| Abstrak | : | There is not any protection at all in HTML documents, so user just needs to download the intended documents and change them. This is the reason why the security and originality of the data in the World Wide Web should be taken into account. To maintain the validity of HTML document, it needs a system that can detect the originality of a document. The process being done in this paper is validating HTML document It means those HTML documents are given a sign proving its originality, for example digital signature. The originality sign depends on the input, in this case is HTML text document. If a document is valid then the data is still like the original no change at all. If the data is not valid, the data is not original anymore or there has been any change From the stages in this research, it is proven that HTML text document validation can be done with MD5 method and protection using MDS is very hard to break even though with brute force This proves that MDS security is one of the best. |

| Abstrak | : | The impact of non ideal gas on termionic generator is reviewed in this research. Many investigations assume ideal gas in analysis of thermionic generator although the systems investigated are distributed with respect to energy. In order to conduct this work, there are plenty of non ideal gas correlations. However, the current research focuses on level of electron gas compressibility to observe the influence on termionic generator efficiency. As a preliminary study, results show that increment of compressibility of electron gas will increases efficiency. Higher gas density means higher excited electrons and from gas relation, increase compressibility. It is also concluded that slope of efficiency is more sluggish with higher compressibility and grow asymptotically with increment of B. Meanwhile, the direction of further study is also presented. |

| Abstrak | : | This paper presents the study of acoustic wave propagations in two dimensional domains with unstructured nodal high-order Discontinuous Galerkin (DG) method. The DG method employs triangular elements and uses piecewise high-order Koornwinder Dubiner polynomials for spatial discretization and low storage fourth order Runge Kutta for time integrations Fluxes are calculated by using upwind fluxes. After demonstrating the exponential convergence of the DG method, the acoustic wave propagations in complex domains are studied. |

| Abstrak | : | The minimum agitation speed as a parameter must be known to achieve complete mixing with minimum of consume of energy. Goal of the research is to experimentally investigate the minimum agitation speed with some affecting variables. Measurements of the agitation speed in mixer settler extractor (MSE) as functions of the impeller diameter and number of impellers are reported. The Heavy Gas Oil (HGO)-DiEthylene Glycol (DEG) with the IGO dispersed phase was studied. Relation between the minimum agitation speed with the some affecting variables will be explained |

| Abstrak | : | A big portion of manufacturing cost in supply chain systems is spent on logistics cost. An approach that could be applied to reduce logistics cost is optimizing distribution channel Dynamic market, frequent and low volume orders, and shorten delivery dead line characterize current supply chain system. This paper describes the application of distribution strategies to reduce logistics cost as a response to the up-to-date supply chain characteristics. Logistics data from PT Fonterra Brands Indonesia are used as the case. Distribution strategies being analyzed are warehousing, crossdocking, and direct shipment. The objectives of reducing logistics cost are to achieve lower production cost and enhance customer satisfaction. Customer satisfaction is shown by their willingness to adopt certam distribution strategy. Modification of the existing distribution strategy as a response to actual market characteristics is also presented |

| Abstrak | : | Communication by using physical media is the communication of channel transmission with using wire, such as coaxial wire, fiber oftic, and rectangular wave guide. Otherwise, non physical media is the air, which is used as a channel transmission and it will be more effective and economic than physical media. If the air media is used as channel transmission, so we need new device which can change electric light wave to induction electromagnetic wave and it is on the contrary In this study, antenna is a device, so the we claim that the title of the working paper is the The double ring base of antenna base which is spreading emission through a corner emission zero degree maximum |

| Abstrak | : | Data Structure is a compulsory semester subject in the Department of Informatics, Atma Jaya University, Yogyakarta, Indonesia. There are 121 students enrolled in this subject, all of whom need to be allocated to classes. This fact raises three questions. Firstly, what is the appropriate number of classes? Secondly, how do we allocate those students into classes? Thirdly, which student belongs to which class? The answer to the second and the third questions for a given number of classes was formulated in (Susanto and Ernawati, 2006) by employing the Fuzzy Clustering concept As a development to (Susanto and Ernawati, 2006) and (Susanto and Ernawati. 2003) this research tries to answer the first question by emploving the Parntion Coefficient and Exponential Separation (PCAES) Index. |

| Abstrak | : | The SMS utility is developed so that the users could easily carry out the sending and acceptance of the SMS through the computer. This research is done by the arranging of the source code to develop the utility that can be used for the sending and acceptance of the SMS through the computer. The utility is also supplemented with means of reading memory of the mobile phone. The utility is designed to be able to work in the Linux operating system. The source code is written in the C language and is compiled using GNU C Several C libraries are used to support mobile phone connection with the computer. For mobile phone connection with the computer is used infra-red port. The results of this research show that the SMS utility can be used for the sending and acceptance of the SMS through the computer The SMS utility still cannot read automatically the SMS that enters into mobile phone. |

| Abstrak | : | Software developments often have many risks, such as development failures, cost-overruns, and schedule overruns. Those factors have to be minimize using risk management, and one of risk management methods is Just-In-Time (JIT). The concept of JIT is managing costs. schedules and software functionalities. JIT talks about risk quality of those factors, and asualy people have difficulty to fix or minimize risks by thinking the quality area. Then Karolak (1999) was developed Software Engineering Risk Model (SERIM) based on JIT method to analyze riks and give quantity results SERIM uses risk metrics that contains many question to be answered by management and then solves problems by making conchtion of results SERIM and JIT are used in this analysis to give conclusions on simulation case. The case is about software developer that have internal organizations and software documentations problems, and these problems usualy make cost-overruns and schedule-overruns Target of analysis are getting risk quantity, making conclusions about how to minimize risk by using risk management. |

| Abstrak | : | Many organizations including bookstores have used Searching System in order to find some datas they need in the large databases. People search books based on the keywords they entered. Unfortunately not everybody knows exactly what do they look for, they just go to the bookstore but do not know what do they want. To help somebody like that, we will develop The Recommender Searching System (RS-System). RS-System gives someone a book recommendation based on taste similarity with other persons. This system uses collaborative based recommendation mechanism and applies clustering analysis technique. |
