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.

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

Every industry needs IT to improve their business and give faster service to customer. The fast growing of social network (Facebook, Twitter, MySpace, LinkedIn) and Smartphone (Blackberry and iPhone) in Indonesia indicate that Indonesian people are already familiar with high technology and it is the right time to introduce new technology in Indonesia. The problem is, the usage of IT-based system in Indonesia is not optimal. Nowadays, people want to do almost everything faster and more convenient using technology. We know thatuntil now, there are a lot of situations that make people queue or wait to get their need. In this kind of situation, we need something that will change the way to do business, that is in effective and efficient way. NFC (Near Field Communication) is considered suitable as the solution. NFC technology as one of payment systems can increase competitive advantage of the company which implements it and will make it a leader in the industry. This new technology could attract customers, especially Indonesian people in big cities who want to do their transaction in quick and efficient way. NFC is already implemented in Korea and USA as substitution of e-wallet that can help people to make transactions easier and faster. I believe NFC can be implemented in Indonesia to make new trend of doing business.

Abstract

Technology plays an important role in various enterprise business processes for improved customer service, decision making, and means of information exchange. Hospitality accommodation is an example of fields that use information systems technology. This research was conducted in the field of hospitality especially front office system. Using computerized front office system, data about guests will be stored more safely and the reports will be better resulted. The purpose of this study is to analyze the existing problems on a Front Office of a hotel including identifying information needs and designing information systems to improve hospitality services to guests. The method used is analysis and design. Analysis is performed towards library research anddata collection needed for measuring through observation, interviews, and documents related to the information system. Menawhile, design uses object oriented analysis and design (OOAD) method and application programusing MS Access 2010. The result achieved is an application design of information system of hospitality front office that consists of five modules, namely Reservation module, Services module, Housekeeping module,Restaurant module, and Billing module. As a conclusion, a computerized information system of hospitality front office can assist hotels in providing better service to guests, which in turn can increase guest satisfaction.

Abstract

The research analyzed website of Wollongong City Council (WCC) and all the plans done by the WCC. It also showed details an Information Systems (IS) strategic plan for WCC. Although the WCC already had an integrated system, there were several key issues. The framework used to devise IS plan was seven stages (7S) of Gallier and Sutherland (G&S). The approach assisted WCC in locating the current stage of its Information Technology (IT) maturity. From the analysis undertaken, it finds that IT currently is within stages 4 and stage 5 in seven stages. The final result will be the framework of the design as recommendations to the WCC.

Abstract

This research aimed to categorize questions posted in Opini.id. N-gram and Bag of Concept (BOC) were used as the lexical features. Those were combined with Naïve Bayes, Support Vector Machine (SVM), and J48 Tree as the classification method. The experiments were done by using data from online media portal to categorize questions posted by user. Based on the experiments, the best accuracy is 96,5%. It is obtained by using the combination of Bigram Trigram Keyword (BTK) features with J48 Tree as classifier. Meanwhile, the combination of Unigram Bigram (UB) and Unigram Bigram Keyword (UBK) with attribute selection in WEKA achieves the accuracy of 95,94% by using SVM as the classifier.

Abstract

This research applied information system by using Supply Chain Management (SCM) in the pharmaceutical warehouse in Mamasa Regency. The scope of the research was maximized on pharmaceutical warehouse operations and drug distribution to clinics. This research did not focus on cost, profit, lead time, and procurement costs. This system was built using PHP programming language and MySQL database. System development process used waterfall method. It consisted of requirement analysis, system analysis, design, development, and testing. The test system used the xampp 6.2 servers with a black box testing method that involved the pharmaceutical warehouse staff as the end user. The results demonstrate technologies that can be used by physicians to submit drug requests faster and report on real-time drug use (LPLPO). For pharmaceutical warehouses, this system is useful for drug availability, drug management, and response information. This technology can help the health department to perform its role as a supervisory or controlling function (internal controls) of the drugs. This research also gives a recommendation for the pharmaceutical warehouse management in providing benefits for the institutions/companies involved. This research has an insight for the management to realize the importance of Information Technology (IT) to support daily operational activities.
