Most of water we used as rinse water, for example water used for bathing, for washing hands, to wash clothes, and more, approximately 70-80% of water consumption will turn into gray water. Along with the increasing water demand, the raw water needs to be processed is increasing as well. However, the increasing need for raw water is not followed by an increase in raw water, both in quality and quantity. These conditions encourage efforts to find alternative sources of raw water which more secure than others in terms of quality and quantity. One of its efforts is by making use again (reuse) efluent from wastewater treatment. The technology will be used to process must be cheap, effective, and not difficult in treatment. Technology used in this study is constructed wetland. The purpose of this research is measuring the treatment efficiency, determining the optimum operating conditions, determining the criteria for water reuse. This research is conducted in the laboratory using a constructed wetland with type of plant is Typha latifolia. Variations are made in this study are detention time (1day, 3days amd 5 days) and type of reactors (constructed wetland & aerated constructed weland). Each reactor is given wastewater feed derived from effluent of WWTP Bojongsoang. Parameters examined in this study are COD, BOD, pH, and temperature. Measurement of COD, pH, and temperature conducted every day, while the BOD parameter are done after the reactor reaching steady state conditions. Based on the measurements, it is known that the best detention time to remove organic matter is at 5 days with efficiency between 91,2-94,9%. Aerated constructed wetland can remove organic matter better than non-aerated reactor, with good significance removal at 1 day detention time.

The quality of a healthy environment is supported by the environmental determinants, one of which is the environmental carrying capacity. The purpose of this study was to find out the picture of environmental quality of Pudu river which located at Mandau, Bengkalis district, Riau province. Method used are the comparison between supply and demand of the land and the comparison between supply and demand of the water. At the first method, the purpose is to determine the carring capacity based on the comparison between availability and demand of the land by calculate the demand of the land and land carrying capacity status. And for the second method comparison based on the consideration of the availability of the water and the water carrying capacity for the residents around Pudu river. Analytical results showed that the land carring capacity status of Mandau districts is surplus, it means the availability of the land (SL) is higher than the demand (DL). While the status of water availability at Mandau district is surplus and it means the value of water availability (SA) is higher than the demand (DA).

MIKROALGA SEBAGAI BIOINDIKATOR KUALITAS AIR PERMUKAAN Studi Awal : Hubungan Antara Konsentrasi Pigmen dan Berat Kering dalam Penentuan Kandungan Mikroalga Pada Sampel Air Artifisial Rijal Hakiki

Abstract: Microalgae is the one of aquatic organism wich can be a bioindicators for surface water quality. Chlorophyll contain in a microalgae cell can be measured to know the abundance of microalga in a water body. Dry-weight biomass measurements is another method that can be used to know the abundance of microalga in a water body. both method have advantages and disadvantanges of each. In chlorophyll concentration measurements, the present of other compounds that can absorb light spectrum at measurements wavelength (Strickland and Parsons use 665 nm, 645 nm and 630 nm) result absorbance value higher than it should be. Turbidity level result by suspended particle content being a problem for dry-weight biomass measurements. Dry-weight biomass determination based on the approximation of chlorophyll content measurements was studied in this research. The Results of simple regression analysis showed that there is a fairly strong positive correlation between chlorophyll content and dry-weight biomass (Ra = 0.870), which has the tendency to follow the linear regression equation y = 302,35x + 17,121. Dry-weight determination based on approximation of clorophyll content can be applied to the sample of water that has suspended particle content tend to be constant and inert (did not produce subtances that can react with organic solvent when chlorophyll extraction process occurred). Based on the processed datas, it can be conclude that the influence of another suspended particle content in a sample of water is not statistically significant.

APPLICATION OF ULTRAVIOLET (UV) TECHNOLOGY ON WATER DECHLORINATION: INFLUENCE OF UV FLUENCE DOSE AND UV TRANSMITTANCE ON CHLORINE REMOVAL EFFICIENCY Maryani Paramita Astuti; Xie Rongjing

Water dechlorination is required to remove chlorine residual (free and combined chlorine) formed as byproducts of chlorination treatment. Ultraviolet (UV) dechlorination method has advantages compared to other dechlorination methods. This method uses a powerful photon energy generated by low pressure (LP) and medium pressure (MP) UV lamps to break chemical bond of the residual chlorine into reactive free radicals (•OH−) and (•Cl −). Studies are needed to evaluate its removal efficiency and the effect of treatment conditions on the efficiency before applying this method to practical applications. This study evaluates the effectiveness of medium pressure UV technology on UV dechlorination and investigates the influence of operation conditions (UV fluence and UV Transmittance) on chlorine removal efficiency. The impacts of both UV fluence and UV transmittance variations on chlorine removal efficiency were observed. Results of this study indicate that chlorine reduces upon exposure of UV radiation and chlorine removal efficiency increases with the increasing of UV fluence dose and UVT. The maximum UV fluence dose applied in this study (513 mJ/cm2) results in less than 25% of total chlorine reduction.

The purpose of this research is to analyze an integrated policy development of quality and environment management system. To achieve the purpose, researcher use multi dimensional scaling (MDS) method. MDS can use to analize sustainability status and leverage factors of tenant service. Result of this research show that tenant service reviewed from ecological, sociable, technological, institutional dimensions has less-sustainable status. However, when seen from its economical dimension, this tenant service matter is quite sustainable. Result of MDS describe that there were twenty three attributes which become to be leverage factor. The integrated policy development of quality and environment management system become to sustainable, if the area management direct policy to focus on institusional, technological, ecological and social dimensions.
