Abstract

Pornographic image recognition is a matching process between an image signature of pornographic training image and an image signature of query image. The aims of this research were to build pornographic image recognition system based on image content that can classify an image that is porno or not and to know how the performance of this method is. Image content that was used in this research was color content and image signature. The image content was taken by color histogram and by extracting an image using wavelet transform, next choosing a little wavelet transforms coefficients that have the biggest magnitude value and moment was used to sharpness the image information content. The tests were carried out in Daubechies 8 wavelets type, 25 heterogeneous pornographic images for training and 500 query images that consist 125 heterogeneous pornographic images and 375 non-pornographic images. Screening success rates were determined by using number images that can be screening per number images on database in percentage, and screening time was determined by the time that needed for an image to classify as pornographic image. The results show that this method give average of screening success rate about 67.02% (it means can classify 84 images as pornographic from 125 pornographic images in database) and can classify about 36 images as pornographic from 375 non-pornographic images in database. This system also needs a little time for screening process that is about 0.29 second every image and screening time is linear to size of database. This method is good enough as pornographic image screening but need some improvement for increasing the performance. Abstract in Bahasa Indonesia : Pengenalan citra merupakan proses pencocokan antara ciri-ciri citra citra query dengan ciri-ciri citra pelatihan yang tersimpan dalam basis data (citra pustaka). Penelitian ini merupakan pengenalan citra porno berbasis kandungan informasi (image content) citra yang bertujuan untuk membangun sistem yang dapat melakukan pengenalan apakah suatu citra berkategori porno atau bukan dan untuk mengetahui keefektifan teknik ini. Kandungan informasi yang dimaksud adalah informasi warna dan ciri-ciri citra (image signature) yang di peroleh dengan cara teknik histogram warna dan mentransformasi-wavelet-kan citra dan memilih sebagian kecil (m) koefisien hasil transformasi yang memiliki nilai magnitude terbesar yang selanjutnya ciri-ciri citra dikenakan proses penghitungan momen untuk penajaman informasi citra. Informasi ini yang digunakan sebagai basis pengenalan. Pengenalan citra porno menjadi sulit karena citra porno memiliki tingkat heterogen yang tinggi seperti memiliki pose, warna latar belakang, diambil dari sudut kamera, warna kulit, dan etnis yang berbeda. Sistem ini diujikan pada wavelet jenis Daubechies 8, 25 citra porno heterogen untuk pelatihan, dan 500 sample citra query yang terdiri dari 125 citra porno heterogen dan 375 citra non-porno. Tingkat kesuksesan pengenalan dihitung dengan menggunakan nilai persentase dari jumlah citra porno yang dikenali terhadap jumlah total citra porno yang terdapat dalam basis data dan waktu pengenalan merupakan waktu yang diperlukan oleh sistem untuk mengklasifikasikan sebuah citra sebagai citra porno atau bukan. Hasil pengujian menunjukkan bahwa tingkat kesuksesan pengenalan citra porno menggunakan metode ini sebesar 67.02% (dapat mengenali sebanyak 84 citra sebagai citra porno dari 125 citra porno yang diuji) dan mendeteksi citra non-porno menjadi porno sebanyak 36 citra dari 375 cita non porno (9.06 %), Waktu pengenalan bersifat linear terhadap ukuran data basis data dan waktu pengenalan relatif pendek yaitu rata-rata untuk setiap citra sebesar 0.29 detik. Hasil ini menunjukkan transformasi wavelet cukup baik digunakan sebagai pemroses-awal (pre-processing) citra dan moment sebagai penajam informasi untuk pengenalan citra porno atas kandungan informasi (image content) dari citra, namun perlu diteliti lebih lanjut sehingga tingkat kesuksesan lebih baik. Katakunci: sistem pengenalan, citra porno, transformasi wavelet, momen, dan ciri-ciri citra.

Abstract

Image retrieval was a matching process between feature of query image and feature of target image. Image retrieval was a very interesting project because many institutions such as artistic gallery and police used it. This paper explained about image retrieval method that was used to retrieve image from a collection of images. The method was sorted wavelet histogram. The method was a result of development of previous image retrieval which implements histogram to wavelet transforms coefficients for feature extraction. The retrieval application just runs in the computer when the test was carried out. The result showed that this method gave good performance which the average of succeed rate was 100% for original image, 99,83% for the image of Blur, 90,25% for edge image and 73,57% for the 50% salt & paper noise image and the querying time is about 0.2 second.

Abstract

The paper proposed a pornographic image recognition using skin probability and principle component analysis (PCA) on YCbCr color space. The pornographic image recognition is defined as a process to classify the image containing and showing genital elements of human body from any kinds of images. This process is hard to be performed because the images have large variability due to poses, lighting, and background variations. The skin probability and holistic feature, which is extracted by YCbCr skin segmentation and PCA, is employed to handle those variability problems. The function of skin segmentation is to determine skin ROI image and skin probability. While the function of PCA is to extract eigenporn of the skin ROIs images and by using the eigenporns the holistic features are determined. The main aim of this research is to optimize the accuracy and false rejection rate of the skin probability and fusion descriptor based recognition system. The experimental result shows that the proposed method can increase the accuracy by about 12% and decrease the FPR and FNR by about 16%, respectively. The proposed method also works fast for recognition, which requires 1.3.second per image.

Abstract

One of the tasks of a university is teaching. To keep the quality by improving the teaching qualifications, materials, teaching facilities, and infrastructure. but, one of the important things is to keep the quality of teaching. The quality of teaching can be measured from the feedback of the students. Informatics Department of Mataram University has a system to get feedback from its students called SIKBM (a questioner system for teaching). Unfortunately, not of all the students will fill this questioner because there is no interest for the students. So, we apply a web service system that connects SIKBM and SIA (academic information system). It will force the students to access SIKBM as a requirement to fill KRS (Course selection sheet) on SIA. The result shows that on even semester of 2017, we gain feedback for all of the courses we did not get in the previous years.

Abstract

School accreditation is public accountability carried out objectively, fairly, transparently and comprehensively. The instruments used in the school accreditation assessment process refer to the National Education Standards which have eight Standard Points. Since there are many standards and criteria that must be met, the school will difficult to fulfill and measure its performance. This study aims to assist schools in carrying out the performance evaluation process, to meet the standards and criteria that refer to the National Education Standards. In this study a system was developed that can help prepare school accreditation, by providing forms that must be filled in by the school and the system will automatically measure school performance, so that the school can find out its weaknesses to be improved immediately. In its development, the Laravel framework was used with PHP, HTML, and JavaScript as a programming language. The development method used was the waterfall method. System testing in this study uses three testing methods, namely unit testing, black box and MOS (Mean Opinion Score).

Abstract

This study discusses the design of information technology enterprise architecture in the cooperation of Budi Karya. The main problem encountered is that the management still uses a bookkeeping system. The information obtained in each section has not been integrated with other, the IT management organization structure is not sufficient because there is no staff who have specialized IT experts, and require development in information technology. This was stated in one of the Budi Karya cooperation missions which read "Adopting the development of information technology and modern management systems". This study aims to produce process architecture, data, applications and technology that can be a reference for implementing all activities in cooperation of Budi Karya. This research uses the TOGAF (the Open Group Architecture Framework) which is a framework that has detailed methods and tools for developing and implementing enterprise architecture, with 8 architectural phases of vision, business architecture, information system architecture, technology architecture, opportunities and solutions, migration plan, implementation Governance, and architecture change management. Data collection is done by direct observation interviews and literature studies. The results of all these phases will produce a detailed framework of process architecture, data architecture, application architecture, and architecture in cooperation of Budi Karya Keywords: Enterprise, Architecture, Cooperation, framework, TOGAF

Abstract

Small and Medium Industries (SMIs) have a very important role as a driver of the economy in Indonesia because SMIs can function as a provider of employment for a number of people who are not accommodated in the formal sector. SMIs also contributes to the formation of Gross Domestic Product (GDP) and as a source of foreign exchange. However, SMIs experienced obstacles in the fields of marketing, business networks, and information technology. In realizing an independent and developing SMIs, a supporting media is needed which can later be useful as a tool to introduce SMIs to the wider community and align it with other business actors. In addition, the government also needs a media that can be used for licensing data collection, taxes, and as a tool to monitor the development of SMIs. In this case a geographic and web-based geographic information system has been built to meet the need for information on SMIs in the city of Mataram. It is hoped that this system can help the community and the government to find out the information needed easily, quickly, and accurately. Based on the results of the Mean Opinion Score, it shows that the average rating of respondents of website users on the system agrees and strongly agrees to agree worth 67.50%. While the average rating of respondents of mobile users to the system agree and strongly agree is worth 78.33%.

Abstract

The thesis is one of the graduation requirements that students must take to obtain a bachelor's degree. Each student informatics study program who will carry out the Thesis will do several processes, including the process of registration of titles, guidance, registration of Thesis seminars, Examination and judiciary sessions. The thesis administration process is still running manually, where at the time of title registration, students must fill in the form of thesis title. After that, students will wait for the announcement to find out their supervisor as well as the registration of the Thesis Seminar, the examination, and the Judiciary sessions. Students must come directly to the office with the registration requirements. The process requires a long time so that thesis administration services become less effective. Therefore a website-based Thesis Information System was built which aims to facilitate the thesis administration process of Informatics study programs. Based on black box testing, this system was declared to have run well while testing using the MOS method showed that 95.34% of informatics student respondents, 99.33% of non-informatics student respondents, and 100% of lecturers and admin respondents agreed. Therefore this system is suitable for use. Keywords: Thesis, website-based, black box, MOS.
