Abstract

Under conditions that determine whether an apple is good or not, the human eye tends to have a subjective perception due to the color composition factor. Errors often occur because it is done manually. Therefore we need a tool with a system that can choose apples automatically based on their type. So we need a system that can identify the ripeness of apples by implementing SSD-Mobilenet. The purpose of this research is to identify the types of apples using SSD-MobileNet. From the results of the analysis and testing it can be concluded that the test results on data testing with lots of data, namely 50 datasets taken randomly produce an accuracy of 82% and an error of 18%. The number of errors indicates that the classification results are not completely accurate. This can happen due to the lack of training data so that only a few dominant terms are used, causing errors in course costs. However, the results of this accuracy can be used as a reference that assistance using SSD-Mobilenet provides a high value of 82%. So this method can be used to analyze the ripeness of apples.

Abstract

The application of lecture method as a teaching approach has been proven to be one of the factors contributing to low student grades. This is because the lecture method still revolves around the teacher as the primary source of information without actively involving the students. To address this issue, the solution is to implement Project Based Learning as a teaching method. This research utilized a quasi-experimental design. The population of this study consisted of X TKJ class students. Samples were selected using purposive sampling technique, with X TKJ 1 as the experimental group and X TKJ 2 as the control group. Data collection was conducted through tests and observations. Data analysis was performed using t-test and standardized gain test. Based on the research findings, there was a significant improvement in learning outcomes in the experimental group, with an increase of 78.74 categorized as high. Meanwhile, the control group showed a lower improvement in learning outcomes, with an increase of 28.33 categorized as low. Therefore, it can be concluded that students in X TKJ class, who were taught Jaringan Dasar subject using the Project Based Learning method with Cisco Packet Tracer as the media, exhibited higher improvement in learning outcomes compared to students taught with the lecture method.

Abstract

The implementation of the Learning Vector Quantization (LVQ) algorithm on smart barcodes aims to enhance efficiency and accuracy in recognizing and tracking product data. In this context, barcodes serve as visual representations containing crucial product information. The LVQ algorithm is employed to optimize the classification and matching processes of barcode data with precise references. Through repeated training, this algorithm adapts learning vectors to better recognize barcode variations. In this study, researchers analyze the impact of LVQ algorithm implementation on smart barcode systems concerning identification accuracy, computational efficiency, and adaptability to changes. Experimental results demonstrate the significant benefits of applying barcodes to inventory systems in overall stock management and business efficiency. By utilizing barcode technology, the processes of tracking and recording product data become faster, more accurate, and automated. Barcode usage minimizes human errors, optimizes time, and reduces operational costs. By combining the intelligence of the LVQ algorithm with the potential of barcodes, this research illustrates a crucial advancement in the technology integration domain for the development of more sophisticated and effective systems

Abstract

The current era's development directs us to understand data security better. Vital documents such as family cards often become subjects of forgery. Therefore, we must be capable of safeguarding the confidentiality of our data. This issue can be addressed through watermarking methods. Watermarking is a technique that can be used to embed information into an image. A digital image represents a machine-captured approximation of an image based on sampling and quantization. The image utilized here employs QR Code, which represents the evolution of one-dimensional barcodes into two-dimensional forms. This study employs the Discrete Cosine Transform (DCT) algorithm. This algorithm converts data from spatial form by segmenting images into sub-parts with varying frequencies. The application of the Discrete Cosine Transform (DCT) method in watermarking the QR Code on birth certificates has significantly contributed to the security and authentication of the document. Throughout this implementation, DCT has proven to be an effective tool for embedding additional information into birth certificate images without compromising the integrity of the main information. However, it should be noted that the use of DCT can also impact the visual quality of the image. Thus, parameter adjustments are necessary to strike the right balance between security and visual aesthetics.
