Authenticity of access in very information are very important in the current era of Internet-based technology, there are many ways to secure information from irresponsible parties with various security attacks, some of technique can use for defend attack from irresponsible parties are using steganography, cryptography or also use digital signatures. Digital signatures could be one of solution where the authenticity of the message will be verified to prove that the received message is the original message without any change, Ong-Schnorr-Shamir is the algorithm are used in this research and the experiment are perform on the digital signature scheme and the hidden channel scheme.

Along the development of information technology systems among the public at large, also develops information systems to facilitate the public to access and search for information in the form of a website. Electronic Procurement Service (LPSE) Palembang is a business unit set up to organize the service system of government procurement of goods or services electronically. And to allow companies or providers that want to follow the procurement of goods or services, LPSE providing a website that can be accessed from anywhere so the company or provider to follow the procurement of goods or services without having to come to the office LPSE. In the management of its website, LPSE Palembang has its own web server so that the need to consider the existing security system on the web server. Web servers often become the target of attacks by an attacker. This study is set to test the security system of the web server to find out if a web server is secure or not of the crime committed by an attacker. This research involves penetration testing with multiple applications. The results show some holes and suggestions.

Development of information technology, especially in the field of computer network allows the exchange of information faster and more complex and the data that is exchanged can vary. Security of data on communication in the network is a major thing. Secure socket layer (SSL) is the solution to the problem, but further research on the security of the SSL protocol transactions should be done to determine the extent of SSL can secure the data on the network. When the computer sends data across the network, the data is transmitted in packets. Sniffing is a technique of monitoring of every packet traversing the network. Security threat presented by sniffers is their ability to capture all incoming and outgoing packets through the network, which includes the passwords, usernames and other sensitive issues. Packet sniffer captures the data addressed to other devices, which will then be stored for later analysis later. Sniffing can also be used by system administrators to monitor the network and solve problems in the network.

Decision support systems (DSS) can be used to help settlement issues or decisions that are semi-structured or structured. The method used is Fuzzy Tsukamoto. PT Triprima Finance is a company engaged in the service sector lending with collateral in the form of Motor Vehicle Owner Book or car (reg). PT. Triprima Finance should consider borrowing from its customers with the consent of the head manager. Such approval requires a long time because they have to pass through many stages of the reporting procedure. Decision-making activities at PT Triprima Finance carried out by the analysis process manually. To help overcome these problems, the need for completion method in accuracy and speed of decision making feasibility of lending. To overcome this need to develop a new system that is a decision support system Tsukamoto fuzzy method. is expected to facilitate kaposko to determine the decisions to be taken.

Search engines are a combination of hardware and computer software supplied by a particular company through the website which has been determined. Search engines collect information from the web through bots or web crawlers that crawls the web periodically. The process of retrieval of information from existing websites is called "web scraping." Web scraping is a technique of extracting information from websites. Web scraping is closely related to Web indexing, as for how to develop a web scraping technique that is by first studying the program makers HTML document from the website will be taken to the information in the HTML tag flanking the aim is for information collected after the program makers learn navigation techniques on the website information will be taken to a web application mimicked the scraping that we will create. It should also be noted that the implementation of this writing only scraping involves a free search engine such as: portal garuda, Indonesian scientific journal databases (ISJD), google scholar.

BP3TKI Palembang is the government agencies that coordinate, execute and selection of prospective migrants registration and placement. To simplify the existing procedures and improve decision-making is necessary to build a decision support system (DSS) to determine eligibility for employment abroad by applying Fuzzy Multiple Attribute Decision Making (FMADM), using the linear sequential systems development methods. The system is built using Microsoft Visual Basic. Net 2010 and SQL Server 2008 database. The design of the system using use case diagrams and class diagrams to identify the needs of users and systems as well as systems implementation guidelines. This Decision Support System able to rank and produce the prospective migrants, making it easier for parties to take decision BP3TKI the workers who will be working out of the country.

Scientific journals are very important in recording the finding from researchers around the world. The recent media to disseminate scientific journals is PDF. On scheme to find the scientific journals over the internet is via metadata. Metadata stores information about article summary. Embedding metadata into PDF of scientific article will grant the consistency of metadata readness. Harvesting the metadata from scientific journal is very interesting field at the moment. This paper will discuss about scientific journal metadata harvesters involving XMP.
