MACS segmentation is very difficult because of the many overlapping object characteristics in the temporal bone. This study aims to accurately identify and measure MACS areas from CT-scan images of mastoiditis patients. The data tested consisted of 128 CT images from 13 different patients. Images were taken using the Siemens SOMATOM Perspective CT Scanner model 10662260 axially. The extended Adaptive Threshold (eAT) method was developed to produce optimal threshold values for each test image. Furthermore, the eAT results are used to convert the test image into a binary image and then applied to the identification and extraction model automatically for reconstruction from 2D to 3D images. Smaller MACS sizes indicate inflammation of the mastoid bone and require intensive care. Thus, this research can be used to help doctors make the right decisions in carrying out furthe...

Almost all pharmacies experience the same problem, causing many people who do not to get their drug needs during the current pandemic. To overcome this, analyzing the process of predicting drug demand in the next period is necessary. The prediction process can be used as an initial solution in solving problems to see the number of drug demand numbers that will occur. This study aims to develop a predictive analysis model for drug demand using a deep learning approach and a classification model. Deep learning is an approach that does well in the case of prediction. The classification model also includes the right concept for solving the problem. The prediction and classification analysis methods include K-Means clustering, Multiple Linear Regression (MRL), Artificial Neural Network (ANN), and Decision Tree algorithms C.45. This method can provide better performance results in the prediction process to get precise and accurate output. Prediction results obtained from the learning process provide an accuracy rate of 99.99%. The output of the classification model also provides an overview of the knowledge base in the form of a decision tree. The level of classification model testing carried out gives the accuracy of the classification pattern of 97.05% so that the analytical model developed can predict future drug demand.

The mastoid bone consists of the mastoid air cell system (MACS) which protects the ear structures and regulates air pressure in the ear and has different sizes and characteristics, making it very difficult to identify precisely. This study aims to identify and find the right MACS size by developing an automatic identification model and obtaining the optimal threshold value in the segmentation process using the extended adaptive threshold (eAT) method. The research dataset uses computed tomography (CT)-scan images of 308 slices of 12 patients indicated for mastoiditis. The results of this study provide identification that has the right MACS accuracy and size. Overall, the optimal segmentation process obtained the smallest threshold value of 57 and the largest threshold value of 63, the smallest MACS size is 4.025 cm2 and the largest is 8.816 cm2 with an accuracy rate of 93.4%. The smaller MACS s...

Visually, the information temporal CT image mastoid bone has can assist medical experts in viewing the mastoid air cell system (MACS), but the fact that medical personnel are experiencing difficulties in determining the size MACS is due to the many different characteristics and objects overlap, so that in the measurement of the area, precise and accurate results have not been obtained. This study aims to separate the object of the MACS with the development of extraction. The proposed method uses Morphology and Regionprops operations. The dataset used in the testing process is 347 of 5 patients indicated for Mastoiditis. The results obtained can calculate the area of MACS for each test image. Based on image testing, the area of the smallest MACS in this study was 0.589 cm2 and the largest was 6.183 cm2. This, the smaller the size of the MACS indicates...

This is done to find out the types of products that have high and low sales levels. This study uses the C45 Data Mining Algorithm concept that will produce a conclusion on the prediction of sales of pharmaceutical products through data processing obtained from sales transactions at pharmacies. This C45 algorithm will form a decision tree that provides users with knowledge about products that are in great demand by consumers based on sales data and predetermined variables. The final result of the C45 algorithm produces a number of rules that can identify the inheritance of a type of medicinal product. C45 algorithm is able to produce 20 types of categories that will be labeled goals based on the number of pharmaceutical products, since it can be concluded that C45 successfully defines 55% of the existing objective categories.

Covid-19 spread so fast to 196 countries, including Indonesia. The government has to study the pattern and predict its spread in order to make policies that will be implemented to tackle the spread of some of the existing data. Therefore this research was conducted as a precautionary measure against the Covid-19 pandemic by predicting the rate of spread of Covid-19. The application of the machine learning method by combining the k-means clustering algorithm in determining the cluster, k-nearest neighbor for prediction and Iterative Dichotomiser (ID3) for mapping patterns is expected to be able to predict the level of spread of Covid-19 in Indonesia with an accuracy rate of 90%.

It has generated a very significant interest in educational, industrial and business set-ups due to its many benefits. However, cloud computing is still in its early stage of development and is faced with many difficulties. Researchers have shown that security issues are the major concerns that have prevented the wide adoption of cloud computing. One of the security issues is privacy which is about securing the personal identifiable information (PII) or attributes of users on the cloud. Although researches for addressing privacy on the cloud exist (uApprove, uApprove.JP and Template Data Dissemination (TDD)), users’ PII remains susceptible as existing researches lack efficient control of user’s attribute of sensitive data on the cloud. Similarly, users are endangered to malicious service providers (SPs) that may connive to expose a user’s identity in a cloud scenario. This paper provides a mechanism to solve the malicious SP collusion problem and control the release of user’s attribute in the cloud environment. This will require the use of policies on the SPs, where SPs are only allowed to request for attributes that are needed only to process a user’s service at any point in time. This can be achieved using a combination of Kerberos ticket concept, encryption and timestamp on the attribute to be released to SPs from the identity provider (IdP), thereby helping to control attributes given to SPs for processing the release of services to users for one-time usage by the SPs and not kept for future use by them. Thus, replay attacks and blocking other SPs from accessing them are prevented. Hence, any malicious intention of assembling users’ attributes by other SPs to harm them is defeated.

On the previous website the security used was not optimal in securing the website so we needed a reliable website security. XML (eXtensible Markup Language) is a markup language that is designed to store and deliver data by forming its own tags as needed. Codeigniter Framework is a php framework that is open source and uses the MVC method (Model, View, Controller). codeigniter is free or not paid if you use it. Codeigniter framework is made with the same purpose as other frameworks, namely to facilitate developers or programmers in building a web-based application without having to create it from scratch. The results of testing of this method are able to help and minimize the entry of hackers and secure data that will later become information.
