Abstract

Dewasa ini, ketersediaan kayu di Indonesia sebagai bahan baku pembuatan kapal ikan sulit diperoleh. Masalah keterbatasan kayu dapat diatasi dengan penggunaan bambu laminasi sebagai material konstruksi kapal ikan. Kondisi kamar mesin kapal ikan yang rentan terjadi tumpahan bahan bakar dan minyak pelumas berdampak pada sifat mekanis bambu laminasi. Penelitian ini bertujuan untuk mengetahui pengaruh tumpahan bahan bakar dan minyak pelumas terhadap sifat mekanis bambu laminasi. Uji tarik uji dan tekuk dilakukan pada spesimen bambu laminasi berdasarkan standar ASTM D3500 dan ASTM D3043. Spesimen direndam bahan bakar (biosolar) dan minyak pelumas (SAE 40). Perendaman dengan bahan bakar dilakukan pada suhu ruang, sedangkan perendaman dengan minyak pelumas dilakukan pada variasi suhu 30 °C, 50 °C, dan 100 °C. Perendaman dengan bahan bakar dan minyak pelumas dilakukan selama 12 jam, 24 jam, dan 48 jam. Berdasarkan hasil pengujian, sifat mekanis spesimen bambu laminasi yang direndam bahan bakar menurun seiring dengan lamanya perendaman, dimana didapatkan kuat tarik variasi 12 jam sebesar 121,070 MPa, variasi 24 jam sebesar 105,802 MPa, dan variasi 48 jam sebesar 97,909 MPa, berikut kuat tekuknya secara berurutan sebesar 98,470 MPa; 82,033 MPa; dan 75,093 MPa. Berbeda dengan bahan bakar, sifat mekanis spesimen bambu laminasi yang direndam minyak pelumas meningkat seiring dengan tingginya suhu dan lamanya perendaman, dimana didapatkan kuat tarik variasi suhu 30 °C selama 12 jam sebesar 106,485 MPa, selama 24 jam sebesar 111,467 MPa, dan selama 48 jam sebesar 120,952 MPa, berikut kuat tekuknya secara berurutan sebesar 82,682 MPa; 88,948 MPa; dan 102,298 MPa. Kuat tarik dan kuat tekuk terendah dari seluruh hasil pengujian adalah sebesar 97,909 MPa dan 75,093 MPa. Berdasarkan regulasi BKI tahun 2013 tentang Kapal Kecil ≤ 24 meter, bambu laminasi masih layak digunakan sebagai material konstruksi kapal ikan, khususnya di daerah kamar mesin yang rentan terkena tumpahan bahan bakar dan minyak pelumas. =============================================================================================== Nowadays, the availability of wood in Indonesia as a raw material for fishing ship manufacture is difficult to obtain. Wood availability problems can be overcome with the use of laminated bamboo as a material for fishing ship construction. The condition of fishing ship engine room which is susceptible to fuel and lubricant oil spills affects the mechanical properties of laminated bamboo. This research aims to know the effect of fuel and lubricant oil spills against mechanical properties of laminated bamboo. Tensile test and flexure test performed on laminated bamboo speciments based on ASTM D3500 and ASTM D3043 standards. Speciments soaked in fuel (biosolar) and lubricant oil (SAE 40). Fuel soaking is carried out at room temperature, while lubricant oil soaking is carried out within variations of temperature of 30 °C, 50 °C, and 100 °C. Fuel and lubricant oil soaking are carried out during 12 hours, 24 hours, and 48 hours. Based on the test results, mechanical properties of laminated bamboo speciments soaked in fuel decreased along with the soaking duration, where obtained tensile strength of variation of 12 hours is 121.070 MPa, variation of 24 hours is 105.802 MPa, and variation of 48 hours is 97.909 MPa, following their flexure strength in consecutive are 98.470 MPa, 82.033 MPa, and 75.093 MPa. In contrast to fuel, mechanical properties of laminated bamboo speciments soaked in lubricant oil increased along with the increment of soaking temperature and duration, where obtained tensile strength of variation of 30 °C during 12 hours is 106.485 MPa, during 24 hours is 111.467 MPa, during 48 hours is 120.952 MPa, following their flexure strength in consecutive are 82.682 MPa, 88.948 Mpa, and 102.298 MPa. The lowest tensile strength and flexure strength from the entire test results are 97.909 MPa and 75.093 MPa. Based on BKI 2013 edition regarding Small Vessels up to 24 meters regulation, laminated bamboo is still comply used as a material for fishing ships construction, especially in the area of engine room which is susceptible to fuel and lubricant oil spills.
