Abstract

The security system within a company is the top priority, one of its application is in web media, where it exist various confidential information in it, such as user information on the company PT. One Standard Group PTE LTD must be kept confidential not to fall into unauthorized parties, therefore a security system to address the information security is needed. The security system of modern symmetric key cryptography algorithms is considered to be able to overcome these problems which are generally divided into two, namely Data Encryption Standard (DES) dan Advanced Encryption System (AES). From the two algorithms, the author makes comparisons to obtain a more efficient algorithm in terms of security and times. The method that the author used in this research is Extreme Programming Research Methodology, with a qualitative methodological analysis technique, and in data collection author uses direct observation and literature study. The system that the author created applies additional security for user information which will be directly stored with the AES method and the DES method and the system will display the processing time of both. The conclusion that the author can achieve from this thesis is AES method cryptographic algorithms are more secure than the DES method because the AES method has double protection, but from the time aspect efficiency, the DES method cryptographic algorithms are more efficient.

Abstract

Technology developments are growing rapidly and give benefits in various aspects of human’s life, especially in education. The technological development in education can be used to predict bullying. This research is conducted because the society still underestimates the case of bullying, using manual way to know the potency of bullying, and some schools in Indonesia still have not given any test to predict the bullying among the students. The researcher aimed to design, construct and implement the expert system. The researcher uses system theory, experts, expert system, web, research method and bullying theory. In order to predict the potential of bullying, this research implements the forward chaining method. The data is collected by observing and interviewing counseling teacher from Santo Yoseph Senior High School, and by reading books, journals and websites as references to support this research. The researcher implements prototype model approach for this research. This Application is created in order to predict the potential of bullying in Santo Yoseph Senior High School students based on the phenomenon and calculation from the Counseling Teacher by using Forward Chaining method, and explaining the application process in the form of Use Case Diagram, use case description, sequence diagram, class diagram, entity relationship diagram and site map. The Application development is expected to be useful for Counseling Teacher in Santo Yoseph Senior High School to predict the potential of bullying among the students. Keyword : Forward chaining, bullying, expert system.

Abstract

Techonological development in today have helped in field of education in terms of delivering informations.Delivery of information or the dissemination of information at this time has begun to apply computertechnology as a tool for help, but not yet supported by interactive information searching media.Using naturallanguage processing for extracting keywords from a sentence can be applied with Application ProgrammingInterface from Dialogflow and will be applied in form of a chatbot and will be built using React framework.This research will be conducted with Waterfall method, data gathering done by observation, interview, surveyand information from related parties. The chatbot or system design will be built with UML design. Chatbotapplication has successfully met the standards with the success rate of 80%. This chatbot aims to provideconvenience for students in obtaining information about academic activities.Keywords: Natural Language Processing, Chatbot, Dialogflow, React, Application Programming Interface.

Abstract

This research is caused by the problem of an absence of a service about improving motivation and achievement in working environment at Koding Next Company. The author applies the concept of gamification on this service. The conceptualization of gamification in this service uses 9 elements of motivational affordance, which are point, leaderboard, badges, clear goals, feedback, reward, progress, and challenge. The motivational affordance affects the psychological outcomes and behavioral outcomes. The author conducts field studies, interview to the users who will be directly involved with this service, and a literature review of previous researches that share the same topic. Through this research, the author finds out that the concept of gamification can be applied with PHP through API as the service. The data in this service can be accessed by web and other platforms to support the concept of gamification. Through the research process and the making of the service process that has been going on, the author concludes that this service can apply Gamification as a Service at Koding Next Company. This service is capable to improve the motivation and achievement of employees. Kata kunci: gamification, service, gamification as a service, api

Abstract

At  present  the  development  of  digital  technology  and  telecommunications  is  progressing  very  rapidly throughout the world, making almost in every country always closely related to technology in their daily lives, including Indonesia. Utilization of computer applications in everyday life has become a necessity. For this reason, the issue of security and confidentiality of data and information is very important. Personal data should not be known by others to suppress the occurrence of data that is misused and used. It needs to be protected and restricted from anyone who can access important data. In this study, the authors developed a login data security system application with the AES algorithm method to assist individuals in maintaining important data, especially passwords they have. In addition this application uses a MySQL database as a means of storing data, and PHP, HTML as a programming language, and CodeIgniter as a framework for supporting system development. This  research  was  conducted  by  utilizing  the methods  in  collecting  data,  namely,  literature  study  and documentation. And utilizing the AES algorithm as a data analysis and measurement technique The design of the application that the authors propose will include a system architecture, a system description using UML diagrams, namely use case diagrams, activity diagrams, and class diagrams, there is also a design interface and program flow design to explain how the program can run and how the program displays when viewed by the user, and there is a system implementation that covers hardware specifications, installation guides, and usage guides. The cryptographic application that the authors produced through this research is intended to be able to provide a security system solution that can maintain data security on the login system so that users can stop using passwords that are weak and repetitive, so users can keep their passwords safer.
