Abstract

Bubu lipat adalah alat tangkap yang digunakan untuk menangkap rajungan di Perairan Karimunjawa. Umpan yang biasa digunakan yaitu ikan segar (Damselfish), namun memiliki kendala sehingga peneliti memberikan solusi menggunakan umpan limbah kepala udang (Paneus merguensis) karena murah, bisa didapat dari limbah rumah tangga, serta mengandung protein yang dapat merangsang indera penciuman Rajungan (Portunus pelagicus). Tujuan penelitian adalah menganalisis hasil tangkapan Rajungan (Portunus pelagicus) dengan bubu lipat umpan limbah kepala udang (Penaeus merguensis) dan umpan ikan segar (Damselfish), serta perbedaan waktu immersing (6 jam dan 12 jam). Metode penelitian yang digunakan adalah experimental fishing dengan 8 kali pengulangan. Penelitian dilakukan di Perairan Karimunjawa, Kabupaten Jepara pada bulan Februari 2018. Analisis data menggunakan uji normalitas, uji homogenitas, dan uji-t. Hasil tangkapan Rajungan (Portunus pelagicus) dengan umpan limbah kepala udang lebih sedikit dibandingkan dengan umpan ikan segar (Sig. 0,538). Hasil tangkapan Rajungan (Portunus pelagicus) pada waktu immersing 6 jam lebih banyak dibandingan waktu immersing 12 jam (Sig. 0,512). Tidak terdapat interaksi antara umpan dan waktu immersing terhadap hasil tangkapan Rajungan (Portunus pelagicus) pada penangkapan bubu lipat di Karimunjawa.

 

Trap is one of the fishing gear used to catch a swimming crabs in Karimunjawa. Usually the bait is used fresh baits (Damselfish), but have constraints so the researcher giving a solution to use shrimp head waste (Penaeus merguensis) because cheap, can get from household waste, and contains protein that can stimulate the sense of swimming crabs’s smell. The research purposes to analyze the ratio of the catches between pot using shrimp head waste (Penaeus merguensis) with fresh baits (Damselfish) and immersing time difference (6 hours and 12 hours). The research method used in this study was the experimental fishing with 8 times repetition. The research held at Karimunjawa waters of Jepara District on February 2018. The data analysis used were the normality test, the homogenity test and t-test. The resulted of swimming crabs on the pot with shrimp head waste is less more than fresh baits (Sig. 0,538) . The resulted of swimming crabs on pot with 6 hours of immersing time is in the largest number of catch (Sig. 0,512). Fresh fish baits and shrimp head waste feed and immersing time between 6 hours and 12 hours no interaction the catch of swimming crabs in Karimunjawa
