The achievement of safe sanitation access is about 7.42 % in 2018, that indicates high risk of faecal contamination from unmanaged onsite sanitation system and has not been fully supported by faecal sludge service. This paper described the study of characteristic of onsite sanitation and faecal sludge for review potential of integrating of sludge handling with improved communal wastewater treatment. Faecal sludge quality were observed from pit latrines and communal septic tank, then analysis method apply cluster analysis and through close loop approach consider treatment and disposal for resource recovery. The pilot model of combined treatment of wastewater and faecal sludge was developed by anaerobic digester with a maximum 5% sludge loading, then further treatment by biofilter system and sludge drying bed. The quality of treated water can meet COD and nitrogen as effluent standard, biosolid reached a stabilization index of 40 - 60%, water content of 50-60% and less Coliform bacteria content. The characteristics of faecal sludge strength to be handled will be influenced bytechnical aspect or environment. The integrated system could be applied to manage wastewater and faecal sludge and its by products, mainly for rural area has not been catered by faecal sludge service.

Indonesia had launched the strategic plan for water and sanitation provision postmillennium development goal 2015. The universal access of 100% for water supply and sanitation sector has been designated to be reached by 2019. This study is aimed to model the partnership approach that is suitable to reach the designated sanitation sector targets based on some success story of some base technology application. The decentralized- and community-based technology that could be replicated should take into consideration all aspects that relate to social capitals. It also identifies and analyses the vital cross-cutting themes and success factors, highlights gaps in the current knowledge, and identifies high-potential areas for partnerships. The grounded theory was used to systematically code, constant comparison, render the categories. Mixed method and technique were used for data analysis. The developed model consists of ten out of twenty collaboration factors that generate variables to structure the model social-capital-based partnership with six dynamic similarity trends of growth and two different trends of growth. This model demonstrates that social connections might drive the collaboration activity to generate benefit from the social connection. The 100% universal access to the sanitation target might be achieved if the model is applied correctly.
