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.

Fixed Bed Reactor was the biological wastewater treatment reactor thatwas one of the Cakung Slaughterhouse (RPH Cakung) wastewatertreatment. Biological wastewater treatment process in principle wasprocess use of the microorganism to degrade the wastewater pollutant,where the wastewater will be changed into gas and the particle bio-solidthat enabled to be sediment. The capability of the microorganismdegrading this pollutant was influenced by various factor, some amongthem were the distribution of the substrate (microorganism group) inthe reactor. The distribution of this substrate could be known bymeasuring the value of pH and organic content as Chemical OxygenDemand (COD) or Total Solid (TTS). Considering the importance of theparameter then must be keep so that both of them, did not exceedlimits that were allowed in the FBR operation. This paper was discussedby the condition for the distribution of the substrate in various hydraulicretention time (HRT). Analysis was held for the operation with the up-flow system. Results of the research could be known that the value ofthe pH and TS in various HRT relatively constant, that is between 6.93– 7.15 (for the pH) and 0.32% - 0.56% (for TS). This value is still inlimits that were allowed. This showed that the FBR reactor had thegood performance was inspected from the condition for the distributionof the substrate inside.

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.

In the year of seventienth where the energy crisis struck the world, thecompeting person looked for the alternative to energy change the sourceof conventional energy (petroleum). One of the topics that it was hopedbecame alternative was BIOGAS from the process of the anaerobicfermentation of organic matter either agricultural or food industrial waste.Several parameters were studied to prove that anaerobic fermentationof the solid organic matter could become the BIOGAS as alternativeenergy replaced petroleum. Currently these all ideas were remains atthe myth completely.The reality from investigation of the technology degradation process /digestion of the organic matter by making use of this anaerobicfermentation system was only could be used as one of the wastetreatment as the solving problem of pollution of the environment, withresults of taking the form of BIOGAS that could be made use of assubstitution energy for the waste treatment it self. In other wordsanaerobic fermentation technology of the solid waste was one of thesolid waste treatments with minimal energy. Energy that was needed forwaste treatment process will be produced from himself to substituteenergy that was used from the network of the public (PLN). So as to behoped energy that usually is taken from the national net (PLN) for theprocessing of waste could be reduced, and was subtituted with energybiogas that was produced by him.

Public awareness on environmental protection is getting better now. This condition has also rise in a company own by Province Governmental of DKI Jakarta Raya in the field of slaughtering cattle. This company, namely Cakung Slaughterhouse stay in Jakarta Timur is more a public services instead of a private company. On the waste and wastewater handling as the by product of all activity in Cakung Slaughterhouse, an assessment and development of handling waste and wastewater was carried outcooperation with German agricultural research institute (Bundesforschunganstaltfuerlandwirschaft – FAL) through on the job training, design and engineering of the waste and wastewater treatment plant that would be developed. The training was done by handling the waste of German slaughterhouse as a case study in Germany that has no experience in it on a Cooperation Project of Biological Waste and Wastewater treatment – BTIG Project. Fortunately, beside the technologyand system on waste and wastewater handling, also getting the high awareness in condition for a healthy circumference of life need. Make this project as basic of design on waste and wastewater treatment plant of a slaughterhouse, at least on the essentials organic waste treatment mode.

Anaerobic fixed bed reactor is a fermentation anaerobic reactor used microorganism attached growth system, where degradation of organic material done by microorganism that growth in support material as fixed film. This system mostly used for organic wastewater treatment now. The assessment is carried out for the Slaughterhouse wastewater treatmentwhere the support material for microorganism growth is a fabricated media. Plant is a demonstration scale by digester volume of 600 m . Wastewater is feeding to the digester by up flow system. The wastewater pumped from the bottom of the digester, flow through the support material, contact with the microorganism fixed on the media. Degradation of the organic waste process is take place along wastewater contact with the fixed film.Observation is on the performance of the reactor by the influence of organic loading to the pollution degradation of slaughterhouse wastewater called reactor efficiency. Fixed Bed Reactor performance still reached until 3 days hydraulic retention on organic loading rate about 3.05 kg COD/m hr, and efficiency 75 %.
