<![CDATA[Snakehead fish fillet is a perishable food product, caused by microbial activity. The way to overcome the damage is by preservation. Preservation using antimicrobial substrate from lactic acid bacteria is safe for health and inhibits the growth of rotting bacteria and pathogens in foodstuffs. This research has been carried out on the application of antimicrobial substrate from Pediococcus pentosaceus BAF715 preservation of fish fillets, stored at chilling temperatures. for 12 days. This study used a completely randomized design with 7 treatments and 3 replications and statistical analysis was carried out on the observed variables: pH, total bacteria, Escherichia coli, Staphilococcus aureus and Salmonella sp. The results of the analysis showed that after 8 days of storage there was an increase in pH, total microbes and S. aureus, but during storage there was no presence of E. coli and Salmonella. The microbiological quality of snakehead fish fillets preserved with antimicrobial substrate from Pediococcus pentosaceus BAF 715 stored at chilling temperature can be maintained for up to 8 days]]>

<![CDATA[The sea boundary is an authority in managing marine environmental resources that aim to limit each local government's management. The Indonesian government has made various regulations in regulating regional boundaries, including maritime boundaries. This study aims to determine the differences in the determination of sea boundaries that have been regulated in the Permendagri, including Permendagri No. 1 of 2006, Permendagri No. 76 of 2012, and Permendagri No. 141 of 2017. This research is limited to the study of literature articles that regulate the determination of the boundaries of marine areas. Permendagri No.1 of 2006 and Permendagri No. 76 of 2012 explained that the authority over the management of marine resources is managed by the regions. While in Permendagri No. 141 of 2017 explained that the management of marine resources is regulated by law. The study results found that three critical points of change are listed in the Permendagri, including the use of base points, the use of cartometric methods, and the authority of sea management by districts/cities. From this research, it can be concluded that the Regency/City no longer has the authority to manage marine resources. However, the affirmation of the 4-mile sea boundary for the Regency/City is still needed to calculate the profit-sharing for the management of marine resources. Determination of the base point in the affirmation of boundaries no longer uses the lowest low tide but uses the highest tide as stated in Permendagri No. 141 of 2017. The affirmation of maritime boundaries using the cartometric method has begun to be applied to Permendagri No. 76 of 2012 and continued in Permendagri No. 141 of 2017.]]>

<![CDATA[The low level of welfare of small fishermen is a problem that still cannot be solved. To get an overview of changes in fishermen's welfare quickly, an instrument that is easy to use and can fully describe the welfare of fishermen is needed. The fisherman's exchange rate can be used as an indicator based on the KKP guidelines in measuring the welfare of fishermen. Pekalongan City is one of the coastal areas with high resource potential, especially in the fisheries sector. One of the fishing ports in Pekalongan City is Pekalongan NFP, where the majority of fishermen are still classified as small fishermen. The picture of fishermen's welfare is closely related to the socio-economic conditions in the area. This study aims to determine the factors that influence the fisherman's exchange rate as an indicator of the welfare of artisanal fishermen in the NFP (Nusantara Fisheries Port) Pekalongan. The data used in this study are primary data and secondary data. Primary data were collected through questionnaires to respondents. Secondary data were collected through the desk study method in journals, articles, and books related to this research. The sampling technique used is purposive sampling where 159 people are taken as samples, the number of samples then becomes 130 people due to the elimination of outlier data as many as 29 people. Data analysis was performed using descriptive methods and multiple linear regression. Based on regression analysis, the results of this study found that age, education, total income, and total expenditure are factors that affect artisanal NTN in NFP Pekalongan.]]>

<![CDATA[Karangantu Archipelago Fishing Port (PPN Karangantu) is one centre of fishery activity in Banten Province with various socio-cultural backgrounds of fishermen. One of the factors that influence the design characteristics (hull form) of fishing vessels is related to the socio-cultural community. Therefore, it is necessary to study the characteristics of the traditional ship design (<5GT) operating in PPN Karangantu. The research was conducted in August-October 2018 at PPN Karangantu. Data was collected using survey methods, field observations and interviews. The number of samples used as many as 25 units of fishing vessel with consideration of size, type of fishing gear, and ship design. Data analysis was carried out in a descriptive comparative method. The results showed that ships with a size of <5GT were a group of static gear and towed/dragged gear. There are two transversely hull forms, namely U bottom and round bottom. As for the longitudinally hull shape, it consists of a transom shape (type A and type B) and double pointed.]]>

<![CDATA[Oral consumption of glucosamine hydrochloride can worsen side effects in the human body, so the development of nanoparticles from glucosamine hydrochloride is needed as a topical preparation in treating osteoarthritis. This study aims to determine the differences in the characteristics of nanoparticles from shrimp shell glucosamine made ultrasonic and ball milling. For the production of glucosamine from shrimp shells, the acid hydrolysis method was used using 37% HCL solution, then washed with IPA solution until glucosamine powder was formed, then the yield and FTIR tests were carried out. Preparation of glucosamine nanoparticles using the ultrasonic method, namely glucosamine with a 37% HCl mixture sonicated using an ultrasonicator, and another method using a ball mill to fission glucosamine to obtain powdered glucosamine nanoparticles. The powder obtained from the two methods was then characterized using a scanning electron microscope (SEM) to determine the morphological condition of the solid. The results of the glucosamine test obtained a yield of 83.65%, and the absorption pattern of the Fourier transform infrared (FTIR) spectrum showed 99.82% so that it met the quality standards proving that glucosamine hydrolysis was successful. The powder characterization obtained by SEM aims to determine the size characteristics of the glucosamine nanoparticles obtained. The resulting powder nanoparticles are yellow-white. The SEM photo results show the morphology of the particles with an uneven surface. The results of the Scanning Electron Microscope (SEM) test showed that the particle size of glucosamine by ultrasonic and ball milling methods were 83.56 nm and 61.16 nm, respectively.]]>

<![CDATA[Teknologi biofok merupakan metode pemeliharaan ikan dengan sedikit ganti air dan mengembangkan kongklomerat mikroba sebagai pakan ikan Namun penelitian tentang bioflok sebagai pakan tambahan yang diberikan dari luar sistem budidaya belum banyak dilakukan. Tujuan penelitian ini menganalisis pengaruh pemberian bioflok sebagai pakan tambahan terhadap performa produksi. Percobaan rancangan acak lengkap, dengan 4 perlakuan yaitu diberi pakan tambahan bioflok 240 ml (B240), diberi pakan tambahan bioflok 160 ml (B160), diberi pakan tambahan bioflok 80 ml (B80), dan tidak diberi pakan tambahan (NB), masing-masing perlakuan dengan 3 ulangan. Pakan bioflok diberikan satu kali sehari pada siang hari. Pakan pelet diberikan 4 % per hari dari total biomas ikan. Hasil penelitian menunjukkan suhu, pH dan oksigen terlarut masih dalam rentang yang layak bagi pertumbuhan lele. Jenis plankton di usus lele lebih banyak pada kolam bioflok dibanding kolam kontrol. Pertumbuhan biomas lebih tinggi dan konversi pakan lebih rendah pada B240 dibanding kontrol. Berdasarkan data penelitian dapat disimpulkan bahwa plankton yang ditemukan di usus ikan, menunjukkan bioflok yang diberikan ke kolam percobaan dikonsumsi oleh ikan lele. Bioflok yang diberikan di kolam mampu meningkatkan penambahan biomass dan menurunkan konversi pakan. Oleh karena itu dari hasil penelitian ini pembudidaya ikan dapat memanfaatkan bioflok sebagai nutrisi tambahan bagi ikan.]]>

<![CDATA[Koi Herpesvirus (KHV) is one of the viral fish disease in the common carp aquaculture. At present, KHV diagnoses is performed using Polymerase Chain Reaction (PCR) method. However, the effort to extract DNA viruses from environmental samples depends on two fundamental problems: inhibition of the extraction and amplification processes and a very small number of viruses. The small amount of virus load in the water requires a concentration process before further molecular analysis. In this study, the sensitivity of three methods of extraction and purification of viral genetic material from the water, namely deposition with PEG, filtration-elution, and flocculation with antibodies for the detection of KHV from the water with the PCR method was performed. Water samples were collected from Cirata reservoir, West Java which is a site location for carp aquaculture. The organic flocculation cannot be carried out in the present study because anti-KHV antibodies cannot be produced. This is because the amount of virus in the sample used by the vaccine is low. Meanwhile, the precipitation method with PEG cannot produce DNAextract’s although quantity and purity are good enough to be amplified. For the filtration-elution method, both with and without the reconcentration process, a clear band of DNA can be produced after amplification. In conclusion, the filtration-elution method is considered as the most suitable method in obtaining KHV DNA’s taken from the water samples.]]>
