Judul: Development of fishing operation safety frame work in the province of Central Java
Abstrak: Charachteristics of the occupational in fishing vessel are dangerous, dirty and difficult, known as “3d”. Fishing vessel safety is a complex interactions among human factors, machines and environmental. Fishing safety problems emerge when minimum one of those elements of human factor, machines or environment is misfunction. The general objective of this research is to develope frame work of fishing vessel operation safety in Central Java Province. Specific objectives of this research, are as follows: 1) identification database systems of fishing vessel accident; 2) identification of crews quality and capacity, 3) identification of the safety equipment, 4) identification of the national and international regulations on fishing vessel safety, 5) to make the alternative policies and strategies on fishing vessel safety management, to make strategies development on maritime training and education. Results of this reasearch, are: 1) to provide national database systems on fishing vessel accidents and investigations and to integrate this system database into fisheries satatistic, 2) the level of safety and navigation competencies of the skippers are still in low level, 3) fishing vessels which already equipped with the minimum safety equipment as much as 29,69%, 4) the existing regulations for seaworthiness and shipmanning of fishing vessel need to be reviewed, 5) the Fatality Accident Rate (FAR) is 113 fishermen died/missing at sea per 100.000 fisherman per year and if it is compared with the FAR of the world fishing fleet, it‘s still consider higher. The average FAR of the world is 80 fishermen per year, 6) the position of the fishing vessels accident on F-N matrix is still on the unacceptable risk level. The necessary measures to reduce accident risk of fishing vessels accident are needed. Some of the measures that we suggest, are as follows: 1) to estasblish national database systems of fishing vessel accidents and investigations and to integrate this system data base into fisheries satatistics, 2) training on navigation and safety competences (BST) for skippers and crew members, 3) increasing safety awareness for the fishing vessel stakeholders 4) crews insurance, 5) to provide standard of fishing vessel, ship manning, works in fishing, education, training and certification, 6) extended researchs are needed on development model fishing vessel safety development, B/C analisys and to make standart ship of fishing vessels less than 60 GT that suitable to be operated in southern Jawa Island waters

Judul: Fishermen work safety at fishing operation on payang in Palabuhanratu, West Java
Abstrak: The main cause of marine accidents resulting in loss of human lives is purely human error. Specifically on the capture fisheries, as many as 80 percent of marine accidents are caused by factors of human negligence (FAO, 2009). The purpose of this study is to inventory and describe all hazards and possible consequences in every aspect and stage, inventory and identify those aspects related to the management of safety of fishermen, both institutionally, existing regulations, human resources, working conditions and safety design models fishermen work at the sites. Scope of the study was limited to payang fishing activities in fishing operations in Palabuhanratu. The research was conducted in October 2011 - August 2012, in district Palabuhanratu West Java, especially in PPN Palabuhanratu. This research activity was carried out by conducting literature studies and interviews with the aim of collecting primary data in the form of direct observation and interviews/questionnaires to all the components, either directly or indirectly involved. Collection of secondary data fishery, related regulations, journals, and other related literature. Policy and institutional analysis be descriptive. The next method is the Formal Safety Assessment (FSA), the human element can be incorporated into the FSA process using human reliability analysis (HRA). HRA in this study quantitatively. To complete the picture details the development of systems analysis models to understand and make decisions related to SMK3. Activity that has a chance of failure risk was greatest in gear operating activities during setting. Consequences of accidents greatest opportunity in hauling activity. Risk control is done with the selection of a competent crew, plan fishing/sailing, designing safe work procedures, use of equipment as needed, using personal protective equipment and conditioning healthy working environment, as well as coordination among crew always do. Need to restructure relating to the management of fishing safety associated with existing policies and institutions, so that the mutually synergistic implementation. Analysis of the safety management system of the fishermen showed no systemic features and characteristics of the organization who have learning disabilities. (A) Each stakeholder tends to stand in their own point of view or interest. (B) Completion of the problems in safety management fishermen tend gradually, not structured and are regional and do not change the mindset. (C) In the safety management practices on certain aspects (control) often occurs transitional resources for the benefit of others. This transfer shows that the issue of safety management is not a priority fishermen and not something that should be addressed immediately. (D) Aimed of fishing safety management is not up to the level of implementation.

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
