RRI.CO.ID, Jakarta - South Manggarai Village in Tebet Subdistrict, South Jakarta, has launched an innovative biowash liquid made from fermented kitchen waste to enrich urban growing media. The independent initiative is expected to support the urban farming movement while also addressing the lack of fertile land in the densely populated capital.
“Biowash is the result of fermenting leftover fruit peels or fresh vegetable scraps mixed with microorganism liquid or a special starter (Promic), and it is a fast way to turn organic waste into a more useful growing medium,” said South Manggarai Village Head, Sri Nurwiyanti, in Jakarta on Wednesday, 8 July 2026.
Sri explained that the process uses one kilogram of organic waste, made up of fruit peels or fresh vegetable scraps, mixed with 200 grams of Promic starter and five liters of water, then left to ferment for three days.
Once fermented, the liquid can be used in a 1:30 ratio, meaning 1 liter of biowash is mixed with 30 liters of water. “At the moment, the production process is still being carried out at the urban village office,” she said, as quoted by Antara.
The organic waste used in the process comes from residents who bring their waste directly to the urban village office, as well as from food stalls around the area, to be processed into biowash there.
Sri added that socialization about biowash has also been carried out at every meeting, so residents and Family Welfare Empowerment (PKK) cadres are expected to be able to make it themselves at home.
“Going forward, we hope this method will allow us to process organic waste into growing media in our area more quickly. It will also be easier to use for plants, and in the future, the results of this method may even have economic value for the community,” she said. ***
