Judul: Keselamatan Kerja pada Pembuatan Kapal Model Berbahan Fiberglass
Abstrak: Keselamatan kerja adalah sarana untuk pencegahan kecelakaan, cacat dan kematian sebagai akibat kecelakaan kerja. Penelitian ini bertujuan untuk mengidentifikasi prosedur kerja pembuatan kapal model berbahan fiberglass dan mengidentifikasi secara jelas jenis bahaya pada aktivitas pembuatan kapal model berbahan fiberglass. Penelitian ini dilakukan dengan menggunakan metode studi kasus. Identifikasi keselamatan kerja didapatkan melalui metode hierarchical task analysis. Pengelompokkan potensi bahaya berdasarkan peluang konsekuensi kegagalan yang teridentifikasi berupa tidak berbahaya (pekerjaan tertunda), ringan (tergores dan gatal), menengah (tertusuk dan iritasi kulit), berat (terpotong dan tertimpa kapal) dan fatal (tersengat listrik). Upaya pengendalian yang dilakukan adalah pengadaan alat pelindung diri yang cukup lengkap dan kondisi masih baik, namun masih belum ada kesadaran dari pekerja untuk menggunakan APD (Alat Pelindung Diri) sesuai pekerjaannya. Identifikasi terhadap proses pembuatan kapal model berbahan fiberglass menunjukkan bahwa proses produksi pembuatan badan kapal merupakan proses produksi yang paling berisiko.

Judul: Safety Procedures and Risk Occurrence on  Ship’s Docking Area of Perusahaan Umum Perikanan Indonesia Muara Baru
Abstrak: Galangan kapal merupakan tempat berlangsungnya kegiatan perbaikan, pembuatan dan perawatan kapal. Kecelakaan kerja umumnya terjadi karena kelalaian dan kurangnya pengawasan kerja. Perusahaan lazimnya harus menciptakan lingkungan kerja yang aman bagi para pekerjanya dengan menerapkan keselamatan dan kesehatan kerja, termasuk area docking PT Perikanan Indonesia. Tujuan penelitian ini adalah mengidentifikasi kelengkapan peralatan dan kondisi area kerja docking kapal, mengidentifikasi aktivitas yang berpotensi bahaya bagi pekerja di area docking kapal, serta merekomendasikan solusi untuk menghindari kecelakaan kerja. Metode yang digunakan yaitu analisis deskriptif serta metode Job Safety Analyisis (JSA). Hasil penelitian menunjukkan bahwa masih banyak pekerja area docking yang tidak memperdulikan keselamatan kerja. Konsekuensi bahaya fatal sebagian besar terjadi saat aktivitas docking kapal dikarenakan para pekerja tidak mempunyai pengetahuan tentang perlengkapan khusus untuk bekerja pada ketinggian. Metode JSA digunakan untuk membuat rekomendasi seperti penggunaan alat pelindung diri dan melakukan pengendalian secara teknis dan administratif dimana harapannya dapat mengurangi potensi kemungkinan kecelakaan kerja., A shipyard is where ship construction, repair, and maintenance are carried out. Job incidents commonly happen because of human error and lack of security. A company should create a safe environment by reassuring their employees’ health and safety environment, the docking area of PT Perikanan Indonesia included. The purposes of this study are to identify the completeness and readiness of the equipment and docking workstations, to identify the high-risk situation that can occur to the employers at the docking area, and to propose a solution regarding the prevention of job incidents. The analysis methods used are descriptive analysis and Job Safety Analysis (JSA). The results showed that many employees of the docking area lack awareness of job safety procedures. Fatal failure could occur during docking operations, and it is caused by the dock staff not being familiar with the safety equipment used on heights. It recommends wearing personal protective equipment and conducting technical and administering inspections to prevent many accidents during docking.

Judul: Biological Characteristics of Jatropha curcas Trimonoecious
Abstrak: Physic nut (Jatropha curcas L.) is an original plant from tropical America belonging to the family of Euphorbiaceae and an annual plant of monoecious. Commonly J.curcas have male and female flowers on the same plant. There are currently some J. curcas which have hermaphrodite flowers from monoecious plants, but very rarely. J. curcas with hermaphrodite flowers are classified as andromonoecious type (having hermaphrodite and male in the same plant) and trimonoecious type (having male, female, and hermaphrodite flowers in the plant). Trimonoecious plants with hermaphrodite flowers were tend to perform self-pollination (geitonogamy) and produce a homogenous and high-productivity in next generation. J. curcas plants is difficult in differentiating between monoecious and trimonoecious plants when it seedling, and this is a limiting factor to know development of trimonoecious J. curcas. Trimonoecious J.curcas can be identified after six months of planting, and when it have started flowering. Therefore, the trimonoecious J. curcas biological characteristics needs to be an observation. The trimonoecious trait in J. curcas plants can be identified through several analyses, i.e. the analysis of agronomical characteristics, the chromosomes analysis, the isozyme analysis, and the analysis of pollen viability. The study was conducted in December 2011 - February 2013. The experiments were conducted using the Randomized Complete Block Design for one factor, the J. curcas genotype with 5 replicates. Each unit of the experiment consisted of 5 plants. Aagronomics characteristic analyses were conducted using analysis of variance (ANOVA) followed by the Duncan Multiple Range Test (DMRT) at 5% level. The classification of heritability and Genetic Variation Coefficient (GVC) criteria and relative Phenotypic Variation Coefficient (PVC). The analysis of genetic distance clustering was done using the Minitab 1.5 program clustering method. J. curcas stem trimonoecious characters is the primary branches angle, stem diameter, number of primary and secondary branches have a higher size than monoecious plants. Diameter and thickness fruit flesh origins from monoecious plants larger than fruit from plants trimonoecious. Characteristics of the trimonoecious plants in this study were almost the same with their mother plant. Number chromosomes number of J. curcas plant genotypes have 2n = 22 chromosomes The average length of the trimonoecious plant’s chromosome was longer than the average for monoecious plants. The length of chromosomes can differ among one family, even though the numbers of the chromosomes are similar. Isozymes peroxidase (Rf 0.83) and esterase (Rf 0.20) could be used as markers to differentiate between trimonoecious and monoecious plants. Male flower pollen viability of plant origin trimonoecious have a slower rate of decrease than male flowers monoecious plants. The dendrogram from the cluster analysis results could differentiate between trimonoecious and monoecious plants with a variation coefficient of 27.25.
