Abstract

Generally, musical instrument learning is done face-to-face, with a teacher providing examples and later instruction from students follows. Many people want to learn the piano because the piano is able to express itself, one of which is for choir or personal pleasure. When someone plays the piano without any instruction from a teacher or someone who is an expert in playing the piano, they tend to use the wrong technique and posture in playing the instrument. Augmented Reality (AR) technology  has been widely used to facilitate the learning of new skills. In this study, it proposes a comparative analysis of applications that have applied Augmented Reality  technology using testing scenarios and using  the User Experience Questionnaire (UEQ) method. In this study, data collection was carried out by comparing  the Perfect  Piano application and the Skoove: Learn Piano  application using questionnaires. The questionnaire was distributed offline with a target of 10 respondents then divided into 2 groups based on the application to be studied. The results of this study show that the Perfect Piano application  has a value of 5.43 which is higher than  the Skoove: Learn Piano application.  This shows that  the Perfect Piano  application is easier for someone to use to learn the piano. This research is expected to be used to facilitate future research, especially to create an application that is more interactive and can be used as a means to facilitate musical instrument learning.

Abstract

Harga emas harian cenderung fluktuatif dan dipengaruhi oleh berbagai faktor eksternal yang tidak pasti. Penelitian ini bertujuan untuk meningkatkan akurasi peramalan harga emas harian. Metode yang digunakan adalah Fuzzy C-Means untuk clustering dan Fuzzy Time Series untuk prediksi. Fuzzy C-Means digunakan untuk mengelompokkan data harga emas berdasarkan pola fluktuasi yang serupa, sementara Fuzzy Time Series diterapkan untuk memprediksi harga masa depan dalam setiap kelompok. Data harga emas harian selama periode tertentu digunakan untuk membangun model. Hasil penelitian menunjukkan bahwa kombinasi Fuzzy C-Means dan Fuzzy Time Series dapat memberikan peramalan yang lebih akurat dibandingkan metode tradisional. Model ini berhasil menangani ketidakpastian harga dan mengidentifikasi pola yang lebih halus dalam data harga emas. Secara keseluruhan, metode ini efektif dalam meningkatkan prediksi harga emas di pasar yang sangat dinamis. Hal tersebut sesuai dengan hasil evaluasi model menggunakan MAPE dan RMSE. Nilai MAPE sebesar 1.92% yang menunjukan bahwa model akurat. Hasil RMSE sebesar 2.25% menunjukan bahwa model yang digunakan akurat. Penelitian ini memberikan kontribusi dalam pengembangan model peramalan harga emas yang lebih robust dan tepat.

Abstract

Company XYZ is a company engaged in the sale of electronic goods in Purworejo. XYZ company was founded in around 1990 and is one of the oldest existing companies in Purworejo. Currently, it is known that the business processes in the xyz company are still carried out manually. Starting from the process of ordering goods, selling goods, and making reports is still done manually and this company has not used an Application or Information System. This makes it difficult for companies to recap expense reports every month and difficulty in finding data that is needed quickly. Based on these problems, it is necessary to have an application or information system that can be used to facilitate the business processes of xyz companies. To facilitate the creation of applications or information systems, an architectural design is needed. In this study, the company's architectural design will use the TOGAF ADM Architecture, where TOGAF ADM has a framework that can be used to design, evaluate, and build the architecture of a company. The results of this study are in the form of an architectural design that can be used to support business processes and make a recap of expenditure reports at xyz companies.

Abstract

Procurement of goods in Indonesia continues to experience rapid growth. In 2022, the Indonesian government has allocated a budget of Rp. 2,714 trillion to fulfill government spending. Procurement of goods is almost carried out every month, to meet office needs and support operational facilities. Document storage is one of the important things in every company, however, until now there is no mobile application that can help archiving documents online. This is a problem where files are created and stored manually, so it is still difficult to find files and in transparating data. From the existing problems, there needs to be an innovation that can facilitate the process of managing and storing matching files. One of the innovations was carried out by designing a mobile application using the Design Thinking method. The Design Thinking method can be used to solve problems by rearranging problems into user perspectives that produce design ideas. The results of this study are in the form of a procurement mobile application design. It is hoped that the design and development of the mobile application will be able to provide convenience for Company XYZ in storing procurement documents. So that procurement can be done appropriately, effectively, efficiently, and the procurement documentation process can be carried out quickly.
