STABILITAS SAMPAN DENGAN BILGE KEEL PADA SUDUT 30 DAN 60 DERAJAT Muhammad Agam Thahir; Muhammad Arif Nasution
JURNAL PERIKANAN TROPIS Vol 5, No 2 (2018)
Publisher : Universitas Teuku Umar

Pembuatan sampan berbahan ember cat bekas diharapkan dapat menjadi alternatif pengganti kayu yang semakin sulit diperoleh dan pengganti bahan serat fiber yang tidak murah. Namun sampan ini memiliki kekurangan, yakni stabilitasnya yang rendah. Bobotnya yang ringan membuat sampan mudah oleng meskipun hanya beroperasi diperairan yang relatif tenang. Oleh karenanya instalasi sirip peredam oleng (bilge keel) diharapkan dapat meningkatkan stablitas sampan ini. Tujuan penelitian ini adalah untuk mendapatkan nilai stabililitas sampan dengan instalasi bilge keel pada sudut yang berbeda dalam rangka mendapatkan stabilitas sampan yang baik. Ukuran sampan yang dijadikan obyek dalam penelitian ini adalah panjang (LOA) 3,15 m; lebar (B) 0,64 m; dalam (D) 0,30 m. Metode simulasi numerik untuk mendapatkan nilai stabilitas serta beberapa parameter seakeeping (pitching, roling dan heaving) digunakan dalam penelitian ini dengan bantuan perangkat lunak yang sesuai. Hasil analisis menunjukkan bahwa terdapat perbedaan stabilitas yang ditunjukkan oleh nilai lengan GZ (righting arm) pada sampan yang dipasangi bilge keel dengan sudut 30 dan 60 derajat sebesar 0,002 m. Bilge keel dengan sudut 30 derajat memberikan nilai stabilitas yang lebih besar dibandingkan dengan sudut 60 derajat.

The decline in mangrove vegetation density and the area of mangrove forests in the coastal province of Riau occurred due to the logging of mangrove forests and the conversion of mangrove forests into other uses such as industrial estates. This study aims to collect a database of mangrove ecosystems which includes the ecological structure of R. apiculata in Riau Province. Collecting data of mangrove vegetation condition was done by transect line and plot. The line transect was drawn from the reference point (the outer mangrove stand) with the direction perpendicular to the coastline to the mainland and made plots according to the category. The results showed that the population of R. apiculata was found in large numbers at Station 3 (350 ind) and a small/small amount was found at Station 1 (137 ind). In addition, Stations 1, 2 and 4 have only one grouping population of R. apiculata based on the Bhattacharya method, while Station 3 has two groupings. Furthermore, the highest R. apiculata density for tree category was obtained at Station 4 (1433.33 ind/m2), saplings category at Station 3 (10488.89 ind/m2) and seedlings category at Station 4 (3666667 ind/m2). Furthermore the water temperature ranged from 28.3 – 30.7°C, salinity 27.3 – 31.3, pH 7.3 – 7.9, DO 5.2 – 6.4 and redox potential ranged from 102 – 124 mV. Based on the standard criteria and guidelines for determining mangrove damage according to the Decree of the Minister of Environment No. 201 of 2004, the population density of R. apiculata at the research location is still classified as medium and refers to the Decree of the State Minister of Environment No. 51 of 2004 concerning Sea Water Quality Standards for Marine Biota, as a whole the range of measured water quality parameters is still within tolerance limits for life mangroves.

Man-made debris exist in every ocean and contaminate marine habitats. Solid materials, typically waste, that has found its way to the marine environment is called marine debris. Composed largely of plastics, marine debris can include cigarette filters, baby diapers, automobiles, six-pack rings, beverage bottles and cans, disposable syringes, plastic bags, bottle caps, fishing line and gear, and thousands of other objects. Plastic items are the most abundant type of marine debris on a global scale and plastic is also the most frequently reported material in encounters between debris and marine organisms. There are various sources of marine debris from activities both on land and at sea. Land-based sources include littering, losses from plastic manufacturing plants, landfills and storm drains.While sea-based sources include fishing gear, garbage from shipping and recreational boats, offshore drilling platforms and rigs. Marine debris is more than an unsightly inconvenience for beach-bound vacationers or pleasure boaters. It also affects the inhabitants and economies of coastal and waterside communities worldwide. In addition to the increasingly well-recognised problems that marine debris causes to the environment, coastal communities and marine industries, there is now compelling evidence of the large-scale and serious threat that it poses to the welfare of wild marine animals. The resulting poor welfare, outlined and summarised in this report, creates a compelling argument that marine debris must be viewed not only as a serious environmental, conservation, human health and economic issue, but also as a significant global animal welfare issue that requires urgent action.
