Judul: Potential Risks of Fisherman’s of Handline Ship Based in Cilacap Ocean Fishing Port
Abstrak: Banyaknya peluang terjadinya kecelakaan pada kapal handline khususnya di kolam pelabuhan maka perlu ditentukan tingkatan bahaya. Tingkatan bahaya tersebut dapat mempermudah menentukan skala prioritas antisipasi yang harus dilakukan. Penelitian ini bertujuan menentukan potensi risiko dan jenis kecelakaan kerja serta memastikan kelengkapan alat keselamatan kerja pada kapal handline di PPS Cilacap. Pengambilan sampel menggunakan metode purposive sampling, serta pengolahan data menggunakan tabulasi nilai dan analisis deskriptif. Hasil penelitian menunjukkan pengelompokan matriks risiko pada aktivitas kapal menuju bongkar muat kedalam lima kategori. Kategori sangat tinggi terdiri dari 10 risiko, kategori tinggi 5 risiko, kategori sedang 2 risiko, kategori rendah 3 risiko, dan kategori sangat rendah 0 risiko. Upaya untuk mengurangi terjadinya risiko kecelakaan kapal ialah melengkapi kebutuhan dan memakai Alat Pelindung Diri (APD). Sarana dan prasarana yang telah diberikan oleh pihak dinas PPS Cilacap berupa life jacket dan pelampung bulat di setiap kapal. Ketersediaan APD tidak dipergunakan dengan baik sehingga perlu adanya penyuluhan dan pengawasan mengenai kedisiplinan nelayan terhadap penggunaan APD yang menjadi upaya mengurangi risiko kecelakaan kapal yang terjadi., So many chances accidents of the handline ship especially the fishing port pool need to be determined a danger level. There is a level of danger can make it easier to determine priority scale of anticipation that must be done. The purpose of this research to determine potensial risk and type of work accident as well as evaluate completeness safety tools on the handline ship in PPS Cilacap. Data collection was used purposive sampling method. Data processing was used tabulation of values and descriptive analysis. The result of the research showed the grouped risk matrix into five groups, that is low category, medium, and high. The low category have two risks, the extreme category have 10 risks, the high category have 5 risks, the medium category have 2 risks, the low category have 3 risks, and very low category 0 risks. Effort to reduce the chances of accidents on the ship is collect and to wear safety tools (APD). Facilities and infrastructure that has been given by PPS Cilacap is life jacket and float in every ships. Availability APD not used properly so there is a need for counseling and supervisi about the discipline of fishermen to used safety tools which is an effort to reduce the risk of the ship accidents.

Judul: Potensi Kecelakaan Kerja Pada Kapal Angkut dan Alat Tangkap Bagan Apung di PPN Palabuhanratu, Jawa Barat
Abstrak: The study were aimed to describe the activities of ship carrier and bagan apung (lift net) in Palabuhanratu bay, to identify the potential hazard or risk during operating of the bagan apung in Palabuhanratu, and to identify the fishermen knowledge in working safety and the role of engaged institutions to fishermen safety. Primary and secondary data were collected in this research. Primary data were obtained by interview through questionnaire. Secondary data were obtained through literature study concerning fishermen safety occupational. Descriptive analysis was used to describe the activities of pre operation, operation, and postoperation processes of the bagan apung. Detail description included of the transportation ship unit, the fishing unit and the fishing activity on the bagan apung fishery. Job Safety Analisys (JSA) was used to examine the working method and the potential hazard at every step of the ship carrier and the bagan apung fishery activity. The result showed that, (1) based on Job Safety Analisys the risk arising were categorized into 3 of accident which were not severe (88%), severe (12%) and very severe (0%); (2) The fishermen having knowledge were categorized as good enough regarding occupational safety and procedures work on a ship. However, lack of awareness of the relevant agencies and fishermen in the management and implementation of work safety procedures in PPN Palabuhanratu had not been implemented properly.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
