Abstract

ABSTRACT---Tuberculosis (TB) is an infectious disease caused by the bacteria mycobacterium tuberculosis. TB is the number one killer among infectious diseases, and even Indonesia occupies the fifth largest country in the world in this disease problem. Detection of TB disease through clinical symptoms, laboratory tests and thoracic imaging (lung) with x-ray. The research was conducted to determine the histogram and the average value of gray scale image of the thoracic patients suffering from TB and who is not. By knowing the value of the histogram and the mean gray scale this can later be used as additional instructions for medical personnel to diagnose, i.e. to determine whether the patient has TB or not. In this research, the exposure factors was carried out with a tube voltage of 55 kV, tube current 200 mA and time 0.08 s, using of the Computed Radiography (CR). Histogram analysis performed on the Region Of Interest (ROI) that is at the apex of the lung and superior lung lobes contained patches of gloom on the image of the thorax. It was obtained that the image histogram from TB patients shifted to the right or the gray scale pixel values have a higher (brighter). The average value of pixel gray scale image of the patient suffering from tuberculosis at 13,3 and for patients who are suffering from TB at 61,6.Key words: thoracic imaging, Tuberculosis, histogram ABSTRAK---Penyakit Tuberculosis (TB) merupakan suatu penyakit menular yang disebabkan oleh bakteri mycobacterium tuberculosis. TB merupakan pembunuh nomor satu diantara penyakit menular, bahkan Indonesia menduduki negara terbesar kelima di dunia dalam masalah ini. Deteksi penyakit TB dilakukan melalui gejala klinis, uji laboratorium dan foto thoraks (paru-paru) dengan sinar-x. Penelitian inidilakukan untuk mengetahui histogram dan nilai rerata sekala keabuan citra thoraks pasien yang menderitaTB dan yang bukan. Dengan mengetahui nilai histogram dan nilai rerata sekala keabuan ini nantinya dapat dijadikan petunjuk tambahan bagi tenaga medis untuk menegakkan diagnosa, yaitu untuk menentukan apakah pasien menderita TB atau tidak. Dalam riset ini, eksposi dilakukan pada tegangan tabung 55 kV, arus tabung 200 mA dan waktu 0,08 S, serta menggunakan Computed Radiography (CR). Analisis histogram dilakukan pada Region Of Interest (ROI) yaitu pada daerah apeks paru dan lobus superior paru yang terdapat bercak-bercak kesuraman pada citra thoraks. Dari penelitian diperoleh bahwa histogram citra pasien penderita TB bergeser ke sebelah kanan atau mempunyai nilai skala keabuan piksel yang lebih tinggi (lebih cerah). Nilai rata-rata skala keabuan piksel citra pasien yang menderita TB sebesar 136,3 dan tidak menderita TB sebesar 61,6.Kata kunci: pencitraan thoraks, Tuberculosis, histogram

Abstract

The curve of 2D isodose is used to determine the dose distribution in patient treated by radiotherapy. Therefore, isodose curve is very useful for planning and evaluating of the dose received by the patient. Correction of 2D isodose curve for sloping surface is very important due to the skin of patient is not flat. In this study, the correction of isodose curve was calculated using tissue air ratio (TAR) method for radiation field size of 10x10 cm2. The correction factor was obtained by comparison of TAR value for effective depth and TAR value for total depth. The correction factor then was multiplied to isodose curve for flat surface. In this study, the software for calculating the automated correction factor due to sloping of patient surface has been successfully developed. It was found that if the sloping of patient surface increases then the corrected isodose curve increases. Key wods: 2D isodose curve, tissue air ratio (TAR), correction factor, sloping patient surface.

Abstract

Diabetic Retinopathy is a complication of Diabetes Melitus. It can be a blindness if untreated settled as early as possible. System created in this thesis is the detection of diabetic retinopathy level of the image obtained from fundus photographs. There are three main steps to resolve the problems, preprocessing, feature extraction and classification. Preprocessing methods that used in this system are Grayscale Green Channel, Gaussian Filter, Contrast Limited Adaptive Histogram Equalization and Masking. Two Dimensional Linear Discriminant Analysis (2DLDA) is used for feature extraction. Support Vector Machine (SVM) is used for classification. The test result performed by taking a dataset of MESSIDOR with number of images that vary for the training phase, otherwise is used for the testing phase. Test result show the optimal accuracy are 84% .   Keywords : Diabetic Retinopathy, Support Vector Machine, Two Dimensional Linear Discriminant Analysis, MESSIDOR

Abstract

Prediksi harga saham berguna bagi investor untuk memahami bagaimana investasi masuk dalam suatu organisasi di masa depan. Prediksi dapat mengantisipasi fluktuasi harga saham dan juga dapat membantu investor untuk membuat keputusan. Jaringan Syaraf Tiruan (JST) menyediakan cara yang cepat dan fleksibel untuk memprediksi harga saham, dan menunjukkan hasil yang baik dibandingkan dengan metode konvensional. Algoritma yang digunakan untuk prediksi saham adalah backpropagation dengan model data time series. Algoritma ini merupakan metode pelatihan terawasi yang berfungsi untuk meminimalkan error pada output yang dihasilkan oleh jaringan. Hasil penelitian ini menunjukkan bahwa hasil optimal yang diperoleh dari Jaringan Syaraf Tiruan adalah menggunakan kombinasi fungsi aktivasi Logsig-Purelin, dengan tingkat nilai Mean Absolute Percentage Error (MAPE) adalah 2.43% dan nilai koefesien korelasinya adalah  94.08%, sehingga algoritma ini layak dan efektif untuk prediksi harga saham.   Kata kunci : Jaringan Syaraf Tiruan, Backpropagation, Peramalan, Harga Saham, Time Series

Abstract

Texture is one of the most important features for image analysis, which provides informations such as the composition of texture on the surface structure, changes of the intensity, or brightness. Gray level co-occurence matrix (GLCM) is a method that can be used for statistical texture analysis. GLCM has proven to be the most powerful texture descriptors used in image analysis. This study uses the four-way GLCM 0o, 45o, 90o, and 135o. Support vector machine (SVM) is a machine learning that can be used for image classification. SVM has a high generalization capability without any requirement of additional knowledge, even with the high dimension of the input space. The data used in this study are the image of goat meat, buffalo meat, horse meat, and beef with shooting distance 20 cm, 30 cm and 40 cm. The result of this study shows that the best recognition rate of 87.5% was taken at a distance of 20 cm with neighboring pixels distance d = 2 in the direction GLCM 135o.

Abstract

The application of current technology such as the Radiology Information System Picture Archiving and Communication System (RISPACS) in radiology that doesn’t meet the user’s expectation can raise the inconvenience and affect their productivity. To anticipate this, it is important to understand the basic factors that contribute to the reception and successfulness of applicating RISPACS. This study aims to describe the evaluation of the successful implementation of RISPACS using the Human Organization Technology (HOT FIT) model approach in Radiology Installation at Sanglah Hospital Denpasar. The data in this research were analyzed by Partial Least Square (PLS) test and measuring 71 radiologists as respondents who use RISPACS. The evaluation results of the Human Organization Technology (HOT FIT) model show that the successful implementation of RISPACS technology has a positive assessment that is seen from the user's attitude in responding to a RISPACS technology that is felt to be in accordance with the expectations and operational needs of the user. Variable of system quality, information quality, service quality have a positive influence on system user variable and user satisfaction. While the variable of system users, user satisfaction, organizational structure, and organizational environment had a positive and significant effect by the t-statistic value of >1,96.
