The main ingredient of dry noodles is wheat flour which made from milling wheat. However, we usually obtain wheat from overseas by import. Therefore, to achieve food resilience in Indonesia, it is necessary to find substitutes for local ingredients with high nutrition that can be used to make dry noodles. This research aims to investigate the characteristics of dry noodles made from Kappaphycus alvarezii seaweed flour. The method used in this study was to substitute K. alvarezii seaweed flour as much as 0, 5, 10, 15, 20, and 25% in the production of dry noodles. Analysis was carried out on its chemical composition, physical properties, and organoleptic characteristics. The results showed the best result of substitution of K. alvarezii in the 5% treatment. The chemical composition in dry noodles of this treatment showed water content of 8.39%; ash content 3.07%; fat content 0.59%; protein content 12.43%; and 0.29% crude fiber content. Meanwhile, the results of the physical test showed7.95% cooking loss;210.5 seconds cooking time; and 89.34% water absorption. The organoleptic values obtained are color 4.60 (like); fragrance 4.80 (like); texture 4.23 (like); and taste 4.20 (like).
Milkfish satay processing has been left viscera waste that may causes environmental pollution. The viscera waste has contained omega-3 which can be extracted as fish oil. Dry rendering is a method of fish oil extracting using temperature without water addition. The temperature of extraction greatly affects to quality of fish oil. The purpose of this study was to determine the optimal temperature of extraction and characterized fish oil quality extracted from milkfish viscera. This study used dry rendering extraction methode with three different temperatures (40ºC, 50ºC, and 60ºC) and tested the yield, free fatty acids, peroxide value, p-anisidine and total oxidation, for the best fish oil will be tested for its fatty acid profile. The best treatment for extracting fish oil from milkfish viscera used extraction temperature of 50ºC with yield (6.88%), free fatty acid (4.89%) peroxide value (29.35 mEq/kg), anisidine value (4.61 mEq/kg), and total oxidation (63.53 mEq/kg). The fatty acid profile of fish oil was dominated by palmitic acid (31.17%) and also contains omega-3 such as linoleic acid, docosahexaenoate acid (DHA), and eicosapentaenoate acid (EPA).
Esomus metallicus merupakan spesies ikan yang secara alami tidak tersebar di Indonesia (non-native). Pada beberapa kasus, jenis ikan non-native telah mengancam ekosistem alami di perairan umum. Melalui ekspedisi ilmiah, dilakukan pengamatan yang bertujuan untuk mengkaji respons awal adaptasi pascapengangkutan, yaitu sintasan dan tingkah laku ikan E. metallicus liar di dalam wadah terkontrol. Selain itu, juga dilakukan analisis terhadap potensi pemanfaatan untuk bidang akuakultur, pengolahan hasil perikanan, dan strategi edukasi kepada masyarakat tentang ikan E. metallicus. Ekspedisi dilakukan selama dua hari di bagian barat Pulau Jawa. Ikan diangkut menggunakan sistem tertutup selama 6 jam. Pemeliharaan ikan pascapengangkutan dilakukan selama 14 hari. Hasil penelitian menunjukkan sintasan ikan E. metalicus selama pengangkutan yaitu 96,72%. Ikan E. metalicus dapat beradaptasi dengan baik di dalam wadah pemeliharaan terkontrol yang terlihat dari sintasan akhir pengamatan 90,96%, tingkah laku berenang yang aktif secara berkelompok dan telah memakan pakan buatan. Potensi sebagai ikan hias dapat dilihat pada warna sisik metalik, ukuran tubuh yang kecil, dan tingkah laku berenang berkelompok dapat menjadi ikan untuk akuaskap. Selain itu, potensi pemanfaatan ikan ini yaitu sebagai pakan hidup untuk ikan predator, tepung ikan, ikan uji di laboratorium, dan bahan makanan. Kajian lebih lanjut hal tersebut sebagai solusi pengendalian ikan non-native perlu dilakukan. Analisis risiko menunjukkan bahwa E. metallicus termasuk ke dalam spesies risiko sedang. Strategi edukasi terhadap masyarakat perlu dilakukan karena masyarakat menganggap ikan E. metallicus adalah “benteur” atau “paray”, yang merupakan nama lokal untuk ikan dari genus Rasbora asli Indonesia karena kemiripan morfologi.
