduling. Batch production scheduling uses minimize total actual flow time criteria and machine maintenance scheduling uses the probability of machine failure based on Weibull distribution. The model assumed no nonconforming parts in a planning horizon. The model shows an increase in the number of the batch (length of production run) up to a certain limit will minimize the total actual flow time. Meanwhile, an increase in the length of production run will implicate an increase in the number of PM. An example was given to show how the model and algorithm work.

Abstract

The purpose of this research was to review and implement interactive audio visual media used in an educational game to improve elementary students’ interest in learning mathematics. The game was developed for desktop platform. The art of the game was set as 2D cartoon art with animation and audio in order to make students more interest. There were four mini games developed based on the researches on mathematics study. Development method used was Multimedia Development Life Cycle (MDLC) that consists of requirement, design, development, testing, and implementation phase. Data collection methods used are questionnaire, literature study, and interview. The conclusion is elementary students interest with educational game that has fun and active (moving) objects, with fast tempo of music, and carefree color like blue. This educational game is hoped to be an alternative teaching tool combined with conventional teaching method.

Abstract

Wireless technology is one of many technologies that can enable people to communicate with each other by air medium, or rather you can say by radio frequency. This paper discusses about history of wireless technology, different kinds of wireless connection, wireless technology standards, and a few comparisons of different kinds of world’s wireless technology standards. Besides discussing about history about wireless technology and wireless technology that we can use nowadays, this paper also reviews about prediction of wireless technology development in the future for better human life. The purpose of this study is to give a glimpse of view on how the wireless technology develops, the world standard for wireless technologies and work system, the security and characteristic for each wireless technology including advantages and drawbacks, and future wireless technology development.

Abstract

Educational games are the ideal medium to see the extent to which a student's performance will be assessed. However, to integrate educational games has the technical and practical challenges of their own. This study will be directed to the development of a game that can be used to measure the kind of intelligence and capabilities of a child based on the reference of Psychology Howard Gardner's theory kuisinoerThe purpose of writing is the development of gaming applications with HTML5 and JavaScript enabled to measure intelligence. The data taken from the distribution of questionnaires to 30 respondents were randomly. The data were analyzed by finding the average difference between the results of tests using questionnaires to play the game. From these results it can be concluded that there is a gap/difference between the average differences among the results of the two tests.

Abstract

The advancement of communication technology that is combined with computer and the Internet brings Internet Telephony or VoIP (Voice over Internet Protocol). Through VoIP technology, the cost of telecommunications in particular for international direct dialing (IDD) can be reduced. This research analyzes the growth rate of VoIP users, the correlation of the consumer behavior towards using VoIP, and cost comparisons of using telecommunication services between VoIP and other operators. This research is using descriptive analysis method to describe researched object through sampling data collection for hypothesis testing. This research will lead to the conclusion that the use of VoIP for international area will be more advantageous than the use of other operators of GSM (Global System for Mobile), CDMA (Code Division Multiple Access), or the PSTN (Public Switched Telephone Network).
