Abstract

SARS-CoV-2 virus, also known as COVID-19, has become a very deadly epidemic for the past 2 years. At the end of 2021, the world was threatened by the emergence of a new Covid-19 variant, namely omicron. This variant is referred to as one that is very fast in transmission. The virus was first detected in South Africa and was designated by the world health agency (WHO) as a variant of concern under the name B.1.1.529. This has made omicron a big topic of discussion throughout the world community until now. Social media have played a crucial role in spreading information about the variant of omicron throughout the world. Twitter is a microblogging social media platform that is very effective in sharing lots of information. The number of tweets uploaded every minute is very large, up to 350,000 tweets. This number can be a very useful source of data for obtaining a public opinion on certain topics, especially the covid-19 omicron-related tweets. Sentiment analysis plays an important role in this issue. By using the sentiment analysis method, these opinions can be classified into positive or negative opinions. The long-Short Term Memory algorithm is one of the methods used in classifying the sentiment of public opinion. Optimization of this model is done by using the Glove word embedding method. This method works by counting the occurrence of a word with another word and then converting it into a vector. The result of sentiment analysis using the Long-Short Term Memory and GloVe Embedding method with 100 dimensions resulted in an accuracy rate of 82%.

Abstract

COVID-19 (Coronavirus Disease 2019) is a new type of disease related to the same virus family as Severe Acute Respiratory Syndrome (SARS) and several strains of the common cold virus. Along with the increase of positive cases, the resources needed in handling COVID-19 cases also increase. To overcome this problem, anticipatory measures are needed so that the resources needed in handling COVID-19 such as health workers and medicines will be available before positive cases spike. In this study, the method used is the hybrid Autoregressive Integrated Moving Average (ARIMA) and Long Short-Term Memory (LSTM) method. The ARIMA-LSTM model is built by combining the ARIMA (2,1,2) model with the LSTM model which has 4 hidden states and 1 layer. ARIMA model is used to predict the trend value from time series data while LSTM model is used to complete the ARIMA model forecasting by predicting the time series residual value. Based on testing, the ARIMA-LSTM model achieved high accuracy, especially in short-term forecasting with an error rate of 1.8 percent for forecasting cases for the next 3 days.

Abstract

The Internet is growing rapidly, communication between internet users is also increasing from time to time around the world. The Internet today is customized by thousands of autonomous systems (AS) that exchange information and communicate using the Border Routing Protocol (BGP) protocol. BGP is a standard gateway routing protocol that is used to introduce to the public outside the network by peering and exchanging network information between US. BGP introduces to other networks with peering to all connected AS and who have been registered in the list of AS numbers. BGP is also responsible for the routing of that occurs between axles and also has an important role in routing. Routing data information can be seen in the RIB or can be called a routing table. Routing information in BGP is so complex and has an extensive network, it is not possible to collect and view routing data one by one. The disadvantage if you look at the data as above is if the BGP has many peers in the US and outside the US in the network. To facilitate the monitoring and evaluation of the BGP Network, a service is needed to monitor and evaluate the network, namely the visualization of BGP routing data. With the aim of saving time, effort and cost in maintaining the BGP network. This final project focuses on the process of how the network topology Border Routing Protocol (BGP) get the service that is by visualization based on data routing Border Routing Protocol (BGP). The network topology is applied to Docker and configured with FRRouting. Visualization is applied to the web interface with Laravel, Tailwind CSS and d3.js. Testing of the visualization system is done by validating the data against the data routing Border Routing Protocol (BGP) with the results of visualization, error testing of the visualization system and testing the best path to the visualization system by changing the route on the routing protocol Border Routing Protocol (BGP). The results obtained visualization system works well in accordance with the function and based on data routing Border Routing Protocol (BGP).

Abstract

Meeting management is a step to plan, organize, lead and control meetings that have been scheduled. Fakultas Ilmu Komputer (FILKOM) differentites the scope of the meeting into study program meetings, department meetings, faculty meetings and committee meetings. The stages of holding meetings in FILKOM are preparation, execution and accomplishment. The first stage in preparation is to determine the chairperson of the meeting. The meeting leader determines the topic, participants and schedule. Furthermore, the secretary helps determine the room for the meeting and contacts the participants. But there are obstacles because the meeting initiator has difficulty getting the schedule of participants and the secretary has difficulty choosing a meeting room because there is no meeting room schedule. The meeting management system at FILKOM was developed to address these problems. The system development uses the waterfall model with an object-oriented approach. Testing are carried out using unit testing, integration testing and validation testing. White-box testing is used in unit and integration tests. Blackbox testing is used in validation testing. The results of all tests are 100% valid.

Abstract

Mobile ad-hoc network (MANET) is a network that can function without a fixed infrastructure. In MANET, the communication process is managed using a mechanism called a routing protocol. In this case, a problem arises that generally can occur in MANET, namely network security problems. Wormhole itself is a network attack that cannot be carried out by one node, because basically a wormhole attack forms a tunnel that connects one wormhole node with other wormhole nodes. Therefore, this study evaluates the impact of wormhole attacks on the MANET network using the Location Aided Routing (LAR) routing protocol. From the results of the tests carried out, the effect of increasing the number of nodes in the network before the wormhole attack occurred to get the best value from the packet delivery ratio parameter of 97.13% for a variation of 40 nodes. For the average end to end delay parameter, the best value is obtained at a variation of 20 nodes with a value of 57.06ms. And the best value of the routine overhead parameter is obtained at a variation of 40 nodes with a value of 0.73. While in the scheme after the wormhole attack, the value of the packet delivery ratio parameter increased significantly, achieved at a variation of 30 nodes with a value of 99.92%. For the average end to end delay parameter, the best value is obtained at a variation of 30 nodes with a value of 41.62ms. And for the routine overhead parameter, the best value is obtained at a variation of 30 nodes with a value of 0.18..
