Abstract

From the stand point of carbon dioxide cycle on global warming, the conversion of CO2 into various useful carbonic material compound is one solution. Using natural energy sources such as LNG and cole may contribute to CO2 removal in the atmosphere. As one of feasible measure though CO2 is final oxidized product of carbon containing reaction have been proposed and investigate. Biological proces have to developed, CO2 was efectivly converted to methan, acetat, and raw material for plastic degradable.

Abstract

The green revolution in the 19th century, has met expectations in an effort to increase the productivity of food supply, in the world at least in Indonesia. In the course of time the green revolution movement has given the systemic impact not only on the degradation of ecosystems, but also the productivity of land, especially paddy fields due to the use of agrochemicals that have been over threshold. The impact on soil in Indonesia become ill, there is a change of soil structure, become poorer and finally lost as the land carrying capacity of production. Systemic Degradation covering 18 000 ha of wetland, contamination levels of heavy metals such as Hg, Fe, Cd, Cu has been on conditions that endanger human health also pesticide has an impact resistance to pests.Recovery efforts of agricultural land, will take time, and cost is not cheap. Various studies have been done, to remediation land by using acid-humic substances, and gives results quite encouraging, because it’s quite effective, efficient and inexpensive, compared with conventional methods is to provide an organic material such as kompost.

Abstract

Beauveria bassiana is a well known entomopathogenic fungus that has been widely used for biocontrol of many economically important pest of crops. Production technology for massive production of bioinsecticide B. bassiana still using liquid fermentation. Product formulation is the critical stage for producing bioinsecticide B. bassiana, since its success indicator is the contain of viable propagules in the final product after long period of storage. The aim of this study is to assess the optimal production of biomass and formulation of bioinsecticide B. bassiana. Result showed that the best production technology of bioinsecticide B. bassiana is by liquid fermentation, as an innovative method aimed to reduce the production cost. Assessment of formulation of bioinsecticide B. bassiana showed that formulation using simple raw materials to make a pasta without filler is the best choice to be further developed.
