Fuzzy graph is a graph consisting of pairs of vertices and edges that have a membership degree that contains a closed interval of real numbers on each edge and vertex. A fuzzy graph is said to be a strong fuzzy graph if the membership degree of edge with the minimum membership degree of vertex and the same membership degree of vertex for each edge with . This paper explains the properties of fuzzy graph isomorphism including weak isomorphism, co-weak isomorphism, and isomorphism in strong fuzzy graphs.

Based on observation results, students' low level of creative thinking in mathematics lessons is influenced by the use of inappropriate methods, so teachers are required to innovate using fun learning methods. One method that makes students interested in learning mathematics is a realistic mathematics learning method. This research aims to improve students' creative thinking abilities in positive whole number material using a Realistic Mathematics Learning approach. Based on the research results, it was found that students' creative thinking increased from 25.94% to 66.7% in the first cycle, and 80.96% in the second cycle. After conducting research on the Realistic Mathematics Education (RME) approach to improve students' creative thinking, it can be seen from the results of initial observations that there has been quite a significant increase until the second cycle process.

This research aims to describe the analysis of students' creative thinking in posing SPLDV problems in terms of students with high abilities and low abilities. This research is a qualitative descriptive study. The material used is Systems of Linear Equations in Two Variables (SPLDV). SPLDV are two linear equations that have solutions in the form of ordered pairs which can be represented by x, y. The results of the research are that students with high abilities in asking SPLDV problems can be included in the good category. Students with medium low ability in asking SPLDV problems are still in the sufficient category. Low ability students HY are only able to meet the indicators of creative thinking fluency. In planning and implementing SPLDV problem submissions, it is seen from cognitive ability, namely high ability and low ability are still categorized as lacking.

Saat ini sudah banyak perusahaan yang bergerak diberbagai bidang sehingga persaingan antar perusahaan terjadi semakin ketat dalam mendapatkan keuntungan. Banyak cara yang dilakukan oleh suatu perusahaan untuk meningkatkan pendapatan, salah satunya adalah dengan memberikan target penjualan suatu produk paket Internet kepada karyawan bagian sales.Pengadaan sales dapat dilakukan melalui perusahaan alih daya (outsourcer) dan diberikan target penjualan dengan tujuan untuk memaksimalkan keuntungan perusahaan dan insentif sales. Artikel ini bertujuan untuk menentukan jumlah target penjualan yang didistribusikan kepada beberapa tingkatan sales, agar diperoleh insentif maksimum. Perolehan insentif maksimum bagi sales menunjukkan tingginya tingkat penjualan yang mana dapat meningkatkan keuntungan bagi perusahaan. Untuk menentukan distribusi penjualan paket Internet yang optimal, maka digunakan metode Simpleks, yaitu salah satu metode penyelesaian dalam program linier sebagai teknik pengambilan keputusan untuk mencari nilai optimal. Melalui metode simpleks dilakukan analisis untuk mengetahui alokasi jumlah penjualan paket Internet perbulan oleh sales yang optimal. Metode pengumpulan data dilakukan dengan teknik wawancara dimana pengolahan data dibantu dengan aplikasi QM For Windows. Hasil dari penelitian menunjukkan jumlah alokasi paket Internet yang harus dijual per bulan oleh tiap tingkatan sales agar dicapai target optimal sehingga meningkatkan insentif para sales dan juga meningkatkan keuntungan perusahaan.

This research aims to describe the profile of students with high, medium and low mathematical abilities in solving word problems on flat shapes. This study used descriptive qualitative method. Supporting instruments include mathematical ability tests, problem solving tests and interview guides. The data obtained from this research are the results of students' mathematical ability tests and the results of mathematical problem solving tests in the form of story questions, both written tests and interviews. The results of this research are that students with high mathematical abilities in understanding problems, planning solutions, carrying out solutions and re-examining problem solving are included in the good category. Students with moderate abilities in understanding problems are quite good, in planning solutions they are quite good, in carrying out problem solving plans they are in the poor category and in re-examining solutions they are not good enough. Students with low mathematical abilities in understanding problems are in the fairly good category, in planning solutions are quite good, while in carrying out and re-examining problem solving they are in the not so good category.

Mathematical modeling is the process of deducing a mathematical model of a phenomenon based on the assumptions used. The purpose of a mathematical model is to make decisions based on real situations by analyzing the model. This research aims to obtain a mathematical model of income for KUD Karya Bhakti Pamekasan, to determine the most dominant variables influencing income and to determine the perception of the Karya Bhakti village community regarding income and progress of KUD in the area. The method used in this research is a quantitative method. Data collection techniques through literature study. Data analysis uses linear regression analysis to obtain a mathematical model, namely Y=228961 935 - 0.197x e. The constant is 228961935, which means that if income (Y) is non-existent or zero (zero), then the SHU (Y) in the cooperative will decrease by IDR 289,61,935. Meanwhile, the b value (regression coefficient) shows a negative value of 0.197. A value of 0.197 means that if income is zero then the SHU remains the same and every additional 1 sale reduces the SHU by 0.197.

The mathematical model of infectious disease spread used in this study is the SEIT (Susceptible Exposed Infective Treatment) type epidemic model with a saturated incidence rate. Optimal treatment control is given to the exposed and infective populations with the same treatment rate with the aim of minimizing the number of infective individuals and treatment costs. By applying the Pontryagin Principle, optimal control and system are obtained. The rate of population change in the model is illustrated by numerical simulations.

Seorang guru profesional sebagai landasan pendidikan diharapkan tidak hanya menguasai materi sesuai bidang keilmuannya, tetapi juga mampu mengelola pembelajaran dengan baik dan memiliki keterampilan berbahasa yang berkelanjutan, salah satunya adalah menulis. Karakteristik tuturan tulis akan berbeda dengan tuturan lisan karena disampaikan tanpa berkomunikasi secara langsung dengan lawan bicara sehingga diksi, struktur kalimat, sintaksis, morfologi, ejaan, dan bentuk tulisan perlu diperhatikan. Oleh karena itu, diperlukan pelatihan dan praktik yang berkesinambungan untuk meningkatkan pemahaman dan pembiasaan dalam keterampilan menulis, khususnya menulis surat dinas. Metode yang digunakan dalam pelatihan penulisan surat dinas bagi guru TK adalah ceramah, demonstrasi, dan praktik. Hasil dari kegiatan ini adalah adanya peningkatan kemampuan guru dalam menulis surat dinas. Indikator keberhasilan pelatihan ini diidentifikasi dari dua kategori yaitu respon positif dari peserta dan adanya peningkatan kemampuan guru TK dalam menulis surat dinas.
