<![CDATA[Data security is important in the implementation of information technology, especially in the field of computers, which allows thousands of people and computers around the world to be connected in a virtual world known as cyberspace or the internet. This can create new challenges and demands for the availability of a data security system that is as sophisticated as the advances in computer technology itself. In cryptography, data sent over the network will be disguised in such a way that even if the data can be read by third parties, it should not be understood by unauthorized parties. Data to be sent and has not been encrypted which produces ChipperTtext. The implementation of the transposition algorithm for securing data flowing in the Local Area Network (LAN), the transposition process changes the arrangement of letters from the source text (plaintext), with a column transposition cipher, to obtain the words in a barred manner. In the transposition cipher, the plaintext is the same, but the sequence is changed. . This algorithm transposes a series of characters in the text. Another name for this method is permutation because transpose each character in the text is the same as permutating the characters so that this application generates encrypted data on the network stream and returns it to plaintext at the final destination. So that it can be ensured that the information and data sent to other parties are safe from unauthorized parties.]]>

<![CDATA[Quality of Service (QoS) on Live Streaming has the main parameters, namely bandwidth, jitter, loss and delay, which are measured on the implementation of Wireless IP Camera based on Android Smartphone. The test tools used iperf and ping software, to capture data packets. The network design in this study uses Xonz Wireless IP Camera, wifi router, Server/Laptop and Android Smartphone to monitor or access the services provided. Surveillance/reconnaissance or surveillance by accessing live streaming can be done from anywhere as long as there is still an intranet network. wifi router provides DHCP service, Server/Laptop provides a Virtual Machine using MS Windows Server 2003 Operating System. Web Server is not installed on Real Machine but on Virtual Machine. The smartphone used has the Android Operating System version 4.4.2. IP Camera Xonz model XZ-12Z-HR/W has one major drawback that it can only be accessed via Internet Explorer Browser which can only run on MS Windows Operating System. Some applications that are already available on Google Play and installed on Android Smartphones cannot detect the Wireless IP Camera. The outcome or impact of this research is the creation of a simple Live Streaming application that can be accessed by all browsers on all platforms including Android Smartphones. Measurements were made using iperf and ping. The results showed that the Xonz IP Camera can still be used for mobile room monitoring as far as a maximum of about 20 m from the wifi router and still meets the standard QoS values ​​set by TIPHON and ITU-T G.114.]]>

<![CDATA[The key to success in achieving the company's vision and mission is not only determined by the availability of technology and the availability of materials owned by the company. However, the potential of human resources is one of the capital that plays an important role in achieving company goals. However, the productivity of human resources can decrease due to various influencing factors. In addition to individual factors that come from the employees themselves, the excessive workload is a factor that can cause a decrease in employee productivity. Therefore, employees need to get good treatment in terms of the division of working hours, so that employees can work more optimally. The division of work shifts is one solution that can be carried out by the company. The problem with the existing leave application system at PT. Medan Sugar Industry is still done manually. Checking the remaining leave, submitting leave, and leaving approval are carried out in stages and still relies on the left card contained in each employee file data. With the Scheduling and Submission System for employee leave using the Genetic Algorithm Method at PT. Medan Sugar Industry, the employee scheduling process can be computerized and more effective.]]>

<![CDATA[Anorexia Nervosa (AN) is an eating disorder by making yourself feel hungry (self-starvation). Usually occurs in young women who are stepping on the high school bench (General High School). Their goal is to make themselves hungry so that they have a slim physical appearance and attract the attention of the opposite sex. There are 2 types of Anorexia Nervosa, Restrictive Anorexia Nervosa, people with this type of anorexia greatly limit the amount of food they consume, in fact they often do not eat at all until their bodies become very thin. Anorexia Nervosa Binge-purge, this type of anorexia is almost the same as bulimia. People who suffer from this disorder will eat in large quantities. But after eating, they will tend to feel guilty and then force to vomit back the food they ate. Mahoni Mental Hospital is one of the agencies engaged in health services, as a health agency, it is a must for the agency to improve its services both in terms of speed and timeliness. Mahoni Mental Hospital does not yet have a computerized system or method used to diagnose Anorexia Nervosa. Therefore, there is often a delay in the treatment of anorexia nervosa disorders. This study aims to build an expert system that functions as a tool for the Mahogany Mental Hospital or medical (experts) and medical students in diagnosing Anorexia Nervosa disorders. This study uses the Dempster Shafer method, in diagnosing Anorexia Nervosa disorder, based on the symptoms felt by the patient, then the results of the consultation are how many percent of the patient is affected by Restrictive Anorexia Nervosa or what percentage of the patient is Anorexia Nervosa Bingepurge]]>

<![CDATA[Class imbalance has become an ongoing problem in the field of Machine Learning and Classification. The group of data classes that are less known as the minority group, the other data class group is called the majority group (majority). In essence real data, data that is mined directly from the database is unbalanced. This condition makes it difficult for the classification method to perform generalization functions in the machine learning process. Almost all classification algorithms such as Naive Bayes, Decision Tree, K-Nearest Neighbor and others show very poor performance when working on data with highly unbalanced classes. The classification methods mentioned above are not equipped with the ability to deal with class imbalance problems. Many data processing methods are often used in cases of data imbalance, in this case research will be carried out using the Spider2 method. In this study, the Ecoli dataset was used, while for this study, 5 (five) different Ecoli datasets were used for each dataset for the level of data imbalance. After testing datasets with different levels of Inbalancing Ratio (IR), starting from the smallest 1.86 to 15.80, the results that explain that the KNN algorithm can improve its performance even better in terms of unbalanced data classification by adding the SPIDER- method 2 as a tool in dataset processing. In the 5 trials, the performance of the KNN algorithm can increase GM by 5.81% and FM 14.47% by adding the SPIDER-2 method to KNN.]]>
