Abstract

The location of Faecal Sludge Treatment Plant (FSTP) that is not planned properly can result in a low level of FSTP service, a lack of supply of faecal sludge to the FSTP, and environmental pollution problems due to illegal dumping. In this study, an analysis of important aspects in determining the location of the FSTP and the application of the Geographical Information Systems (GIS) was carried out in optimizing the coverage of FSTP services in Bandung City. The identification of criteria and weight of criteria in determining the FSTP location was performed using a pairwise comparison method against the criteria and sub-criteria obtained from literature review and stakeholders input. The results of the identification criteria were then mapped and analyzed using ArcMAP 10.8.1. Based on the identification results, there are 5 criteria that are declared important in selecting FSTP locations, namely technical, institutional, regulatory and policy, financial, and public acceptance. Further identification of the 5 criteria found 22 sub-criteria and there are 10 sub-criteria including those that can be used in selecting and optimize the service coverage of the FSTP locations in this study. Based on the GIS mapping, an optimum service coverage to serve all areas in Bandung City that has not been served by a wastewater piping system was obtained by using 3 FSTP locations, namely Districts of Gedebage, Cinambo, and Andir with the total required area of 26,400 m2 in 2041. The optimum service coverage is obtained based on the sub-criteria of the shortest distance and the fastest travel time from the FTST location to the farthest service areas.

Abstract

Domestic wastewater generated from various types of buildings has been recognized to be different to some extent. This research aimed to know the quality, quantity, fluctuation of quality, and fluctuation of quantity of domestic wastewater discharged from office buildings. The composite samples were taken from two office buildings. The black water and gray water were taken from Building A with number of people 53 persons, and the mixed wastewater was taken both from Building A and Building B with number of people 900 persons. The fluctuation and quantity of wastewater were measured every hour from 7 am until 4 pm during the working time. The results showed that the quality of wastewater from office building contained 176 to 238 mg/L COD, 73.06 to 106.51 mg/L TN, and 3.66 to 7.70 mg/L TP with the average of C:N:P ratio was 100:42:2.56. Quantity of wastewater discharged from office buildings were from 39.61 to 49.93 liter/person/day. COD concentration changed significantly during the working time with mean ± standard (252.5±89). The quantity of wastewater varied over time and the peak discharge for black water and gray water were 2.85 litter/person/hour and 3.74 liter/person/hour, which occurred during the beginning of working time and the praying time of muslim Indonesian culture. It suggests that the domestic wastewater from office buildings has specific characteristics and it contains high concentration of nutrient that is required appropriate advanced technology for treating this kind of wastewater.

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

This research aimed to find the effect of initial concentration and hydraulic retention time (HRT) on modified septic tank (MST) performance in treating wastewater from an office building. The synthetic wastewater used had an average COD:TN:TP ratio of 84:28:1, adjusted to office building wastewater characteristics. The experiment was executed under steady conditions using three variations of HRT (12, 24, and 36 hours) and different initial concentrations of COD (106, 252 and 432 mg COD/L), TN (35, 85 and 146 mg N/L) and TP (1.26, 3 and 5.14 mg P/L). The result showed that the MST removed 82% to 92% of COD, 41% to 60% of TN, 45% to 61% of NH4, and 39% to 55% of TP. The maximum removal was achieved at 36 h of HRT, COD:TN (3:1), and COD:TP (84:1). One-way ANOVA showed that the initial concentration and HRT had significant effects on the performance of MST (p < 0.05). This suggests that appropriate control of the initial concentration and HRT in the MST can effectively remove organics and nutrients from office building wastewater.

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.

Abstract

Indonesia has a decent sanitation service percentage of 74.58%, including safe sanitation of 7.42%. This figure is accompanied by a high percentage of open defecation behavior, which is around 9.36%, equivalent to 25 million people, making Indonesia ranked 3rd in the world for the largest number of open defecation. Households that have access to sanitation are those that have a connection to a Waste Water Treatment System (SPAL) that is desludged and disposed of at a Fecal Sludge Treatment Plant (STP). However, of the 272 sewage treatment plants built in 2018, only 8 were operating optimally. The local government forms a regional device or institution as a service provider (operator) in the form of UPTD, BLUD, and BUMD. BUMD institutions are more sustainable than other institutions. This study aims to identify performance indicators at the DKI Jakarta BUMD Perumda Paljaya institution, identify regional potential at the DKI Jakarta BUMD Perumda Paljaya institution, and analyze the development of the DKI Jakarta BUMD Perumda Paljaya institution business model. The data collection method is using the interview method. Data analysis using the ATLAS.TI application. The results are useful for business development of DKI Jakarta BUMD Perumda Paljaya institutions. Keywords: institutions, Perumda Paljaya DKI Jakarta, regional potential, performance indicators, ATLAS.Ti, business model development
