Abstract

The conventional rice cultivation of Traditional Flooding (TF) seems to be wasting the water and potentially polluting the soil and water due to improper chemical fertilizers and pesticides management (Nguyen et al., 2007). System of Rice Intensification (SRI) is one of the innovative rice cultivations with the principle of single seed replantation and intermitten irrigation (IWMI, 2007). The experiment was conducted to analyze the macro nutrients, total microbes, and the rice production by combinations of nutrient and pest management in TF and SRI system. This study applied a nested experimental design with two factors. The first factor was the cultivation system that consisted of two levels (TF and SRI), and the second factor was nutrient and pest management consisted of three combination levels (synthetic nutrient and pest management/P1, organic-synthetic nutrient and organic pest management/P2, as well as organic nutrient and pest management/P3). These combinations were nested to TF and SRI. Data were analyzed by ANOVA. It is found that P1 showed the highest growth and production in SRI and TF. The numbers of the height, tillers, total grains and the weight of seed per pot in SRI respectively are 87.33 cm, 22.17 tillers, 1179.50 grains, and 32.17 g, meanwhile in TF respectively are 78.75 cm, 17.50 tillers, 1063.33 grains and 29.00 g. P3 shows the highest content of macro nutrients and total microbes in SRI and TF, respectively the contents of C, N, P and K of P3 in SRI are 6.82 % (very high), 0.31 % (moderate), 155.69 ppm (very high), and 1804.85 ppm (very high), meanwhile in TF respectively are 6.52 % (very high), 0.25 % (moderate), 52.60 ppm (very high), and 530.79 ppm (very high). The total microbe contents of P3 in SRI and TF respectively are 2.7 x 108 CFU/g and 3.7 x 108 CFU/g. It is concluded that both in TF and SRI system (1) P1 shows the highest growth and production and (2) P3 shows the highest content of macro nutrients and total microbes. Furthermore, it is suggested that in the future the rice cultivation system should be done in a wider scale and multiple planting seasons in order to be able to precisely measure the significant difference of the rice cultivation system towards the rice growth and production.

Pollution parameters that have exc.eeded the quality standard, are: BOD, COD, Total Phosphate, Total Coliform, and Faecal Coliform. It requires to concerned because Sungi River as the point area for drinking water in Tabanan (data of Environmental Board of Bali Province). Purpose of research is to determine the characteristic of pollution source which will be impact to the changing of water quality in physical, chemical, and biological in middle and down stream area, detern1ine the pollution index in up stream, middle. and dow stream area of Sungi River. Water parameters that will observe are: temperature, pH, turbidity, TDS, TSS, DHL, DO, BOD, COD, Total Phosphate, Total Coliform and Faecal Coliform. The measurement result will compare with the best of water quality, based on the Regulation of Bali Governor Number 8 Year 2007, because of it utilization as drinking water. Result of research shown that the activity in Sungi River dominated by agriculture activity, settlement, animal husbandry, and industry that located in dov.n stream area. The waste that result from the above activities caused the degradation of water quality that shown by the increasing of water parameter indicators, such as: BOD, COD, Total Phosphate, and Faecal Coliform Bacteria. In the middle will increasing and down stream area will get degradation. This condition is inversely proportional to the content of DO as impact of contaminants accumulation, such as: organic waste in middle are, because the water movement is more calm with average water flow is 0,14 m/second compared with the up and down stream area with average water flow are 0,15 m/second and 0,35 m/second. Characteristic of pollution source which effect the water quality at Sungi River in area I caused by llie activities of agriculture, animal husbandry, settlement, and industry, for area II caused by the activities of agriculture, animal husbandry, settlement, and villa. The quality staLus of Sungi Rlver in up stream area still result a good quality water but in the middle and down stream area are get lightly pollution. Water quality parameter which exceeded a good water quality in Sw1gi Rive,· is Total Phosphate with average value is 0,44 mg/I in the middle area, 0,40 mg/l in down stream area and Faecal Coliform with average value is 166/100 ml in the middle area and 152/100 ml in the down stream area.

Abstract

Development of the population and the increasing demand for health services has led to the increase in the number of hospitals, both government hospital and privet hospitals. The presence of ammonia as a result of protein decomposition can be toxic in the waters. The application of anoxic-oxic biofilter system is an attempt to be able to reduce ammonia levels in hospital wastewater. In the process of anoxic-oxic biofilter, contact occurs between the gravel media and microorganism to form biofilms which can accelerate the degradation of organic matter and the nitrification process. This study aims to obtain the best activated sludge source in reducing ammonia levels of wastewater applied to the anoxic-oxic biofilter system applied. This research was contucted in two stages in which the first stage of active mud nursery was carried out from three sources, namely WWTP Wangaya Hospital Denpasar, WWTP of PTN Hospital Udayana University and WWTP of Bangli Hospital for six days. At this stage a Mixed Liquor Volatile Suspended Solid (MLVSS) value is measured which shows the growth rate of biomass in activated sludge. The second stage is applivation of avtivated sludge and control to the anoxic-oxic biofilter system to reduce ammonia levels in hospital wastewater for five days of processing. This study use a randomized block design with four treatments and three replication. The results showed that the best activated sludge was obtained through nursery from WWTP of Wangaya Denpasar Hospital which was shown by the highest biomass growth (MLVSS Value) of 2433.3 mg/L and the highest reduction in ammonia reached a final level of 0.53 mg/L. The levels of effectiveness of the process of decreasing ammonia levels by 94.70% and has been able to pass the specified quality standard effectiveness percentage (90%) for five days of processing. The value of this effectiveness is the highest compared to the controls and other activated sludge treatment.
