WWF-Indonesia has committed to reducing plastic waste in the Ciliwung River. The Mulung Ciliwung activity was again carried out with HSBC-Indonesia Volunteers and collaborated with the Srengseng Sawah River Friends Community and Dharmapala Akademi Pimpinan Perusahaan (APP). The Mulung Ciliwung activity this time invited Bank Sampah Sejahtera from Bogor City, to share knowledge about better waste management at the household scale. This activity was held on Saturday, July 27, 2019 at the Ciliwung River Srengseng Sawah Segment, precisely at Saung Bambon Riverside. This activity was special because it coincided with the commemoration of National River Day, which is celebrated annually on July 27.

To further increase public awareness of the importance of reducing plastic waste at the household scale, this Mulung Ciliwung activity invited Bank Sampah Sejahtera. Representatives from Bank Sampah Sejahtera explained what a waste bank is, how to join and dispose of waste to waste banks, and invited participants to manage waste properly and not reuse unused items. This training is given so that no waste is wasted on a household scale. Not only that, Bank Sampah Sejahtera also showed the results of work from unused items such as tote bags, lunch bags, backpacks and pouches made from plastic packaging to foot mats from sheets that are no longer used.

The participants of the activity came from various circles, namely HSBC-Indonesia volunteers, Panda Mobile volunteers, BPDAS Ciliwung, Sahabat Sungai Srengseng Sawah community, Dharmapala APP, Laskaru community, and other communities to local residents. All participants were very enthusiastic about Mulung Ciliwung and eco-brick making activities which were carried out simultaneously. This activity also collaborated with Jagakarsa Sub-district who helped take care of the transportation of waste from Mulung Ciliwung. The action carried out by the volunteers succeeded in collecting 62 sacks of waste weighing around 1,550 kg (1.5 tons) of waste with the dominant plastic waste. This activity is expected to raise awareness for the participants involved and the surrounding residents who participated in this activity.

Conservation Discussion as a closing activity of Mulung Ciliwung was also conducted and presented Sandiaga Uno as an environmental activist, Agus Haryanto as Site Ciliwung Program Manager, Asdat as Chairman of Sahabat Sungai Srengseng Sawah, Solihin as one of the rails of Sahabat Sungai, Rezza representative of Laskar Krukut Luhur (Laskaru) which was moderated by Ari from Kedai Pena. The theme of the Conservation Discussion this time discussed the current state of Ciliwung and hopes for the Ciliwung River in the future. Sandiaga Uno regretted the current state of the Ciliwung River, "the Ciliwung River used to be the center of civilization which now seems to be the backyard of today's society," he concluded.

Agus Haryanto as Site Ciliwung Program Manager hopes that in the future there will be no more Mulung Ciliwung activities because people are already aware not to throw garbage into the river so that the Ciliwung River is free from garbage. Together we can realize this hope, not only through Mulung Ciliwung activities but also through our own actions by reducing the use of plastic and being wiser in managing daily waste.
