The demand for grouper fish continues to increase, with the Ministry of Fisheries' annual production target 9,000 tons. However, intensive cultivation systems pose risks due poor water quality, making susceptible disease and health problems. This study investigated impact Trichodina sp. infection on blood glucose levels hybrid fish. was conducted in May 2024 by observing 30 measuring glucose. results showed that 20 above normal range (> 57.6 mg/dL), ranging from 61 114 mg/dL. In contrast,...

Abstract The carrageenan industrial waste materials can be used bioplastic biodegradable production because has high cellulose content 71.38%. Bioplastics easily degraded and flexible, it is necessary to add glycerol plasticizers, that reduce internal hydrogen in intermolecular bonds affected biodegradability mechanical properties of bioplastics. This study aimed was analyze the effect application as plasticizers on bioplastics based analysis best concentration get biodegradation standards...

Abstract An additional ingredient is needed in making bioplastics to increase the elasticity value, namely plasticizer Polyethylene Glycol 400. This study aims determine effect of application (PeG) 400 as a cellulose-based from carrageenan-making waste biodegradability and best concentration on its mechanical properties. activity was carried out January March 2020 Laboratory Chemical Analysis Faculty Fisheries Marine Airlangga University. Data collected by an experimental method that direct...

Abstract The objectives of this research were: 1) determine the effect fermented rice bran suspension concentration on fecundity and production M. macrocopa offspring per parent, 2) optimal parent. This used an experimental method with a completely randomized design consisting six treatments without fermentation (P0), 19.54 mg / L (P1), 21.98 (P2), 24.42 (P3), 26.68 (P4) 29.30 (P5) in four replications for each. results culture different showed significant difference (P <0.05) highest...

Abstract Synthetic plastic waste is the cause of environmental pollution. Therefore, innovation needed in manufacture plastics using renewable raw materials, namely bioplastics. Bioplastics can be made from carrageenan industrial because they have high cellulose content. it necessary to add sorbitol plasticizer affect biodegradability and mechanical properties. This study aimed was determine effect concentration synthesis bioplastics cellulose-based on too determined best geet biodegradation...

Kuhli loach (Pangio kuhlii) a popular ornamental freshwater fish species with economic potential, originating from Sumatra, Kalimantan, Java, and Malaysia. The kuhli loach's appeal lies in its vibrant colors distinctive eel-like body. This study aims to explores the sexual primary secondary characteristics of loach. Conducted at Universitas Airlangga Banyuwangi, Indonesia, involved thorough analysis 50 loaches, evenly split between males females. Morphological observations revealed...

Initially, the use of Additive Manufacturing (AM) technology is mainly for production prototypes a new invention and design. However, AM had extended to tooling industry, medical scaffolding, direct part production. This due extensive research development carried out around globe regardless material, equipment, AM. In this study, characterization properties PCL/PLA/PEG/Nano-HA polymer composites were investigated. Polycaprolactone (PCL), polylactic acid (PLA), polyethylene glycol (PEG),...

Abstract Dissolved oxygen is the parameters key of water quality. Low level dissolved can affect function and slow growth, even cause death to fish in hypoxia condition. The aims this experiment were determine effect population density Daphnia spp. concentration correlation between with color scoring This method was experimental Completely Randomized Design as design 6 treatments 4 replications. treatment that given differences consisted A (50 individu/200 ml), B (250 C (450 D (650 E (850 F...

Abstract Gracilaria sp. contains macro and micronutrients needed by plants, such as phosphorus, potassium, calcium, magnesium, manganese, zinc, boron. Seaweed-based liquid organic fertilizer currently on the market has low phosphorus potassium content. One ingredient that can increase content is fishbone.
