<![CDATA[Penelitian ini bertujuan untuk menentukan bentuk dan posisi pemasangan celah pelolosan serta selektivitas pada bubu lipat balok. Penelitian dibagi dalam dua tahap, yaitu penelitian di laboratorium dan di lapangan. Penelitian di laboratorium dilaksanakan antara Januari - Mei 2012 dan penelitian di lapangan dilaksanakan di Teluk Mutiara Kabupaten Alor, Provinsi Nusa Tenggara Timur antara Juni - November 2012. Data penelitian di laboratorium dan di lapang dianalisis secara deskriptif komparatif. Adapun data untuk selektivitas bubu lipat dianalisis dengan model selektivitas logistik dengan dukungan persamaan metode maximum likelihood dan program Solver dari Microsoft Excel. Hasil penelitian menunjukkan bahwa bentuk celah pelolosan yang sesuai untuk meloloskan kepiting bakau adalah celah berbentuk persegi panjang. Posisi celah pelolosan yang paling banyak meloloskan kepiting muda adalah celah pelolosan bagian depan (CP depan). Nilai selektivitas bubu lipat (dengan nilai CW50) untuk posisi CP depan: 6,6 cm, CP sudut bawah: 6,5 cm, CP samping atas: 6,4 cm dan CP sudut atas: 6,2 cm. Celah pelolosan yang lebih selektif terhadap ukuran kepiting bakau adalah CP samping atas. The study was aimed to determine the shape and installed position of escaping gap equipment and the selectivity of the pot based on the escaping gaps. The study was conducted in experimental laboratory from January to May 2012 and the field experiment was carried out in Mutiara Bay, Alor District, Province of Nusa Tenggara Timur between June to October 2012. The data were analysed by using comparative descriptively. The pot selectivity was analysed by using logistic model and it was supported by using formulation of Maximum Likelihood Method and SOLVER of Microsoft Excel. The results showed that the appropriate of escaping gap shape was rectangular escaping gap and the escaped gap at front position of the pot which the escaped of young crabs were higher than the other escaped gaps. The pot selectivity based on CW50 with escaping gap at front position was 6.6 cm, under side position of 6.5 cm, top corner position of 6.4 cm and upper side position of 6.2 cm. The selectivity of escaping gap at front position was higher than the other escaping gap position.]]>
