Abstract

High diversity of plant in University of Jember caused a safe, healthy, and beautiful environment. Almost all the plant are Spermatophyta and have woody form. Spermatophyta is a group of plant that has seed as the main characteristic. The woody plant (arbo) is a plant that has stem from wood, big form, and various type. This research aimed to know the kinds of Spermatophyta around Jember University. This research was included as a qualitative descriptive research, which is carried to drawing, interpretating and describing data systematically, factual, and accurate about the facts and the characteristics of Spermatophyta around of University of Jember. The research design contained location the selection of research location, sample and picture taking, and plant identifying. The method of sample taking was cruise. There were 4.644 of Spermatophyta that already found, that contained 80 species and grouped on 32 families. These families were Anacardiaceae, Annonaceae, Apocynaceae, Araucariaceae, Arecaceae, Bignoniaceae, Burseraceae, Calophyllaceae, Casuarinaceae, Combretaceae, Cupressaceae, Ebenaceae, Euphorbiaceae, Fabaceae, Flacourtiaceae, Gnetaceae, Lamiaceae, Lauraceae, Lecythidaceae, Lythraceae, Magnoliaceae, Malvaceae, Meliaceae, Moraceae, Muntingiaceae, Myrtaceae, Oxalidaceae, Phyllanthaceae, Pinaceae, Rubiaceae, Sapindaceae, and Sapotaceae. Keywords: Identifying, Spermatophyta, University of Jember

Abstract

One of learning models that can involve the active student in the learning process is Learning Cycle (4E). The results obtained by applying the Learning Cycle (4E) method is the increase of the activity of learning, in pre-cycle the result obtained 53,14% (less active criteria) increased to 62,08% (quite active criteria) in tha first cycle and in the second cycle increased to 75,38% (active criteria). The results obtained in the classical learning increased in pre-cycle (6.67%), to the first cycle (43.33%) and the second cycle (70%), then the aspects of affective is 75.33% in the first cycle, and increased in the second cycle to 77.46%. In the psychomotor aspects it raise to 71,67% that increase in the first cycle meeting 2 and increased to 77,5% in the second cycle of the meeting 2. So we can know that Learning Cycle (4E) method can improve the activities and the outcome of learning process based on the results. Keywords: student activities, the result of learning, Learning Cycle (4E) model.

Abstract

Piper is a genus of the family Piperaceae which has a very large number, in the tropics and sub-tropics. There are about 22 species of Piper which are registered in medicinal herbs and world herbs, one of which is Java chili (Piper retrofractum Vahl.). The morphological characters of P. retrofractum are different in various planting centers, especially the leaf and fruit characters vary. Limitations of morphological characters encourage the use of molecular characters. The purpose of this study was to analyze the molecular character of Java chilli (P. retrofractum) on the island of Java using ISSR (Inter simple sequence repeat) markers. Molecular markers can provide relatively more accurate information because genetic traits tend to be stable in environmental changes and not influenced by age. Leaves from 12 different locations were isolated using the SDS method. Amplification was carried out using 12 ISSR polymers. Data is analyzed using the NTSYS version 2.02 program. The results showed that the amplification of P. retrofractum DNA produced 70 polymorphic DNA bands. The dendrogram results from 12 sampling locations showed that P. retrofractum on Java Island had a similarity coefficient of 0.69-0.93. This shows that genetic diversity based on ISSR markers from P. retrofractum Vahl is relatively low.
