Abstract. The Amazon Basin provides an excellent environment for studying the sources, transformations, and properties of natural aerosol particles and the resulting links between biological processes and climate. With this framework in mind, the Amazonian Aerosol Characterization Experiment (AMAZE-08), carried out from 7 February to 14 March 2008 during the wet season in the central Amazon Basin, sought to understand the formation, transformations, and cloud-forming properties of fine- and coarse-mode biogenic aerosol particles, especially as related to their effects on cloud activation and regional climate. Special foci included (1) the production mechanisms of secondary organic components at a pristine continental site, including the factors regulating their temporal variability, and (2) predicting and understanding the cloud-forming properties of biogenic particles at such a site. In this overview paper, the field site and the instrumentation employed during the campaign are introduced. Observations and findings are reported, including the large-scale context for the campaign, especially as provided by satellite observations. New findings presented include: (i) a particle number-diameter distribution from 10 nm to 10 μm that is representative of the pristine tropical rain forest and recommended for model use; (ii) the absence of substantial quantities of primary biological particles in the submicron mode as evidenced by mass spectral characterization; (iii) the large-scale production of secondary organic material; (iv) insights into the chemical and physical properties of the particles as revealed by thermodenuder-induced changes in the particle number-diameter distributions and mass spectra; and (v) comparisons of ground-based predictions and satellite-based observations of hydrometeor phase in clouds. A main finding of AMAZE-08 is the dominance of secondary organic material as particle components. The results presented here provide mechanistic insight and quantitative parameters that can serve to increase the accuracy of models of the formation, transformations, and cloud-forming properties of biogenic natural aerosol particles, especially as related to their effects on cloud activation and regional climate.

Arjowilangun Village is a post-TKI village. People choose to become sheep farmers with less capital than being cattle farmers. Based on the previous discussion, waste management is required to ensure the sustainability of environment in Arjowilangun Village. Processing sheep and agricultural waste program is held by Doktor Mengabdi team. Farmers can learn how to make Bokashi from waste. The method used is composting aerobic or anaerobic starters for composting organic material. A decomposer as collection of several good microbes from fungi work to control pathogenic microbes assists the fermentation process. Based on the results of the pre-test and post-test during the training, it can be showed that understanding of the breeders' potential of the environment is increased.

Subsequent Regeneration

Seawater contains high amounts of organic material and ions causing high salinity.The distribution of nutrients in the ocean is determined by ocean circulation, biological processes of uptake and mineralization, and subsequent regeneration of nutrients by migration of animals and by supply from the land.Topic related to sea water is important to discuss and to be a challenging with many researchers in Indonesia. In this paper, organic mater from sea water was learned in detail. The information contained of formulation history, justifi cation, distribution, advantages, and method of measure, type and effect to environment.Keywords: organic material, sea water, dissolved
