Abstract

Stock trading is a daily activity carried out by a stock trader. A stock trader can perform this trading activity on a capital market. In the capital market, you can see a chart that depicts the price movement of a stock in a certain period, also known as "Price Trend". The most important characteristic of a price trend is volatile and irregular changes in direction. Due to its volatile and irregular nature, a problem arises in knowing where the price trend will move. Any mistake in predicting the direction of the trend can cause losses. This study implements the random forest algorithm as a solution model, and technical analysis as a predictive feature to minimize errors in predicting future stock price trends. Based on the test results, the combination of the random forest algorithm and technical analysis is able to minimize errors in predicting price trends with an accuracy of 84% and an f1 score of 88%.

Abstract

Wireless Sensor Networks used to collect all of data and information in complex environments. WSN uses wireless communication channel technology to transmit data, without security protection, data is very vulnerable to internal and external attacks. Black hole is one of the attacks that occur on WSN. A black hole attack works by declaring itself to have the shortest route to the destination node. This is very dangerous if the package contains important information. From these problems, black hole attacks can be detected using the Support Vector Machine method on the Ad Hoc On-Demand Distance Vector reactive protocol. SVM is a powerful method for classification and regression. The purpose of this study is to determine the accuracy of SVM in detecting black hole attacks and how much data is discarded by these malicious nodes. In the test results, it can be seen when the simulation is under normal conditions, the packet loss is small (1), while in the simulation there are black holes (239) 100%. Simulation with normal conditions on the packet delivery ratio as much as 99,5816%, while the simulation has a black hole with a value of 0%. Simulations with normal conditions have an average end-to-end delay of 202,429 ms, while in the simulation there are black holes of about 172,524 ms to 214,979 ms. The results showed that the SVM algorithm in classifying black hole attacks with calculations produced accurate results.

Abstract

In an educational institution, a forum is absolutely needed where the academic community severely provides suggestions and criticisms about what they feel about the educational institution facilities such as a forum for criticism and suggestions provided by Brawijaya University, namely e-complaint. E-complaint is a facility managed by the campus as a means of accommodating suggestions, criticisms, opinions from users regarding services or facilities provided by the campus. However, the e-complaint facility is currently considered to be less than optimal because the criticism or suggestions submitted by the academic community are not processed quickly by the parties concerned. This is because the e-complaint manager sorts the documents manually which causes a long time process and the e-complaint manager does not sort the documents based on importance and urgency so that the process of solving the e-complaint's problem is not sorted by the priority of the urgency. Therefore, a system is needed that can classify campus e-complaint documents based on their level of importance and urgency. In this study, a text pre-processing process was carried out, which was then carried out using the BM25 method as a ranking method and the K-Nearest Neighbor method as a classification method. Based on the test results using k-fold cross validation, the highest average value of precision is 1, recall value is 0,46875, f-measure value is 0,6875.

Abstract

Indonesian people have the right to obtain information about health, this is written in Undang-undang number 36 of 2009 chapter III article 7. Meanwhile, the government has an obligation to provide access to information, education, and health service facilities as stated in article 14 chapter 4 Undang-undang number 36 of 2009. However, based on the facts on the ground when interviews were conducted with several people in the city of Malang, it can be concluded that the current system is still conventional and requires improvements in the process of delivering information. The Malang city government innovates by applying the Smart City concept to solve this problem. The realization that was carried out was the development of an Android-based mobile application called Malang Sehat which was divided into 3 modules, namely the Health Data Collection and Monitoring module, the Health Services module and the last one that became the topic of this research was the Health Service Object Information module. This module was built using the Prototyping method with 5 process stages, namely communication, quick plan, quick design modeling, construction of prototype, and prototype delivery and feedback. The loop iteration will stop if the stakeholders state that the application has met the needs when providing feedback. After the iteration process is complete and the prototype has been declared to meet the needs, then the Functional, Usability, and Compatibility testing is carried out. On Functional testing produces a 100% success rate. Furthermore, the Usability test which was tested on 10 respondents resulted in a success rate of 98.57% and the final score of the System Usability Scale (SUS) reaching 84.75% with an adjective rating of "Good". Finally, the Compatibility test only concluded that the system can run well on a minimum version of Android 5 with API level 21.
