Kelurahan Pancoran merupakan salah satu lokasi padat penduduk di Jakarta selatan. Besarnya jumlah penduduk dan keanekaragaman aktivitas di Kelurahan Pancoran berkontribusi terhadap peningkatan jumlah dan permasalahan dari timbulan sampah. Sampah organik yang berasal dari rumah tangga mendominasi timbulan sampah di Indonesia. Timbulan sampah organik di kelurahan Pancoran berpotensi untuk dikelola dengan baik. Metode Komposting menggunakan keranjang Takakura sangat tepat diperkenalkan sebagai teknologi tepat guna dalam pengolahan sampah organik. Permasalahan yang terjadi saat ini adalah partisipasi masyarakat yang masih kurang terarah dan terorganisir secara baik, masih minimnya kepudilan masyarakat terhadap permasalahan sampah. Adanya potensi sampah rumah tangga untuk diolah bahkan dapat bernilai ekonomi, namun belum maksimal diterapkan karena masih kurangnya motivasi dan wawasan masyarakat dalam mengelola sampah. Kegiatan Pelatihan Pengelolaan sampah di kelurahan Pancoran telah dilakukan yang dihadiri oleh 20 orang peserta yang terdiri dari ibu-ibu rumah tangga dari beberapa perwakilan RT di RW 04 kelurahan Pancoran Jakarta Selatan. Dengan metode penyampaian secara presentasi, praktik pembuatan keranjang Takakura, diskusi dan tanya jawab.  Pelatihan pengolahan sampah skala rumah tangga menggunakan keranjang Takakura diharapkan dapat meningkatkan keterlibatan masyarakat di Kelurahan Pancoran dalam mengelola sampah mereka, dan dapat mensosialisasikan serta memotivasi rumah tangga lain di sekitar sehingga dapat menjadi salah satu contoh kawasan yang bersih, sehat, dan bebas dari sampah.

Background: The Government of Indonesia is currently implementing its Coastal Community Economic Empowerment Program or Pemberdayaan Ekonomi Masyarakat Pesisir (PEMP) to numerous coastal communities in the island of Java, Sumatra, Sulawesi, Kalimantan and Nusa Tenggara. The program is geared to empower local coastal communities through its integrated, holistic vision, its local-based, participatory method, and its public-partnership approach. Locality is important since the program aims to induce local initiatives and retain social and economic progress within the area, taking into account its ecological carrying capacity. Method: The research is a qualitative inquiry using ethnomethodological tools and purposive, snowball sampling. The research was conducted in 2015-2016 in Cilacap, Central Java.Â Â Data analysis was conducted through tabulation, categorization, comparison, conceptualization and theorization. Results: Issues beset the governmentâ€™s PEMP program, including its utilitarian framework to coastal resource governance, its adverse incorporation of small fishermen into the fishing industries, and its unsustainable public-private partnership to promote entrepreneurial growth. Attempts to resolve those issues include ensuring that funding for the PEMP program is incorporated within the yearly provincial and regency budgets and regulations, instilling consensus building over the programâ€™s direction and activities with local communities and the private sector through the Provincial and Regency Level Peopleâ€™s Representative Council, and brokering with local communities and the private sector to achieve workable common ground should conflicts arise. Conclusion: Establishing sound intervention policies and programs require securing flexibility and adaptive management capacity through negotiations and brokering.
