Sanitation facilities which can be used in reliable and sustainable ways for specific areas must be helpful to improve health condition and environmental quality. Several studies related to the development of sanitary handling specific areas, especially the coastal and swampy area have been carried out. One of the systems that can be applied to this area is Tripikon S. Tripikon-S is a vertical septic tank (cesspool) with three pipes used concentrically. Putri et al., (2013) said that in practice it is known that tripikon S can process 40% organic as BOD5 in septic pipe. According to this, it is important to make development of sanitation systems in specific areas This current research, therefore, attempts to modify Tripikon-S by adding venturi pipes and some baffle pipes to facilitate the occurrence of anaerobic-aerobic processes in Tripikon-S. The research objective was to observe the effect of the influent organic load removal efficiency of organic compounds in the reactor tripikon S without modification (reactor control) and tripikon S modification (reactor venturi). An experiment is conducted over the influence on COD of various influent concentrations of 1500 mg/L and 2000 mg/L and also that of various hydraulic retention times (HRT) of 24 hours, 36 hours and 48 hours. The measured parameters include pH, temperature, Dissolved Oxygen (DO), Chemical Oxygen Demand (COD), Volatile Suspended Solid (VSS), Nitrogen Total Kedjal (NTK), and Total Phosphate (TP). And the results of this study, the best COD removal efficiency in the reactor control occurs in the variation of influent concentration to 2000 mg/l COD and HRT of 48 hours with an efficiency of 63,04% at steady state. At the same variation with the variation in the control reactor influent concentration to 2000 mg/l COD and HRT of 48 hours obtained the best COD removal efficiency in the reactor venturi at 67,39%. The results of the Monod kinetics approach, is obtained ?max = 0,00049038 day-1 and Ks = 147 mg/l COD for reactor control on the variation of the influent concentration 1500 mg/l and the variation of the influent concentration to 2000 mg/l was obtained ?max = 0,00046318 day-1 and Ks = 5,574 mg/l COD. While the venturi reactor with a variation of the influent concentration of 1500 mg/l was obtained ?max = 0,00046523 day-1 and Ks = 69,06 mg/l COD. As for the variation of the influent concentration of 2000 mg/l was obtained ?max = 0,00053083 day-1 and Ks = 28,12 mg/l COD. And the most optimal results is the venturi reactor with a variation of the influent concentration to 2000 mg/l.
