Abstract

Current database technology makes it possible to store huge amounts of accumulated data but this is where the data explosion problem arises, for example at the University. Budi Darma University Medan is still analyzing data manually to determine the promotion strategy plan of the geographic distribution of students. The distribution of students can be done by grouping student data based on the similarity of the characteristics of the data using the clustering method with the dbscan algorithm. Making data mining applications aims to make it easier to analyze student distribution groupings. The data used is data from the 2018 to 2019 batch of students. In this study the application was built using Rapid Miner. This technique can determine clusters of irregular data shapes and can handle noise effectively. This research focuses on the implementation of the DBSCAN method in the process of grouping the distribution of student areas from the university as a promotion strategy for the Budi Darma University campus in the future. It is hoped that the system will be built in accordance with the expectations of researchers, so that it can classify the distribution of student areas from as a Budi Darma University campus promotion strategy.

Abstract

Vape is an electric cigarette that is widely used as a temporary escape for those who have a little difficulty in trying to quit smoking. Vape produces steam into the air which contains fine nicotine and other harmful substances, the nicotine contained in the vape will be absorbed by the body. The vapors that emerge from vape cigarettes are not water vapor, but they contain nicotine and other harmful substances that are clearly not good for health and can also pollute the air. Several studies have shown that chemicals in e-cigarettes can damage lung tissue and reduce the ability of lung cells to protect the lungs from germs and other harmful substances. ANFIS method is an adaptive system based on fuzzy logic inference that combines two methods, namely adaptive (neural metwork) and fuzzy methods. This adaptive network is used to adapt the fuzzy logic inference system to represent the desired fuzzy interference system. The principle of the working method is to combine two methods, namely the adaptive method and the fuzzy method where both use the same two sources of information, but the representation is different. The results of diagnosing vape-related diseases are lung infection, hypotension, and heart failure, but the disease that is often caused by vape is lung infection, with an expert system diagnosing vape-related diseases that make it easier to find out the effects of vape use.

Abstract

Remote sensing with high-resolution panchromatic imagery plays an important role in spatial analysis such as regional mapping, spatial planning, and disaster mitigation. One important stage in image processing is edge detection, which serves to clarify the boundaries of objects such as buildings, roads, and rivers. Problems that often arise in panchromatic images are noise, contrast differences, and spatial data complexity, which cause traditional edge detection methods to be less than optimal. This study proposes the use of the Homogeneity algorithm as a solution due to its simplicity in gradient calculation. This algorithm works by comparing the intensity value of the central pixel to its eight neighbours in a 3x3 kernel, then selecting the maximum difference to determine the presence of edges. The results of implementation on a 5x5 sample image show that large difference values represent edges, while small values indicate homogeneous areas. Further application on a 500x500 pixel panchromatic image produces clear and contrasting edge visualisation, allowing for better recognition of surface object boundaries. This study proves that the Homogeneity algorithm is capable of extracting image edges quickly and effectively, and can be used as an efficient alternative to complex convolution methods for real-time remote sensing applications.

Abstract

The Embedded Zero-Tree Wavelet (EZW) algorithm is a wavelet-based image compression method that offers high-efficiency progressive encoding through the use of a zero-tree structure to represent insignificant wavelet coefficients. This study designs and implements an EZW-based image compression application to address the main problem of image compression, which is finding a balance between a high compression ratio and image reconstruction quality that is still acceptable to the human visual system. The research stages included literature study, algorithm and interface design, program code implementation, and testing using various test images. The results showed that the EZW algorithm was able to achieve a compression ratio of between 87.90% and 93.13%. The compression results showed a significant reduction in file size. For example, an image sized 2311 KB could be compressed to 191 KB, while maintaining good visual quality based on the Peak Signal-to-Noise Ratio (PSNR) and visual evaluation. Compared to conventional methods such as JPEG and Discrete Cosine Transform (DCT), EZW proved to be superior in bandwidth efficiency and artefact reduction in images with high compression rates. This study also identified a research gap in computational efficiency and power consumption when the algorithm is applied to real-time systems, thus requiring further development in hardware optimisation and quantisation stage modification. Thus, this study confirms that EZW-based image compression applications can be an effective solution for digital image storage and transmission needs in environments with limited bandwidth and storage capacity.

Abstract

This study discusses the application of cryptography using the super-encryption method as a solution for securing student grade data at SMA Negeri 5 Medan, which still relies on manual systems and is therefore vulnerable to manipulation and data leakage. Super-encryption was chosen because it combines two cipher techniques to strengthen security, with the Vigenere Cipher algorithm employed as one of the methods for both encryption and decryption processes. The research stages include literature review, system requirements analysis, architecture and algorithm design, application implementation, testing, and result documentation. The encryption process successfully transformed the plaintext of student grades into ciphertext that is difficult for unauthorized parties to interpret, while the decryption process accurately restored the ciphertext to its original form using the same key. The testing results indicate that this method ensures the confidentiality and integrity of academic data while enhancing the security of multi-user information systems. Thus, this research emphasizes that implementing super-encryption in student grade management systems not only protects privacy and data authenticity but also serves as a strategic solution to address cybersecurity threats in the field of education.

Abstract

The development of technology and information through the internet is currently very rapid. The delivery of fast, accurate, and relevant information has become a basic need for companies to support operations and marketing strategies. Technological advances encourage companies to develop information systems that can facilitate the delivery and management of data efficiently. One solution is to design a web-based goods ordering system. This system is expected to provide convenience for companies in marketing products and presenting ordering information in real-time, transparent, and structured. This study was conducted at PT. Matahari Department Store Thamrin Plaza, where the previously used manual system was deemed ineffective in managing customer demand and inventory. In designing this system, the author used the PHP programming language and the phpMyAdmin application for database management, which was run through the XAMPP platform. Meanwhile, MySQL was used as a database to store all goods ordering information systematically. The development of this system was also designed with a user-friendly interface so that it can be easily used by internal company users. In addition, this system supports operational process efficiency, reduces the risk of errors in recording orders, and facilitates managerial decision-making based on available data. By implementing this web-based ordering system, the company is expected to improve the quality of customer service and obtain an information system tailored to its operational needs. If the system operates properly, it will provide added value to PT. Matahari Department Store Thamrin Plaza in terms of efficiency, speed, and accuracy of order processing.

Abstract

Every year the number of alumni from schools is increasing, especially at the secondary school level. To identify alumni from a school, a track record of the alumni is needed. However, there are still many schools that do not have a track record of their alumni so that many schools still do not know what their alumni do after graduating from school. Meanwhile, data and information related to alumni are very useful for schools for various purposes, one of which is for the process of improving school accreditation. One of them is the Mandiri Vocational High School (SMK). Therefore, a system is needed that can answer the school's need for information on its alumni. So a system called the alumni tracer study information system was created. The information system was made web-based using the Laravel framework and uses a MySQL database and modeling using the Unified Modeling Language (UML). The results of the creation of the alumni tracer study information system will greatly assist schools in the process of collecting data about alumni both in terms of time, accuracy and good results. This system can help in overcoming obstacles and barriers that exist at Mandiri SMK, especially those related to the alumni data collection process. This system will also facilitate the process of searching for alumni data and information when needed by the school.
