Abstract

Selection of providers of goods and services is a routine work carried out by the Ministry of Public Works Directorate General of Water Resources (DPU DirJen SDA) Yogyakarta as auctioneer project procurement. The auction process conducted by 2 steps that must be passed by each participant selection, namely the pre-selection andselection process. Pre-selection stage takes a long time from the announcement of the project which will be auctioned to the technical bid evaluation assessment of participant selection document roadmap participants. The next stage of the selection process, this process will not work if the previous stage of the selection of participants who did not pass the next phase still could not accept the results of the selection committee on the assessment of the value of the technical evaluation of bids that have been made by the participant selection, because the rule is no objection period provided to participants if the selection can not accept the results of the assessment selection committee. The selection process will run to the next stage after the selection of participants receiving the results of the assessment of the selection committee and given objection period had expired. Based on the background of the existing problems can be formulated on how to make a design decision support system for the selection of providers of goods and services in DPU DirJen SDAYogyakarta. The decision support system aims to implement a decision support system for the selection of goods and services providers to the selection committee in DPU DirJenSDA Yogyakarta. The system works based on the data input of the selection committee which will then be processed by the system based on the required criteria. The data has been processed the system will be displayed and ranked by graphs of each participant selection. From these results we can conclude the committee which participantsprocurement of goods and services providers are entitled to handle the project.

Abstract

The development of internet technology ensures the availabilities of information anywhere and anytime. Internet users can access the required information via the internet very easy, that is no exception for students. However, if the availability of the information is not managed properly can cause some problems which can arise includeaccessing sites that are not related to education materials (such as porn sites, online gaming sites, etc.). Whereas sites like it usually requires a large bandwidth and are often infiltrated with warm or trojan. Also, often if the students want to access an internet, users must access to the site's server directly. This conditions will reduce access-speed. The university need a solution for it, so the construction of a Proxy Server can do. At Sahid University of Surakarta previously built systems using a proxy server with FreeBSD OS that has some weaknesses. Of weakness, the need to develop new systems to overcome the weaknesses encountered. The system will be constructed that is a proxy server using Fedora OS and Squid 2.6 as supporting software. Development of the new system is a proxy server, designed to block porn sites, online gaming sites, as well as speed up Internet access.The development of a proxy server system at Sahid University of Surakarta produce a faster internet access. Internet access management on the proxy server can block sites that do not relate to the world of education as well as network security firewalls and network control client. This system can also manage Internet access based on time and MAC Address of computer clients.

Abstract

Fractal geometry is branch of mathematics that studies the properties and behavior of fractal. In development fractal is branch of computer grpaphics. In this examination, fractal is discussi to develop computer graphics. The development does with literature and simulation based on former of each the curve. There are four fractal will be discussied in this examination, Koch curves, String Grammars, Julia and Mandelbrot Set. Koch curves are formed from line and angel rotation (α). For String Grammars the former of component is curve sentence, formulated with F : (axiom, F-string, f-string, X-string, Y-string, sudut). Mandelbrot and Julia Set are generation a set of complex number zn+1= z n2 + c. Where c belongs to the set of all complex numbers. Koch curve has a good curve if it has special angel (300, 450, 600) except 900. Example ofproduct from String Grammars are Dragon, Hilbert, Sierpinski, Island, Tree1, Tree2, and Tree3. Madelbrot and Julia Set has good curve if it has z coefficient among -2 up to 2 for Real and -2 up to 2 for the Imaginer and the number of iteration is bigger then 50, and the constant |c| is less then 1.
