Abstract

Paraphilias are a group of disorders related to sexual activity that society considers strange or abnormal. This causes many people with paraphilia to experience ostracism and hide their condition. Even though social media and news report on the increasing phenomenon of paraphilia, there are still many people who don't know how to deal with this condition. Economic limitations and embarrassment discourage many people from visiting specialists such as psychologists, especially since most of them live in big cities. This makes it difficult for the public to access accurate information and early diagnosis. This factor causes people with possible paraphilia to be less aware of their condition and reluctant to seek treatment. This study uses additional methods such as forward chaining and Bayes' theorem to overcome the uncertainty of diagnosis and increase the level of accuracy. This expert system can assist the community in carrying out an accurate self-diagnosis to detect possible paraphilia. This system is capable of diagnosing 8 types of paraphilia with 31 symptoms.

Abstract

The Bisma Kasada (Commanditaire Vennootschap/CV) is a company that provides technical consulting services to communities and governments. The Bisma Kasada covers various aspects of the field of work with minimal qualifications, including the process of promoting consultant services aspecially in the field of architecture. The Bisma Kasada continues to operate conventionally, with architects creating design portfolios of 2-dimensional and 3-dimensional architectural drawings of buildings or spatial layouts. Then, architects promote or market the portfolio to the public through printed brochures and social media. Using this method still presents several challenges, including the time, costs, and energy required for promotional activities, the challenge of updating product data, and the limited scope of promotion and marketing in the surrounding environment. The goal of this research is to develop an Android mobile-based E-Catalogue application, which can serve as a promotional and marketing tool for architectural design of the portfolios. The application, designed by the Bisma Kasada, incorporates a feature for cost estimation and calculation. In building the application, the author used the waterfall method, which consists of analysis stages, design stages, coding stages, and testing stages. We build the application based on android platform using the Kodular framework and Airtable database to strongly interfaced but simplify in the system.

Abstract

The author created an information system for alumni data and the job market at SMKN 1 Kutacane because alumni data has not been completely organized and the data available in the files only presents graduate data and diploma proposal data. There is another problem with the running system, namely that the school has difficulty tracking identity. career alumni who have worked, married, or continued their education, as well as schools have difficulty providing or recommending job vacancy information on the job market, because alumni data is not yet available at the school, and they still use manuals via WhatsApp groups. Therefore, the author created a system information on alumni data and special job markets with recommendations using web-based content based filtering methods. The content based filtering method can be used to suggest job vacancy information that matches the profile of the user or job seeker. user or job seeker profile so that it can simplify the process of searching for information. A special job market application is used to recommend appropriate job vacancy information for student alumni. This system can make it easier for teachers to obtain alumni data and can help with accreditation with alumni data.

Abstract

The diversity of traditional dance performances in Indonesia showcases the country's rich cultural heritage. The art of Rantak dance from West Sumatra, Indonesia, is one such cultural treasure that exhibits connections with ethnomathematics. This research aims to explore the relationship between culture and mathematics education in schools by identifying aspects of the Rantak dance. The research method employed was qualitative descriptive using an ethnographic approach. Data analysis techniques follow Miles and Huberman's approach, involving data reduction, data display, and drawing conclusions. The findings of this research reveal a significant correlation between the cultural art of Rantak dance from West Sumatra and mathematics. This connection is observed in the floor patterns that form geometric shapes such as triangles and circles. Additionally, the formation of straight lines at 180° is evident within the dance. The musical instruments accompanying the dance also feature mathematical elements, such as the cylindrical shape of the "gandang," resembling a solid geometric figure. This research underscores the cultural ties of the Rantak dance with mathematics and highlights its potential as a foundation for culturally-based mathematics education.
