Abstrak: Urban settements will certainly affect the physical improvement of buildings and the economy. On the one hand the economic sector will increasingly attarct the attention of investors and migrants, on the other hand the physical development of cities ten tend to have a negative impact b by the loss of a number of catchman areas and declining function of the environment. Sungai Raya region other than the status of the Capital District of Kubu Raya, also acts as a Hinterland of Pontianak City that targeted housing needs Progress in the development f Sungai Raya enough at attention because given characteristic peatland that covers most of the Sungai Raya area.

Judul: Model pengelolaan lahan rawa lebak berbasis sumberdaya lokal untuk pengembangan  Usahatani berkelanjutan  (studi kasus di Kecamatan Sungai Raya dan  Sungai Ambawang, Kabupaten Kubu Raya - Kalimantan Barat)
Abstrak: The exploitation of swamp land is still limited when compared to the cultivation of dry land or irrigated land. Some of the factors that make the exploitation of swamp area far from expectation and its yields not maximum, for example 1) the wrong perception of farmers that the farming they are doing now has given high income, 2) a lack of capital, 3) low technological access, 4) characteristics of farmer‘s subsistence, and 5) tradition-based farming. This study was aimed to formulate a resources-based swamp land development model to increase land productivity and farmer Income. This research was conducted in the Sub-District of Sungai Ambangah in the District of Sungai Raya, and the Sub-District of Pasak Piang in the District of Sungai Ambawang, in the Regency of Kubu Raya, West Kalimantan Province. The analysis of each crop cultivated in both Sungai Ambangah and Pasak Piang gave the following results respectively for both areas; (1) rice with the R/C ratio of 3,30 and 4,80; (2) rubber with B/C ratio of 1,23 and 24,35; and (3) palm with the B/C ratio of 1,52. These results, if linked to the value of Appropriate Living Needs (ALN) and the minimum land area (ML) that must be fulfilled, indicate that the farmers in Sungai Ambangah could reach only 26,92% of ALN and require a minimum land of about 3,15 hectares; whereas the farmers of Pasak Piang could meet 34,53% of ALN and need a minimum land of approximately 2,54 hectares. Further, the sustainability status for the five dimensions in the existing condition of Sungai Ambangah obtained the index value of 54,82% or the category of sustainable enough for the institutional dimension, while the other four dimensions got the value of less than 50,00%, or categorized as less sustainable. As for the village of Pasak Piang, it got the index value of 52,19% or the category of sustainable enough also for the institutional dimension, whereas the other four dimensions obtained the value of less than 50,00% or considered less sustainable. The model formulated from the results of this study is based on the available local resources in both research sites, a model of sustainable farm development on swamp lands (UTLRL). Conceptually, this is also called an integrated farming model, that is, by integrating crops and livestock. The recommended policies formulated from the results of this study include: (1) the pattern of farming and increased cropping index, (2) maintenance of livestock, (3) the provision of farm capital, (4) the availability of micro finance institutions, (5) the active role of agricultural extension agencies, (6) farmers and farmer groups, (7) support from research institutions and higher education, and (8) post-harvest management and marketing.
