CORRECTION OF BLUE SWIMMING CRAB FOLDING TRAP ENTRANCE

Abstract

Bubu lipat rajungan banyak digunakan oleh nelayan Indonesia karena mudah dibuat, dioperasikan. Hasil pengamatan menunjukkan bahwa rajungan sering mengalami kesulitan ketika melewati lintasan masuk, karena kaki-kakinya terperosok ke dalam mata jaring. Duri-duri pada sisi badannya sering tersangkut pada benang jaring, karena celah masuk terlalu sempit. Akibatnya adalah peluang rajungan terperangkap menjadi sangat rendah. Tujuan penelitian pertama adalah memperoleh kombinasi sudut kemiringan dan ukuran mata jaring lintasan yang mudah dilewati rajungan. Penelitian mencoba mengombinasikan antara sudut lintasan 20°, 30°, dan 40° dengan ukuran mata jaring 0,125”, 0,35”, dan 1,25”. Adapun tujuan kedua adalah menentukan celah masuk berbentuk elips atau persegi panjang yang mudah dilalui oleh rajungan. Penelitian skala laboratorium dan data hasil penelitian diuji secara parametrik dengan analisis ANOVA dua arah dan Tukey. Hasil penelitian menunjukkan kombinasi sudut 20° dan ukuran mata jaring 0,125” merupakan konfigurasi terbaik, karena sebanyak 26 rajungan dapat melewati celah masuk. Kombinasi berikutnya, 20° (0,35”) dan 30° (0,125”) masing-masing dilalui oleh 25 rajungan. Sebanyak 369 individu (63,6%) dapat melewati celah persegi panjang, sedangkan 211 individu (36,4%) lainnya melewati celah elips. Kombinasi sudut 20° dan ukuran mata jaring 0,125” dengan bentuk celah masuk persegi panjang lebih mudah dilewati rajungan dibandingkan dengan kombinasi lainnya.
