Abstract

There is a value of Riemann integral from a function that cannot becalculated. In this case, approximate method can be used to interpret the value.One of the approximate method of integral Riemann is tangent line method that isa compound method between the sum of Riemann and trapezoid method. Thetangent line method uses the tangent line approach. In this writing, the topicdiscussed is the tangent line method in deciding the approximacy of Riemannintegral of a function.

Abstract

Bunga melati putih memiliki potensi ekonomi dan social yang besar bagi masyarakat Indonesia khususnya dan dunia umumnya. Kebutuhan melati putih terus meningkat, namun produksi bunga melati putih di Indonesia baru mampu memenuhi sekitar 20% dari kebutuhan melati di pasaran dunia. Untuk itu diperlukan upaya untuk meningkat kuantitas dan kualitas produksi bunga. Pemanfaatan Zat Penghambat Tumbuh merupakan salah satu solusi untuk meningkatkan produksi bunga melati putih. Salah satu Zat Penghambat Tumbuh yang biasa digunakan adalah paclobutrazol. Sehubungan dengan itu maka dilakukan penelitian dengan judul “ Induksi Pemekaran Bunga (Anthesis) Tanaman melati putih (Jasminum sambac L. W. Ait) dengan pemberian paclobutrazol pada beberapa konsentrasi. “ Penelitian ini dilakukan pada bulan Maret sampai Juni di greenhouse STKIP PGRI Sumatera Barat. Rancangan  percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) yang terdiri dari 6 perlakuan dan 4 ulangan.  Terdiri dari perlakuanA= control, B=200 ppm, C=400 ppm, D= 600 ppm, E= 800 ppm, E= 1000 ppm. Hasil penelitian menunjukkan bahwa pemberian paclobutrazol pada beberapa konsentrasi tidak memberikan pengaruh terhadap waktu muncul kuncup bunga, waktu mekar bunga (anthesis), dan jumlah bunga melati putih

Abstract

Student difficulties in understanding the logarithm material is one of the reasons for developing student’s worksheet of Elementary Algebra for logarithm material. Another factor is that there has been no effective teaching materials that facilitate the students in the lecture. The existing reference books only convey information and have not been able to construct knowledge of students, so that they do not understand about the concept. The purpose of this research was to develop a valid student’s worksheet of Elementary Algebra subject in STKIP PGRI, West Sumatra. This research is a research development. Model of development in the research used procedural models for Instructional Development Institute (IDI). Validity was analyzed by the expert of Elementary Algebra. Once the module is validated by experts, it is obtained that the student’s worksheet of Elementary Algebra valid
