Abstract

Piles and pile foundations have been in use since prehistoric time. The commonest function of piles is to transfer a load that cannot be adequately supported at shallow depths to a depth where adequate support becomes available. When a pile passes through poor material and its tip penetrates a small distance into a stratum of good bearing capacity it is called a bearing pile. When piles are installed in a deep stratum of limited supporting ability and these piles developed their carrying capacity by friction on the sides of the pile, they are called friction piles. Many times the load carrying of piles results from a combination of point resistance and skin friction.  The load taken by a single pile can be determined by static load test. The allowable load is obtained by applying a factor of safety to the failure load. Although it is expensive, a static load test is the only reliable means of determining allowable load on a friction pile. In this case,“Cerucuk” are widely used in foundation engineering to increase bearing capacity of the foundation andreduce the settlement. Keywords : Pile foundation, bearing capacity, skin friction.

Abstract

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. Keywords: discharge, trend, climate change, landuse, anthropogenic

Abstract

The need for clean water in big cities is very dependent on water supply by water companies (PDAM). The increasing demand for clean water in big cities is proportional to the increasing of number population and industry, but not comparable to the clean water supply and quality of raw water available. PDAM has made various efforts to improve the quality of clean water services to the community. One of the effort is to improve the performance of water treatment plant (WTP). To support the improvement of the performance of WTP, required water quality monitoring at the intake location in use. This paper discusses the online and realtime water quality monitoring at the water intake location using a multi-probe digital sensor and GSM technology. This observation data is used as a comparative data analysis of laboratory data on raw water source PDAM Taman Kota (Cengkareng Drain). Keywords: air baku air minum, intake PDAM Taman Kota Cengkareng Drain, pemantuan kualitas air, multi probe digital sensor, teknologi online monitoring, Water Treatment Plant

Abstract

Jakarta Bay is a semi enclosed bay located in the northern coast of Jakarta Metropolitan City. Hydrologically 13 rivers flowing in the Jakarta region and there are three big rivers with significant discharge to the Jakarta Bay namely Citarum, Ciliwung, and Cisadane Rivers. Jakarta, as Indonesian capital city with population of 8.725.630 inhabitants, and another 15 million people live in the surrounded suburban of Jakarta, creates a significant anthropogenic impact to the environmental system. Limited infrastructures, such as no sewerage system and lack of industrial waste management, cause the rivers in this region have over their carrying capacity.Seventeen sampling stations were determined in the Jakarta Bay, consisting of 5 stations at the river mouths (estuaries) and other 12 stations in the bay spreading from the coastal to offshore areas. Water and sediment samples were taken during 2 monsoonal or seasonal variations, August 2006 for dry season and February 2007 for rainy season respectively. Additionally, samples were also taken in May 2007.Sediment distribution in the estuary consists mostly of black clay. The sediments clays were bad smell. In the coastal region and in the dry season, the sediments consists of black clay and at one sampling site (station S3) the sediment was bad smell. However, all sampling sites became bad smell in the rainy season. In the inner bay area, sediments were greyish green sandy clay with some shell fragments. In the outer bay, the sediments were dominated by greyish green clayey sand with some shell fragments. The black clay with bad smell is indicative of anthropogenic influence from Jakarta River Basin. C/N ratio of the sediments in the dry season ranged from 1 to about 4.2 where in the estuaries (at stations M1, M2 and M4) the ratio were higher compared to the inner and outer bays. The C/N ratio of suspended particulate matter ranged from the lowest ratio of 0.7 to the highest ratio of 17.7 at the bottom layer and lesser ranged of 0.7 to 9.8 at  surface layer. POC concentrations ranged between 50-650 µM and 50-900 µM, in February and May, respectively. High concentrations of POC exists along the coastline or estuaries then decreasing toward the sea. POC is distributed widely in February than that in May due to higher discharge from the rivers. The average TOC concentrations in February is lower than that in May, but the TOC load in February was much higher than that in May due to the big differences of river discharge and because the samples were taken a week after the big flood in Jakarta area (February 4th - 6th, 2007). Total organic carbon fluxes from the river to the bay in February and May 2007 were 107.6 T /day C and 42.7 T /day C, respectively. Key words : sediment, anthropogenic influence, C/N Ratio, POC, TOC, flux

Abstract

Water is a very basic need for humans, especially for cooking and drinking. With the rapid growth of population in particular need of clean water for the community also increased in numbers. The problem is with the poor quality of raw water for drinking water, then in addition to expanding its production costs, the result is often less good. One of the problems or issues that are often found in drinking water in the world these days that is the emergence of compounds called Trihalomethanes or THMs abbreviated, as a side effect of the disinfection process with a chlorine gas or hypochlorite compounds.Currently, to removal organic pollutants, ammonia, detergents, odor and other micro pollutants in drinking water, PAM is usually used by the process of manufacturing processes using adsorbsi Powder Active Carbon Adsorption, continued with physicals processing is the process of coagulation, flocculation, sedimentation and disinfection with chlorine. With increasingly high prices of powdered activated carbon, coagulant and flocculant chemicals, then the cost of treating drinking water to be increasing. To solve the problem above, one alternative is to develop clean water treatment technologies using a combination of biofiltration and ultrafiltration process, and to produce drinking water to proceed with processing using the process of reverse osmosis. Within the combination of biofiltration, ultrafiltration and reverse osmosis processes to treat the river water can be produced the drinking water with a very good quality without the use of chemicals for coagulation-flocculation process, and operational costs are relatively low. Key words : Air siap minum, biofiltrasi, ultrafiltrasi, reverse osmosis

Abstract

Denpasar is one of the number one tourist destination in the world. This city needs a lot of water resources with high quality to meet the needs of the hotel. While the Bali island with a relatively small area can not save the water resources in large numbers, the good management of water resources and efficiency use of water is realy needed. Hotel is one of the largest water users in the city of Denpasar. The water source is from deep ground water and PDAM with the same quality. If someday deficit water and sea water intrusion in Denpasar happened, the hotel will be accused as one major cause of this problem. To overcome these problems, environmentally friendly hotel management will be needed to achieve "GREEN HOTEL & RESORT" programs in Bali, such as water usage efficiency, water recycle and protect environment from wastewater polution. To achieve this without reducing the amount of water consumption, can be done by using the technology of wastewater reuse, with technology Waste Water Treatment Installation (WWTP) and continued with the water quality improvement technology using multi media filters, ultra-filtration or reverse osmosis. Key words : Hotel yang ramah lingkungan, re-use air limbah

Abstract

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 – 60 meter and 70 – 120 meter depth. Keywords : Groundwater, Electrical Resistivity

Abstract

In the national water resource management, the data is the basis for the calculation of water reserves. In a large scale and wide, searching the data will require substantial funding, as well as with the updates. Data colecting becomes a problem and not useful if not managed with the system efficiently and effectively. Technology occupies an important role in accelerating the work, such as remote sensing technology using a satellite to determine the condition of forests and water, or a weather that can see the concentration of clouds and wind movement. Determination of catchment areas of water and protected areas, may of them using remote sensing technology. Water treatment technologies for drinking water and the development of efficient recycling technology of waste water, is very supportive in increasing water use efficiency. Technological developments also influence government policy and the implementation of water resource management. National Policy of Water Resource Management is influenced by economic factors, environmental sustainability and socio-cultural conditions. The role of technology are  facilitate, accelerate and improve the efficiency of the process, so that the process can be more economical and environmental impact is reduced, and does not conflict with the socio-cultural conditions. Keywords : Kebijakan nasional sumber daya air, potensi sda, teknologi pengolahan air
