Abstract

This research discusses the design and implementation of wireless communication using WISE-4051-AE for optimizing process-level practical modules. The WISE-4051-AE wireless device is an integrated IoT (Internet of Things) device that combines data acquisition, processing, and control functionalities. Continuing previous research, this study focuses on creating practical modules for process control, including flow meter calibration, cascade control, feedforward control, and ratio control. By utilizing the WISE-4051-AE wireless device in a plant setting, the processed data can be accessed through laptops, personal computers, and other devices that support communication with the WISE-4051-AE device. To get the data, a device must be connected to the WISE-4051-AE wireless device. By employing the WISE-4051-AE wireless device for data transmission, users of the process-level practical modules can receive real-time plant data, regardless of whether the modules are indoors or outdoors, without encountering any data alteration during the transmission process. In this research, the WISE-4051-AE wireless device has a maximum range limitation. As long as the user's device remains within the signal range of the WISE-4051-AE device, the transmitted data will not undergo any changes. The signal range was tested under two conditions: without signal obstacles and with signal obstacles. The results of the signal range testing revealed a maximum range of 90 meters without obstacles and 40 meters with obstacles.

Abstract

The increasing reliance on online communication and data storage has made protecting sensitive information a top priority for businesses and individuals. This study investigates the effectiveness of different security protocols in safeguarding databases from external threats. By comparing the performance of databases that use SSL and those that do not, this project provided valuable insights into the importance of securing data in transit and the impact of security protocols on database performance. The results of this research could be helpful for companies and individuals looking to improve the security of their databases and protect sensitive information. These research findings demonstrate that enabling SSL encryption leads to longer average execution times for database operations. This latency can be attributed to the computational workload associated with SSL's encryption and decryption processes. However, the trade-off between performance and security is essential to safeguarding data in transit.

Abstract

The COVID-19 pandemic has prompted changes in teaching methods from offline to online, including the implementation of exams. But many reports say that the potential for online exam cheating is very high which can compromise the credibility of the exam. The online exam monitoring system using one camera makes it difficult for officers to make decisions because of the lack of evidence and supporting data. In this study, we propose a monitoring approach using two cameras, namely a camera on a laptop to get a front view of the participant and a cellphone camera to get a side view of the examinee but because of the complexity of the problem, at this stage we only focus on the side camera. Implementation begins with the collection of video recording data, custom data sets for training and pretrained datasets from the zoo model. Training is carried out using a custom dataset to detect objects that are not recognized by the pretrained dataset. The evaluation of the training results using the COCO evaluator showed the average of the bbox-AP is 59,169. The fraud detection process is carried out using 6 exam videos with a total of 192,929 frames, producing two outputs, namely object detection videos and csv files. The csv file contains the frame number, time, object detected in each frame. The next process is to analyze the csv file and mark frames that have the potential to be fraudulent. The evaluation results show an accuracy of 0.884615385 and a recall of 0.821428571

Abstract

Tourism development is the impact of changes in tourist interest in tourist destinations. The growing interest in tourism travel that wants to nature, interact, and learn the uniqueness of culture. Tourism Village is a form of integration between accommodation and supporting facilities presented in a community life structure that integrates with the rules and traditions that apply. To increase tourism potential in the Tourism Village promotion is required to attract travellers. Generally, traveller want to travel to the Tourism Village must come directly to the location to place an order. Therefore, we need an application regarding the information on Tourism Villages in Banyuwangi and ordering Android-based tour packages to bridge between visitors and Tourism Village managers. The application development method uses the waterfall framework by analyzing system design needs and testing. Application developed using a java-based programming language for the Android platform supported by the Android SDK and Android Studio as the development environment. This application aims to make it easier for the public and potential visitors to get information about Tourism Villages and to be able to order tour packages online. This application also makes it easier for Tourism Village managers to promote managed Tourism Villages

Abstract

Ultrasonic welding workload on vertical roller welding components on face-mask body machine in making masks has a highvibration of up to 20kHz. This high vibration causes the locking bolt to loosen the serrations, thus causing a greater failure of function, such as wear and tear on the teeth. If this function fails, it will cause downtime and high costs in the waiting process for the cleat component to be remanufactured. The damage prognosis system based on the condition of this machine implements a Classification of types of damage along with recommendations for maintenance activities that need to be carried out on the Face-Mask Body Machine. Classification of the type of damage to this system using There is a Belief-Backpropagation Neural Network (BPNN), a method for looking for weight settings on a neural network based on the error rate obtained in the previous iteration. This method is optimized using AdaBelief, which can adapt the step size based on the "confidence" of the previous gradient to get Convergence rates and generalization abilities better so that these types of problems can be known from the vibration signal of the machine which previously the signal was parsed using wavelet packet decomposition into frequency bands to obtain component data with low or high frequency. From the results of system performance testing, the modeling accuracy is 98.4%, so this system can be declared good and feasible to use in slack detection of vertical roller welding cleat fixing bolts.
