Students' understanding on the concept of a circle especially the relationship between central angle, arc length, and sector area of the circle based on learning obstacle and learning trajectory need to be developed well by creating a good didactic design. Therefore, it is necessary to design hypothetical learning trajectories (HLT) for students in learning sector area and arc length using the clockwork context. The didactical design was developed through three stages, namely: (1) the preliminary design; (2) teaching experiment; and (3) retrospective analysis. This study focused on the first stage, since the main purpose of this research was to develop a series of learning activities to delve into the concept of sector area and arc length as proportional problem in the form of HLT. The HLT was designed using a realistic mathematics education (RME) approach. There are three anticipated learning obstacles in the design of the activities, including errors related to the concept of the relationship between arc length, circle circumference, sector area, and circle area; errors related to the concept of the relationship between the central angle, arc length, and sector area of a circle; as well as errors related to the connection of concepts in circle material with other mathematical material; and students' difficulties in problem solving questions.

Given a graph G=(V(G),E(G)). Let S={s1,...,sk} be an ordered subset of V(G). Consider a vertex x, a coordinate of x with respect to S is represented as r(x|S)=(d(x,s1),...,d(x,sk)) where d(x,si) equals the number of edges in the shortest path between x and si for i=1,...,k. The minimum value of k such that for every x has distinct coordinate is called metric dimension of G. Turán graph T(n,r), n>=r>=2 is a subgraph of complete r-partite graph on n vertices having property that the difference of cardinality of any two distinct classes is at most one. In this paper, we build a new graph namely a banded-Turán graph, BT(n,r,m), as a graph built by a Turán graph T(n,r) and r uniform path graphs Pm in which every vertex of each class of T(n,r) connected to an initial vertex of corresponding path graph Pm. Intuitively, this graph illustrates as if a Turán graph is banded by r uniform ropes. We determine some basic graph properties including independence number, chromatic number, and diameter of banded-Turán. The main result in this paper is we obtain that the metric dimension of banded-Turán turns out that it depends on the number of its classes. If it has two classes then the metric dimension is equal to n-1 and if it has more than two classes then the metric dimension is equal to the metric dimension of Turán graph included in it.

Spektrum dari suatu graf adalah susunan nilai eigen dari matriks ketetanggaan graf beserta multiplisitasnya. Spektrum graf yang dihasilkan dari matriks Laplace disebut spektrum Laplace. Matriks Laplace dari graf diperoleh dari selisih matriks ketetangaan graf dengan matriks diagonal dimana elemen-elemen diagonal utamanya merupakan derajat simpul dari graf. Penelitian ini mengkaji bentuk spektrum Laplace dari graf Mahkota dan graf Benteng. Graf Mahkota adalah graf yang diperoleh dari komplemen hasil perkalian kartesian graf Lengkap K2 dan graf Lengkap Kn. Sementara itu graf Benteng Bnn adalah graf yang diperoleh dari hasil perkalian kartesian dua buah graf Lengkap Kn. Hasil penelitian telah diperoleh polinomial karakteristik dari matriks Laplace untuk graf Mahkota dengan n>=3 dan graf Benteng Bnn dengan n>=2. Lebih lanjut spektrum Laplace dari kedua graf juga telah diperoleh. The spectrum on a graph is a set of eigenvalues of the adjacency matrix along with their multiplicities. The spectrum of a Laplace matrix is called the Laplace spectrum. The Laplace matrix of a graph is obtained from the difference between a adjacency matrix and a diagonal matrix where the elemens of main diagonal are the vertices degree of the graph. This research studied the Laplace spectrum on the crown graph and the rook graph. A crown graph is a graph obtained from the complement of the cartesian product of complete graph K2 and Kn. Meanwhile, rook graph is a graph obtained from the cartesian product of two complete graph Kn. The results of study are formula of the characteristic polynomial of Laplace matrix for the crown graph with n>=3 and the rook graph with n>=2. Furthermore, the Laplace spectrum of both graphs has also been obtained.

Penelitian ini menggunakan metode eksperimen jenis kuasi eksperimen dengan desain Nonequivalent pretest and posttest Control Group Desain. Populasi dan sampel dalam penelitian ini yaitu siswa kelas II Sekolah Dasar berumur antara 8 – 9 tahun yang belum mempelajari materi perkalian, tetapi sudah mempelajari materi pertambahan sebanyak 40 orang Siswa yang ditentukan melalui teknik Purposive Sampling. Hasil penelitian yang diperoleh menunjukkan bahwa kedua metode ini memiliki pengaruh yang sama dalam meningkatkan keterampilan berhitung perkalian dasar Siswa dilihat dari selisih hasil pretes dan posttest yang diperoleh yaitu sebesar 24,05 dan 25,6 . Kemudian, hasil perolehan gainscore yang diperoleh keduanya berada pada tingkat interpretasi sedang yaitu 0,55 dan 0,59. Dapat disimpulkan bahwa metode jarimatika dan metode permainan kartu tidak memberikan pengaruh yang berbeda dalam meningkatkan keterampilan berhitung perkalian dasar pada siswa sekolah dasar dan pengaruh keduanya sama-sama berada pada tingkat interpretasi sedang, sehingga kedua metode ini dapat menjadi alternatif solusi bagi pendidik untuk dapat diterapkan dalam proses pembelajaran materi perkalian dasar yang akan dilaksanakan guna meningkatkan keterampilan berhitung perkalian dasar siswa. This research is motivated by the lack of variety in the use of learning methods used by educators, which has an impact on the low basic multiplication calculation skills of students. Therefore, this research was conducted with the aim of finding out whether or not there is a difference in the influence of using the Jarimatika method and the card game method on elementary school students' basic multiplication counting skills. This research uses a quasi-experimental type of experimental method with a Nonequivalent pretest and posttest Control Group Design. The population and sample in this study were class II elementary school students aged between 8 - 9 years who had not studied multiplication material, but had studied addition material as many as 40 students who were determined using the Purposive Sampling technique. The research results obtained show that these two methods have the same effect in improving students' basic multiplication numeracy skills as seen from the difference in pretest and posttest results obtained, namely 24.05 and 25.6. Then, the gainscore results obtained by both were at a medium interpretation level, namely 0.55 and 0.59. It can be concluded that the Jarimatika method and the card game method do not have a different influence in improving basic multiplication counting skills in elementary school students and the influence of both is at a moderate level of interpretation, so that these two methods can be an alternative solution for educators to be applied in the process of learning basic multiplication material that will be carried out in order to improve students' basic multiplication calculation skills.

Salah satu faktor yang menyebabkan hal tersebut adalah metode pembelajaran yang digunakan oleh guru adalah metode ceramah tanpa menggunakan media pembelajaran. Tujuan penelitian ini adalah untuk mengetahui pengaruh penggunaan media tangram berbasis Articulate Storyline 3 terhadap kemampuan berpikir kreatif siswa dalam materi bangun datar kelas IV SDN Karangantu sebanyak 38 siswa tiap kelas. Pendekatan penelitian yang digunakan adalah kuantitatif dengan jenis penelitian quasi experiment design bentuk nonequivalent control group design. Teknik pengumpulan data adalah menggunakan tes uraian materi bangun datar yang mengandung indikator kemampuan berpikir kreatif. Hasil penelitian menunjukkan bahwa penggunaan media tangram berbasis Articulate Storyline 3 memiliki pengaruh terhadap kemampuan berpikir kreatif siswa dalam materi bangun datar kelas IV di SDN Karangantu. Hal ini dapat dilihat dari hasil uji hipotesis menggunakan Independent Sample t-test menghasilkan thitung > ttabel (4,8 > 2,0) yang menunjukkan bahwa penggunaan media tangram berbasis Articulate Storyline 3 lebih baik digunakan dari pada pembelajaran secara konvensional terhadap kemampuan berpikir kreatif siswa dalam materi bangun datar. Dengan penggunaan media tangram berbasis Articulate Storyline 3 pengaruh yang diberikan terhadap kemampuan berpikir kreatif siswa dalam materi bangun datar lebih tinggi. The creative thinking skills of students in Indonesia are still underdeveloped and relatively low. The same thing was found at SDN Karangantu. There are still many students who cannot explain in detail the questions given. One of the factors that causes this is the learning method used by the teacher is the lecture method without using learning media. The purpose of this study was to determine the effect of the use of tangram media based Articulate Storyline 3 on students' creative thinking abilities in class IV SDN Karangantu consisting of 38 students per class. The research approach used was quantitative with a quasi-experimental design type of nonequivalent control group design. The data collection technique is to use a flat material description test that contains indicators of the ability to think creatively. The results showed that the use of tangram media based Articulate Storyline 3 had an influence on students' creative thinking abilities in class IV flat shape material at SDN Karangantu. This can be seen from the results of the hypothesis using Independet Sample t-test testing yielding tcount > ttable (4.8 > 2.0) which indicates that the use of tangram media based Articulate Storyline 3- is better used than conventional learning on students' creative thinking abilities in flat shape material. With the use of tangram media based Articulate Storyline 3 the influence is given to students' creative thinking abilities in higher flat shape material.
