Abstract

Sistem inventory merupakan suatu kegiatan pengolahan data barang pada suatu ruangan. Sistem Inventory berperan penting bagi suatu instansi dalam pengolahan data inventaris untuk mengoptimalkan pengawasan pada keuangan Negara. Sistem pengolahan data inventaris di berbagai instansi masih mengunakan Microsoft Excel sehingga data belum terarsip secara optimal. Pengolahan data tersebut dapat dipermudah dengan mengembangkan Sistem inventory dengan menggunakan metode Neuro-Dynamic untuk menghindari adanya overdemand dan oversupply. Metode pengembangan sistem yang digunakan adalah metode waterfall. Sistem yang telah dihasilkan yaitu suatu sistem yang memberikan informasi tentang data barang di jurusan Ilmu Komputer di Universitas Lampung. Pengembangan sistem inventory dengan menampilkan beberapa fitur seperti Laman Inventaris, Laman Kebutuhan, Laman Peminjaman, Pengembalian, Laman Kehilangan, Laman Reporting Data Inventaris sebagai pengolahan data inventaris dan telah berjalan dengan baik. Sistem dapat membantu proses kerja staff dalam pengolahan data inventory dan pembuatan laporan inventory kepada pihak jurusan. Sistem inventory ini diimplementasikan dengan menggunakan database MySQL dan bahasa pemrograman PHP. Kata kunci: Sistem Inventory, Metode Neuro-Dynamic, PHP

Abstract

Active student of computer science system is a system developed based on academic information system (siakad) which is managed by The University of Lampung. The system is built to calculate the number of active students based on data that has been inputted by students into the KRS at the beginning of the semester. KRS data is used to build the system to calculate the number of active students majoring in Computer science. The system was developed using PHP and MySQL, and tested using the Black box and White box testing.

Abstract

Exam is a test or evaluation that goal is to determine one’s ability. Trials conducted in the school who are generally still conventionally which the implementation is using paper and lasting correction process. The correction process can be facilitated by making the online examination system in school. System development method used is the waterfall method. Process method waterfall in the process is done sequentially. System that superbly produced which is a system that can be accessed by three users are administrators, teachers, and students. Development of online  examination system in school to facilitate the teachers in terms of correcting for direct assessment process can get online after the exam is over. This test system is implemented by using database mySql and php programming language.

Abstract

Samba is a re-implementation of the SMB (Server Message Block) / CIFS (Common Internet File System) from Windows NT used for providing shared access to files, printers and miscellaneous communications between nodes on a network. Samba uses the client- server mechanism whereby a computer will act as a server and should always be active to provide services to users. As an alternative, wireless router is used to replace computer server functionality to provide the same services as computer server did. By using OpenWrt, wireless router can be installed with Samba server. To simplify the installation and configuration process of Samba server, we designed a Bash shell script to automatically installing and configuring Samba server on OpenWrt router.Keywords: bash, networking, OpenWrt, router, samba, shell script

Abstract

Online attendance list is one of the new breakthroughs to record the list of attendees using computer technology and internet. In general, online attendance list is done by entering the username and password that have been registered in the system within the limited area. This research developed a web based attendance recording system with login area restriction. The system not only will check the username and password entered by user but also detecting the IP addresses to see whether they allowed to access the system or not. If the users succeed login to the system, it also means that they will be listed in the presence list and if they fail the system will not record their presence. The system produce the report of attendance list for given period and can also be used to protect information access                                                                                       Keywords: attendance list, information systems, ip address, login area restriction.

Abstract

The academic supervisor help collagers to finish their study well and efficient depends on their condition and potential. The allocation of academic supervisor in computer science major was done manually,  it makes data processing become over late. This study, develop a web based system to help determine the academic supervisor for each collager, and to represent it in a graph. This system is developed in PHP programming language. The system outputs are collegers data and their academic supervisor, and the graph of collegers data for each supervisor. The system also represent the data result in a format of SK proposed format.The system development use prototype method. The advantage of prototype method is the system can be  develop as expected by user. First prototype produces some functions such as login, lecture and colleger data input, clear data academic supervisor, edit data academic supervisor, and devided colleger data for each supervisor. Second prototype produce some addition function such as print complete supervisor data, print supervisor data, and show supervisor data graph.Keyword : Academic Supervisor, Prototype Method

Abstract

Tree Structure is used widely to represent problems in daily life, especially in computer science and technology. One method that is used to represent a tree is Blob Code. In this research, we developed an application to Encode and Decode Tree using Blob Code. This application aims to simplify the process of changing tree into a blob code (encode) and the process of changing Blob code into the form of tree (decode). Keywords: Encode, Decode, Tree, representation Tree, Blob Code.

Abstract

Security is an important aspect in digital data transmission, and steganography is one way for hiding a secret message in such a way so that others are not aware of the existence of something in the message. In this research, we built a digital steganography system using web-based with Adaptive Minimum - Error Least Significant Bit Replacement (AMELSBR) method. The media to hide the message is on the form of .jpg, the output is on the form of .png, and the message is on the form of .txt. The procedures for applying AMELSBR method are Capacity Evaluation, Minimum - Error Replacement and Error Diffusion. The result shows that the AMELSBR method is able to manage for hiding and restoring files without causing excessive distortion (noise) in stego image. The AMELSBR method has a possibility of returning most files to image manipulation such as the change of image Brightness and Contrast with the black color dominant (rgb(0,0,0)), white color dominant (rgb(255,255,255)).

Abstract

Markerless Augmented Reality (AR) is a term for an environment that combines real world and the virtual world, where objects in the real world can be recognized through the position, direction and location. Markerless AR technology can be used to interactively visualize information, especially when the technology is combined with a mobile communication device such as a smartphone that has the Android operating system. Camera features, internet, accelerometer, digital maps and GPS (Global Positioning System) on Android devices can be integrated so that AR technology can be implemented. In this study, Markerless AR technology is implemented in the Faculty of Mathematics and Natural Science (Science) University of Lampung buildings. The aim of this study is to create an application that provides information about the buildings, it is show Faculty maps and information about the Natural Sciences accessible via Android smartphones. This application is designed and then implemented using the Java programming language for Android and BeyondAR framework support to detect and display the AR object and the Google Maps API to display a map of the Science Faculty. The results of data test using Equivalence Partitioning test shown the application functionate well according to the analysis. In addition, based on questionnaire data, that the application is a user friendly application (with an average value of 4.31 / very good), and interactive (with an average value of 4.23 / good).Keywords: Android, Application, ARMIPA, Augmented Reality, Maps, Markerless Augmented Reality
