Abstract

Advances in information technology are currently driving the growth of the number of internet users. In the business world, the role of technology is very important, and it can be said that it has become a primary need for entrepreneurs at this time. Likewise about culinary, knowledge about this needs to be taken and judged properly digitally such as from the aspect of place, taste, presentation and price. So that later it can be given to the community and passed down from generation to generation as well as to promote to foreign tourists so that they can be better known and increase the country's foreign exchange. The use of ontology as an information representation technique is the preferred solution in this case because ontology can be used to improve the development of semantic applications, especially when dealing with the semantic web. The method of building the ontology model used is Methodology. This method is one method of building an ontology model that can reuse the built ontology for further system development. The development of the ontology model in this study uses an application called Protégé and in the evaluation process, the ontology gives good results in answering the questions given by the users.

Abstract

Information systems play a crucial role in facilitating business processes, including in the scrap recycling industry. In this context, this research aims to develop an information system that enables efficient management of the procurement process of scrap materials from suppliers. The User Centered Design (UCD) method is adopted to ensure that the developed system truly meets the needs and preferences of users. The system implementation is carried out using web-based technologies with PHP and MySQL as the database backend. End users, including scrap material suppliers, can access the system through a responsive web interface. System evaluation is conducted using the Single Ease Question (SEQ) and System Usability Scale (SUS) methods to measure user responses and system usability. The development results show that the scrap material supplier information system has been successfully developed. Users responded positively to the user-friendly interface and provided functionality. The testing involved 10 respondents, yielding a SEQ score calculation of 88%, indicating success. Additionally, SUS testing resulted in a high satisfaction level of 87.25% among users regarding system usability. Thus, this research contributes to the development of information systems that integrate UCD principles to support efficiency and effectiveness in managing scrap material suppliers in the recycling industry.

Abstract

Plagiarism in the music industry is a serious issue that requires advanced solutions. This research proposes a Machine Learning-based system for detecting song plagiarism by combining Convolutional Neural Network (CNN) and Dynamic Time Warping (DTW). CNN is used to extract features from the visual representation of music notations, while DTW measures the temporal distance between two sequences of notations. Experimental results show that this system provides a more accurate solution with an accuracy of 92.71%, with a dataset of 4800 data points. Keywords: Music plagiarism, Convolutional Neural Network (CNN), Dynamic Time Warping (DTW), plagiarism detection, music notation, machine learning

Abstract

Distributor merupakan suatu kelompok usaha yang melakukan distribusi penyaluran produk ke suatu tempat ke tempat lain. Saluran distribusi sangat dipengaruhi faktor jalur pengiriman barang yang efisien sehingga bisa menghemat waktu dan biaya. Namun tidak jarang distributor mengalami kendala saat melakukan pengantaran barang, seperti waktu perjalanan yang terlalu lama dan bingung memilih tujuan mana yang terlebih dahulu dikunjungi. Salah satu penyebabnya karena luasnya wilayah yang harus ditempuh. Penyebab lainnya disebabkan karena banyaknya jalan raya terlebih lagi volume kendaraan yang banyak sering kali menyulitkan seseorang untuk mencari jalur terpendek ke tempat tujuan yang terdekat, baik dari segi jarak maupun waktu tempuh. Dari ranah bidang ilmu Informatika, penentuan rute distributor ini termasuk ke dalam permasalahan Travelling Salesman Problem. Permasalahan TSP dapat diselesaikan menggunakan beberapa algoritma, salah satunya adalah algoritma A Star. Algoritma A Star adalah salah satu algoritma pencarian graf dengan menggunakan fungsi jarak-plus-biaya untuk menentukan urutan titik yang akan dikunjungi. Dalam permasalahan ini yang harus dipecahkan adalah bagaimana cara agar bisa mengunjungi tempat yang dituju dengan jarak, waktu dan biaya yang minimum. Pada penelitian ini menggunakan data primer berupa 17 titik toko yang sudah ditentukan di wilayah kota Denpasar berupa lokasi sebagai vertex dan jarak antar toko.

Abstract

The speed and efficiency of a system at this time has a very important role. Currently there are several solutions to answer these challenges, one of which is to separate the database on the system. In this study, an analysis was carried out on the separation of databases on a transactional and analytic system. Analysis is carried out with a research flow that begins with problem identification followed by sampling data on technology companies that have transactional systems, then implementing transactional and analytical programs on microservices architecture, conducting tests with Load-Testing, followed by analysis of test results and then drawing conclusions. After conducting research in accordance with the research flow, it was concluded that the separation of databases on transactional and analytic systems is better for producing faster system performance compared to transactional and analytic systems using the same database.

Abstract

Public complaints are an important mechanism in maintaining accountability of the government and other organizations, as well as strengthening relations between the government and citizens. Public complaints provide an opportunity for individuals or groups to report problems, dissatisfaction, or violations they experience related to public services, corruption, human rights violations, and so on. However, in some cases in some areas it is still difficult to make complaints about the environment that occur in the community. Therefore, we have compiled this journal with the title "Website-based public complaint information system" to help the public in making complaints against local governments. The information system has of course become a very integral tool for human life, therefore the existence of a "website-based public complaint information system" can help the public easily. Keywords: Website, Public Complaints, Waterfall

Abstract

In Indonesia, people often call a restaurant as a warung. Similar to restaurants, warung also provide food and drinks that can be ordered by customers. Most warung in Indonesia still use employees to do work such as taking orders and doing calculations. When the queue exceeds the limit, employees will be overwhelmed and most of them will make mistakes both in recording orders and calculating prices. To minimize those errors, the authors designed a mobile-based user interface at Warung Jimbaloka that can record orders and calculate the total price for customers. The interface design that has been made will be analyzed using the System Usability Scale (SUS) method in order to measure user’s satisfaction. The result of this study indicate that the interface design of this system is X with a value of X.
