<![CDATA[Anemia is a condition in which the level of hemoglobin in a person's blood is below normal. Hemoglobin concentration is one of the parameters commonly used to determine a person's physical condition. Anemia can attack anyone, especially pregnant women. Currently, many non-invasive anemia detection methods have been developed. One of non-invasive methods in detecting anemia can be seen through its physiological characteristics, namely palpebral conjunctiva images. In this study, conjunctival image-based anemia detection was carried out using one of the deep learning methods, namely Convolutional Neural Netwok (CNN). This CNN method is used with the aim of obtaining more specific characteristics in distinguishing normal and anemic conditions based on the image of the palpebral conjunctiva. The Convolutional Neural Network proposed model in this study consists of five hidden layers, each of which uses a filter size of 3x3, 5x5, 7x7, 9x9, and 11x11 and output channels 16, 32, 64, 128 respectively. Fully connected layer and sigmoid activation function are used to classify normal and anemic conditions. The study was conducted using 2000 images of the palpebral conjunctiva which contained anemia and normal conditions. Furthermore, the dataset is divided into 1,440 images for training, 160 images for validation and 400 images for model testing. The study obtained the best accuracy of 94%, with the average value of precision, recall and f-1 score respectively 0.935; 0.94; 0.935. The results of the study indicate that the system is able to classify normal and anemic conditions with minimal errors. Furthermore, the system that has been designed can be implemented in an Android-based application so that the detection of anemia based on this palpebral conjunctival image can be carried out in real-tim.]]>

<![CDATA[Today, the security of information and data is an important asset for everyone in protecting data. Data and information become critical when weaknesses and threats come. In this study, an estimation of the observed variables will be carried out. The application of data mining, especially with the estimation method by using linear regression techniques. The next stage is data preparation by referring to the dataset recorded in the user activity log. Data preparation takes a lot of time because you have to make sure the data fits the needs of data mining analysis. The analysis technique with linear regression involves three independent variables as Type Permissions, Type of User Account, Status, and the dependent variable, namely User Actions. The strongest effect was found in type_permissions and state when together on user_actions. The type_permissions variable keeps increasing when the state on the user is active. The status attribute also suffers from the same condition. Accrording to the results, our findings in root mean squared error is 37.614 and absolute error is 31.058, and mean absolute percentage about 23%. Furthermore, User_action as an estimated variable gives two data opportunities whether it is allowed or not. Therefore, in future research, it is necessary to map users of the database system still in the context of data mining when digging for information on excessive permissions.]]>

<![CDATA[In the 4th Industrial revolution, science and technology became increasingly advanced and more evolved. Besides that, data also became a new commodity that can be used to accomplish various things. One of the Indonesian retail companies that used data to improve the quality of the product is PT. XYZ. The oracle form is an application of form that used by PT XYZ for data collection. But the oracle form can no longer complied the company's needs, so the company needs an alternative form application that can be used to replace the oracle form. Therefore, a web-based form application was created and combined with dynamic scripting. Dynamic scripting was a proggraming technique to avoid writing the same code repeatedly. In this study, dynamic scripting's application was combined with the webix framework, resulting in a new framework that can shorten the code line and increase the time efficiency of the building of the form application.]]>

<![CDATA[UD Dunia Sakti Kisaran is a business engaged in the sale of Yamaha motorcycles. Existing activities in the company include stock purchase transactions and sales transactions. The problem that occurs in the company is that stock purchase transactions often have difficulty in determining how much stock to buy for the next period. This results in frequent shortages of stock or even a lot of stock remaining so that it cannot meet customer needs and the accumulation of goods in the warehouse for a long period of time. Sales predictions made by the company are only based on estimates, resulting in increased storage in the warehouse, and increased maintenance costs. To meet consumer needs, the company has not used a mathematical model in estimating the amount of demand for Yamaha motorcycles in the future. Problems like this make activities at UD Dunia Sakti Kisaran less effective in the process of selling and buying stock. To overcome this, a forecasting system is made using the web-based Weighted Moving Average (WMA) method using the PHP programming language and MySQL database. The forecasting system that is designed can provide convenience in forecasting sales of Yamaha motorcycles at UD Dunia Sakti Kisaran in the coming period using the Weighted Moving Average method. By using the WMA method, the average error results obtained for the types of Yamaha NMAX, VIXION, LEXI, XSR, FREEGO and GEAR motorcycles are with an error rate or MAPE value ranging from 19.22%-31.11%, meaning that the model's capability the resulting forecast is feasible/adequate.]]>

<![CDATA[The COVID-19 pandemic has forced daily face-to-face activities to be carried out online using video conferencing applications. To record participant participation in meetings using a video conference application, an online form application is used. However, participants sometimes do not see this and are often missed due to the large number of incoming chats. Therefore, the use of face detection for attendance using a combination of CNN to detect all the faces in a video conference using YOLO Face and CNN to recognize the owner of a face using Smaller VGG in a pipeline will make it easier to recognize participants who are present at the video conference. The results of the Smaller VGG training are obtained, namely the loss value of 0.059, the accuracy value is 0.995, the recall value is 0.994, the precision value is 0.996. Meanwhile, for the validation phase of the model, the loss value is 0.497, the accuracy value is 0.979, the recall value is 0.979 and the precision value is 0.981. In terms of training duration, the smaller VGG has a duration of 4 minutes and 16 seconds. The Smaller VGG model was combined with YOLO to create a CNN pipeline and was successful in recognizing the faces of video conference participants]]>
