Abstract

Perhitungan integral merupakan salah satu konsep penting dalam matematika yang sering digunakan untuk menentukan luas area di bawah kurva. Namun, tidak semua fungsi dapat diintegralkan secara analitik karena kompleksitas bentuknya. Oleh karena itu, metode numerik seperti metode Simpson 3/8 dan metode Boole diperlukan sebagai pendekatan untuk memperoleh nilai hampiran dari integral tentu. Kedua metode ini memiliki kelebihan masing-masing dalam hal akurasi dan efisiensi. Penelitian ini bertujuan untuk menganalisis efektivitas metode integral numerik Simpson 3/8 dan metode Boole dalam menentukan luas area di bawah kurva melalui implementasi dalam bahasa pemrograman PHP. Penelitian ini menggunakan pendekatan eksperimen murni dengan mengimplementasikan algoritma kedua metode ke dalam aplikasi berbasis web. Pengujian dilakukan pada berbagai jenis fungsi polinomial, transenden, dan trigonometri—dengan membandingkan hasil pendekatan terhadap nilai eksak. Analisis dilakukan berdasarkan dua aspek utama, yaitu efektivitas (dilihat dari akurasi) dan efisiensi (dilihat dari waktu komputasi). Hasil penelitian menunjukkan bahwa metode Boole memiliki tingkat akurasi yang lebih tinggi dibandingkan metode Simpson 3/8. Rata-rata galat yang dihasilkan oleh metode Boole untuk fungsi polinomial, transenden, dan trigonometri masing-masing adalah , , dan . Sebaliknya, metode Simpson 3/8 mencatat galat rata-rata sebesar , , dan 8 pada fungsi-fungsi yang sama. Di sisi lain, metode Simpson 3/8 lebih efisien dalam hal waktu eksekusi, dengan rentang waktu antara 0,49200 ms hingga 0,605625 ms, dibandingkan metode Boole yang membutuhkan waktu antara 0,475125 ms hingga 0,776625 ms. Selisih waktu ini, meskipun kecil, menunjukkan bahwa Simpson 3/8 lebih cocok digunakan pada sistem yang memerlukan kecepatan respons tinggi.

Abstract

This research was conducted to describe the mathematical representation abilities of eighth-grade students at SMPN 13 Mataram on the topic of Two-Variabel Linear Equation Systems (SPLDV), viewed from the introvert and extrovert personality types. A qualitative research method was used with descriptive approach. The subjects were chosen using purposive sampling and involved 4 students selected based on personality questionnaires and mathematical representation ability tests, followed by interview. Data was collected through non-tes instruments Eysenck Personality Inventory (EPI), essay questions on mathematical representation ability test and interviews which is then analyzed descriptively to find out the differences in verbal, symbolic and visual representation abilities between introvert and extrovert students. The data analysis uses the interactive analysis model from Miles & Huberman. The results showed that introvert students have very good verbal and symbolic representation skills, but still weak in visual representation because none of them could answer correctly. Extrovert students also have good verbal and symbolic representation skills, more confident in answering, but less detailed and tend to rush. Just like introvert, extrovert students also couldn’t represent SPLDV visually in the right way. The main difficulty for both personality types is in converting the information in the problem into a visual representation caused by a lack of experience and practice in drawing graphs.

Abstract

Mathematical problems frequently arise in various scientific fields, particularly in determining the roots of nonlinear functions. Since complex nonlinear functions are often difficult to solve analytically, numerical methods are commonly used as an alternative approach. This article aims to compare the number of iterations and the error levels produced by the Newton-Raphson and Steffensen methods. The tests were conducted on three types of functions, polynomial functions of the form a1xn+a2xn-1+...+amx0, exponential functions of the form aebx+d+t and trigonometric functions of the form a0sin(b0x)+a1cos(b1x)+a2. For each type, three different functions were used, and each was tested with three different initial guesses. The results show that, in terms of iteration count, the Newton-Raphson method outperformed the Steffensen method for polynomial and trigonometric functions by 84% and 62%, respectively, while for exponential functions, the Steffensen method was superior by 12%. In terms of error, the Newton-Raphson method yielded smaller errors across all function types, with improvements of 92%, 84%, and 98% for polynomial, exponential, and trigonometric functions, respectively, compared to the Steffensen method.
