Water Quality Management in Enlargement Vannamei Shrimp (Litopenaeus vannamei) inPT. Bumi Harapan Jaya, Poto Tano, Sumbawa Barat
type: item
description: Shrimp is one of the main products of aquaculture in Indonesia. One type of shrimp that has high economic value compared to other types of shrimp is the vannamei shrimp (Litopenaeus vannamei). This type of shrimp is in great demand by cultivators because it can be cultivated intensively with high stocking densities and intensive feeding to achieve high production. Water quality management greatly determines the sustainability of the aquaculture industry because the development of shrimp culture through a high stocking density system and intensive feeding can cause problems such as a decrease in pond water quality for shrimp survival. The purpose of this study was to find out the correct methods and techniques for water quality management in growing vannamei shrimp (Litopenaeus vannamei) at PT. Bumi Harapan Jaya, Poto Tano, West Sumbawa. Data collection techniques used were primary and secondary through observation, direct observation, interviews and through journals, books, and related literature. Water quality management is divided into three parameters, namely physics, chemistry, and biology. The research results show that water quality values ​​for each physical, chemical, and biological parameter in the PT. Bumi Harapan Jaya ponds are still considered optimal. Water quality management at PT. Bumi Harapan Jaya's ponds begins with general water quality management, divided into several stages, including pond preparation, water sterilization, bacteria application, and routine monitoring of various water parameters

Efficacy of Nigella sativa Enrichment of Live Tubifex sp. to Enhance Larval Performance of Hemibagrus nemurus
type: item
description: The growth and survival of catfish larvae (Hemibagrus nemurus) are important factors in successful cultivation, which are greatly influenced by the quality of the natural feed provided. This study evaluated the effect of providing live feed Tubifex sp. enriched with Nigella sativa solution on the growth and survival of catfish larvae. Seven-day-old fish larvae were fed with various doses of Nigella sativa enrichment (0; 0.1; 0.2; 0.3; and 0.4 mg) for 21 days using a completely randomized design with three replications. The parameters observed included absolute weight, absolute length, specific growth rate, and survival. The results showed that Tubifex sp. feed enriched with Nigella sativa solution significantly increased all parameters of larval growth and survival, with the optimal dose at 0.2 mg. This increase is thought to be related to the content of the bioactive compound thymoquinone in Nigella sativa which functions as an antioxidant and immunostimulant, leading to increased metabolic capacity and resistance of larvae to environmental stress. This finding provides an innovative alternative to natural feed that is more nutritious and effective in cultivating catfish, while also supporting sustainable and environmentallyfriendly aquaculture practices.

Influencing Factors Analysis of Marine Tourism Demand in the Sanggar Beach Area, Tulungagung
type: item
description: Sanggar Beach in Tulungagung Regency has marine tourism potential based on its natural landscape, coastal beauty, and green turtle conservation value. However, limited accessibility, basic facilities, and safety risks hinder increasing tourism demand. This background necessitates a study of the factors influencing tourist interest. The purpose of this study is to analyze the variables influencing tourism demand to Sanggar Beach and formulate recommendations for sustainable destination management strategies. The research method was conducted through a field survey, interviews, and questionnaires distributed to 30 tourists using a purposive sampling technique. Data were analyzed quantitatively using multiple linear regression, complemented by descriptive analysis of tourist characteristics and the condition of attractions, accessibility, and amenities. The results indicate that the majority of tourists are young (15–25 years old), have a high school or bachelor's degree, have low to middle incomes, and are predominantly private sector workers and students. The regression analysis showed a very strong relationship (R = 0.90) with an R² = 0.80, meaning that 80% of the variation in tourism demand can be explained by the research variables. Simultaneously, independent variables significantly influence demand, although partially no significant effect was found at the 5% level, except for age, which approached significance (p = 0.0531). Facility evaluations show that attractions are excellent, the turtle hatchery is quite good, road access is considered poor, while amenities are mostly adequate but need improvement, especially the gazebo. In conclusion, tourism demand to Sanggar Beach is influenced by demographic factors and destination quality, with accessibility and facilities as the aspects that need the most improvement. Strategies to strengthen attractions, improve infrastructure, and improve amenities will support sustainable tourism growth.

Operational Standards for Water Quality Management and Vannamei Shrimp Hatchery Process at PT. Esaputlii Main Initiative of Barru Regency
type: item
description: Vannamei shrimp or Litopanaeus vannamei is a species of shrimp native to the waters of central and south America, such as Ecuador, Vanezuela, Panama, and Brazil. It was cultivated in Indonesia in 2001 to replace the species Litopanaeus monodon, which experienced decline and production failures due to poor water quality and disease risk. The purpose of this study is to find the water quality management method used to produce vannamei shrimp larvae (Litopenaeus vannamei) in PT. Esaputlii Prakarsa Utama, Barru Regency. The activity was carried out through a participatory approach and direct observation for 4 months (February to May 2025). The results of the study revealed that (1) Strict sanitation of production containers (brood rearing tanks, egg hatching, larvae, and feed cultures) with 100 ppm of chlorine was used; (2) Integrated seawater and freshwater resource management (salinity 30–33 ppt, pH 7–8.3); (3) Routine monitoring of water quality parameters (temperature: 31–34 °C, salinity: 30–32 g/L, pH: 8.1–8.5, alkalinity: 128–152 mg/L); and (4) Operational techniques such as flowthrough in the mother tank and gradual water replacement (10–30%) in the larval tank. If this can be applied to small-scale vannamei shrimp farmers in Barru Regency, it can certainly improve the quality of fry production.

The Effect Of Stocking Density On The Growth Of Sangkuriang Catfish (Clarias gariepinus) In The Bucket Fish Cultivation System (BUDIKDAMBER)
type: item
description: Sangkuriang catfish (Clarias gariepinus) is one of the most commonly cultivated freshwater fish species in Indonesia. The high production of catfish is largely due to the efforts of fish farmers who are able to produce sufficient quantities to meet the increasing consumption demand. One of the aquaculture methods used is the BUDIKDAMBER system, which involves fish farming in buckets with high stocking densities. This study employed an experimental method using a Completely Randomized Design (CRD) consisting of 3 stocking density treatments with 4 replications: A (1 fish/liter), B (2 fish/liter), and C (3 fish/liter) for a period of 30 days. The fish were kept in buckets prepared for the budikdamber activity, with stocking densities adjusted according to each treatment, and were fed three times a day. Water quality was monitored every 3 days. The results of the study showed that up to a density of 3 fish/liter of Sangkuriang catfish fingerlings, there was no significant difference among the different stocking density treatments, and all treatments still demonstrated good performance. The best treatment was found in treatment C (3 fish/liter), with a survival rate of 77.25%, a feed conversion ratio (FCR) of 0.67, and a specific growth rate (SGR) of 3.28%.

Shrimp Vannamei Culture (Litopenaeus vannamei) in Low Salinity Media on Biofloc System With Different C/N Ratio Media Intake
type: item
description: Vannamei shrimp (Litopenaeus vannamei) is one of the superior commodity biota in the fisheries sector with one of its etyhaline abilities, namely that it can survive a wide salinity range, so it has the potential to cultivate vannamei shrimp in fresh water media. One of the cultivation systems that is currently developing is the biofloc system with the advantage of increasing the production capacity of dense biota but still being able to maintain water quality through the floc produced, apart from that it can increase biota production where the floc is able to become natural food for the biota being reared. The development of freshwater vaname shrimp cultivation using a biofloc system has never been carried out, where one of the important factors of biofloc itself is the C/N ratio for floc growth, therefore it is necessary to determine the correct C/N ratio given to the freshwater vaname shrimp biofloc media. The aim of this research is to analyze the maintenance of low salinity vaname shrimp using a biofloc system at different C/N ratios. The research method used was the experimental method with a completely randomized design (CRD) consisting of 4 treatments and 3 replications, namely P1 C/N 6, P2 C/N ratio 12, P3 C/N ratio 18, and P4 C/N ratio 18. N 24. The results of this study show a real difference in the specific weight growth rate with the highest value at P3, namely 9.0%/day and the lowest at P1, namely 0%/day. The specific length growth rate in P3 shows the highest value, namely 4.18%/day and the lowest in P1, namely 0%/day. The FCR value in the study also showed the best results at P3 with a value of 1.57.

The Effect Of Candlenut (Aleurites moluccanus) Concentration On Moisture Content, Ash Content, Color, And Sensory Evaluation Of Powdered Broth From Bones And Heads Of Mackerel (Rastrelliger sp)
type: item
description: Fish-based powder broth generally has a fishy odor caused by the high content of trimethylamine (TMA) compounds in fish. To reduce this unpleasant smell, candlenut is added as an antioxidant. This study aims to determine the effect of candlenut concentration on the moisture content, ash content, color, and sensory characteristics of powder broth made from the bones and heads of mackerel. The study used a Completely Randomized Design (CRD) with further analysis using the Honestly Significant Difference (HSD) test at a 5% level. The research was conducted in two stages: product preparation and analysis, which included chemical tests (moisture and ash content), physical tests (color), and sensory evaluation. The results showed that the addition of candlenut had a significant effect on all tested parameters. Formulation K4 yielded the best results, with a moisture content of 5.80%, ash content of 3.42%, and color values of L 75.84, a 2.48, and b* 19.91. The sensory scores for this formulation were 4.36 for taste, 5.16 for aroma, 5.26 for color, and 4.54 for texture. These findings indicate that the addition of candlenut can improve the physical and sensory quality of fish-based powder broth and reduce the undesirable fishy odor

The Effect of Recombinant Growth Hormone Administration on Bonylip Barb (Osteochilus vittatus) Fry at Diferent Stocking Densities.
type: item
description: The nilem fish (Osteochilus vittatus) has high economic value, but its growth rate is relatively slow. One potential solution to accelerate its cultivation period is the use of recombinant growth hormone (rGH). This study aimed to evaluate the effect of oral administration of rGH derived from Epinephelus lanceolatus (rElGH) on the growth rate of nilem fish juveniles at different stocking densities. A completely randomized design with three replications was used in this study. Juvenile fish with an average length of 4.43±0.03 cm and weight of 0.96±0.03 g were reared in aquaria measuring 100 × 50 × 50 cm with a water height of 20 cm for 30 days. The fish were fed commercial feed containing 31–33% protein, with rElGH-supplemented feed given to satiation twice daily (at 08:00 and 16:00) during the first seven days, followed by regular feed without rElGH. The best production performance was obtained in the R30 treatment group (30 fish per 100 L with rElGH), with an absolute weight gain (AWG) of 3.4 g, a survival rate of 98.89%, and a specific growth rate (SGR) of 4.8% per day, indicating that nilem fish given rElGH grew faster.

Financial Viability Assessment of Koi (Cyprinus Rubrofuscus) Culture Through Selective Breeding Programs : A Case Study of Indonesian Commercial Koi Farms
type: item
description: This study aims to evaluate the financial performance of the koi fish farming industry (Cyprinus rubrofuscus) in Indonesia through a selective breeding program. Data collected between 2021 and 2024, covering business development, operational costs, investment costs, and capital estimates, was obtained from 24 koi fish farming businesses in the Java region. Businesses using genetic screening aim to reduce financial disparities, which is different from traditional aquaculture methods. The analysis's results indicate that the implementation of the selective breeding program in a scientific manner yielded a higher profit margin of 34.2% than the traditional method, which only reached 18.7%. Although the initial investment is more substantial (about Rp28,5 million per hectare), the time frame required to pay for the investment is more efficient, i.e., between 18 and 24 months. The price of koi fish is higher than the market price, possibly reaching 2.8% of the price of koi fish, with the selling price per tail ranging from Rp450,000 to Rp1,200,000. In addition, there was a 15% increase in feed efficiency and a 3% decrease in mortality, which means a 7.8% reduction. Thus, this selective breeding program can improve koi farming production and sales performance by applying genetic technology, which can help overcome the financial crisis in the aquaculture sector in developing countries.

Identification of Gastropod Species in the Waters of Moudolung, East Sumba Regency
type: item
description: The intertidal zone is an area that has a narrow area because it borders land and is influenced by tides. The types of biota in tidal areas have high diversity. There are many types of biota such as fish, bivalves, coral reefs, gastroda and there are also types of plants such as macroalgae, seagrass and mangroves. One of the biota found in tidal areas is Gastropods from the phylum mollusca which has quite abundant species diversity. With location conditions such as sandy, muddy and rocky substrates. Moudong waters are waters that have rocky and muddy topography, so they are a place/habitat for gastropod species. The aim of this research was to see the level of diversity of gastropod types and nutritional content. The method used is the observation and line transect method, with 9 stations and 9 plots on each transect. Based on the results of research on the types of gastropods in Moudong waters, there are 5 types of gastropods, namely Oliva fordi, Telescopium Telescopium, Steromphala umbilicalis, Canarium labiatum, Familia muricidae. The level of diversity of gastropod species is low with an H' index < 2.0, because there is only 1 type at each sampling station. For nutritional content (proximate analysis results), it was found that the nutritional content of the gastropod species obtained in Moudolung waters was quite high, one of which was that the protein content of each type was quite high.

Identification Of Freshness Level Of Mackerel (Rastrelliger Kanagurta) In Tanjungsari Market, Sumedang Regency.
type: item
description: Fresh fish or wet fish is fish that has not been or is not preserved with anything except simply cooled with ice. Fish is said to have maximum freshness if its properties are still the same as live fish, both in appearance, taste, and texture. The level of freshness of fish can be identified or assessed organoleptically. Human senses are instruments used in Volume 5, Number 2, June 2025 https://journal.unram.ac.id/index.php/jmai/index. E-ISSN : 2798-0553 31 organoleptic tests, which include sight, smell, taste, touch and hearing. This study aims to determine the level of freshness of mackerel and fresh fish at Tanjung Sari Market organoleptically. This research method is by taking mackerel samples and at 10.00 WIB, then its freshness is identified qualitatively through organoleptic observations. Sampling was carried out on May 20, 2025. Organoleptic assessment is the most widely used method in determining signs of fish freshness because it is easier and faster to do, does not require a lot of equipment, and does not require a laboratory. Subjective (organoleptic) determination of fish quality decline is carried out using a score sheet that has been set by the National Standardization Agency SNI 01-2346-2006 (BSN 2006) and using 5 (five) panelists. The parameters observed are the condition of the eyes, gills, mucus, meat, odor, and texture. For organoleptic observations, a detailed assessment (see the score sheet table) is carried out on the fish in the range of values 1 to 9. In the organoleptic testing of test fish sold in retail by traders at Tanjungsari market, the values obtained ranged from 7-8, which means that the fish still has good quality and meets the requirements set by SNI (2006), namely the standard for fresh fish for organoleptic testing, which is a minimum of 7.

Identification Of Salmonella sp. In Smoked Fish In Jayapura City
type: item
description: The purpose of this study was to assess the microbiological quality of smoked fish at the processing center in Jayapura City, Papua. 100 kilograms of smoked fish were tested, samples were taken from producers, distributors, and retailers at three distribution levels. Microbiological tests included identification of Salmonella sp. bacteria and Total Plate Count (TPS) tests. The results of the study were conducted using ANOVA and DMRT further tests at a significance level of 95%. The average TPS value at all distribution levels ranged between 3.379 and 3.509 log cfu/g, which is still within the safe limit for consumption (p>0.05). Each sample tested did not show any Salmonella sp. contamination. This study shows that smoked fish products in Jayapura City are microbiologically safe, but care during distribution needs to be improved, especially in terms of packaging and cleanliness, so that the product continues to satisfy consumers. Consumers can be more satisfied and shelf life can be extended with better hygiene, packaging, and better distribution chain management. The results of this study provide important insights for producers, consumers, and related parties about the quality of Jayapura smoked fish. This information can be used as a basis for fisheries policy and product quality improvement.

The Effect Of Giving Maggot (Chrysomya megacephala) Maintained In Different Media On The Production Performance Of Nile Fish (Orechromis niloticus)
type: item
description: Nile tilapia is a high-value aquaculture commodity. Its production increased from 24.98% in 2018 to 26.76% in 2019, showing a 7.11% rise. In tilapia farming, feed is a major factor, but its high cost has encouraged the search for alternative feeds. Maggot offers a promising solution due to its low cost and high protein content (40–50%) along with essential amino acids. This research used an experimental method with a completely randomized design (CRD), consisting of 4 treatments and 3 replications: P1 (household waste), P2 (fruit waste), P3 (tofu dregs), and P4 (chicken manure). Egg hatching was carried out in plastic containers with a moist mixture of pellet and water. After one week, larvae were transferred to wooden rearing containers filled with 2 kg of each type of waste. The maggot rearing process lasted for two weeks. Maggots were harvested at three weeks old, then dried by roasting and used as fish feed. Tilapia were reared for 45 days in 12 aerated containers and fed maggots three times a day. Water quality was monitored weekly. The results showed that weight gain, specific growth rate (SGR), absolute length, specific length growth rate (SLGR), and blood glucose levels were significantly affected by the treatments. However, feed conversion ratio (FCR) and survival rate (SR) were not significantly different. The best results were obtained from P1 (household waste), with absolute weight gain of 11.42 g, SGR of 1.67%/day, absolute length of 4.92 cm, SLGR of 1.02%/day, FCR of 1.9, survival rate of 84.44%, and blood glucose level of 73.3 mg/dL.

Comparative Analysis of Chlorella vulgaris Cell Densities in Different Culture Systems
type: item
description: Chlorella vulgaris is a cosmopolitan microalga with high nutritional value, widely utilized in aquaculture, pharmaceuticals, and biofuel production. This study evaluated its growth performance across three culture scales (laboratory bottle, carboy, and intermediate concrete tank) at BPBAP Situbondo from February to June 2024. The research aimed to analyze the influence of scale on biomass productivity and identify critical environmental factors. Results demonstrated significant growth variations among scales. The laboratory bottle (5 L) achieved the highest cell density (54 × 10⁶ cells/mL) on day 11, attributed to optimal light distribution and stable temperature (30–33°C). Carboy cultures (10 L) showed moderate productivity (31 × 10⁶ cells/mL), while the intermediate scale (700–800 L) yielded the lowest density (6.8 × 10⁶ cells/mL) due to light limitation and suboptimal aeration. Water quality parameters remained stable across all systems, with pH 8.0, salinity 30–34 ppt, and uniform light intensity (500 lux). Statistical analysis confirmed significant differences in growth rates (p < 0.05), highlighting the inverse relationship between scale size and productivity. The study concludes that small-scale systems offer superior environmental control for C. vulgaris cultivation. For mass production, design improvements—such as enhanced aeration, closed photobioreactors, and artificial lighting—are recommended to replicate laboratory-scale efficiency. These findings provide actionable insights for optimizing microalgae culture systems in aquaculture feed production.

Growth and Maintenance of Barramundi (Lates calcarifer) Fed with Commercial Feed at BPBAP Situbondo
type: item
description: This study evaluated the growth performance and maintenance of white seabass (Lates calcarifer) fed with commercial feed at BPBAP Situbondo. As a high-value aquaculture commodity with increasing market demand, white seabass farming faces challenges in seed production and growth optimization. The research monitored growth parameters, survival rate (SR), and water quality during a 4-month rearing period (February-June 2024) in concrete tanks (2.5×4×1.2 m). Results showed that commercial feeds (Megami/Skretting) administered via ad-satiation method (3-4x/day for juveniles <7cm, 2x/day for 8-14cm fish) supported growth, though size variation triggered cannibalism. Water quality parameters remained optimal (pH 7.49-8.17; salinity 33-34‰; ammonia 0.011-0.026 mg/L) per SNI 8036:2014 standards, contributing to an 83.98% SR. Key findings emphasize the critical role of routine grading to prevent cannibalism, strict feed management to minimize toxic waste accumulation (TAN peaked at 1.397 mg/L), and daily water exchange (100% replacement). The study concludes that integrated feed-water management significantly enhances white seabass productivity, recommending further research on nutrient-specific feed formulations and advanced filtration systems to address the 16% mortality rate.
