Abstract

The aimed of research was to identify and analyze the natural resources potential for mariculture development in Regency of Sangihe Archipelago. This research was carried out at Talengen waters in Central  Tabukan District and Manalu waters in South Tabukan District.  Research method was survey and the data was analyzed descriptively.   Primary data to be collected included water quality and socio economic data.  The second was obtained through interview to respondent chosen randomly.  Questionnaire was also used in collecting data.  Research result  showed that water quality at Talengen and Manalu waters was optimal and thus feasible for mariculture. However,  the development of mariculture at these locations should consider other utilization whether for fishery, ecotourism and conservation. Keywords:  mariculture, water quality, Talengen Waters, Manalu Waters

Abstract

The purpose of this study was to determine the current state of water quality in fish farming locations in the waters of Lake Tondano . Sampling points at each station are placed vertically in three predetermined points from the guard house to the front of the net.  The distance between one sampling  point to the next was ± 10 m. Water quality including physicals and chemicals parameters were analyzed at the Industrial Research Board of Manado. Sampling  point was made purposively as refers to the physiographic location in order to represent or describe these waters condition. This study was conducted for 2 weeks. Water sampling was done in three times, in the  morning, at noon, and in the evening. Direct measurement (in situ) was performed once a week that included DO, pH, temperature, and brightness, while the laboratory tests were conducted for 2 weeks which included phosphate, turbidity, Nitrite, Nitrate. Research results  showed that temperature, DO, pH, brightnes, phosphate, turbidity, nitrite, nitrate are still in good condition based on water quality standard stated in PP No.82 of 2001 . Keywords: Lake Tondano, water quality, chemical Parameter, physical Parameter

Abstract

The objective of this research was to measure and analyze the water quality parameters including temperature, brightness, pH, dissolved oxygen, total alkalinity, carbon dioxide and BOD in reservoir Embung Klamalu Sorong regency, and to know the factors that affected the water quality of Embung Klamalu. Measurement of water quality parameters was done in situ for temperature, brightness, pH and in laboratory for dissolved oxygen, total alkalinity, carbon dioxide, and BOD. The results showed the temperature at the five observation stations ranged from 26.2 to 29.8 0C, brightness 38 to 46 cm, pH 7.20 to 8.48 mg /L, dissolved oxygen from 7.20 to 8.48 mg / L, alkalinity 100 to 150 mg /L, carbon dioxide from 25.90 to 28.95 mg / L, BOD from 0.20 to 0.38. Refers to the standards of water quality according to the PP. 82, 2001, it could be concluded that water physical-chemical qualities in fish farming locations in the Village Klamalu were still in good condition. Keywords: Water physical-chemical quality, aquaculture, waduk Embung Klamalu

Abstract

This research was conducted by purposive random sampling method with 3 points. Data were analyzed descriptively by comparing the environmental quality standard based on the Ministry of Environment No. 51. 2004. Results of laboratory analysis was the content of Cadmium (Cd) was still below the allowable threshold. Compared to Cd content of fresh water which was 0.0002 mg/L, the Cd content found in this research was lower that was 0.0001 mg/ L.   Keywords: Kadmium (Cd), Logam berat, Baku Mutu, Pantai Malalayang, RS Prof Kandou.

Abstract

In this study, we determined the current condition of the water quality of Lake Tondano in terms of physical and chemical parameters in a fish farming locations on Lake Tondano of Toulimembet village waters. Determination of sampling points at each station is placed vertically at three predetermined points from the guard house toward the front of the net, the distance between one point to the next point was ± 12 m; whereas for the analysis of water quality parameters was done using an HORIBA water quality meters type U-536. Determination points were done by purposive sampling which refers to the physiographic location wherever possible in order to represent or describe these waters. The research was carried out for 3 weeks and was done in 3 stages, morning, afternoon and evening. For direct measurement (in situ) was performed once a week at the three points which included parameters pH, temperature, conductivity, DO, Oxidation reduction potential, turbidity, TDS, depth and GPS. Generally, the result of water quality analysis at the aquaculture still in the water quality standard PP No.82 of 2001. Keywords: Water Quality, Stick Net Cage, Lake Tondano, Aquaculture
