Information system Analysis is very important to do to produce easy, effective, efficient, and proper use system for the user. This research is meant to design and apply information system analysis model with the concept of Human Computer Interaction (HCI), Jacob Nielsen’s usability criteria which are learnability, efficiency, memorability, errors and satisfaction. The model of information system analysis Human Computer Interaction (HCI) with five usability criteria can be used as a standard to analyze how far Human Computer Interaction can be applied into the system so that every weakness will be known and system maintenance can be performed. The application Human Computer Interaction model in analysis of Sistem Administrasi Sekolah (SAS) produce a conclusion that only half of Human Computer Interaction concept applied into SAS Dikmenti DKI Jakarta. SAS is easy to be learned and to remember but SAS is not efficient and not yet have the ability to cope the mistake well. Users are satisfied enough with the result achieved through SAS but the facility provided by SAS is considered not enough to accommodate the need of the users.

Encryption is a solutions to secure the information transmitted through the medium of communication that can not be intercepted by unauthorized parties. This study implemented two algorithms i.e. RC4 and GGHN (8.8) in video conference. This study compared the speed  of  both  encryption  and  decryption  of  the  encryption  algorithm,  and  perform  measurements  of  bandwidth .  From  the  results  of measurements of the speed can be concluded that the RC4 algorithm is 1.53 times and 1.34 times faster than GGHN(8,8) for encryption and  decryption  audio  data.  The  encryption  and  decryption  video  data  RC4  are  1.44  times  and  1.09  times  faster  than  GHN(8,8). Bandwidth  usage  for  video  conferencing  without  encryption  and  bandwidth  usage  on  a  video  conference  with  RC4  encryption  and GGHN (8.8) is the same.Keywords: Video Conference; RC4; GGHN(8,8); Real Time Protocol.

The research on image identification has been conducted to identify the type of beef. The research is aimed to compare the performance of  artificial  neural  network  of  backpropagation  and  general  regression  neural  network  model  in  identifying  the  type  of  meat.  Image management is processed by counting R, G and B value in every meat image, and normalization process is then carried out by obtaining R, G, and B index value which is then converted from RGB model to HSI model to obtain the value of hue, saturation and intensity. The resulting value of image processing will be used as input parameter of training and validation programs. The performance of  G RNN model is more accurate than the backpropagation with accuracy ratio by 51%.Keyword: Identification; Backpropagation; GRNN

This research aim to developed an inventory information system which integrated convensional data records with an analysis system based on inventory theories to answer questions about supplying stock, i.e. the latest inventory counts, prediction of future sales, when to order supply and how much to order these supply. In this research, purchasing and selling data records that usually seperated, had been integrated into an inventory database so up to date inventory list can be shown at demand. Furthermore, with data of past time sales, system will predict future sales using Least Square Linear Regretion method and Moving Average method. Inventory analysis will determine the Economic Order Quantity and Reorder Cycles for single item and multi item. An early warning also will notify user when an item reach the reorder point. This information system software that can be used to answer similar inventory problems in retail or warehouse company. As addition, research shown that sales with increasing/decreasing pattern had a more accurate prediction using Linear Regretion, while Moving Averages are better for stable sales. Research also shown multi items order collectively for the same supplyer more cost beneficial rather than single item orders.

Geographic  information  system  useful  to the  government's  classifications  to  determine  the priority of the  welfare of  society.  While  the criteria  used  are  6  criteria  and  14  sub  criteria  and  their  implementation  is  still  done  by  manual.  The  method  used  in  the  study  "The implementation  of  Geographic  Information  Systems  and  AHP  for  Village-Based  Economic  Classification  Society"  is  the  method  ofAnalytical  Hierarchy  Process  (AHP)  in  which  the  classification  process  conducted  by  the  preparation  of  the  hierarchy,  giving  the comparative value of each criterion to determine the value of the criteria. As for the mapping process using Quantumgis and MSAW 3.0. Quantumgis  and  MSAW  3.0  is used  because  both applications  are  open source applications  that  can  be used  without having  to pay  fortheir use. The results of the application system that can be used to make the process of classification societies where the determination ofcriteria  and  sub  criteria  can  be changed  in accordance  with  the  desired  indicator.  Results  included  as  data  calculation  and  classificationwith the City district map can be made a map of economic classification society in City districtKeywords: Geographic information systems; AHP; Economic; Classification society.

Development of information technologies is often misused by an organization or a person to take criminal acts, such as the ability to steal and modify information in the data distribution for evil criminal purpose. The Rural Bank of Boyolali is conducting online financial transactions rather intensively, thus it requiring a security system on the distribution of data and credit transactions for their customer among branches offices to head office. The purpose of this study was to build a security system in credit transactions in Rural Bank of Boyolali for their customers among branches offices to head office. One way in protecting data distribution was used XML encryption and XML signature. The application of encryption technique in XML and digital signature in XML by using web service by using the AES (Advanced Encryption Standard) and RSA (Rivest-Shamir-Adleman) algorithms. This study was resulted the SOAP (Simple Object Access Protocol) message security system, with XML and WSDL (Web Services Description Language), over HTTP (Hypertext Transfer Protocol) to protect the customers’ credit transactions from intruders. Analysis of examination indicated that the data size (bytes) transferred as results of uncompressed XML encryption were larger than compressed XML Encryption, which leads to significant changes between the data transferred that was the processing time of the compressed data was faster than uncompressed XML encryption.
