Abstract

Clean water and sanitation are two things that cannot be separated users of drinking water or clean water will definitely produce waste water, no less than 85% of clean water turns into waste water. Indonesia has a percentage of adequate sanitation services at 74.58%, including 7.42% for safe sanitation. These figures are accompanied by a high percentage of open defecation practices, approximately 9.36%, equivalent to 25 million people, which places Indonesia as the third highest in the world for open defecation rates. Households that have access to sanitation are those connected to the Wastewater Treatment System (SPAL), which is pumped and disposed of at the Fecal Sludge Treatment Plant (IPLT). 272 IPLTs built in 2018, only 8 are operating optimally. Local governments establish a regional entity as a service provider (operator), which can take the form of UPTD, BLUD, and BUMD. This research aims to identify performance indicators for each institution, identify regional potential for each institution, recommend strategies and analyze the business model of each institution. The analysis used in the research was to obtain regional potential using the interview method. Data analysis using the ATLAS.Ti application was then analyzed narratively. The results are useful for knowing strategic recommendations for Waste Water Treatment Systems (SPAL) and business development for each institution.

Abstract

Domestic activities around DAS Citarum cause significant pollution and environmental damage. One of the strategies implemented is the treatment of domestic wastewater through SPALD-T on a settlement scale and one of the beneficiaries is Sindangpakuon village. Over time, there have been changes in the management structure, roles and activities of KPP as managers. An analysis was carried out to assess the impact of the completeness and activity of the KPP on its sustainability. Data collection was carried out through observation, interviews, questionnaires in analysing technical, institutional, financial, social-community participation, environmental aspects using RAPFISH and SWOT methods to diagnose and develop sustainability strategies. In the technical aspect of SPALD-T RW 06, 07 is considered quite sustainable and RW 10 is not sustainable, in the institutional aspect of all RWs is considered quite sustainable, in the financial aspect of RW 06 is considered quite sustainable and RW 07, 10 is not sustainable, in the social-community participation aspect of all RWs is considered quite sustainable and in the environmental aspect of RW 06, 07 is considered quite sustainable and RW 10 is sustainable. A strategy that can be applied by all SPALD-T is an aggressive strategy that uses strength to take advantage of opportunities. The research is expected to be one of the inputs for stakeholders in assessing and preparing sustainability strategies for community-based domestic sanitation programmes.

Abstract

Faecal sludge management is crucial in supporting sustainable development in urban areas. Regional Regulation No. 10 of 1991 regulates the role of Faecal Sludge Treatment Plant managers in facing challenges related to increasingly limited dry sludge storage capacity. Therefore, this research explores the potential for utilizing faecal sludge processing products such as maggot and Kasgot organic fertilizer. This research includes identification of the product supply chain, analysis of market acceptance, and financial analysis using Net Present Value (NPV) and Benefit Cost Ratio (BCR). In the Duri Kosambi IPLT case study, the processed sludge produced and not yet managed could reach 100 m3 per month. Through comprehensive management by IPLT managers, semi-dry processed sludge can be utilized and distributed via waste trucks to BSF farms in Jakarta City. Based on estimated calculations, the mud is used as animal feed (maggot) as much as 8 tons/month and Kasgot organic fertilizer (50 tons/month). Based on market acceptance, the market volume for faecal sludge management products reached IDR 169,091,699/ 100 m3 with a growth rate of 7% every month. The factors influencing aspects of market acceptance consist of 9 factors, with the highest indicators influenced by market demand variables. Faecal sludge management using BSF is financially feasible based on an NPV analysis of 1.2 billion/year and a BCR of 1.2.

Abstract

One of Bandung's residential slum areas, the Maleer sub-district, has been identified as a priority sanitation area, particularly in terms of wastewater management. In order to improve wastewater management in the slum area, technical and non-technical aspects are considered. This study aims to know the wastewater management policy factors that affect the sustainability of the wastewater management system and to propose a policy model in the slum area. A convenience sampling method was used to collect data from 99 respondents and 7 institutional respondents using a self-administered questionnaire. Partial least square structural equation modelling (PLS-SEM) was used to test the proposed model. The sanitation risk index value in a slum area of Maleer district was 283. Some factors affecting the sustainability of sanitation system arranged by value correlation were (0.325) for technical aspects, (0.283) for community participation, (0.272) for management institution and (0.174) for financial aspect, respectively. The existing policy model only included technical and financial factors, while community participation and management institution were not included in the existing policy. In developing a new model of slum sanitation to achieve sustainability, factors in the form of active community participation and presence of management institution need to be added.

Abstract

Slum areas in Pontianak, such as the Panglima A. Rani and Kayu Manis areas along the Kapuas River, face significant domestic wastewater management challenges, including river pollution and health issues. To meet the SDGs 2030, the city government plans to implement a domestic wastewater management system using both centralised and localised approaches. In this study, the Unified Theory of Acceptance and Use of Technology (UTAUT) and structural equation modelling (SEM) are used to analyse the factors influencing the acceptance of sanitation technologies. The research includes both quantitative and qualitative analyses using PLS-SEM in Smart PLS V.3.0. The results indicate that performance expectancy, effort expectancy, social influence and facilitating conditions influence community acceptance, with the highest path coefficients observed for facilitating conditions (41.26%), followed by social influence (32.19%), effort expectancy (21.46%) and performance expectancy (5.09%). Facilitating conditions and social influence have a significant impact on community participation, with P-values < 0.05 and T-statistic values > 1.96.
