Going back to last year, the accumulated waste has not yet been fully transported to the Kebon Kongok Final Disposal Site (TPA). Only about 300 tons had been transported from the Sandubaya Integrated Waste Processing Site (TPST) to TPA Kebon Kongok.

“The remaining 350 tons of waste have yet to be collected,” said Vidi Partisan Gumanjaya, Head of the Waste Management Division at the Mataram City Environmental Agency.

Guess what, other problems arise as of this week.

Now, the smell from Sandubaya Integrated Waste Processing Site has reached the main road.  This problem is caused by the accumulated waste that hasn’t been picked up yet. 

Head of the Environmental Agency of Mataram City, Nizar Denny Cahyadi asked the people to understand the situation.  There has been a limitation of waste disposal to Kebon Kongok Final Disposal Site (TPA) and it caused the TPS Sandubaya to reach full capacity. 

“Yes, we need to be patient for now. Residents also need to understand the situation, as this is an emergency and there is currently no place to dispose of the waste,” he said on Tuesday morning (April 29).

He admitted, the problem of the waste at TPS Sandubaya can not be held anymore. 

Right now, the waste has reached 1000 tons.

With this condition, the Mataram Municipal Government wished that there was a solution to the problem(?)

While waiting for the recovery of the Kebon Kongok Final Disposal Site (TPA), the government is planning to prepare a land for disposal. 

But right now, the land has not got the permission from the central government. 

“Tomorrow (Wednesday), we will hold a meeting with various ministries—Public Works and Housing, Environment, and others. If the discussion is finalized tomorrow, we should be able to start disposing of waste at the new designated site this week,” he said.

The total of the new designated disposal site is up to 60 acres, in Lembar district. 

The government did not mention specifically about the lease of the site. 

The lease for the site will be financed by the three administrations, which are the Province of West Nusa Tenggara (NTB), the City of Mataram, and West Lombok Regency.

“The rental cost will be split into three parts. Don’t ask about the exact amount—it will be covered by us (Mataram City), West Lombok, and the Province of West Nusa Tenggara (NTB),” Denny emphasized.

The designated site will be used in a temporary manner by two district administrations for the island disposal. 

This temporary disposal site will be operating until there is a permanent solution. 

And, it hoped, that the government will give the permission for a new disposal site. 

The government has already developed a plan to address this issue. TPST Sandubaya serves as both a solution to plastic waste and a new source of local revenue for Mataram City, as outlined in the following key points.

Modern TPST Sandubaya Operational

Mataram City’s new Integrated Waste Processing Site (TPST) in Sandubaya, funded by Rp19.9 billion from the central government, began trial operations in June 2024.

High Plastic Waste Volume 

The TPST processes 40–46 tons of waste daily, with plastic making up about 61%—more than organic waste.

Plastic Waste Turned into Paving Blocks

The facility produces 100–200 plastic-based paving blocks per day, with over 5,000 blocks made so far and used for local infrastructure.

New Revenue Streams from Waste

Mataram plans to commercialize plastic waste and maggot farming, generating local income and potentially earning Rp4.5 million per ton of plastic.

Significant Reduction in Final Waste

Only 5–6 tons of residue are sent to the landfill, thanks to efficient processing using modern technology.
