Abstrak: National Spatial Data Infrastructure (NSDI) is a tool to facilitate in spatial data accessibility. One of NSDI applications is to inform forest fire vulnerability level. The information is used to prevent and analyze forest and land fire occurrence. The research project was conducted in Kabupaten Sanggau, West Kalimantan Province. Primary data was obtained from interview and questioner method by focus group discussion (FGD) and participatory rural appraisal (PRA). Secondary data was collected from various institution such as geology, soil type, slope, forest status and land use. The data was analyzed using physical, social and economical approach. Institutional capacity analysis covers human resource indicator, financial sustainability, service quality, external relation, operational management and regulation. Priority analysis in developing land and fire control system employed expert judgment with AWOT method which is an integreated analysis between analytical hierarchy process (AHP) and strength, weaknesses, opportunities, threats (SWOT). NSDI application was conducted by developing five components of national spatial data infrastructure consisting of dataset, network, accessibility, human resource and guideline. Land and forest fire data set for Kabupaten Sanggau were satellite image, toponim, land tenure, administrative region, forest area, land classification, water stream and water body, geology, climate, census area and statistical data, land use and land transportation. The levels of forest and land fire vulnerability were not vulnerable (24.64%), less vulnerable (31.10%), rather vulnerable (22.64%), vulnerable (11.50%) and very vulnerable (2.74%). The assessment NSDI for controlling forest and land fire in kabupaten level cover prevention, extinguisher, and post fire extinguishing. The prevention was emphasized in increasing the level of awareness on forest and land fire. Fire extinguishing was stressed on human resource and equipment empowerment; however post fire extinguishing was emphasized in law enforcement and rehabilitation.

Abstrak: KBDI could be used as a tool for early fire detection as it is capable of providing daily fire danger information. However, KBDI is not a good indicator of fire danger for region with climate and soil conditions different from Florida, USA where it was firstly developed. This study aimed to: (a) determine the optimum model parameters of KBDI for SBAWI, South Sumatra, (b) develop FDRS information systems based on Geographic Information System, and (c) apply KBDI model for other locations in the SBAWI. Several data were observed during period of 1 April 2009 – 11 May 2010 including rainfall, air temperature, water table depth, and soil water content in hourly basis. The data were used to obtain new, optimum KBDI parameter values for wetland in the region through optimization process. The process was done using Solver to obtain minimum of root mean square error (RMSE) between measured dryness index and KBDI calculation. The process produced several equations for calculating KBDI in the region. Water table depth was very critical for forest fire as it influences soil water content in upper soil layer. By maintaining water table depth at least 0,659 m, the fire danger in the region would be reduced. The results showed that if water table depth was more than 0.659 m, the KBDI would increase rapidly. The study developed FDRS information system that provided several facilities among others for: (a) calculating KBDI at other stations in the region, (b) providing information about spatial distribution of fire danger at 1 km resolution, (c) updating daily observed data, and (d) providing information of daily charts of rainfall, KBDI, air temperature and water table depth. Overall the FDRS information system was able to detect fire danger level throughout the SBAWI region.

Judul: Penentuan Nilai Eigen dan Vektor Eigen dari Matriks Tridiagonal 2-Toeplitz dengan Pendekatan Polinomial Chebyshev
Abstrak: The eigenvalues and eigenvectors of a matrix can be determined by finding its characteristic polynomials. The characteristic polynomials of a tridiagonal 2-Toeplitz matrix is shown to be closely connected to polynomials which satisfy the Chebyshev recurrence relationship. If the order of the matrix is odd, then the eigenvalues are found explicitly in terms of the Chebyshev zeros and the eigenvectors are found in terms of the polynomials satisfying the recurrence relationship. For even ordered matrices, the situation is more complicated. The problem in these cases is that although the Chebyshev recurrence formula is still applied, its initial values are not generating Chebyshev polynomials
