Judul: Potential Hazards in the Loading and Unloading  Activities of Cast Net Ships at Muara Angke Fisheries Port, Jakarta
Abstrak: Kapal Jala Jatuh merupakan kapal cumi terbanyak kedua yang ada di PPN Muara Angke. Aktivitas bongkar merupakan aktivitas utama yang dilakukan setelah kapal berlabuh di dermaga. Aktivitas ini terindikasi memiliki potensi kecelakaan kerja, sehingga perlu adanya identifikasi potensi bahaya pada aktivitas bongkar muat ini. Penelitian ini bertujuan untuk mendeskripsikan aktivitas kegiatan bongkar muat Kapal Jala Jatuh di PPN Muara Angke, mengidentifikasi potensi bahaya pada kegiatan bongkar muat, serta memberikan rekomendasi dan mitigasi untuk meminimumkan risiko kecelakaan kerja pada kegiatan bongkar muat Kapal Jala Jatuh. Metode yang digunakan dalam penelitian ini adalah observasi dan wawancara kepada kapten, ABK dan buruh angkut. Analisis yang digunakan berupa analisis deskriptif, analisis Hierarchy Task Analysis (HTA), dan metode Job Safety analysis (JSA). Hasil penelitian menunjukkan bahwa terdapat 71 aktivitas pada kegiatan bongkar muat. Terdapat 8 (11%) aktivitas dikategorikan tidak berbahaya, 40 (56%) aktivitas dikategorikan bahaya ringan, 19 (27%) aktivitas dikategorikan bahaya menengah, 0 (0%) aktivitas dikategorikan bahaya berat, dan 4 (6%) aktivitas dikategorikan bahaya fatal. Perlu adanya perhatian mengenai keselamatan kerja pada aktivitas bongkar muat seperti kelengkapan alat pelindung diri (APD) terutama pada saat aktivitas bongkar muat, dan juga pengemudi yang bersertifikat guna mencegah terjadinya kecelakaan yang bersifat fatal., Kapal Jala Jatuh is the second most squid fishing vessel at Muara Angke Fisheries Port. Unloading is the main activity conducted after the vessel docks at the pier. This activity is suspected to have the potential for work accidents, thus requiring the identification of potential hazards in this loading and unloading activity. This study aims to describe the loading and unloading activities of Kapal Jala Jatuh at PPN Muara Angke, identify potential hazards in loading and unloading activities, and provide recommendations and mitigation to minimize the risk of work accidents in the loading and unloading activities of Kapal Jala Jatuh. The methods used in this research are observation and interviews with the captain, crew members, and cargo handlers. The analysis includes descriptive analysis, Hierarchy Task Analysis (HTA), and Job Safety Analysis (JSA) methods. The research findings indicate that are 71 activities involved in the unloading process. Among these, 8 (11%) activities are categorized as non-hazardous, 40 (56%) activities as mild hazards, 19 (27%) activities as moderate hazards, 0 (0%) activities as severe hazards, and 4 (6%) activities as fatal hazards. Attention should be given to occupational safety during the unloading activities, such as ensuring the availability of personal protective equipment (PPE), especially during the unloading process, and having certified drivers to prevent fatal 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.
