<p align="justify">Problems often occur in the use of membrane technology is formation of the precipitate/Foul on the surface and pore membrane. Fouling can inhibit the filtration process so we need a process to remove the precipitate. EFM (Enhanced Flux Maintenance) and CIP (Clean In Place) is a membrane cleaning process using chemicals. In this research the effect seen EFM and CIP processes on the performance and effectiveness of the membrane in stages replace the conventional treatment (coagulation-flocculation-sedimentation). Analysis of the performance of the membrane is determined by the parameters of water quality (physical and chemical) and operational parameters (flux, TMP-Transs Membrane Pressure, frequency EFM,% Recovery). The study was conducted on a pilot scale using a mixture of raw water source (Cikapundung-Cikalong) with raw water turbidity levels are fluctuating. The results obtained in this study is more effective ultrafiltration membrane in a designated turbidity with efficiency reached 99.98% while the conventional system produces turbidity removal efficiency of 97.30%. Raw water turbidity levels influence the TMP, the higher the turbidity of raw water then an increase in the value of the TMP significantly. In conditions of high turbidity levels confounding material also contained organic matter, Fe, Mn in the form of dissolved or suspended. Based on the analysis results of FTIR and SEM-EDX fouling formed on the surface and pore membranes including types of organic and inorganic fouling. EFM frequency of at 7 days/once is less effective in removing organic fouling (organic substances) and inorganic fouling (Fe and Mn) can be seen from the decline %recovery of significant membrane. The optimum operating conditions in the processing using membrane in condition 4 with flux = 55 LMH, the frequency EFM 4 days, and% recovery of 95.7%. The operational costs of conventional treatment in IPA Badak Singa to the old processing of Rp.905/m³, and for processing new Rp. 940/m³. While the cost of processing operations using the lowest membrane (low cost) are the conditions of 5 at a cost of Rp. 919.7/m³. <p align="justify">
