Abstract

Implemetasi underdeveloped research for large-scale production of energy self-sufficient villages and confined in a laboratory scale. The presence of mangrove forests alongthe palm beach pesIsir Indonesia is a potential independent village granaries Energy (DME)to produce local non-fossil energy resources, namely bioethanol as an energy mix throughthe substitution of fossil fuels in order to add and save energy nationwide. Exploration ofgreen energy production process Tempatan with scale appropriate technology is essential toknow the characteristics and potential of bioethanol and fuel substitution products will beproduced. The purpose of this study was to determine the characteristics of bioethanol frompalm sap processing to scale the application of appropriate technology and the potentialvalue of bioethanol FGE levels that would result in a 1 ha of mangrove forests nypa.Research using experimental and observational methodologies. Palm sap is used as thesubject of this study is the result of tapping mangrove palm bunches done processingfermentation, distillation and dehydration. Data collected includes data 1). Characteristic,among others: fermentation, Kadar Alcohol Distillation and Dehydration results TTG Tools,Redemen Bioethanol, Nipah Bioethanol Quality Testing Specifications for Substitute GradeFuel, Bioethanol Blending Testing FGE The substitution process to Fossil Fuels andCounting Bioethanol substitution needs to Biopremium octane FGE 92-95. And data 2). Thepotential value of Bioethanol and Biopremium Nipah. Furthermore, the data obtained andanalyzed, if there is a significant difference followed by Duncan test at 5% significance level.The results showed the characteristics of bioethanol from palm sap processing to scale the application of appropriate technology for fermentation derived average fermentation time isbetween 75.3 to 78 hours, or about 3 days, the average alcohol content of 81.3% obtained bydistillation and 93% as much as 2 times the process and result of dehydration reached 100%for the first time, redemen bioethanol by 8.1%, or a ratio of 12 Litre fermenting juice: 1 Literbioethanol FGE, quality testing specifications nypa fuel grade ethanol to substitute ethanolcontent nypa production equipment amounted to 99.56% TTG already qualified ISOstandards, testing FGE in the bioethanol blending into fossil fuel substitution showed ahomogeneous mixing and calculating FGE bioethanol substitution needs to biopremium 92octane produces a ratio of 1% use 95-octane bioethanol to produce ratio of 2% use ofbioethanol. Furthermore, the potential for the production of bioethanol from palm mangroveforest area of 1 ha with the highest value of 13179.43 liters / ha / year and the lowest value of2744.17 liters / ha / year. Biopremium production potential for the substitution of 10%obtained the highest value and the lowest value of 137,298.50 658,971,50 Liter.

Abstract

The experiment and observation of embriogenesis of Silais fish (Criptopteris limpok) wereconducted in Laboratory of Agriculture Faculty, Islamic University of Riau in December 2009.The aim of this study was to investigate the effect of temperature on a number of newly hatchedC. limpok and to describe the embriogenesis. Survival rate of larvae was 5 times higher intreatment (25oC) compared with control (29oC), i.e. 5% in treatment and 1% in control. Thenumber of larvae survival rate was low, but this condition was predicted causeb by low qualityof gamet. Embriogenesis development of eggs need 24 hours of length period of time to hatch,and they have a yolksac during 4 days.

Abstract

This research was conducted on March to August 2012, at Public Health Center of SiakHulu II Kampar regency. This study generally aims to evaluate the program of theenvironmental health at Public health center of Siak Hulu II Kampar regency in 2012,while the specific objectives are to evaluate the program landfills and waste andevaluate vector control programs in Public health center of Siak Hulu II Kamparregency. The method used in this research is a qualitative method. Analysis of the datausing content analysis to obtain in-depth information from informants about landfillsand waste and vector control to be made by noting the matrix and analysis manually.The results of program activities of landfills and waste at Public Health Center wasnot performing well and was not achieving the target set, where the environmentalhealth officers only surveyed garbage and waste in communities residential, whilemonitoring of garbage and waste in another place there has never been carried outsupervision and follow-up. In monitoring garbage and waste, due to limitedenvironmental health officer and far distance of coverage areas, health officerssupervise in line with the counting of numbers of the free larva, while the results of theVector Control Program for vector causing dengue fever can be accomplished inaccordance with procedures established by the Department of Health, but there areobstacles to doing fogging because Public health center firstly have to collect case ofEpidemiology investigation (PE) for a month and then report to the regency HealthOffice to conduct fogging while for vector types causes other diseases that are notcontrol ever only if there is a problem in the society so Public community health centerwill cooperate with existing cross sector of health center working area and doingoutreach to the community

Abstract

Observation was conducted to analyze the different density of Diadema setosum urchin in theseveral condition of coral reef in Mapur Island of Riau Archipelago Province, from 16 until31 July 2010. The result showed that density of urchin increase by decreasing coral cover.Density of sea urchins Diadema setosum were found 8.8 ind/m2 in the highest percentagecoral cover, i.e. 84.62%, and followed by 22.46 ind/m2 urchin in 59.74 % coral cover, and32.06 ind/m2 urchin in the condition of coral cover 35.15%. The different results amongthree research station may be coused by available of D. setosum.

Abstract

Observation of oil concentration was conducted to know pattern of oil distribution in Rupat Strait in front of Dumai City, Riau. Samples were collected on 19 sampling side on Rupat Strait in June 2007, and the samples transported to Chemistry Laboratoty, FMJPA, Riau University before data were analyzed by using software surfer. Highest concent ration of oil was detected around harbor of Duinai City and distribu ted to both northern and southern from around the Harbor. Concentration pattern of oil distribution decreased toward all directions from a round harbor, and may be controlled by tidal current which cause oil distribution occurred horizontally with the coast of Dumai City side was longer thami vertical distribution from Dumai side to Rupat Island.

Abstract

ABSTRACTDinoflagellates are group of phytoplankton that is besides plankton are also benthic. Its abundance in the waters may cause red tide phenomenon. Abundance of Benthic Dinoflagellates in waters influenced by several environtmental factors. The method used is an experimental method. Sampling using artificial substrates (gauze). The results showed on the Muara Padang station has the highest concentration of nitrate and phosphate are 0,195 and 0,028 mg/l with the lowest value of the abundance of benthic Dinoflagellates 400,4 cells/100cm2 and the lowest concentration of nitrate and phosphate is located on the Teluk Bungus station are 0,033 and0,003 mg/l with the highest value of the abundance of benthic Dinoflagellates 660,4 cells/100cm2.
