Abstract

The aim of integrating the information system for Community Health Center is to create an integrated information system for managing all data processing between different community health centers, namely district community health centers with village community health centers. Methods used in integrating community health center information system are Identifying Information Requirements, Identifying System Requirements, Modification of Information System Application Design (integrated), Modification of Information System Application, Application Test, Refining Application, employee training, and the last is implementation of integrated community health center information system. The result of this research is development of integrated community health center information system which in the past is only integrated in the same location, and now integrates between community health centers in different locations. The steps are development of database from local database into distributed and central database; development of admission transaction, clinic data, and pharmacy data modules which makes it possible for synchronization of patient data between distributed database with the central database. Therefore, patient data is still stored in both databases.Keywords: integration, information system, community health center

Abstract

This study discusses specifically the encryption mechanism that maintains the integrity of the game data on online games. The purpose of this study is to implement symmetric key encryption and checksum for score calculation. There are two methods conducted in this study: analysis and design. The analysis method isperformed in two ways: analysis of existing systems and analysis of literature study. System design method used is prototyping. The results obtained are implemented on online game competition ‘Expedisi Indosat’ through Facebook from 3 – 30 July 2011. The implementation of symmetric key encryption mechanism and the checksum is useful to maintain data integrity on games especially the results score when the game is running and when there is data transmission from the client to the server.

Abstract

The research wanted to find the workflow and solution by developing m-learning object for Android and iOS-based smartphone and tablet that supported interactive multimedia. The research began with analysis, design, implementation, and evaluation. Currently, the learning objects were not compatible with mobile devices. To overcome this problem, the research focused on designing the instructional design for m-learning and the development of interactive multimedia. Instructional design was created by the collaboration of the subject matter expert and instructional designer. M-learning was designed using UML and developed using Adobe AIR technology. The implementation of this research was a prototype of m-learning for concept of cost in Faculty of Economics, Bina Nusantara University. Then, the evaluation was conducted by distributing m-learning object to 32 selected students by simple random sampling in their first week of lectures in February 2014. The observation was conducted during m-learning object installation and initial learning process. At the end of the second week of the experiment, summative assessment and questionnaire were given to students. The results show that m-learning object is compatible with mobile devices. The students also say that m-learning is easy to use and helpful for their learning.
