Abstract

Diatom Epipelik memiliki arti penting dalam sedimen mangrove karena merupakan komponen utama mikroalga yang mengandung klorofil, sehingga klorofil dalam sedimen akan mempengaruhi produktivitas primernya. Nilai kandungan klorofil -a dalam sedimen di kedalaman 2 cm berkisar antara 0,125 - 0,405 ?g/cm3 menunjukkan bahwa pada kedalaman 2 cm mempunyai kandungan klorofil -a tertinggi bila dibandingkan pada kedalaman sampling 4 cm ataupun 6 cm. Untuk parameter fisika - kimia oseanografi, kondisi lingkungan memiliki kecenderungan yang normal.Kata kunci : klorofil -a, sedimen mangrove, produktivitas primer.The result showed that Epipelic Diatom have an important role in mangrove sediment, since they are known as major component of microalgae which containt chlorophy. These chlorophyll influence the level of primary productivity, within the sediment. The highest chloropyll a content within sediment was found in those taken from 2 cm deep range, compared with those taken from 4 cm and 6 cm deep.Key words : Chlorophyll -a, mangrove sediment, primary productivity.

Abstract

Millennial generation of Merapi Slopes view that the eruption of Mount Merapi is a natural cycle, so they are required to be able to adapt to the natural environment. It is a necessity to increase the capacity of millennial generation in the context of disaster management. SMPN 2 Karangnongko applies the Smart School extracurricular in order to disseminate the values of peace and disaster management. The purpose of this study is to describe the perception of millennial generation towards disaster and the effect of the application of Smart Schools on capacity building. The study uses qualitative methods with data collection methods of observation, interviews and documentation. The results showed that the perception of millennial generation in Logede region towards disasters as tragedies, ordeal, tests, and unpleasant events that brought misery. This view is influenced by religious values and local wisdom that develops in the community.
