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: Peralatan Keselamatan Kerja pada Perahu Slerek di PPN Pengambengan, Kabupaten Jembrana, Bali
Abstrak: Fishing is one of the most dangerous activities in the world. About 80% of ship accidents occur due to human error. The availability and proper use of safety equipment can minimize the risk. This study aims to identify the suitability of safety equipment used on Slerek boat in PPN Pengambengan, Bali accordance with international and national standards, and describes the role of relevant institutions in order to increase the fishermen safety. Surveys and direct observation methods were used in this study. Aspects of the study were the types of safety equipment, numbers of safety equipment, and the suitability of equipment which must be taken. The lack of equipment and awareness about safety, and do not comply with the national standards for boat less than 24 meters length will directly affect the fishermen safety. The lack of regulations on small boat safety showed that the fishermen safety in fishing activities in Indonesia have not been considered and there is no clear policy from local and central government

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
