Labor productivity is an integrated interaction between production employees by way of an agency. To the Staff motivation is important because the quality and productivity of labor will usually aroused when their impulses work, productivity assessment can be predicted by using the concept of Artificial Neural Network (ANN) where the encouragement of this work can be influenced by several factors such as ability, attitudes, behaviors that will serve as the input of neural networks to produce the level of productivity in the form of good or bad value. Keywords: employee productivity, artificial neural network

In the community of information technology users often occur several crimes either consciously or unconsciously, intentionally or unintentionally done. Way to secure data in the form of digital images can use cryptographic technique; cryptography is one of the techniques used to enhance the security aspect of information. Cryptography is the study of science and art to keep a message or data information so that the data is safe. Cryptographic support the needs of the two aspects of information security, namely secrecy (protection of the confidentiality of data information) and authenticity (protection against counterfeiting and alteration of information that is undesirable). Along with the development of computer technology, the world of information technology requires a stronger cryptographic algorithm and secure. Currently, AES / Rijndael (Advanced Encryption Standard) is used as the newest standard cryptographic algorithms. AES / Rijndael replace the DES (Data Encryption Standard), which in 2002 was over its service life. DES is also considered to be no longer able to answer the challenges of the development of communication technology very quickly. AES / Rijndael itself is a cryptographic algorithm using the algorithm AES / Rijndael to encrypt and decrypt the data block along with a 128-bit key length of 128 bits, 192 bits, or 256 bits. Blowfish is an algorithm that uses a block size of 64 bits of data along with the key length of 448 bits. To produce a digital image pixel values randomly needed a method transpormasi Discrete Wavelet (DWT) to generate a random pixel values before the encryption process. So from this comparison produces research in the form of computation time (Computation Time), average shape error (Mean Squared Error), Total changes in pixel values, Level Number of Pixel Change (NPCR), peak signal to noise ratio (PSNR (dB)). Keywords: Digital imagery, Rijndeal, blowfish, Computation Time, Mean Squared Error, Number of Changing Pixel Rate, Peak signal to Noise Ratio

Internet Financial Reporting (IFR) becomes an important trend in line with the development of internet technology. Companies can store financial information via the Internet to reach a wider audience and worldwide, faster and cheaper. This study sought to examine the practice of Internet Financial Reporting (IFR) and analyze the factors that influence it. Samples were companies that belong to the calculation of LQ-45 in 2012. The samples were taken by purposive sampling, in order to obtain adequate samples for the study were 39 Company LQ-45. The technique of analysis using multiple linear regression analysis. While the hypothesis used to test the results of the partial (t test) and simultaneous (F test). The results of this study indicate that the factor profitability and firm size have a significant effect on the practice of Internet Financial Reporting (IFR). However, other factors, such as: public ownership, leverage and industry groups did not significantly affect the practice of Internet Financial Reporting (IFR). Keywords: Profitability, Company Size, Public Shareholding, Leverage, Industrial Group

Cloud Computing is a trend that includes several categories of services, all offered in the form of an Internet service with a model pay for what is used by the user (pay as you go). Software as a Service (SaaS) is one in this category, in addition to Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). SaaS is the most mature category of Cloud Service, as evolved from the model application service-provider. Hospital as an institution that provides service every day of non-stop for 24 hours, began requiring the application of Cloud Computing to save operating costs of data processing, improve agility, but still can involve a lot of users. Therefore we need an appropriate architecture to meet the expectations of the Hospital. SaaS architecture in hospital services will contribute to the Data Architecture, Application Architecture and Technical Architecture will even contribute also to the Organizational Architecture. Keywords: Cloud Computing, Software as a Service
