Currently in Cisauk area, there are still a lot of trashes lying on the streets, ditches, rivers, and other public places. The government has encouraged all citizens to sort out garbage and process organic waste into compost. However, not many people comply with this encouragement due to their ignorance or lack of knowledge about practical composting methods. This study aimed to improve social awareness in managing and processing organic domestic waste into compost using Takakura home composting method, which is easy, inexpensive, and odorless. Moreover, different home-made compost starters with different mixed microbial inoculants were compared. The study included microbial inoculant preparation, home-made compost starter production from rice husk and rice bran, and compost production in Takakura basket. The methods were taught through a series of workshop in Bermis Serpong Asri Residence, Cisauk, Tangerang. Through this effort, the problem of domestic organic waste was expected to be overcome. Moreover, the product of Takakura home composting can be used as plant and soil fertilizer, or even sold to increase family income.

Waste that is not managed well may potentially cause diseases and negatively affect the quality of life. Rusunawa Muara Baru, Jakarta, is one of our partner communities that need continuous training in all aspects, including waste management. Therefore, the present community service program was carried out to educate the residents of Rusunawa Muara Baru on the importance of sorting waste and how to process household organic waste into liquid organic fertilizer and bokashi compost. The program was conducted twice in two weeks. At the first meeting, an introductory questionnaire was distributed, an interactive discussion was performed, and a fertilizer production workshop using simple composters was initiated. Two weeks later, the composting results were evaluated, and the participants filled out the evaluation questionnaire. Approximately 83% of the participants agreed to sort household waste after the program was completed, which showed the participants' increasing awareness in waste processing. The liquid biofertilizer produced was used for planting vegetable seeds even though it still had a foul odour. The quality of the compost produced, however, was still below expectations. We suggest that in the future, education and workshops on simple household-scale composting methods capable of producing good quality liquid organic fertilizer and compost without odour should be conducted.

Waste disposal and clean water management are some of the common social issues arising in densely populated settlements, including Muara Baru flats, Jakarta. Some programs have been carried out to overcome these two issues in Muara Baru, such as the construction of a Rain Water Harvesting (RWH) facility and the provision of Trash Banks. Nevertheless, adequate support for the residents is still needed to boost their awareness of proper clean water management and waste disposal and to encourage the formation of urban agriculture, which is expected to elevate their living standards. Therefore, a community empowerment program in Muara Baru was developed, consisting of three sections: education on clean water management, compost making training, and urban farming. The success of this program was then measured using questionnaires and focus group discussions. A majority of residents responded positively to the program and were willing to actively participate by preparing the land, making compost, planting seeds, or caring for the harvest. There were indeed some obstacles hampering the program's success, such as lack of commitment from the local community, climate change, water availability, and arable land availability. To overcome these barriers and to promote the program’s sustainability, some suggestions are to be proposed, including proper selections of plant types and provision of support and motivation for the local community.
