Abstract

A credit card application is a financial facility that allows a person or business entity to borrow money to buy a product and pay it back within a specified time. Credit card manufacture often experiences risk in providing credit, both moderate, good and very good risk, due to lack of data analysis and lack of attention. So the purpose of this study is to analyze the risks that often occur in making credit cards. And provide efficient solutions. In solving this problem, it is necessary to apply the method. The method used in this study is Nearest Neighbor. The Nearest Neighbor algorithm is an approach to finding cases by calculating the proximity between new cases (testing data) and old cases (training data), which is based on matching the weights of a number of existing features. Therefore, it can be applied in analyzing old customer data with data new so that comparisons can be made whether or not it is eligible to receive credit. The results obtained in this study are the results of testing systems and methods by producing a level of risk.

Abstract

Anxiety is a normal reaction to stress and can be beneficial in some situations. It can alert us to dangers and help us prepare and pay attention. Anxiety disorders differ from normal feelings of nervousness or anxiousness and involve excessive fear or anxiety. Anxiety disorders can cause people to try to avoid situations that trigger or worsen their symptoms. There are several types of anxiety disorders, including Obsessive-Compulsive Disorder. Obsessive-Compulsive Disorder (OCD) is a disorder in which people have recurring, unwanted thoughts, ideas, or sensations (obsessions) that make them feel driven to do something repetitively (compulsions). Repetitive behaviors, such as hand washing, checking on things, or cleaning, can significantly interfere with a person’s daily activities and social interactions. This Expert system which implements Dempster Shafer Method can help anyone to make sure that they have OCD and need psychologist help to prevent this distress from becoming worst.

Abstract

Has designed a tool that serves to maintain the plant to grow well. Plants that grow well in need of treatment were quite good, especially in maintaining soil moisture. So that the land remains under inert conditions in accordance with the standard requirements necessary plants enough water. For that need attention regularly for watering plants. The automatic Plant Watering prototype uses temperature sensors and inertial-based Microcontroller Arduino Uno can be used in the treatment plant without the need to set watering schedules. In order for watering is not carried out during the day or during the scorching sun, the temperature sensor is used. Arduino microcontroller pin which has 14 digital input/output, which serves as the center of the brain process or the automatic sprinklers. The system was designed using a motor driver to drive the motor to pump water watering. Watering can prototype uses temperature sensors and inertial-based microcontroller Arduino Uno to move in automation tools for soil moisture has not been reached. If the soil moisture has been reached then the pump will stop watering the plants.

Abstract

Fiction books are one of the most popular books in Indonesia. There are five most popular genres in fiction books, namely fantasy, mystery, romance, sci-fi, and thriller. Each genre gives a different impression and its own fans for the reader. It is common practice when people choose fiction books based on the title, author, or publisher of the book. However, this does not provide precise search results. In this final project, an application system was developed to find out fiction books based on the semantic impressions contained on the cover of the fiction book. The impression on each book cover is obtained through a survey of fiction book lovers in Indonesia. To get the results of the proximity between the user search and the impression survey data obtained through text mining, as well as the cosine similarity algorithm to calculate the most precise proximity value to the impression expected by the user. The results of this system display fiction books that have the most precise proximity value to the impression expected by the user.

Abstract

One way to protect the copyright and authenticity of a digital image is to affix a watermark in the form of writing or a sign on the image. If the affixed watermark is visible, then its presence can interfere with the appearance of the image and it is possible that the watermark will be cut, discarded, or cropped by parties who are not entitled to do so. In this paper, an application is designed to affix a watermark in the form of an invisible message, or an invisible watermark by using a combination of pixel value indicator and the Most Significant Bit (MSB) method on the image, so that it is not detected visually and the visual appearance of the image is not disturbed. The message is scrambled using a key, then the scrambled bits are hidden in the 5th bit MSB and the 6th bit of the green channel or blue channel, depending on the number of bits 1 owned by the red channel which serves as an indicator. The process of hiding the watermark is carried out in the middle area of ​​the image, so it is difficult to cut to remove it. Applications designed can be used to affix an invisible watermark in the form of messages that are not easily removed on digital images, so that they can protect the copyright of a digital image.

Abstract

The development of computer technology both in software and hardware is very fast. These two aspects are interrelated with each other and cannot be separated. LTSP, Linux Terminal Server Project is a project started by James A McQuillan as a diskless networking project based on the GNU/Linux operating system. Called a diskless network, because the client is not equipped with a hard disk. All application software and operating systems needed by the client computer are served and managed by the server computer. In this design, a laptop with an Intel processor is used as a server and a PC as a client. LTSP will be integrated into the Linux operating system ubuntu 16.04, and as a provider of diskless thin client service platforms is LTSP (Linux Terminal Server Project). With LTSP, the construction of a diskless network is expected to be more efficient. Diskless network technology is one solution that can be applied in dealing with the problem of investing in computer technology hardware with predetermined specifications.
