Abstract

Mendong merupakan tanaman budidaya yang memiliki potensi ekonomis yang cukup baik tidak hanya sebagai produk tradisional dalam bentuk kerajinan, namun dapat dijadikan bahan baku komposit serat alam. Oleh karena itu, tujuan penelitian ini adalah untuk mengetahui karakteristik mekanik komposit Mendong/Epoksi BAKELITE EPR 174, yaitu komposit dengan penguat serat mendong yang sudah dilakukan treatment alkali dan matriks Epoksi BAKELITE EPR 174. Metode manufaktur komposit menggunakan hand lay up. Pengujian kekuatan tarik spesimen komposit menggunakan ASTM D 3039/D 3039M dengan arah orientasi serat Unidirectional 0° dan 90°. Selanjutnya data hasil uji dianalisis menggunakan Distribusi Weibull untuk mengetahui keandalan komposit. Berdasarkan hasil analisis menunjukkan bahwa nilai keandalan komposit Mendong/ Epoksi BAKELITE EPR 174 Unidirectional 00 pada 90% dan 50% masing-masing sebesar 20,7 MPa dan 26,8 MPa , sedangkan pada Unidirectional 900 sebesar 0,11 MPa dan 0,36 MPa.

Abstract

Ship sanitation is one of the efforts aimed at environmental health risk factors on board. The results obtained from the Port Health Office (KKP) Class II Samarinda, there are several types of ships that are routinely carried out sanitary inspections of ships, one of which is a passenger ship. Therefore, researchers want to examine the Sanitary Relationship of Ships With Signs of The Presence of Cockroaches On Passenger Ships Leaning in The Port of Class II Samarinda. The design of this study is an observational analytical method with cross sectional study design. The instruments in this study used the ship's sanitation inspection form and the cockroach inspection form on the passenger ship. The data is processed using Fisher Exact Test. Based on the results of the study, where the 5 vessels that were examined have met the sanitary requirements (100%) in accordance with The Minister of Health Regulation No. 40 of 2015 concerning Certificate of Ship Sanitation. The results of the study found signs of the presence of cockroaches on the ship as many as 4 units of ships (80%). The results of statistical tests processed by Fisher Exact Test obtained the following results, p-value count = 0.20 > from p-value α = 0.05 so that the conclusion H0 received, which means "No Relation to Ship Sanitation with Signs of The Presence of Cockroaches On Ships Leaning in Samarinda Port".
