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

In 2010 - 2014 the agricultural sector occupied the first position in terms of non-oil and gas exports in Indonesia, it explained that the Indonesian agricultural sector greatly supports the country's economy. One of the results of the agricultural sector is coffee plants that have been recognized by the global market as evidenced by occupying the fourth position in international coffee exports. The number and quality of Indonesian coffee caused Indonesia's coffee exports to rank fourth after Brazil, Vietnam and Thailand. Because 90% of coffee farmers in Indonesia who play a role are small-scale farmers who have agricultural areas between 1-2 hectares and coffee requires temperatures between 20 ℃ - 28 ℃ and humidity between 50% - 70% so that the flavor and quality of coffee produced is satisfying. That is why Indonesian coffee production is not optimal because it lags behind in terms of good coffee processing and technology from other countries. Therefore, to help small-scale coffee farmers in terms of increasing the quality of coffee production, a temperature and humidity control system for coffee bean storage is made using Arduino UNO and the MQTT protocol. The purpose of this system is to detect changes in the temperature and humidity of the coffee bean storage warehouse if the condition exceeds the system parameter point by automatically stabilizing it so that it does not damage the quality of the coffee.

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

Traffic accident factors are caused by 3 factors such as human negligence, the state of the vehicle and also environmental factors. According to WHO (World Health Organization) the use of helmets for motorcycle riders can reduce the risk of death by up to 40%. The use of helmets as safety for motorcycle riders is still considered not so important that it is ignored, therefore motorcycle accidents, especially motorcyclists who do not use helmets and the level of traffic violations are high. The fatigue factor for the police in monitoring traffic causes ignoring motorists who violate by not wearing a helmet while driving. Therefore helmet detection for motorcycle riders is very important, namely using technology to obtain information on motorcycle riders who violate the rules. Based on these factors, after knowing the causes of motorcycle accidents in traffic, one solution can be reduced, namely using computer vision for helmet detection as motorcycle riders' safety in driving and facilitating the work of police officers in guarding traffic by way of notification. notification of traffic violations of motorists who are not wearing helmets with buzzer alerts. The author proposes the CNN (Convolutional Neural Network) method as a detection of motorcyclists who violate traffic such as not wearing a helmet, thereby reducing traffic accidents. The results of the tests that have been carried out by the system can detect objects of people not wearing helmets with an accuracy of 90% using the confusion matrix on the test results.

Abstract

Real Work Lecture (KKN) is an activity that cannot be separated from lecture activities and is a must for every student who attends a minimum of Bachelor's Degree (S.I) in higher education institutions. An important factor that can influence the success of KKN is the selection of villages for KKN. The villages available for KKN are located in community complexes with different development sectors, problems and environments. To help alleviate this problem, there is a platform that can help determine the location of KKN that is relevant to students. The StudyDesa application is based on Android and uses geotagging technology and camera sensors to help mapping KKN villages. This study uses the waterfall method, the method was chosen because the functional requirements that exist in the system have been defined clearly from the start and there are no changes. The tests of the StudyDesa application are functional, compatibility and usability testing. Functional testing is performed on all functionality and produces a value of 100%. Compatibility testing can run on all tested devices, namely the 3 most Android versions used by the Indonesian people in 2021. Usability testing produces a success rate of 94.28% while the System Usability Scale (SUS) produces an average value of 85.5 or if viewed on the conversion scale it is located in category B which means it is acceptable for students.

Abstract

SDN is a new paradigm in computer networks that separates the control plane and data plane. The concept offers better programmability of devices and more efficient network management. In the context of determining the route in the routing mechanism on the SDN network, topology discovery and routing calculations are carried out by the SDN controller only. The mechanism in determining the best route traversed by a packet from the sender to the receiver is determined by a routing algorithm. One of the existing routing algorithms is the link-state routing algorithm. One application of the existing link state routing algorithm is the Dijkstra algorithm. In Dijkstra's Algorithm the focus of this algorithm is only on the route search strategy without defining the weights used. In general, the static distance between two nodes will be weighted without considering the condition factor of the network being passed. Weights based on distance will result in the shortest route but may not be the most optimal. With the programmable SDN technology, weight optimization that considers network density can be implemented. Therefore, in this research, the implementation of Dijkstra's routing algorithm system for finding the shortest path has been carried out by paying attention to packet loss as a weight. From the test results, the results obtained that the system has been able to search for paths by considering the smallest packet loss value on the link. In throughput testing, the system has significantly superior throughput compared to static Dijkstra algorithm. Then based on packet loss testing, this system has packet loss ranging from 0 - 1% compared to Dijkstra's static algorithm which has a significant increase in packet loss when the number of clients is more than 30. In this system the convergence time value obtained is not much different from the static Dijkstra algorithm.
