Abstract

This research discusses a numerical method for determining the stationary waves as a solution of Nonlinear Schrödinger (NLS) equations. In general, solutions for the partial differential equations can be solved analytically. However, most the solutions of the nonlinear wave equations are difficult to determine analytically. Therefore, a numerical approach is needed to determine the solution of the NLS equation. One of the numerical methods can be used to find the solution of the NLS equation is the Petviashvili iteration method. For case study, the NLS equation has been generated by the theory of Bose-Einstein condensation which contain potential function . To solve this problem, we generalized Petviashvili iteration method to determine the stationary waves solution easily. The most interesting result for this study is by modification of Petviashvili iteration method, we can make it easier to find a stationary solution for the nonlinear Schrodinger equation which containing the Bose-Einstein condensation potential function .

Abstract

Kemampuan literasi siswa Indonesia, khususnya bidang matematika masih tergolong rendah. Hal ini tercermin dari peringkat skor PISA (Program for International Student Assesment) dunia yang dirilis oleh OECD (Organization for Economic Cooperation and Development) yang menempatkan siswa Indonesia di posisi ke 71 dari 79 negara. Artikel ini memaparkan sebuah hasil analisis Kemampuan Literasi Bidang Matematika Siswa Madrasah Aliyah Manhalul Ma’arif Darek Lombok Tengah, NTB. Proses analisis diawali dari pemberian soal (pretest) jenis PISA bidang Matematika tanpa perlakuan kepada 35 siswa kelas 10. Selanjutnya dengan metode diskusi dan kerja kelompok untuk meningkatkan Strategi Metakoginisi Membaca persoalan matematika, soal serupa kembali diberikan pada siswa yang sama. Hasil asesmen menunjukkan ada peningkatan signifikan dari 6% siswa menjawab benar pada pretest, menjadi 77% siswa menjawab benar pada postest.

Abstract

The community engagement activity carried out by the teaching team from the Mathematics Program of the Faculty of Mathematics and Natural Sciences at Universitas Mataram to SMAN 1 Selong has successfully introduced students to the importance of statistics and game theory in decision-making. Through stories and real-life cases, students are encouraged to consider factors such as averages and standard deviations in making informed decisions. They also learn about the story of John Nash, who discovered game theory, and compare it to the economic principles of Adam Smith. Students realize that collective interests can lead to better outcomes than personal interests. In the case of The Prisoner's Dilemma, students also see the importance of game theory in the context of collective decision-making. Overall, this activity helps students understand the importance of statistics and game theory in the decision-making process.
