Abstract

Salinity is the key parameters in the shrimp culture environment. Conventional method is by visiting each pond plot. But,due to the large number and distance between the plots, this method is less effective. This ineffectiveness can lead to less than optimal yields. Manet is applied to increase the effectiveness of checking salinity using the BATMAN routing protocol. In this study, 2 units of laptops were used that act as Node 1 and Node 4, 2 units of Orange Pi Zero as Node 2, and 3. Each device is connected to a conductivity sensor to measure the salinity. The four devices are configured with an adhoc network using the BATMAN routing protocol. This research was conducted to provide an alternative for monitoring salinity to make it more effective. Based on the results of testing and analysis of network quality, the average delay value is 22.285 ms. The low delay value affects the percentage of packet loss in the four test scenarios with an average percentage of 0.999759613 %. Memory and CPU usage in testing 4 transition scenarios resulted in an average memory usage of 0.225% and CPU usage of 0.725%. The BATMAN routing protocol does not use a lot of memory and CPU usage because it only forwards data packets without the need to process data. From these data, it can be concluded that manet with batman routing protocol can be used as an alternative communication to provide communication network services in areas where there is no fixed network infrastructure.

Abstract

The library is one of the rooms or facilities used as a learning center. Data on library visitors with a locker at the Polinema library is in a different place, where the Polinema library locker are outside the library area which can be misused for storage of public goods. Visitors only enter the library area to ask for locker keys and leave items in the lockers, but visitors do not visit the library. To overcome this, a system was designed using a QR Code scan that can be used as a library visitor data system that can directly open the locker door using an OTP code, after getting the OTP code visitors can enter items and then lock them automatically. Application login testing can be done according to the system. Testing of open/closed locker markers and admins can access the locker if someone leaves the Library area. The coordinates of the GPS points for 4 visitors who came out of the Library area with a distance of 25,049m, 38,839m, 56,502m, and 64,904m were proven with a maximum distance of 20m. Comparison of the distance between Formula Haversine and Google Maps (distance between 2 points) obtained an accuracy rate of 0.236%.

Abstract

Catfish is one of the results of freshwater cultivation that is popular with the community and has economic value. The high public interest in catfish, is one of the factors cultivators increase production yields. Feeding and treatment of catfish pond water still uses human resources. This reduces the efficiency of the farmer and allows for negligence in providing feed and water treatment if the farmer has a large number of ponds or more than one. In this study, it is proposed to control and monitor feeding and water treatment with a biofloc system automatically and regularly, with the catfish biofloc system also obtaining natural food when the feeding schedule is raining. It takes a wireless sensor network system as a control system, fc-37 sensor, Total Dissolved Solids (TDS), Loadcell, Real Time Clock (RTC). All of these sensors will be integrated with the Arduino Uno which will then send data from each sensor to the Raspberry Pi with the nRF24l01 communication module. The results of this study are monitoring the appearance of the web server processed by the Raspberry Pi which shows feed availability, pond conditions and turbidity levels. From the experimental results, it is found that the planned system can work well and as desired.

Abstract

The gate is the most important component of a building's security system. Although almost all homes have gates, they are still opened and closed in the traditional manner. As technology advances, a remote control may be used to automatically open and close the gate. In this study, the author attempts to develop a gate utilizing an internet-connected microcontroller and an android smartphone application to make it simpler for users to manage and monitor the motor's status and eliminate the need for a remote control. The automatic gate prototype includes a track length of 3 meters, a 12 V dc gearbox motor, and a control system. The gate load standard is 15.40 kg. The study's findings employ the Internet of Things (IoT) to regulate and observe gate opening and closing as well as gather data on gate status and maintenance. According to test results, an average torque value of 78.44 Nm at an average current value of 10.25 A was obtained utilizing a mass load variation between 1 and 15 kg. Qos performance between Node MCU and Android application shows the quality of data transfer during deceleration with an average value of 34.3 seconds. The average throughput value is 149.6719 bps.

Abstract

Wedding decorations are considered incomplete without decoration. The decoration business must prepare a skilled and creative workforce and improve the artistic creation skills of employees to provide several choices of decorating styles to clients. The material that was recently used in decorations is styrofoam. The purpose of this research is to design a CNC machine to get good results and neatly cut Styrofoam using a hot wire. This research also contributes to solving problems with Styrofoam cutting usually a problem with detailed and complicated work that can be solved automatically using a CNC machine. Tool hardware design requires Bluetooth connection, driver to the stepper motor, driver A4988 to CNC shield, and step down to the heating wire. Software design includes uploading GRBL firmware, creating G-code using Inkscape Software, and connecting Android applications to CNC machines. The result shows that for 2-dimensional styrofoam cutting with 1cm thickness, the best results are obtained in the range voltage of 7.4-8.5V. Styrofoam also testing is carried out using the same voltage 8.5V but with different feed rates and the result with 400 mm/min shows the best cut performance. The results of cutting 3-dimensional Styrofoam showed that for a voltage of 8.5V, a feed rate of 300mm/min, and a thickness of 10cm Styrofoam produced the best cutting texture from others. This shows that the heat generated by the wire is directly proportional to the feed rate

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
