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

The population growth in Bogor City is increasing every year, which can be seen from the population data from 2018 to 2022, increasing by 84,934 people with a population growth percentage of 2.07%. As the population grows, the demand for clean water will increase. This will also have an impact on the amount of domestic wastewater produced. In 2021, access to adequate sanitation in Bogor City will only be 75.35%, while it should reach 100% to achieve the SDG targets. Therefore, in order to achieve adequate sanitation, it is necessary to have a domestic wastewater treatment plant (WWTP) and assess IPAL so that the domestic wastewater produced can be safely discharged into the environment. A WWTP consists of several treatment units such as an intake building, an anaerobic pond, an aerobic pond, a facultative pond, a maturation pond and a sludge drying bed. The WWTP can be evaluated by comparing the effluent after treatment with quality standards, namely the Minister of Environment and Forestry Regulation No. 68 of 2016. The evaluation results show that several parameters still do not meet the quality standards for effluent to be discharged into the environment. These parameters are BOD and total coliform. Meanwhile, the percentage of TSS parameter removal was 57.14%, BOD 26.34%, COD 64.28%, Ammonia 69.88% and Total Coliform 99%.

Abstract

The village of Mekar Rahayu was selected as the site for the design of a wastewater treatment plant in Margaasih District. This sub-district is located in the Citarum River Basin, which does not yet have a domestic wastewater management system. Domestic wastewater is discharged into septic tanks or into drainage canals, which eventually ends up in rivers. This requires efforts to plan a domestic wastewater management system, considering that the domestic sector is the largest contributor to the pollution load in the Citarum River. The aim of this research is to determine an appropriate domestic wastewater management system to be implemented in the village of Mekar Rahayu. The research method is field observation and planning with reference to the regulations in force in Indonesia. The results of the research on local communal wastewater management systems can be applied in this region.  It is planned that 2 future community wastewater treatment plants will serve 25 out of 28 community units in this sub-district. 3 communes that do not fall within the service area of the treatment plant because the settlements are small and dominated by agricultural land, so they can still use the local system.  The calculation results for the total domestic wastewater generation are 118.16 litres/second. Based on the analysis of land requirements, ease of operation and other things, the selected series of domestic wastewater treatment plants are bar screen units, collection tanks, grit chambers, equilibration ponds, activated sludge, sedimentation II and disinfection.

Abstract

Inorganic coagulants are widely used in wastewater treatment. However, long-term negative effects have led to their replacement by organic coagulants derived from natural sources or environmentally friendly biocoagulants. In Indonesia, there are many plants that can be used as biocoagulants, one of which is the seeds of Moringa oleifera (Moringa oleifera). This research aims to analyse the influence of Moringa oleifera seed powder on COD, BOD and TSS parameters in laundry wastewater using the glass test method. The research variables include variations in doses of Moringa oleifera seed powder (0.8 g; 1.0 g; 1.5 g; 2 g; and 3 g). The study is analysed by comparing with standard limits and calculating the percentage removal of each test parameter. The results indicate that the different doses of Moringa oleifera seed powder can affect the levels of COD, BOD and TSS in wastewater. The optimum dose for reducing COD and TSS is 1.5 grams with a reduction percentage of 84% for COD and 94% for TSS. For BOD, the optimum dose is 1 gram with a reduction of 85%.

Abstract

The use of renewable energy for rural electrification in Indonesia has great potential, including the potential for energy from biomass. One way to convert biomass into renewable energy is through the pyrolysis process. Heating technology in pyrolysis is currently under development, one of which uses electrical energy with induction heating technology. Therefore, the aim of this research is to design a pyrolysis tool with a suitable induction heater, where this tool is powered by an electrical energy source. The pyrolysis tool is designed to use an induction heater that is varied by using a three-coil and a seven-coil heating element. The pyrolysis tool design was then realised in prototype form with a length of 1500 mm, width of 1000 mm and height of 1400 mm. Prototype testing was carried out using one heater, with each coil variation operated until the pyrolysis reactor reached the design temperature of 500°C within 120 minutes. The test results of the prototype pyrolysis unit using an induction heater with a three-coil heating element showed that the reactor temperature could not reach the desired target, but only reached a temperature of about 305.6°C in 120 minutes, with the electrical energy required for one test being about 5 kWh. Meanwhile, tests using an induction heater with a seven-coil heating element showed that the reactor temperature target of 500°C in 120 minutes could be well achieved. The electrical energy required for a test using a seven-coil heater is approximately 8 kWh.

Abstract

The construction of a wastewater treatment plant (WWTP) in Sayati Village is still required in order to dispose of the village's wastewater in an appropriate manner. One potential location for wastewater disposal is the Cikahayangan River. However, the discharge of sewage into the Cikahayangan River results in water pollution, which in turn disrupts the river's natural functions. It is imperative that Sayati Village devise a WWTP that can effectively and efficiently treat wastewater, while also adapting to the existing conditions of the village over the next few years. This is crucial to prevent any adverse impacts from water pollution. The BOD/COD ratio for Sayati Village is 0.809, indicating that the wastewater is treated biologically. The unit selected from the scoring method is activated sludge. However, the land available in Sayati Village is limited, so the WWTP unit refers to the 2022 Sanimas Technical Instructions, which describe a compact WWTP for 100 families with a land availability of 3 meters in width. The domestic wastewater treatment plant (WWTP) processing unit planned for Sayati Village, Margahayu District, consists of primary, secondary, and tertiary domestic processing units. The secondary processing unit selected is an anaerobic filter, which is in accordance with the 2022 Sanimas Technical Guidelines. The units that will be planned in Sayati Village are a bar screen, a grease trap, a screw pump, a grit chamber, an equalization tank, an anaerobic filter, a disinfection unit, and a sludge processing unit.

Abstract

In developing countries, high capital, operational costs, limited space are the main challenges to implement appropriate sludge treatment system. Thus, research about reutilization sludge are urgently needed. In this study, alum sludge from sedimentation basin of water treatment plant was dried and used as adsorbent for removal methylene blue from aqueous solutions. Alum sludge was charachterized by SEM-EDX, XRD, FTIR, particle size analyzer, surface area analyzer and pHPZC. The effect of various parameters such as: contact time (5-360 min), initial MB concentrarion (5-100 mg/L), adsorbent dosage (0.25-3.0 g/L), pH (4-10), temperature (20-60 0C) and water matrix (deionized, sedimentation basin effluent, river water, wastewater) were assessed. The result showed that removal efficiency has directly proportional with contact time, adsorbent dosage and pH, while an inverse relationship with initial MB concentration was observed. Removal efficiency up to 98% was achieved at MB 50 mg/L, AS 3 g/L, temperature 300, and pH 6.8. Isotherm and kinetic models fitted Langmuir model with capacity of 37.45 mg/g and pseudo-second-order model kinetic. Applicability test in various water matrix indicated that the utilization of low-cost adsorbent from non-modified dried alum sludge has potential for removal of methylene blue from low to moderate contaminated aqueous solution.

Abstract

Soreang District is the capital of Bandung Regency, with a population that continues to grow due to infrastructure development. This area falls within the Citarum River basin. The domestic sector is the largest contributor of pollutants to this river.  This area already has a wastewater treatment plant, which was built in 1991. The aim of this research is to evaluate the capacity of the constructed WWTP in order to determine whether or not it is still able to cope with the wastewater produced. The methods used are field observation, measurement and comparison with current design criteria. Based on the research results, the existing plant can only serve 250 heads of families. It is necessary to increase the capacity of the plant to cater for the growing population. The current condition of the plant is sub-optimal due to plant maintenance issues. In addition, the sewerage network is damaged and there are no experts available to operate the plant. The research findings call for efforts to rehabilitate existing wastewater treatment plants and increase their capacity. Domestic wastewater treatment will reduce the pollution load of the Citarum River.

Abstract

This study addresses the optimization of the supply chain network for the free lunch program in West Nusa Tenggara, Indonesia, aiming to enhance operational efficiency and service quality. The primary objective was to determine the optimal number and locations of mega-kitchens required to ensure efficient and timely meal delivery to various elementary schools across the region. Employing a combination of Greenfield Analysis (GFA) and simulation techniques within the anyLogistix software, the research systematically improved the supply chain configuration across five iterative simulations. The initial setup, with only one mega-kitchen, resulted in a 45% Expected Lead Time (ELT) Service Level, highlighting significant inefficiencies. Progressive iterations incorporated additional mega-kitchens, leading to substantial improvements in service levels and reductions in transportation costs. By the fifth iteration, the introduction of a fifth mega-kitchen achieved a perfect 100% ELT Service Level, demonstrating optimal operational efficiency with significant cost reductions. The findings confirm that strategic increases in the number of mega-kitchens, coupled with optimal location planning, significantly enhance the service delivery framework, meeting logistic demands while aligning with regional health and nutrition goals. This study illustrates the efficacy of advanced simulation tools in strategic planning and provides a scalable model for similar public health initiatives globally. Future research could explore more complex scenarios, including multi-modal transportation options and variable demand forecasts, to refine the operational efficiencies of such critical service delivery programs further.
