Abstract

The purpose of this research was to provide data on waters physical and chemical parameters, proper areal map, carrying capacity, and potential production of seaweed. Research method used was spacial approach through direct measurement in the field and through laboratory analysis. Ten observation stations were established purposively at Desa Arakan waters. Samples were collected four times at two weeks interval. It was found that water temperature was 31–31,25 ºC, flow rate 5,97–11,09 cm/det., dissolved oxygen 5,34–6,45 mg/l, pH 7,7–8,1, salinity 32,5-33 ppt, nitrate 5,02–5,25 mg/l, phosphate 0,01–0,14 mg/l, water depth 1,3–16,5 m, velocity 1,3–4,5 m, tide 0–283 cm with Mean Sea Level 75,6 cm. bottom substrate consisted of coral sand and muddy sand. Proper culture area based on SIG analysis was 134.64 ha in which very proper areal was 68.40 ha, proper 66.23%. while proper areal was 66.23 ha. Based on carrying capacity analysis, proper sustainable site was 126.57 ha. This area could support 1.054 long line measuring 20x60 cm each. Seaweed potential was 3363,7 ton per ha or 4.4 ton/ha/year or 4.4 ton/ha/planting season. Keywords: marine seaweed, water quality, SIG, sea water, SIG, carrying capacity, production

Abstract

The purpose of this research was to analyze the physical and chemical parameters of waters (temperature, turbidity, pH, dissolved oxygen, nitrate, phosphate, ammonia and BOD) around net cage culture area at Peleloan Village, Minahasa Regency and to determine the suitable culture site supporting optimal growth of fish. water quality was measured at three sites. Temperature, turbidity, and pH were measured in situ while dissolved oxygen, nitrate, phosphate, ammonia and BOD were analised in laboratorium. Research results showed water temperature at all observation sites ranged from 25.5-28.2 0C, turbidity 2.02-3.15 m, pH 6.8 – 8.2, DO 7.41-7.77 mg/L, nitrate 0.3-0.5 mg/L, phosphate 0.00-0.4 mg/L, ammonia 0.13-0.77 mg/L. Based on water quality standard criteria stated in PP No. 82, 2001, temperature, turbidity, pH, DO and nitrate at fish culture area were suitable for floating and stick net cage cultures but ammonia at all sites of observation, phosphate at site I at 0.5 m from the bottom and BOD at site III at 0.5 m from the bottom were exceeding the standard criteria. Keywords: water physical and chemical Parameters, floating net cage, Lake Tondano, Paleloan Village

Abstract

The purpose of research was to analyze water quality parameters including temperature, brightness, pH, dissolved oxygen, alkalinity, and carbon dioxide in tourism area Embung Klamalu, Sorong Regency, West Papua Province. Measurement of water parameters was done in situ and in laboratory. It was found that on week two measurement, water temperature ranged from 27.2 to 28.9 ˚ C in the morning and 28.2 to 30.2 ˚C in the afternoon; brightness from 6.0 to 0.7 and from 7.0 to 7.8, pH 6.0 to 6.8 and from 7.0 to 7.8, DO from 6.10 to 7.35 mg/L; total alkalinity 100 – 160 mg /L and 100 - 140mg/L, carbon dioxide 50.92 to 85.93 mg/L and 55.90 to 75.92 mg/L. It was concluded that parameters of pond water in tourism area Embung Klamalu were still in suitable for aquaculture activity. Keywords: water quality, pond, Embung Klamalu, Sorong Regency
