Abstract

Difficult integral problems that cannot be solved analytically often require numerical approaches. PHP (Perl Hypertexr Prepocessor) programming has become one of the tools that can be used to solve numerical problems. This research aims to develop a numerical integration program using the Simpson 3/8 method and Romberg method on polynomial, exponential, and trigonometric functions with PHP programming, as well as to compare the efficiency of both methods based on relative error and execution time. Based on the implementation of the algorithms of both methods in PHP programming, the research results show that the average error for the Simpson 3/8 method and Romberg method are 0,013787% and 0,001356%, respectively. The comparison of errors between these two methods indicates that the Romberg method is 9,89% more accurate than the Simpson 3/8 method. However, in terms of program execution time, the Simpson 3/8 method requires less time compared to the Romberg method. The average execution time for the Simpson 3/8 method and Romberg method are 0,00117 seconds and 1,77811 seconds, respectively, and the comparison of execution time between these two methods shows that the Simpson 3/8 method is shorter than the Romberg method when using the same number of iterations.

Abstract

Difficulties in learning can be one of the factors that cause learning obstacles. Learning obstacles can interfere with students' learning process internally and externally. This study aims to analyze learning obstacles that arise at the junior high school level to be the basis for making further designs. The research methodology used is a systematic literature review by collecting articles related to learning obstacles at the junior high school level. The data analysis technique used is data extraction. The data obtained were 15 articles related to learning obstacles in mathematics material at the junior high school level in the 2021-2024 period. The results obtained were ontogenic barriers, epistemological barriers, and didactic barriers. The ontogenic barriers obtained were students' unpreparedness during learning, lack of interest and motivation to learn, and lack of understanding of prerequisite material. The epistemological barriers obtained were misconceptions, unable to understand, identify, and analyze problems, inaccuracy, and limitations in solving the questions given. The didactic barriers obtained were teacher-centered learning, fast learning rhythm, inappropriate teaching material arrangements, and inadequate school facilities. Based on the obstacles obtained, a learning flow can be designed, and a didactic design can be developed to minimize the emergence of these learning obstacles.
