Abstract

Cancer is a dangerous disease that arises from the conversion of normal cells into tumor cells that develop into malignant tumors. According to WHO, cancer is the second deadliest disease in the world. About 70% of cancer deaths occur in low and middle income countries such as Indonesia. Cancer can be detected by recognizing patterns of expression of human genes. DNA Microarray is a technology that can find patterns of gene expression in a variety of different conditions by means of microarray data classification. Microarray data has very large dimensions and needs to be reduced in order to obtain informative genes to detect cancer optimally. In this study, the authors use the Least Absolute Shrinkage and Selection Operator (LASSO) as a feature selection method to reduce data dimensions and Functional Link Neural Network (FLNN) as a classification method with Legendre Polynomial base functions. With a series of processes that have been carried out, obtained an average accuracy of 86.41% and an average f1-score of 81.83%

Abstract

Children with intellectual disabilities often experience significant barriers to verbal communication, including difficulties speaking, understanding messages, and participating in conversations. These problems impact their ability to establish social interactions and express their needs. This research aims to describe how the role-playing method is implemented to train verbal communication skills in children with intellectual disabilities. This study employed a qualitative, descriptive approach. Data were collected through observation, in-depth interviews, and documentation. The research subjects consisted of one teacher and four students with mild intellectual disabilities at the junior high school level, selected through purposive sampling. Data validity was established through triangulation techniques. Data analysis was conducted through data reduction, data presentation, and conclusion drawing. The results demonstrate that the role-playing method was implemented through eight systematic stages: scenario development, instruction, role selection, demonstration, activity implementation, guidance and reinforcement, post-activity discussion, and evaluation. This learning process helped children become more courageous in speaking, imitate simple expressions, and respond to conversation partners more effectively. These findings demonstrate that role-playing can be an appropriate learning approach for children with intellectual disabilities in the context of verbal communication training. Furthermore, this method proved effective in building confidence and encouraging active participation in learning activities.
