Abstrak: Sumbawa district is one of nine regencylmunicipality in West Nusa Tenggara Province which has potential natural research to support safety food now and the future. Base on sentral statistic bord (2005) agricultural sector was the bigest contribution for national food stock. Foverty in Sumbawa , district was caused by economic, sosial, cultural and institution aspect. This research are focused 1) To identify food stock institution society characteristic in Sumbawa district. 2) To identify factors wich can influence the role of comunity food stock Institution to increase safety food in Sumbawa district. 3). Identify role of "comunity food stock institution from yurisdiction, boundries role of representative To increase safety food in Sumbawa district. 4). Identify the strategy of comunity food stock to increse safety food in Sumbawa district. The Method of analysis 1). Logistic Regresion Analysis. 2). Descriptif Analysis. 3) SWOT and Analytical Hierarchy Proses (AHP) Analysis. Characteristic analysis shows that age's members of food stcok in research area are 20 up to 50 years old with revenue revolve Rp. 500.000 up to 1000.000. The higest members education degree are elementary school. 0,5 up to 1 Ha area tre own property rim where this activitie is prime revenue. Food stock capacity, price stability and market demand are revolve under target. While the supervisor support very significant in food stock developing. Regresion analysis shows that ages, food access, property rigth and supervisor support are influences society to food stock institution in developing food tenacity factors. Developing of food stock institution society strategy wich enhance food tenacity are food tenacity system developing, human resources developing, infrastructure developing, agribusiness system developing and partnership developing.

Judul: Analisis dampak interaksi pertambangan dan perikanan terhadap kesejahteraan masyarakat nelayan di Kabupaten Sumbawa Barat
Abstrak: District of Sumbawa Barat is administratively separated from Sumbawa district, NTB Province. The existence of mining company, PT. Newmont Nusa Tenggara (PT.NNT), is expected can increase the welfare especially for the fisherman society and Sumbawa Barat societies in general. The objectives of this research were analyzing the impact of fishery and mining interaction to fisherman society welfare and formulate the strategy for increasing fisherman society welfare. Data analysis was conducted descriptively, bioeconomic analysis, consumer and producer surplus analysis, and t-test statistic. Results of the research show that the existence of PT. NNT doesn’t give welfare change for local fisherman society, eventhough for the villages which close with the area of mining activities there was the increasing of income amount of IDR 282.523.496,-. The increasing of income is caused by the increasing of fisheries commodity price which caused by the decreasing number of fisherman catching. Whereas the villages which far from mining activities face the decreasing of income amount of IDR 1.289.351.440,- after the existence of PT. NNT. The existence of PT. NNT cause the increasing of catching fishery commodity price amounting of IDR 15,03,- for the villages which close with area of mining activities and amounting of IDR 35,33,- for the villages which far from area of mining activities. This condition cause the decreasing of society’s purchasing power. Secondly, the fishery policy strategies for increasing the local fisherman welfare are a) developing catch fishery, b) developing quality of fishery production, c) developing hatchery, d) developing sea cultivation and e) developing fish pond cultivation.

Judul: Invers Drazin dari Matriks Toeplitz Singular
Abstrak: Matriks Toeplitz adalah matriks yang setiap unsur pada diagonal utama bernilai sama dan setiap unsur pada subdiagonal yang bersesuaian dengan diagonal utama juga bernilai sama. Matriks singular adalah matriks yang tidak bisa ditentukan inversnya. Akan tetapi, dapat diupayakan untuk ditentukan inversnya menggunakan invers matriks yang diperumum. Invers Drazin merupakan salah satu jenis invers matriks yang diperumum. Pada karya ilmiah ini ditentukan invers Drazin dari matriks Toeplitz singular dengan menggunakan metode Leverrier Faddeev. Kemudian, ditentukan invers Drazin dari matriks Toeplitz singular yang direpresentasikan sebagai penjumlahan segitiga bawah dan segitiga atas matriks Toeplitz berdasar pada teorema Gohberg dan Semencul., Toeplitz matrix is a matrix in with element on the main diagonal has the same value and on the subdiagonal corresponding to the main diagonal also has the same value. Singular matrix is a matrix that has no inverse. However, it can be attempted to determine the inverse using a generalized inverse matrix. Inverse Drazin is a type of generalized matrix inverse. This paper discussed the inverse Drazin for a singular Toeplitz matrix using the Leverrier Faddeev method. Then, the Drazin inverse of the singular Toeplitz matrix which is represented as a sum of products of lower and upper triangular Toeplitz matrix based on Gohberg and Semencul theorem.
