ABSTRACTCharacterization of Lignite Biosolubilization Products by Indigenous Moulds from Soil ofCoal Mining in South Sumatera. Biosolubilization of coal is a potential technology of convertingsolid coal to liquid fuel and chemicals at ambient condition. Our previous research hassuccessfully isolated four moulds from soil at coal mining - South Sumatera and has potency aslignite biosolubilization agent, i.e. T1, T2, T4, T5. The objective of this research was to characterizeof lignite biosolubilization products by four isolates. The method used was sub-mergedculture. Cultivation medium was MSS+ (minimal salt + sucrose 0,1% + yeast extract 0,01% +lignite 5 %). Incubation was conducted at room temperature for 28 days. The result showed thatall indigenos moulds have different ability in lignite biosolubilization. The highestbiosolubilization occurred after 7 days of incubation belonging to T1 isolate. However, GC-MSanalysis showed the largest percentage of hydrocarbon compound which equivalent to gasolineand diesel was T5 after 7 days of incubation.Key words: Biosolubilization, lignite, moulds, coal.

Most of the rivers’ quality in Indonesia is in highly-polluted status including Ciliwung River in Jakarta. The pollution can affect river ecosystem especially the rivers biota such as plecostomus species that is mostly found in Ciliwung River. The information about correlation between heavy metal and nutrition content in Plecostomus flesh still limited, so the result from this research can give the new information about that. The aims of this research is identifying the effect of the heavy metals towards the contents of protein and fat of plecostomus flesh from Ciliwung River. The analyses methods use X-Ray Fluoresence (XRF) Spectrometer, the analysis of protein using kjeldahl method, and fat analysis using extraction method. The result of this research showed that small-sized plecostomus contained the highest fat and protein compared to medium-sized and big-sized plecostomus. The assumption was the contents of heavy metal which can impede protein and fat absorption. Meanwhile, the content of carbohydrate in small-sized plecostomus was the lowest. The identified type of heavy metal using XRF method was Pb, Hg and Cd with the concentration was higher than the maximum standard (SNI) so that the flesh of plecostomus from Ciliwung River in Jakarta is categorized unsuitable to consumption

Jakarta as one of the biggest city in Indonesia, it own more than 6.506.244 units of motor vehicles. The combustion of fossil fuels in motor vehicles can cause air pollution. Station is represented as one of heavy pollution location. The observation has be done by abservate the amount of vehicles, stomatal characteristic, and weight of dust on Angsana leaves, which growth around Lebak Bulus station. As the result, there is relation between weight of dust on leaf and stomatal characteristic, with r value = 1. The level weighat of dust on leaf has effect to stomata conditions, such as surface of stomata become smaller and shape of stomata become irregular, but amount and size of stomata didnâ€™t influenced. In some case, leaf can be identifid by visible symptoms of injury such as chlorotic at the leaf veins, which caused by SO2 or black or brown flecks at the leaf veins, which caused by NOx.

Lignite coal was found abundant in Indonesia, but usage for this type of coal was still relatively low. Economic value of coal increases when it is solubilized. Biosolubilization of coal by utilize of microbes produces compounds equivalent to petroleum. In this research, effect of urea on lignite biosolubilization by Trichoderma sp. was examined. Method of this research consisted of spore inoculum preparation, biosolubilization lignite coal with a variety of treatment that consists of treatment A (MSS + sucroseÂ 1% + coal 5% + urea), and treatment B (MSS + sucroseÂ 1% + coal 5%). Results showed that the addition of urea supported lignit coal biosolubilization by Trichoderma sp. based on increase in medium pH, concentration of phenolic and conjugated aromatic compounds, and activity of extracellular enzyme. In addition, result of product characterization using GCMS revealed compounds equivalent to 13,60%, 26,20% and 90,8% respectively for gasoline, kerosene and diesel components. Those confirmed that urea can be used as an alternative nitrogen source to support Trichoderma sp. in lignit biosolubilization producing petroleum compounds.

Pterygoplichthys pardalis bones that are thrown into the river is one source of pollutants in the Ciliwung River. P. pardalis bones have a high calcium content, they can be used as an alternative raw material for flour. The purpose of this study was to analyze the nutritional content of P. pardalis bone flour from the Ciliwung River. The research method used was a proximate analysis consisting of moisture, ash, fat, protein, and carbohydrates content analyses. Proximate analysis results showed that the P. pardalis bone plus head flour contained 3% moisture, 35% ash, 34% protein, 23% fat, and 5% carbohydrate. P. pardalis body bone flour contained 4% water, 37% ash, 37% protein, 19% fat, and 3% carbohydrate. Based on the proximate analysis results, P. pardalis bone flours did not met the national standard of SNI 2013 fish flour for quality I, II, and III. Until now, there has been no research that explain the nutritional content of bone flour of P. pardalis from Ciliwung River. This research provides information on the nutritional content of P. pardalis flour. Data obtained from the results of this study can be the basis for consideration in utilizing and processing P.pardalis from the Jakarta Ciliwung River.

Produksi Gas metana Batubara (GMB) dapat ditingkatkan dengan cara biologi, yaitu melalui teknik biostimulasi dan bioaugmentasi yang dapat dilakukan secara in situ atau ex situ. Penelitian ini memanfaatkan mikroba cairan rumen yang diambil dari limbah rumah potong hewan. Cairan rumen mengandung konsorsium mikroba yang terdiri dari bakteri, protozoa dan fungi yang potensial dapat mendegradasi batubara untuk menghasilkan gas metana. Mikroba rumen memiliki kemampuan mencerna lignin dari tanaman yang merupakan materi asal mula batubara. Penelitian ini dilakukan dengan variasi konsentrasi campuran cairan rumen, jenis batubara, air formasi, suhu, dan tekanan. Hasil penelitian menunjukkan bahwa mikroba cairan rumen memiliki kemampuan untuk memproduksi gas metana, Volume gas tertinggi didapatkan dari batubara peringkat subbituminous pada suhu 60oC, tekanan 400 psi dan salinitas 35.000 ppm, yaitu diperoleh gas metana sejumlah 256 cf/ton dengan lama inkubasi 75 hari. Sedangkan pada batubara lignit dengan kondisi tekanan dan temperatur ruang (ambient condition), menghasilkan gas metana sebanyak 73,39 cf/ton dalam waktu 95 hari inkubasi. Produksi gas metana akan terus mengalami peningkatan sejalan dengan lama inkubasi dan tersedianya substrat batubara. Mikroba cairan rumen telah terbukti memiliki kemampuan untuk mendegradasi batubara menjadi gas metana sehingga potensi implementasinya dapat ditingkatkan dari skala laboratorium ke skala lapangan bawah permukaan untuk sumur CBM non-produktif.Production of Coalbed Methane (CBM) can be improved biologically, through biostimulation and bioaugmentation techniques which can be done by in situ or ex situ. This study utilizes microbial of the rumen fluid taken from animal slaughterhouse waste. Rumen fluid contains a microbial consortium of bacteria, protozoa and fungi that can potential to ferformace degradation of coal to produce the methane gas. Rumen microbes have the ability to digest lignin from plants that are the material of the origin of coal. This research was conducted with the variation of concentration of rumen fluid mixtures, coal type, water formation, temperature, and pressure. The results showed that rumen microbial fluid had the capability to produce methane gas. The highest gas volume was obtained from subbituminous coal rank at 60C, 400 psi pressure and 35,000 ppm salinity, which produced methane gas volume of 256 cf / ton on 75 days incubation period. While from lignite coal of the ambient conditions was obtained methane gas volume as much as 73,39 cf / ton for 95 days of incubation time. The gas production will continue increasing in line with the incubation period and the availability of coal substrate. The rumen fluid microbes has been proven having capability to degradation of coal to producing methane gas so that potential implementation from laboratory scale to subsurface field scale for the non-productive CBM wells can be raised.
