Abstract

Eris Society in the village of utilizing the waters of Lake Tondano as a place to fish cultivation in floating net system and step on floating net karamba system. Karamba unit developments and floating net cages in the area of ​​cultivation step on the less controllable negative impact on the aquatic environment such as pollution of water quality. For this study aims to measure the quality parameters including pH, temperature, brightness and analyzed water quality parameters including turbidity, dissolved oxygen, ammonia and phosphate so that the water quality conditions in the Village of Lake Tondano District Eris Eris known. From the results obtained by the temperature at a depth of 0.5 meters from surface water ranged from 25.3 to 28.3 º C, at a depth of 0.5 meters from the lake bottom ranged from 24.7 to 28 º C, the brightness ranges from 182-325 cm, turbidity ranges from 7 - 16 NTU, the pH at a depth of 0.5 meters from the water surface ranged from 6.89 to 8.09, at a depth of 0.5 meters from the lake bottom ranged from 6.93 to 8.03, dissolved oxygen ranged from 7.10 to 7.52 mg / L, ammonia ranging from 0.03 to 0.14 mg / L, and phosphate ranged from 0.02 to 0.12 mg / L. Temperature, brightness, pH, dissolved oxygen and phosphate at the sites are still in good condition that is still in accordance with the water quality standard. For turbidity and ammonia has passed the threshold water quality standard. This is presumably due to domestic wastewater effluent from surrounding communities, causing decomposition which affects the water quality conditions. However the waters in the village of Eris can be used for aquaculture. This is evidenced by the persistent cultivation of fish in the Village District Eris Eris.

Abstract

ABSTRACTThe study was done at the culture site and in the laboratory. The former covered water temperature and pH in the spawning, nursery and rearing ponds, in the morning, 06:00-07:00, at noon,12:00-13.00, and in the afternoon 17:00 to 18:00. Measurements were taken for 2 weeks. The latter included Dissolved Oxygen (DO), Ammonia, Nitrite, Carbon Dioxide (CO2) and turbidity. Water samples were analyzed in the Laboratory of Freshwater Aquaculture Center (BBAT) Tatelu, North Minahasa. Results showed that water temperature, pH, DO, CO2, turbidity, ammonia and nitrite were in the suitable range for the freshwater lobster culture, except that DO, CO2, turbidity, ammonia in the spawning and rearing ponds on March 14, 2011 were either lower or higher than the National Water Quality Standard for aquaculture.Keywords: Water Quality Parameter, Laboratory, Pond, Water Quality Standard.ABSTRAKPenelitian dilakukan di tempat budidaya lobster dan di laboratorium. Pengukur-an lapangan meliputi suhu air dan pH di kolam pemijahan, pendederan, dan pembesar-an, pada pagi hari (06:00-07:00), siang hari (12:00-13.00), dan sore hari (17:00-18:00). Pengukuran dilakukan selama dua minggu. Pengukuran laboratorium meliputi Oksigen terlarut (DO), Amonia, Nitrit, Karbondioksida (CO2) and kekeruhan. Sampel air dianali-sa di laboratorium Balai Budidaya Air Tawar, (BBAT) Tatelu, Minahasa Utara. Hasil menunjukkan bahwa suhu air, pH, DO, CO2, kekeruhan, amonia dan nitrit berada da-lam kisaran yang sesuai untuk budidaya lobster air tawar, kecuali bahwa DO, CO2, ke-keruhan, amonia di kolam pemijahan dan pembesaran pada 14 Maret 2011 berada le-bih rendah maupun lebih tinggi daripada standar bakumutu air nasional untuk budidaya.Kata kunci: Parameter kualitas air, laboratorium, air kolam, bakumutu.

Abstract

ABSTRACT The objective of this research was to analyse the water physical-chemical qualities at aquaculture area in Lake Tondano North Sulawesi. Water quality was measured in situ and in laboratotium. In situ measurement included temperature, pH, and turbidity, while in laboratory, water quality measured included dissolved oxygen, nitrogen, phosphate. It was found that water temperature ranged from 25 - 27 o C, turbidity 0.20 - 4,0 m, and dissolved oxygen 5 – 9 mg/L, Nitrogen 0,0334 - 0,0697 mg/ L, phosphate 0 - 0,0219 mg/ L. It was concluded that water quality around Paleloan Village was appropriate for aquaculture activity. Keywords: water quality, aquaculture, Paleloan Village

Abstract

ABSTRACT The objective of this research was to detect the pollution level of Tondano River based on temperature, BOD, turbidity and dissolved oxygen parameters. Research was conducted at Ternate Baru Village, Manado City, from January to March 2013. Water sample was taken by purposive sampling at three stations at 08.00 AM, 11.00 AM, and 15.00 PM, each with two sampling points. Water quality was measured in situ for temperature and turbidity while dissolved oxygen and BOD were analysed in laboratory. Research results found temperature ranged from 270C-27,8 0C, turbiduty 37,9 - 150 NTU, dissolved oxygen 6,3 - 7,5 mg/L and BOD 15,5-44,5 mg/L. Based on Water Quality Standard Grade II PP No. 82, 2001, BOD and turbidity at Ternate Baru were high. It was concluded that water quality of Tondano River at Ternate Baru Village was categorized polluted. Keywords: water quality, pollution, Tondano River, Ternate Baru Village
