FISHERIES PRODUCT SPOILED MONITORING USING SMART PACKAGING CONTAIN ANTHOCYANIN: A REVIEW
Full text linkSmart packaging is currently demanded to monitor the spoilage level of packaged products, for instance fishery products, characterized as perishable food. Smart packaging requires a halochromic substance, for instance, natural pigments extracted from fruits or flower. The natural pigment extracted from the plant should have a halochromic ability for example anthocyanins compound. Anthocyanin compounds are incorporated to edible film to produce smart film. The smart film has the ability to screen the quality and to monitor freshness of fishery products by demonstrating color changes from purple or blue to green and then yellow color after being exposed to spoiled conditions. The color changes are induced by changes of pH and TVB-N production in deteriorated of packaged fishery products. Moreover, smart packaging is able to provide real-time information to consumers regarding product freshness, thus enhancing the safety and maintaining the quality of food products. In addition, the advantages of a smart packaging system include simple and inexpensive production, providing "best before" information, and potentially reducing unnecessary food wastePengemasan cerdas saat ini dituntut untuk memantau kesegaran produk yang dikemas seperti produk perikanan yang bercirikan sebagai pangan yang mudah rusak. Kemasan cerdas memerlukan zat halokromik, misalnya pigmen alami yang diekstraksi dari buah atau bunga. Pigmen alami yang diekstrak dari tumbuhan harus mempunyai kemampuan halokromik misalnya senyawa antosianin. Senyawa antosianin ditambahkan ke dalam film yang dapat dimakan (edible film) untuk menghasilkan film pintar (smart film). Smart film ini mempunyai kemampuan untuk memantau kualitas dan kesegaran produk perikanan dengan menunjukkan perubahan warna dari ungu atau biru menjadi hijau dan kemudian menjadi kuning setelah terkena kondisi pangan yg rusak. Perubahan warna tersebut disebabkan oleh perubahan pH dan produksi TVB-N pada produk perikanan kemasan yang telah rusak. Selain itu, smart packaging mampu memberikan informasi real-time kepada konsumen mengenai kesegaran produk, sehingga meningkatkan keamanan dan kualitas produk pangan. Selain itu, keunggulan sistem pengemasan cerdas antara lain produksi yang sederhana dan murah, memberikan informasi “baik sebelum”, dan berpotensi mengurangi limbah makanan yang tidak diperluka

IDENTIFICATION OF THE TEMPORAL RELATIONSHIP BETWEEN THERMAL FRONT INTENSITY AND SKIPJACK FISHERIES PRODUCTION LANDED AT PPN TERNATE
Full text linkThe convergence of two oceans in Indonesian waters results in complex oceanographic dynamics, including the formation of thermal fronts. Thermal front areas are rich in nutrients, making them valuable for predicting potential fishing grounds. This study aims to identify the relationship between thermal fronts and skipjack tuna fisheries production landed at PPN Ternate, in order to assess whether thermal front data can be used to predict skipjack tuna fishing grounds in the area. The data utilized consists of fisheries production records and sea surface temperature images obtained from the Terra MODIS satellite. The images were processed using the Single Image Edge Detection (SIED) algorithm to map thermal front areas and measure their intensity. The relationship between thermal front intensity and skipjack tuna production was analyzed using Pearson correlation. The results show that thermal front areas are dynamically distributed around PPN Ternate every month, with increased intensity observed in February-March, July-October, and December. However, Pearson correlation analysis indicates no significant relationship between thermal front intensity and skipjack tuna fisheries production.The convergence of two oceans in Indonesian waters results in complex oceanographic dynamics, including the formation of thermal fronts.

ANALYSIS OF WATER QUALITY BASED ON COMPOSITION AND ABUDANCE OF PHYTOPLANKTON IN RASAU JAYA RIVER
Full text linkPengaruh Pemberian Ekstrak Kulit Jengkol pada Pakan Terhadap Profil Darah Ikan Patin Siam (Pangasius hypophthalmus)
Full text linkPathogenic bacteria are one of the main challenges in the cultivation of Pangasianodon hypophthalmus because they can cause organ damage and even death. The utilisation of natural ingredients such as Archidendron pauciflorum peel extract is one alternative to improve fish health in an environmentally friendly manner. This study aimed to evaluate the effect of adding Archidendron pauciflorum peel extract in feed on haematological parameters of Pangasianodon hypophthalmus. A total of 160 test fish were divided into four treatments with extract doses of 0% (control), 0.01%, 0.02%, and 0.03%, for 21 days. Parameters observed included total erythrocytes, haemoglobin levels, and haematocrit values. The results showed that Archidendron pauciflorum peel extract significantly increased haemoglobin levels and haematocrit values (P<0.05), especially at the 0.03% dose, compared to the control. Total erythrocytes showed a decrease on day 21 in all extract treatments, presumably due to the content of bioactive compounds (tannins, flavonoids, and saponins) in high doses. Bioactive compounds in Archidendron pauciflorum peel extract such as flavonoids, saponins, and tannins are known to play a role in improving haematological parameters, but their use needs to pay attention to the appropriate dose so as not to cause negative effects.
Bakteri patogen merupakan salah satu tantangan utama dalam budidaya ikan patin siam (Pangasianodon hypophthalmus) karena dapat menyebabkan kerusakan organ hingga kematian. Pemanfaatan bahan alami seperti ekstrak kulit jengkol (Archidendron pauciflorum) merupakan salah satu alternatif untuk meningkatkan kesehatan ikan secara ramah lingkungan. Penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan ekstrak kulit jengkol dalam pakan terhadap parameter hematologi ikan patin siam. Sebanyak 160 ekor ikan uji dibagi ke dalam empat perlakuan dengan dosis ekstrak 0% (kontrol), 0,01%, 0,02%, dan 0,03%, selama 21 hari. Parameter yang diamati meliputi total eritrosit, kadar hemoglobin, dan nilai hematokrit. Hasil penelitian menunjukkan bahwa pemberian ekstrak kulit jengkol meningkatkan kadar hemoglobin dan nilai hematokrit secara signifikan (P<0,05), terutama pada dosis 0,03%, dibandingkan dengan kontrol. Total eritrosit menunjukkan penurunan pada hari ke-21 pada semua perlakuan ekstrak, diduga akibat kandungan senyawa bioaktif (tanin, flavonoid, dan saponin) dalam dosis tinggi. Senyawa bioaktif dalam ekstrak kulit jengkol seperti flavonoid, saponin, dan tanin diketahui berperan dalam peningkatan parameter hematologi, namun penggunaannya perlu memperhatikan dosis yang sesuai sehingga tidak menimbulkan efek negatif.
