The anaerobic ammonium oxidation (anammox) as a new biological approach for nitrogen removal has been considered to be more cost-effective compared with the combination of nitrification and denitrification process. However, the anammox bioreactors are mostly explored at high temperature (>300C) in which temperature controlling system is fully required. This research was intended to develop and to apply anammox process for high nitrogen concentration removal at ambient temperature used for treating wastewater in tropical countries. An up-flow biofilm column reactor, which the upper part constructed with a porous polyester non-woven fabric material as a carrier to attach the anammox bacteria was operated without heating system. A maximum nitrogen removal rate (NRR) of 1.05 kg-N m3 d-1 was reached in the operation days of 178 with a Total Nitrogen (TN) removal efficiency of 74%. This showed the biofilm column anammox reactor was successfully applied to moderate high nitrogen removal from synthetic wastewater at moderately low temperature. Keywords: Anammox, biofilm column reactor, ambient temperature, nitrogen removal

Biogas is an environmentally friendly renewable energy source. Biogas can be used using Palm Oil Mill Effluents (POME). However, the % yield of biogas productivity is still not optimum due to the low conversion. The biogas productivity can be optimized by adding methanogen bacteria which increase the methane production through the anaerobic fermentation process. This study aims to utilize cow manures as the source of methanogen bacteria in methane production from POME. Furthermore, this study specifically aims to obtain the optimum productivity condition of biogas production by the composition ratio of POME and cow manures to the amount of fermentation time at 35oC and 50oC for mesophilic and thermophilic bacteria, respectively. The ratio of POME and cow mature were A1 (100:0), A2 (80:20), A3 (70:30), A4 (60:40), and A5 (0:100). The highest yield of biogas production was A2 ratio using the thermophilic condition which showed 51.33% mol with the total solid decline of 73.43%, COD removal of 77.01%, and BOD removal of 70.02%.

Abstract: Candida tropicalis isolated from Tuak is a potentially useful microorganism for the ethanol production from lignocellulosic biomass and it can be alterbative agent replacing Saccharomyces cerevisae for fermentation process. Although C.tropicalis could not convert all carbohydrates content of lignocellulosic into bioethanol, however it is able to grow on medium in the presence of either xylose or arabinose as carbon source. Our result showed that fermentation of 10 % (w/v) cellulosic as sole carbon source produced 2.88% (v/v) ethanol by C.tropicalis. This ethanol production was lower than usage of 10% (w/v) dextrose as sole carbon source medium which producing 5.51% (v/v) ethanol. Based upon our expreiment indicated that C.tropicalis is able to conduct two main process in converting of cellulosic material- to ethanol which is hydrolysis the degradation of cellulose into glucose, and fermentation the process the conversion glucose into bioethanol.Keywords : Candida tropicalis, bioethanol, fermentation, cellulosic Abstrak (Indonesian): Candida tropicalis yang diisiolasi dari Tuak adalah agen yang berpotensi dalam produksi etanol dari biomasa lignoselulosa dan dapat dijadikan agen alternatif menggantikan Saccharomyces cerevisiae pada proses fernentasi. Walaupun C.tropicalis tidak dapat mengkonversi semua kandungan karbohidrat lignoselulosamenjadi etanol, akan tetapi C.tropicalis mampu tumbuh pada media dengan xilosa atau arabinosa sebagaisumber karbon. Hasil kami menunjukkan bahwa dengan mengguankan C.tropicalis fermentasi 10% (w/v) selulosa sebagai satu-satunya sumber karbon menghasilkan 2,88% (v/v) etanol, Produksi etanol ini lebih rendah jika menggunakan 10% (w/v) dekstrosa sebagai satu satunya sumber karbon yang menghasilkan 5,51% (v/v) etanol. Berdasarkan percobaan menunjukkan bahwa C.tropicalis mampu melakukan dua proses utama dalam mengkonversi material selulosa menjadi etanol yaitu hidrolisis degradasi selulosa menjadi glukosa, dan fermentasi proses konversi glukosa menjadi bioetanol.Kata Kunci: Candida tropicalis, bioetanol, fermentasi, celulosik

The construction of power plants is very necessary to anticipate the crisis of electricity resources and always increases every year. Tanjung Enim city has Steam Power Plant (SPP), one of them is Banko SPP which has 3 x 10 MW capacity. It was built to meet the demand for society electrical energy. The existence of this SPP construction can cause environmental degradation such as a decrease in water quality that does not meet environmental quality standards. The decline in environmental quality can also have a direct impact on the community around the Tanjung Enim SPP location. This is due to the existence of SPP operational activities that can produce liquid waste such as boiler blowdown, airheater blowdown, cooling system and domestic waste waterfrom the manufacturing process. This research study aims to analyze water quality around Banko SPP based on the physical and chemical parameters by testing in the laboratory. The approach employed in this study was an experimental method that included laboratory sample and testing. The water quality pollution index (PI) which refers to the Ministerial Decree No. 115/2003 (Environmental Decree) was used to analyze the result of laboratory testing. The water quality samples examined in this study were wastewater treatment plant (WWTP) outlet, river water, and groundwater nearest to the SPP's location. The phenol and chlorine parameters exceeded the quality requirements referred to in the South Sumatra Governor Regulation No. 16 of 2005, according to the findings of laboratory testing of river water samples. The mercury (Hg) parameter in the WWTP outlet samples surpassed the South Sumatra Governor Regulation No. 16 of 2005 quality criteria. Meanwhile, the manganese (Mn) parameter in groundwater samples surpasses the quality requirement established by the Government of South Sumatra Regulation No. 82/ 2001 as Class I clean water quality criteria. The water quality pollution index (PI) method achieves a score of 1.52 with the category of Lightly Polluted. Based on these findings, it can be concluded that the influence of SPP Banko's operations on water contamination is minor.

The reclaimed lowlands of Indonesia with the respective of 256 hectares of secondary block consist of 16 hectares of tertiary blocks, were used for rice plant production. Paddy was planted during the rainy season of November to February. It was followed by water melon plant in March to May. Then corn was growed in the dry season of June to September finally. Fluctuations of water table in the farm is very crucial in determining the cropping calender. Water management with free drainage approach is influenced by tidal water movement into the tertiary canals bordering the farmers fields. A constant water retention -10 cm below the canal bank has increased the water table in the farm from -10 cm to +20 cm. Water retention (controlled drainage) mode was applied by the farmers especially during the rice growing period. The release of water in the canal to a depth of -50 cm below the canal bank had lowered the water table level to -20 cm. During almost 200 days of experimental work, soil and water samples were taken by 11 times. The content of NO3-, NH4+and pH of the soil sample and be analyzed in relation to the water table fluctuation. Groundwater level does not show the effect on nitrate release on the urea application stocked. however, on the high ground water level it appears to be more in control of ammonium release compared to the ground water level of -20 cm.
