The cultivation of vaname shrimp produces waste with a high nutrient content. This waste can be used as fertilizer in microalgae culture like Sprulina platensis. However, the N / P ratio in shrimp culture waste is low, namely 5.5: 1, while the need for growth of blue-green algae ranges from 10:1 - 16:1. Therefore, it is necessary to regulate the N: P ratio in shrimp culture waste to match the needs of S. platensis. The purpose of this study was to determine the effect of different N / P ratios on shrimp culture waste fertilizer on the growth of S. plantesis. This study used a Completely Randomized Design (CRD) which was divided into 6 treatments with 3 replications, as P0: Walne fertilizer (N / P ratio 17: 1), P1: shrimp culture waste fertilizer enriched with urea (N / P ratio 5,5: 1), P2 with N/P ratio of 10.5: 1, P3 with N/P ratio of 15.5: 1, P4 with N/P ratio of 20.5: 1 and P5 with N/P ratio 25.5: 1. The parameters observed were density and growth rate of S. platensis and water quality namely: temperature, salinity, and pH. The data obtained were processed using Analysis of Variance (ANOVA) and continued with Duncan's multiple range test. The results of this study indicate that the application of shrimp culture waste fertilizer with different N/P ratios affect the population and growth rate of S. platensis. Shrimp culture waste fertilizer with a N: P ratio of 15.5: 1 (P3) is the best treatment for the growth of S. platensis because it produces the highest population and growth rate compared to the other treatments.

Moina macrocopa is a natural food that has the potential for freshwater fish seeds, because of its high nutritional value, easy to digest and has a fast, fast breeding, and has a size that is in accordance with the fish's mouth opening. Problems in the use of M. macrocopa as natural food are constrained by the availability of M. macrocopa both from nature and from cultivation. Population density in M. macrocopa cultivation varies due to different quality of food used. The needs of M. macrocopa as natural food can be met if the quality and quantity of feed used optimally support population growth. This study aims to determine the effect of lemuru fish oil concentration in bran suspension fermentation on fecundity and offspring production of M. macrocopa. This study used a completely randomized design (CRD) consisting of five treatments three replications, namely: control treatment (0 mg/L lemuru fish oil, 100 gram bran), P1 (4 mg/L lemuru fish oil, 100 gram bran), P2 (lemuru fish oil 5 mg/L, 100 gram bran ), P3 (lemuru fish oil 6 mg/L, 100 gram bran), P4 (7 mg/L lemuru fish oil, 100 grams), and P5 (8 mg/L lemuru fish oil, 100 gram bran ).The parameters observed were fecundity and child production per parent and water quality. Data analysis used the Analysis of Variance test followed by Duncan's multiple test. The results showed that the cultivation of M. macrocopa using different bran suspension feed with supplemented lemuru fish oil affected the fecundity and production of children per M. macrocopa parent. The concentration of lemuru fish oil of 6 mg/L in the feed resulted in a fecundity of 24,00±2,00 eggs/parent and child production is 20,33±1,52 ind/parent.

Textile waste consists of insoluble solid particles, salts, dyes and heavy metals and is very difficult to degrade. Chitin derived from shrimp waste has the potential to overcome textile waste in chitin that causes environmental pollution through more economical absorption and easily available raw materials. Factors that improve adsorption performance include pH and temperature. This study was conducted to determine the effect of temperature, pH, and a combination of temperature and pH treatments on the ability of chitin to adsorb textile dye waste. The parameters observed were temperature, pH, combination of temperature and pH, functional groups (FTIR), chitin structure (SEM), and heavy metal test (AAS). Data analysis of statistical test results using two-way Analysis of Variance (ANOVA) followed by Duncan's further test. The ANOVA test results showed that the incubation treatment of temperature, pH, and a combination of different temperature and pH treatments resulted in (p < 0.05). This shows that incubation temperature and pH have an effect (significantly different) on the adsorption of chitin as an adsorbent on dyes. The results of Duncan's test showed that the best chitin adsorption was obtained in temperature incubation at 50°C (A3), incubation at pH 3 (B1), and the best combination adsorption at 50°C and pH 3 of 1,091±0.007a ppm.

Carbon dioxide emissions from burning fuel oil have been increasing, resulting in increasingly severe climate change. The use of microalgae as raw materials for biofuel production is an environmentally friendly alternative. Microalgae Chlorella sp. can be sustainably converted into alternative biofuels. Fishery liquid waste, such as that resulting from fish farming and fish processing, can be used as a nutrient medium for microalgae. This study aimed to analyze biomass production from Chlorella sp. using fishery waste in an algae reactor. The working principle of fisheries wastewater processing is related to microalgae in the reactor. The surface of the media forms a biological layer that breaks down organic compounds in the air, thereby reducing the organic content. The compounds resulting from metabolic processes are in the form of solids and gases. The results show that the bioethanol produced from the thermostat Chlorella sp. with fishery waste media can produce 20,000 L/ha. Microalgae contain approximately 20-50% dry weight of carbohydrates, which can be converted into bioethanol. Chlorella sp. can reduce chemical oxygen demand and ammonia by up to 70% by converting carbon dioxide into carbohydrates, fats, and proteins. The application of bioconversion to all companies in the fisheries sector will provide benefits and help the government reduce fossil fuel subsidies.

Collagen extraction with high acetic acid can affect the characterization and damage the collagen structure, which then affects the level of temperature stability in collagen, so a combination method is needed to reduce the use of acetic acid in collagen extraction. Collagen extraction with a combination method with ultrasonication is more efficient and can help with these problems. Extraction of catfish skin collagen using a combination of acetic acid concentration and ultrasonication time can accelerate collagen extraction, reduce the use of acetic acid, and improve collagen structure. The aim of this study is to assess the potential of catfish (Pangasius hypophthalmus) skin as a nano collagen source through the combination of extraction time variation and acetic acid concentration under ultrasonication treatment. This study used a completely randomized design (CRD). Preparation of catfish skin collagen using acetic acid solvents with concentrations of 0.1 M and 0.2 M with ultrasonication times of 150 minutes and 200 minutes in four treatments with three repetitions. Analysis of statistical test data using Analysis of Variance (ANOVA) followed by Tukey's test. The results of this study indicate that the combination of varying acetic acid concentrations and ultrasonication times has a significant effect (P<0.05) on the collagen yield parameters from catfish skin. The highest yield was obtained with the treatment of 0.2 M acetic acid and 200 minutes of extraction time, resulting in a wet collagen yield of 85.18% and a dried collagen yield of 1.75%. The amino acid content consisted of 23.96% glycine and 17.40% proline. These findings demonstrate that catfish skin (P. hypophthalmus) has the potential to be developed as a raw material for nanocollagen development through variations in extraction time and acetic acid concentration using the ultrasonication method.

Generally, collagen is isolated using acid, base and enzymatic hydrolysis methods. However, this has the constraint of the length of time for the release of procollagen to produce collagen. Acetic acid hydrolysis combined with the hydroextraction method is one alternative to produce quality collagen. The use of acetic acid in the extraction of red snapper scales (Lutjanus malabaricus) will produce H+ ions to release procollagen in the raw material. The study aims to evaluate the potential of red snapper (L. malabaricus) scales as a collagen source through the hydroextraction method for the development of nanocollagen formulations. This study used a completely randomized design (CRD). Isolation of red snapper scales collagen using acetic acid solvent concentrations of 1 M; 1.5 M and 2 M with a hydrolysis time of 2 hours and hydroextraction for 2 hours with three repetitions. The parameters observed in this study were the proximate of collagen raw materials, collagen yield, and collagen amino acids. The data analysis results were tested statistically using Analysis of Variance (ANOVA) followed by Tukey's further test. The best result of collagen isolation from red snapper (L. malabaricus) scales was achieved using 2 M acetic acid hydrolysis combined with hydroextraction. This study demonstrated that the combination of different acetic acid concentrations with hydroextraction had a significant effect (P<0.05) on collagen yield parameters. The amino acid content consisted of 22.37% glycine and 12.45% proline. These findings indicate that red snapper (L. malabaricus) scales have the potential to be developed as a raw material for nanocollagen developments.

The phenomenon of stunting has caught global attention as it may disrupt children growth and development which is important for national sakes. This problem also occurred on the community of Putat Jaya Barat, Surabaya. Despite the decrease of stunting prevalence on 2022 by 21.6%, the community of Surabaya should maintain their awareness to prevent the occurrence of stunting near in the future. Therefore, in order to prevent the occurrence of stunting, it is necessary to provide community service which is related to the introductory of protein isolate-based products from fisheries commodities. Protein isolate as a functional food has concentrated protein content which may fulfil daily consumption need. This community service activity was conducted to provide participants with the knowledge of stunting phenomenon, fisheries product diversification, and the demonstration on isolate protein production method. The result of this this community service activity showed that the participants were poorly informed with the stunting information, however the participants were still able to provide their family with adequate food consumption based on the concept of “4 Sehat 5 Sempurna”. The participants were also provided with the understanding toward fisheries product diversification. The questionnaires evaluation showed that the participants need further assistance related to the application of protein isolate on fisheries products, with the nutritional information, and healthy life socialization.

Gonadal maturity and spawning of Siamese striped catfish depend on the rainy season, while outside of the season, hormonal treatment is not effective. Alternative technologies should be explored to enhance the gonadal maturity of fish. This study aims to examine the effect of infrared soft-laser irradiation on the gonadal maturity stage (GMS) of female Siamese striped catfish (Pangasianodon hypophthalmus). This study was performed through experimental methods using a completely randomized design (CRD) consisting of six treatments with four replications. Treatments were used, namely negative control (K-, no treatment), positive control (K+, injection of human chorionic gonadotropin / hCG and ovaprimTM), soft-laser exposure dose of 0.2 J/cm2 (T1), 0.4 J/cm2 (T2), 0.6 J/cm2 (T3), and 0.8 J/cm2 (T4). The parameter of GMS was measured. Data was analyzed using ANOVA following Duncan’s multiple range test. The result showed that soft-laser irradiation showed significant differences (P < 0.05) in GMS of female Siamese striped catfish. The highest GMS was shown through soft-laser exposure dose of 0.4 J/cm2 (T2), with 98.75% of fish reaching GMS IV and 1.25% at GMS III. Infrared soft-laser irradiation dose of 0.4 J/cm2 was the optimal dose to accelerate the gonadal maturity of female Siamese striped catfish.
