Abstract
Tali tambat kapal ikan dari bahan serat Sintetis seperti plastik atau nilon sangat berdampak terhadap pencemaran lingkungan dikarenakan bahan tali tambat kapal ikan dari plastik atau nilon sulit teruai di alam. Permasalahan tersebut dapat diatasi dengan alternatif bahan tali tambat kapal ikan dari serat Alam. Oleh karena itu dilakukan penelitian dengan tujuan membuat tali tambat kapal ikan yang terbuat dari serat Alam yang ramah lingkungan. Pengujian dilakukan dengan menganalisa teknis dan ekonomis tali tambat kapal ikan berbahan serat kulit pohon Waru (Hibiscus tiliaceus), Damiho (Anthocephalus candaba) dan Rami (Boehmeria nivea). Analisa teknis dengan uji kekuatan tarik sesuai standar ASTM D3822 terhadap variasi spesimen tali tambat kapal ikan berdiameter 12 mm, 16 mm dan 20 mm tanpa aplikasi perlakuan perendaman dan aplikasi perlakuan perendaman. Berdasarkan perhitungan hasil pengujian, didapatkan nilai kuat tarik yang memenuhi standar kuat tarik BKI minimal untuk tali sebesar 26,51 MPa, 24,85 MPa dan 22,59 MPa meliputi tali berbahan serat kulit pohon Waru dan Rami, sedangkan untuk hasil kuat tarik tali berbahan serat kulit pohon Damiho tidak memenuhi standar kuat tarik BKI. Nilai kuat tarik tali tanpa perlakuan perendaman berbahan serat kulit pohon Waru dan Rami sebesar 28,92 MPa, 26,58 MPa, 23,67 MPa dan 35,07 MPa, 27,94 MPa 23,76 MPa. Tali tambat kapal ikan berbahan serat kulit pohon Waru lebih ekonomis dan ramah lingkungan dibandingkan tali berbahan serat Sintetis, sedangkan tali beberbahan serat kulit pohon Rami tidak ekonomis dikarenakan biaya pembuatannya lebih mahal dari tali berbahan serat Sintetis. Biaya pembuatan tali tambat berbahan serat kulit pohon Waru sebesar Rp1.221.000, Rp1.788.000 dan Rp2.940.000, dibandingkan harga tali serat Sintetis sebesar Rp1.500.000, Rp2.400.000 dan Rp4.940.000, sehingga dapat menghemat biaya Rp279.000 atau 18,60%, Rp612.000 atau 25,50% dan Rp2.000.000 atau 40,49%.

The mooring ropes of fishing vessels of Synthetic fiber such as plastic or nylon have an impact on environmental pollution because the mooring material of plastic or nylon fishing vessels is difficult to decompose in nature. These problems can be overcome by using alternative materials for fishing vessel’s mooring ropes such as Natural fibers. Therefore, research was carried out with the aim of making mooring fishing vessels made from natural fibers that are environmentally friendly. Research were carried out by analyzing the technical and economic aspects of mooring ropes of fishing vessels made from the skin fibers of Waru (Hibiscus Tiliaceus), Damiho (Anthocephalus Candaba) and Rami (Boehmeria Nivea). Technical analysis with tensile strength test according to ASTM D3822 standard on variations of fishing vessels mooring ropes specimens with 12 mm, 16 mm and 20 mm diameters without being soaked control applications and being soaked handling applications. Based on the calculation of the results, the tensile strength of the specimen fulfil the BKI minimum requirement for ropes tensile strength standard of 26.51 MPa, 24.85 MPa and 22.59 MPa for ropes made from Waru and Rami tree bark. The results of tensile strength test for Damiho fibers does not fulfil the BKI tensile strength standards requirement. The tensile strength of the rope without being soaked applications made from Waru and Rami bark fibers was 28.92 MPa, 26.58 MPa, 23.67 MPa and 35.07 MPa, 27.94 MPa, 23.76 MPa. The mooring ropes of fishing vessels made from Waru bark fiber are more economical and environmentally friendly than Synthetic fiber strings, while the ropes made from Rami bark fibers have more expensive manufacturing costs than Synthetic fiber ropes. The cost of making mooring ropes made from Waru tree bark fiber amounted to Rp1,221,000, Rp1,788,000 and Rp2,940,000, compared to the price of Synthetic fiber ropes of Rp1,500,000, Rp. 2,400,000 and Rp. 4,940,000, thus saving Rp279,000 or 18,60%, IDR 612,000 or 25.50% and Rp. 2,000,000 or 40.49%.
