Abstract

Illegal, Unreported and Unregulated (IUU) fishing poses a significant challenge to the management of marine and fisheries resources. This practice brings negative impacts on several aspects, including the economy. To address this problem, the Government of Indonesia established a special Task Force to Combat Illegal Fishing, which later  is known as Task Force 115, through a Presidential Regulation Number 115 of 2015. Task Force 115 was formed with a mandate to execute law enforcement operations to combat illegal fishing.  In general, the existence of Task Force 115 brings favourable impacts to the economy, especially from the fisheries sector. It should be noted that, because Task Force 115’s main tasks are enforcement related, the impacts to the economy are not direct. The purpose of this study was to analyse the role of the Task Force 115 in IUU fishing eradication activities that occur in the jurisdictional areas of the  Republic of Indonesia in terms of the economic fisheries. Efforts of combating illegal fishing does not necessarily generate an increase in fisheries GDP, tax income and exports. Instead, those positive impacts are attributed to a set of policies imposed by the Ministry of Marine Affairs and Fisheries since 2014, which oriented to the responsible and sustainable fisheries. The establishment of Task Force 115 was part of that. Task Force 115’s works created deterrence and triggered compliance of fisheries business actors with the prevailing laws and regulations. Compliance eventually brings positive impacts on the economy. In 2015, growth of fisheries GDP, which amounted to 8,37%, surpassed national GDP of 4.79%. The growth of fisheries GDP reached its peak during the fourth quarterly of the year, which is 8,96% from last year’s during the same period. In 2016, the growth of fisheries GDP reached 5.15%.

Abstract

Edible film merupakan salah satu pengemas yang digunakan untuk menambah fungsi pengawetan dengan ditambah S.platensis sebagai antioksidan pada bahan pangan karena bersifat biodegradable atau dapat terurai oleh mikroba. S. platensis digunakan sebagai senyawa antioksidan karena mempunyai kandungan pigmen fikosianin. Penambahan Serbuk S. platensis  dengan konsentrasi 1%, 1,5% dan 2% digunakan sebagai barrier terhadap kerusakan produk akibat oksidasi dan ketengikan makanan.Tujuan penelitian ini adalah mengetahui pengaruh penambahaan serbuk S.platensis berbeda terhadap karakteristik edible film alginat dan mendapatkan konsentrasi serbuk S.platensis terbaik edible film. Metode penelitian yang digunakan bersifat eksperimental laboratories dengan rancangan percobaan Rancangan Acak Lengkap (RAL). Parameter yang diamati adalah uji ketebalan, kuat tarik, persen pemanjangan, laju transmisi uap air, kelaruan, total fenol dan aktivitas antioksidan ABTS (2,2'-azino-bis(3-ethylbenzothiazoline6-sulphonic acid). Data dianalisis menggunakan Analisa sidik ragam (ANOVA). Untuk mengetahui perbedaan antar perlakuan, data diuji dengan uji lanjut BNJ. Hasil penelitian menunjukkan bahwa perbedaan konsentrasi S. platensis berpengaruh nyata (P<0,05) terhadap nilai ketebalan, kuat tarik, persen pemanjangan, kelarutan, laju transmisi uap air, total fenol dan aktivitas antioksidan ABTS. Konsentrasi terbaik edible film alginat dengan penambahan serbuk S.platensis yaitu 1 % dengan nilai ketebalan 0.2 mm , kadar fenol 52.373 %, aktivitas antioksidan 37.695% dan kelarutan 50.21%. Namun pada laju transmisi uap air cenderung tinggi karena pengaruh gliserol yang bersifat hidrofilik. Edible film is one of the packaging used to increase the preservation function with added S. platensis as an antioxidant in food because it can biodegrade or can be decomposed by microbes. S. platensis is used as an antioxidant compound because it contains phycocyanin pigment. The addition of S. platensis powder with concentrations of 1%, 1.5% and 2% is used as a barrier against product damage due to oxidation and rancidity of food. This research aimed to know the effect of the addition concentration of S. platensis powder to the characteristics of the edible film of alginate and the best concentration of S. platensis powder to make an edible film.. This research used experimental laboratory methods with a completely randomized design (CRD) experimental design. The parameters of this research were thickness, tensile strength, elongation percentage, vapor transmission rate, solubility test, total phenol and antioxidant activity of ABTS (2,2'-azino-bis (3-ethylbenzothiazoline6-sulphonic acid). The data were analyzed using analysis of variance analysis (ANOVA). Further tests needed to know the difference between each treatment used HSD. The results showed that the different concentrations of S. platensis powder had a significantly affected (P<0.05) thickness, tensile strength, elongation percentage, solubility, vapor transmission rate, total phenol and ABTS antioxidant activity The best concentration of edible film alginate with the addition of S. platensis powder was 1% with the thickness value of 0.2 mm, phenol content of 52,373%, antioxidant activity of 37,695% and solubility of 50.21%. However, the test result of the vapor transmission rate tended to be high due to the addition of glycerol which is hydrophilic

Abstract

Permasalahan utama dalam kegiatan usaha budidaya perikanan antara lain adalah ketersediaan benih ikan yang tepat waktu, tepat jumlah dan berkualitas. Ketersediaan benih ikan sangat tergantung pada jumlah telur yang dapat dibuahi dan ditetaskan. Semakin tinggi presentase pembuahan dan penetasan maka akan semakin tinggi pula jumlah larva yang dapat dihasilkan. Penelitian ini menggunakan ikan lele sebagai hewan coba dengan tujuan untuk mengetahui pengaruh suplementasi kurkumin dan tiroksin pada induk ikan lele terhadap kualitas dan performa telur yang dihasilkan. Suplematasi kurkumin dan hormon tiroksin melalui pakan selama 12 minggu pemeliharaan. Parameter yang dianalisis berupa konsentrasi vitelogenin telur, diameter telur, koefisien keragaman diameter telur, konsentrasi lipid dalam telur (triglserida, kolesterol dan HDL), derajat pembuahan dan derajat penetasan. Hasil penelitian menunjukkan bahwa kelompok perlakuan yang diberikan kombinasi penambahan kurkumin dan hormon tiroksin memiliki nilai konsentrasi vitelogenin (8.17+2.74 µg/mL) (p<0,05), diameter telur (1.43+0.00 mm) (p<0,05), dan konsentrasi trigliserida (4.89+0.53 mg/g) (p<0,05) tertinggi diantara semua perlakuan, sementara itu kelompok perlakuan yang baik hanya diberikan penambahan kurkumin, maupun kombinasi penambahan kurkumin dan tiroksin cenderung memiliki nilai derajat pembuahan dan penetasan yang lebih tinggi dibandingkan dengan kelompok perlakuan yang tidak diberikan penambahan kurkumin.  The main problem in aquaculture is the availability of fish seedlings on time, in the right quantity and quality. The availability of fish seeds is determined by the number of eggs that can be fertilized and hatched. The higher the percentage of fertilization and hatching, the higher the number of larvae that can be produced. This study uses catfish as experimental animals because catfish are one of the most consumed cultivation commodities. The aim of this study is to determine the effect of curcumin and thyroxine supplementation on catfish brooders on the quality and performance of eggs produced. Catfish used in this experiment were given the addition of curcumin and thyroxine hormone through the feed for 12 weeks of rearing. Parameters analyzed were egg vitellogenin concentration, egg diameter, coefficient of diversity in egg diameter, lipid concentration in eggs (triglycerides, cholesterol, and HDL), degree of fertilization and degree of hatching. The results showed that the group given the combination of the supplementation curcumin and the thyroxine hormone had the values of vitellogenin concentration (8.17+2.74 µg/mL) (p <0.05), egg diameter (1.43+0.00 mm) (p <0.05), and triglyceride concentration (4.89+0.53 mg/g) (p <0.05) the highest among all treatments, meanwhile the group is only given the addition of curcumin, and the combination of supplementation of curcumin and thyroxine tends to have higher values of fertilization and hatching compared to the group which is not given the addition of curcumin.

Abstract

Sinularia gibberosa is one of the soft coral species reported to produce bioactive compounds for pharmaceutical’s potential. Soft corals produce compounds with antibacterial and antioxidant properties. This study aimed to obtain a bioactive profile of S. gibberosa, which could scavenge DPPH radicals and inhibit the growth of Listeria monocytogenes, Pseudomonas aeruginosa, and Salmonella typhimurium. The research included a sampling of soft corals, extraction by maceration, identification of chemical profiles using LC-HRMS, the assay for antibacterial activity (well-diffusion method), antioxidant assay (DPPH method), and total phenolic content (Folin–Ciocalteu method). Sampling was conducted in Palu Bay, Central Sulawesi, Indonesia. Based on monomorphic colonies and sclerites, soft coral samples were identified as Sinularia gibberosa. The chemical profiles of S. gibberosa extracts was dominated by trimethylethanolamine (22.03%), arachidonic acid (14.13%), (3R)-3-hydroxy-4-(trimethylazaniumyl)-butanoate (10.90%), (5Z,8Z,11Z,14Z,16R)-16-Hydroxy-5,8,11,14-icosatetraenoic acid (5.64%), Octyl decyl phthalate (4.18%), and N-Methylnicotinic acid (3.63%). The antibacterial assaying at 300 mg/mL of S. gibberosa extracts showed moderate to strong antibacterial activity, with the inhibition zone diameter of L. monocytogenes (15.11 ± 0.70 mm), P. aeruginosa (13.44 ± 0.84 mm), and S. typhimurium (19.78 ± 0.39 mm). S. gibberosa extracts showed strong antioxidant activity, with an IC50 of 54.69 ± 0.34 µg/mL and total phenolic content was 5423.76 ± 14.00 mg GAE/25 mg dry extract. Based on the results, S. gibberosa shows the potential for antibacterial and antioxidant activity. This study indicates that soft corals origin Palu Bay, Central Sulawesi, Indonesia, are potential organisms in the discovery and development of antibacterial and antioxidant agents.
