JAKARTA - PLN Nusantara Power has managed to manage the remaining coal burning Fly Ash Bottom Ash (FABA) produced in the generating unit.

Throughout 2023 PLN Nusantara Power has succeeded in utilizing FABA as much as 1.6 million tons FABA from a total production of 1 million tons, of which 0.6 tons were the remainder from the previous year.

From the use of this FABA, PLN NP succeeded in establishing 4 houses made from FABA which were intended for the welfare community and the offices of Village-Owned Enterprises (BUMDes).

PLN NP President Director Ruly Firmansyah stated that FABA management is part of the company's efforts to optimize FABA for the benefit of the community.

The 2023 FABA produced by PLN NP has been very optimally utilized. By the end of December 2023, its utilization was already more than 168 percent. Of the total production of FABA of 1 million tons, the accumulated utilization reached 1.6 million tons. FABA comes from 20 PLTUs in Java, Sulawesi, Kalimantan and Sumatra," Ruly explained in his statement to the media, Wednesday, January 24.

Ruly explained that so far FABA has been used as a raw material for substitution of hardwood concrete products, roadbases, light brick, neutralizing mine acid water, fertilizers, and wave breakers.

FABA, he said, is also used as a trigger for people's economic circular livelihoods through Paving block, precast and light brick MSMEs.

"The latest of us through the Pacitan PLTU has succeeded in establishing a Habitable Residence House (Rutilahu) which we handed over to Mbah Wijiati, one of the victims of the Bantul Earthquake that occurred in June 2023", added Ruly.

PLN NP through PLTU Tanjung Awar- Awar also managed to manage FABA into 2 houses of residents. In addition, through PLTU Paiton in collaboration with the Sepuluh November Institute of Technology (ITS), 1 earthquake-resistant house called BIMA (Simple Modular Instant Building). BIMA will be used as the operational office of the Village-Owned Enterprises (BUMDes) Sumberejo Village, Probolinggo.

FABA is used for a mixture of concrete as part of the concrete structure (column, beam and foundation) consisting of cement, sand, gravel, FABA and water. Fly ash replaces 40 percent of cement, while bottom ash replaces 50 percent of the sand. In BIMA's light brick wall material, fly ash replaces 100 percent of the sand.

The use of FABA is not limited to the construction of houses alone. Through PLTU Tenaya, PLN Nusantara Power has also established a RTH Puteri Kacang Mayang Digital Read Corner, Clean Water Facilities, to the Health Center Health Building made from the use of FABA.

In other parts of the region, PLN Nusantara Power also uses FABA as a paving material, subgrade, cansteen, and wave breakers to prevent abrasion in coastal areas.
