Abstract

Divorce is one of the social problems that continues to increase and affects family harmony as well as children’s psychological development. Based on data from the Religious Court of Kuranji District, Padang City, during 2022–2024, divorce cases experienced fluctuations with a significant increase. This issue encourages the need for a system that can help predict divorce rates as a basis for decision-making. This study applies data mining using the C4.5 algorithm to classify the factors causing divorce, such as continuous disputes, physical abandonment, economic issues, and other factors. The C4.5 algorithm was chosen because it can generate decision tree models that are easy to interpret and effective for prediction. This research produced a web-based system that provides predictive information about divorce rates, which is expected to assist the religious court and government in anticipating and reducing divorce cases. The results show that the implementation of the C4.5 algorithm can provide more accurate solutions in predicting divorce rates by utilizing available data and has the potential to be a useful decision support tool.

Abstract

Cats are among the most popular pets in society due to their friendly and active nature. Scientifically known as Felis Silvestris Catus, cats are one of the most commonly kept pets by humans. In addition to being adorable animals, they are also known for their ability to adapt easily. Cats that are not properly cared for, however, are highly susceptible to various diseases. Diseases in cats are often caused by viruses, parasites, or bacteria that inhabit the cat’s body without the owner’s awareness. Several infectious diseases include Feline Panleukopenia (FPV), Feline Infectious Peritonitis (FIP), Feline Calicivirus (FCV), and Scabies. Meanwhile, non-infectious diseases include Hernia, Abscess, Kidney Failure, and Diabetes Mellitus. From these two categories of diseases, solutions to the problems can be determined by using an expert system. This study aims to develop an Android-based expert system application that can assist cat owners in diagnosing diseases quickly and practically. The method used is forward chaining, as it can trace the symptoms entered by users step by step until reaching a conclusion in the form of a disease diagnosis. The results of the testing show that the application is able to provide diagnoses with a fairly good level of accuracy.

Abstract

The rapid development of information technology has brought significant changes in various aspects of life, including tourism and cultural preservation. One of the cultural heritages located in Solok Selatan Regency is the Seribu Rumah Gadang Cultural Heritage Area, which holds high historical and cultural value. However, limited information regarding the location and description of tourist attractions in this area causes many people and tourists to be unaware of its existence. This research aims to develop a Geographic Information System (GIS) based on Android by utilizing ArcGIS as a platform for mapping the location points of the Seribu Rumah Gadang Cultural Heritage. The system not only displays the location of tourist objects but also provides additional information such as historical descriptions, addresses, and other details to help tourists obtain accurate information. With this application, it is expected to improve information accessibility, support cultural preservation, and contribute to tourism development in Solok Selatan Regency.
