Abstract

Faktor-faktor yang mempengaruhi mutu pelayanan terhadap kepuasan nasabah dapat ditentukan oleh analisis regresi, seperti analisis regresi komponen utama dan analisis regresi stepwise. Model yang diperoleh dari kedua metode tersebut kemudian dibandingkan dengan melihat nilai adjusted R2 karena kemungkinan perbedaan jumlah variabel yang dihasilkan. Analisis regresi komponen utama menghasilkan model Y = -1.013 + 0.1408X1 + 0.1638X2 + 0.1939X3 + 0.1665X4 + 0.1677X5 dengan nilai adjusted R2 sebesar 0,817 sedangkan analisis regresi stepwise menghasilkan model Y = -1,092 + 0,143X1 + 0,181X2 + 0,250X3 + 0,260X5 dengan nilai adjusted R2 0,811. Kesimpulannya adalah besar nilai adjusted R2 dari model regresi yang menggunakan metode regresi komponen utama tidak berbeda jauh dibandingkan dengan menggunakan metode regresi stepwise sehingga model regresi komponen utama dapat digunakan sebagai model alternatif dari regresi stepwise untuk melihat hubungan antara variabel bebas dan variabel terikatnya.

Abstract

This study aims to implement digital comics as a learning medium to enhance mathematical thinking in students with Autism. Students often struggle with understanding abstract concepts and require a visual and structured storytelling approach. Therefore, digital comics offer a combination of narrative, illustrations, and digital interactions that can help them comprehend mathematical concepts more effectively. This study employs an experimental approach with a pretest-posttest design on a group of autistic students at a Special Needs School (SLB) in Malang City. The developed digital comics focus on basic number concepts, including number recognition, simple arithmetic operations, and numerical relationships. Data were collected through mathematical concept comprehension tests, observations of student engagement during learning, and interviews with teachers and parents. The results indicate that the use of digital comics can progressively improve student engagement, mathematical concept comprehension, and mathematical thinking skills. Students demonstrated better recognition of numerical patterns, understanding of number relationships, and the ability to solve simple problems with the aid of engaging visuals. This study provides recommendations for educators to integrate digital comics as an inclusive learning medium that supports students in developing a more meaningful understanding of mathematical concepts.
