Abstract

The experiment was conducted to in order know the effect of effective microorganisms(EM4) on the tofu waste water in the Chemical laboratory FMIPA Riau University Pekanbaruon 18 March - 08 April 2010. Samples were taken from outlet of tofu industry Sido RukunStreet Kecamatan Payung Sekaki. The treatment was using EM4 with concentration of 1:20(Treatment A), the second treatment was using concentration of EM4 1:10 (Treatment B) andC as control. The results of the experimental showed that Treatment A was more effectivethan Treatment B and Control in decreasing BOD and COD for 13 days experiment.

Abstract

The study was aimed to identify and analyze social environmental aspects of beef meatballmerchants’s behaviour that is potencial to cause the case of borax content on meatball in Pekanbaru. Results of the study were expected to be a preliminary study about beef meatballmerchants’s profil in Pekanbaru that could be used as the guide of next studies in detail.The study was carried out during January 2010 in Pekanbaru. There were 128 beef meatballmerchants used as respondents taken by simple random and purposive throughout the city. Identification of social environmental aspects was done by using questionaire and researcher’sguidance to avoid mis-perception. It was a survey method to identify some aspects such as 1)age; 2) education; 3) selling experience; 4) duration of daily selling; 5) daily omset; 6)government; and 7) preference of beef meatball texture based on merchants. Data analysis wasdone by tabulation and descriptively showed by mean and percentage. Results of the study showed that most of beef meatball merchants in Pekanbaru Municipalitywere 34,8 years old on the average (productive age), have low formal education and 9 yearsselling experience on the average. They got Rp. 998.696,- daily omset on the average during 8hours of daily open. They also said that they didn’t get elucidation from the goverment and theirpreference of beef meatball texture were rubbery. The social environmental aspects werepotencial to emerge the behaviour of adding borax into beef meatball processing.

Abstract

His research aim to detect the extent to which the relationship of these variables on a factorassociated with the variables on one or more other factors based on correlation coefficients. Thehypothesis proposed in this study were: (1) awareness of the environment is influenced by thevariable knowledge, attitudes, behavior and participation; (2) willingness to pay is influencedby the variable knowledge, attitudes, behaviors, and participation through environmentalawareness, and (3) willingness to pay is influenced by the ability to pay. Based on a hypothesistest results are not entirely acceptable, because the path coefficient based on testing a sub-structure, only the knowledge variable path coefficient (X1), behavior (X3) and participation (X4)on environmental awareness (Y) which is statistically meaningful and acceptable, whereas thepath coefficient attitude variable (X2) was not statistically significant and rejected. Secondhypothesis test results are not entirely acceptable, because the path coefficient based on testing,only the knowledge variable path coefficient (X1), behavior (X3) and participation (X4) againstthe capability to pay (Z) through environmental awareness (Y) and statistically significant andaccepted, whereas the path coefficient attitude variable (X2) was not statistically significant andrejected. While the relationship between the ability of the respondent's willingness to pay forriver water quality improvement program shows good relationship. This may illustrate that thehigher the ability to pay the respondents will follow the higher the willingness to pay.

Abstract

A study on fish biodiversity of Kampar River has been conducted. The study aimed at evaluatingthe existence of inhabiting fish species in the river and tributaries, in response to frequentdisturbance of water quality and quantity regime, due to anthropogenic factors. It revealed thatfish community found comprises of 9 ordo, 23 family, 40 genus, and of 58 species. Fish of familyCyprinidae, Bagridiae and Siluridae, were dominant in all sampling area with 25, 4 and 4species, respectively.

Abstract

Malaria is a disease caused by Plasmodium parasites. Year 2007 people infected with malaria District Sungai Mandau 57.37 per 1000 population. This study aims to determine ecological factors that affect the habitat of the Anopheles mosquito larvae in the village of Muara Kelantan District Sungai Mandau, Siak Regency in 2009. Depth of water, water flow, mud bottom, thecolor of brown waters, and temperature, salinity, pH water,and humidity on the waters in the village of Muara Kelantan suited for the life of the larvae of Anopheles spp. This is supported bythe density of mosquito larvae of Anopheles spp calm in the gutter, the gutter flow and swampland in succession 0,006 ind/ml, 0,078 ind/ml, and 0,004 ind/ml respectively.

Abstract

The purposes of this research were to get the best inoculum concentration and also to identifythe ability of mixed culture of hydrocarbonoclastic bacteria in oil waste degradation. The isolatswere used are Acinetobacter baumannii, Alcaligenes eutrophus, Bacillus sp1., Methylococcuscapsulatus, Bacillus sp2., Morococcus sp., Pseudomonas diminuta, Xanthomonas albilineans,Bacillus cereus and Flavobacterium branchiophiia. Variation of inoculum concentrations were10%, 15%, and 20% (v/v). Observed parameters in optimization were Total Plate Count (TPC)the culture every 24 hour, Total Petroleum Hydrocarbon (TPH) and Chemical Oxygen Demand(COD) examined at the end of the bioremediation period. Best optimization result then analyzedwith GC/MS. Optimization result indicated the best inoculum concentration was 10% with TPHdegradation 61,79% and COD slope 61,75%. It is assumed that the low value of TPHdegradation and COD slope at 15% and 20% inoculum concentration were caused bycompetition inside the bacterial population at that high inoculum concentration. Thecompetition result in low growth and degradation. The chromatogram indicated thathydrocarbon compound from nC9 – nC32 have been degraded by 9,887% – 88,056%. Theconclusions of this research is the best result of bioremediation was obtained concentrationinoculum at 10% mixed culture.
