Abstract

The purpose of this research was to identify problems, analyze needs, and develop management information system especially the process internal control of asset management on Direktorat Jenderal Sumber Daya dan Perangkat Pos dan Informatika (SDPPI - government communication and informatics organization). This system development used the System Development Life Cycle (SDLC) method which refers to 4 phases. Those were initiation and business feasibility, requirements definitions, functional design, and verification. The analysis used to support the research methods was Enterprise Architecture (EA) and SWOT. The analysis was conducted on business process that was running at the moment. The results show that the management information system in the form of web-based applications can help the process based on activity logging assets, assets allocation, complaints, and user guide in accordance with the needs of the Direktorat Jendral SDPPI. The design of this application can also help the existing asset management process to become more efficient and effective.

Abstract

To provide convenience for the user that frequently read the news, a system to gather, classify, and provide news from several news websites in one place was needed. This system utilized a recommender system to provide only relevant news to the user. This research proposed a system architecture that used vector space model, and Rocchio relevance feedback to provide specific news recommendation to user’s feedback. The results are that the proposed system architecture can achieve the goal by using five levels of feedback from the user. However, the time needed to gather news is increasing exponentially in line with the number of terms gathered from articles.

Abstract

This research evaluated the factors that influenced the behavioral intention to use a mobile application. The case study used was SedayuOne mobile application. The method used was the questionnaires using Unified Theory of Acceptance and Use of Technology (UTAUT2) model. The questionnaires were sent to the 342 members by using email. The result shows that the user habit is the highest factor that influences the user behavioral intention to consume the SEDAYUONE application.Therefore, to maintain the user behavior, the company must know the user habit and consider promotional strategies to enhance the attractiveness and maintain customer loyalty.

Abstract

The purpose of this research was to build cloud computing referring to Roadmap for Cloud Computing Adoption (ROCCA) model so that the best strategy could be implemented in PT Matrica Consulting Service. The implementation of cloud computing had five stages modifications ROCCA adoption model. Those stages were analysis, design, adoption, migration, and management. Data were taken from distributing questionnaires and conducted interviews with R&D Manager and analyzed using SWOT analysis. The result is the implementation of cloud computing models, and implementation of private cloud and Software as a Service (SaaS) needs to be modified so it can be implemented properly. The implementation canincrease the performance PT Matrica Consulting Service based on the characteristics of the cloud which is flexible and secure to be accessed as long as it is connected to the Internet and maintained properly.

Show Abstract | Download Original | Original Source | Check in Google Scholar | DOI: 10.21512/comtech.v8i3.3876

Abstract

This research proposed new method to improve performance of WSN. It used network coding on transmission scheme. The researcher had modified the existing network coding multipath routing for a novel node selection to own residual power node in network coding routing mechanism and to improve reliability of a WSN. This routing mechanism was placed in router for routing purpose. Then, Software network simulation method was done by using OMNET++ platform and MiXiM Framework library. The result shows that proposed method to select nodes and execute network coding succeeds on improving performance of WSN like the reliability compared to the previous method.

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.
