Abstrak: The West Pasaman Regency, since 1990 the problems faced by the district is agricultural land conversion to the function of paddy fields into plantations palm oil. The passing of Law 41, 2009 on the Protection of Sustainable Food Farming Land (PSFFL) is expected to control the pace of agricultural land use change in particular fields. The aim of this research are: (1) to analyze and identify land use, evaluate land suitability and land area of actual and potential paddy field, (2) to analyze and identify the actual paddy fields of land that has a network of agricultural support infrastructure, (3) to analyze the projection needs of rice field at the district levels, (4) to analyze the public opinion of the main factors affecting the determination for sustainable food farming land and reserve sustainable food farming land, (5) to classify the land for the proposed as the sustainable food farming land and reserve sustainable food farming land. This research was conducted in the West Pasaman Regency began May 2012 until August 2012 using primary data and secondary data. This research used analysis and identification of land use, land suitability evaluation, extensive wetland actual and potential, having the actual wetland agri-food network infrastructure, analysis of the projected needs of the district and sub-district of paddy fields and grouping land. The results showed that land use in the West Pasaman district dominated by oil palm plantations covering an area of 100,642 ha (28.46%) of the total area of land cover, while the use of land for agriculture food such as irrigated and rainfed rice has an area of 27 231 ha (7.70%). Land suitability classes indicate that most of the West Pasaman or about 60% are in the land suitability class S which is technically very fertile for rice cultivation. The West Pasaman district has had a road network actually rice on rice fields and irrigation network has spread in almost all districts. Availability of paddy fields in the West Pasaman Regions still enough to feed themselves for 20 years to come. Physical factors namely availability of actual and potential land take precedence in determining for sustainable food farming land and reserve sustainable food farming land. The actual and potential land available in the West Pasaman district is 39,192 ha. After screening an area of 9918 ha, the actual and potential land has decreased, to 29 274 ha. The actual land area of 27,231 ha initially reduced area of 2756 ha to 24,475 ha. The potential land reduced the original 11,961 ha area of 7162 ha to 4799 ha. Three priorities of AHP/projection/land suitability, administrative boundary, and ethnic considerations might be used to identity sustainable food farming land and reserve sustainable food farming land.

Judul: Potential Availability of Forage in Oil Palm Plantations in West Pasaman Regency
Abstrak: Hijauan pakan ternak bisa didapatkan dari berbagai sumber, salah satunya adalah dari perkebunan kelapa sawit. Perkebunan kelapa sawit memiliki potensi yang sangat besar untuk pengembangan peternakan ruminansia. Tujuan penelitian ini adalah mengetahui potensi hijauan yang ada di perkebunan kelapa sawit Kabupaten Pasaman Barat. Penelitian dilaksanakan di dua lokasi yang berbeda dengan luasan lahan masing-masing 2 ha. Pengambilan sampel dilakukan secara acak terencana, setiap lokasi diambil sebanyak 30 cuplikan sampel hijaun menggunakan kuadran 100 cm x 100 cm, untuk identifikasi hijauan, menghitung produksi hijauan dan kapasitas tampung. Hasil penelitian menunjukkan terdapat 24 jenis hijauan yang bervariasi dengan proporsi hijauan yang ada meliputi rumput, legume, rumbah dan pelepah daun kelapa sawit. Produksi hijauan pakan di perkebunan kelapa sawit Pasaman Barat tahun 2020 yaitu 994 ribu ton tahun-1 dengan kapasitas tampung perkebunan kelapa sawit yaitu 436.000 ST tahun-1, sedangkan jumlah ternak yang ada adalah 22.648 ST, maka berdasarkan potensi biomassa hijauan di perkebunan sait dapat ditambah ternak sebanyak 413.352 ST., Forage fodder can be obtained from various sources, one of which is from oil palm plantations. Oil palm plantations have enormous potential for the development of ruminant livestock. The purpose of this study was to determine the potential of forage biomass in oil palm plantations in the West Pasaman Regency. The research was carried out in two different locations with a land area of 2 ha each. Sampling was carried out randomly, each location is taken as many as 30 samples of forage samples using a 100 cm x 100 cm quadrant, for forage plant species identification, forage production, and storage carrying capacity. The results showed that 24 types of potential forage plant species were identified, including grasses, legumes, rumba (other indigenouse plant species), and oil palm leaf midribs. Potential forage biomass was 994 thousand tons year-1, which is possible to supply forage with carrying capacity 436.000 animal unit year-1. This number enable additional population of cattle with 22,648 animal unit in west pasaman regency in term of forage biomass potency in soil palm plantation.
