Pengaruh Air Gambut Terhadap Ketahanan Impak Komposit Serat Pandan Berduri (Pandanus Tectorius) Dengan Matriks Polyethylene Therepthalate (Pet) Sebagai Alternatif Material Untuk Lambung Kapal

ABSTRACT
This research addresses the critical need for boat hull materials capable of withstanding the acidic and chemically aggressive peatwaters prevalent in Riau Province, Indonesia. The study evaluates the impact resistance of composites made from thorny pandan fiber (Pandanus tectorius) embedded in a recycled PET (Polyethylene Terephthalate) matrix derived from used plastic bottles. Thorny pandan fiber was chosen for its abundance, high tensile strength, and eco-friendly properties. The PET-B matrix offers a sustainable solution for plastic waste utilization while enhancing composite strength. The composites were fabricated using the hand lay-up method with a 30% thorny pandan fiber and 70% PET-B weight fraction. Impact tests were conducted using the Charpy method, conforming to ASTM D5942-96 standards, with immersion times in peatwater varied at 0, 25, and 50 days. The results revealed a significant decrease in impact strength, dropping from 4.494 kJ/m² (25 days of immersion) to 2.487 kJ/m² (after 50 days), equivalent to a 45.9% reduction. This decline is attributed to the degradation of lignin and the weakening of the fiber-matrix interface due to the acidic nature and organic content of the peatwater. Although the impact strength values did not meet the minimum standards of the Indonesian Classification Bureau (25–45 kJ/m²), this research highlights the potential of thorny pandan fiber and PET-B as environmentally friendly alternative materials for small boat hulls.
