242 | Identifikasi Hypoxia Di Teluk Hurun Lampung | This study was carried out to describe the characteristics of hypoxia in the tropical coastal sea. The general oceanographic surveys were conducted two times in Hurun Bay, 5-7 February and 17-19 February, 2003. And also, a day-night survey (25 hours survey) and the continuous monitoring of water temperature, current and meteorology were carried out. The monitoring data of water temperature indicated that the seasonal variation and the spatial in temperature in Hurun Bay were small. The difference in temperature between the surface and bottom water was less than 1.3 oC. The water temperature increased from February and the highest in April. It gradually decreased to late June and a sudden decrease occurred in the early July. The lowest temperature was observed in September and then it increased again. The seasonal variation in the thermal stratification was not happened. Instead of the weak thermal stratification, a sharp picnocline was formed around 20m in the dry season. The water below the picnoline was colder and more saline and contained less DO than the overlaying water. The cold water mass which has high salinity and lower DO was situated along bottom deeper than 20m on 17-19 July. The lowest DO in this water mass was 0.4 mg/l. Such a cold water mass appeared in early July and it propagated from offshore to the coast. The oxygen consumption rate of the water column was about 0.1 mgO2/L/hour in Hurun Bay. Comparing these oxygen consumption rates and the DO of water, if the oxygen supply was restricted, the water in Hurun Bay could become hypoxic easily. | Water temperature, Hypoxia, Dissolved oxygen | Arif Dwi Santoso, M.Eng dan Yuichi Hayami, PhD | |

Lately, in this area have been developed many cages for fish culture that produce organic waste in huge number. This research was conducted to know the status and dynamics of water quality in Jangari that receive organic waste in huge number.The research revealed that Jangari water body could be cited as an eutrophic water body. This conclusion was due to (i)-the concentrations of phosphorus was always higher than 0,016 mg?l-1P and nitrogen total was always higher than 0,711 mg?l-1N; (ii)-the density of fitoplankton in 25 cm depth was between 36.590?103 and 40.710?103 ind?l?1; whereas in 150 cm depth was between 29.620?103 and 36.370?103 ind?l?1. This phytoplankton community was dominated by Cyanophyta (70,9%-78,2%), especially. Microcystis sp and Oscillatoria sp. (iii)-the vanishing point of secchi disc was always smaller than 71 cm. During the research zooplankton was dominated by copepoda, cladocera and rotifera with density fluctuate between 34-394 ind?l?1. The eutrophic status for Jangari, will threaten the sustainable potency for tourism area; and therefore it was suggested to built one management for Cirata reservoir which could be hoped to plan, do and evaluate the development of Cirata appropriate to the potencies and carryng capasity of reservoir. | Jangari, organic waste, phytoplankton, euthrophic. | Yudhi Soetrisno Garno | |
250 | Penyisihan Timbal (Pb) Dari Tanah Terkontaminasi Dengan Proses Elektromigrasi | This study is trying to apply a new method in remediation electrokinetic by inserting conductive solution between cathode and soil to be treated. This is purposed in keeping the pH in low condition and preventing the precipitation of heavy metals in the soil adjacent to the cathode that often happen in the previous electrokinetic methods. Concentration of Pb (C0), period (t), concentration of conductive solution were selected as parameters, both with artificially contaminated sand and naturally contaminated soil experiments. The experiment with natural soil C0 = 975 ppm gave lower efficiency at 32,84% when it compares with sand as the medium, with the experiment in the same condition at 87,68%. Concentration of KCl also influenced the performance of system which was shown by the increasing in removal efficiency. The double increase of conductive solution concentration does not proportionally increase the flux of Pb. Although desorption in the natural soil take time longer than in the sand the removal efficiency relatively low. This is caused by the immobile state of Pb in the natural soil and the complexity of chemical reaction between heavy metals with surface of soil particle. | electrokinetic, lead (Pb), electromigration | Wahyu Purwanta | |
