Abstract

Mahar Agung Organizer has many parameters in selecting candidates that cause a lot of time during manual processing. Project manager's selection in February 2018 was then estimated at more than five hundred job applicants. In the August 2018 official crew selection, it was estimated that job applicants reached one thousand six hundred candidates. In addition, there was no process of classifying the types of events suitable for official crew after being accepted, causing the project manager to review the results of the interview to place the crew official in the list of events. The absence of a concise page that can display information related to official crew work performance to assess official crew performance is also one of the problems that is expected to be resolved through this research. This research will be conducted using an Object-oriented (OO) approach that will use Use Case Diagrams, Sequence Diagrams, and Class Diagrams in making systems. The development cycle uses the Prototype method by doing two iterations according to the agreement in the beginning with the stakeholders. This system will have three main features. The first feature will be implementing selection of candidates with Profile Matching. The second feature is a function for placing candidates who have been accepted into their divisions using the Naive Bayes algorithm. The third feature is displaying official crew performance in the form of dashboarding information. Validation testing using Black Box produces 100% validity. Unit testing and integration testing using White Box is in accordance with expected result.

Abstract

Online marketing or often called digital marketing is marketing with the concept of promoting a product or service through internet-based media, one of which is a website. The existence of a website raises new problem, namely the difficulty in recognizing website visitors. The use of website to improve marketing strategies needs to be done by recognizing website visitors which will be the lead for a company. Without recognizing the website visitors, the salesperson cannot determine the customer to be contacted. To overcome these problems, a system of monitoring leads is built on the website by applying the waterfall development model. The technology used in this research is the laravel framework which are implemented using the PHP and Javascript programming languages. This research produces a monitoring lead system that can monitor leads, recognize the behavior of website visitors, find out the recommendation of leads, and conduct lead management. In the calculation process, the recommendation of leads uses the weighted product method which is a decision support method that uses weighting, where alternative values and predetermined criteria are needed. This weighted product method is expected to provide recommendation of leads in the form of rating so the salesperson know which leads should be followed up. Testing is done by using the white-box and blackbox methods which show the results that the system functions are in accordance with the main functional specifications, which is displaying various lead information. Usability testing produces a value of 91.67 which indicates that the system has made it easy for users.

Abstract

Review written by customer toward a restaurant can be useful for prospective customer or owner of the restaurant to knows the others opinion about the restaurant. However, this can cause a problem if customer review comes in large number. Automatic text summarization system can be a good solution to this problem. One of the best known method for automatic text summarization is TF-IDF weighting. Yet, this method also has a weakness for having tendency to extract long sentences as summary which has high score for contaning many words. In this research, writer propose an approach to use automatic text summarization which not only extract sentences based on its weight but also the ones which covered some words. This is because in the sentences which considered as summary, exist some words which appear together frequently (frequent itemset). Therefore, in this research Weighted Frequent Itemset method is used to summarize customer review for restaurant. This method summarize text by extracting sentences which covered many frequent itemsets and has high sentence relevance score. The result from the test shows that summarization using Weighted Frequent Itemset Mining method archieve average F-measure 0.279.

Abstract

Plagiarism is an inseparable thing from an academic environment. Various motivations including working part-time and social dilemmas contribute to the high percentage of plagiarism at the university level. Handling with the plagiarism detection method has many disadvantages, such as the emergence police-criminal paradigm, value-oriented mindset, and technical weakness such as inability in analyzing translated documents. Hellas, Leinonen, and Ihantola's research with the plagiarism prevention method has several shortcomings, namely ignoring the process of work so that students can be cheated by buying assignments, the analysis at the end makes students able to cheat during assignments, no any log produced so the teacher can't assess student effort, and the software is tied to a particular platform. This research aims to perfect previous research by adding a snapshotting process that records document changes, user activity logging which records student activities, and build the systems with agnostic properties so that there is freedom to choose the form of tasks and the software that will be used. The system is tested using unit testing, integration, validation, automated testing, and compatibility. Unit testing and integration are valid and exceed 70% code coverage, validation testing in 32 test cases are valid, and compatibility testing shows the system is running well on six common desktop environments. Valid automated testing that contains no errors can speed up the testing process.
