Abstract

The number of requests for freight forwarding services has increased every year. This increase in demand was triggered by the escalation of online shopping trends. As a result, many packages need to be managed in the warehouse. For this, an autonomous distribution system is needed in the warehouse so that warehouse management efficiency occurs, especially in time and labor. The system consists of a sensor encoder, IMU GY-521, RPLIDAR A1, and Robot Operating System (ROS). Systems with robotic characteristics like this can be classified as a type of autonomous mobile robot (AMR). The specialty of the research is the application of the hoverboard as a robot propulsion system. The local spatial map creation process is carried out by the Hector SLAM algorithm. Global and local path planning was created using the Navfn algorithm and the Dynamic Window Approach (DWA). For localization and finding the robot's current location, the Extended Kalman Filter (EKF) and Adaptive Monte Carlo Localization (AMCL) algorithms are used. The test results show that the hoverboard can be used in the system as a propulsion system with the ability to carry a maximum weight of 40Kg. The performance of the odometry, IMU, and RPLIDAR sensors get a sensor accuracy count of 99.61%, 81.93%, and 99.84%. For map making, the results obtained accuracy of 80% success using the Hector SLAM algorithm. Unhindered global navigation test achieves 80% accuracy. While local navigation with moving obstacles reaches 80% accuracy.

Abstract

The Indonesian Robot Contest (KRI) 2021 with one of its divisions, the Indonesian Robot Search and Rescue Contest (KRSRI), raised the background on the disaster environment with robots as a solution. There are obstacles on the path of the robot labyrinth as a manifestation of the irregularity of the disaster environment, using the obstacle board. A hexapod robot is a legged robot that can move if a certain movement pattern is applied with mathematical calculations such as inverse and body kinematic. The addition of a body kinematic, instead of inverse kinematics only, allows the robot to not only move sideways, forward and backward, but the addition of rotating motion is also possible. The hexapod robot is very possible to apply gait so that the robot can walk, three of which are tripod, wave, and ripple gait. Even though the robot is designed in such a way, there is still the possibility that there will be an error value during movement due to the imperfection of the system. The solution to reducing this value can be the application of a Proportional, Integral, and Derivative (PID) control system on the system. While the PID gain value can be found using the Zeigler-Nichols method which looks for the sustained oscillation signal from the system. On the yaw axis of the robot, the PID sustain oscillation values ​​are 1,23s, 2,1, for the pitch and roll axes of the robot to maintain balance, the sustain oscillation values ​​are 0,51s, 1,1, while the roll 1,72Hz, 1,2. The results of the robot's walking accuracy after using PID have increased, the tripod step pattern has an MAE (Mean Absolute Error) of 0,62, different from before the PID was implemented at 9,35. Wave and Ripple were previously unable to reach the finish line, with PID robots being able to reach the finish line.

Abstract

OSPFv3 and IS-IS routing protocols are routing protocols that are included in the type of link state routing protocol. In determining the best path, each routing protocol has different characteristics and algorithms. These differences will have an impact on how the work and results are different from the two routing protocols. This study used docker containers to simulate networks and implement routing protocols OSPFv3 and IS-IS with a hybrid topology. Both routing protocols will be implemented using IPv6 addressing. Testing will be carried out using 9 routers. The parameters to be used are the convergence time when the link is disconnected and the convergence time when the link reconnects. This study aims to determine the process of convergence when the link is broken and the process of convergence when the link is returned. This study showed that the OSPFv3 routing protocol has a faster convergence time than IS-IS in finding alternative paths when a link disconnection occurs. In 10 tests, OSPFv3 resulted in an average convergence time of 2046.55 ms compared to IS-IS whose average convergence time was 3686.74 ms. When linking back, the convergence value of IS-IS was faster with an average of 1843.08 ms compared to OSPFv3 with its average convergence time of 3891.16 ms.

Abstract

One of the main causes of infant mortality is associated with an increase in the Neonatal Mortality Rate (AKN) with low birth weight (LBW). LBW needs to be identified and predicted to prevent death when knowing the risk of LBW. In this study, a classification system was built as the initial identification of LBW. The data used comes from medical record data for childbirth at the Ardimulyo Public Health Center, Malang Regency for the January-August 2021 period in the form of imbalanced class. In this study, the method used is the Support Vector Machine (SVM) by combining the Synthetic Minority Oversampling Technique (SMOTE) technique. The performance of the SVM method without the SMOTE technique and the SVM method with the SMOTE technique using a linear kernel and RBF are compared in this study. Tests were carried out using 3-fold cross validation on kernel and parameter testing to find the best method and independent data testing of all methods. to compare the two. Based on testing the evaluation results obtained are less than optimal because they get low results. By testing the 3-fold cross validation test, the best results are obtained on the RBF kernel with the parameter lamda of 0.1, gamma of 0.001, complexity of 20, maximum iteration of 100, and epsilon of 0.001. Meanwhile, the results of data testing show that the best method is the RBF kernel SVM method without using SMOTE, which results in accuracy of 0.75, precision of 0.5, recall of 0.2, and f-measure of 0.2857.

Abstract

Due to the Covid-19 pandemic, the government has implemented restrictions with various policies, one of which is social distancing. The implementation of this policy changes people's habits, including in shopping activities, which must now pay attention to the distance limits set by the government, while people must interact directly with other people, which is very high risk. This research aims to design a self-checkout application user experience in supermarkets to help overcome the limitation problem, so that people can do shopping activities without worrying if they have to interact with other people. Self-checkout is a facility that allows users to pay and pack their own groceries without the help of a cashier. This facility is very easy to use because users only need to scan shopping items, then pack and pay for them on the provided machine. Human centered design method is used in this research. This method has several stages, namely literature study, usage context analysis, user needs analysis, solution design design, solution design evaluation, result analysis and drawing conclusions. The design of this application produces visual designs in the form of wireframes, mockups, and prototypes. The test results with the help of Maze and Google Forms get an effectiveness aspect value of 94.29%, an efficiency aspect of 0.200 goals per second, and a user satisfaction aspect of 85.25 with an excelent adjective rating and grade A.
