Judul: Identifikasi Keselamatan Kerja Nelayan Di PPI Batukaras Kabupaten Pangandaran Provinsi Jawa Barat
Abstrak: Aktivitas nelayan di laut memiliki risiko yang tinggi karena kapal penangkap ikan beroperasi mulai dari perairan yang tenang hingga perairan dengan gelombang yang sangat tinggi. Masalah keselamatan kerja di laut dan keselamatan kapal untuk saat ini tidak hanya menjadi perhatian pemerintah Indonesia saja, namun telah menjadi perhatian dunia. Kebijakan-kebijakan yang dikeluarkan, secara jelas telah mengatur tentang keselamatan nelayan dan kapal ikan, sedangkan implementasi yang dilakukan pada negara-negara anggotanya tersebut masih kurang. Data yang dikumpulkan ada dua jenis, yaitu data primer dan data sekunder. Data primer diperoleh dengan cara wawancara mendalam melalui kuesioner. Pengambilan data dilakukan dengan metode purposive sampling terhadap beberapa pihak yang berkepentingan dengan keselamatan kerja nelayan. Tujuan dari penelitian ini untuk mengidentifikasi pengetahuan nelayan seputar keselamatan kerja, dan mengidentifikasi instansi pengelola keselamatan kerja nelayan. Hasil penelitian ini menunjukkan bahwa nelayan memiliki pengetahuan yang minim mengenai keselamatan kerja dan prosedur bekerja di kapal serta pengelolaan keselamatan kerja di PPI Batukaras tidak terlaksana dengan baik.

Judul: Identifikasi Keselamatan Kerja Nelayan pada Aktivitas Payang di Palabuhanratu, Sukabumi Jawa Barat
Abstrak: The study aimed to describe the fishing activity of the boat seine also to identify the potential hazard or the working risk on the operating of the boat seine in Palabuhanratu. A case study of safety was used on one of the boat seines in Palabuhanratu. Descriptive analysis was used to describe the activities of pre-operation, operation process until post-operation process of the boat seine. Detail description included of the fishing unit and the fishing activity on the boat seine fishery. Job safety analysis (JSA) was used to examine the working method and to determine the potential hazards at every step of the boat seine activity. Based on the result, it was known that the activity of the operation of the boat seine consisted of 13 events, which was divided into 3 stages. The first was pre-operation, which were from preparation on the fishing base, transfer to the ship, sailing to the fishing ground and the gear preparation. The second was operation process, which were setting and hauling the fishing gear. The third was post-operation, which were handling the catch, sailing towards the harbor and then transferring the equipment and the catch from the ship to the dock. JSA analysis result showed that the risk arising was the category of accident which were not severe, severe and very severe. The risk caused by the lack of safety equipment, the tool operation and the skill of the boat seine fisherman. Identified potential hazards at payang activity is 92% in the minor accident class category. Potential hazards in accident class category have a percentage of 8% and the percentage of severe accident class category is 0%. The risks of potential hazards in boat seine operation are caused by the lack of safety equipment, tools and fishermen skills.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
