The treatment condition is not working well, because of the smell bad, polluter, and the effluent have nondegradable material (COD and VSS) with high concentration, that is COD and VSS in the amount of 6727,27 mg/L and 2915 mg/L. This Research exactly do it processes domestic wastewater according to elektrocoagulation process on laboratorium scale. NaCl concentrated variation, is using 0 gr/L, 0,5 gr/L, 1 gr/L and detention time (td) variation, is using 45 second, 55 second, 60 second, with rapid mixing variation are 150 rpm, 180 rpm, 200 rpm. Rapid mixing in flocculation unit is 20 rpm and detention time of sedimentation is 2,26 – 3,02 hours. Research result get optimum operational condition with NaCl concentrated 0,5 gr/L, rapid mixing 180 rpm, and detention time 55 second, with % removal COD is 95,43%, BOD 95,05%, TSS 98,98%, Detergen content 90,08%, Oil and Grease 84,10%, TKN 65,30%, VSS 99,21%, Phosphate 62,88% and Turbidity 96,30%. If with NaCl concentrated 0 gr/L, rapid mixing 180 rpm, and detention time 55 second (as aqualizer), with % removal COD is 95,54%, BOD 95,93%, TSS 98,94%, Detergent 86,92%, Oil and Grease 31,80%, TKN 59,70%, VSS 99,38%, Phosphate 25,34% and Turbidity 98,70%. Abstract in Bahasa Indonesia: Normal 0 false false false IN X-NONE X-NONE /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin:0cm; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} Kondisi IPAL Gedung Syarif Thajeb (M) saat ini kurang berjalan maksimal karena sering menimbulkan bau dan effluent memiliki kandungan materi nondegradable (COD dan VSS) yang masih menunjukkan konsentrasi yang tinggi, yaitu COD dan VSS sebesar 6727,27 mg/L dan 2915 mg/L. Sehingga dalam penelitian ini dilakukan pengolahan limbah dengan proses elektrokoagulasi secara kontinue dengan menggunakan reaktor elektrokoagulasi dalam skala laboratorium. Pada proses ini digunakan konsentrasi NaCl untuk memperbesar penguraian Al terlarut, variasi konsentrasi NaCl yang digunakan adalah 0 gr/L, 0,5 gr/L, 1 gr/L dan variasi waktu tinggal 45 detik, 55 detik, 60 detik serta variasi kecepatan pengadukan 150 rpm, 180 rpm, 200 rpm. Kecepatan pengadukan di unit flokulasi adalah 20 rpm dengan waktu pengendapan selama 2 jam. Pada hasil penelitian diperoleh kondisi operasional optimum dengan konsentrasi NaCl 0,5 gr/L, kecepatan pengadukan 180 rpm dan waktu tinggal 55 detik, dengan % penyisihan COD sebesar 95,43%, BOD 95,05%, TSS 98,98%, Detergen 90,08%, Minyak Lemak 84,10 %, TKN 65,30%, VSS 99,21%, Total Phosphat 62,88% dan Kekeruhan 96,30%. Sedangkan jika digunakan dengan konsentrasi NaCl 0 gr/L, kecepatan pengadukan 180 rpm dan waktu tinggal 55 detik (sebagai pembanding), maka % penyisihan COD sebesar 95,54%, BOD 95,93%, TSS 98,94%, Detergen 86,92%, Minyak Lemak 31,80%, TKN 59,70%, VSS 99,38%, Total Phosphat 25,34% dan Kekeruhan 98,70%.
