The decorative arts that adorn this mosque are generally found in elements such as doors, windows, walls, gates, and vents, which show special patterns. Such patterns can be identified through the concept of geometric symmetry, specifically Frieze Patterns and Wallpaper Patterns. The Frieze pattern is a subgroup within a symmetry group formed through one-way translation, creating a linear pattern that repeats in one direction. There are seven types of frieze patterns, each formed through a combination of specific isometries. Along with that, there are also other geometric patterns known as wallpaper patterns. Wallpaper patterns analyze patterns based on transformations on a flat plane and have seventeen types. This study aims to explore and explain geometric patterns based on Frieze Patterns and Wallpaper Patterns contained in the decorative arts of Istiqlal Mosque. Data collection methods involve observation and documentation. The results showed that there are certain frieze patterns in the Istiqlal Mosque, such as the type . Meanwhile, the wallpaper patterns identified in the design of the Istiqlal Mosque are type pmm and pmg. It is important to note that not all designs in the decorative arts of Istiqlal Mosque can be categorized into seven frieze patterns as well as seventeen wallpaper patterns.","PeriodicalId":299241,"journal":{"name":"JMT : Jurnal Matematika dan Terapan","volume":"84 14","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140423604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Holidays to tourist attractions can eliminate boredom, improve the brain's work system, and foster a feeling of happiness. Holidays to tourist attractions can be assisted by travel agents. This research was carried out by looking for the shortest route from tour packages the travel agent in Banyuwangi. Search for the shortest route is aim to save time on travel package rundown tour, the distance traveled, and the fuel used. Search for the shortest route can be calculated using Floyd Warshall Algorithm. This algorithm was chosen because it can evaluate each pair vertex at each iteration to find the shortest distance. Search for the shortest distance is checking each pair vertex and choosing the smallest distance between the actual distance and the initial distance plus the final distance. The results of this research are found in the last iteration of each tour package. The total distance of the tour package is calculated using the Floyd Warshall Algorithm to get smaller distance than the total distance of the tour package with the route taken normally. Tour package distance using Floyd Warshall Algorithm experienced distance savings seen from the difference between the two.","PeriodicalId":299241,"journal":{"name":"JMT : Jurnal Matematika dan Terapan","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126453512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the events that need to be predicted is the impact of the earthquake. The Meteorology, Climatology and Geophysics Agency (BMKG) classifies earthquake impacts based on the BMKG Earthquake Intensity Scale (SIG-BMKG) which consists of 5 scales. In making predictions on a problem, you can use data mining that extracts data into useful information. Grouping the impact of an earthquake is one of the tasks of data mining, namely classification. Prediction can be viewed as a classification that groups data into predefined classes. One classification method is the Decision Tree. This method can handle both categorical and numerical data on large data. Some of the algorithm of the Decision Tree method are ID3, CART, and C4.5. The C4.5 algorithm is an improved ID3 algorithm so that it can handle missing values and continuous data. This study aims to construct a model and analyze the performance of the model obtained using the Decision Tree method with the C4.5 algorithm. In determining the best model, you can utilize Split Validation and k-fold Cross Validation. The best model was obtained in the first iteration of 10-fold Cross Validation. The best model is then used in a web application that can be used by the community to predict the impact of earthquakes that occur in Indonesia.","PeriodicalId":299241,"journal":{"name":"JMT : Jurnal Matematika dan Terapan","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122651492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
