Item Different Activated Carbon As Adsorbent In Reducing Total Hardness: The Impact To Oxygen Consumption Rate Of Nile Tilapia Oreochromis niloticus(2016-03-22) D. Sanjayasari; N. AndriyaniThe study was to determine the effectiveness of two different activated carbons in reducing total hardnessas one of principal component in water quality and also their affect to oxygen consumption rate in Nile Tilapia. The present of Ca and Mg in water has become essential as micronutrient for aquaculture. Unfortunately it became a threat when the level was above average.Aactivated carbon from agriculture waste became one of solution to solve high hardness in the water. The treatments were P0 (control with no carbon active), P1 (coconut shell) and P2 (rice husk). The research was used Completely Randomized Design (CRD) with five replications. The result showed water quality parameters still in range with pH 6-8 and temperature of 280C. Meanwhile, the best result of total hardness reduction was expressed significantly (P<0,01) 78,9% by P2 rise husk activated carbon. The same result was expressed by P2 treatments (P<0,01) in oxygen consumption rate of Nile Tilapia. Based on the research concluded that rise husk activated carbon gave the best performance in reducing water hardness and increasing oxygen consumption efficiency of Nile Tilapia.Item The Effect of Activated Carbon on Biodegradation of Soil and Ground Water Contaminated with Petroleum(2016-03-30) Afriani, Susi; Effendi, Agus JatnikaThe soil and ground water contaminated with petroleum research increases in many observation. This will become important since the soil and ground water contaminated petroleum was hazardous waste and toxic for human life, aquatic biota and not environmental friendly. Biological Remediation process as called Bioremediation is one of popular treatment for Total Petroleum Hydrocarbon (TPH) removal , which is in slurry phase system (contaminated soil contacted with make up water). In this research was hold on slurry phase system. The purpose of this research was to evaluate the biodegradation of hydrocarbon degradating bacteria in the presence of activated carbon hold on slurry phase system. In this research Total petroleum hydrocarbon (TPH) removal will become measurement parameter since activated carbon and bacteria simultaneously in 250 mL batch reactor. From this research was found that with 10 gr activated carbon and bacteria revealed that there was a significant TPH reduction in the level 11,12 % to 0,94 % during 18 hour observation. The percentage reduction was found 91,55% for reactor with activated carbon contacted bacteria and 85,5 % for reactor with bacteria only. The pattern of bacterial growth in activated carbon added to the reactor which is also better than the reactor without the addition of activated carbon.
