Abstract

Rupat Strait is one of small strait in Malacca Strait which located in among coastal of TownDumai area with the Rupat Island in Riau Province. Position of Rupat Strait semi-closed withthe condition of semi-diurnal tide has potency to cause the happening of oil accumulation interritorial water which can generate the damage of ecosystem territorial waters. Strait Rupatown the variety of various type mangrove representing habitat of various fish type and protectthe coast from wave and aberration. Various transportation activity, processing and oildistribution in coastal area of Dumai cause the territorial water of Strait of Rupat gristle to oilcontamination. Lubuk Gaung is a very sensitive regional to oil contamination. Pulau Ketam is asensitive criteria, but region Pelintung is inclusive of middle criteria untill is not sensitivity.

Abstract

his study aims to identify and analyze the condition of land cover in the area of hydropowercathment Koto Panjang area based on Landsat image analysis in 2001 and 2008, knowing theeconomic activity undertaken by people who lived in the area of hydropower cathment KotoPanjang area and its influence on the preservation of the area cathment Hydroelectric KotoPanjang. The method used in this study is to survey, which collected data consists of primarydata and secondary data. Primary data were obtained from interviews and observations madeon society and the natural conditions in the village sample (Ranah Sungkai, Koto Tuo, Tabing)While secondary data obtained from the results of the study and documentation of variouspapres and official reports from various related agencies.Based on analysis of Landsat imagery in 2001 and in 2008, it is known that in the area ofhydropower cathment Koto Panjang area there are 12 land cover types, namely primary uplandforest, secondary upland forests, scrub / shrub, shrub / scrub wetlands, vegetation youngorderly, vegetation the old order, settlement, plantation, dry land farming, dry land farmingmixed with shrubs, open ground, and the water body itself. The forest area is an area thatexperienced the largest reduction of 15.55%. Meanwhile, scrub the area is an area thatexperienced the largest increase of 11.47%.Economic activities undertaken by the public within the area of hydropower cathment KotoPanjang area mostly gardening. Cultivated plantations dominated by rubber and oil palmplantations. Palm oil plantations started a trend by the public since the year 2004/2005 because t thinks the oil palm plantation is more profitable than rubber. While the rubber plant ingeneral they earn less attention to the rules of conservation of soil and water, where most of theterracing was not conducted on lands mostly ride a bicycle. In addition they earn rubbermonoculture is still, there is no innovation to be done heteroculture or agroforestry patterns thatare economically and ecologically more favorable course.

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

Development Policy, Regulation and clean water resources controls in Pekanbaru Town can beachieved by constructing appropriate permit and regulation. However, the current permit andregulation do not include several important aspects such as domestic waste pollution limit forexcrement waste in individual housing. On the other hand, poor coordination for protection ofclean water resources is giving housing developer a chance to build a house according to theyown standard, which is far from expectations. In fact, from 80 houses, that have already builtand owned, indicate that only 26 percent of the houses have located septic tank 10 meter awayfrom the house’s clean water resources. Nevertheless, 90 percent of the houses do not havewater resistant septic tanks and about 40 percent the septic tank never been empty. The otherproblem is that clean water quantity 48,75 percent of the house has this issue, followed by waterodor problem 74,4 percent and the last problem is the total house has breach legal limit for theamount of coliform in their water has reached 50 percent. It is recommended that Pekanbarugovernment have to improve their current Clean Water Resources policy by creating newstandard operational procedures (SOP), and increase the supervision of housing development,especially in real estate industry in Pekanbaru Area as well as the function and sectionimprovement of current duties. When the policy is improved with SOP and supported by theincreasing of supervision and coordination, Clean Water Resources pollution can be controlledand minimise.

Abstract

Research has been conducted to determine the distribution pattern of rubber waste in the sub-surface by application of geoelectric methods. The reading showed that the resistivitydistribution were zero (at z = 0) before registration of rubber waste. The minimum value ofresistivity were of 13.1 ohm.m, while the maximum of 112 ohm.m. Distribution pattern of rubberwaste in the subsurface revealed that the minimum value of resistivity were of 20.8 ohm.m, whilemaximum of 122 ohm.m. The resistivity distribution before rubber waste application was of at z= 33 cm that accounts for the minimum value of resistivity 31.5 ohm.m, while maximum 124ohm.m. Distribution pattern of the waste in the subsurface come up with minimum and maximumof resistivity distribution of at z = 33 cm the were 7.11 ohm.m,and 96.6 ohm.m, respectively.

Abstract

This research was conducted from April-March 2007 in the waters around the PelabuhanTanjung Buton, Riau Province. The aim of this research is to understand the variation of speciescomposition and abundance of epiphytic diatom presenting on the trunk and Pneumatophores ofavicennia sp which is related to water quality factor. Survey method was applied on thisresearch where data were obtained by direct observation in the field. The samples of epiphyticdiatom were analyzed in the Laboratory of Marine Maicrobiology. Water quality parameterswere measured in situ.Twenty Two genus of epiphytic diatom that were consisted of 37 species were found.32 specieswere present on the trunk and 30 species on the Pneumatophores. The abundance of epiphyticdiatom on the trunk ranged from 459 to 10107 ind/cm2 while on the Pneumatophores is from 459 to 9648 ind/cm2. Beside that, water quality parameters were in the sufficient range formarine epilithyc diatom.
