Unsafe sanitation conditions that do not guarantee hygiene can cause diseases such as diarrhea, typhus, skin diseases, malaria and so on, can also cause environmental contamination such as eutrophication and damage river diversity. Increasing access to sanitation in slum organizations cannot be realized easily because it must meet access to appropriate technology, affordable, sustainable, and targeted sanitation according to physical and environmental conditions. One technology that can be applied to slum organizations is Tripikon-S which is a technology made by Prof. Ir. Hardjoso Prodjopangarso which consists of three (tri) concentric (con) septic (S) pipes (pi), as an alternative to domestic wastewater treatment for certain areas. Some modifications that have been made to Tripikon-S are the addition of bioballs which result in COD removal efficiency of 66%. Another modification that has been made is the addition of a coconut fiber filter to the outlet pipe which is applied in the Kalimantan area, but its efficiency has never been tested in a laboratory. This study aims to conduct laboratory-scale testing on the modification of tripikon-S with the addition of bioballs to large pipes (8-inch pipes) and coconut fiber filters on the Tripikon-S outlet pipe for the processing of black water waste, mixed domestic wastewater, and to analyze the kinetics that occur in the reactor modification. Seeding and acclimatization were carried out in batch conditions with variations in COD loads of 500 mg/L, 750 mg/L and 1000 mg/L to analyze the kinetics that occur using the Monod model. Samples in the batch treatment were taken every hour. SEM analysis and microbial community analysis were carried out to determine the attachment of bacteria to the bioball filter media. The study was continued with a continuous phase, running was carried out with a 48-hour HRT and testing the removal performance on variations of black water waste and mixed domestic liquid waste. The µmax value was obtained at 0.0524/hour and Ks 942.277 mg/L COD/hour, and the yield value was 2.57088. For COD variations of 500 mg/L, 750 mg/L and 1000 mg/L, the degradation rate (k) was obtained respectively of 0.053/hour, 0.0537/hour and 0.0442/hour. The results of the microbial community analysis showed that there were 744 types of bacteria with the most species attached to the bioball being Clostridium pasteurianium, and Plaudibaculum fermentas and the dominance of the Holophagae and planctomycetia bacterial classes indicating that anaerobic conditions had been created in the bioball reactor. The phyla that dominate the bioball are the protobacteria, acidobacteria, bacterioidota and actinobacteria phyla which are generally found in the activated sludge system, proving that the bacteria attached to the bioball are waste degrading bacteria and the system has been formed according to its designation. Black water removal in both reactors obtained better results in the modified reactor with COD removal efficiency of 67.76% and TSS 87.51% while Ammonia removal was better in the control reactor. The test results showed no significant increase in performance in black water waste treatment. Comparison between black water and mixed domestic wastewater variations showed that black water waste produced better removal efficiency, with a p-value of 0.03569 (<0.05) indicating that there was a difference in efficiency in the application of Tripikon-S modification for black water and mixed domestic wastewater treatment.
