Perumusan Dan Penyelesaian Persamaan Kesetimbangan Dalam Analisis Dinamis Pada Bangunan Tinggi Berbasis Website

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

Eksplorasi Pemanfaatan Docker Untuk Mempermudah Pengelolaan Instalasi Komputer Di Laboratorium Komputer Teknik Informatika Universitas Kristen Petra

Docker is an application that is based on open source technology that allows developers or anyone to create, run, do experiments and launch application in a container. Docker make the process of packaging application components together quickly in an isolated container, so it can run in local infrastructure without changing configuration on the container. Docker also very light and fast when compared to hypervisor-based virtual machine.Department of Information Engineering of Petra Christian University has a considerable number of students, which the number usually hundreds, while the number of computers in the laboratory of Department of Information number is not as much as the students. With this amount is not comparable, then some students work in the same computer alternately. It makes the students cannot be comfortable working on one computer, because configuring a computer on every lesson is different. Therefore, implementation of Docker application carried out in the laboratory.Docker implementation and RAID storage system and after implementation, testing was done by measuring the speed of docker image transfer. The resulting data were used to development of container system and evaluate the speed of RAID storage system are used

Evaluasi Penggunaan Linux Router Untuk Pembatasan Bandwidth Aplikasi Internet Tertentu

According to Cisco report in 2015, Internet USAge has increased more than five times in the last 5 years, and it was projected to increase three times over the next 5 years. Increasing use of the internet is mostly caused by certain internet applications such as Flash, MPEG, video streaming, and P2P file sharing. Therefore, bandwidth configuration with traffic shaping method in Linux is needed in order to provide the needs of the Internet in accordance with user class. nDPI is used for classifying the data traffic in the Internet network.Work on the thesis focuses on the evaluation of the use of nDPI on bittorrent P2P applications. The evaluation was done using iptables to perform the data traffic marking and traffic control (tc) to do the bandwidth shaping. Bandwidth monitoring used iptraf applications on Linux and Networx application on the client.Based on testing performed, traffic shaping with nDPI coupled with cache successfully limited the bandwidth USAge of bittorrent P2P applications. The nDPI with cache was evaluated in different cache sizes and bandwidth limits. nDPI with size cache of 1024 entries is recommended. nDPI can not fully classifying bittorrent traffic correctly

Pembuatan Aplikasi Penjadwalan Dan Reservasi Untuk Penggunaan Private Cloud Computing

Cloud computing is a new technology that is being hotly discussed by experts in information technology. Cloud computing technology is here to address the challenge of more efficient computing technologies. So an idea has come about to build a cloud system in the Petra Christian University's computer laboratory. However implementing the cloud could interfere with the use of existing lab. The application aims to help the user manage the cloud system to run according to the desired schedule.The application development involved evaluation on the scheduling system, enhancement on the filter scheduler to accommodate a time schedule, and creation of the web-based user interface to manage the time schedule (in the form of a calendar).The application can restrict the OpenStack's instance deployment only on the time schedule allowed by the system administrator. In addition, the system scheduler has negligible latency (overhead), so that it will not affect the system scheduler's performance

Pemanfaatan Teknologi Near Field Communication Untuk Penyampaian Informasi Multimedia Di Museum Negeri Mpu Tantular

Museum is a place to store a variety of cultural heritage that can be used as an educational attraction for the community and study materials used by academics. But unfortunately the public interest to make the museum as a tourist destination is very low. Therefore we need innovation to attract people, and in this case the innovation made in the utilization of NFC technology in android . NFC technology is currently being highly developed and has been used in many applications, so the utilization of that technology is expected to dispel the impression of being outdated and unattractive, commonly attached to the museum.This application will be divided into two, namely mobile applications for visitors that have been developed using Android Studio software and web applications for administrator that developed using Notepad++ and MySQL database. This mobile applications can deliver information of objects in the museum in the form of text, video, and audio by scanning the NFC tag which the results of the scan will direct the application to retrieve data from a web application as a server for database management. This application can also display museum's profile, museum's events, museum's maps, and mini games. From this application museum can also obtain statistical data which can be useful for the development of the museum that can be accessed from web application.Based on the results of implementation which has been tested, this application was able to deliver the information in the format of text, image, audio, and video by scanning NFC tag. In addition, from the application feasibility tests on random users, all respondents express that they are more interested to visit museum with the presence of this application
