Laut Jawa merupakan perairan dengan potensi ikan pelagis kecil yang didominasi ikan Tembang. Potensi tersebut dapat dimanfaatkan secara maksimal melalui pengetahuan daerah potensi penangkapan ikan. Penentuan DPI (Daerah Penangkapan Ikan) ikan pelagis oleh nelayan Pukat Cincin ( mini purse seine ) yang berbasis di PPN Pekalongan masih menggunakan cara tradisional melalui pengalaman terdahulu sehingga hasilnya kurang maksimal. Tujuan penelitian ini mengkaji nilai rata-rata suhu permukaan laut (SPL) dan konsentrasi klorofil-a secara musiman selama 3 tahun (2016-2018) melalui interpretasi citra satelit Aqua Modis serta menganalisis pengaruhnya terhadap hasil tangkapan ikan Tembang ( Sardinella fimbriata) . Sehingga didapat peta potensi DPI Ikan Tembang pada perikanan mini purse seine di Laut Jawa yang berbasis di PPN Pekalongan. Metode pengambilan data dilakukan melalui observasi lapangan. Metode penentuan daerah potensi penangkapan ikan dilakukan melalui pendekatan SPL dan konsentrasi klorofil-a dengan memperhatikan jalur penangkapan dan kedalaman perairan. Hasil yang didapat yakni rata-rata produksi ikan Tembang tertinggi pada tahun 2016 hingga 2018 di Laut Jawa didapat pada musim peralihan I dengan SPL 28,86oC dan konsentrasi klorofil-a 0,55 mg/m 3 . Analisis pengaruh SPL dan Klorofil-a terhadap hasil tangkapan dilakukan melalui regresi berganda dengan menyertakan uji asumsi klasik. Pengaruh SPL dan Klorofil-a terhadap hasil tangkapan dinilai cukup kuat terlihat dari koefisien korelasi (R) 0,795. Koefisien determinasi (R 2 ) 0,63, artinya SPL dan klorofil-a dapat menjelaskan hasil tangkapan 63%. Terdapat 3 lokasi yang berpotensi sebagai daerah penangkapan di Laut Jawa tepatnya Utara Kota Pekalongan yakni di perairan Tegal, Pemalang dan Pekalongan dengan daerah potensi terluas berada di perairan Pekalongan. The Java Sea is a water region with potential pelagic fish. Mini purse seine fisheries with fishing base on PPN Pekalongan was determined fishing ground by traditional way, so the result was not optimal. The research aims to observe seasonal variability of sea surface temperature (SST) and chlorophyll-a concentration for 3 years (2016-2018) from satellite image data Aqua Modis interpretation and analyze the relationship between catch and SST as well as between catch and chlorophyll-a. Final result from this research is map of Fringe Scale Sardine (Sardinella fimbriata) fishing ground for mini purse seine fishery in the Java Sea.

Electro Shield System (ESS) adalah suatu perangkat elektronik sebagai alat bantu untuk mencegah tertangkapnya biota lasmobranchii yang umumnya sebagai bycatch pada saat operasi penangkapan bottom set gill net . Penelitian ini bertujuan untuk menganalisis pengaruh frekuensi ESS ( Electro Shield System ) sebesar 55 Hz dan 100 Hz selama operasi penangkapan pada jaring insang dasar ( bottom set Gill net ) terhadap biota elasmobranch. Metode penelitian adalah eksperimental fishing, dilakukan di perairan Tanjung Pandan, Bangka. Kepulauan Belitung di Indonesia dari bulan Maret hingga Mei, 2017. Variabel perlakuan adalah operasi penangkapan bottom set gill net yang dipasang alat ESS frekuensi ESS 55 Hz dan 100 Hz dibandingkan dengan bottom set gill net tanpa dipasang ESS (kontrol) untuk mengetahui hasil tangkapan elasmobranchii . Tangkapan Elasmobranch pada bottom set Gill net dengan ESS 55 Hz lebih rendah jumlahnya (5,26%) dibandingkan dengan tangkapan dengan ESS 100 Hz (6,21%) dan tanpa ESS (7,08%). Analisis statistik ANOVA (tanda 0,05) menunjukkan perbedaan yang signifikan antara bottom set gill net dengan dan tanpa ESS 55 Hz dan 100 Hz. Hal ini menunjukkan bahwa ESS dengan frekuensi 55 Hz dapat dideteksi oleh biota elasmobranch dalam organ ampullae lorenzini , sehingga tidak terperangkap pada bottom set Gill net . Electro Shield System (ESS) was an electronic device as a tool to prevent the capture of common lasmobranchii biota as a by-catch during a bottom set gill net capture operation. The aim of research was analysed the effect of ESS (Electro Shield System ) frequency of 55 Hz and 100 Hz during the capture operation on bottom set Gill net against elasmobranch biota. The research method was an experimental fishing, conducted in the Tanjung Pandan waters of the Bangka. Belitung Islands in Indonesia from March to May, 2017. The treatment variable was the bottom set gill net capture operation that is installed ESS 55 Hz and 100 Hz frequency compared to without ESS (control) to find out the elasmobranch catch . Elasmobranch catches on set bottom set Gill nets with ESS 55 Hz were lower (5.26%) compared to catches with 100 Hz (7.08%) and without ESS (7.08 %). Statistical analysis of ANOVA (sign 0.05) shows a significant difference between bottom set Gill nets with and without ESS 55 Hz and 100 Hz. This indicates that an Electro Shield System with a frequency of 55 Hz can be detected by elasmobranch biota in the organs of ampullae lorenzini, so as not to be caught on the bottom set Gill net .
电子系统是一种工具，用来防止拉斯莫布兰奇生物的被捕。这项研究的目的是分析在基本鳃网(elasmobranch biota)捕获吉尔网络(bottom set Gill net)时，其电子盾系统(Electro Shield System)的频率为55赫兹和100赫兹。研究方法是在邦加的丹戎潘丹水里进行的实验钓鱼。印度尼西亚的勿里通群岛，2017年3月至5月。治疗变量是捕获一个位于ESS频率为55 Hz和100 Hz的底层操作，这与不安装ESS网络以了解elasmobranchii捕获的结果相比。Elasmobranch在ginet的底部以ESS 55 Hz的数量为5.26%，比ESS 100 Hz(6.21%)和无ESS(7.08%)的渔数要低得多。ANOVA的统计分析(0.05分)显示了gif net底端与ESS 55赫兹和100赫兹之间的显著区别。这表明，f2h频率55赫兹的ESS可以被lorenzini的ampulta elasmobranch器官检测到，所以它不会被困在ginet的底部。电子系统是一种电子工具，用来预防常见的拉斯莫branchii生物的捕获，就像在吉尔网捕获行动中捕获的那样。研究的目标是分析5hz和100 Hz在对elasmobranch生物的捕获过程中捕获的吉尔网的底部作用。这项研究的方法是一种实验，是在好汉角潘丹水域发现的。2017年3月到5月，印度尼西亚的勿里通群岛。这种变化的治疗是由位于255 Hz和100 Hz的频率所捕获的。Elasmobranch catch在set bottom set with ESS 55 Hz是lower(5.26%)，比较低100 Hz(7.08%)和无ESS(7.08%)。ANOVA统计分析(标志0.05)对底网网的有效区分有5hz和100 Hz。这是一个具有55 Hz频率的电子盾系统，可以由lorenzini大西洋风琴中的elasmobranch生物发现，所以我们不会被Gill net的底部底部发现。

Penelitian ini bertujuan untuk menganalisis pengaruh frekuensi ESS ( Electro Shield System ) sebesar 55 Hz dan 100 Hz selama operasi penangkapan pada jaring insang dasar ( bottom set Gill net ) terhadap biota elasmobranch. Metode penelitian adalah eksperimental fishing, dilakukan di perairan Tanjung Pandan, Bangka. Kepulauan Belitung di Indonesia dari bulan Maret hingga Mei, 2017. Variabel perlakuan adalah operasi penangkapan bottom set gill net yang dipasang alat ESS frekuensi ESS 55 Hz dan 100 Hz dibandingkan dengan bottom set gill net tanpa dipasang ESS (kontrol) untuk mengetahui hasil tangkapan elasmobranchii . Tangkapan Elasmobranch pada bottom set Gill net dengan ESS 55 Hz lebih rendah jumlahnya (5,26%) dibandingkan dengan tangkapan dengan ESS 100 Hz (6,21%) dan tanpa ESS (7,08%). Analisis statistik ANOVA (tanda 0,05) menunjukkan perbedaan yang signifikan antara bottom set gill net dengan dan tanpa ESS 55 Hz dan 100 Hz. Hal ini menunjukkan bahwa ESS dengan frekuensi 55 Hz dapat dideteksi oleh biota elasmobranch dalam organ ampullae lorenzini , sehingga tidak terperangkap pada bottom set Gill net . Electro Shield System (ESS) was an electronic device as a tool to prevent the capture of common lasmobranchii biota as a by-catch during a bottom set gill net capture operation. The aim of research was analysed the effect of ESS (Electro Shield System ) frequency of 55 Hz and 100 Hz during the capture operation on bottom set Gill net against elasmobranch biota. The research method was an experimental fishing, conducted in the Tanjung Pandan waters of the Bangka. Belitung Islands in Indonesia from March to May, 2017. The treatment variable was the bottom set gill net capture operation that is installed ESS 55 Hz and 100 Hz frequency compared to without ESS (control) to find out the elasmobranch catch . Elasmobranch catches on set bottom set Gill nets with ESS 55 Hz were lower (5.26%) compared to catches with 100 Hz (7.08%) and without ESS (7.08 %). Statistical analysis of ANOVA (sign 0.05) shows a significant difference between bottom set Gill nets with and without ESS 55 Hz and 100 Hz. This indicates that an Electro Shield System with a frequency of 55 Hz can be detected by elasmobranch biota in the organs of ampullae lorenzini, so as not to be caught on the bottom set Gill net .","PeriodicalId":193095,"journal":{"name":"SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122011120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hutan mangrove memiliki lingkungan yang sangat kompleks, dimana di dalam dan antar lokasi habitat mangrove saling berbeda. Kajian karakteristik lingkungan penentu distribusi dan kepadatan fauna makro bentik serta hubungannya (studi kasus gastropoda dan kepiting brachyura di kawasan reboisasi mangrove Kepulauan Seribu) telah dilakukan pada bulan Maret 2014. Hal ini bertujuan untuk mengetahui faktor-faktor lingkungan yang berperan terhadap distribusi dan kepadatan gastropoda maupun kepiting brachyura serta untuk mengetahui hubungan antara karakteristik lingkungan dengan distribusi dan kepadatan gastropoda maupun kepiting brachyura di kawasan reboisasi mangrove Kepulauan Seribu. Pengukuran karakteristik lingkungan dilakukan dengan cara insitu, sedangkan data gastropoda dan kepiting brachyura dikumpulkan dengan membuat transek garis dan plot yang ditarik dari titik acuan (tegakan mangrove terluar) dan tegak lurus garis pantai sampai ke daratan. Faktor-faktor lingkungan yang menentukan distribusi dan kepadatan gastropoda maupun kepiting brachyura dianalisis menggunakan Principal Component Analysis (PCA), sedangkan hubungannya digunakan analisis regresi linier sederhana. Hasil kajian memperlihatkan bahwa karakteristik lingkungan yang paling menentukan distribusi dan kepadatan gastropoda maupun kepiting brachyura di kawasan reboisasi mangrove Kepulauan Seribu adalah parameter pH. Hal ini mengindikasikan bahwa semakin tinggi konsentrasi pH perairan, maka kepadatan gastropoda maupun kepiting brachyura juga semakin tinggi. Begitu sebaliknya, semakin rendah konsentrasi pH perairan, maka kepadatan gastropoda dan kepiting brachyura juga semakin menurun. Mangrove forests have a very complex environment, where in and between locations mangrove habitats are different. The study of environmental characteristics determining the distribution and density of benthic macrofauna and their relationship (a case study of gastropods and crab brachyurans in the Seribu Islands mangrove reforestation area) was conducted in March 2014. The research aims to determine environmental factors that contribute to the distribution and density of gastropods and brachyurans crabs and to determine the relationship between environmental characteristics and the distribution and density of gastropods and crab brachyurans in the Seribu Islands mangrove reforestation area. Measurements of environmental characteristics were carried out by insitu method, while data on gastropods and crab brachyurans were collected by making line transects and plots drawn from the reference point (outermost mangrove stands) and perpendicular to the coastline to the mainland. Environmental factors that determine the distribution and density of gastropods and crab brachyurans were analyzed using the Principle Component Analysis (PCA), while the relationship used simple linear regression analysis. The results of the study show that the environmental characteristics that most determine the distribution and density o

“ Kekian ” merupakan salah satu produk diversifikasi perikanan. Kekian yang baik memiliki tekstur yang kenyal dan mudah dikunyah, sehingga perlu gelling agen t (bahan pembentuk gel) untuk bisa membuat gel kekian tersebut tetap baik. Gelatin memiliki sifat sebagai penstabil dan pembentuk gel sehingga mempunyai kemampuan untuk meningkatkan kekuatan gel dan memperbaiki tekstur dari kekian. Tujuan penelitian ini adalah untuk mengetahui karakteristik gelatin dari berbagai jenis kulit ikan dan mengetahui pengaruh penambahan gelatin kulit ikan tersebut terhadap mutu produk kekian . Metode penelitian yang digunakan adalah experimental laboratories menggunakan Rancangan Acak Lengkap (RAL). Perlakuan pada penelitian adalah penambahan gelatin kulit ikan yang berbeda yaitu ikan patin, ikan cobia, dan ikan payus, masing-masing dengan tiga kali pengulangan. Parameter yang diamati adalah gel strength , kadar air, kadar protein, kadar lemak, hedonik, uji gigit, uji lipat, dan uji derajat putih. Data parametrik dianalisis menggunakan ANOVA dan uji lanjut Beda Nyata Jujur, sedangkan data non-parametrik dianalisis menggunakan Kruskall-Wallis dan uji lanjut Mann-Whitney Test .

Lele dumbo merupakan salah satu komoditas penting perikanan budidaya di Indonesia. Perkembangan pengolahan ikan sekarang lebih variatif seperti pengolahan menjadi dendeng. Penambahan asap cair pada proses pembuatan dendeng dapat meningkatkan keawetan dendeng serta memberikan karakteristik sensori. Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan konsentrasi asap cair yang berbeda terhadap kualitas dendeng. Rancangan percobaan yang digunakan adalah RAL (Rancangan Acak Lengkap). Perlakuan meliputi penambahan asap cair 0% sebagai kontrol, 1%, 3%, dan 5%. Parameter uji yang diamati adalah profil asam amino, kadar air, kadar protein, kadar fenol serta uji hedonik (kenampakan, bau, rasa, dan tekstur). Hasil penelitian menunjukkan bahwa dendeng dengan penambahan asap cair tetap memiliki asam amino yang lengkap. Lisin dan leusin dominan pada asam amino esensial dengan nilai 39702,77 - 51736,24 mg/kg, serta pada asam amino non esensial asam glutamat mendominasi dengan nilai 59915,6 - 64478,57 mg/kg. Perbedaan konsentrasi asap cair pada dendeng giling ikan lele dumbo memberikan pengaruh yang nyata terhadap penurunan kadar air, kenaikan protein dan fenol serta hedonik dendeng. Semakin besar konsentrasi yang digunakan, dendeng tidak diterima oleh panelis (p < 0,05). Catfish is one of nutritionally important aquaculture species in Indonesia. Nowadays, the development of its processed method becomes more various such as the production of jerked meat. Addition of liquid smoke could increase shelf life of catfish and give sensory characteristics. This study aimed to determine the effect addition liquid smoke with different concentration on quality characteristics of jerked meat. The research method used Completely Randomized Design (CRD) with four treatments such as addition of 0% liquid smoke as control, 1%, 3%, and 5%. Parameters test observed are amino acid profiles, moisture content, protein content, and phenol content also hedonic test. Jerked meat processed with liquid smoke still have a complete amino acid . Lysine and leucine dominated on essential amino acid with range 39702,77 – 51736,24 mg/kg, while glutamic acid dominated on non essential amino acid with range 59915,6 – 64478,57 mg/kg. Meanwhile, addition of liquid smoke gave a significantly different to the moisture content, protein content, phenol content also appearance, odor, flavor, and texture of catfish jerked meat (p < 0,05).

The research method used Completely Randomized Design (CRD) with four treatments such as addition of 0% liquid smoke as control, 1%, 3%, and 5%. Parameters test observed are amino acid profiles, moisture content, protein content, and phenol content also hedonic test. Jerked meat processed with liquid smoke still have a complete amino acid . Lysine and leucine dominated on essential amino acid with range 39702,77 – 51736,24 mg/kg, while glutamic acid dominated on non essential amino acid with range 59915,6 – 64478,57 mg/kg. Meanwhile, addition of liquid smoke gave a significantly different to the moisture content, protein content, phenol content also appearance, odor, flavor, and texture of catfish jerked meat (p < 0,05).","PeriodicalId":193095,"journal":{"name":"SAINTEK PERIKANAN : Indonesian Journal of Fisheries Science and Technology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122728561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kelurahan Bungkutoko termasuk wilayah administrasi Kota Kendari yang daratannya terpisah karena merupakan wilayah kepulauan. Potensi sumberdaya perikanan yang dimiliki sangat melimpah sehingga menjadi peluang usaha bagi warga setempat dalam peningkatan perekonomian keluarga. Penelitian ini bertujuan untuk untuk menganalisis kelayakan usaha kerajinan tangan yang berbahan dasar kerang kerangan di Kelurahan Bungkutoko. Metode analisis kelayakan finansial meliputi NPV (net present value), IRR (internal rate of return), Net B/C ratio (Net Benefit Cost Ratio), PBP (Pay Back Period), dan BEP (Break Event Point). Hasil yang diperoleh menunjukkan bahwa nilai seluruh kriteria kelayakan finansial yang digunakan menghasilkan nilai yang menunjukkan kategori layak (NPV sebesar Rp10.459.436,-, IRR sebesar 35%, Net B/C 2,03, PBP 12 bulan serta BEP sebesar Rp4.260.943,- dan 154 unit). Hal ini mengindikasikan bahwa usaha kerajinan tangan yang dilakukan oleh wanita nelayan di Kelurahan Bungkutoko layak untuk dilanjutkan Bungkutoko village is included in the administrative area of Kendari City whose land is separated because it is an archipelago. The potential of fisheries resources owned is very abundant so that it becomes a business opportunity for local residents in improving the family's economy. The research aims to analyze the feasibility of a handicraft business based on shellfish shells in Bungkutoko Village. The methods of financial feasibility analysis are NPV (net present value), IRR (internal rate of return), Net B/C ratio (Net Benefit Cost Ratio), PBP (Pay Back Period), and BEP (Break Event Point). The results show that all financial feasibility criteria shows a feasible category (NPV is Rp 10,459,436,-; IRR is 35%; Net B/C 2.03; PBP is 12 months; and BEP is Rp 4,260,943,; and 154 units). It’s indicated that the handicraft business by fishermen women in Bungkutoko Village is feasible to continue.
