Abstract

Abstrak: Tujuan yang ingin dicapai dalam penelitian ini adalah untuk mengetahui persepsi mahasiswa terhadap penggunaan ChatGPT di era Pendidikan dengan membandingkan persepsi antara perempuan dan laki-laki berdasarkan gender. Penelitian ini menggunakan metode kuantitatif dengan pendekatan survey. Instrumen yang di gunakan berupa angket sebanyak 10 soal/pernyataan dengan skala likert 5 options. Analisis data yang digunakan yaitu statistik deskriftif dan uji-t independent menggunakan SPSS. Hasil analisis data menunjukan persepsi mahasiswa terhadap penggunaan ChatGPT dengan nilai rata rata sebesar 75,69%. Selanjutnya pada uji-t yang telah dilakukan menggunakan SPSS di peroleh nilai uji-t yaitu sebesar -1,991 dengan nilai sig 0,052. Hal ini menunjukan bahwa tidak ada perbedaan yang signifikan (nyata) antara rata-rata hasil persepsi mahasiswa pada kelompok A (perempuan) dengan kelompok B (lakii laki). Abstract: The objective of this research is to explore students' perceptions regarding the use of ChatGPT in the educational landscape by comparing the perceptions between females and males based on gender. This study employs a quantitative method with a survey approach. The instrument used consists of a questionnaire comprising 10 items/statements using a 5-point Likert scale. Data analysis involves descriptive statistics and independent t-test using SPSS. The data analysis results reveal that students' perceptions towards the use of ChatGPT have an average score of 75.69%. Furthermore, the conducted t-test using SPSS yielded a t-value of -1.991 with a significance value of 0.052. This indicates that there is no significant difference between the average perceptions of female (Group A) and male (Group B) students.

Abstract

Multivariable nonlinear equation systems are commonly found in various disciplines such as engineering, physics, economics, and artificial intelligence. Analytical solutions are often difficult to obtain, necessitating the use of numerical approaches. This study aims to evaluate and compare the performance of the Levenberg-Marquardt and Trust-Region methods in solving multivariable nonlinear equation systems. Computational simulations were performed using MATLAB software with an error tolerance of 0.001 and a maximum iteration limit of 100. The test system involved a combination of trigonometric, exponential, and polynomial functions to ensure computational complexity. The study's results show that both methods are capable of achieving solutions with high accuracy. The Levenberg-Marquardt method demonstrated higher efficiency, achieving convergence in only 2 iterations with a final error of 1.866 10. In contrast, the Trust-Region method required 27 iterations but yielded a smaller error of 4.768 10. Three-dimensional visualization revealed that the solution was obtained from the intersection point of the three function surfaces. These findings confirm that the selection of numerical methods should consider the priority between iteration efficiency and solution accuracy. The contribution of this research lies in presenting a comparison of the performance of two popular algorithms with controlled simulation parameters, which can serve as a basis for the development of numerical methods in larger dimensional systems
