<![CDATA[In a large corporation with multiple network devices, a network operator often has to manually configure each device. However, there are some requirements to re-organize devices becomes more flexible in order to respond to challenges such as restricting host and port (services) access.SDN or Software Defined Network is believed by some people to be one solution to answer the above challenges. In this study, some of the above problems will be answered using the concept of SDN. If there is a point of management, it will be possible to change network behavior and / or other configurations, and make other changes dynamically or automatically (programmed), especially in policy changes. In this exploration, OpenWRT is embedded in network devices so it is possible to be controlled. To facilitate the programming of the network, then built web services that are equipped with security authorization.The results of this exploration show that the concept of Software Defined Networking can answer the above problems, with relatively low cost.]]>

<![CDATA[This thesis’ goal is to let computer recognize Javanese letters. Before a computer is able to recognize Javanese letters, segmentation and feature extraction process is needed. After the features of Java letters that have been segmented obtained, then the features will be processed using computer learning method so that the computer can recognize the letters.Input is in the form of .CSV file that contains features of the Javanese document image that had previously segmented. Output text is a text file that contains unicode representation letter from Java font and a .CSV file that contains the test and data classification results. This application is created with C# programming language and Microsoft Visual Studio 2013 IDE.As for the process that is done is as follows: prepare the .CSV file resulting from the extraction of features to be used as learning materials or trainer for computer learning network. After the trainer file ready, then the network will be trained. After the training is complete, the network can receive other data input, and then classify it according to what has been learned.Probabilistic neural network and ID3 used as computer learning methods, which after data testing, it is found that PNN give higher accuracy result than ID3.]]>

<![CDATA[Rendering is the process by the end of the whole process of modeling or computer animation to change the form of three-dimensional objects into two dimensions. One popular method of rendering known today is ray tracing. Ray tracing is a technique for generating an image by tracing the path of light through pixels in the image.Ray tracing method is able to produce realistic images because it is calculating lighting effects such as ambient, diffuse and specular. Reflection and refraction of light is also calculated in ray tracing. In addition, ray tracing method is divided into two kinds, known as the tracing rays from the eye (backward ray tracing) and tracing rays from the light source (forward ray tracing).Caustic effect produced by emitting light in a transparent object. Refracted light will gather in an area so that the area will appear brighter than the surrounding areas. In previous studies, the effect of caustic applied to the primitive object, where the light checks done once per object. In this study, the object used is mesh. Checking the light will be performed on each triangle in the mesh.Results showed the greater refractive index, the more caustic effect gathered in certain areas of the body bare round, but spread on a flat and taper grounded object. The increase in the complexity of the mesh will increase linearly time. Comparison with other software shows the difference in the form of caustic effects and rendering time.]]>

<![CDATA[PT Trias Sentosa was founded in 1979. The company is dealing with manufacturing and production of plastics, During the last year to date, PT. Trias Sentosa Tbk has used a security system that is highly controlled and has been tested kelayakanya communication between each warehouse to a central server. However, sometimes the data from BOPPET that go into servers sometimes experience an error or what is often called "bugs" this causes their data and data terduplikat less valid, but each day PT Trias itself made of plastic with a large number. Therefore, the Information Systems Audit and ISO (International Organization for Standardization) to a solution to measure whether the security of application systems that exist within the company in accordance with the standards that have been internationally recognized that IT governance contained in the COBIT (Control Objectives for Information and Related Technology). COBIT is a framework for information technology published by ISACA (Information Systems Audit and Control Association) and is used because it has a high level of complexity and coverage. As well, in this analysis, the domain used is based on COBIT Deliver and Support. Then from that domain, the discussion is limited to the level DS5 (Ensure Security Systems). And to ISO itself is limited by ISO 27002 (Information Security Management System.)]]>

<![CDATA[Stock opname merupakan penghitungan dan penyesuaian stok barang dan aset yang dimiliki oleh toko atau perusahaan di gudang atau etalase dengan data stok yang terdapat pada database sistem perusahaan. Selama stock opname dilakukan, kegiatan masuk dan keluarnya barang tidak dapat dilakukan. Hal ini menyebabkan perusahaan tidak teratur dalam melakukan stock opname. Selain itu kesalahan pencatatan yang dilakukan oleh pegawai juga rawan terjadi jika barang yang dicatat cukup banyak.Berdasarkan latar belakang masalah tersebut, maka dibuatlah aplikasi untuk melakukan pencatatan stock dengan menggunakan barcode. Aplikasi ini dibuat pada mobile device berbasis Android karena selain kegunaannya sebagai telepon genggam, mobile device juga memiliki fasilitas yang modern seperti kamera dan koneksi internet menggunakan wifi sehingga dapat pula dijadikan sebagai barcode reader yang dapat terhubung dengan server perusahaan.Hasil dari aplikasi yang telah dibuat antara lain, dapat melakukan download data stock barang dan aset dari server tergantung otorisasi, dapat memindai barcode dengan menggunakan kamera yang terdapat pada mobile device untuk melakukan pencataan barang, dapat melakukan pencatatan jumlah stok barang dan aset pada periode tertentu,dan terdapat laporan pencatatan stock barang dan aset pada periode tertentu]]>

<![CDATA[Taking pictures has become common thing to do for capturing certain places. The process of taking and storing pictures that quite easy affecting the number of pictures taken and not well arranged. This results in difficulty finding desired image with ease. Several applications have been created to facilitate the process of organizing images. Generally, the applications use metadata and geotagging of the images. However, metadata and geotagging cannot be seen by naked eye in the picture. So in this paper the application that classifies images based on object which appear in the images will be made. To make this application, SIFT feature from image will be used. Additionally RANSAC method will be used to improve the accuracy of matching SIFT features. A database is also set up to avoid ambiguity in matching SIFT features and speed up the process of grouping.Based on the conditions at the time of testing the average value of success rate of classification with SIFT and RANSAC method can reach 72.5%. In addition it was found that SIFT features are vulnerable to the view point, tilt, non-linear illumination and lighting effects due to texture objects. Thus providing patterns that can cover the changes on SIFT features is necessary. In addition, the image preprocessing is needed to eliminate the possibility of ambiguity pattern matching on SIFT features due to background, texture, and patterns which contained in images.]]>
