Sumbawa Barat funds a waste bank in every village, and budgets for running it

An allocation with three parts

West Sumbawa regency, known as KSB, is putting Rp150 million into every village for waste management through the revised 2026 village budget. The allocation sits inside a larger financial assistance package of Rp500 million per village.

The money divides three ways. Rp100 million goes to physical construction of a waste bank in villages that do not yet have one. Rp25 million is working capital for running the operation. Rp25 million covers operating costs. Villages that already hold a TPS 3R facility are directed to optimise what they have rather than build something new, and reporting on the programme indicates most villages are constructing new waste banks while a smaller group revitalises existing TPS 3R sites.

Regent H. Amar Nurmansyah has stated the split directly, describing Rp100 million for building waste banks and Rp25 million each for management and operations. Village heads are the focal point for delivery.

The regency is targeting at least 30 percent of waste generation filtered out before it moves to further processing or to the landfill, under a broader goal it calls KSB Bersih 2027.

Why the split matters more than the total

Rp150 million is not a large sum, and the total is not the interesting part of this policy. The structure is.

The most common failure mode in Indonesian village level waste programmes is a fully funded building with no funded operation. A capital grant constructs a waste bank or a TPS 3R shed. Nobody budgets for the person who staffs it, the fuel for the collection vehicle, the float needed to buy material from residents, or the maintenance on the shredder. Within a year the building is locked and the programme is recorded as complete.

KSB has separated the three cost types and named an amount for each. Working capital is the part most often missed. A waste bank works by buying sorted material from households and selling it on at a margin, which means it needs cash on hand before it has revenue. Without a float, the bank can only accept deposits it cannot pay for, and household participation collapses at the first unpaid deposit.

Allocating Rp25 million as a float and a further Rp25 million for running costs converts a construction grant into a functioning small business. That is a design choice other districts can copy at no additional cost, because it is a matter of how a budget line is written rather than how large it is.

The regent has described the intended end state as a savings pattern, a waste bank that works the way a bank holds deposits, with material handed over by residents recorded as a balance the household can draw on. That framing matters for participation. A household that treats separation as a cleanliness obligation complies while someone is watching. A household that treats separation as a deposit into its own account has a reason to continue when nobody is. The savings pattern only works if the float exists, which makes the budget choice and the behavioural choice the same decision.

Karang Taruna and TBA agents as the operating layer

The regency has been specific about who runs these facilities. Karang Taruna, the village youth organisations, serve as operational managers and receive incentive payments for the role, coordinated through the social welfare side of the administration.

We budget 150 million rupiah per village to activate waste banks and TPS 3R. With social welfare coordination, youth leaders receive incentive payments as operational managers.

Alongside them, women serving as TBA agents use existing community networks to promote household separation of organic and non organic material. Deputy Regent Hj. Hanipah has emphasised household discipline as the foundation the rest of the system rests on.

Using two existing village structures rather than creating a new body is sensible. Karang Taruna already has a membership, a meeting rhythm and a recognised position in village life. TBA agents already visit households. Neither needs to be established, funded into existence, or explained to residents. The programme attaches a paid function to organisations that already exist, which is considerably faster than building an institution.

The regency has also moved on collection hardware, with 38 community groups in Taliwang subdistrict receiving three wheeled waste collection motorcycles.

The facilities the villages feed

Village waste banks only reduce landfill volume if what they collect has somewhere to go. KSB is building the next tier in parallel, with three integrated waste processing facilities planned to begin construction in 2026, at Batu Putih, Benete and Senayan, intended to serve all subdistricts.

That sequencing is the right way round. Village level collection improves material quality and captures the recyclable fraction. The TPST tier handles the volume and the processing that a village cannot. A regency that builds only the top tier ends up with a facility receiving mixed waste, and one that builds only the bottom tier ends up with waste banks holding material they cannot move.

The regency has paired the infrastructure with education, running an Expo Karya under the theme of turning waste into a blessing during World Environment Day and the regency's 23rd anniversary, involving 14 groups made up of seven schools and seven waste bank communities. Nurmansyah has argued that sorting habits need to form during school years, and the regency is working the theme into local curriculum material.

Sirkularium's view for government and public institutions

Three points for districts and provinces.

First, on budget line design. The three way split between construction, working capital and operating cost is the most transferable element here, and we would encourage other districts to adopt the structure explicitly in their village fund guidance. A waste bank is a trading operation. Funding its building without funding its float is the single most reliable way to produce a facility that does not operate.

Second, on delivery through existing structures. Attaching paid operational roles to Karang Taruna and to TBA agents avoids the cost and delay of creating new village institutions, and it puts income into the village rather than into an external contractor. Districts should check whether the incentive payments are large enough to hold people in the role through a second and third year, because the attrition point in volunteer led schemes is usually not the launch.

Third, on tier alignment. Districts planning a TPST should confirm that village level collection will be operating before the facility commissions, and districts funding village waste banks should confirm there is an offtaker for what those banks accumulate. KSB is building both at once, which is the harder sequencing to manage but the one that avoids a stranded asset at either end.

What to watch next: how many villages have a functioning waste bank operating by the end of 2026 rather than a completed building, whether the Rp25 million float is drawn down and revolves as intended, construction progress at Batu Putih, Benete and Senayan, and whether the 30 percent diversion target is measured at the landfill weighbridge or estimated at village level.

KSB has budgeted for the running of the thing, not only the building of it. Sirkularium will continue following whether that distinction shows up in the results.
