Global warming will have a negative impact on biodiversity. In contrast,the increase of population in the world has an effect to the need ofbiological resources for food, industry, medicine, etc. Human activitiesin several sectors, such as energy, forestry, agriculture, husbandry,and waste create a greenhouse effect. Greenhouse effects are due to arise of greenhouse gases, such as CO2 (carbon dioxide), CH4 (methane),N2O (nitrogen dioxide), PFCS (perfluorocarbon), HFCS (hydrofluoro-carbon), SF6 (sulfurhexafluoride), and H 2O (water vapor). Studiessuggest that climate change may also cause the melting of polar ice-caps, rising sea levels, and a shift of season. Global climate changewiil also have a wide range of effects on human health, including a riskof infectious disease epidemics. Therefore, climate change is a seriouslythreat for the world and it is necessary to have a global agreement tocombat the threat. In 2005, Kyoto Protocol was agreed and The CleanDevelopment Mechanism (CDM) is a the Kyoto Protocol’s mechanismaimed at helping industrialized countries meet their greenhouse gasreduction targets. The CDM is also meant to help developing countriesachieve sustainable development, including facilitating the transfer and/or development of low-emission technologies. Long term collectiveefforts are needed to combat and adapt with adverse effects of globalwarming, especially for the extinction of biological diversity.

Up until now, some countries still facing food shortage. One of thereasons is waters carcity. As we know, it is estimated that 70 percentof the water consumed worldwide, including that diverted from riversand pumped from underground, is used for irrigation, while some 20percent is used by industry and 10 percent for residential purposes. Inthe increasingly intense competition for water among these three sectors,the economics of water do not favor agriculture. In China, 1,000 tons ofwater can be used to produce 1 ton of wheat, worth perhaps $200, or toexpand industrial output by $14,000—70 times as much. In a countrythat is desperately seeking economic growth and the jobs it generates,the gain in diverting water from agriculture to industry is obvious.

Tampomas mountain areas can be divided 2 types of aquifer : volcanosediment aquifer and sediment aquifer. Volcano sediment aquifer is afree aquifer sedimentation, because there was not impermeable rockexisting under or bellow it, this aquifer also known as shallow or surfaceaquifer. Sediment aquifer is a depressed aquifer where the water flowalong the sandstone layer which covered by claystone and water flowthrough the pore. This sediment aquifer are deep aquifer. Ground waterat sumedang area can be divide as : ground water on volcanic quartersedimentation and ground water on consolidate rock.The type of water source at the reaserch area can be devide into 3 ways: Depressed water resources formed by land surface which is cuttingthe watter table, Shear water source which formed by the crack / shearstructure or sesar path, and contact water source which shown at thetertiery rock (impermeable) and quartery rock (permeable).This reaserch using geofisical methode Imaging Resistivity to resultinterpretation that on the south Tampomas Mountain predicted had 4aquifer potention resource (A,B,C,D), whith aquifer thickness vaariatedfrom (5-15)m, (30-50)m and more than 50 m. Several water sourcesurface cases found in this reaserch area at 20-30 m depth which predictas the water table. This indicated there are very large aquifer at 500 mlevel and assume this level as a potential places for ground water existat the south Tampomas mountain.

Historically, the health of aquatic systems was monitored primarily through chemical means. However, chemical monitoring provides only a "snapshot" of conditions at the time of sampling and may fail to detect acute pollution events (e.g. runoff from heavy rain, spills), non-chemical pollution (e.g. habitat alteration) and non-point source pollution. In order to address the shortcomings of chemical monitoring, the biological monitoring could be used and more accurately reflect the health of ecosystem. Biological monitoring is based on the premise that biological communities are shaped by the long-term conditions of their environment and more accurately reflect the health of an ecosystem.

Pollution in the rivers is generally caused by domestic and industrial waste.Some treatments to solve it can be done individually or collectively. Theeffort can be physical, chemical, or biological treatments chosen by itsform, character, kind, quality, quantity. PT Van Melle Indonesia is a candycompany which produces a high biological waste with COD concentration10000-30000 mg/litre. This paper reports activated sludge reactorperformance to decrease the waste’s organic content. The reactor is abiological waste water treatment, as a sequence of earlier anaerob processwhich still has a high COD (700-4000 mg/litre). A continued reactoroperation done with retention time variation 24 hours, 18 hours, 12 hours,and 6 hours show reduced COD varied 80-90%. The highest efficiencywas 97.59% from the 24 hours retention time, and the lowest efficiencywas 89.5% from the 6 hours retention time.

Indonesia still using common and control (CAC) instruments in controllingenvironmental problems. Law No 23 year 1997 and decree of the ministerand others regulations related to the law were established based ontop-down policy approach. Environmental problems in most cases areeffective to be controlled using common and control policy, however inissues of pollution or emission control, economic instrument or marketbased instrument is effective compare to the CAC. Another reason isflexibility of the instrument. This empirical study is intended to analyzehow an instrument economy is useful in controlling CO2 emission. DICEmodel (Dynamic Integrated and Climate Change Economic ) or sometimecalled Three–Box model system is one of economic models which isused for controlling CO2 emission in response to potential threat ofglobal warming. Emission of CO2 from fossil fuel is taxed throughoptimation of the model. Emission control rate is policy variable. Modelsystem equations are solved using General Algebraic Modeling System(GAMS). Optimum scenario is occurred where value of rate of socialpreference 5%. Model outcome suggest that abatement cost havingrange between 0.1-6.7% of GDP and reduction of emission in range of20 - 80% of current emission rate for the period of 1990-2019. In optimalcondition, model suggest that appropriate emission tax for fossil fuelhaving range of 0.002 – 0.024 USD per liter or equivalent to 3.90-40.35USD carbon tax per ton of fossil fuel coal having range 1,95 -20,25USD per ton CO2.

This report summaries the results of sampling (and analyses) of stack flue gas of P.T. Semen Cibinong’s Kiln, located at Jl. Raya Narogong, Desa Nambo, Cileungsi, Bogor. The test was aimed to determine concentrations of emitted metals (As, Cd, Cr, Pb, Hg and Tl) concentrations. The conditions of the kiln tested were maintained at its normal operation. The metals were sampled from the flue gas at 3 (three) replicates. The metals concentrations in all three tests were well below the standard as stipulated in Kep-06/BAPEDAL/02/1999. This stack sampling work was carried out with the strict procedures specified by United States Environmental Protection Agency (US-EPA), Method No. 29. The laboratory analysis of metals were conducted by Analitika Sejahtera Lingkungan (ASL) laboratory, Bogor. The procedures of both stack sampling and laboratory analyses have followed a quality assurance/ quality control (QA/QC) program as an integral part of the overall technical effort.

The agroforest region is bestowed with diverse agro-climatic zones, whichmakes itself a rich storehouse of different types of Flora and Fauna.Besides, this conditions help in introduction, acclimatization, andcultivation of a number of aromatic plants with minimum efforts. Thereare a few commercial crops, which can be cultivated without disturbingthe existing flora and have the potential to establish as cash crops inthis region.Patchouli (Pogostemon cablin) has been identified as one such essentialoil bearing aromatic plant with immense export potential. Patchouli oilproduction could be a rural based, labour intensive, low cost agro-basecottage industry, which will give large-scale employment in rural and hillyareas. Patchouli, being a shade loving plant can easily be grown as anintercrop amidst fruit trees, arecanut, and coconut plantation etc. It canalso be easily cultivated in flood free fallow or wastelands. This will providesome extra income for the farmers. Following figures clearly indicatesthat Patchouli cultivation can be a good option besides the traditionalcrops.

In the process of decomposition of the organic matter with the anaerobicsystem was learnt that the methane forming bacteria of was verysensitive to the level of the acidity in other words very sensitive with thelow pH. There are by two big groups the bacteria that was active in thissystem. These two bacteria group had the duplication capacity thatwas very different that is 3 hours during the acid forming bacteria of and3 days for the methane forming bacteria. The alkalinity in the reactorwith the certain concentration between 1000 – 5000 mg/l could supportthe pH continue to in the neutral condition when the decline in the pHhappened so as the balance of the process could on the whole stayproceeding normally.It was observed that achieving the pH 3 in the feeding, the concentrationof the alkalinity descended through to 500 mg/l this was the loweredcondition and the process of decomposition of the organic matter wasdisrupted. When being left alone then the system will stop completelybecause of the methane forming bacteria was inhibited.

This article contained several differences of the theory about anaerobicsludge granulation biogas in the UASB reactor. The level of the granulationformation of the beginning followed same principles as the formation bio-film from the bacteria to a surface field. There exist strong facts that thematerial inert played a positive role important and granulation. Mostresearchers took the conclusion that Methanosaeta concilii was the mainkey to the formation of granulation. Only Town Stamp hypotheses thatassumed that the organism autotrophic hydrogenotrophic like for exampleMethanobacterium from strain AZ, could grow in the condition high H2-pressure, was the key to the formation organism of granulation. Severalwriters focus in the stage granulation early and only several contributionsthat discussed the following stage in granulation included maturationgranulation and multiplication. Determining factors granular in the latterstage was dominated in the existence of the manipulation of the pressureelection, through which particle of bigger sludge selectively was kept inthe UASB reactor.
