The title of the research was "The morphology of pollen of Familia Poaceae at Syiah Kuala University in Banda Aceh". The purpose of this study was to know the morphology of Poaceae allergenic. The microscopic pollen preparat was made by acetolysis method. The data were collected by using descriptive methods and photos. Pollen microscopic preparat was made by acetolysis method. The data were collected by using descriptive method and picture. The parameters used in this research were unit, shape, aperture, sculpture, and allergenic types of the pollen. The result showed that there were 30 species of grass from familia poaceae. The pollen unit was all monads, its shape was subspheroidal, the size was varied magna, media, and minute +, its apertures were tricolpage and monoporate. Its sculpture has psilate, acabrate, and bverrucate. Looking from its sculptur, the pollen was allergenic.

Abstract

The aims of this study to determine the improvement of students' critical thinking skills through the application of learning model the Problem Based Learning in Biology subjects in class X SMA Negeri 1 Kluet Tengah. The subjects in this study were students of class X SMA Negeri 1 Kluet Tengah, with total of 31 students, with focus of this research critical thinking skills ability in Biology subjects. The research design used was classroom action research, which was conducted in two cycles. Each cycle consists of four stages, namely: planning, implementing, observing, and reflecting.
