Abstract

Applications commonly used to solve the equations of dynamic analysis produce output that is less accurate because the use of mass implementation is less precise. Most of the applications are commercial and require the installation process before they can be used. The authors developed an application that uses website as the user interface, so that it can be accessed easily and does not require any installation process. The Website was created by using a more precise mass implementation so that the output becomes more accurate with simulated deformation and structure deflection.The Authors designed the website so that a user can have an account to make a project that is public or private, and an admin can manage the member data. Input process data are entered into tables with tabs such as node, properties, elements, joint mass, joint loads, ground acceleration, process so that the user can perform data input easily. Dynamic analysis calculation is performed by processing the input data using the Newmark method involving the creation of stiffness, mass, damping matrices the initialization of displacement, velocity, and acceleration the calculation of integration constants, the creation of element stiffness matrix, the calculation of displacement with time dependent, the calculation of displacement, velocity and acceleration.This dynamic analysis website generates outputs like all mentioned matrices in each element,  structure stiffness matrix, structure mass matrix, and displacement vector that conform with the exact solution. Results of displacement vector are  used to display the simulation of deformation and structure deflection at each time interval so the the structurak changes are observable from the beginning to the end.

Abstract

Visual Novel is an interactive fiction game comprised of static images, sounds, and video combined. However, almost all of visual novel available are only accessible after completing the installation process on the platform defined by the development of that visual novel. Besides, authoring tools specialized for visual novel making are mainly based on desktop. Through this development, the authors would like to provide a widely accessible application which is available over the web and delivering ease of use of visual novel authoring tool. Availability of playable visual novel is also included to be one advantage of playing visual novel hassle-free.The results obtained from this application, among others, can upload and manage files necessary to be used in the visual novel project as its resource, create a visual novel through the provided editor, publish created visual novel, and play all published visual novel.

Abstract

PT Kirana is a well-known travel agency in the city of Malang. The company provides several kinds of tour packages at affordable prices. Kirana Travel has several routes, among others: Surabaya, Mojokerto, Malang and Juanda. At this time, the existing business system is still manual, recording orders placed are still manual. The ordering is done over the phone, then the admin noted that customer address will be picked up. After noting all existing orders, admin notify the driver addresses will be picked up. Drivers do not know the best route to be taken. At the time of the operation of the fleet, the driver only has the addresses of customers who will be picked up one by one. Currently operates a fleet of office parties and customers usually do not know where the position of the current fleet.This application is created using eclipse program and phpMyAdmin as database storage system. The application is divided into three applications: application for customer, application for admin, and application for the fleet. Customer application used to perform the ordering. Admin application is used for schedule and order management. Fleet application used to see pick-up route.From the results of testing of applications, shows that this application can run well on mobile devices that use the operating system andorid. Because every customer will use mobile devices to do the ordering process. So Kirana Travel reservations will be easier in the future.

Abstract

With the rapid development of technology, the need of entertainment keeps going up. On the other hand activities and businesses among the vast majority of people are increasing. The existence of smartphone helps a lot of people to increase their productivity. Besides the general function of it, smartphone can also be used for gathering information and as an entertainment system.Android and iOS are the top 2 operating system that most people used. Using a game engine called Cocos2d, a game will be made for iOS operating system. Artificial intelligence with Finite State Machine method will be applied to this game on 5 NPCs, since the game is intended for single-player.With SpriteBuilder as an editor for user interface, Objective-C as the programming language and Xcode as IDE. A video game called Galactic Defense has been created by adapting its concept from a traditional game called "Bentengan" (or Fortress in English) which has been modified to adjust the handheld device. This game has 2 difficulty levels and a save game feature.

Abstract

X University is now growing increasingly large and has a wide variety of information systems to run its operations. One of the most important servers in X University is www.xyz.ac.id. That URL is one of the URLs that are frequented by the public outside to get to know closer about X University in general. Security of web server is usually a matter of an administrator. Sometimes, security issues or server application system and the importance of securing web server neglected only realized after the disaster. Without a good security application systems, the application of technology would be very dangerous as good as any institution or organization itself. Therefore, it takes a server security evaluation and conduct vulnerability mapping to be wary of the security server.Based on the background of the problem, it is necessary to evaluate by using penetration testing. In addition, this study also uses the guidelines of the module CEH (Certified Ethical Hacker) and the official web Acunetix. Testing of this thesis is aimed to find the weaknesses of existing servers. Some problems were found after testing, among others: the weaknesses found pretty much where any weaknesses have different handling, ports should not be open even open, and less important public IP should not be open.The solution provided to overcome these problems include: the use of Acunetix standards can be maintained and continued, testing will be done more than one time, to upgrade web server to a newer version periodically, to filter the existing port, increasing the level of web security server, periodic maintenance, and security testing regularly and periodically, either by consulting the relevant field or using a guide (like Acunetix, CEH, OWASP).
