Abstract

Diatom is a widespread and cosmopolite micro alga, some can used as bio-indicator of the past environmental change because of its sensivity to its habitat condition and because it is wellfossilized. This study has been done on the estuary of Banjir Kanal Timur Semarang which has ecosystem mangrove; this region is often affected by coast abrasion, flooded by spring-tideinundation water, rain, and freshwater inflow of the river. The study was aimed to examine relative abundance difference, diversity, and vertically variety level of diatom per 2 cm per sediment layer. Sampling method used in the research was “Judgemental Random Sampling”. The result shows that diatom in the mangrove ecosystem of Banjir Kanal Timur Estuary is stable in the upper layer sediment and midle from lower layer and the mangrove ecosystem of Banjir Kanal Timur Estuary is affected by freshwater estuary, based on the domination of the existence of freshwater diatoms (Navicula radiosa, Synedra ulna, Meridion circulare, Sellaphora bacillum, and Eunotia lunula) onthe 8-20 layer.

Abstract

This study aims to know the children's insight toward the existence of school as educational institution and to improve their critical awareness toward the real meaning of education. This study uses descriptive qualitative method for identifying the meaning of school, the impact of that meaning and the implications for the development of the educational system in Indonesia. The results show that school, for children, is defined as the process of knowledge transferring, hence it will be useful to seek jobs. This concept is also supported with schooling-oriented thinking. It means that children have to go to their school in order to meet their duty toward their parents and country. In boarder sense, school (or schooling) works as the representation of socio-cultural phenomenon because it contains such policies and programs issued politically in which the act of those is forced and dominated by the leaders. The effect of these situations is that the children lack awareness of the truly meaning of schooling. It implies that the school children are less good in daily life behaving and less in paying attention and caring of their surrounding environment. Based on those arguments, we need to train the children to act critically and improve their critical awareness so that the school children have good morality and attitude that make them useful for the existence of our nation.
