Abstract

Baraya Cargo is a shipping company that carries out shipping activities through a series of business process activities starting from contract agreements, shipping preparation, delivery, and ending with the issuance of invoices. The current business processes are still experiencing problems from time delays and the occurrence of a lack of documents that disrupt the performance of Baraya Cargo. Therefore, improvement activities were carried out starting from modeling the main business processes in the form of Business Process Model and Notation (BPMN) in the Bizagi application. The business process model is then evaluated using the Quality Evaluation Framework (QEF). It was found that there are 3 main business processes that have problems where there are inappropriate metric values. After that, an analysis was carried out using Root Cause Analysis (RCA) to find the root cause of the metrics that did not match. Recommendations are then given using streaming tools from Business Process Improvement (BPI). Finally, a simulation was carried out through the Bizagi application to determine the time performance improvement between business processes (as-is) and business processes (to-be). The simulation results show that the contract agreement business process has increased performance by 75.5%, the delivery business process is 1.6% and the invoice issuance business process is 76.5%. It can be seen that the implementation of the recommended business process shows a significant performance improvement when applied to Baraya Cargo.

Abstract

The isolation room in the hospital has very strict safety and health procedures to maintain the sterility of the area. This requires health workers to use personal protective equipment (PPE) during their activities in the isolation room. The virus outbreak in 2020 made hospitals need more isolation rooms, resulting in higher demand for PPE supplies and a higher risk of health workers being exposed to the virus. For this, an autonomous mobile robot system is needed at the hospital to help the workforce, especially in terms of logistics. The system consists of several components including Kinect sensor, encoder, IMU, and with Robot Operating System (ROS) middleware. The advantage of this research is the shape of the robot prototype which has a large size. To create autonomous navigation, a path planning method is needed, therefore the Timed Elastic Band (TEB) algorithm is used. Before navigating, a precise map is needed, therefore a map-making method using the GMapping algorithm is needed. The test results on navigation show an accuracy of 50% from 10 trials that have been successful 5 times. Navigation is carried out using the TEB algorithm computation time of 2.77 seconds and the average time of successful robot movement to the destination coordinates is 129.98 seconds. For mapping, the accuracy is 50% with map size accuracy of 98.84%.

Abstract

Current technological developments make it easier for humans to explore a lot of information using the internet such as review information or opinions about films. Public opinion about the film can be found on the IMDB website. By doing a sentiment analysis on public opinion about the film, we can conclude whether a film gets more positive or negative opinions. To perform this sentiment analysis, one of the deep learning methods is used, namely Long Short-Term Memory (LSTM) with FastText as a vector representation of words in the IMDB movie reviews dataset of 50,000 data. Performance using the Long Short-Term Memory and FastText methods produces an accuracy of 0.863; precision of 0.865; recalls of 0.861; and f1-score of 0.863. This LSTM and FastText method produces better performance than using LSTM alone with a difference of 0.053 on the f1-score value with details of accuracy reaching 0.808; precision reaches 0.804; recalls reached 0.816; f1-score reaches 0.810 for the LSTM method only.

Abstract

Long Range (LoRa) is one of IoT technology used in a system that require long distance communication and in a need of low cost system. Delivering a packet on LoRa takes time depending on the distance to the destination, the farther the distance, the longer delivery time will take. This makes LoRa network security while delivering packet, vulnerable to attacks. This research analyze packet delivery on LoRa using the AODV routing protocol and the impact of Wormhole attack lon the AODV routing protocol on LoRa. This study uses 3 LoRa nodes and 1 malicous wormhole node. The analysis is reviewed with QoS paramers, namely Troughput, Delay, Jitter, and Packet Loss. The result of the test show that Wormhole attack affects the performance of packet delivery in LoRa. In the non-attack scenario, the average Delay value is 0.171s, Packet Loss is 0%, the average of Troughput is 408,321 kbps, and the average of Jitter is 0.0003ms. In the Wormhole attack scenario, the average Delay values is increased to 0.343s, Packet Loss increased to 70%, Troughput decreases by an average of 204,105 kbps and Jitter increases by an average of 0.05724ms. It can be concluded that Wormhole attack on the AODV routing protocol affects the qualiy of QoS on the delivery of each packet.

Abstract

Monitoring system is a system that aims to monitor activities on network devices. Monitoring is needed to monitor any problems that have the potential indication to disrupt the internet network. A method that can be used to monitor the network is to use the Elastic Stack. In this final project, Elastic Stack will be applied to monitor network traffic by providing a visualization of the existing network traffic data and then analyzing the traffic data. The main component of this system is a server in which the Elastic Stack components have been configured, there are Packetbeat, Elasticsearch and Kibana. The process for visualizing and analyzing network traffic begins with data collection, data transmission, data processing and data visualization on the dashboard. In the data collection process, the data used is sample data from network traffic at Brawijaya University which is obtained using TCPdump. Next, the sample data will be sent to Elasticsearch by Packetbeat to be stored in the database and indexed. The indexed data will be grouped then into certain fields to indicate what information is contained in the sample data. In these fields, visualizations in the form of pies, charts and graphs will be displayed on the Kibana Dashboard based on data stored.

Abstract

Cooking oil is one of the basic needs of the Indonesian people for food processing ingredients, especially for frying process. Palm cooking oil is commonly used by Indonesian people because it matches the Indonesian people's taste. In its use, cooking oil is often used repeatedly for savings which is known as used cooking oil. The use of used cooking oil can increase the risk of several diseases for the body, such as carcinoma and diarrhea caused by the accumulation of peroxide values, as well as changes in the color and clarity of the oil. To determine the quality of the oil, the method used today is to test the peroxide number in the laboratory. However, this method takes more time and is not cheap. So that a system was created that can detect the quality of cooking oil based on color and clarity using the Naive Bayes method to shorten the time at a lower price. This study uses a TCS3200 sensor to detect color changes, and an LDR sensor to detect oil clarity. There are 2 classes used, namely the Eligible class to declare that the oil is still suitable for use and the Inappropriate class to declare that the oil is not suitable for use. In the research results, the accuracy of the TCS3200 sensor is 95.15%, the accuracy of the Naive Bayes method is 87,5%, and the overall system accuracy is 87.5%.
