Abstract

Dalam pemerintahan, pelayanan publik merupakan salah satu sektor yang penting. Hal itu dikarenakan kualitas dari sebuah pemerintahan dapat dilihat dari kualitas pelayanan publik. Di zaman sekarang peran internet sangat penting sehingga kualitas konektivitas jaringan menjadi sangat penting. Di Denpasar terdapat banyak OPD (Organisasi Perangkat Daerah) yang terkoneksi ke server pusat Kota Denpasar, sehingga perlu sebuah system untuk memantau kualitas dari masing-masing OPD. Pada system ini selain dapat memantau kondisi jaringan dari masing-masing OPD juga dapat menambahkan serta mengupdate profil dari OPD tersebut. Sistem ini diharapkan dapat membantu petugas khususnya petugas jaringan dalam memantau kondisi jaringa di masing-masing OPD serta dapat melakukan tindakan sesegera mungkin apabila terjadi gangguan jaringan berdasarkan sIstem monitoring tersebut.

Abstract

The security of gym member data files is an important aspect of maintaining the privacy and security of personal information stored in the gym management system. In this study, we propose the application of the Advanced Encryption Standard (AES) algorithm as a solution to secure gym member data files. AES is an encryption algorithm known for its high security and has been extensively used in information security applications. In this implementation, each gym member's data files, such as profiles, addresses, and other personal information, will be encrypted using a secret key that only the system knows. With encryption using AES, even if the member's data file is stolen or accessed illegally, the information contained in it remains safe and cannot be read without the correct secret key. The results of the trial found that this application succeeded in encrypting some member data files with .pdf format into the. rda format, then decrypting them back into the original file form without changing the original file size. So, it can be shown that the use of the AES algorithm in securing gym member data files provides a high level of security and protects sensitive information from unauthorized parties.

This study focuses on analyzing the User Interface (UI) of the Kisahnesia application using the System Usability Scale (SUS) methodology. The objective of the study is to assess the usability of the application and determine the level of user satisfaction. The SUS questionnaire was administered to a sample of users, and based on the analysis of the collected data, the application obtained a score of 78.375. This score indicates that the Kisahnesia application has passed the usability test, demonstrating a high level of usability and user satisfaction. The findings suggest that the UI design of Kisahnesia is effective in providing a user-friendly and intuitive experience, contributing to the overall positive user perception of the application's usability.

Abstract

Indonesia has islands that are inhabited by more than 255 million people, making Indonesia the fourth most populous country in the world. Not far from the population density in Indonesia, there are various kinds of culture, one of which is by showing the identity of each region by wearing their traditional clothes. Traditional clothing in various regions in Indonesia certainly has different uses and meanings and has its own characteristics, so it needs to be studied properly. The appropriate method for documenting Traditional Clothing is with an appropriate onological knowledge base to present the information. In this project, ontology methods are created using the Protege ontology developer tool. We apply the METHONTOLOGY method in the development of the ontology model, which describes in detail each step taken. The designed ontology model has 21 classes, 5 object properties, 2 data properties, and 32 individuals. We focus on explaining which materials, ethnicities and origins are used in Traditional Clothing. Testing is carried out using the ontology model development by performing a SPARQL query.

Abstract

Balinese Gamelan, a traditional ensemble music from Bali, Indonesia, encompasses a rich cultural heritage. However, organizing and classifying its diverse musical compositions pose significant challenges. In this study, we propose an ontology-based semantic web approach for organizing and classifying Balinese Gamelan music. We develop an ontology that captures the hierarchical and relational structure of Gamelan music elements. Leveraging semantic web technologies, particularly RDF (Resource Description Framework) and SPARQL (SPARQL Protocol and RDF Query Language), we create a knowledge base that represents the ontology and facilitates efficient data retrieval and classification. Our approach provides a systematic and comprehensive framework for organizing and accessing Balinese Gamelan music information, offering a valuable resource for musicologists, researchers, and enthusiasts.

Abstract

In the face of escalating security challenges in the advanced digital era, the exchange and storage of video files have become integral to daily life, impacting everything from business communication to personal entertainment. While the internet facilitates easy access to multimedia content, it also brings heightened risks of data theft and privacy breaches. Cryptography offers a solution by encrypting sensitive data. This research employs two encryption algorithms, Salsa20 and RSA, to protect video files. Salsa20 ensures fast and secure encryption, maintaining data integrity and confidentiality. RSA facilitates secure key exchange, limiting access to authorized recipients. The combined use of these algorithms effectively secures video files, guarding against data theft and privacy breaches. This offline encryption system offers flexible accessibility without compromising security. Additionally, it preserves the original file extension, adding an extra layer of protection, while decryption enables seamless access and playback of video content.

Abstract

Despite the increasing importance of data security in safeguarding sensitive information, this study addresses the potential risks associated with unauthorized access to critical data. Employing the ChaCha20-Poly1305 algorithm, the research focuses on implementing encryption and decryption processes for Small and Medium Enterprise (SME) documents, supplemented by key derivation from AES-256 for enhanced security. A nonce Initialization Vector (IV) is generated using the ChaCha20-Poly1305 algorithm, with users inputting secret keys for encryption. The system then encrypts the data using the ChaCha-Poly1305 algorithm and derives keys from AES using SHA-256 hashing. For decryption, users input the encrypted document into the program, along with the previously used key. The system design employs a simple web-based application, with the ChaCha20-Poly1305 cryptography algorithm implemented in PHP. The study successfully tests the ChaCha20-Poly1305 algorithm, and the program exhibits secure decryption processes, evidenced by consistent byte sizes of tested SME documents.

Abstract

In an increasingly advanced digital era, the demand for recommendation systems that can provide products that match user preferences is increasingly high. The method used in this research is User-Based Collaborative Filtering, an approach that utilizes the purchasing patterns of other users to provide recommendations to active users. The research process began with collecting transaction datasets and product user preferences from leading e-commerce platforms. This data is then processed through the loading, preprocessing and analysis stages to prepare good data. Model performance is carried out using Mean Absolute Error (MAE) through a 5-fold cross validation process. The evaluation results show that the model has a satisfactory level of accuracy, with an average MAE value of 0.31. This research contributes to the development of a product recommendation system that can help improve users' online shopping experience by providing relevant and personalized recommendations.
