Abstract

The research objectives were (1) to examine the difference of productivity level of the catch (hook rate) between the flying bottom longline (RDL) and the conventional bottom longline. (2) record the type and amount of catch. The flying bottom longline (RDL) in this study is a modified construction design of bottom long line, by shortening the branch line and reducing its distance on the main line. The fishing method was changed by spreading the main line on the bottom of the sea. Thus each branch line and hooks will float to the mid surface by taking advantage of the movement of the ocean currents. The research was conducted in August-October 2020 in the waters of the Lembeh Strait, Bitung City, North Sulawesi. The research method used was 6 fishing trips trials. The results of this study indicate that the normality and homogeneity test of the hook rate data distribution is obtained 0.635 for residual value of data normality and a 0.732 of residual value of homogenity, so the data is normally distributed and homogeneous The hook rate on the flying bottom longline (RDL) operated at a depth of 10 m with fresh squid fish bait illustrates that the flying bottom longline hook rate (RDL) is higher than the conventional bottom longline (Rdk). The same thing happened at a depth of 20 m. The hook rate of the flying bottom line (RDL) was higher than that of the conventional bottom line (RDK). The effect of fresh squid bait shows a significant difference in the amount of catch between RDL and RDK. There is a significant difference between RDL and RDK when using decapterus bait. There is no significant difference between the depths of 10 meters and 20 meters on the amount of fish catch. The number of fish species caught using the flying bottom longline (RDL) is eleven species of demersal fish. Total catch using conventional bottom longlines (RDK) is eight species of demersal fish. Keywords: bait; branch line, flying bottom longline; main line, productivity

Abstract

Pancing ulur tuna telah digunakan secara luas oleh nelayan di Laut Sulawesi dan sekitarnya, untuk menangkap ikan pelagis besar dengan kapal-kapal ukuran kecil. Keberhasilan penangkapan tuna hand line, disamping dipengaruhi oleh umpan, juga dipengaruhi oleh teknik pengoperasian. Oleh karena itu, penelitian ini bertujuan untuk mengetahui teknik pengoperasian alat tangkap hand line tunadan hasil tangkapannya.Penelitian ini dilakukan pada bulan September-November 2014 di perairan Laut Maluku dengan KM.Coelacanth milik Politeknik Kelautan dan Perikanan Bitung.Data tangkapan dikumpulkan dengan menggunakan alat tangkap hand line tuna selama 6 trip di perairan Laut Maluku menggunakan analisa deskriptif. Hasil tangkapan madidihang (Thunnus albacares) sebesar 79,9% masih lebih banyak dibandingkan dengan tuna mata besar (Thunnus obesus) yang hanya 20,1%.Kata kunci : madidihang; pancing ulur tuna; teknik pengoperasian

Abstract

The potential for squid in the waters of the Lembeh Strait, Bitung City is overflow. So that potential is utilized by fishermen in Motto village, to catch squid. The purpose of this research was to study the construction and fishing technique of squid fishing gear in Motto Village. The method of data collection was done by interview and direct observation in the field by following the fishing activities directly and The analysis used is descriptive. The results showed that the construction of squid jigging are includng rope reels, main line, hook, swivel. The construction of the squid jigs was modified by adding a tin ballast which was attached to the body of the fishing line as well as functioning as a ballast, and at the end of the body of the fishing rod, radium from scotlet was installed. The technque of catching squid is assisted by turn on flasing ligt of green and white which is dipped on the sea surface to function as an attractor to collect squid making it easy to fishing.

Abstract

Keberlangsungan dan produktivitas galangan kapal kayu di Kabupaten Batang bergantung adanya persediaan dan kelancaran pasokan kayu dari pemasok. Penelitian ini bertujuan untuk menghitung kebutuhan kayu di galangan kapal kayu Kabupaten Batang, mengidentifikasi pemasok dan menghitung ketersediaan pasokan kayu, dan mengidentifikasi alur pasokan kayu. Analisis kualitatif dilakukan secara deskriptif untuk memaparkan hasil-hasil perbandingan antara kebutuhan dan pasokan kayu selama tahun 2014-2018. Kayu yang digunakan  untuk membuat kapal berukuran dibawah 30 GT adalah jenis bengkirai sebesar 70%, kayu rimba campur 17% dan kayu laban 13%. Total kebutuhan kayu selama tahun 2014-2018 jenis kayu bengkirai sebesar 6.431,67 m3 dan jenis kayu rimba campur sebesar 1.561,98 m3. Ada 8 perusahaan yang menjadi pemasok utama di galangan Batang. 2 perusahaan berlokasi di kecamatan Batang, 6 perusahaan berlokasi di Kecamatan Tulis dan  Subah.  Ketersediaan kayu bengkirai (20.439,09 m3) dan rimba campur  (42.550,00 m3 ) di 8 perusahaan. Stok tersebut  masih lebih besar dari jumlah yang dibutuhkan seluruh galangan di Kabupaten Batang  selama tahun 2014-2018, yang hanya sebesar 6.431,67 m3 untuk kayu bengkirai dan sebesar 1.561,98 m3 untuk kayu rimba campur. Alur pasokan kayu dimulai dari supplier (perusahaan Kalimantan dan Maluku), agen kayu di Wilayah Semarang, penjual kayu di Kabupaten Batang, galangan kapal kayu. Kayu dipesan dalam bentuk kayu bulat atau gelondongan, namun kayu dikirim ke galangan dalam bentuk kayu olahan.
