Analysis of the participation rate in its waste management used Spearman Correlation Test. Financial feasibility analysis of Elegant Quality compost plant can be seen from the criteria of NPV (Net Present Value), Net B/C (Net Benefit/Cost), and IRR (Internal Rate of Return). Value of economic benefits by the city garbage scavengers obtained from the estimated volume of waste dauran materials obtained by scavengers multiplied by the value of selling. Primary data were collected through interviews using questionnaires and field observations. While secondary data obtained from literature studies that collect data that has become the archives for the manager, through the tracing information from the related institutions .. Community participation in district level Ciracas in waste management were categorized as high with the percentage (71.67%), this suggests a positive outlook, because the future of education levels tend to increase recycling and composting activities provide economic benefits and have a good opportunity to developed.

The majority of landfill waste in East Jakarta came from residential 5300 m³/day (78.91%) and the market with a volume of 580 m³/day (8.64%). Amount of landfill waste is served that is equal to 83.43%, the remaining 16.57% of waste is not transported. Handling waste in the form of recycling (4-3R) in East Jakarta at 354 m³/day will be reduced at least 5.27% per day from the garbage of 6716 m³/day. While handling in the form of composting for 46 m³/day will reduce at least 0.68% per day from the garbage of 6716 m³/day.

Judul: Karakteristik Anatomi Skelet Kepala Buaya senyulong (Tomistoma schlegelii).
Abstrak: Buaya sepit atau senyulong (Tomistoma schlegelii) merupakan jenis buaya asli Indonesia yang berhabitat di sungai-sungai Sumatera, Kalimantan, dan juga pedalaman Sulawesi. Salah satu ciri khas buaya senyulong adalah bentuk moncong yang runcing dan sempit, namun hingga saat ini informasi mengenai struktur skelet kepala buaya senyulong sangat terbatas. Penelitian ini bertujuan untuk mempelajari karakteristik anatomi skelet kepala buaya senyulong yang dikatikan dengan fungsi dan perilakunya. Penelitian dilakukan secara eksploratif dengan melakukan pengamatan, pencatatan, dan pengambilan gambar dari skelet kepala buaya senyulong. Skelet kepala berukuran panjang 70 cm, lebar 29 cm, dan tingggi 17 cm dengan permukaan kasar pada os nasale, os frontale, os maxilla, os mandibula, os lacrimale, os jugale. Jumlah gigi pada buaya ini sebanyak 78 buah, terdiri dari 4 buah gigi premaxila, 16 buah gigi maxila, dan 19 buah gigi mandibula. Pada regio orbitalis ditemukan dua pasang fenestrae temporales yang berkembang baik. Fenestra supratemporale merupakan lubang oval yang membentang di sepanjang os parietale. Fenestra infratemporale berbentuk segitiga dan dibatasi oleh os squamosum, os postorbitale, os jugulare, dan os quadratum. Os mandibula hewan ini mempunyai symphysis mandibularis yang panjang yaitu garis yang melintang di corpus mandibulae. Secara fungsional ukuran symphysis mandibularis berkaitan dengan adaptasi hewan terhadap diet makan.
