Abstract

Whiteleg shrimp (Litopenaeus vannamei) is a leading aquaculture commodity with high economic value and can be farmed intensively with high stocking density. Intensive farming systems have the potential to increase the accumulation of organic matter and metabolic waste, which can trigger the growth of pathogenic bacteria such as Vibrio sp. The presence of these bacteria can cause health disturbances in shrimp and reduce survival rates. The purpose of this study is to determine and test the effectiveness of probiotics in suppressing the population of Vibrio sp. in whiteleg shrimp (Litopenaeus vannamei) farming. Data collection methods were carried out primarily and secondarily through direct observation, interviews, active participation in the field, documentation, and literature studies. Control techniques were performed through several stages, namely pond preparation, probiotic culture using molasses and skim milk, mixing probiotics into feed, application of probiotics to ponds. as well as routine monitoring of water quality. The observed parameters include nitrate (NO₃), nitrite (NO₂), ammonium (NH₄), phosphate (PO₄), alkalinity, Total Organic Matter (TOM), and the total population of Vibrio sp. The results of the study showed that the application of commercial probiotics was effective in suppressing the growth of Vibrio sp. with a population density of 103-104 CFU/ml during cultivation through the mechanisms of nutrient competition and the production of antibacterial compounds, as well as helping to maintain the stability of pond water quality within the optimal range for shrimp growth.

Abstract

A common problem faced by betta fish breeders during the hatchery stage is the low survival rate of fry, as they are highly susceptible to changes in water quality and disease. Therefore, fry management is necessary to increase survival rates by using natural ingredients that are environmentally friendly and do not cause resistance. Ketapang leaves (Terminalia catappa) and betel leaves (Piper betle) can be used because they contain active compounds such as flavonoids, which have antimicrobial properties that can help inhibit the growth of bacteria and fungi in the water. The aim of this study was to determine the appropriate dosage of ketapang leaves and betel leaves for the survival rate of betta fry. This study used an experimental method, namely RAL with 4 treatments and 3 replications, the treatments tested were P0 (control): no treatment, P1: 1 g/l ketapang leaves, P2: 1 g/l betel leaves, P3: 0.5 g/l ketapang leaves and 0.5 g/l betel leaves. The parameters tested included absolute weight, absolute length, specific weight growth, daily length growth and survival rate. The results showed that the average absolute weight of betta fish ranged from 0.193-0.444 g, the average absolute length ranged from 2.379-3.021 cm, the average specific growth rate ranged from 0.015-0.006%/day, the average daily growth rate ranged from 0.034-0.019%/day, and the average survival rate ranged from 60.00-13.33%.

Abstract

Mozambique tilapia (Oreochromis mossambicus) is an important aquaculture commodity in Indonesia; however, its productivity can be constrained by disease outbreaks, including Aeromonas hydrophila infection. The use of natural feed additives containing nutritional and bioactive compounds is a promising strategy to improve fish growth and health. This study aimed to evaluate the effectiveness of octopus (Octopus sp.) ink extract supplemented in feed on the growth performance of Mozambique tilapia infected with A. hydrophila. The study was conducted for 45 days using a completely randomized design with five treatments and three replications. The treatments consisted of a positive control, namely feed without octopus ink extract with A. hydrophila infection (K+); a negative control, namely feed without octopus ink extract and without A. hydrophila infection (K-); and feed supplemented with octopus ink extract at 50, 100, and 150 ml/kg feed followed by A. hydrophila infection (A, B, and C, respectively). The observed growth parameters were absolute weight gain, absolute length gain, specific weight growth rate, and specific length growth rate. The results showed that octopus ink extract supplementation improved all growth parameters compared with the positive control. The best performance was obtained in treatment B (100 ml/kg feed), with an absolute weight gain of 10.77±1.53 g, absolute length gain of 2.65±0.39 cm, specific weight growth rate of 2.59±0.11%/day, and specific length growth rate of 2.16±0.05%/day. Therefore, octopus ink extract has potential as a natural feed additive to enhance the growth performance of Mozambique tilapia challenged with A. hydrphila.

Abstract

Lewoleba is one of the villages in Nubatukan Sub-district, Lembata Regency, East Nusa Tenggara, which has a coastal area and a mangrove ecosystem with a muddy substrate that is suitable as a habitat for Telescopium telescopium. This study aimed to evaluate the effect of different macroalgae diets on the growth and survival rate of mangrove snails, T. telescopium, cultivated in the coastal area of Lewoleba. The experiment was conducted for three months using a completely randomized design (CRD) consisting of four treatments with three replicates each: A (Ulva lactuca), B (Padina sp.), C (Gracilaria corticata), and D (a combination of the three macroalgae species). Parameters observed included absolute weight growth, absolute length growth, survival rate, and water quality. The results showed that the treatments significantly affected absolute weight gain, with the highest growth recorded in treatment D (1.34 g) and the lowest in treatment A (0.59 g). The highest absolute length growth was also observed in treatment D (0.84 cm), although it was not significantly different from the other treatments. Survival rates ranged from 76.67% to 83.33% and did not differ significantly among treatments. Water quality parameters throughout the study remained within suitable ranges for mangrove snail cultivation. In conclusion, feeding with combination of macroalgae (Ulva lactuca + Padina sp. + Gracilaria corticata) produced the best results in promoting the growth of mangrove snails (T. telescopium) compared to feeding a single type of feed.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) are the backbone of the Indonesian economy and the culinary MSME sector in Bengkulu City is growing rapidly, supported by abundant marine resources and increasing consumer demand. In this context, the fish-based culinary business Evi Tenggiri has begun adopting cashless payment systems such as e-wallets, mobile banking, QRIS, and debit/credit cards, yet cash transactions still dominate daily operations. This study aims to analyze the level of cashless payment usage and to identify the factors that influence consumers in using cashless payments at Evi Tenggiri MSMEs in Bengkulu City. An accidental sampling technique was applied to consumers who conducted cashless transactions within the last month. Descriptive analysis was used to describe respondent characteristics and the intensity of cashless payment usage, while binary logistic regression was employed to examine the determinants of usage. The results indicate that most consumers are in the “frequently use” category, although cashless payments have not fully replaced cash in routine transactions. Furthermore, ease of use and service quality have a significant positive effect on the likelihood of using cashless payments, whereas security and compatibility do not show a significant influence. These findings suggest that consumer decisions are primarily driven by practical benefits directly perceived during transactions rather than by security concerns or lifestyle considerations. The study concludes that strengthening cashless payment adoption in MSMEs requires improving ease of use and service quality while maintaining adequate security standards.

Abstract

Probiotics and prebiotics are promising functional feed additives in aquaculture because they can improve gut health, nutrient utilization, growth, and survival of cultured aquatic species. This study aimed to evaluate the effects of different probiotic dosages in a tomato meal enriched diet on growth performance, feed utilization efficiency, and survival of whiteleg shrimp. The experiment was conducted using a completely randomized design consisting of four treatment and three replicates. The treatments included PR-5, PR-10, and PR-15, representing tomato meal-enriched diet supplemented with 5, 10, and 15 mL probiotic/kg feed, respectively, and WPR, representing tomato meal-enriched diet without probiotic supplementation. The shrimp were reared for 30 days and evaluated for weight gain, specific growth rate, feed conversion ratio, feed efficiency, and survival rate. The results showed that probiotic supplementation significantly affected weight gain, feed conversion ratio, feed efficiency, and survival rate (P < 0.05), but did not significantly affect specific growth rate on day 15 or day 30 (P > 0.05). The PR-15 treatment produced the highest weight gain of 7.53 g, the lowest feed conversion ratio of 15.68, the highest feed efficiency of 6.39%, and the highest survival rate of 80.00%. These findings indicate that supplementation with 15 mL probiotic/kg feed in a tomato-meal enriched diet was the most effective treatment for improving growth performance, feed utilization efficiency, and survival of whiteleg shrimp. Therefore, this dietary strategy may support more efficient and sustainable whiteleg shrimp culture.

Abstract

Sinularia sp. is one of the most widespread and abundant types of soft coral in Indonesian waters. The soft coral Sinularia sp. haves many bioactive compounds to use as a patogen antibacterial agent. The aim of this research was to compare the antibacterial activity from the soft coral Sinularia sp. against the pathogenic bacterial strain Escherichia coli. Samples of the soft coral Sinularia sp. were collected by SCUBA diving equipment at around Pahawang Island, Pesawaran Regency, Lampung, Indonesia, in July 2025. In this study, two species of soft corals, Sinularia polydactyla and Sinularia flexibilis, were found at the research site. The extract yields for soft coral species used methanol resulted in higher values compared to ethyl acetate and hexane. The antibacterial activity of the extract soft corals against the pathogenic bacteria E. coli used ethyl acetate solvent better than methanol and hexane. Soft coral extract for Sinularia sp. with ethyl acetate solvent can be used as antibacterial candidates against the pathogenic bacteria E. coli.

Abstract

Shrimp aquaculture is a critical part of the global seafood industry but remains highly vulnerable to environmental fluctuations and disease outbreaks, largely due to inadequate water quality management. Recent advances in deep learning and real-time streaming data offer promising solutions for intelligent monitoring and control. This systematic literature review evaluates state-of-the-art approaches integrating deep learning models and streaming architectures for water quality monitoring in shrimp aquaculture. Following PRISMA guidelines, 38 peer-reviewed studies published between 2020 and 2025 were selected from Scopus, with emphasis on tropical aquaculture systems. The findings are organized into four themes: predictive deep learning models, smart sensing technologies and data sources, streaming and edge computing architectures, and behavioral monitoring with production outcomes. LSTM, GRU, and CNN models show strong performance in predicting dissolved oxygen, pH, and temperature. Data are commonly collected through IoT sensors, UAVs, and AI-based imaging systems, enabling high-speed acquisition and detailed spatial information. Streaming platforms such as Apache Kafka, combined with embedded AI and edge computing, support near-real-time analytics and responsive system operation. Visual behavioral monitoring further enables early detection of stress indicators and improves operational efficiency. Overall, integrating deep learning with streaming data can substantially enhance sustainability and efficiency in shrimp farming. However, challenges remain in standardization, scalability, and behavioral modeling. Future research should prioritize benchmarking, hybrid edge–cloud architectures, and long-term validation studies.

Abstract

Global warming poses a critical challenge worldwide, driven by high levels of carbon emissions. This study aims to evaluate the carbon sequestration potential of Kappaphycus alvarezii seaweed cultivated using the longline system in Bondo waters, Mlonggo District, Jepara Regency. The research involves measuring carbon absorption, analyzing carbon content, estimating the total carbon sequestration potential of the cultivation area, and assessing the relationship between water quality parameters and carbon absorption levels. Samples were collected periodically on days 14, 28, 42, and 49 during a single cultivation cycle. Results reveal a total carbon absorption of 305.21 tons of C per cycle (1,831.27 tons of C per year) with the highest carbon content recorded at 43.68% on day 28. The total carbon sequestration potential across an effective cultivation area of 44.36 hectares is estimated at 40,617.79 tons of C annually. The study also identifies a positive correlation between carbon absorption, biomass growth, and water quality parameters such as brightness, salinity, and pH. These findings support the development of seaweed cultivation as a viable solution for mitigating carbon emissions through integration into carbon trading schemes and blue economy programs. This research makes a significant contribution toward Indonesia's net zero emissions target by 2060 while offering sustainable economic and social benefits for coastal communities. Further studies are recommended to explore the long-term effects of repeated cultivation cycles and the diversification of other seaweed species.

Abstract

Blood cockles are widely distributed in the coastal waters of West Lombok and are commonly consumed due to their high nutritional value. However, as filter-feeding organisms, cockles have the ability to bioaccumulate heavy metals, making them effective bioindicators of aquatic pollution. This study aimed to analyze the concentration of Cadmium (Cd) in blood cockles (Anadara granosa) and sediments collected from the coastal waters of Pantai Cemara, West Lombok. Sampling was conducted from January to September 2025 at three observation stations determined based on fishermen’s information regarding potential pollution sources. The results showed that Cd concentrations in cockles ranged from 0.039 to 0.047 mg/kg, with an average value of 0.044 mg/kg. Cd concentrations in sediments ranged from 0.013 to 0,019 mg/kg, also well below the sediment quality guideline value of 25 mg/kg.
