KAJIAN TINGKAT PELAYANAN JARINGAM AIR BERSIH PDAM DI PERKOTAAN

Abstract

Water distribution sistem is made to meet the water requirment ini a city or community. In Semarang municipality, the management of water service is caned out by "Perusahaan Daerah Air Minum (PDAM) Kota Semarang". This condition result from inadequate flow, less pressure, discontinous flow, and poor quality of water Perumahan Dinas PJKA at Randusari - Middle of Semarang, one of villages served by PDAM Kota Semarang is also experiencing the same problem. The aim of this study is to evaluate the performance of water distribution service carried out by PDAM Kota Semarang ini location of the study by analyzing the water distribution ability in providing the minimum customers services covering water flow, water pressure and flow continuity. The Analysis method used is by analyzing flow based on minimum standart on reliability, resiliency, and vulnerability. Where as from water pressure analysis, flow continuity and discharge analysis in the checking of survey result to determined minimum standart. Flow gained from water meter record and water pressure measurement was compared to the result of theoretical with "Waterworks"/ Epanet program as the control. Based on the result of water meter record flow analysis, it wa found that the reability level was about = 47 %, where the system was ini failed condition for four months, the failure level varies ranging from = 5,50 % to 47 % deficit, and fifiom field survey the lowest pressure was = 0,10m and highest was = 4,10m, and the flow continuity was of woking 24 hours a day. The ration of the volume of flow result from water meter record and theoretical analysis was about = 52 % exceeding the theoretical analysis where it was about 43 % less from the result of theoretical analysis with the difference was not very significant. The correrlation coeficient was = 0,43. With a bit low interpretation. The ratio of water pressure resulting from measurement with theoretical analysis was high enough. All of the were result still less than the result of theoretical, where the minimum defict was = 42 meters and maximum deficit was = 47 meters. From the study, it can be concluded that thye service of water distribution of PDAM I in Housing of PJKA complex Semarang within the periode of the study was still satisfactory.
