In this day and age many people use the internet with wifi media because its use is easy and efficient, in contrast to the use of network cables because of its inefficient use and consuming a lot of space. But now the use of wifi is widely accessed by unauthorized people to access it and insecure login verification process and the amount of access that uses wifi on one SSID will result in a decrease in internet speed on wifi, to enter and verify it into a wifi network. text and numbers or security using the QR Code. Using a QR Code or an ordinary password will not be able to deal with people who are not entitled to such access, so it needs layered security to secure and verify wifi logins from people who are not entitled to access them. Base64 algorithm is one of the algorithms for encoding and decoding a data into an ASCII format, which is based on basic numbers 64 or can be referred to as one method used to encode binary data. In securing wifi by verifying the QR Code login wifi network using the base64 algorithm makes using wifi can be overcome and handled so that no one breaks into the wifi network because it can harm the users or owners of the wifi network

Of the various functions that exist in a company engaged in the business world, the function of marketing or marketing functions is a very vital and strategic function for the company concerned. The rapid development of the business world, accompanied by increasingly intense business competition, has actually strengthened the position of the marketing aspect of this vital and strategic position, Sales are the jobs most needed by the company, these 10 specialties, total vacancies for sales are 19%, followed by financial default by 18%, while IT / communication amounts to 13%. Job vacancies as sales are widely available, but lack of interest, therefore companies find it difficult to find employees in the sales department The COPRAS method assumes a direct and proportional dependence on the level of significance and utility of the alternatives in the presence of conflicting criteria. This takes into account the performance of alternatives with respect to different criteria and also the weight of the appropriate criteria. This method chooses the best decision considering the ideal and ideal solution - worst. The COPRAS method used here for decision making in the manufacturing environment adopts a six-stage procedure ranking and evaluates alternatives in terms of their level of importance and usefulness. The COPRAS method has the ability to take into account positive (favorable) and negative (unfavorable) criteria, which can be assessed separately in the evaluation process. The most important feature that makes the COPRAS method superior to other methods is that it can be used to calculate the level of alternative utility that shows the extent to which alternatives are taken for comparison

Comic is a work of art that is designed using a collection of still images and is complemented by a text or story. Comics are a reading book needed by children and teenagers alike. In comics, apart from the interesting content of the stories, there are also moral messages embedded in each story. However, with the development of technology, there are many comics whose stories do not educate teenagers' characters, starting from pictures and no more educational moral messages embedded in the stories. The solution drawn from this problem is by designing an Android-based comic application that can be easily accessed and understood by the public, especially teenagers. However, due to the limitations of smartphone applications to present comic episodes, string matching is needed to search for comic titles. The string matching algorithm is a string matching algorithm that looks for a string consisting of several patterns (characters) in a large amount of text. For android-based comic applications, it is designed using the Crochemore-perrin algorithm

Derivative filtering algorithm is the formulation of mathematical derivative concepts beginning with understanding the concepts of calculus applications, especially differential theory (derivatives) in digital formulations. The method used in the formulation of this theory is to seek, collect and study several theories related to differences and their applications. The derivation technique can be described as calculating the rate of brightness values in a discrete digital image, also known as an image derivation technique. Sharpening will be obtained by calculating the difference in brightness values between adjacent brightness values in the same column and row. Image is the overall result of a data recording system. Theoretically, images can be grouped into 2 (two) types, namely continuous images and discrete images (digital images). A continuous image is generated from an optical system that receives an analog signal. Example: human eye, analog camera. Meanwhile, digital images are generated through the process of digitizing continuous images. Example: digital camera.

Detection of similarity in text documents is needed to avoid the accumulation of information in a database or file system, one way to find out plagiarism between two documents by detecting the similarity of two documents to be compared to detect plagiarism, the Shingling Algorithm is an algorithm used for near-duplicate document search processes. Shingling's algorithm is implemented to detect similarities in text documents. The ease of copying information from one document to another is one of the effects of advances in information technology. And this leads to unwanted plagiarism, so that the document detection process can be minimized properly. In this study, the test results show that the application created can detect the similarity of text documents that have gone through various manipulations, namely scaling (enlarge / reduce), rotation, cropping (partially cut), and manipulating documents.

Digital image management generally refers to processing two-dimensional images using a computer in a broader context. Image restoration is image pemamangan by eliminating or reducing degradation of the image that occurs due to the process of image acquisition. The scanned image is the process of moving images (images) using a scanner which often experiences a decrease in image quality (degraded). This results in inaccurate results in digital image processing such as blur / blur, spots, dual images, over saturated colors, and pixel errors. Caused by external factors (noise). Iterative lanczos-Hybrid Reqularization method is one of the choices of effective methods in solving the blur or noise problem that causes the image quality to decrease or not match the original image. In the process of digital image restoration scan results that have degraded can be maximized well from the original image, in this study the Iterative lanczos-Hybrid Reqularization method of image restoration used can provide more optimal results with more effective and efficient time.

The economy that is happening in Indonesia is not balanced because of the large economic disparity between one region and another, this can be seen clearly from the uneven income of the people and the poverty problems that occur in terms of clothing, food and shelter. The community has the right to get proper clothing, food and shelter for the sake of creating a prosperous society. If one of them is still not fulfilled, then prosperity will not be achieved. To realize this, the government has held various poverty reduction programs, one of which is in the form of social funds provided to the poor. Problems that often occur in determining the eligibility of receiving assistance. The assessment process of the beneficiary community in Tuhtuhan Village is not yet perfect, only covering the type of work, total income, number of dependents and age. This method of assessment is subjective, which can lead to social jealousy for those who do not accept it. From the above problems, it can be solved by utilizing computer technology to create a Decision Support System (DSS). One of them is by using the Moora method. The MOORA (Multi Objective Optimization on the Basis of Ratio Analysis) method is applied to solve many economic, managerial and construction problems. math formula calculations with exact results

White blood cells are cells that form components in the blood. White blood cells have a life span of between six to eight days. Analyzing white blood cells is still carried out through a series of laboratory tests which can take a while. This test covers the shape of the morphology of blood cells, which until now is generally still done manually. This manual inspection certainly has a low level of accuracy and accuracy because it is carried out humanely and has a possible degree of difference in analysis. This causes a lack of accuracy and accuracy performed by doctors and health laboratory personnel because the physical condition, knowledge, accuracy and concentration of doctors and health laboratory personnel can influence the identification of diseases so that there may be differences in analysis between one doctor and another. On hematology examination can be overcome manually by creating an automatic system with the help of a computer. Therefore, in this study the author tries to provide alternative solutions to the problem with the Radial Basis Function learning method, which according to his theory will produce higher accuracy values and faster iteration times
