Autolux Project is owned by DTT Multimedia B.V. Autolux is a platform for car lovers sharing their information about favorite or latest cars. The website was built in MODx (CMS framework) which considered being old and heavy by the company. With that very reason, a project to migrate the website from MODx into PhalconPHP (pure PHP framework) was started. Migrating website from MODx to PhalconPHP was a success, and to boost the website popularity, the first thing to do is to implement the SEO standards. Another demand by the company was for the website to be responsive and using OOP standarts. Responsive website can be reached by using the help of libraries. PhalconPHP already implemented OOP, thus the developer will follow the MVC pattern given and refine it by doing more separation of concerns. Later on, the developer also put more refinements on the website to boost the speed of page loading, support multilingual, and management system.

Richard John, Seng Hansun — Mon, 01 May 2017 00:00:00 +0000

Penelitian ini bertujuan untuk melakukan peramalan penjualan di masa mendatang beserta fitur-fitur aplikasi lainnya seperti kemampuan untuk menambahkan (insert), mengubah (edit), dan menghapus (delete) data produk dan ringkasan penjualan yang akan atau telah disimpan dalam suatu database untuk studi kasus perusahaan tertentu. Aplikasi yang dibangun menggunakan algoritma double exponential smoothing. Alasan pemanfaatan algoritma ini adalah nilai smoothing akan diperoleh tepat waktu sebelum data aktual saat data historis memiliki komponen trend. Oleh karena itu, untuk nilai smoothing tunggal, perlu ditambahkan nilai dari double smoothing untuk menyesuaikan trend tersebut. Metode yang dapat digunakan untuk memprediksi trend linear adalah metode dua parameter Holt. Pada metode Holt, nilainya bukan trend halus dari double smoothing secara langsung, melainkan penghalusan trend dilakukan dengan menggunakan parameter yang berbeda dengan yang digunakan untuk menghaluskan data aslinya. Hasil penelitian menunjukkan bahwa aplikasi yang dibangun memiliki persentase kesalahan sekitar 28,38%. Aplikasi yang dibangun juga mampu memenuhi fitur-fitur yang dikehendaki oleh user dalam pemrosesan produk dan rekapitulasi.

Lirik lagu merupakan suatu ungkapan perasaan seseorang terhadap sesuatu hal yang sudah dilihat, didengar maupun dialaminya sehingga tidak jarang emosi menjadi salah satu kriteria user dalam melakukan pencarian. Pencarian lirik melekat pada kategori yang tidak hanya terbatas berdasarkan genre atau judul lagu, namun juga melalui emosi dari lirik lagu yang diungkapkan. Agar dapat mencapai tujuan tersebut, diperlukan suatu sistem pengkategori yang mengenali lirik lagu secara otomatis dengan salah satu metode klasifikasi yaitu NaÃ¯ve Bayes. Faktor yang mendorong tingginya tingkat akurasi bukan hanya terletak pada metode klasifikasi saja, namun proses sebelum menuju tahap klasifikasi juga berpengaruh pada hasil yang didapatkan. Maka dari itu, penulis melakukan penelitian melalui beberapa tahap yaitu preprocessing berupa tokenisasi, stopword dan stemming, kemudian feature selection yang digunakan adalah TF-IDF dengan bantuan ISEAR karena mengandung 7 emosi dasar. Dari ketujuh emosi dasar tersebut, tiga diantaranya merupkan emosi yang akan digunakan dalam penelitian ini yaitu anger, sadness dan joy. Hasil dari penelitian ini menunjukkan dengan menggunakan ISEAR akurasi tertinggi terdapat pada feature set 60% dan 100% yaitu sebesar 82,2%. Perbedaan signifikan dihasilkan pada penggunaan ISEAR dengan akurasi rata-rata keseluruhan porsi featureset sebesar 77% sedangkan tanpa menggunakan ISEAR rata-rata akurasi sebesar 53%. Dokumen paling relevan untuk pengujian menggunakan ISEAR terdapat pada kategori angry dengan rata-rata f-measure sebesar 0.7267.

Febria Roosita Dwi — Mon, 01 Feb 2016 00:00:00 +0000

Muslim sometimes has trouble when they travel to a new place for find where the location of the halal food and mosque near their location is. Other things that Muslim will have difficulty when they travel in to a new place are find the Qibla direction, pray time in local time and the mosque location near their location. From that problem MLH (Muslim Little Helper) want to help them to solve their problem. The process is carried out as follows: The app get the user location, send the location to the YELP API server and muslimshalat.com API to get the location of halal food, and mosque (using YELP) and for find the direction of Qibla and the prayer schedule (by using muslimshalat.com API). After the system get the data, then it will show on the Map (using apple map inside the app) and put the data as marker. For the Qibla direction and prayer time, it will show in arrow image and listview. This app will be use Swift for the development language. The test result shows that the YELP API can be use only in USA, and internet play as the main rule in this app, because to create connection to the server to pull the data, the system need internet to pass all the data to server.

THE CPA QUALIFICATION METHOD BASED ON THE GAUSSIAN CURVE FITTING

M.T. Adithia — Mon, 01 Feb 2016 00:00:00 +0000

The Correlation Power Analysis (CPA) attack is an attack on cryptographic devices, especially smart cards. The results of the attack are correlation traces. Based on the correlation traces, an evaluation is done to observe whether significant peaks appear in the traces or not. The evaluation is done manually, by experts. If significant peaks appear then the smart card is not considered secure since it is assumed that the secret key is revealed. We develop a method that objectively detects peaks and decides which peak is significant. We conclude that using the Gaussian curve fitting method, the subjective qualification of the peak significance can be objectified. Thus, better decisions can be taken by security experts. We also conclude that the Gaussian curve fitting method is able to show the influence of peak sizes, especially the width and height, to a significance of a particular peak.

Kurniawan Kurniawan, Indah Agustien Siradjuddin, Arif Muntasa — Mon, 01 Feb 2016 00:00:00 +0000

Image security is a process to save digital. One method of securing image digital is watermarking using Least Significant Bit algorithm. Main concept of image security using LSB algorithm is to replace bit value of image at specific location so that created pattern. The pattern result of replacing the bit value of image is called by watermark. Giving watermark at image digital using LSB algorithm has simple concept so that the information which is embedded will lost easily when attacked such as noise attack or compression. So need modification like development of LSB algorithm. This is done to decrease distortion of watermark information against those attacks. In this research is divided by 6 process which are color extraction of cover image, busy area search, watermark embed, count the accuracy of watermark embed, watermark extraction, and count the accuracy of watermark extraction. Color extraction of cover image is process to get blue color component from cover image. Watermark information will embed at busy area by search the area which has the greatest number of unsure from cover image. Then watermark image is embedded into cover image so that produce watermarked image using some development of LSB algorithm and search the accuracy by count the Peak Signal to Noise Ratio value. Before the watermarked image is extracted, need to test by giving noise and doing compression into jpg format. The accuracy of extraction result is searched by count the Bit Error Rate value.

Nowadays, many schools are teaching the Chinese Language as curriculum, including elementary school. While the major problems in Chinese language learning is a form of pronunciation or intonation that much different from the Indonesia language who does not pay attention to the tone. In the Chinese language curriculum students are expected to be able to listen, to pronounce, to read and to write. Furthermore, learning arithmetic subject in Chinese language is quite difficult, because besides being able to pronounce the numbers correctly, the student should be able to count it. Hence the limitations of print media is not able to accommodate learning in listening, especially pronunciation or intonation correctly and also the writing. This led to the emergence of the spatian contiguity between text books with information on what is perceived by the learner. This study attempts to bridge these limitations by accommodating a media in web-based learning that also train the ability to listen and write, so that the spatial distance between the information in the book with a learner can be reduced . The results of this study are expected to provide a new alternative as a model for Chinese language learning, especially in Indonesia.

The World Health Organization (WHO) reported that deaths caused by cancer in the world these last four years has increased significantly. The data also reflected in the increase in breast cancer cases. In Indonesia, two cases also the highest cases of adult female deaths. Based on Hospital Information System, the number of breast cancer patients either inpatient or outpatient care amounted to 28.7%. This fact revealed more than 40% of all cancers can be prevented with early detection cancer. Role of Information Technology can implemented by data mining techniques to shorten the diagnosing time, accuracy and selection of factors early detection of breast cancer. Stepwise binary logistic regression method has the advantage to add and subtract the independent variables in accordance with level of significance of the model. Based on the analysis of weighting method, the highest four variables that should be more aware is the area of cancer (area), fineness (smoothness), the number of dots (concave points) or the nucleus of cancer and grayish level of cancer (texture). So the accuracy and processing speed of diagnosis of the severity of breast cancer can be improved through this method.

SKIN SEGMENTATION AND SKULL SEGMENTATION FOR MEDICAL IMAGING

Eric Yogi Tjandra, , Liliana, Leow Wee Kheng — Thu, 01 Jan 2015 00:00:00 +0000

In this paper aims we present tools for medical imaging applications to do skin and skull segmentation in a short time. The desired output for skin segmentation is a 3D visualization of the facial skin without any cavities or holes inside the head, while skull segmentation aims to create a 3D visualization of the skull bones. The algorithm used for skin segmentation is thresholding the image, extracting the largest connected component, and holefilling to fill the unnecessary holes. As for the skull segmentation, the process is done by removing the spines which is connected to the skull, and then extracting the largest connected component. Afterwards, mesh generation is done to produce the 3D objects from the processed images. This mesh generation process is done using the marching cubes algorithm. The testing results show that the skin and skull segmentation process will work well when there are no other objects that are connected to the skin or the skull. Skin segmentation process takes a significant amount of time, primarily caused by the holefilling process.

PT. XYZ is a company that prioritizes loyal customers. However, in its operation, PT. XYZ still has no marketing management that can support the customer loyalty, especially the electronic system ones. It can be seen when this company makes an event. The selection of the customers who can participate is done manually. In addition, there is still no system that handles the complaints from customers. Moreover, the product offering for loyal customer still has no clear system, only based on the knowledge and experience coming from sales force. On the other hand, the technology nowadays is already very developed, making it possible to make it systematic and result in high customer loyalty. The analysis results are CRM strategies, especially electronic-based (e-CRM) strategies to keep the customers loyalty and to attract new customers.

Internet facilities is one important part of the infrastructure of the campus at this time. Internet facility is a part of teaching and learning activities. Important part of the internet facility is the internet bandwidth, which is often deemed less bandwidth for certain majors at certain hours of lecture hours especially active. To overcome this there needs to be an analysis and clustering of the internet traffic at each point where the distribution of bandwidth is done so that in the end can provide information that can support decision granting bandwidth at each point there. One algorithm for clustering algorithms used are Fuzzy C-Mean, in which the clustering process before the beginning of the internet bandwidth usage data that exists in one period will be collected to be input to the Fuzzy C-Mean algorithm for the distribution of clusters on the use of existing bandwidth based applications that use the internet and network users. But the initial dataset that of the Fuzzy C Mean is not optimal, so we need some optimization dataset using feature extraction data so that the resulting clusters by Fuzzy C Mean algorithm has the accurate output. Results to be obtained from this study is the extraction of feature data that is most appropriate to perform clustering and analysis of Internet traffic based on user applications and the amount of capacity used by the user, which information the clustering results can be used to optimize internet bandwidth

PEMANFAATAN KURVA B-SPLINES UNTUK MEMPERHALUS VISUALISASI OBYEK MESH

Liliana Liliana, Gregorius Satia Budhi, Erick Leonardo, Evans Sanjaya — Thu, 01 May 2014 00:00:00 +0000

Ray tracing is one of the photorealistic rendering method. Ray tracing process takes a long time because of the calculation of lighting effects and optical effects caused by the material of the object. The length of rendering time increases with the increasing complexity of the shape of the object, such as a mesh object. To minimize processing time, generally done by reducing the complexity of the mesh, which reduces the number of face that forms a mesh object. How to reduce the number of face is to combine adjacent face to face. The downside of this method is that the object surface resulting display will look grainy/triangular - facet (checkered). The proposed method in this study aims to refine the visualization of objects that complexity is not high. Triangular surface mesh - terms appear due to the calculation of the same color for each face that form a mesh. If the face has a color gradation, the mesh will look smooth surface. To produce a color gradation on a broad face, normal calculation was used, ie in proportion adopting b - splines curve calculations. Testing is done by comparing the results of the use of normal B - splines to the simple method of subdivision (a method of face vast divide into several smaller face , so that the finer the mesh surface) with ray tracing rendering method. From the experimental results, it can be concluded that the results of ray tracing using b - splines normal when compared with the subdivision, the results are not too different. From the aspect of long rendering process, the more the number of face of a mesh, it also increase the effectiveness of rendering time process. However, the increase is not proportional to the increase in the number of mesh

PENGUKURAN KINERJA BEBERAPA SISTEM BASIS DATA RELASIONAL DENGAN KEMAMPUAN MENYIMPAN DATA BERFORMAT GML (GEOGRAPHY MARKUP LANGUAGE) YANG DAPAT DIGUNAKAN UNTUK MENDASARI APLIKASI-APLIKASI SISTEM INFORMASI GEOGRAFIS

Adi Nugroho, Sri Hartati — Sat, 01 Oct 2011 10:04:08 +0000

If we want to represent spatial data to user using GIS (Geographical Information System) applications, we have 2 choices about the underlying database, that is general RDBMS (Relational Database Management System) for saving general spatial data (number, char, varchar, etc.), or saving spatial data in GML (Geography Markup Language) format. (GML is an another XMLâ€™s special vocabulary for spatial data.) If we choose GML for saving spatial data, we also have 2 choices, that is saving spatial data in XML Enabled Database (relational databases that can be use for saving XML data) or we can use Native XML Database (NXD), that is special databases that can be use for saving XML data. In this paper, we try to make performance comparison for several XML Enabled Database when we do GMLâ€™s CRUD (Create-Read-Update-Delete) operations to these databases. On the other side, we also want to see flexibility of XML Enabled Database from programmers view.

Ibnu Gunawan — Sat, 01 Oct 2011 10:03:28 +0000

Based on data from the Internet survey from independent institutions in the United States named pewinternet as on 6 August 2008 by Deborah Fallow stating that using search engine is the second largest activity of the Internet user after e-mail, so it can not be denied that the main key to the success of a website is how the website domain listed first on the search results of a search engine. One way to ensure this is to have a high SEO score. This makes the writer is interested to conduct experiments on the relationship SEO score and ranking of a domain in search engines. Experiments carried out in an e-business lecture class, where there are 5 groups with their own domain and then we optimized their SEO. The results obtained were surprising, it turns out that high SEO score does not guarantee a high ranking and the top of the list of a search engine. This journal will explain in detail how it is done.

Andreas Handojo, Robby Adrian Joesoef, Yulia . — Sat, 01 Oct 2011 10:03:08 +0000

Nowadays, PT. Balatif has the calculation system for production cost that can only include the calculation of cost of materials based on standard Bill of Material (BOM), while record of factory overhead cost, direct labor cost and report that relating to the calculation of Cost of Goods Manufactured of product still cannot be handled by the system. So that the current costs that really occurred in the production process will be difficult to trace and the production cost not based on reality process. Based on that problem, this research design a system to calculate production cost that can handle that problem. This application used Microsoft Visual Studio .Net 2005 as the programming tool and Oracle 10g as the database. Results that obtained from the application that have been made are raw material usage can be saved based on BOM or additional, machine usage, operator usage, and so on associated with the production process. In addition, the application that has been made can be used to allocate the costs that occur during the production process and to generate reports related to the calculation of Cost of Goods Manufactured of a product automatically.

KEYWORD AND IMAGE CONTENT FEATURES FOR IMAGE INDEXING AND RETRIEVAL WITHIN COMPRESSED DOMAIN

Irianto ., Y. Suhendro — Sat, 01 Oct 2011 10:01:02 +0000

The central problem of most Content Based Image Retrieval approaches is poor quality in terms of sensitivity (recall) and specificity (precision). To overcome this problem, the semantic gap between high-level concepts and low-level features has been acknowledged. In this paper we introduce an approach to reduce the impact of the semantic gap by integrating high-level (semantic) and low-level features to improve the quality of Image Retrieval queries. Our experiments have been carried out by applying two hierarchical procedures. The first approach is called keyword-content, and the second content-keyword. Our proposed approaches show better results compared to a single method (keyword or content based) in term of recall and precision. The average precision has increased by up to 50%.

ACHIEVING VALUE FROM ICT IN SMES: KEY MANAGEMENT STRATEGIES

K. Johnston, S. Parker, K.D. Tu, F. Mosoval — Thu, 02 Dec 2010 14:13:51 +0000

ICT covers a broad range of fields in business and therefore makes ICT value difficult to simply define. The main factors that influence the use of ICT are therefore important to look at, as they give a good understanding of the how much influence the organisation has, on achieving value in its given context. The transformational model of ICT use was analysed to establish how SMEs in South Africa achieve business value from ICT and what management practices are most effective. Implications of the research are that management practices are an important factor that influences the value from ICT, and that the more management practices organisations implement, the greater the business value from ICT. Further findings of this study deduced that organisations that are more ICT aware, gain greater business value from ICT, with value achievement from ICT largely within the organisationâ€™s control. This paper concludes with recommendations for future research.

PEMBUATAN RENCANA KEAMANAN INFORMASI BERDASARKAN ANALISIS DAN MITIGASI RISIKO TEKNOLOGI INFORMASI

Aan AlBone — Thu, 02 Dec 2010 14:12:55 +0000

An information security plan consists of strategies and shared responsibility, the main aim is to reduce the risk of a potential threat to the company's operations. If the security plan is not based on the results of risk analysis, can cause weakness in the strategy to anticipate the threat of disruption and attacks on corporate assets. Weak strategy, caused by the process of identifying weaknesses and vulnerabilities of information technology is not done properly. Instead of the security plan should be based on the results of analysis and information technology risk mitigation, so that the security of the proposed strategy can effectively reduce the risks identified through risk analysis and mitigation. The process of risk analysis in addition to producing the identification of risk, also providing recommendations appropriate security controls with the risk would be reduced. The recommended security controls on risk analysis, will then be evaluated from the aspects of effectiveness and efficiency in reducing any risk, the risk mitigation process, so that this process will provide a strong foundation in information security plan to determine an overall, effective and efficient, since it is based with the impelementasinya priority. Sebuah rencana keamanan informasi terdiri atas strategi dan pembagian tanggungjawab, yang bertujuan utama untuk menurunkan risiko yang berpotensi menjadi ancaman terhadap operasional perusahaan. Jika penyusunan rencana keamanan tidak berdasarkan hasil analisis risiko, akan dapat menyebabkan lemahnya strategi dalam mengantisipasi ancaman gangguan dan serangan terhadap aset perusahaan. Lemahnya strategi tersebut, disebabkan oleh proses identifikasi kelemahan dan kerawanan teknologi informasi yang tidak dilakukan dengan baik. Sebaliknya dalam penyusunan rencana keamanan seharusnya didasari oleh hasil analisis dan mitigasi risiko teknologi informasi, agar strategi keamanan yang diusulkan dapat secara efektif menurunkan risiko yang telah diidentifikasi melalui analisis dan mitigasi risiko. Proses analisis risiko selain menghasilkan identifikasi risiko, juga memberikan rekomendasi kontrol keamanan yang sesuai dengan risiko yang akan diturunkan. Kontrol keamanan yang direkomendasikan pada analisis risiko, selanjutnya akan dinilai kembali dari aspek efektivitas dan efisiensi dalam menurunkan setiap risiko, pada proses mitigasi risiko, sehingga proses ini akan memberikan dasar yang kuat dalam menentukan rencana keamanan informasi yang menyeluruh, efektif dan efisien, karena didasarkan dengan prioritas implementasinya.
