Abstract

Labuan Bajo is one of the popular tourist destinations in Indonesia. With the significant growth in the number of tourists, the need for homestays or local accommodation is increasing. However, tourists often have difficulty finding a homestay that suits their preferences, both in terms of price,facilities or location. This research aims to develop an Android-based homestay application that can help tourists find a homestay that suits their preferences. This application was developed using prototyping and modeling methods. The research results show that an Androidbased homestay application can help tourists find a homestay that suits their preferences. This application has features such as searching for the nearest homestay, rating filters, prices and desired facilities. This application can be a solution for tourists who want to find a homestay that suits their needs. This application can also help homestay managers to promote their homestays to tourists.

Abstract

Color plays a crucial role in visual applications such as object recognition, image processing, computer vision, and computer graphics. Support Vector Machine (SVM) algorithms have gained attention for color classification due to their ability to handle complex data. SVM, a machine learning algorithm for classification and regression, aims to find optimal decision boundaries. In color classification using SVM, color data is represented by feature vectors, and SVM learns patterns to classify colors accurately. The SVM algorithm demonstrates a high accuracy rate, with an average accuracy of approximately 85% in color detection. This indicates the SVM's ability to effectively separate and classify colors with precision. SVM is proven to be effective in handling non-linear color data by utilizing kernel functions to transform the feature space into higher dimensions, enabling accurate classification of complex color data. The outstanding performance of the SVM algorithm in color detection presents vast potential applications in color recognition, image processing, computer vision, and computer graphics. SVM offers accurate and reliable solutions for object classification based on color characteristics in various contexts.

Abstract

Accurate sales to improve business planning and decision making. This study aims to design an information system that utilizes historical data and multiple linear regression algorithms to predict e-commerce sales. This study addresses the current challenges in forecasting uncertain sales by analyzing historical sales data and identifying relevant independent variables, such as marketing efforts, economic factors, and customer behavior. Through the implementation of a multiple linear regression algorithm, the system calculates the relationship between these variables and sales, enabling accurate predictions. The proposed information system provides valuable insights for businesses to optimize inventory management, marketing strategy and resource allocation. The experimental results show the effectiveness of the system in forecasting e-commerce sales, resulting in increased operational efficiency and revenue. This research contributes to the field of e-commerce analytics and assists businesses in making data-driven decisions for sustainable growth.

Abstract

Publications are activities that disseminate research through scientific journals in the form of articles. Publication data management in the Informatics Study Program at Udayana University is still conducted using Google Forms. This method has limitations, such as restricted features, suboptimal design, and lack of efficient data history access. The proposed solution is a web-based system that improves publication data management, from data collection to publication monitoring. It is expected to overcome Google Form’s limitations and increase data management efficiency. The system involves two user types students and admins. Students can log in, view information, upload files, check review results, make revisions, and update file status. Admins can log in to add, edit, delete information, and record the review results of student files.

Abstract

Aplikasi Gianyarku Aman adalah sistem informasi yang dirancang untuk meningkatkan akses dan efisiensilayanan kesehatan di Kabupaten Gianyar, khususnya dalam hal pengelolaan informasi kesehatan, antreanpasien, dan jadwal layanan medis. Sistem ini bertujuan untuk memberikan akses cepat, akurat, dan terstrukturterhadap informasi penting seperti jadwal dokter, ketersediaan tempat tidur, dan fasilitas kesehatan terdekat,serta mempermudah proses pengambilan dan pemantauan antrean. Dalam program pengabdian di DinasKesehatan Kabupaten Gianyar, mahasiswa yang menjalani Praktik Kerja Lapangan (PKL) diarahkan untukmenyusun Dokumen SRS (Software Requirement Specification) untuk aplikasi Gianyarku Aman. DokumenSRS ini berfungsi sebagai panduan terperinci bagi pengembang perangkat lunak, yang mencakup spesifikasifungsional dan non-fungsional, serta skenario penggunaan (use cases) yang menggambarkan interaksipengguna dalam sistem. Penyusunan dokumen SRS ini sangat penting untuk memastikan aplikasi dapatberfungsi sesuai dengan kebutuhan masyarakat dan standar layanan kesehatan di Kabupaten Gianyar, sertamempermudah pemeliharaan dan pengembangan sistem di masa depan. Dengan panduan ini, pengembangdapat memastikan aplikasi Gianyarku Aman dapat diimplementasikan secara optimal untuk mendukungkualitas pelayanan dan aksesibilitas layanan kesehatan.
