Abstract

Konsumsi daging di Indonesia didominasi oleh sapi, kerbau, dan ayam. Namun, beberapa pedagang nakal mencampur daging sapi dengan daging babi sehingga sulit dibedakan oleh masyarakat awam. Beberapa penelitian telah menggunakan metode Convolutional Neural Network (CNN) untuk mengklasifikasikan citra, namun kekurangan data menjadi tantangan. Oleh karena itu, penelitian ini menerapkan teknik augmentasi data pada model CNN Alexnet untuk mengklasifikasikan daging sapi, babi, dan daging oplosan. Penelitian ini menggunakan dua rasio pembagian data yang berbeda, yaitu 90:10 dan 80:20, dengan total 600 data non-augmentasi dan 3000 data augmentasi yang dibagi menjadi tiga kelas. Beberapa hyperparameter diuji untuk mengoptimalkan kinerja model seperti optimizer Adaptive Moment Estimation (Adam), Stochastic Gradient Descent (SGD) dan Propagasi Root Mean Square (RMSprop) serta learning rate 0.1, 0.01, 0.001 dan 0.0001. Hasil menunjukkan bahwa penggunaan data citra augmentasi dengan optimizer Adam dan learning rate 0,001 memberikan accuracy tertinggi sebesar 85,00%. Sementara itu, penggunaan data citra non-augmentasi dengan skenario optimizer RMSprop dan learning rate 0, 0001 menghasilkan performa yang sedikit lebih rendah, yaitu mendapatkan accuracy 80.00%. Keduanya menggunakan perbandingan data 80:20. Teknik augmentasi data berhasil meningkatkan kinerja model deep learning dengan menciptakan data baru dari data yang ada.

Abstract

In cultivating fish using ponds, there are quite a number of parameters that must be considered in order to get the desired results and minimize failure in the cultivation of the fish itself. The problems that occur in fish farming according to the references obtained are the temperature and pH of the water that are not in accordance with the needs of the fish itself. Optimal water temperature conditions for intensive catfish maintenance are 25 – 30°C. Meanwhile, from time to time the temperature of the water can change due to certain factors. Based on the above problems, IoT technology is used which can identify and detect the data above, so that it can analyze the required data and automatic feeding with consistent time. Testing will be carried out by adjusting the data taken by the sensor used as well as the output from the tool itself by utilizing existing manual measuring instruments so that the data taken by the sensor itself is not in doubt the data taken by the sensor itself. Automatic temperature control devices and pool monitoring will be a solution to problems beyond human control. The tool will detect the pool temperature, if it feels like the pool water temperature needs to be warmed up, then the water will be channeled by a water pump to the heatsink attached to the cold side of the TEC, then the colder water will be put back into the pool, and vice versa when the pool water temperature feels cold. The monitoring system can make it easier for catfish breeders to monitor pond water conditions via mobile phones only with the web.

Abstract

This research aims to address the negative impact of less educational games by creating an interactive educational game for Android that combines learning about national flags and memorizing flag images, thus enhancing logical thinking skills in children. It is developed using the Flutter framework as the development platform and follows the GDLC method, with alpha testing conducted using the blackbox method. The Fisher-Yates Shuffle algorithm is implemented for shuffling the flag images and the order of elements in the card list. The testing method involves using the Debug Console in Visual Studio Code to verify the success of the shuffling process. The conducted testing, performed six times, demonstrates the algorithm's success in shuffling the card order for each level. In the easy level, the randomized order is 6, 10, 8, 5, 3, 4, 11, 2, 7, 1, 12, 9. In the normal level, the randomized order is 6, 11, 20, 16, 1, 13, 19, 17, 9, 2, 15, 4, 10, 12, 14, 8, 5, 7, 2, 18. In the hard level, the randomized order is 2, 14, 1, 21, 7, 18, 24, 22, 10, 23, 6, 11, 15, 9, 17, 4, 8, 3, 5, 13, 16, 12, 19, 20. The Fisher-Yates Shuffle algorithm successfully generates diverse shuffling of flag images and avoids repeating the random order of cards each time the game starts. Thus, this game can provide stimulation to the brain and encourage children to effectively enhance their object memory skills.

Abstract

This study aims to design and develop a vehicle plate detection system for refueling. Applications built using the K-Nearest Neighbor (KNN) method, this method is used to classify vehicle plates. This research will use the OpenCV module in the python programming language to recognize vehicle plates and carry out the pre-processing, segmentation, feature extraction, and classification stages of vehicle Image data. This system will utilize the K-Nearest Neighbor (KNN) method such as edge detection, perspective transformation, and pattern recognition to achieve optimal results. The test results show that the system is able to recognize with high accuracy various types of vehicle license plates under different lighting conditions and viewing angles, thus a system can be created and determined for each license plate to only be refueled once a day. When the vehicle has never been filled on that day, the system will display a green light which means refueling can be done. Whereas for vehicles that have filled in on that day, the system will display a red light which means the vehicle cannot fill up so it must wait the next day after the system is reset. This system will be able to accurately and real-time detect and identify the vehicle plates used in the refueling process. Therefore, the design of this system is expected to be the basis for increasing efficiency in the refueling industry as well as providing a basis for the development of further research in this field.

Abstract

For some people, having a pet can relieve stress or fatigue. There are also people who raise animals to supplement their income. Animals such as cats, cows and goats are animals that are often found in settlements and areas. Usually these animals are released in apartments. Of course, once released, the owner will no longer be able to control his pet. That's why we need a device to control these pets. Based on the above information, it is necessary to have technology that is focused on surveillance systems. This technology uses surveillance devices based on the Internet of Things (IoT). The task of the monitoring device is to retrieve and collect data from the environment being measured. There are main components such as Arduino Nano 328P, NodeMCU ESP8266, LoRa, Ublox NEO-6M Gps and Android. This system has two tools, a transmitter and a receiver. First, the transmitter sets up a TET connection. When the connection is stable, the base station's GPS recovers local information in the form of longitude and latitude. After the data is successfully retrieved, the data is stored and the location is sent to the recipient (LoRa). After receiving the data (LoRa), the receiver will set up the connection first, when the connection is stable, the data received from the transmitter will be sent to the server and displayed on the App. The tool works well at a maximum distance of ±35 meters and if the tool works at a distance of 25-35 meters the coordinate point is still legible but not accurate. If the tool works more than 40 meters then the coordinates will not be read at all. The distance and position of the transmitter can affect the results on the display in the Blynk application and the coordinate points on the Arduino.
