Analisis Kemampuan Mahasiswa Pendidikan Guru Sekolah Dasar Fkip Universitas Riau dalam Pengukuran Keliling dan Luas Bangun Datar

The purpose of this study is to analyze student teachers at Primary School Teacher Education of RiauUniversity in understanding the concepts of measurement perimeter and area. The reason in doingthis research is that many student teachers usually use formal formula in solving measurementperimeter and area. They will do the same thing when they teach Primary School Students, so thestudents will not know how the formula works. Design research was chosen as a method in gettingdata. The data were collected from 48 student teachers at Primary School Teacher Education of RiauUniversity. The result showed that six out of ten group of student teachers did not use partitioning inthe beginning of the lesson. They also made a mistake in measuring the perimeter of unstructuredshapes. After classroom discussion, 96% student teachers came to the idea of partitioning. It meansthat they realized the important of partitioning in measure the area of unstructured shapes

Karakteristik Geokimia Organik Fraksi Hidrokarbon Alifatik Batubara Sawahlunto, Cekungan Ombilin, Sumatra Barat

Batubara Sawahlunto, Sumatra Barat dianalisis untuk menentukan karakter geokimia organiknya melalui metode ekstraksi dan identifikasi sehingga dihasilkan fraksi hidrokarbon alifatik. Fraksi hidrokarbon alifatik kemudian dianalisis dan diidentifikasi strukturnya menggunakan Kromatografi Gas – Spektrometri Massa (KG-SM). Identifikasi struktur menunjukan adanya distribusi n-alkana dan isoprenoid. Senyawa n-alkana terdistribusi unimodal mulai n-C15 sampai n-C33 dengan dominasi rantai panjang (>C20) yang mengindikasikan senyawa organik batubara berasal dari tumbuhan tingkat tinggi. Rasio pristan terhadap fitana > 3 menunjukan lingkungan pengendapan yang oksik. Kedua sampel memiliki nilai LHCPI < 1 menunjukan bahan organic berasal dari tumbuhan tingkat tinggi. Kedua sampel memiliki nilai CPI > 1 menunjukan batubara Sawahlunto belum matang. Hasil analisis kalori dengan Bomb Kalorimeter terhadap sampel batubara yang dianalisis menunjukkan sampel tergolong ke dalam peringkat sub-bituminous

A framework for a comparative study of pre-service elementary teachers’ knowledge of rational numbers

This paper presents a framework of a PhD research of the first author about a comparative study of pre-service elementary teachers’ knowledge of rational numbers between Indonesia and Denmark. To obtain the data, the authors design a series of hypothetical teacher tasks (HTTs), inspired by a paper of Durand-Guerrier, Winsløw, and Yoshida (2010). Subjects in this research are pre-service elementary teachers from a selection of different University Colleges in Denmark and from the elementary school teacher education study program, Riau University, in Indonesia. The praxeological reference models and the levels of didactic codetermination are used as tools to analyse the result
