A laboratory experiment on utilization of seaweed-containing solid wastes as media for growing mushrooms was conducted by researchers from the Institute for Environmental Technology. The solid wastes were obtained from PT. Agarindo Bogatama, a food industry which produces jelly powder processed from seaweed of Gracilaria. The company generates 60 tones of solid wastes of seaweed per-day that contained 70% of water content. The solid media was used to grow Auricularia polytricha, Pleurotus astreatus, and Ganoderma lucidum. Some mixed media were prepared with the percentage ratio of sawdust to solid waste as 0, 25, 50, 75, and 100. After sterilizationthe media were planted with mushrooms and then were kept in incubator. After 28-day the basidiomas of G. lucidum was developed while P. astreatus appeared after 36-day of incubation. Both were grown on 100% seaweed media (using 100% sawdust media as a control). This very early results indicated that solid waste of seaweeds have an additional value which can be used as media for mushrooms plantation. Implementation waste to product as a part of cleaner production approach should be disseminated to the industries, especially SMEs like PT. Agarindo Bogatama, who areconcern to the environment.

Because of too many environmental problems have already beencontinuing in Jakarta, the local government of Province DKI Jakarta isintensively doing huge environmental programs in order to cope with theproblems. One of the programs is the application of concept “Ecopark”in managing all of the cityparks or gardens in Jakarta. A lot ofcitygardens in Jakarta have not correctly been managed by the concept,especially gardens which are classified into medium size park. Theaim of this specific program is to optimize the environmental functionof all gardens in the field of water resource management, such asincreasing the efficiency in water resource exploitation, conservation ofthe water resource by rain harvesting and using of treated domesticalwastewater. Content of the assessment in this paper focused on threecitygardens, i.e Cisanggiri, Kelapa Cengkir Barat and Gandaria VGarden. The conclusion said that all the three gardens have an excellentpotential to be developed by the concept Ecopark.

Observation of waste parameter in textile wastewater treatment wasdone. This experimental investigation consist of three mayor textileparameter including total suspended solid (TSS), biological oxygendemand (BOD) and chemical oxygen demand (COD). The parameterswere collected and analyzed. The TSS, BOD and COD consentration ineffluent of textile wastewater treatment is not exceeded the standard,but the efficiency of TSS, BOD and COD reduction is not statisticallysignificant.

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.

BIOGAS SEBAGAI ENERGI ALTERNATIF ANTARA MITOS dan FAKTA ILMIAH Djoko Padmono

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.

Anaerobic digestion of organic waste has some advantages, namelythe recovery of biogas as alternative energy source and the conversionof waste products to soil fertilizer. Compared to mesophilic digestion,thermophilic digestion offers advantages regarding the processperformance and the hygienic aspect. Unfortunately, the process hasgenerally not enjoyed a good reputation because of its poor record withrespect to process stability. Two-stage anaerobic reactor systemconsisting of a hydrolysis reactor and a methane reactor is often usedto overcome such instability problems. In this study, the two-stageanaerobic reactor system is compared to the one-stage anaerobic reactorsystem. This study shows that the two-stage anaerobic reactor systemhas more process stability, can be operated at much more higher organicloading rate, and need much shorter recovery time after a processfailure.

Naturally, the farm damage cure effect of heavy metal waste dismissalwill need very long time, but with growing of knowledge and technologyhence the damage cure acceleratable by passing input bacterium orbioremidiasi into impure land.Organic materials in compost or cage manure have role of vitalimportance in influencing heavy metal availability in land. Organic Manureusage can degrade heavy metal content of chromium at impure landuntil 67 - 68 %. The degradation of heavy metal content in land havecorrelation to level of chromium content to quality of agro product andcrop. Standard gyration quality for chromium content range from 0,5 -1,0 ppm, while chromium content in peanut crop > 0,5 ppm, so that isnot peaceful if exploited for livestock food, but chromium content atseed reside in below standard quality of competent so that to beconsumed, however for certainty have to be seen other heavy metalcontent (cadmium).

Bioconversion technology of agricultural waste or biowaste has beenknown by industries as one of the technology that could provide orincrease quality og fod through industrial food processing. However,some of people in Indonesia have not been realized that uneconomicvalues and unnutritious of agro materials could be converted into highvalue of food and feed, and also usefull material for soil conditionerwhich is improved soil health. In addition, spent mushroom substrateas a waste of mushroom production can be used for a stater material toremediate contaminated soil as one of the strong capability materialfor bioremediation technology for polluted environment. Therefore, thisreview would like to create some hopes for pheasant to covert someagricultural waste materials into useful materials toward povertyalleviation and sustainable community development as mentioned bymillennium development goals. Through this application ofbioconversion and bioremediation technology of agricultural waste whichis ubicuitous in tropical countries like Indonesia, we do much more forenvironmental care and social welfare.
