Groundwater is water that comes from the ground. Groundwater comes from rain, snow, sleet, and hail that soaks into the ground. The water moves down into the ground because of gravity, passing between particles of soil, sand, gravel, or rock until it reaches a depth where the ground is filled, or saturated, with water. Groundwater is stored in the ground in materials like gravel or sand. Water can also move through rock formations like sandstone or through cracks in rocks. Groundwater is one of solution to overcome a problem of the need of drinking water in the PadangLuas Area, because the availability of surface water is not enough. The objective of research is finding out characteristic and condition of ground water in PadangLuas, Tanah Laut district. To meet the objective, it was applied method of geophysical technology, namely electrical resistivity method by injecting current into the ground through current electrodes that are grounded at the earth's surface and measuring the difference of the electrical potential between the potential electrodes. Based on data processing, modeling and interpretation, it was gained result concerning the existence of aquifer in PadangLuas area that is predicted to occupy between 30 Ã¢â‚¬â€œ 60 meter and 70 Ã¢â‚¬â€œ 120 meter depth.Ã‚Â Keywords : Groundwater, Electrical Resistivity

METODA PENGHILANGAN ZAT BESI DAN MANGAN DI DALAM PENYEDIAAN AIR MINUM DOMESTIK Said, Nusa Idaman

Small amounts of iron and manganese are quite common in domestic water supply because of the presence of iron and manganese in the soil and rock formations through which the water passes in reaching the point of use. Iron and manganese is characterized by red-brown staining of bathroom fixtures and laundry, and cause taste and odor problems. Iron and manganese are brought into solution by biological reactions under anaerobic reducing conditions. When the water is exposed to air or oxygen, oxidation of iron and manganese occurs slowly, forming objectionable colloidal precipitates. The deposition of these precipitates will stain plumbing fixtures, interfere with laundering, and cause difficulties in water distribution systems by supporting growth of microorganisms such as clonotrix and crenotrix that can clog pipelines and cause taste and odor problems. Processes in which oxidation is followed by removal of suspended solids can effectively remove soluble iron and manganese from water. Three common processes for removing iron and manganese are: aeration-filtration, chlorination filtration, and potassium permanganate-manganese greensand filtration. This article describes these processes and present result from pilotÃ¢â‚¬â„¢s studies of iron and manganese removal from water.Ã‚Â Kata kunci : zat besi, mangan, aerasi, kkhlorinasi, filtrasi, mangan zeolit.

The textile industry is one of the most popular industries in Indonesia. Although itÃ¢â‚¬â„¢s giving a positive value towards economic value, it also contributes a bed effect towards environmental quality. One of those industries is small-scale laundry industry located in Kelurahan Sukabumi Selatan, West of Jakarta. The lack of land and money, most of the jeans laundry industry throws away their wastewater straight to the river system without any process. The present study describes the application plastic media called bio-ball as a biofilter supporting media for treating of jeans laundry industry wastewater using combined anaerobic and aerobic process. The type of reactor that is used in this research is a continuous flow biological reactor which has total volume 195 litter and divided into 5 zones, i.e. presedimentation , 2 anoxic zone, aerobic zone and post sedimentation zone. Reactor effluent is recirculated into presedimentation zone with hydraulic recycle ratio (HRR) 1:1. Seeding is done in a natural way by directly flowing the domestic wastewater into reactor with retention time 72 hours, until a biofilm layer is formed on the surface of bio-ball media. Acclimatization is done gradually by replacing domestic with laundry jeans wastewater in 72 hours retention time, until domestic wastewater was 100 % replaced, The main research were conducting by continuous operation under condition 72 hours, 48 hours and 24 hours retention time. The result of experiment shows that within the combined anaerobic and aerobic process using bio-ball plastic media under conditions 1 - 3 days retention time, the removal efficiency of COD 78 Ã¢â‚¬â€œ 91 %, BOD 85 Ã¢â‚¬â€œ 92 %, Total Suspended Solids (TSS) 80 Ã¢â‚¬â€œ 93 %, and Colour 48 Ã¢â‚¬â€œ 57 % respectively.Ã‚Â The longer retention time has resulted in higher removal efficiency

This paper describes some of the general condition of the oceanographic parameters in the Strait Matak, Anambas Archipelago. The data flow is obtained by direct measurement by using a current meter types RCM-7. Simulation models using Mike 21. Mike flow pattern is divided into two seasons, namely west season (January) and the east season (August) and flow patterns ahead of the tide when the season is generally moving west to wards the south, it demonstrates the role of strong tidal influence the movement of waterin the study area. Flow velocity in the strait just before the tide on the west season reaches 1m/s.Ã‚Â Flow patterns at high tide on the west season looks still moving toward sthe south. The maximum flow velocity in the strait when the tide reaches 0.32 m/s, while the average speed in the area of the model is 0.12 m/s. Low tide towards the current pattern is still moving towards the south, it reinforces the notion that in addition to tidal windsare also very significant role in moving the flow, in this case that the current is moving toward the south. Flow velocity just before low tide reaches 0.85 m/s. Flow patterns at low tide shows the differences in the three previous conditions, the current in the strait to move out to the north toward the South China Sea. In condition slow tide, the tida lmore dominantly than the wind, this proved to even though the wind toward the south, the currents inthestraitis moving toward snorth along the tidal flow leading to the South China Sea. Flow velocity is quite varied location of modeling; flow velocity at low tide reaches 0.5m/s, with the average 0.15 m/s.Ã‚Â Keywords: current and direction, wind, tide, model.

The hydrological character of the rivers in Java has changed. The trend flow of upstream rivers in Java declined. Significance level of the trend decline in the upstream was large enough. This indicates that the basic flow (base flow) from these rivers has been reduced. The cause of the trend decline in river flow is strongly influenced by a combination of the effects of global climate change and the influence of anthropogenic. The influence of climate change is marked by decreasing annual rainfall. While anthropogenic influences include changes in land use, reduced water catchment area, increasing population pressures and settlements. To identify which factors are most influential between the two factors are very difficult to do because of limited data on land use change.Ã‚Â Keywords: discharge, trend, climate change, landuse, anthropogenic
