Abstrak: SYARIF AHMAD. Community-Based Flood Disaster Risk Mitigation Strategy on the Sugi River Banks, Tarempa Village, Siantan District. Supervised by YUSMAN SYAUKAT and A. FAROBY FALATEHAN. Title of this research is "Community-Based Flood Disaster Risk Mitigation Strategy on Sugi River Banks, Tarempa Sub District, Siantan District, Anambas Islands Regency". The aim of this research is to identify disaster risk reduction efforts; Assessing community perceptions of flood disaster management and formulating community-based disaster risk reduction strategies. The research show that community empowerment programs/activities have been implemented, but not adequate due to limited human resources and lack of budget allocation. The strategies formulated in this research include: (1) Disaster Resilient Villages (DESTANA), (2) Disaster Risk Reduction Forum (PRB), and (3) Community-Based Reforestation. This research uses Analytical Hierarchy Process (AHP) method, from the results of the assessment DESTANA has the highest score: 0.715, the PRB forum scores: 0.217 and Community-based Reforestation scores: 0.068. DESTANA was chosen as the highest alternative because it accommodates a wide range of programs/activities for the preparation and implementation of community-based flood disaster mitigation strategies. The Government along with the community need to formulate organized and sustainable action plan by using local wisdom to mitigate flood disasters. Pentahelix stakeholders need to make joint efforts to rehabilitate hydrological functions in river bank and water catchment areas.

Abstrak: Flood events that occurred in Karawang included in river flooding. Flooding of the river is flooding events due to the overflow of the river water. Karawang district is an area drained by streams Citarum. Genesis flood in Karawang regency not only affects the home and road stagnant, but also have an impact on stagnancy of agricultural region. These conditions led to increased social and economic problems in farming communities in the region downstream of Karawang. This research attempts to see how the whole community of farmers who live in the area downstream doing living strategies for survival of flood event. In addition to this , this research tries to analyze the choice of action and livelihood strategies undertaken by farmers as well as its impact on life in the household. At the same time trying to conclude option better livelihood strategies in the face of extreme climatic conditions. This research uses the approach of moral theory of peasant economy as a basis for the analysis of the actions of households facing flood events. Livelihood strategies are analyzed by using the approach of Ellis (1998 ), which emphasizes on the choice of livelihood strategies in times of crisis and during normal livelihood strategies. Last analysis using the approach of decision making within the household to see the role of dominance in the household decision during a flood event or when normal. This research was conducted in the village of Sungai Buntu, Karawang District Pedes for 6 months with twice the data collection is in May to June 2013 and March to May 2014. This study used a qualitative approach to the quantitative data supported the case study method flood events that occurred in Sungai Buntu Village. Data obtained from in-depth interview process and using a simple questionnaire. This study took 30 respondents farm workers and 6 respondents landowners with key informants are local community organizations, village chiefs, village officials, and the local community. Data were analyzed using qualitative data analysis that begins with the reduction and ends with a conclusion. Increased incidence of poverty due to flooding caused by extreme climate issues and the high land conversion due to development policies that destroy natural resources and the environment so as to encourage an increase in the vulnerability of communities in flood -prone areas. Increased vulnerability of communities is an increase in poverty in society. Flood events that occurred in the village of Sungai Buntu divided into two inter alia regular flooding events with a period of one year once and flood events. Regular flood events is an event that happens once a year that have an impact on the acceleration of the decline of the growing season and harvest time. Genesis flood disaster is an event that occurred in more than a month with a high pool of more than one meter. Flood events cause various problems both social and economic problems that occur within the ii community and household. Various problems due to flood events that the community must take action to be able to survive. Action to survive referred to as

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
