Abstract

The utilization of non-timber forest products of mangrove palm (Nypa fruticans Wurmb) ofsap produced through the process of tapping,  is still made   by the traditional way with theamount of sap production is still small or limited for consumption purposes. Sap whichcontains sugar has a potency to be fermented  into ethanol which is a source of greenenergy. The problem is the amount of available sap as raw material obtained by traditionaltapping is still limited, therefore, more efforts to increase productivity are needed. Thepurpose of this study was to explore several methods of tapping palm from traditional waytowards  non-conventional technologies. This study used an experimental method examiningseveral factors including 1) Duration of pre-tap (10 days, 20 days, 30 days) 2). Pre-tappingstimulation (without and with stimulation) 3) Type of container (non-vacuum container(traditional), 1.5 L small vacuum container, 2L medium vacuum container  and 20L largevacuum containers). 4) The level of luxuriance palm leaf midrib (not dense 0-2 midrib, lessdense 3-4 midrib and dense > 4 midrib). Observed variables are sap volumes include volumesof palm sap/stem, sugar, tapping duration/stem. The result obtained from tapping processon mangrove forest in Lubuk Muda Village, Siak Kecil District, Bengkalis Regency RiauProvince showed that optimal productivity were obtained on 1). Pre-tapping stimulationat 30 days. 2) Treatment with pre-tapping stimulation. 3) Harvesting on the medium vacuumcontainer and 4) found in dense leaf midrib.

Abstract

Research on the analysis of the reduction of the potential of methane gas (CH4) in the processing of palm oil mill effluent with the method of processing through Biodigester and Conventional ponds. Palm oil mill waste management system PT. The Indo Palm Fertile Core which reduces CH4 by splitting the effluent out of the inlet is divided into 2 lines, each pathway of the system aims to reduce methane gas (CH4) that comes from the degradation of organic matter present in the liquid waste. Sample analysis was taken from 6 palm oil mill waste processing ponds owned by PT. Inti Indosawit Subur Pelalawan. In this study the authors calculated repetition of sampling conducted using the Slovin technique. The measured parameters of wastewater are Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), pH and temperature in each pond that affects the formation of methane gas and carbon dioxide. Analysis of methane gas is determined in 1 way namely theoretically using equations and using the Biogas 5,000 Gas Analyzer tool. Calculation of methane gas potential (CH4) is carried out to find out how much the potential of methane gas (CH4) in each WWTP pond. From the calculation of the potential emissions of methane gas (CH4) it will be known how much reduction in methane gas (CH4) in the treatment of liquid waste in PKS PT. Inti Indosawit Subur Pelalawan Regency. Results of COD anasis and methane gas potential in biodigesters The average value of COD loading on Biodigester per day in September at the time of sampling was 24,884 kg / day. Potential emissions of methane captured in the Biodigester is 7,838.46 Nm3 / Day. The percentage of potential methane emissions in the Biodigester per day is 31.5%. Whereas the highest methane gas pool was found in pond 3, which is 6.4 Nm3 / day, which was calculated theoretically with a percentage of methane gas emissions of 0.011%. However, if measured using a tool, the percentage of potential methane gas in a 3 COD pool of 58,112 mg / L is 0% at a temperature of 35 ° C and a pH of 8.38. The highest methane gas emissions occur in pond 3 during the daytime with a value of 6.4 Nm3 / Day on the first day, 6.95 Nm3 / Day on the second day, 6.41 Nm3 / Day on the third day and 6.67 Nm3 / Day on the fourth day, the potential emissions of the biodigester have been calculated by the company. The potential of methane emissions captured in Biodigester is 7,838.46 Nm3 / Day with the percentage of potential methane emissions in Biodigester an average of 31.5% per day. The highest value of methane gas emissions during the 4 days of the study was 6.95 Nm3 / day on the second day taken at noon with a pool temperature of 35 ͦ C.

Abstract

The research was conducted on May – June 2007 in side of Siak River at Kecamatan Rumbai Pesisir, Pekanbaru. The purposes of research is know that one of the impacts of pollution on Siak River is diseases carrying water had increased (diarrhea and skin diseases). Therefore, itneeded a research concern on the advantage effects of river waters toward diarrhea and skindiseases of community side Siak River (case on Kecamatan Rumbai Pesisir, Pekanbaru). Thehypothesis was that pollution on Siak River caused high prevalence of case on diarrhea and skindiseases, oppositely, the people had not used waters from Siak River had case by lowprevalence. The research design was conducted by cross sectional method where measurementand observation was conducted at the same time (once periodic) and sampling purposively.Then, data analyses got by chi square (X2) to determinate a correlation and the strength wasmeasured by odds ratio (OR) value. The result of analyses was show that toilet activities(bathed, washed and water closet) had proved that people used river water would had higherrisk affected by skin diseases than people had not used it. Bath activities was OR = 1,659 thatmeans people had take bath in Siak River would higher affected by skin diseases 1,659 timeshigher than people had not bath in river. Washed cloth activities was OR= 2.032; washed dishand kitchen tools OR = 1,737 and used water closet OR = 2,217. There was not correlationbetween the toilet activities (bath, wash and water closet) with diarrhea disease; significantly, itcaused diarrhea disease usually affected by drinking water that disturbance of digestive system.But, in this research might not proved correlation between the using drinking water withdiarrhea disease. It might caused by few sample or although people didn’t used the water river as drinking water, directly, but still affected by diarrhea. And people percentage affected bydiarrhea disease was great in 25 percent.

Abstract

This research aimed at analyzing the relationship among people’s behavior with dengue fever which is 3M plus, environment condition, the existence of mosquito’s larvae, social-economics factor, and the dominant factor toward dengue fever in Pelalawan. The research was quantitative with case control study approach. The population was total of dengue fever patient in the working area of Pelalawan Berseri community health center. With the total were 31 cases and 31 controls. The measuring tool was Questionnaire which already done for validity and reliability by the former researcher. Also the medical devices to measure humidity, temperature, light intensity. The data were analyzed by using statistical test of chi square and logistic regression. The result showed that 3M plus variable is affecting the dengue fever (p value=0,001), The environment which is affecting it was humidity (p value=0,000), temperature (p value=0,032), light intencity (p value=0,000), and the existence of mosquito’s larvae (p value=0,000). Based on the comparison of the population numbers and dengue fever, it showed that there is a tendency of the increasing of dengue fever on the growth people’s population. The social impact that happen because of dengue fever are the change of family role, psychology disruption, worry, the change of social role, even the death of family member. The economic factor was the direct charge of health service which reaching rp.5.000.000 not including the blood transfusion. While, the family should spend the money for buying things outside the medical cost, it is about Rp 500.000 up to Rp 1.000.000  for foods, transportation, and the others. Another factor was the indirectly charge, such as the decreasing of family income because productive workday missing, because of sick, or need to take care for the family. The most dominant factor with dengue fever was the mosquito’s larvae with OR 10,668. Based on the result of the research, it should be done with the fixing of house components, such as the ventilation and the windows. the The effort about environment health can be done by the counseling from health departments, supported by the community health centers, about the importance of 3M plus program. And also the activation of jumantik members in all of the community health centers.

Abstract

ABSTRACT Oil pollution in Bengkalis waters usually comes from land, marine transportation, defection port activities and oil industry. Oil pollution can be trapped in sediment because it can not be dissolved and difficult to degrade, one way to overcome pollution is by bioremediation. The purpose of this research was to isolate bacteria from sediment Sungai Pakning waters, to examine the ability of isolates in degrading crude oil and to identify the bacterial isolates genetically based on sequence 16S rRNA. The research was conducted from March to May 2018. Bacterial isolation was conducted in Laboratory of Marine Microbiology and the oil degradation analysis was conducted in Laboratory of Chemical Oceanography, Faculty of Fishery and Marine Science, University of Riau. This research used survey and experiment method, survey method to measuring of water quality, removal of sample and isolated of bacteria, experiment method to examine the ability of isolates in degrading crude oil. The result showed that eight isolates (7D15, 7D35, 7D23, 14D15, 14D34, 21D13, 21D23, 21D35) were able to degrade crude oil at 1-3% concentrations. The highest degradation at 1% concentration was indicated by 21D35 isolate, at 2%  concentration is indicated by  21D13 isolate, and at 3% concentration is indicated by 7D23 isolate.
