Action Scale	Province
Themes & Indicators	Ecosystem The water balance (water quantity ) of water related ecosystem, including groundwater dependent, is monitored and maintained. Measures that make hydrological alteration more sustainable and promote riverine connectivity are implemented People Wastewater from domestic (household) activities is safely treated, recycling is increased and safely reused. Economic and Development Pollution load management and circular economy is enhanced Disaster Risk Reduction and Emergency Response The risks of water-related disasters are addressed through integrated plans and strategies, monitoring systems and preparedness Investment in water related disaster security measures, such as nature-based solutions and infrastructure, to reduce damage and protect from the impacts of climate change is increased Cross Cutting Institutional setting for water security is supported with clear role and sufficient capacity, and also able to effectively collaborate and coordinate. A collaboration mechanism for public, community and multi-stakeholder participation in water resources development, management and decision making that addresses inequalities is established.

Description	DKI Jakarta Province is one of the areas that often experiences floods, which are often caused by geographical factors through a river water overflow. Urbanization and population growth have triggered the rapid development of settlements, including informal housing along the banks of the rivers, especially in the downstream areas with dense populations. Between 1981–1999, 14,860 hectares of the watershed area turned into residential areas. The existence of new residential areas, along with the increase in population, is followed by an increase in activity and waste production. A report from the Ministry of Environment and Forestry (2012) states that around 80 percent of the water in the Ciliwung River is polluted by domestic waste. This domestic waste is thought to come from settlements on the riverbanks. The existence of waste in the watershed area and the river flow will hurt the environment and human health, especially if there is a flood or river overflow. Through the identification of the type and number of waste in the river streams and riverbanks, it is hoped that the mitigation process can be carried out more precisely and easily. Aims and Objectives This study aims to carry out an identification study in the streams and banks of the rivers in DKI Jakarta to determine the amount and composition of domestic waste in the river area. This is done to see the correlation between the activity of disposing waste in the river by the community on the amount of river waste generation and how it contributes to the amount of waste disposed of in Bantargebang Landfill. In addition to identifying river waste generation and composition, the results of this study are expected to provide support for the local government and stakeholders in dealing with river waste problems in DKI Jakarta. To support this need, the process of data collecting will be done through a series of interviews, primary data, and secondary data collection that will be collected from any relevant stakeholders and local communities to broaden the understanding of conducting the study and answering the study objectives. Research Scope Location: Kampung Melayu subdistrict, Pasar Minggu subdistrict, Manggarai Watergate, DKI Jakarta; and Bantargebang Landfill Types of analysis: waste generation analysis, waste composition analysis Time frame: 15-24 August 2023 Key Findings Analysis on waste generation collected from the river and riverside in Kampung Melayu and Pasar Minggu subdistrict indicates the practice of open dumping of domestic trash to the rivers by local residents. The various waste blockages in the Kali Baru Barat River resulted in the collection of approximately 184.77 kilograms of waste over the course of 20-23 hours. Analysis on waste composition collected from water bodies in DKI Jakarta yielded varying results. Over the two-day sampling period, about 28 types of waste was segregated. Based on the calculation, organic waste was the most prevalent type of waste generated, along with plastic waste and residue.
