Abstract

Mobile device or known as smartphone have a role for human communication. Everyone can communicate even if they in long distance with using smartphone. But, the crime in digital communication keep happening.  On of them is tapping. Tapping is a action to monitoring an information that sent by unauthorized people of that information. A way to solve tapping is do cryptography to informatin to be sent. Cryptography is generally devided into two things, that is encryption and decryption. Encryption is a process to convert a text into another format. Meanwhile, decryption is a process to convert back a information that has encrypt into original form. One of cryptography algorithm is symmetrical algorithm, which is an algorithm that uses the same key for the encryption and decryption process. Therefore, message cryptographic application are designed using symmetrical algorithm. The analytical technique used is Unified Modeling Language (UML) to modeling the system. In system designed, author using MySQL for database design dan using Android Studio as an Integrated Development Environment (IDE). From this entire research process, is expected can resolve tapping of the information that send by user. Keyword: application, cryptography, encryption, decryption, key

Abstract

At present, the development of the gaming world is very rapid. This is reinforced by the source of newzoo.com which provides game development statistics from 2012 to 2019. These developments can not be denied anymore, because the game is indeed one of the hobbies that are most interested throughout the world. The development of existing games is not comparable with the mobile market that exists at the moment. This is evidenced in data from newzoo.com which contains that the sequence of platforms with the largest market currently is as much as 51% mobile, 25% console, and 24% PC. Data from wepc.com states that 53% of games are made for PC platforms, 37% of games are made for mobile platforms. The author uses a descriptive research design and research design in writing this study. The method of data collection used is by tracing the literature and articles that can be used as material to compile research. UML is used as a system analysis technique used to describe and document the design of game applications. C # programming language to do program code and apply navigation mesh. The resulting application is an offline survival horror game that uses a navigation mesh method with the Android platform. The conclusion of this study is that the application of the navigation mesh method is very supportive of the search path and for chasing and location of players. Suggestions from this research are that the addition of the FOV method for several monsters is needed so that the game challenges are more varied. Keywords: Games, Offline, Survivval Horror, Navigation Mesh, Android

Abstract

In a running system, CV Sumber Sahabat have computerization system that limited to purchase and sales which a simple report. CV Sumbe Sahabat still does not have web-base or e-commerce sales, where sales can only be done directly and through by sales. So that the author designed a web-base sales information system with the aim of helping CV Sumber Sahabat in wide scope of selling. The author uses descriptive research design as a research design, While the data collection method used is the method of interview, observation, and literature study. The author uses the Unified Modeling Language (UML) as a system analysis technique in sales information systems. The system design information technique used is the PHP Programming Language, DreamWeaver CS6 V 12.0 Editor and MySQL database design. The results of the research carried out in the form of a web-based sales information system at CV Sumber Sahabat which can be used to assist in selling goods in a wider scope. The page consists of inventory and sales transactions, inventory reports, daily sales reports and monthly sales reports on CV Sumber Sahabat in order to help employees obtain information and process better and quality data.

Abstract

Android smartphone is one of device that has been used a lot by society. This device is also often used as a medium for information exchange. Android device also has a relatively small memory storage compared to laptop and computer. File compression is a technique used to shrink a file’s size. Using this technique, a file inside an Android device then can be shrunk so it can save the storage space. Besides that, this compression technique is also useful to speed up information exchange because the size of information sent become smaller. The compression algorithm used is Lempel-Ziv 77. This compression algorithm is able to produce a compressed file with 0,4 ratio compression on text and bitmap image filetype. This compression application is effective to be used on text and bitmap image file if the user wanted to save their storage space. Keywords: Android, Compression, File, Lempel-Ziv 77, Lossless
