The fish farming business in Pangkalpinang City is growing along with the increasing demand for aquaculture products. Sangriang Farm is a fish farming business engaged in the hatchery and rearing of Gurame ( Osphronemus goramy ), Catfish ( pangasius sp .), Goldfish ( Cyprinus carpio ), Tilapia ( Oreochromis niloticus ), and Catfish ( Clarias sp .). This study aims to analyze existing business models and recommend new business models through the Business Model Canvas (BMC). The research method used in this study is a survey method with a case study technique. Analysis of existing conditions reinforced by SWOT analysis resulted in BMC improvements in Channels elements (use of social media, product labels, and packaging), Key Resources (additional human resources, capital, and intensification of cultivation technology), Customer Segments (target consumers of semi-finished processed products and restaurant suppliers), and Revenue Streams (bookkeeping management and product diversification). Implementing the recommendations is expected to increase the business capacity of Sangriang Farm.

The aquaculture field continues to grow from year to year. This is because aquaculture fulfills the world's food needs. Aquaculture intensification continues. As a result of this intensification, the aquaculture environment experienced a decrease in water quality. This led to the rapid growth of bacteria, fungi, parasites, and viruses, resulting in a high incidence of disease outbreaks. An alternative solution that has been extensively researched recently is using immunostimulants to increase the non-specific immunity of fish and shrimp, which will help fish and insects prevent disease outbreaks. One of the natural ingredients that have the potential to become an immunostimulant is from the brown algae group. Immunostimulants from brown algae such as Hot-water Extract of Tropical Brown Seaweed, Sargassum cristaefolium, Sargassum glaucescens, Sargassum duplicatum, Sargassum wightii, Sargassum sp. Polysaccharides from seaweed, such as fucoidan extracts from brown algae, can enhance the non-specific immune system in shrimp Litopenaneus vannamei, Penaeus monodon, Fenneropenaeus indicus, and tilapia Oreochromis niloticus. These immunostimulants increase non-specific immunity, such as total hemocyte count, phagocytosis activity, phenoloxidase, phagocytic, respiratory burst, superoxide dismutase, and total plasma protein. Immunostimulants from brown algae can also fight bacterial disease attacks Vibrio parahaemolyticus, Streptococciasis, Streptococcus iniae, and White spot syndrome virus (WSSV) by increasing survival rate and can increase the growth and feed efficiency of cultivated commodities that are not given immunostimulants.

Vanamei shrimp Litopeneus vannamei is a commodity with high economic value. Shrimp is Indonesia's main export commodity. The high value of sales and production of vanamei shrimp is constrained by the many disease attacks in the vanamei shrimp farming industry. An alternative solution that has been continuously researched for several years to combat shrimp disease is using immunostimulants from natural ingredients. Using natural ingredients for immunostimulants can increase the non-specific immunity of vanamei shrimp to ward off disease and be environmentally friendly. Immunostimulants can be administered orally, by immersion, or by injection. Immunostimulants from natural ingredients such as spirulina platensis, polysaccharides from seaweed such as carrageenan, sodium alginate, and fucoidan, extracts from red seaweed, as well as the use of polysaccharides from the bacterium Nodulisporium sp.

Vannamei shrimp is a shrimp that has high economic value in Indonesia. The poor aquatic environment can reduce shrimp growth rates and stress and cause death, and efforts to improve water quality by giving Probiotics EM4. Probiotic EM4 contains beneficial bacteria that can improve shrimp's digestive system, decompose organic matter in the waters, control the growth of pathogenic bacteria, and improve water quality. The experimental parameters included total hemocyte count (THC), differential hemocyte count (DHC) consisting of hyaline cells, granule cells, and semi-granule cells, and phagocytic activity (AF). The study was carried out for 69 days using vanamei shrimp with PL 30. This study used four treatments and three replications, namely treatment P0 (without giving probiotic EM4), P1 (giving probiotic EM4 at a dose of 0.5 ml/L), P2 (giving probiotic EM4 at a dose of 1.5 ml/ L), P3 (giving probiotic EM4 dose of 2.5 ml/L). The study's results proved that the administration of probiotic EM4 on the maintenance medium had a significant effect (P<0.05) on THC, DHC, and AF. At THC, the highest value was at P3 with a value of 19.44 x 10 6 cells/ml, and the lowest was at P0 with a value of 11.01 x 10 6 cells/ml, then the DHC values such as hyaline cells ranged from 51.34 – 65.81%, granule cells ranged from 21.33 – 30.4%, semi-granular cells ranged from 12.84 – 18.24%. And then for the highest AF value at P3 with a value of 67.97% and the lowest P0 with a value of 49.34%

Aeromonas hydrophila is a bacterium that causes MAS disease (Motile Aeromonas Septicemia), often found by cultivators. This study aimed to determine the effectiveness of onion extract (Allium cepa L.) in replacing chemical antibiotics and the correct dosage to inhibit the growth of Aeromonas hydrophila bacteria in vitro. The research method used was a Completely Randomized Design (CRD) with 7 treatments and 3 replications, P1 (Control-), P2 (Control+), P3 (10% onion extract), P4 (25% onion extract), P5 (50% onion extract), P6 (75% onion extract), P7 (100% onion extract). The results showed that 30 ml of onion extract obtained from 101.3 grams of onion powder had a yield value of 29.812%. Some secondary metabolite compounds in onion extract are flavonoids, alkaloids, saponins, tannins, steroids, and phenols, which function as antibacterial compounds. The diameter of the clear zone of 10% onion extract has a value of 26 mm and has a value that is not significantly different from the use of 50% chloramphenicol antibiotics with an inhibition zone diameter of 26.67 mm, treatment with onion extract with a concentration of 100% gives the same inhibition zone diameter. The highest is 34.17 mm.

The main problem in cultivation is a disease that causes less optimal growth and even death. This study aims to analyze the effectiveness of black cumin extract on the inhibition of A. hydrophila bacteria, analyze its active ingredients, analyze its toxicity level to Tilapia, and analyze the effect of the extract on the survival rate and morphology of Tilapia after being infected with A. hydrophila bacteria. The method used was a completely randomized design (CRD) which consisted of 3 stages. Inhibition zone with 5 treatments 2 repetitions, namely P0 (aquades), P1 (25%), P2 (50%), P3 (75%), and P4 (100%). LC50 with 4 treatments 2 replications using regression analysis with the help of the probit table. In Vivo with 6 treatments, 3 replicates, namely P0 (NaCl injection) as a control-, P1 (bacterial injection) as control+, P2 (250 ppm), P3 (500 ppm), P4 (750 ppm), P5 (1000 ppm). The results showed that black cumin seed extract with various concentrations affected the inhibition of A. hydrophila, SR, and Tilapia morphology after infection with bacteria. The test of inhibition with concentrations of 25%, 50%, 75%, and 100% can inhibit the growth of bacteria A. hydrophila because it contains antibacterial activity compounds. The extract has toxic properties to Tilapia (LC50=220.23 ppm). Soaking fish for 30 minutes in the I n Vivo test P3 treatment is the best treatment because it can provide a high SR of 73.3 %. However, at high concentrations, it can reduce fish survival.

Pearl oysters are a marine aquaculture commodity with high economic value. However, there are still many obstacles in pearl oyster cultivation activities, such as the need for quality seeds. This study aims to determine the effect of immersing pearl seeds in natural feed tanks of Chaetocheros sp. with different immersion periods on the growth and survival rate of pearl oyster (Pinctada maxima) seeds. The method used in this study is an experimental method using a completely randomized design (CRD), with 5 treatments and 3 replications, namely A (control/without immersion), B (0.5 hours), C (1 hour), D (1, 5 Hours) and E (2 Hours). The results showed that soaking the seeds in natural feed tanks had a significant effect on the growth of the shell (dorsal-ventral) of the pearl oyster Pinctada maxima (p<0.05). The highest growth was achieved in the 2-hour immersion period with an absolute growth value of 1.67 mm, a relative growth of 68.49% from the initial size, and a daily specific growth rate of 3.31% per day. This method must be tested on larger pearl oyster seeds and using other natural feed species and various natural mixes (multi-species).

Seed is essential in aquaculture activities, but tilapia hatcheries often suffer from disease attacks caused by Aeromonas hydrophila bacteria, causing losses for hatchery businesses. One of the natural ingredients for treating Aeromonas hydrophila is betel leaf extract. This study aims to analyze the effect of betel leaf extract (Piper betle L.) on Aeromonas disease hydrophila on fish fry tilapia (Piper betle L.). This study used a completely randomized design (CRD) with 5 treatments and 3 replications. The treatment used was a dose of betel leaf extract (P1) 0.4 ml, (P2) 0.6 ml, (P3) 0.8 ml, (P4) positive control, (P5) negative control. The parameters observed were survival rate, specific growth rate, feed conversion ratio, absolute length growth, erythrocytes, hemoglobin, hematocrit, leukocytes, differential leukocytes, total bacteria count, and water quality. The results of this study showed that before and after the challenge test, the best average values were P3 leukocytes (1.06 and 1.4 x 10 5 ), erythrocytes (0.90 and 0.93 x 10 5 ), hemoglobin (10.9 and 9.7), hematocrit (10.7 and 10.3), total bacteria (7 x 10 1 ). Then the worst value on P1 leukocytes (0.74 and 0.87 x 10 5), erythrocytes (0.86 and 0.75 x 10 5 ), hemoglobin (10.7 and 7.7), hematocrit (10.3 and 9.3), total bacteria (74 x 10 2 ). The study concluded that the best treatment was found in treatment 3 with a dose of 0.8 ml of betel leaf extract, which significantly increased the immune system in tilapia seeds.

This study aims to determine tilapia's growth and immune system (Oreochromis niloticus) through feeding with added turmeric flour. This study used a completely randomized design with five treatments, namely K- (feed without adding turmeric flour and injected with physiological solution), K+ (feed without adding turmeric flour and injected with A. hydrophila bacteria), P1 (addition of turmeric flour 1 % / kg of feed + bacterial infection of A. hydrophilla), P2 (Addition of 2% turmeric flour/kg of feed + bacterial infection of A. hydrophilla), and P3 (Addition of 3% turmeric flour/kg of feed + bacterial infection of A. hydrophilla) each treatment had three replicates for a total of 15 trials. The results showed that there was a significant effect (p > 0.05) on growth but no significant effect (p < 0.05) on the survival of tilapia, so further tests were carried out to determine the best treatment in producing tilapia growth, it is known that P2 (Addition of 2% turmeric flour/kg of feed + bacterial infection of A. hydrophilla) is the best treatment in this study.

Dry noodles are a staple food item among Asian population. Generally, it contains a low-fat and a high-carbohydrate level, however it lacks other nutrients, such as protein and dietary fiber. The addition of spirulina into dry noodles may increase both protein and dietary fiber. The aim of this study was to determine the effect of spirulina fortified in the dry noodle on physico-chemical and sensory properties. The method used in this study was experimental with a completely randomized design (CRD) using 4 replications. The spirulina powders added into dry noodles were 0%, 4%, 4.5%, 5%, 5.5%, 6% and 6.5%. The results showed the addition of spirulina in dry noodles had a significant effect (p<0.05) on nutritional values, such as protein, fat, ash, carbohydrate and dietary fiber. In addition, physical properties of fortified noodles, including cooking loss, elongation and tensile strength were also significant differences. For sensory attributes, noodles fortified with different concentrations of spirulina showed significant effects in appearance, aroma, color, taste and texture. A selected dry noodle fortified with 6% of spirulina based on the physico-chemical and sensory characterization. The fortified dry noodle can contribute to improving nutritional profile that may be beneficial on health.
