Rajungan is one of the important crustaceans that have high economic value. Fishermen catch the crab using a trap or bottom gillnet. The two fishing devices are operated passively so that they need a tool to attract the crab. In this study tried to develop lamp technology as a lure of crabs. Responses are an important part of knowing crab behavior. The research was conducted in an experimental laboratory, where environmental conditions were controlled by researchers. The study aimed to analyze the patterns and response rates of crab to different light, including purple, blue, green, orange, red and white. A comparative descriptive analysis is used to determine the differences in patterns formed. The test results showed that the pattern of the crab against different light divided into directly and indirectly. Rajungan was approaching to light direclty for 0,072 m/s and indirectly for 0,036 m/s. The fastest crab rate in blue at 0.081 m/s dan the latest crabs arrive the red light at 0,026 m/s. The rate and pattern of the crab closer to white and blue light are shorter and has a short trajectory that can be suggested as a tool to used bottom gillnet, while the red and orange colors that have a slower rate of crab can be used as a trap.</p> Intan Roihatul jannah Hasly Wazir Mawardi Roza Yusfiandayani Copyright (c) 2019 Intan Roihatul jannah Hasly http://creativecommons.org/licenses/by-nc-sa/4.0 2019-12-19 2019-12-19 10 1 1 14 10.24319/jtpk.10.1-14 UJI COBA LAMPU CELUP LED PADA JARING INSANG SEBAGAI UPAYA MENINGKATKAN HASIL TANGKAPAN https://jagb.journal.ipb.ac.id/index.php/jtpk/article/view/26760 <p>Gillnets is a rectangular fishing gear. The main principle of the methods is blocking movement of the fish. The success of its operation depends on the fish presence in passing the net. The improvements of fishing technique on gillnets need to be done to increase the catch weight. The solution is to innovate the use of attractors in the form of lights to attract fish to come to the fishing gear, so that the passive gillnets do not just wait for the fish through it. The study used experimental fishing method with two units of gillnets simultaneously, which each units with lamp and the other without lamp. The objectives of the studies are to get information on the catch composition, to prove the use of a lamp on the gillnets will increase the catch weight and to determine the net position from the lamp that resulted the highest weight. The result showed that (1) the catch in gillnets with LED underwater lamps (JDL) consist of 10 types, or 2 types more than the gillnets without light emitting diode (LED) lamp (JTL). The eight catch composition consists of mackerel, spanish mackerel, barred queenfish, indian mackerel, great barracuda, moonfish, bigbelly pomfret, and giant trevally. The catch composition from JDL were the amberjack and the black pomfret; (2) The use of lamp on the gillnet proven to increase the catch with JDL total weight of fish was 189.765 g; (3) from position of the net shows that the highest weight was at the first position, such as net number 1, 6, 7, and 12 as much as 108.308 g.</p> Angga Hartono Gondo Puspito Wazir Mawardi Copyright (c) 2019 Angga Hartono http://creativecommons.org/licenses/by-nc-sa/4.0 2019-12-19 2019-12-19 10 1 15 26 10.24319/jtpk.10.15-26 STRUKTUR KOMUNITAS LAMUN DI PULAU WANCI, KABUPATEN WAKATOBI, SULAWESI TENGGARA https://jagb.journal.ipb.ac.id/index.php/jtpk/article/view/28116 <p>Seagrass is sea plant that is no less important to other coastal ecosystems such as coral reefs and mangroves in terms of physical, ecological, and economic. Indonesia has 12 species of seagrasses from 58 species of seagrasses in the world. Not all regions in Indonesia has the same species seagrasses due to differences in environmental conditions or anthropogenic pressures, a study of seagrass species diversity in Indonesian waters need to be done. This research was conducted to indentify seagrass community structure in intertidal area of Wanci waters, Wakatobi Regency, Southeast Sulawesi Province. Stations of observation was located in seagrass bed area that divided in to four stations. Sampling methods was conducted refers to McKenzie <em>et al</em>. (2001) by using quadratic transect 50 cm x 50 cm. In each the quadratic transect, there was recorded of species, and total of the plant. The result of research showed that there were 7 species of segrasses found in Wanci island waters namely <em>Halophila ovalis</em>, <em>Halodule uninervis</em>, <em>Cymodocea rotundata</em>, <em>Thalassia hemprichii</em>, <em>Enhalus acroides</em>, <em>Thalasodendron</em>, and <em>Syringodium isoetifolium</em>. The highest density of seagrass species was dominated by <em>Thalassia hemprichii</em>, <em>Halodule uninervis</em>, and <em>Cymodocea rotundata</em>. The overall distribution pattern of seagrass species were cluster. There is correlation between environmental parameters and seagrass density. Sand substrate has a high positive correlation to the density of seagrass whereas clay substrate, current velocity, salinity, and temperature had a negative correlation (low to high) to the density of seagrass in Wanci Island waters.</p> Nur Ikhsan Neviaty Putri Zamani Dedi Soedharma Copyright (c) 2019 Nur Ikhsan http://creativecommons.org/licenses/by-nc-sa/4.0 2019-12-19 2019-12-19 10 1 27 38 10.24319/jtpk.10.27-38 EVALUASI STANDAR KOMPETENSI KERJA NASIONAL INDONESIA (SKKNI) SUB GOLONGAN PENANGKAPAN IKAN DI LAUT https://jagb.journal.ipb.ac.id/index.php/jtpk/article/view/26797 <p>Competency standard for capture fisheries was esablished in 2013, this standard is supposed to be used as a reference in developing training program and competency assessment. After more than 5 year implementation, it was revealed that the application of the standard had some shortages. These are issue on its relevance to the actual working condition and some needed competencies were not accommodated in the standard (Nurani <em>et al</em>. 2017). To solve this problem, review should be carried out to the process of development and establishment of the standar. Research wascarried out in May-July 2018 with literature review, interviews, both qualitative and quantitative analysis in general. The results show the development and formation process of the standard was performed in accordance with the existing rules. Some issues identified from this process included: (1) acceptability and conformity to the actual working condition, (2) measurability and clarity of the texts, (3) the absence of master plan of competency standard development. (4) engagement of practicioners in standard development team, and (5) certification licences for all member of verification team. There are two priority actions needed to improve the quality of SKKNI development and forming process in the next, i.e. development of RIP SKKNI and increase engagement of practicioners in the process of standard development.</p> Fahmi Shidiq Tri Wiji Nurani Roza Yusfiandayani Copyright (c) 2019 Fahmi Shidiq http://creativecommons.org/licenses/by-nc-sa/4.0 2019-12-26 2019-12-26 10 1 39 48 10.24319/jtpk.10.39-48 EKSTRAKSI KITOSAN DARI CANGKANG RAJUNGAN PADA LAMA DAN PENGULANGAN PERENDAMAN YANG BERBEDA https://jagb.journal.ipb.ac.id/index.php/jtpk/article/view/27817 <p>Research on making chitosan from small crab shells has been done by several researchers before. This study aims to determine the time priority and repetition of immersion in NaOH solution to increase the value of the degree of deacetylation of chitosan. Previously, chitin extracted from crab shells through two cups, namely deproteination and demineralization. The process of deacetylation of chitin was done by varying the immersion time in the NaOH solution (2, 3, and 4) hours also repeated soaking 3, 4, and 5 times. The deacetylation process used 50% (w/v) NaOH solution involving chitin against 1:20 (w/v) NaOH solution at 120°C. The chitosan obtained was analyzed a functional group using FTIR and analyzed the degree of deacetylation (DD) using the titration method. Chitin obtained as much as 12,4% from small crab shell flour. The greatest (best) deacetylation degree of chitosan was obtained during the 4 hours deacetylation process and the number of deacetylation repetitions 5 times with DD of 44,26% and the yield of chitosan 83%. The length of soaking time in NaOH solution was the most determining factor for the value of the deacetylation degree of chitosan produced.</p> Djaenudin Djaenudin Emil Budianto Endang Saepudin Muhamad Nasir Copyright (c) 2019 Djaenudin http://creativecommons.org/licenses/by-nc-sa/4.0 2019-12-31 2019-12-31 10 1 49 59 10.24319/jtpk.10.49-59 TINGKAT KONTAMINASI MIKROBA PADA BEBERAPA UNIT PENGOLAHAN IKAN ASAP PINEKUHE DI KABUPATEN SANGIHE https://jagb.journal.ipb.ac.id/index.php/jtpk/article/view/26537 <p>One of the products processed by smoked fisheries owned by fishermen regency of Sangihe Island is <em>Pinekuhe</em>.

Fishing vessels to catch tuna in Benoa, Bali, are dominated by tuna longline, purse seine, and troll line vessels. Vessels that are up to 30 GT (&gt;30 GT) must install the Vessels Monitoring System (VMS) to surveillance the fishing vessels that are operating following by the regulations. VMS data provide lot of data from vessel movment, but the problem is not used optimally and the analysis of data VMS still in development, therefore this research aims to identify the utilization VMS data for survilliance dan management of tuna longline based at Benoa. The method used was descriptive analysis using a spatial data management application. The results showed that VMS data can be used to know fishing activity such as vessel position, vessel velocity, and vessel movement. Fishing activity with VMS data can indentfy infraction did by tuna longline vessel that indicated transshipment activity, infraction of fishing area, and can used to validate data between logbook data and VMS data when the vessel landed a fish catch at port. Cross matching data between VMS and logbook data show that data suitability from 2016-2018 increase in 2016 suitability data get 53%, then 2017 get 94%, and 2018 get 98%.</p> Muhammad Irsyad Tawaqal Roza Yusfiandayani Mohammad Imron Copyright (c) 2019 Muhammad Irsyad Tawaqal http://creativecommons.org/licenses/by-nc-sa/4.0 2020-02-03 2020-02-03 10 1 109 119 10.24319/jtpk.10.109-119
