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.

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.
