Old meets new in biopore campaign

The Jakarta Post, Jakarta

It's an old technique often used in Indonesia's rural areas, but the campaign for backyard biopore absorption holes (biopores) was heard for the first time in Jakarta on Saturday.

Enthusiasm ran high as experts from the Agricultural Institute of Bogor (IPB) and Erhalogy, a cosmetic brand, talked to Setu Babakan residents in Jagakarsa, South Jakarta.

The household technique, combining waste and water management, involves drilling a hole no bigger than 30 centimeters wide and 100 centimeters deep as an organic waste bin that also increases groundwater absorption.

"The old technique takes on new meaning as it can be used to mitigate flooding and take care of our waste problem," said Kamir R. Brata, professor from the landscape architecture department at IPB, who coordinates the campaign.

In Indonesia, the compost sinks began to receive more attention after February's flood which took numerous lives and caused losses of trillions of rupiah.

In April, the Bogor administration ordered more than 5,000 biopores sunk in 21 subdistricts.

As of June, Bogor had finished more then 22,000 holes. Kamir wants to expand the program to surrounding areas, including Jakarta.

According to Kamir, Jakarta planners have ignored the environment, preventing nature's underground network of roots, insects, worms and rodents from living up to potential.

Biopores return natural function to the ground when organic waste is composted, because insects and worms thrive, multiplying tiny passageways in the soil which absorb water.

"God has already given us the workers to keep floods away, now our duty is to make sure these workers don't leave."

The hole is made with a T-shaped hand drill which rotates clockwise. After the hole is made and tidied up, an effective microorganism (EM) solution is added to speed up decomposition.

All of the tools can be ordered from the landscape architecture department at IPB.

The ideal number of holes depends on the intensity of rains in the area. Adequate, however, explained Kamir, is for five small households sharing one drill to sink 25 holes in the immediate vicinity of their homes.

Dimiati, a corn farmer and producer, is among those who are not yet satisfied with the waste solution. While the holes may be able to deal with household waste, he said, he doesn't think they can handle industrial byproduct, which accumulates tons at time.

"I still don't see it as the solution to the waste problem," he said.

IPB and Erhalogy gave the four neighborhood units in Setu Babakan -- comprising 120 households -- 24 iron drills, 120 waste containers, eight drums of EM solution and ready-to-use EM and EM starter kits.

The donors plan to spend four months making sure the tools are used properly and the biopores maintained properly.

"The company is just concerned about the environment. The way we see it, the surface of the earth is like skin -- it needs pores to stay healthy, so we believe this idea is an innovative way to promote our brand," Erhalogy marketing manager Djoko Kurniawan said.
