Abstract

ABSTRACTTechnology developed in order to facilitate human work that would not be done manually, with the presence of the latest technologies that it is not a work of man may not be done quickly, accurately, and save time. One was for the manufacture of palm data processing applications that provide an overview to the public that it is feasible to plant palm oil or not to do, based on existing data and then recycled into Decision Support Systems. To process these data using the Internal Rate Of Return (IRR) as a method to make decisions based on data that have been processed. In this study processed data is the data of a group of Palm Jl. Salak Linga Kuamang Bungo Jambi. From the results of the data managed by the farmer group Palm block 22, Jalan Salak, Linga Kuamang, with interpolation of 30% per year, with a capital of USD 888,253,000.00 and generate income of Rp 2,063,387,050.00 in if using the Internal rate of Return produce interpolation (I) of 30, 113%. Since IRR> I, then it is worth to continue.

Abstract

The development of information technology is increasing at this time, certainly makes it easy for users of the technology itself. One of them in transferring files in a distributed manner, there are many types of files that make it difficult admin in selecting and classifying the file and then will be distributed to each - its own servers. By creating a new system that will facilitate Clustering distributed file an admin in file transfer without having to select the files to be distributed, because the system will automatically read from the file types that will be distributed on its own servers - each.

Abstract

Cloud computing, one form of information technologies are widely used in the field of computer networks or the Internet. Cloud computing consists of computer hardware, computer networking devices, and computer software, the cloud computing there are three services provided include (SaaS) Software as a Service (PaaS) Platform as a Service, and (IaaS) Infrastructure as a Service. Application cloud computing services in the wake of this system is a service-based data storage infrastructure as a service by using android smartphone as a storage medium, which utilizes FTP Server which is already available on the smartphone. This certainly supports the easy storage of data that utilize various types of internal and external storage on smartphones that serves as a storage server. In addition to the functions of storage available, this service can accommodate streaming function .mp3 file type. Implementation result of the system can be implemented on a local network using a wireless LAN. In addition, the results of user testing using Likert method shows the application can run and function properly

Abstract

Samosir regency is a from North Sumatera province which dominantly people is live on agriculture. The most of the farmers using autodidact learning to determining the types of plants that will be process the appropriate with their land, where farmers just learn from their experiences and exchange opinion with another farmers. Based of the problem, the system will be built by Analytical Hierarchy Process (AHP) with Genetic Algorithm. The result of the testing from method Analytical Hierarchy Process (AHP) obtained result with consistency ratio values < 0,1, which is -0,5936 while the result of the testing from Genetic Algorithm obtained value of the fitness is 157,25. Based on the test results, it can be concluded that the method Analytical Hierarchy Process (AHP) obtained the result more consistent with the value of consistency ratio should be < 0,1, so it will be easier to making decision, while on the analysis of Genetic Algorithm, obtained result are probabilistic as always having random process, so that decision making can not be consistent. So, Decision Support System to determination of plants based by contents of soil which are good and suitable is method Analytical Hierarchy Process (AHP).

Abstract

In an era like today's global, Internet-based information system security is a must to be considered, because of the public nature of the internet network and global is not safe. Basically the threat is coming from someone who wishes mempuyai gain illegal access to a computer network. Whenever there is a threat encountered on the server such as port scanning, the attacker IP addresses will be captured. Next will be used method Automatic Event Detection And Activity Monitoring (ADAM) to process security. ADAM will carry out retaliatory attacks in the form of a computer virus that was sent to the attacker. For this reason when a computer network is attacked by the intruder, then ADAM server will detect this type of attack is done, then asked for help from another server to strike back. Security server by applying the method ADAM able to do the blocking of port scanning the attacker did not end there ADAM will then send the file is a virus automatically. In terms of time efficiency, the method of securing the ADAM automatically faster than if all phases of the security is done manually. ADAM test non-adaptive systems this takes 4.4 minutes, while the time taken by the ADAM system to immobilize the attacker system only 1 minute 03:59 seconds, so the method ADAM work faster. Traffic normal state (RX 232B, 144B TX), but when encountered in the form of port scanning attacks become 21.46Kib TX RX 25.83Kib, and after working as RX 219B ADAM TX127B, resulting in a significant reduction in traffic.

Abstract

Self defenseis a system for defending selfwhich is used to defeat the opponent quickly and without spending a lot of energy. Self defense training is also very needed for pilots and flight attendants, for example to confront the hijacking of commercial flight.Self defense can be trained through the medium of interactive multimedia with 3D animation content. This interactive multimedia was built  by using adobe flash professional software, and 3D content using Lightwave 3D software. The result gets from trials to 30 respondents is this learning simulation is used because it is worth more than 50% of users give good response to simulation as a whole.

Abstract

Technological developments in the field of computers getting faster requires the ability of each person to be able to follow the progress of computer development. Computer vision applications is an application that allows the computer to have the ability to be able to capture and understand the data, such as image and make decisions based on the data from the real object movement that was in front of the webcam and then the data obtained is processed in accordance with user needs. Digital image of a real object is captured by a webcam can be done in various ways making objects. In this research, object retrieval by utilizing activity in this object is that caught on webcam pen is through the form and motion of objects. Once an object is detected then the object is to move the cursor on a computer. To be able to perform image processing, this application uses OpenCV components. Meanwhile, to be able to perform tracking of the cursor object using optical flow method. Cursor moves when the pen has a rectangular sides and parallel to the pen position frame of grabber.
