The presence of biofouling has an impact on the ship’s performance, which is reduced to require more fuel, in the end, it contributes significantly to cost increases. Biofilms provide a suitable substrate for the growth of microorganisms. Ship hull as a substrate for biofilms has many kinds of material. Steel, wood, laminated bamboo, and fiber are often used for ship hulls. Different material makes different characteristics of substrate for biofilms. The aim of this research is to determine the growth rate of biofouling in each shipbuilding material and to find out which vessel material is suitable for use in the Bali Strait. The experiment was located in Boom Marina, Banyuwangi. The materials used in this research are wood, laminated bamboo, and fiber. The daily growth rate (DGR) is calculated every week of observation. Wood had the most biofouling with a DGR of 2,646 g/day. Laminated bamboo had the least biofouling in this research after 2 months of immersion with a DGR of 0,086 g/day. Keywords: Biofouling, shipbuilding material, daily growth rate.
Pemilihan sudut deadrise pada planing hull dan pengaruh pada kurva beban propeler dilakukan untuk memberikan gambaran yang jelas terhadap pemilihan mesin utama dan kecepatan kapal. Sehingga, tujuan penelitian ini adalah bagaimana pengaruh sudut deadrise terhadap kurva beban propeler. Sudut deadrise yang dipilih antara lain 7°, 10°, 13°, dan 18°. Metode yang digunakan adalah pendekatan teoretis dengan bantuan data series seperti data Propeller Wagenigen B-Series. Hasil penelitian menunjukkan bahwa perubahan tahanan karena perbedaan sudut deadrise mempengaruhi kurva beban propeler dengan nilai persentase perbedaan yang hampir sama. Perbedaan persentase nilai tahanan masing-masing sudut deadrise adalah 0,057% (rata-rata selisih tahanan yaitu 33 N) dan perbedaan daya propeler hanya berkisar 0,05%. Sehingga, dapat disimpulkan bahwa perbedaan sudut deadrise pada penelitian ini memberikan pengaruh yang hampir sama dengan perbedaan nilai tahanan kapalnya.
Wisata sasak gantung merupakan salah satu destinasi wisata yang berlokasi di Desa Genteng Kulon, Kecematan Genteng, Banyuwangi. Destinasi ini berupa jembatan gantung yang terletak di atas Dam (bendungan) sungai Setail, Genteng. Dalam upaya optimalisasi destinasi wisata tersebut, tim pengabdian bekerja sama dengan Desa Genteng Kulon untuk membuat program yang sekiranya menarik minat wisatawan. Program tersebut yaitu wisata air menggunakan perahu fiber glass. Dalam hal ini, tim pengabdian mendesain dan membuat perahu fiber glass untuk menunjang program tersebut. Perahu fiber glass terbuat dari bahan matriks polyester yang diperkuat serat kaca (fiber glass). Fabrikasi perahu fiber glass menggunakan metode hand lay-up. Tahapan utama pembuatan perahu fiber glass ada tiga yaitu pembuatan cetakan, proses laminasi, dan finishing (pengecatan). Perahu fiber glass tersebut berukuran panjang 2.8 m, lebar 1.0 m, dan tinggi geladak 0.8 m. Adanya perahu fiber glass ini dapat meningkatkan minat wisatawan untuk berkunjung ke destinasi sasak gantung yang berlokasi di Genteng Kulon, Banyuwangi.
An anthropometric study of Indonesian people use ship in economy class in East Java was conducted. Fifty-eight body dimensions, age, body weight, and hand squeeze strength for chair design importance were measured for 300 Indonesian males, comprising Javanese (150) and Madurese (150) tribes. The two tribes were compared to identity similarity and contrast existing in their respective body dimensions. Descriptive statistics provided mean, standard deviation, percentile value and coefficient of variance of each population. The survey also revealed that the mean values of hand squeeze strength of Javanese males were higher than the Madurese have. For ergonomically design for seat of ship is as follows seat
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
