Abstract

Streaming technology is currently experiencing a great progress. Faster internet more users streaming. Streaming services that exist today there are still weaknesses in both the upload speed, streaming speed and limited types of video extensions that can be played. To resolve these problems then made a video streaming service based local area network with a system of cloud computing that can work effectively in terms of upload speeds, streaming and variations in video formats. Video streaming application is classified as a service IaaS (Infrastructure as a Service Cloud) in cloud computing. On the use of streaming applications the user does not need to convert the video, with the purpose of uploading process can be faster and applications can play a variety of video formats.

Abstract

The camera on the smartphone was basically to take pictures or video with equivalent quality digital camera or video recorder. The camera on the smartphone lies in two different locations, first place the rear side and the second being in front. Drone Syma x8hg who used to fly a smartphone for the shooting process is controlled from the laptop software, maximum range 80 meters from the drones by remote control. Software on Android devices and laptops must first diinstalisasi so both devices can be connected to the web server of the provider to process images from a drone Syma x8hg, the two devices must have a network connection provider respectively. Results from testing the smartphone camera carried by a flying drone can be controlled for filming with the distance is affected by the strength of the signal from the service providers internet connection, while the height is limited by the strength of the signal between the drone with remote control.

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

Distributed system is a computer networking technology which can be hardware or software. In hardware distributed system by a collection of computers that are heterogeneous, being in the software system is distributed in the form of software that connects two applications in the form of client and server side. TSC method is a method that already existed before, which can be used increase the ranking o f a blog. Implementation distributed system for TSC using landing page as the intermediary. Landing page serves as a liaison between web applications or blogs are listed as a member to raise the ranking of a database on the application server side. When someone does click on landing page seoindonesia, will open a blog or other web members. Landing page so it can be used as a way to count the number of visitors to a blog or website, which in turn can increase the number o f page visits and 1 with 1 clickbutton seoindonesia for test in histats.com.

Abstract

The introduction of color to children under three years of age is done by providing and explaining objects favored by children, such as toys and food, which have certain colors so that children recognize colors at that age. Unlike adults, how to introduce color in children does require a different way, in addition to the objects and food, in this study the introduction of color in children is done by using the software that is installed on the smartphone using the image to speech. This method is expected to be more easily carried out and the results are expected to be maximum because of equipment smartphones today the price is very affordable and are often used by children ages two until three years old to play games.

Abstract

Wi-Fi waves are commonly used as an intermediary in the communication relationships in the wireless network. However, the use o f Wi-Fi waves can be used in addition to getting the relationship in the network, the user is also able to detect and identify other devices by using Wi-Fi waves. Ad-hoc network is a network that can be built independently by the computer with the Microsoft Windows operating system, to enable ad-hoc device has to have an identity that is SSID, the SSID is then activate the device can be detected by other devices. Activation is done ad-hoc by the netsh command is a shell command in the Windows 7 operating system. An ID must be unique for each device as there is no dual identity, to maximize the identification process. Utilizing MAC address as an identity is used, allowing the device to be uniquely identified. In addition to the MAC address is added to the device profile in the identity o f the device for easier identification. Sapa application users can identify the device is detected, and recognize it as a co-owned devices. Scheme which is the concept o f the algorithm Sapa. Sapa application allows device activation or notebook PC with the Windows 7 operating system to be detected and detected by other devices with the Windows 7 operating system and applications are also active Sapa. Communication is established indirect communication that occurs in a single direction. Detection range can be done up to 77 meters distance.

Abstract

MPLS (Multi Protocol Label Switching) technology has been developed and mostly used by the service provider on their main network. Data packets which forwarded from one router to another router can also use VPN (Virtual Private Network) technology. VPNs were developed in the field of computer networks now have many variants, such as MPLS VPN and VPN which connects between computers or a LAN through a public network is the internet. The purpose of this final task is build a lab scale VPN network with MPLS technology use Mikrotik router RB 750GL and create a VPN connection to the STTA campus network passing the public internet. Then do a comparative analysis of the time required and the speed of transfer on both the network. The results of a comparative analysis between MPLS and VPN with the same file capacity, it appears that the MPLS network is faster in time speed and transfer speed

Abstract

File synchronization is the process of homogenization or adjustment between one file at a location with other files in the event that a change to be used up and running in a system. File synchronization is generally a process of data exchange in order to have the same amount of data. To maintain the confidentiality of the data necessary to maintain services for data security.            The use of cryptographic AES (Advanced Encryption Standard) to encrypt the file and combined with the administrator as an authentication key in making additions or changes to the file is a security system that can be applied to synchronize the files so that data confidentiality will be maintained.            The results of the implementation of file synchronization application by applying the AES cryptography and key administrators who carried on the local network and the Internet as a service application data synchronization between the user and the service back-up data as manual handling if storage was damaged and can avoid the theft of data from a file synchronized.
