Abstract

Archiving and dissemination of data , techniques, and observations of Cyanophyta required for optimization of succesfully low plant systematics studies. This paper aims to present the preparation techniques and the results of Cyanophyta algae observing with light microscope and digitaly camera. Sources accurate specimen was also informed by the author repeatedly experience in organizing learning plant systematics. Preparation and microscopic observation Cyanophyta consists of preparation of accurate source of specimens , microscopic observation to obtain optimum picture of the object and focus , shooting or recording images using a digital camera. The image files are stored and are equipped with a scale.Results of preparation , observation and shooting showed that cells and colonies all Cyanophyta (Oscillatoria , Anabaena , Nostoc ) has a similar size range that requires preparation to optimize the use of the same light microscop . Cells of Cyanophyta colonies can be seen clearly in the eyepiece magnification of 10x and 40x objective. Less than that magnification, The thalus of Cyanophyta difficult to observe because of the relatively small cell size compared to the size of eukaryotic cells. By shooting with digitaly camera, microscopy observation images can be captured as digital specimen. Observing the digitaly specimen does not change depending on season and time. The digital images can also be analyzed and studied further. Keyword : microphotography, digitaly specimen, cyanophyta , low plant systematics

Abstract

Education in 21st century is very relevant to the purpose of education in Indonesia. Global era and the integration of technology in education, helped accelerate the synergy of knowledge across disciplines, thus giving birth to a new field. Learning aimed at creating an atmosphere of active, critical, analytical, and creative in solving problems through the development of thinking skills. Science (biology) essentially contains four elements are scientific processes, the product (scientific knowledge), attitudes (scientific attitudes), and technology. Processes in science implies manner or scientific activity for natural phenomena to describe the product obtained in the form of science facts, principles, laws, or theories. Science (biology) containing six elements are active learning, discovery / inquiry activity approach, scientific literacy, constructivism, science, technology, and society, and the existence of truth.There are two things that can be done by LPTK in optimizing the implementation of Curriculum 2013 are: 1) Strengthening understanding of the biology teacher candidates about the nature and characteristics of biology teaching; 2) Creating an academic situation so that prospective biology teachers have insight and knowledge about the importance of the role of science (biology) and as well as the direction of learning in the future. Learning aimed at creating an atmosphere of active, critical, analytical, and creative in solving problems using science process skills Kata kunci: Implementation of K-13, Education in 21st century

Abstract

Learning in UIN Alauddin is still limited knowledge to students, while, one mission to improve the quality of educators Biology in terms of belief, moral and scientific attitudes have not been implemented. This is caused by a lack of learning resources that connects Biology Science and its relation to scientific Quran. Cell Biology as subjects that reveal about the phenomenon of the smallest unit of life, it can be studied with scientific Quran. Therefore, it is necessary to develop teaching materials of Cell Biology with scientific Quran to achieve one mission in Biology Education Courses of UIN Alauddin Makassar to improve quality in terms of the creed of Biology Educators, moral and scientific attitude. Cell Biology purposes of teaching materials even this can help students to better understand the concept of Cell Biology abstract to concrete, because in Cell Biology teaching materials displayed image by using a reference cell that contains the results of research conducted by experts Cell BiologY. Thus, the implementation and achievement of learning objectives can be achieved optimally so that it can support contextual learning of Cell Biology.
