Abstract

ARP(Address Resolution Protocol) is a protocol to translate an IP address into MAC address. ARP is used when a host wants to communicate with another hosts whose MAC address is unknown, it broadcast an ARP request packet for the hardware address associated with the IP address of a destination. The host with corresponding protocol address sends a unicast reply to the sender. Protocol ARP is a stateless protocol which caused ARP protocol has a vulnerability. ARP vulnerability support a network attack called ARP Spoofing attack or ARP cache poisoned attack. ARP Spoofing attack perform cache poisoning by sending spoofed ARP packet. ARP spoofing is capable of executing the other attack such as DOS attack, Man in the middle attack, host impersonating, etc. This research was conducted to detect ARP Spoofing attack using based on ARP packet traffic. ARP packet traffic will be checked by detector host. Detector host checks the header of packet, amount of packet, MAC duplication and ARP request of ARP reply packet. The information of ARP spoofing packet will be written on log file. The classification rate was 89.64% and the average time to detect the attack is 0.4 second.

Abstract

In Indonesia domestic rice production and rice imports are needed in order to attain national rice consumption. As the number of people increases and imported rice are consumed continuously, therefore Indonesia depends on rice imports from other countries. Prediction is needed to control the volume of national rice imports because excessive imports will cause negative losses and impacts. Support Vector Regression (SVR) is used to predict the volume of national rice imports. The data used in the prediction are data on consumption, production, volume of rice imports 1 year earlier as bebas variables and data on the volume of national rice imports in the period 1971 - 2016 as terikat variables. Tests carried out using 9 test data obtained the best parameters Sigma (σ) = 0.07, Lambda (λ) = 0.4, Constanta Learning Rate (cLr) = 0.01, Kompleksitas (C) = 10, Epsilon (ε) = 0.0004, the number of Iterations = 2000 and the number of training data = 37. The evaluation results were measured using Mean Absolute Presentage Error (MAPE). The best MAPE value produced is included in the sufficient category of 32.2748

Abstract

Process of letter managing and dispositioning in PT PGAS Solution is not effective and takes a long time. This condition causing various problems such as wrong recipients of dispositions, the recipient who is not in the office, late implementation, has no report, and often loss disposition sheet that has been distributed. Therefore, a website-based system is established where the required engineering needs a total of 23 functional requirements and 1 non-functional requirement. These needs are designed and implemented through an object-oriented approach, using Ruby on Rails (RoR). RoR was chosen because this framework builds websites by abstracting and simplifying the most repetitive tasks. Rails and most of its libraries are also open sources. In white-box testing carried out through unit testing and integration testing, the value of the cyclomatic complexity calculation obtained from each test case is between 1-10. In the validation test, a test of 35 test cases was carried out with the conclusion that the system can run well. Then in compatibility testing, the system successfully runs on 4 different browsers without any fatal errors. Through this development, a system which can facilitate the management of the letter and its dissociation process is produced.

Abstract

Indonesia is a country that has a great diversity of cultures and natural wealth. One of Indonesia's natural wealth that is the attraction of the world is its tourist attractions. The beauty of tourist attractions in Indonesia makes Indonesia becomes a country that is often visited by foreign tourists on vacation. Tourism is one business that can increase economic growth. Tourists visit is increased sigficantly due to many factors, including competitive travel costs, promotion strategies that continue to be intensified, and many adequate travel routes. This must be balanced with adequate facilities and guaranteed security. The number of visitors that cannot be ascertained must be predictable in anticipation of sudden increases or deterioration, so that the state can determine policies towards changes in the number of visitors in the future. The method that will be used to predict in this study is the average-based fuzzy time series models and the using 216 data obtained from the official website of the Statistic Indonesia, it is data of the number of foreign tourist visits to Indonesia in the period January 1999 to December 2016. Based on the result of the study obtained MAPE value is 10,140%, that MAPE value is good to predict, because it is under 20%. So can be concluded that average-based fuzzy time series is good enough to predict the number of foreign tourists visit to Indonesia.

Abstract

Plagiarism is an inseparable thing from an academic environment. Various motivations including working part-time and social dilemmas contribute to the high percentage of plagiarism at the university level. Handling with the plagiarism detection method has many disadvantages, such as the emergence police-criminal paradigm, value-oriented mindset, and technical weakness such as inability in analyzing translated documents. Hellas, Leinonen, and Ihantola's research with the plagiarism prevention method has several shortcomings, namely ignoring the process of work so that students can be cheated by buying assignments, the analysis at the end makes students able to cheat during assignments, no any log produced so the teacher can't assess student effort, and the software is tied to a particular platform. This research aims to perfect previous research by adding a snapshotting process that records document changes, user activity logging which records student activities, and build the systems with agnostic properties so that there is freedom to choose the form of tasks and the software that will be used. The system is tested using unit testing, integration, validation, automated testing, and compatibility. Unit testing and integration are valid and exceed 70% code coverage, validation testing in 32 test cases are valid, and compatibility testing shows the system is running well on six common desktop environments. Valid automated testing that contains no errors can speed up the testing process.

Abstract

Economic growth in the information and communication sector in Indonesia continues to rise every year. This is driven by the number of internet users, for example online transactions. This positive growth has made changes spending patterns of Indonesian people increasingly shifting towards electronics or online shopping. Whereas Awesam sells products according to the wishes of the users still in the conventional way that makes customers have to come direclty to the store. The sales coverage is still small because it can only make sales in certain areas. The absence of customer-related database such as contacts, names and geographic information and purchase history makes a lack of service to customers. This certainly makes Awesam not able to compete in online sales. The solution to handle some of these problems is by developing a sales information system using Rational Unified Process (RUP) method based on Sales Force Automation (SFA). The final result of this research is a sales information system to assist the Awesam in handling each transaction, improve service to customers and face competition. Some tests carried out to maintain software quality including validation testing conducted to find out the functional system can run well which shows 100% valid, responsiveness testing to ensure the system can adapt to the size of the user's screen resolution shows that displays can adapt to 3 sizes of resolution properly. As well as compability testing to test non-functional requirements that indicate no errors have occurred.
