Abstract

Anak Berkebutuhan Khusus adalah anak yang dalam pendidikan memerlukan pelayanan yang spesifik, berbeda dengan anak pada umumnya. Ketunaan anak berkebutuhan khusus dibagi menjadi beberapa golongan antara lain: tunanetra, tunarungu, tunagrahita, tunadaksa, dan autis. Anak tunarungu akan memiliki hambatan dalam komunikasi verbal/lisan, baik itu secara ekspresif maupun reseptif. Dalam hal tersebut anak berkebutuhan khusus terlebih tunarungu dalam pendidikannya juga mengalami kesulitan belajar. Kesulitan belajar yang terkait dengan perhitungan matematika dinamakan diskalkulia. Mengenal bilangan merupakan salah satu kesulitan belajar matematika yang dialami oleh siswa tunarungu. Untuk mengetahui diskalkulia pada anak berkebutuhan khusus tunarungu dalam mengenal bilangan maka peneliti mengambil penelitian tersebut. Jenis penelitian ini adalah penelitian deskripsi dengan pendekatan kualitatif. Adapun subjek penelitian ini yaitu siswa kelas 3 golongan tunarungu di SLB Negeri Branjangan Jember tahun ajaran 2022/2023 sebanyak 2 siswa. Hasil penelitian akan mengidentifikasi disklakulia pada anak berkebutuhan khusus tunarungu dalam mengenal bilangan secara individu yang didapatkan dari data observasi, tes, dan wawancara. Hasil penelitian ini yaitu pada S1 diskalkulia yang sesuai dengan karakteristik diskalkulia yaitu gangguan persepsi visual. Sedangkan S2 memiliki diskalkulia pada jenis diskalkulia yaitu diskalkulia verbal dan karakteristik diskalkulia yaitu gangguan perhatian.

Abstract

Children with Special Needs are children who in education require specific services, different from children in general. Children with special needs are divided into 10 groups, namely: Blind, mentally retarded, dyslexic, hyperactive, mentally impaired, deaf, mute, autistic, disabled, gifted child. Blind is someone who has less accurate/poor vision compared to sighted people, even though they already assisted with visual aids, and cause them to require a lot of energy and time to do visual tasks. Therefore, blind children experience more difficulties in their education. Learning difficulties in mathematics are called dyscalculia. The most basic dyscalculia experienced by blind children is knowing numbers. So to find out the dyscalculia experienced by children with special needs who are blind in knowing numbers, the researchers took this research with a descriptive type of research and with a qualitative approach. The subjects of this study consisted of 2 students from class 4 of the blind group at SDLB Negeri Branjangan for the 2022/2023 academic year. The results of identification of dyscalculia in children with special needs in recognizing numbers are presented in the form of a description of each individual obtained from observation data, tests and interviews. The results of this study were that S1 subjects had dyscalculia on the characteristics of dyscalculia, namely visual motor associations and attention disorders, on the classification of dyscalculia, namely knowledge of numbers, on the types of dyscalculia, namely weak in planning and inability to do simple calculations. Whereas subject S2 has dyscalculia in the types of dyscalculia, namely weak in planning and inability to do simple calculations. Keywords: Children with Special Needs, Blind, Dyscalculia

Abstract

The main focus of this research is to identify geometric patterns that may be hidden within the dimensions, shapes, and orientations of the dolmens. Overall, the objective is to identify, analyze, and understand the ethnomathematical concepts embedded in the dolmens at the Duplang Site. The specific aims include documenting the dimensions, comparing them with other sites, and interpreting their cultural significance. This study employs a qualitative descriptive method with an ethnographic approach. The research methods involve direct observation, documentation, interviews, visual analysis, and precise measurements using a measuring tape. The outcomes of this exploration are expected to make a significant contribution to our understanding of the cognitive abilities of prehistoric communities. The main outputs include a comprehensive research report and the identification of unique mathematical patterns such as hidden geometries

Abstract

Let G be a connected and simple graph with vertex set V(G) and edge set E(G). For a graph G, we define k-labeling such that the edges of G are labeled with integers {1,2,3,....,k_e} and the vertices of G are labeled with even integers {0,2,4,....,2k_v}, where k=max{k_e, 2k_v}. If there is a different weight for all edges, then the labeling is called edge irregular reflexive k-labeling. The weight of edge xy, notated by wt(xy) is defined as a sum of label of x, label of xy, and label of y. The minimum k for which G has an edge irregular reflexive k-labeling is defined as reflexive edge strength of G, symbolized by res(G). In this research, we determined the reflexive edge strength of several Cartesian graphs, namely P_5xP_n, S_4xP_n, C_5xC_n, and F_3xP_n. Keywords: Edge irregular reflexive k-labeling, reflexive edge strength, Cartesian graph.
