Judul: Keselamatan Kerja Nelayan Bagan Perahu di Pelabuhan Perikanan Nusantara Karangantu, Serang, Banten.
Abstrak: Bagan perahu menjadi salah satu pemasok ikan tertinggi di pelabuhan Karangantu. Kelancaran pengoperasian bagan perahu sangat penting bagi nelayan dan pasokan ikan di pelabuhan. Banyak hal yang menunjang dalam hal kelancaran pengoperasian bagan perahu, salah satunya adalah kesadaran akan keselamatan kerja pada saat pengoperasiannya. Kecelakaan kerja dapat terjadi saat pengoperasian bagan perahu. Hal tersebut disebabkan oleh berbagai faktor, salah satunya adalah kelalaian manusia. Tujuan penelitian ini untuk mengidentifikasi jenis bahaya, menentukan tingkat risiko nelayan, dan memberikan gambaran teknis pengendalian untuk keselamatan kerja nelayan pada pengoperasian bagan perahu. Identifikasi keselamatan kerja menggunakan metode Hazard Identification and Risk Assesment (HIRA). Identifikasi terhadap potensi kecelakaan yang bisa terjadi pada nelayan dalam pengoperasian jaring angkat melalui penilaian risiko kualitatif yaitu, tidak signifikan, minor, sedang, major dan bencana. Analisis risiko pada potensi bahaya yang terjadi pada aktivitas nelayan bagan perahu melalu analisis penilaian risiko terdapat tiga nilai risk index yaitu, significant risk, moderate risk, dan low risk. Secara keseluruhan terdapat 29 aktivitas pada pengoperasian bagan perahu, dimana terdapat empat aktivitas yang memiliki nilai risk index significant risk dan perlu adanya tindakan pengendalian pada potensi bahaya pada aktivitas tersebut, 18 aktivitas yang memilik nilai index adalah low risk dan tujuh aktivitas yang memiliki nilai index adalah moderate risk.

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: Apatite Growth Optimation on Chicken Mucouse by Fourier Transform Infrared (FTIR) Characterization
Abstrak: Some experiment had been conducted to grow apatite from supersaturated solution of calcium phosphate ions on chicken mucouse. The calcium and phosphate ions were originated from Ca(NO3)2 and (NH4)2HPO4. Carbonate ions from (NH4)2CO3 was also used as starting solution. Experiment was carried out within about 5 hours at temperature 370 C and pH 7. Value of Ca+ : PO4 3- was 1.67, while molar ratio of CO3 2- : PO4 3- was 0.5 : 1. Molarity of molar ratio CO3 2- : PO4 3- variated approximately 0.15 : 0.30, 0.51 : 1.02, and 0.90 : 1.80. Mass of mucouse powder was constant 0.75 gram. The analysis result of Fourier Transform Infrared (FTIR) showed that the precipitation was apatite carbonate type A and B. In these experiment it was found out that the mucouse reduce the crystallinity of apatite precipitant, and the growth of apatite crystal was optimum at solution with molar ratio CO3 2- : PO4 3- about 0.15 : 0.30.
