This advancement revolutionizes the way we access information, especially about various processed fish dishes in Indonesia. However, despite the plethora of culinary offerings, travelers often find it difficult to discover traditional dishes through social media platforms. To bridge this gap, a new app that utilizes artificial neural networks has been developed. The app allows users to photograph and upload images of processed fish dishes to recognize and provide detailed descriptions and recipes. In addition, integrating Google Maps makes it easy for users to find nearby places that serve these dishes. Testing the app with a dataset consisting of 1577 images of six types of processed fish dishes yielded promising results, with accuracy reaching 97.57% over 120 epochs. This innovation not only preserves cultural heritage but also enhances the culinary experience for locals and tourists.</p> 2024-04-30T00:00:00+00:00 Copyright (c) 2024 Rachmad Saptono, Abdul Rasyid, Waluyo Waluyo, Farida Arinie Soelistianto https://wsj.westscience-press.com/index.php/wsist/article/view/846 The Influence of Attractions, Accessibility, and Facilities on The Image of The Peak Batu Roti Ciampea Tourism Object 2024-04-30T04:23:32+00:00 Padri Achyarsyah padri.achyarsyah@unas.ac.id Rizki Nurul Nugraha rizki.nurul@civitas.unas.ac.id Dipa Teruna Awaloedin Dipa.Teruna.Awaloedin@unas.ac.id <div><span lang="EN-US">Puncak Batu Roti is a tourist attraction in Bogor Regency. The lack of diversity in tourist attractions causes fluctuations in the number of tourist visits. This title was chosen because Batu Roti Peak Ciampea is the specific location that wants to be researched, and this research tries to understand the factors that can influence the image of tourist attractions at that location. Batu Roti Peak is located on the Ciampea Limestone Mountain, Bogor. This peak is one of five peaks in the area, which also include Galau Peak, Lalana Peak, Arca Lima Peak, and Karang Gantung Peak. The location is about 17 km from the center of Bogor City. This research aims to see how tourist attractions (x) influence visiting interest (y) at the Puncak Batu Roti Tourist Attraction. Tourists who come to the Puncak Batu Roti Tourist Attraction are the objects of this research. Quantitative descriptive data analysis was used in this research. Data collected from the questionnaire was used for simple linear regression analysis. The research results show that the tourist attraction variable is in the good category with a percentage of 68.33% and the interest in visiting variable is also in the good category with a percentage of 2%. This result has a significant positive value, indicating that the more tourist attractions there are at the Puncak Batu Roti Tourist Attraction, the greater the interest in visiting. Researchers advise managers to develop new tourist attractions such as limestone educational tourism for elementary, middle and high school students by utilizing the property of local residents in the Puncak area. They also suggested building a Tourist Information Center (TIC) to provide information about all aspects of the Puncak Batu Roti Tourist Attraction for tourists.</span></div> 2024-04-30T00:00:00+00:00 Copyright (c) 2024 Padri Achyarsyah, Rizki Nurul Nugraha, Dipa Teruna Awaloedin https://wsj.westscience-press.com/index.php/wsist/article/view/849 Characteristics of Tourists Visiting Setu Babakan 2024-04-30T04:22:11+00:00 Dipa Awaloedin dipa.awaludin@unas.ac.id Padri Achyarsyah padri.achyarsyah@unas.ac.id Rizki Nurul Nugraha rizki.nurul@civitas.unas.ac.id Muhammad Surya Saleh MuhammadSuryaSaleh@unas.ac.id <div><span lang="IN">The research with the title "Characteristics of Tourists Visiting Setu Babakan" was chosen to understand more deeply the characteristics of tourists visiting a tourist destination.

Early detection is crucial but is often hampered by the limitations of conventional methods in analyzing medical images and laboratory results. Machine learning and artificial intelligence technologies, particularly Genetic Evolutionary Algorithm (GA) and Linear Discriminant Analysis (LDA), offer opportunities to improve diagnosis accuracy. This research explores the combination of GA and LDA to improve liver disease detection using the ILPD (Indian Liver Patient Dataset) dataset from the UCI Machine Learning Repository. This study aims to optimize feature selection and classification to improve detection accuracy. The research method includes the use of GA for feature selection and LDA for dimensionality reduction and classification. Tests were conducted on various parameters such as the number of generations, population size, and the combination of crossover and mutation rates in the genetic algorithm. The test results show that the best parameter combination (generation 400, population size 40, crossover rate 0.9, and mutation rate 0.1) results in an Average Forecast Error Rate (AFER) value of 0.0345%, which indicates that the developed detection model is highly accurate. This study shows that the combination of GA and LDA can improve the effectiveness of liver disease detection compared to conventional methods, with potential practical applications in clinical diagnosis systems.</p> 2024-04-30T00:00:00+00:00 Copyright (c) 2024 Dwi Ari Suryaningrum, Muhammad Romadhoni Indra Firmansyah
