Abstract

This study aims to analyze the Importance Value Index (INP) of mangrove vegetation in the Purwawinangun Village area, Suranenggala Subdistrict, Cirebon Regency. The research was conducted over a period of three months, from June to August 2023, with the study area divided into three observation sites based on specific geographic coordinates. A survey approach was employed using purposive sampling. Vegetation data were collected using the transect line plot method and subsequently analyzed to determine the INP for each mangrove species. The results revealed that the mangrove species with the highest density, in descending order, were Avicennia marina (7,666.67 trees/ha), Acanthus ilicifolius (2,300 trees/ha), Rhizophora mucronata (900 trees/ha), Pluchea indica (666.67 trees/ha), Sonneratia caseolaris (300 trees/ha), and both Leucaena leucocephala and Jatropha curcas L. (66.67 trees/ha each). Rhizophora mucronata recorded the highest frequency (37.5%), highest relative canopy cover (53.10%), and a canopy closure value of 0.96. This species also exhibited the highest INP at 95.58%, while Leucaena leucocephala had the lowest at 8.32%. These findings indicate that Rhizophora mucronata ecologically dominates the mangrove community in the study area. Its dominance is attributed to its strong adaptability to varying salinity levels, water depth, and muddy soil characteristics. This species plays a crucial role in sustaining mangrove ecosystem resilience and provides significant ecological benefits for coastal protection against erosion and climate-related changes.

Abstract

Indonesia has great potential in seaweed exports, but its utilization was still not optimal due to various barriers in the trade system. This study aimed to analyze the development of Indonesian seaweed exports to seven main destination countries during 2013–2023, assess the condition of the trade facilitation index, and examine the influence of these variables on exports. The method used was a quantitative approach with a gravity model and panel data. The research results showed that the GDP of destination countries and the quality of trade and transport infrastructure had a positive and significant effect on Indonesia's seaweed exports. Conversely, Indonesia's GDP, logistics competence, and customs efficiency did not have a significant effect. The corruption perception index showed a significant negative effect on exports. These findings confirmed that external factors such as the purchasing power of destination countries and the quality of infrastructure had a major influence, while internal factors such as corruption were a major obstacle. Therefore, export enhancement strategies should be focused on trade governance reforms, strengthening export infrastructure, and developing markets in countries with high trade facilitation indices.

Abstract

Plastic pollution has become pervasive in aquatic environments, emerging as a significant ecological concern over the past decade. Plastic debris varies in size, from large fragments to microplastics—particles less than 5 mm in diameter—that result from the primary (manufacturing production) and secondary (degradation from larger plastics) sources. In aquaculture systems, these microplastics can accumulate in both the environment and within aquatic organisms, as their decomposition is a prolonged process. The persistence of microplastics poses risks to biota, including potential physical harm and chemical exposure. This review discusses current research on the presence and impact of microplastics in aquaculture, highlighting the negative effects observed. The findings indicate that microplastics represent an escalating threat to aquaculture systems, necessitating periodic monitoring and the standardisation of analytical methods to manage and mitigate their impact effectively.​

Abstract

This study aims to analyze the vibration levels of the refrigeration compressor on the fishing vessel Binama 07 Jakarta to evaluate operational conditions and detect potential component failures. Measurements were conducted using a vibration meter in three directions horizontal, vertical, and axial and a digital tachometer to determine the engine’s rotational speed in RPM. The assessment refers to ISO 20816-3:2022, a standard used to classify the condition of rotating industrial machinery. Vibration data collected from November 3–23, 2024, showed that most values fell within Zone B (acceptable), while some reached Zone C (not recommended for long-term operation). Only two days, November 12 and 23, recorded values in Zone A (good), with a vibration level of 1.6 mm/s. No data fell into Zone D (dangerous), indicating no signs of extreme vibration. However, consistent readings in Zone B and occasional spikes into Zone C suggest early signs of machine condition degradation. These findings have significant implications for the performance of the ship’s cooling system, as excessive vibration can affect the stability of the storage temperature for the catch. In the fishing industry, unstable temperatures can directly impact product quality and market value. Therefore, regular vibration monitoring is recommended as a predictive maintenance strategy to maintain optimal performance of the refrigeration system on fishing vessels.

Abstract

The freshwater lobster Cherax quadricarinatus is an aquaculture commodity with high economic value, yet it remains relatively unfamiliar to the general public. Nevertheless, market demand for this species has shown a significant upward trend, both domestically and internationally. In Indonesia, the increase of aquaculture production specially on freshwater lobster has not been sufficient to meet existing demand, primarily due to the limited availability of high-quality broodstock and the low reproductive capacity of female brood lobsters. One potential strategy to address this issue is the optimization of feed quality. This study aims to evaluate the effects of a dietary combination consisting of mung bean sprouts (Vigna radiata), white sweet potatoes (Ipomoea batatas), and commercial pellets enriched with vitamin E on the reproductive performance of female freshwater lobsters. The results indicated that the best feed formulation was observed in Treatment P3, which consisted of 25% mung bean sprouts, 50% Fengli 3 pellets + vitamin E, and 25% white sweet potatoes. This treatment accelerated gonadal maturation to 25 days and resulted in a fecundity of 467.33 eggs, a fertilization rate (FR) of 97.84%, a hatching rate (HR) of 92.70%, and a survival rate (SR) of 90.87%. The content of vitamins A, C, and E in mung bean sprouts is known to stimulate spawning and enhance embryo hatchability, while bioactive compounds in white sweet potatoes contribute to the synthesis of reproductive hormones such as estrogen and vitellogenin.

Abstract

Caulerpa racemosa is a type of green macroalgae with high economic value that has the potential to be cultivated intensively. This study aimed to evaluate the effect of planting depth on the vegetative growth of Caulerpa racemosa cultivated in a tarpaulin tank system. Three planting depths were tested: 20 cm, 40 cm, and 60 cm. Vegetative growth parameters observed included Absolute Growth in Weight, Absolute Growth in Stolon Length, and Absolute Growth in Ramuli Length over a defined cultivation period. The results indicated that the 60 cm planting depth yielded the highest vegetative growth, with mean weight reaching 137.67±3.21 g, stolon length 30.04±0.54 cm, and ramuli length 25.29±2.90 cm. Statistical analysis revealed a significant difference only in stolon length between the 60 cm and 40 cm treatments, while differences in weight and ramuli length were not statistically significant. Overall, the data suggest that a 60 cm planting depth provides a more stable microenvironment in terms of light intensity, water temperature, and protection from physical disturbances, thereby enhancing biomass accumulation and vegetative structure development in Caulerpa racemosa. Therefore, a planting depth of 60 cm is recommended as the optimal depth for cultivating Caulerpa racemosa in tarpaulin-based culture systems.

Abstract

Banggai Cardinalfish (BCF) habitat is found in protected waters, such as Lalong Bay, Banggai Regency. Banggai cardinalfish are associated with various biota such as sea urchins (especially Diadema setosum) which live close to coral reef, seagrass and mangrove ecosystems. The aim of this research was to analyze marine debris contamination in Banggai cardinalfish habitat in Lalong Bay. This research used a quadrat sampling method (2m x 2m) along 20 m-30 m line transects at 4 research stations. Based on the analysis, organic marine debris types comprised: medium-sized pieces of wood, wood chips, coconuts, coconut husks, leaves and fish carcasses. Inorganic marine debris types comprised glass bottles, tin cans, light bulbs, baby diapers, cooking oil bottles, mineral water bottles, plastic cups, plastic spoons, toothbrushes, buoys, plastic packaging, plastic baskets, lighters, ropes, fishing nets, styrofoam, rubber sandals, tires and other plastic debris. The average amount of debris was 17 items/m2, volume 0.13 m3, weight 1,251 gr/m2 at Station 1; 16.75 items/m2, volume 0.10 m3, weight 1,157 gr/m2; at Station 2; 20.5 items/m2, volume 0.04 m3, weight 2,341 gr/m2 at Station 3 26.3 items/m2, volume 0.07 m3, weight 1,895 gr/m2 at Station 4. Based on observations at these stations in the port, much of the BCF fish habitat was found to be exposed to marine debris due to high levels of human activity and a lack of waste management capacity.

Abstract

Amahai and Sehati are located in Central Maluku Regency, Maluku Province, which has a diversity of seagrass species spread across the intertidal and subtidal zones. The purpose of this study was to determine (1) the distribution of seagrass in the intertidal and subtidal zones, (2) the diversity value of seagrass species in the intertidal and subtidal zones. The study was conducted from 8 to 21 December 2024 using the linear quadrat transect method. 3 transects were made in Amahai waters and 5 transects in Sehati waters. Each transect consisted of 10 quadrats measuring 1x1 meter. The study found 3 types of seagrass, namely Cymodocea serrulata, Halodule pinifolia, and Halophila ovalis in the intertidal zone and Enhalus acoroides and Thalassia hemprichii seagrass species were found in the subtidal zone. The Physico-Chemical Factors of Amahai waters in the intertidal zone found seawater temperature of 280C, salinity of 27.40/00, and pH of 7.4. The Physico-Chemical factors of Amahai waters in the subtidal zone are, temperature 280C, salinity 29.10/00, and pH 7.3. The average physico-chemical factors in the tidal zone in Sehati coastal waters are, sea air temperature of 290C, salinity of 26.50/00, and sea air pH of 7.5. The average physico-chemical factors in the subtidal zone of Amahai waters are, temperature 290C, salinity 28.40/00, and pH 7.5. The distribution pattern of seagrass in the intertidal and subtidal zones in Amahai and Sehati waters is relatively even. The value of the seagrass species diversity index in the tidal zone of Amahai (1.487) and Sehati waters (1.359) is classified as moderate. The value of the seagrass species diversity index in the subtidal zone of Amahai (0.675) and Sehati (0.693) is classified as moderate. This research contributes to the coastal ecosystem to improve the welfare of the community around Amahai Village and Sehati Village.

Abstract

Aquaculture technology to increase productivity includes sex reversal or masculinization. Masculinization of snakehead fish (Channa striata) is essential to balance the male sex ratio for sustainable aquaculture. One approach is the use of natural compounds to reduce dependence on synthetic hormones that are less environmentally friendly. Natural substances such as mangosteen peel extract (Garcinia mangostana) contain aromatase inhibitors. This study aimed to determine the optimal dosage of mangosteen peel extract for inducing sex reversal in snakehead fish. Two-week-old fry were immersed in different treatments (control 0 g/L, 0.5 g/L, 0.7 g/L, and 0.9 g/L) for 4 hours and reared for 2 months. Gonads were examined microscopically using aceto-carmine staining. Results showed that the highest male proportion was obtained at 0.9 g/L, while the highest survival rate was recorded at 0.7 g/L. The Kruskal–Wallis test (H=7.64; p=0.054) indicated no significant differences among treatments in male proportion. The Mann–Whitney U test (p=0.077) between control and each treatment confirmed that formal differences were not significant, although a trend of increased male proportion was observed across all treatments. One-way ANOVA (F=16.72; p=0.0008) demonstrated that treatment doses significantly affected survival. Tukey HSD revealed that all treatments differed significantly from control (p<0.05), while no significant differences occurred among treatment doses (p>0.05). In conclusion, doses of 0.5–0.9 g/L were effective in promoting masculinization while maintaining optimal survival in snakehead fish.

Abstract

The Klawing River plays an essential role as a source of livelihood for local communities and as a habitat for various fish species, yet it is increasingly under pressure from human activities and environmental changes. This study aims to identify the forms of local wisdom practiced by fishing communities in managing fishery resources and to assess their relevance to modern challenges. The research was conducted in five villages representing the upstream, middle, and downstream sections of the river using a qualitative descriptive approach through interviews and observations involving 40 respondents. The results show that local wisdom is reflected in the use of traditional fishing gear (nets, gillnets, fishing lines, paser, wuwu, and mijahan), the application of the pranata mangsa as a seasonal fishing guide, social solidarity among fishers, and the Gredug Sampah tradition focused on maintaining river cleanliness. These practices now face limitations due to climate change, the introduction of invasive species, and economic pressures. The declining accuracy of the pranata mangsa indicates the need to integrate traditional ecological knowledge with modern climatological information to enhance community adaptation to ecosystem dynamics. Therefore, the synergy between local wisdom and scientific approaches is crucial for achieving an adaptive and sustainable fishery resource management system in the Klawing River.
