MEDIA UNTUK MENGEFEKTIFKAN PEMBELAJARAN OPERASI HITUNG DASAR MATEMATIKA SISWA JENJANG PENDIDIKAN DASAR

Abstrak. Matematika yang bersifat abstrak menjadi salah satu penyebab siswa-siswa pada jenjang pendidikan dasar mengalami kesulitan dalam belajarnya. Anak-anak usia sekolah dasar masih berada dalam tahap berfikir formal, segala sesuatu dihubungkan pada sesuatu yang kongkrit. Pembelajaran matematika yang abstrak menyebabkan siswa SD yang berada pada tahap berfikir konkret memerlukan alat bantu berupa media dan alat peraga yang dapat memperjelas apa yang akan disampaikan oleh guru. Segala aspek yang dapat menunjang terciptanya pembelajaran yang efektif seperti media pembelajaran perlu dipersiapkan guru disesuaikan dengan karakter siswa di kelas. Metode yang digunakan dalam penelitian ini adalah metode documenter. Terdapat beberapa media yang telah diciptakan dan terbukti dapat meningkatkan keaktifan guru dan siswa yang berhasil, serta dapat pula meningkatkan hasil belajar siswa pada materi Operasi Hitung Dasar Matematika, diantaranya Gambar Tempel Berwarna, Wayang BILBUL,  Mistar Hitung, Alat Peraga Muatan Listrik, Kartu Bilangan, dan Koin Hitung. Kata Kunci: media, efektifitas pembelajaran, operasi hitung dasar matematika

ANALISIS DUA KONEKSI PELANGI PADA GRAF HASIL OPERASI PERKALIAN KARTESIAN GRAF KIPAS F_(1,3) DAN GRAF LINGKARAN C_n SERTA KAITANNYA DENGAN KETERAMPILAN BERPIKIR TINGKAT TINGGI

Abstract. The rainbow connection of the graph of G = (V, E) if for each pair of points u and v in G there is a path with points u and v as the end points on each side obtaining different colors, the path is called the rainbow path. The rainbow-connected number graph G is the smallest positive integer such that G has a rainbow connection staining denoted rc(G). While the graph is said to be a rainbow 2-connected staining on G if for each pair of points u and v on the sides there are 2 different paths, with u and v being the end points of each side obtaining different colors and 2 passages can not intersect each other, denoted rc2 (G). Let G be the graph connected with  so that , with d is degrees. Let G be a rainbow   so that where κ is the number of paths of rainbow connecting every two distinct points in G. The results of this research are new theorem about the rainbow connection and 2-rainbow connected.   Keywords : rainbow connection, 2-rainbow connected, rainbow pat

OPTIMALISASI KEUNTUNGAN PADA PRODUKSI TEMPE DENGAN PENERAPAN LINEAR PROGAMMING DI KECAMATAN BANJAR KOTA BANJAR JAWA BARAT

Soybean is one of the main food commodities after rice and corn. Tempe is a traditional food made from soybeans. Tempe is widely produced by small and medium industries. This study aims to determine the maximum benefits obtained in the District of Banjar, Banjar City, West Java Province in producing tempe. This type of research is a descriptive study with a qualitative approach.  By using the probably sampling method, take a random sample. Determination of the sample is taken in 3 tempe productions with different tempe production income. By determining the decision variables, objective functions, and constraint functions by linear programming methods. In Tempe production in the Banjar District, Banjar City, West Java, the maximum profit was Rp. 29.257.080 and the maximum income was Rp. 28.862.790. The maximum profit and income are obtained from a large workforce so that it can produce a lot of tempe production and the cost of depreciation of the tool is small. The more tempe production, the more revenue obtained. &nbsp

IDENTIFIKASI AKTIVITAS ETNOMATEMATIKA PETANI PADI PADA MASYARAKAT JAWA DI DESA SETAIL

Abstract. Ethnomathematic is a study done for examines how a group of people in particular culture comprehending, expressing and applying the mathematic concept and use on culture which described mathematically by the researcher. The aim of this research for describing kind of ethnomathematic activity of Javanese in Setail Village. This research is a qualitative ethnographic approach. How to capture the subject of research by the snowball technique, that is by looking one by one the subject prior to the data obtained experiencing saturation point and limited to 7 farmers.
