Abstract

Penelitian ini menerapkan Fuzzy Analytic Hierarchy Process (F-AHP) dan Multi Objective Optimization on the Basis of Ratio Analysis (MOORA) untuk menentukan prioritas kebutuhan tenaga kesehatan pada 20 negara di wilayah Eropa dan Asia Tengah. Enam kriteria digunakan, yaitu jumlah dokter, perawat, bidan, dokter gigi, tenaga farmasi, dan luas daratan. Data diperoleh dari World Health Organization (WHO) dan Worldometer. Metode F-AHP digunakan untuk menentukan bobot kriteria melalui matriks perbandingan berpasangan berbasis Triangular Fuzzy Number (TFN), sedangkan MOORA digunakan untuk menghitung nilai preferensi dan peringkat alternatif melalui matriks terbobot. Hasil F-AHP menunjukkan bahwa jumlah dokter memiliki bobot tertinggi, diikuti jumlah perawat, bidan, dokter gigi, tenaga farmasi, dan luas daratan. Hasil MOORA menunjukkan bahwa San Marino, Andorra, dan Montenegro menjadi tiga alternatif dengan prioritas tertinggi. Temuan ini menunjukkan bahwa integrasi F-AHP dan MOORA dapat menghasilkan proses pemeringkatan yang sistematis dan terukur. Namun, interpretasi hasil tetap perlu mempertimbangkan bahwa data yang digunakan bersifat absolut dan belum memperhitungkan rasio tenaga kesehatan terhadap jumlah penduduk.

Abstract

This paper investigates the connections between the Jacobson graph and the algebraic properties of rings through the analysis of the Jacobson graph of the ring \mathbb{Z}_{3p}, where p is a prime number greater than 3. The Jacobson graph of a commutative ring R is constructed by taking the elements of R, excluding its Jacobson Radical, as vertices, and connecting two distinct vertices if 1 minus their product is not a unit in R. The F-Index is utilized to capture and represent the structural properties of the ring through its associated graph. A detailed examination of the Jacobson Radical, maximal ideals, and vertex degrees in \mathbb{Z}_{3p} leads to the calculation of the F-Index, providing insights into the graph’s connectivity and underlying algebraic structure. This study contributes to the intersection of algebra and graph theory, offering a foundation for further research into more complex algebraic structures.

Abstract

The development of the 21st century demands that students not only have the ability to think critically and creatively, but also communication skills, especially in mathematics learning. However, various studies show that students still have difficulty communicating their mathematical ideas, both verbally and in writing, especially when working in groups and facing contextual problems. The purpose of this study is to describe the mathematical communication profile of students in solving contextual problems collaboratively reviewed based on high, medium, and low self-efficacy. A qualitative approach with an exploratory research type is used in this study. The subject of the study is a student of class XI MAN 2 Malang. The research data were obtained through the results of the Contextual Problem Solving Task (TPMK) and interviews. Data analysis was carried out by the triangulation method. The results showed that students with high self-efficacy tended to communicate their mathematical ideas orally. Students with self-efficacy showed balanced verbal and written communication but were less consistent in explaining mathematical models and operations, while students with low self-efficacy were more dominant in written communication.
