Abstract

The emergence of various problems during online learning must receive attention, especially for special needs students. For deaf children, online learning problems in mathematics lessons will become more complex due to communication barriers (hearing loss). This study aims to analyze deaf children's mathematical anxiety in learning mathematics and its correlation to the deaf children’s learning outcomes during the Covid-19 pandemic. This research was descriptive and correlational research types. The subject research was deaf children at the SMP Luar Biasa Negeri Tuna Rungu. The study sample was 24 students. Research data was collected by observation, interviews, questionnaires, and tests. The data analysis used was descriptive analysis and simple regression. The results showed that deaf children's mathematical anxiety was very high. The results of the regression analysis show that mathematical anxiety has a significant effect on mathematics learning outcomes. Even though online learning during the pandemic has made the implementation of mathematics learning flexible because it can accommodate different learning styles of children, many obstacles were found in the learning process, given the limitations of deaf children, and they preferred offline learning. The implications of this research are expected to be an evaluation for teachers and deaf children to improve mathematics learning outcomes and to overcome deaf children's mathematical anxiety.

Abstract

Let G(V, E) be a graph with order n with no component of order 2. An edge k-labeling α: E(G) →{1,2,…,k} is called a modular irregular k-labeling of graph G if the corresponding modular weight function wt_ α:V(G) → Z_n defined by wt_ α(x) =Ʃ_(xyϵE(G)) α(xy) is bijective. The value wt_α(x) is called the modular weight of vertex x. Minimum k such that G has a modular irregular k-labeling is called the modular irregularity strength of graph G. In this paper, we define a modular irregular labeling on C_n⊙mK_1. Furthermore, we determine the modular irregularity strength of C_n⊙mK_1.Keywords: corona product; cycle; empty graph; modular irregular labeling; modular irregularity strength. AbstrakDiberikan graf G(V, E) dengan orde n dengan tidak ada komponen yang berorde 2. Sebuah pelabelan-k sisi α: E(G) →{1,2,…,k} disebut pelabelan-k tak teratur modular pada graf G jika fungsi bobot modularnya wt_ α:V(G) → Z_n dengan wt_ α(x) =Ʃ_(xyϵE(G)) α(xy) merupakan fungsi bijektif. Nilai wt_α(x) disebut bobot modular dari simpul x. Minimum dari k sehingga G mempunyai pelabelan-k tak teratur modular disebut dengan kekuatan ketakteraturan modular dari graf G. Pada tulisan ini, didefinisikan pelabelan tak teratur modular pada C_n⊙mK_1. Lebih lanjut, ditentukan kekuatan ketakteraturan modular dari C_n⊙mK_1.Kata Kunci: hasil kali korona; lingkaran, graf kosong; pelabelan tak teratur modular; kekuatan ketakteraturan modular.

Abstract

Sebuah graf G dengan himpunan titik V(G) dan himpunan sisi E(G) dikatakan memiliki pelabelan anggun super jika terdapat fungsi bijektiff : V(G) U E(G) - {1, 2, 3, ..., |V(G)| + |E(G)|}sedemikian hingga untuk setiap sisi uv dalam E(G) berlaku:f(uv) = |(f(u) - f(v)|.Penelitian ini bertujuan untuk membuktikan bahwa graf tripartit komplet K(1,m,n) untuk m,n = 1 memiliki pelabelan anggun super. Metode yang digunakan adalah konstruksi langsung, yaitu dengan memberikan fungsi pelabelan yang memenuhi sifat-sifat pelabelan anggun super pada setiap titik dan sisi graf K(1,m,n).Hasil penelitian menunjukkan bahwa untuk setiap nilai m,n = 1, graf K(1,m,n) dapat dilabeli secara anggun super melalui penentuan label yang sistematis dan terstruktur.

Abstract

Indeks Randic merupakan salah satu indeks topologi dalam teori graf. Untuk suatu graf sederhana tak berarah G. Indeks Randić didefinisikan dengan rumus  , dengan E(G) menyatakan himpunan sisi graf G, serta deg(u) merupakan derajat simpul di simpul u dan deg(v) merupakan derajat simpul di simpul v. Tujuan penelitian ini adalah untuk menentukan nilai indeks Randić dan rumus umum pada gelanggang bilangan bulat modulo n untuk beberapa kasus n yaitu, n merupakan bilangan prima, n merupakan bilangan prima berpangkat, n merupakan perkalian dua bilangan prima dan n merupakan perkalian dua bilangan prima berpangkat. Hasil penelitian menunjukkan bahwa semakin besar bilangan prima pada suatu gelanggang bilangan bulat modulo n maka semakin besar nilai indeks Randić.
