Abstract

Clean water fullfilment become a common problem and yet to be solved  especially for isolated countryside area. Clean water can be defined as daily needs water and its quality should fullfil the requirement of healthy water based on laws and can be drinked when it is cooked.  High demand of clean water for peat area community  made this research to be important. The utilization of simple water treatment system is expected to solve the problem of clean water for the comunity. The purpose of this research is to determine effective thickness comparison of the surface filter. Treatment method used in this research is biosand filter with media of gravel and quartz sand. Water quality parameter tested are pH, color, solution degree, and organic contain (KmnO4). Statistical analysis used in this research is One Ways Varian Analysis (Anova). The result of the research shows that biosand filter able to improve the quality of peat. Thickness Comparison of the Surface Filter at the Biosand Filter have a significant influence on the value of the solution degree. Biosand filter can generate maximum efficiency in raising pH value of 33,90%, lowering peat water solution level of 82,56 %, lowering peat water colour value of 87 ,98 % and also lowering organic content of 83,88 %. Keywords : peat water, biosand filter, sand, gravel

Abstract

This study is to evaluate the mechanical properties namely compressive strength and splitting tensile strength of concrete using clamshell powder as a partial cement substitute. The clamshell powder was made from grinding Anadara grandis shells that were burnt at furnace brick and filtered using no #200 sieve. An initial investigation was carried out to make concrete specimens with partial replacement of shells powder using 2%, 4%, 6% and 8% of the weight of cement. The results of the initial study showed that the optimum clamshell powder proportion to get a high compressive strength was 4%. The specimens for compressive strength and splitting tensile strength were manufactured using 4% clamshell powder as a partial cement substitution. The specimens were tested atthe age of 7, 28, and 91 days. The results showed that the compressive strength of concrete using clamshell powder has lower strength than normal concrete for all age of specimens. On the other hand, the splitting tensile strength of concreteusing clamshell powder was higher than normal concrete.Keyword: clamshell powder, compressive strength, tensile strength, OPC

Abstract

The use of Palm Oil Fuel Ash (POFA) as a pozzolanic component in concrete continues in the future due to increase amount of POFA as by-product from industries annually. POFA is used as partial cement replacement in concrete and has significant impact on concrete’s performance. In this research, high volume POFA concrete with POFA replacement of 45%, 55% and 65% by cement mass were studied. POFA was obtained from local quarry in Riau Province. OPC concrete was used as control mix. Some properties namely workability, setting time, compressive strength, shrinkage and porosity were investigated. Results show that workability and compressive strength decreases as the POFA replacement increases in concrete. Porosity, shrinkage and setting time increases with an increase of POFA in concrete. It can be concluded high volume POFA using local material cannot improve the concrete performance significantly. Keywords: compressive strength, performance of concrete, POFA, porosity, pozzolans, shrinkage, setting times, workability

Abstract

Peatlands could contains water 20 times than it weight. Peat water is brownish red because it cointans high organic substances, therefore peat water should be treating before it can be used as clean water. Adsorption with activated carbon is potential as a method for remove color and organic substances on peat water. This research aims to investigate the characteristics of peat water and analyze the potential treating method for remove color and organic substances on peat water used activated carbon. The result showed color and organic substances on peat water was 1830 Pt/Co and 437,8 mg/L. High adsorption capacity on activated carbon could removed color and organic substance on peat water.Keywords: Peat water, adsorption

Abstract

Peat water in Indonesia has the potential a source of clean water because of its ample availability, but in terms of qualitatively it still does not meet the standards of clean water quality according to Permenkes No. 32 of 2017, such as organic substances and colors that are still high. This weakness can be overcome through processing using the coagulationflocculation method with the addition of natural coagulants. One of the natural coagulants that can be used in the coagulation-flocculation process is averrhoa bilimbi. Averhhoa bilimbi as a coagulant can reduce color parameters and organic matter in peat water because it has advantages in the coagulation-flocculation process due to its high acid concentration. This study aims to determine the effect of averrhoa bilimbi coagulant dosage and pH in removing organic matter and color in peat water. Keywords: Peat Water, Dosage, pH, Coagulation-Floculation, Averrhoa bilimbi.

Abstract

Solid waste is one of the environmental problems linked to our lives. University of Riau (UR) is a public university in Pekanbaru that can not be separated from the solid waste problems in which there is currently do not have alternative solid waste treatment. The purpose of this study was to determine the potential of treatment and economic potential. Method sample in campus 8 days consecutive shows, with location of sample solid waste faculty, office, canteen, hospital, road, and mosque. Analysis sample characteristic of proximate (water content, volatil, ash and fixed carbon) and garbage energy by using appliance bomb calorimeter. The percentage of the proximate analysis recapitulation waste mixed conditions the average percentage generated of 43,5% water content, volatile content of 45,7%, ash content of 2,2% and fixed carbon of 6,8%. Percentage recapitulation waste proximate analysis by components highest water content of 37,9% of organic waste, volatile content of 83,8% textile waste, ash content of 26,2% plastic waste, and fixed carbon of 96,8% waste iron. The highest calorific value waste is plastic waste that of 12671.56 cal/gr. Solid waste that has economic potential sale value to collectors obtained for Rp.107.735,-/day. Mass balance of weight solid waste with a daily average weight of 816 kg/day, which can be utilized 512 kg/day and the weight of solid waste being dumped into temporary disposal location 303 kg/day. Solid waste treatment for organic waste such as composting or animal feed, while the inorganic waste can be recycled and waste that has economic value can be sold directly to collectors, while the waste that is not used will be disposed to landfill the city of Pekanbaru.Keywords: characteristics, treatment, solid waste, campus, UR.

Abstract

In general, in the water treatment process, the process of separating water from solids occurs in the form of flocculant particles or sedimentation type II. Before planning to process river water into clean water, it is necessary to analyze the rate of deposition as the basis for the design criteria that will be used in the planning of the sedimentation basin. The sampling points are at a depth of 10, 30, 50, 70 and 90 cm and the sampling time ranges are 10, 20, 30, 45 and 60 minutes. The results obtained in order to achieve an efficiency of 70% in sedimentation processing, an overflow rate (Vo) of 1.3 m / h is required. Keywords: column settling, sedimentation type II, surface loading, papaya seeds

Abstract

The capital of each Province has development activities that increase along with increasing population density due to urbanization so that it results in reduce vegetation land. This condition causes an increase in surface temperature especially in the downtown area and triggers the Urban Heat Island (UHI) phenomenon. This study aims to analyze UHI phenomena based on surface temperature (LST) and index vegetation using a method the Soil Adjusted Vegetation Index (SAVI). Surface temperature extraction and land cover wereobtained from Landsat imagery. Based on the estimated surface temperature (LST) in 1996 the minimum temperature was 12,4oC and the maximum temperature was 25,8oC, while the average temperature was 19,1oC. in 2018 the minimum temperature is 19,2oC and the maximum temperature is 36,1oC, while the average temperature is 28,7oC.Keywords: Urban Heat Island, Surface Temperature, Normalized differentvegetation Index
