Propositional calculus is commonly studied by various students, from high school to college. Propositional calculus studies the truth value (True/False) of a proposition. The proposition is then processed into the steps of working on the proposition according to the order of operator priority, which is packaged into truth tables and logical expressions. The proposition work done is not easy, but consumes a lot of time and writing media if done manually. Errors in doing proposition work result in inaccurate truth values obtained. Therefore, the author is interested in making an application to calculate student grades using the propositional calculus method that can be used to overcome the problem of working on propositions manually, so that it can produce accurate truth values, which can also be used as a learning medium and media for students to calculate and see the results of their grades manually.","PeriodicalId":181319,"journal":{"name":"Hanif Journal of Information Systems","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128687504","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}

FCM is a clustering algorithm where one object can be a member of several clusters and FCM cluster boundaries are vague. The output of FCM is a row of cluster centers and several degrees of membership for each data point. In this clustering, customers will be divided into 4 customer clusters namely Golden, Silver, Bronze, and Iron with the variables used as a reference are the final purchase date, purchase frequency and total purchase. The data used is customer transaction data for the period September - December 2015. The total data is 709 transactions from 75 customers. After the data is processed with the Fuzzy C-Means method, the final results show that the iteration ends at the 30th iteration with a change in the objective function of 9.8. The resulting customer clusters are Golden: 27, Silver: 15, and Bronze: 33 with a cluster validity of 0.596277.\u0000\u0000\u0000\u0000","PeriodicalId":181319,"journal":{"name":"Hanif Journal of Information Systems","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125552149","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}

For this reason, based on the existing problems, this research will design a tourism website using the shopify framework. The purpose of this research is to help make it easier for travelers to find where to visit tourist attractions and to be able to make bookings online so they don't worry about running out of places such as hotel rooms when they arrive at tourist sites. In this study, the Research and Development (R&D) method was used in designing and building a tourism website using the shopify framework. This research succeeded in creating a tourism website using the shopify framework which can be accessed by 2 different parties with a special page, namely the customer on the facilities menu page to place product orders and the admin on the admin page to view and confirm every incoming order, add sales products, change product prices or product images, change or add product descriptions and add new features.\u0000\u0000\u0000\u0000","PeriodicalId":181319,"journal":{"name":"Hanif Journal of Information Systems","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127419396","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}

The purpose of this research is to use the waterfall method to create an e-commerce website that can be opened online with an internet network. The method used by researchers in this study is the waterfall method. This method is used by researchers to develop software systems through a sequential software life cycle, starting with analysis, design, coding, and testing. System themes use PHP, HTML, CSS and Notepad while the database uses My-Sql which is accessed via XAMPP localhost. This research produces a web-based e-commerce application that provides real-time stock information, sales reports, stock reports and stores can advertise the products being sold.
