This study discusses specifically the encryption mechanism that maintains the integrity of the game data on online games. The purpose of this study is to implement symmetric key encryption and checksum for score calculation. There are two methods conducted in this study: analysis and design. The analysis method isperformed in two ways: analysis of existing systems and analysis of literature study. System design method used is prototyping. The results obtained are implemented on online game competition ‘Expedisi Indosat’ through Facebook from 3 – 30 July 2011. The implementation of symmetric key encryption mechanism and the checksum is useful to maintain data integrity on games especially the results score when the game is running and when there is data transmission from the client to the server.

Article purpose was to make computerized system useable for running the company operational and the activity always needs information. The data collecting method were done by literature study, field study, and documentation study. Analysis and design method consisted of four phase, which were investigation system, analysis system, design system, and implementation system. The result from observation was the company needs transaction recording system that computerized so every selling or buying transaction of foreign currency can directly update the inventory. The conclusion is that the up-to-date selling and inventory information can help manager in making decision.

The development of accounting information technology has actually been going on for a long time. This is because the use of technology in accounting can save time and costs and the use of technology in accounting is considered very efficient. In order to provide accounting information, an information system known as the Accounting Information System (SIA) was created. A good accounting information system requires a good system design too. At  Cooperative, data processing is still done manually using Microsoft Excel, which makes this cooperative vulnerable to recording errors. Apart from errors in recording, delays in delivering information can also occur due to ineffective recording. Therefore, this cooperative needs to use a cooperative accounting information system. Which this system will later be able to assist the cooperative in carrying out the existing transaction process in the cooperative effectively and efficiently and well computerized. Based on this, this study aims to determine the financial reporting accounting information system that has been implemented by the Cooperative and to design an application-based savings and loan cooperative financial reporting accounting information system in accordance with the needs of Cooperative. This study used qualitative and experimental methods, while the application design method used was a waterfall. The system development method used in this research is Netbeans IDE with Java programming language and Mysql as database storage and iReport to design financial statements.The results obtained from the analysis and design carried out is an accounting information system design that is able to support the operational needs of Cooperative. The superiority of the resulting system is that there is a treasurer who specifically manages the finances of the Cooperative so that the process of recording financial reporting runs effectively and efficiently which has been designed according to the needs of Cooperative

Web service is actually a collection of functions and methods contained on a server that can be called by the client remotely, then to call those methods we are free to use applications that will be created with any programming language that run on any platform. The existence of web service technology can bridge the technological differences of each source. The purpose of this system design is to build a mediation system that can integrate different information systems platforms, databases and functions, so that can communicate between systems. Software development methods used include three main parts of the method of analysis, design and literature study. Methods of analysis include the collection of data using samples, learning on existing systems, and analysis of the results of interviews aimed at the parties concerned. Design method using Unified Modeling Language (UML) approach. The result is a system-based mediation system design using the SOAP (Simple Object Access Protocol) protocol. Index Terms— Web Service, Mediation

As a main handling device the portal crane is widely used in port, railroad, etc.The crane handling procedure is mainly carried out through its combined-boom system luffing or swing .In general, in order to reduce drive power and improve the operational performance, the luffing trajectory should meet the design requirement. At the same time, structure stress should be secured in the whole process of handling the cargo. Recently, to deal with more heaver and further cargo, the portal crane is becoming more large-scale. So that the large-scale components such as jib elastic deformation effect on large displacement motion cannot be ignored longer. In addition to the structure high speed motion in the process of handling also make the structure dynamic behaviors spending more obvious specially in the condition of luffing combined with swing. However, the problem for this dynamic behavior brings about to physical design sometimes has no method to solve according to the conventional analysis algorithm and dynamics method. To reduce the deviation caused by the common analysis, design and analysis method based on the multibody is put forward in this thesis. According to the method, the result on the luffing trajectory and stress-time history are analyzed easily. So that it ensure the efficiency and increase the accuracy of the initial design according to the conventional design and analysis method.

A lot of problems often occur in production monitoring, because companies still rely on manual processing system. Therefore, this research is objected to facilitate the monitoring of production processes, to minimize human error in the production process, to make automatic the process of existing transactions, toclarify the duties of production monitoring of an acrylic manufacturer. The research methodology used is literature study by reviewing previous theories and studies related to the topic. Furthermore, analysis method by studying the running system of the company as well as evaluating the distributed questionnaire and analyzing the results. And finally is the design method using the Object-Oriented with UML. The research resulted in an application design of a production monitoring system. The result of this design has been implemented into the selected DBMS. The new monitoring system helps monitoring the production system properly, as well as makes the transaction run systematically. The each production process starting from project orders, sample orders, sales orders, material releases, production, assembly, and delivery order within can be monitored quickly and properly. The activity reports can also be generated more systematically and comprehensibly.
