Judul: Identifikasi Keselamatan Kerja Kegiatan Bongkar Muat Kapal Purse Seine Di Muncar, Banyuwangi
Abstrak: Kegiatan bongkar muat kapal purse seine merupakan kegiatan yang melibatkan banyak orang dan aktivitas. Peluang kecelakaan kerja pada kondisi tersebut dapat terjadi pada setiap tahap aktivitas bongkar muat. Penelitian bertujuan untuk mendeskripsikan aktivitas kegiatan bongkar muat kapal purse seine di PPP Muncar dan mengidentifikasi potensi bahaya pada kegiatan bongkar muat di PPP Muncar. Metode studi kasus digunakan untuk mengidentifikasi keselamatan kerja bongkar muat. Analisis deskriptif dengan pendekatan Hierarchical Task Analysis (HTA) dan Job Safety Analysis (JSA) dilakukan terhadap data observasi langsung di lapangan. Hasil penelitian menunjukkan bahwa terdapat 52 aktivitas pada kegiatan bongkar muat. Analisis HTA dan JSA menunjukkan dari 52 kegiatan tersebut yang memiliki kategori tidak bahaya sebanyak 3 (6%) kegiatan, ringan 28 (54%) kegiatan, menengah 20 (38%) kegiatan, dan berat 1 (2%) kegiatan serta tidak ada kegiatan yang dikategorikan fatal. Hasil wawancara menunjukkan bahwa nelayan yang memiliki pengetahuan mengenai keselamatan kerja saat kegiatan bongkar muat yang diambil dari 50 responden yang ada di PPP Muncar adalah: sangat mengerti 8%, mengerti 36%, cukup mengerti 14%, dan yang tidak mengerti 42%. Adapun nelayan yang sadar akan pentingnya keselamatan kerja pada kegiatan bongkar muat adalah 8% dan yang tidak menyadari pentingnya keselamatan kerja sebesar 92%. Hal yang masih perlu diperhatikan adalah belum adanya Prosedur Operasional Baku (POB) bongkar muat ikan dan perlunya perbaikan fasilitas bongkar muat untuk menekan peluang terjadinya kecelakaan kerja di PPP Muncar.

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: 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.
