Tourism activities around the coast are growing rapidly, especially in the Petitenget Coastal area. Waste management by tourism actors around the area causes the contamination of the Petitenget Beach estuary. To overcome this, it is necessary to restore estuary water, one way is by utilizing the potency of the fragrant root plant as a phytoremediation agent. The purpose of this community empowerment program is to examine how effective the vetiver plant is as a phytoremediation agent for Petitenget Beach estuary water. This research was started by collecting water samples from the petitenget estuary and then conducting water quality research and testing water samples on Wangi Root plants using an artificial wetland system which was carried out for one month. From the research that has been done, it is known that the vetiver plant is quite effective in reducing the levels of chemical pollutants such as pH, BOD and COD, but this plant cannot reduce the microbiological levels contained in the water.

A study was conducted to evaluate the water quality parameters of pond water at Mymensingh Urban region. The water samples were collected from 30 ponds located at Mymensingh Urban Region during August to October 2010. The chemical analyses of water samples included pH, EC, Na, K, Ca, S, Mn and As were done by standard methods. The chemical properties in pond water were found pH 6.68 to 7.14, EC 227 to 700 ?Scm-1, Na 15.57 to 36.00 ppm, K 3.83 to 16.16 ppm, Ca 2.01 to 7.29 ppm, S 1.61 to 4.67 ppm, Mn 0.33 to 0.684 ppm and As 0.0011 to 0.0059 ppm. The pH values of water samples revealed that water samples were acidic to slightly alkaline in nature. The EC value revealed that water samples were medium salinity except one sample and also good for irrigation. According to drinking water standard Mn toxicity was detected in pond water. Considering Na, Ca and S ions pond water was safe for irrigation and aquaculture. In case of K ion, all the samples were suitable for irrigation but unsuitable for aquaculture.J. Environ.

Empowerment Program

Community empowerment is a form of development which directly involves the community. In community empowerment program, the position of the community is as program consumer but as program producer instead. Community empowerment aims to achieve community independence and welfare. Zakat is a subsystem which can support community empowerment program. It’s consistent with the objective of zakat, which is material and spiritual wellbeing. To encourage the success of the program, there should be support from various parties, including companion and social capital supports.The purpose of the present study was determining the direct effects of companion and social capital on participant of zakat recipient and its impact of economic performance of zakat-receiving micro businessman. The present study used primary data by involving 72 zakat-receiving micro businesspeople (mustahik businesspeople) in Wonosari Sub-district, Gunung Kidul Regency, Special Region of Yogyakarta. The research instrument was questionnaire with likert-5 scale which has high reliability and validity based on Cronbah Alpha and Kaiser-Meyer-Olkin values. The empirical model was analyzed using Structural Equation Modeling (SEM).The result of hypothesis test shows that companion and social capital affected the participation of zakat recipient, and the participation of zakat recipient affected the economic performance of zakat-receiving micro businessman.

Faecal Streptococci

A total of 111 water samples were drawn from 15 wells. These samples were subjected to bacteriological examinations to determine the suitability of the monitored wells as source for drinking water. Significant levels of bacterial pollution indicators were detected in the underground water samples during the period of study. Total bacterial counts ranged between 10-104CFU/ml. Faecal streptococci was the most common and detected in 9 6% of water samples. Lower percentages of samples (92, 55 and 45%) were contaminated with total coliforms, faecal coliforms and total clostridia, respectively. Faecal coliforms: faecal streptococci was less than 0.7 in 86% of the examined samples. Anaerobic bacteria were detected in the examined well water samples. Only 101 water samples were tested for anaerobic spore-formers and all showed positive results. Most examined wells do not meet the water quality standards for drinking water. Accordingly, the necessity of controllin bacterial pollution in ground-water through disinfection was clearly confirmed. Testing the underground water for more than one indicator represents an important approach for water quality assurance.

Surface And Groundwater

The Nomini Creek Watershed/Water Quality monitoring project was initiated in 1985, as part of the Chesapeake Bay Agreement of 1983, to quantify the impacts of agricultural best management practices (BMPs) on improving water quality. The watershed monitoring system was designed to provide a comprehensive assessment of the quality of surface and groundwater as influenced by changes in land use, agronomic, and cultural practices in the watershed over the duration of the project. The primary chemical characteristics monitored include both soluble and sediment-bound nutrients and pesticides in surface and groundwater. Water samples from 8 monitoring wells located in agricultural areas in the watershed were analyzed for 22 pesticides. A total of 20 pesticides have been detected in water samples collected. Atrazine is the most frequently detected pesticide. Detected concentrations of atrazine ranged from 0.03 - 25.56 ppb and occurred in about 26 percent of the samples. Other pesticides were detected at frequencies ranging from 1.6 to 14.2 percent of all samples collected and concentrations between 0.01 and 41.89 ppb. The observed concentrations and spatial distributions of pesticide contamination of groundwater are compared to land use and cropping patterns. Results indicate that BMPs are quite effective in reducing pesticide concentrations in groundwater.
