Abstract

Lake Kelapa Gading is an artificial lake located in Asahan district of North Sumatra province. Thepurpose of this study was to determine: 1) description of conditions of temperature, dissolved oxygenand pH vertically in the water for 24 hours, 2) production and consumption of oxygen in the waters ofLake Kelapa Gading. The study was conducted in March-April 2016 with preliminary and mainresearch activities. There are three observation stations are stations 1 (near KJA), station 2 (the areanear the settlement) and station 3 (outlet). The measured temperature ranges from 30-35 ºC.dissolved oxygen highest in the surface waters of 5.12 mg / l during the afternoon and the lowestoccurred at a depth of compensation of 0.64 mg / l when the weather is rainy. The measured pHvalue ranging between 6-9. In general there is a decrease in temperature, dissolved oxygen, and pHwith increasing depth. The highest percent saturation of 71.30 % in the surface waters. Comparisonbetween photosynthesis to respiration indicates that there has been a deficit in respiration is greaterthan the value of photosynthesis. dissolved oxygen concentration has reached a deficit at a depth of36.5 cm to reach at night.  Keywords: dissolved oxygen, lake, pH, saturation, temperature.

Abstract

Siombak lake (28 ha area) was a salty lake located in Medan coastal, Indonesia. Water fluctuation influenced by the sea tide. Therefore, it needed to do morphometry dynamical study as the first impression of lake physical characteristic. The purpose of this study was to understand the dynamical of Siombak lake morphometry. The research was done in September 2016. Lake mapping was done by making 100 line zig zag and draw with ArcMap. Bathymetry showed that the bottom of the lake was sloping at the center part of west and southeast of the lake, and steeping at north, south and east. Siombak Lake has shoreline length 2,535.78 m, with SDI value 2.70. Maximum length 756 m, with maximum width 246.15 m. Lake maximum depth was 17.7 m at MSL, 18.98 m at highest tide and 16.71 m at lowest tide, with average depth 5.33 m at MSL, 6.30 m at highest tide and 4.30 m at lowest tide. Lake volume was 783,607.16 m3 at MSL, 829,395.52 m3 at highest tide and 355,544.14 m3 at lowest tide, with water debit around 32.50 – 50.17 m3s-1. Water retention time was ± 4.33 – 6.75 hours
