Abstract Waste management, especially organic waste, remains a significant challenge in the Greater Bandung This study aims to analyze the role of community-based waste management in reducing organic waste generation at the Sarimukti landfill and its impact on the lifespan of the Saguling Reservoir.
The research method involved analyzing primary and secondary data, including the amount of organic waste generated, the quantity of chicken feed produced from maggot processing, chicken farmers' income, and electricity production at Saguling Reservoir.
Primary data were obtained from surveys of 26 Waste Bank Units throughout Greater Bandung and PT PLN Indonesia Power UBP Saguling, which initiated the Saguling Berdaya program.
The results showed that the program successfully managed community organic waste using the maggot bioconversion method from 2023 to July 2025, achieving a total of 887.
03 tons, with an average of 28.
61 tons/month converted into layer chicken feed.
The production of 50 kg/day of fresh maggots was used to feed 1,200 laying hens, which produced 62 kg of eggs/day.
In 2024.
PT.
PLN IP UBP Saguling successfully collected 660.
48 tons of organic waste.
This result contributed to reducing the organic waste load at the Sarimukti landfill by 0.
09% of the total organic waste, which was 724,598 tons.
This implementation had a significant economic impact, as farmers were able to save Rp122,148,000.

The Sarimukti TPA can accommodate 1,390 tons/day of waste, which accounts for a total of 1,400-1,600 tons/day of waste transported.
fact, only 30-40% of the waste is transported by the Regional Environmental Management Agency (Dinas Lingkungan Hidup/DLH), while the rest remains uncollected, resulting in people dumping waste into rivers.
According to the Citarum River Basin Water Resources Management Plan .
, the amount of waste dumped into the Citarum River is 8,763 mAper day.
The waste received at the Sarimukti landfill consists of a mixture of organic and inorganic materials, making it difficult to process effectively.
Ideally, waste should be sorted based on its type and potential for utilization or economic value.
With proper processing, only residual waste or the remains of sorted waste will be disposed of at the landfill.
Such efforts may significantly reduce the volume of waste at the Sarimukti landfill, allowing it to operate at full capacity and preventing the community from dumping waste into the Citarum River, which flows into the Saguling Reservoir.
A reservoir serves as a water storage facility and a water supplier (Putri et al.
The operational lifespan of reservoirs may be compromised by sediment accumulation (Juldah et al.
, 2.
The Saguling Reservoir is currently facing a critical reduction in its operational lifespan.
The Saguling Reservoir, located in West Bandung Regency, serves as the site of the Saguling Hydroelectric Power Plant (PLTA).
Based on data from the Ministry of Environment and Forestry (KLHK, 2.
, households are the primary source of waste in Indonesia, accounting for 56.
24% of the total, with organic waste being the most significant component, reaching 39.
23% of the total national waste.
Organic waste originates from living organisms, such as food scraps and leaves (Adzim et al.
, 2.
, and is naturally biodegradable (Rahmat et al.
As the population increases, the volume of waste, especially household organic waste, has also increased significantly.
Larger quantities of organic waste emphasize the importance of more integrated and source-based organic waste management.

Figure 2.
Waste Composition Based on Waste Type Source: Ministry of Environment and Forestry, 2024 Organic waste that is not managed correctly has the potential to cause significant environmental impacts, particularly by accelerating sedimentation and eutrophication in water bodies such as reservoirs and rivers.
According to Smith et al.
, the entry of organic matter into water bodies increases nutrient concentrations particularly nitrogen and phosphorus which triggers excessive algae growth .
lgal The decomposition process of algal biomass then consumes large amounts of dissolved oxygen, resulting in hypoxic conditions that are detrimental to aquatic organisms (Diaz & Rosenberg, 2.
In addition, settled organic particles contribute to the sediment load, accelerating siltation and reducing reservoir storage capacity, thereby threatening the reservoir's lifespan.
Organic waste management at the source is a crucial strategy to mitigate sedimentation in the Saguling Reservoir and alleviate the pressure on the Sarimukti Currently, organic waste at the Sarimukti landfill is not processed separately, but is mixed with other waste in the active zone.
According to Hoornweg and BhadaTata .
, reducing organic waste directly at the source through sorting and independent processing can reduce the burden on landfills while also reducing the risk of environmental pollution from leachate and greenhouse gas emissions.
Sorting organic waste upstream also has other positive impacts on inorganic waste.
Separated inorganic waste has better value and facilitates the recycling process in the future.
Therefore, source-based organic waste management such as household composting or maggot bioconversion by the community is a more effective and sustainable solution than final disposal in landfills (Zurbrugg et al.
, 2.
The use of Black Soldier Fly (BSF) maggots as high-value economic biomass larvae can serve animal feed, particularly for laying hens (Khan et al.
, 2.
In addition to reducing waste volume, this technology supports the circular economy and strengthens local food security.
PT PLN Indonesia Power UBP Saguling, through the Saguling Berdaya program, has become the first company in Indonesia to provide a comprehensive alternative solution to waste management issues, covering the upstream, midstream, http://endless-journal.

LITERATURE REVIEW
Organic Waste from Saguling Reservoir Waste is material left over from human activities or natural processes that has no further value and is discarded by its owner (Sigit, 2.
Organic waste originates from living things humans, animals, and plants such as food scraps, leaves, and agricultural waste.
This substrate decomposed easily through microbial activity within a relatively short time.
In practice, organic waste is classified into two types:
, food scraps, fece.
and dry .
, dry leaves, twig.
based on their moisture content (Prodyanatasari et al.
, 2.
Inorganic waste consists of non-living materials, such as plastic, metal, glass, and dust, which are generally difficult or very slow to decompose naturally.
The decomposition process takes decades or even hundreds of Community-Based Organic Waste Management Figure 3.

explain that Community-Based Development Plus (CBD ) is a framework for rural community empowerment that emphasizes strengthening community capacity through the application of good governance principles and social innovation.
It is based on empirical evidence from the implementation of existing community empowerment policies and concepts.
The framework assesses the success of rural development not only through program implementation, but also through resilienceAemeasured by four key elements: strong institutions, financial support, sustainability, and assistance.
By integrating these elements.
CBD aims to foster adaptive, inclusive, and sustainable community-based Waste Management Hierarchy The waste hierarchy is a framework that ranks waste management strategies from the most sustainable to the least desirable: prevention, reduce, reuse, recycle, recovery, and disposal.
Its goal is to maximize material benefits while minimizing final waste, supporting energy conservation, reducing greenhouse gas emissions, and preserving resources.

Waste Management Hierarchy The implementation of waste management at Saguling Reservoir aligns with the following waste management hierarchy.
Prevention & Reduce At this stage, the community is encouraged to sort organic and inorganic waste at the source, such as household organic waste, to facilitate effective waste This is essential to prevent mixing, ensuring that organic waste remains within an optimal management flow.
Reuse & Recycle Recycling in the form of composting: Black Soldier Fly (BSFL) larvae, also known as maggots, can consume organic waste, reducing its volume by approximately 50% in a short period (Amrul et al.

, 2.
Recovery Transforming waste into two value-added products maggots as feed and frass as fertilizer is a powerful form of value recovery.
This reduces reliance on disposal and fosters a circular economy that supports sustainability (Sukardi.
Disposal By implementing the above approach, the amount of organic waste entering landfills is significantly reduced, making disposal a last resort when other operations fail to address residual waste (Pasymi et al.
, 2.
Community-based organic waste management is a participatory approach that positions the community as the primary actor in sorting, processing, and utilizing waste at the local level (Wydya & Kartika, 2.
Bioconversion using Black Soldier Fly (BSF) larvae or maggots is a widely used method because it can process organic waste quickly, efficiently, and in an environmentally friendly manner.
Maggots are the larvae of black soldier flies that can convert organic material from waste into economically valuable products (Auliani et al.
, 2.
Organic waste biomass is converted into larvae and residue.
The larvae contain approximately 35% protein and 30% crude fat.
The protein in these insects is of high quality and serves as an important source of feed for livestock (Dortmans et al.
, 2.
BSF larvae can reduce waste volume by up to 50% within 12Ae15 days, producing high-value biomass, such as maggots for animal feed, and residue .
as an organic fertilizer (Amrul et al.
The conversion of organic matter yields protein-rich larvae for feed and nutrient-rich material for natural fertilizer.
In a community-based organic waste management scheme, the bioconversion process using Black Soldier Fly (BSF) larvae typically begins with the collection and sorting of organic waste at the source by community members, ensuring that only suitable materials .

enter the cultivation Next, the sorted waste is placed in a biopond container, where BSF larvae are fed daily under optimal temperature (A27Ae30 AC) and humidity conditions to maximize larval growth.
Within approximately 12Ae15 days, the larvae can reduce the volume of waste by around 50Ae70% while increasing the protein and fat content in their biomass (Satori et al.
, 2.
After that, the larvae are harvested and separated from the residue .
using a sieve.
The larvae are prepared as animal feed, and the frass is processed as fertilizer.
The residue also undergoes secondary fermentation to reduce the organic nitrogen content and increase stability as a biofertilizer (Amrul et , 2.
The Effect of Organic Waste on Reservoir Sedimentation and Electricity Production Time Organic waste that enters water bodies undergoes decomposition by aerobic bacteria, which utilize dissolved oxygen in the water (Iswanto et al.

reduces the effective storage volume of The reduction in the effective capacity of the reservoir can limit operational flexibility, for example, during peak operating hours and the volume of water available for hydroelectric power plants (HPP.
Additionally, sediment can abrade turbines/intakes, reducing the operational efficiency of HPPs and increasing operational maintenance costs (Dorji & Ghomashchi, 2.
, thus increasing electricity production time.
METHOD
This research was conducted in four regions: Bandung City.
Bandung Regency.
West Bandung Regency, and Cimahi City.
These locations were selected because they deposit waste at the Sarimukti landfill.
The research sites include one sub-district in Bandung City, six sub-districts in Cimahi City, one village in Bandung Regency, and six villages in West Bandung Regency.
The types of data used are primary and secondary data.
The primary data required includes the amount of organic waste generated, the amount of chicken feed produced from maggot processing, the income of egg-laying chicken farmers, and data on sedimentation and electricity production at the Saguling Reservoir.
Primary data were obtained through surveys of 26 waste banks and PT PLN Indonesia Power UBP Saguling, which served as the program organizer.
In addition, secondary data on reservoir sedimentation were also required.
Secondary data was obtained from a 2022 study by PT Indra Karya on sedimentation at the Saguling Reservoir.
Primary data was collected through direct observation and interviews with the community and relevant agencies.
The sampling method used was purposive sampling, whereby samples were selected based on specific objectives or characteristics relevant to the study.
Interviews were conducted with the communities managing maggot farming and PT PLN Indonesia Power UBP Saguling, which served as the program organizer.
The amount of household organic waste produced in the area around the Saguling Reservoir and processed through maggot farming was analyzed descriptively and quantitatively.
The calculation was as follows.
Organic waste requirements for = Number of maggot farming locations x (Maggot maggot feed farming operation days/365 day.
x Organic waste requirements in one cycle After obtaining this value, we can determine the impact before and after maggot The analysis can be done using the following formula (Sumarwoto, 2.

Explanation:
iQ = Impact Qdp = Environmental conditions at time t "with the project" Qtp = d Environmental Conditions at time t "without the project" RESULTS AND DISCUSSION Saguling Empowerment Program The Saguling Berdaya Program was launched in 2023 in response to the current serious challenge of waste management in the upstream region, particularly due to low public interest and awareness regarding waste sorting at the source.
The Saguling Berdaya Program is an initiative of PT PLN IP UBP Saguling, providing an integrated solution from upstream to downstream processing.
In the upstream phase, the Saguling Berdaya Program prioritizes a circular economy approach by establishing 26 BSUs across the Greater Bandung area to manage community waste in the vicinity of the Saguling Reservoir.
The waste managed consists of organic and inorganic waste.
Organic waste is the most significant component of total household waste accumulation in this case study, specifically in the Greater Bandung area, which encompasses Bandung City.
Bandung Regency.
West Bandung Regency, and Cimahi City.
If not properly managed, organic waste can cause various environmental problems, including air pollution due to unpleasant odors, increased greenhouse gas emissions .
ainly methane from decomposition in landfill.
, and the spread of disease, facilitated by the growth of vectors such as flies and rats.
Therefore, community-based organic waste management through the waste bank mechanism is a highly promising strategy for reducing environmental burdens while enhancing local economic value.
Additionally, the community is increasingly encouraged and accustomed to sorting waste at home for productive utilization by the nearest BSU.
One of the innovations implemented in organic waste management by PT PLN IP UBP Saguling through the Saguling Berdaya program in 26 BSUs throughout Greater Bandung is maggot cultivation, specifically the larvae of the Black Soldier Fly (BSF), also known as Hermetia illucens.
The use of BSF maggots produces feed that is used to feed residents' laying hens and sold commercially.
The utilization of organic waste to create an economically valuable product in the form of maggots for animal feed is a solution at the processing stage carried out by PT.
PLN IP UBP Saguling.
BSF
maggots are known for their extraordinary ability to consume and decompose large amounts of organic waste in a relatively short time.
This process begins with sorting organic waste from households or markets, including food scraps, vegetables, and This waste must not be mixed with inorganic or hazardous materials such as plastic, metal, or chemicals, to avoid disrupting the maggot life cycle and maintain the quality of the final product.
After sorting, the organic waste can be fed directly to the maggot colony or fermented first using a bioactivator solution to increase its nutritional value.
Maggots are kept in special containers placed in a closed cultivation area with good air Under ideal conditions, maggots can consume approximately twice their http://endless-journal.

round 40Ae45%) and fat .
round 25Ae30%), making them a highly potential feed source for livestock, especially laying hens.
Once they reach optimal size, the maggots are harvested and usually dried through sun drying or a special oven to prevent the growth of pathogenic The dried maggots are then ground into flour or fed whole as a mixture in layer feed rations.
Research shows that maggot-based feed can replace some or even all animal protein components in commercial feed without reducing egg production performance or egg nutritional quality.
Additionally, the use of maggots as feed is more economical and environmentally friendly because it utilizes locally available organic waste.
At both the upstream and processing stages, an approach at the downstream level is also necessary.
The Saguling Berdaya program has consistently carried out education as a strategic step to build public awareness of the importance of responsible waste management.
This education aims to change the mindset and habits of the community, which has been littering, especially in waterways that flow directly into the Citarum River and Saguling Reservoir.
These educational activities are conducted through various environmental conservation events held regularly, such as the Citarum Festival.
Environment Day, and National Waste Awareness Day (HPSN), as well as education from an early age through the Waste Management Go to School program.
Waste Management Go to School is the first educational initiative in 32 junior high schools in West Bandung Regency, focused on early waste management This program has successfully reached 16,352 students with direct instruction on the importance of sorting waste, processing waste, managing household waste, and understanding the environmental impact of littering.
Organic Waste Generated by Communities Around Saguling Reservoir that is Managed Organic waste managed by 26 waste banks under PT PLN IP UBP Saguling totaled 323,006 kg in 2023, 661,236 kg in 2024, and 481,174.

Community-Based Development at Saguling Reservoir Organic waste management around Saguling Reservoir remains a significant challenge, directly affecting the quality of its ecosystem.
The application of the Community-Based Development Plus (CBD ) concept in waste management through the establishment of 26 waste banks offers a strategic framework for achieving sustainable environmental management based on community empowerment.
The existence of 26 waste banks around the Saguling Reservoir has established an institutional network that functions as a hub for coordination, education, and operational waste management.
This institution has facilitated waste sorting at the source through the maggot system and the distribution of processed products for animal feed and fertilizer.
Surveys of maggot waste bank programs in several regions of Indonesia indicate that household participation increases when there are rules for periodic collection, profit sharing from product sales, and reporting of maggot and frass production indicators that mark a functional institution (Auliani et al.
, 2021.
Sari et al.
, 2.
CBD is a key factor in ensuring program sustainability.
At Saguling Reservoir, funding for waste bank activities is sourced from member contributions, village funds, and the sale of derivative products, such as maggot feed and chicken eggs.
Studies show a measurable increase in income among actors involved in utilizing organic waste at 26 waste bank sites through income diversification via the sale of compost, maggot feed, and eggs.
The processing of organic waste using black soldier flies (Hermetia illucen.
effectively reduces the organic load entering reservoir waters, thereby reducing the potential for eutrophication and extending the reservoir's lifespan.
Based on the analysis provided, the sustainability of the Community-Based Development Plus (CBD ) program at Saguling Reservoir is demonstrably strong, covering economic, social, and environmental aspects.
From a financial perspective, this program not only reduces the volume of organic waste but also generates new income streams for the community through the processing of waste into high-value products such as maggot feed, eggs, and compost.
This model creates a self-sustaining local economic cycle, minimizing reliance on external funding and supporting the continuous operation of the waste bank.
Thus, financial sustainability is achieved through income diversification and the application of circular economy principles that transform waste into valuable assets.
Socially and institutionally, the existence of 26 community-managed waste banks reflects the strong independence and empowerment of the community.
This institutional network forms a robust foundation for coordination, education, and program sustainability.
Partnerships with various parties, including PT PLN IP UBP Saguling and the local government, reinforce the legitimacy and operational stability of this initiative.
Environmentally, this program directly contributes to improving the quality of the Saguling Reservoir ecosystem by reducing waste entering it, in line with the waste management hierarchy.
Through the synergy of strong institutional frameworks, stable funding, and sustained support, this program not only http://endless-journal.

successfully addresses waste issues but also serves as a replicable model for community empowerment.
Technical assistance and guidance provided by PT PLN IP UBP Saguling, environmental organizations, local governments, and universities have strengthened the capacity of waste bank managers.
Program evaluations show that waste banks receiving regular assistance were able to significantly increase waste conversion using maggots and access local markets for feed and fertilizer more quickly.
Waste banks that receive regular assistance tend to have more diverse product innovations and can survive despite fluctuations in feed or egg prices.
The integration of the four pillars of CBD in 26 waste bank units has resulted in synergies that not only reduce the volume of organic waste entering reservoirs but also create local economic value chains.
The integration of the four pillars of CBD in 26 waste banks has resulted in synergies that not only reduce the volume of organic waste entering reservoirs but also create a local economic value chain.
Ie The cycle of organic waste Ie maggots Ie layer chicken feed Ie layer chicken eggs Ie consumption of eggs reflects circular economy principles that are adaptable to the rural context.
With a solid institutional foundation, stable financing, sustainable practices, and consistent mentoring, this CBD model has the potential to be replicated in other areas facing similar challenges.
The implementation of waste bank management groups in the area around the Saguling Reservoir serves as a key strategy in advancing integrated waste management, particularly organic waste.
Through a partnership with PT PLN IP UBP Saguling, the waste banks focus not only on reducing waste volume but also on enhancing added value by processing waste into valuable products.

Environmental Impact of Organic Waste Management by the Community Around the Saguling Reservoir Through the Saguling Berdaya Program Based on data obtained from the Ministry of Environment and Forestry .
, projections were made for organic waste generated in Greater Bandung.
Organic waste in the form of food scraps and twigs entering the Sarimukti landfill amounted to approximately 724,598.
9 tons/year.
The total waste generated at the Sarimukti landfill in 2024 is 1,384,226 tons/year, with organic waste accounting for 52.
The 26 waste banks established by PT PLN IP UBP Saguling, spread across West Bandung Regency.
Bandung Regency.
Bandung City, and Cimahi City, are working to reduce the amount of organic waste entering the Sarimukti landfill.
In 2024, these waste banks are projected to manage approximately 660.
48 tons of organic waste This organic waste is processed into maggots, which serve as feed for laying However, the amount of waste converted into animal feed by BSF maggots in 2024 is 410 tons.
Based on Table 2, the total organic waste collected by the waste bank over the past three years amounts to 1,463,162 kg.
Meanwhile, the organic waste processed by maggots into animal feed reaches 28.
61 tons/month.
The amount of organic waste decomposed by maggots is 28.
61 tons/month.
These maggots are then utilized as feed for laying hens.
A total of 50 kg of fresh maggots is used daily to feed 1,200 laying hens, which are capable of producing approximately 62 kg of eggs per day, equivalent to around 1,080 eggs per day.
In 2024, the organic waste collected annually by 26 Waste Banks covered by PT PLN IP UBP Saguling's organic waste program totaled 660,486 kg/year, equivalent to 48 tons/year.
During the same year, the total organic waste entering the Sarimukti landfill reached 724,598.
9 tons/year.
Based on this, the waste banks contributed to reducing the burden of organic waste entering the Sarimukti landfill by 0.
09% in 2024.
Economic Impact of Organic Waste Management by the Community Around the Saguling Reservoir through the Saguling Berdaya Program The utilization of organic waste in animal feed products through the Saguling Berdaya program by PT PLN IP UBP Saguling offers economic potential for residents, as farmers no longer need to purchase industrial feed.
The Saguling Berdaya Program has 122 members, including 26 Waste Banks across Greater Bandung, which have managed 1,475,539 tons of organic waste between 2023 and June 2025.
Through maggot farming, the concept of a circular economy can be realizedAeorganic waste is processed into feed for chickens, which then produce eggs that can be consumed by residents or sold.
This cycle not only reduces the amount of waste disposed of but also increases food self-sufficiency and community welfare.
Substituting industrial feed with maggot feed has benefited chicken farmers.
Within one month, they can save up to IDR 122,148,000.
00, with monthly egg sales revenue of IDR 305,370,000.
00 and a net profit of IDR 74,826,960.
Overall, the Saguling Berdaya program serves as a concrete example of the application of circular economy principles.

valuable resources, reduces dependence on synthetic feed and fertilizers, and strengthens food security and the local economy.
However, the model also faces challenges, including the need for technical training, strict sanitation management, and policy support from local governments to enable broader and more sustainable The effectiveness of this system has been demonstrated in various regions, including Indonesia, which continues to face significant issues with large-scale household organic waste.
The waste management model, which utilizes communitybased waste banks that integrate BSF maggot cultivation, demonstrates that this approach is not only effective in reducing waste volume and producing high-value products but also empowers communities and creates economic value (Maharani & Dinanti, 2.
Maggot bioconversion opens up local economic opportunities through the sale or utilization of maggot products and processed fertilizers.
Therefore, community-based waste management through maggot bioconversion reflects circular economy practices that integrate social, economic, and ecological aspects of The success of this approach is determined by residents' awareness in sorting waste at the source, the availability of cultivation facilities, and collaboration among community members.
The Effect of Organic Waste on Reservoir Sedimentation and Electricity Production Time Organic waste management based on utilization at the source, currently being implemented in the Saguling Berdaya Program through the cultivation of Black Soldier Fly (BSF) larvae at waste banks, plays a crucial role in reducing the amount of organic waste that ends up in water bodies, such as the Saguling Reservoir.
This reduction in organic waste input has a direct impact on sediment control.
The organic material that would usually settle at the bottom of the reservoir is reduced, thereby slowing down the rate of siltation.
With the reduction of sediment in the Saguling Reservoir, the water intake and processing capacity will increase, allowing for more efficient electricity production at the Saguling Hydroelectric Power Plant.
The following calculation estimates the reduction in sediment deposited in the Saguling Reservoir and the benefits in terms of electricity production time at the Saguling Hydroelectric Power Plant, expressed in rupiah, with waste management at the Area of Saguling Reservoir = 5,343.
