Abstract

Mangrove forests in Subang Regency have experienced changes in area coverage due to the expansion of aquaculture ponds and coastal abrasion. This study aims to analyze the changes in mangrove area and density in Blanakan Bay, Subang Regency, during the period 2018–2022 using Landsat 8 satellite imagery. The method employed is a survey approach utilizing multispectral classification. The main assumption of this study is that changes in mangrove coverage can be observed through multitemporal satellite imagery that has undergone geometric and radiometric correction. The digitized Landsat images were overlaid to identify spatial changes in mangrove cover 2018-2022. Spatial analysis was conducted using Supervised Classification techniques and the Normalized Difference Vegetation Index (NDVI) to classify mangrove areas based on their density levels. The results showed that the mangrove area in 2018 was 553.2 hectares, which decreased to 384.2 hectares in 2022, indicating a reduction of 169 hectares.

Abstract

Bontang City, located in East Kalimantan Province, has a larger marine area than land area, offering significant potential in marine fisheries resources. One of the abundant yet undervalued marine commodities is bawis fish (Gerres sp.), which remains economically underutilized. This low economic value presents a challenge, particularly for coastal communities that depend on the fisheries sector for their livelihoods. Increasing the added value of bawis fish through processing into higher-value products is therefore essential. One such initiative is the production of bawis fish chips, developed by the Processing and Marketing Group (Poklahsar) Saputra Snack, led by a local entrepreneur in Bontang. This study aims to assess the economic value added from bawis fish chips using the Hayami value-added analysis method. The findings indicate that the product yields an added value of IDR 27,151 per kilogram, with a value-added ratio of 37%. This implies that for each kilogram of raw bawis fish processed, an additional economic value of IDR 27,151 is generated. Based on the Hayami criteria, this level of value addition is classified as moderate (15%–40%). The results suggest that processing bawis fish into chips has the potential to serve as an effective strategy for enhancing the economic well-being of small-scale fishery enterprises.

Abstract

The growth of Nirwana tilapia (Oreochromis niloticus) is strongly influenced by feed and environmental conditions in aquaculture systems. In Indonesia, tilapia productivity is often constrained by feed efficiency and fluctuating water quality. Natural feed such as bloodworms (Chironomus sp.) contains high protein levels that support length growth, while pellets provide complete nutrients for weight gain. This study aimed to evaluate the effects of bloodworms, pellets, and their combination on the growth performance of Nirwana tilapia fingerlings, as well as on water quality (temperature, pH, dissolved oxygen, and ammonia). A Completely Randomized Design (CRD) was applied with three treatments: A (15% bloodworms), B (5% pellets), and C (a combination of 7.5% bloodworms + 2.5% pellets), each with four replications. The fingerlings measured 3–4 cm and were approximately two months old, reared over a period of 50 days. The results showed that all treatments led to increases in weight and length; however, based on analysis of variance (ANOVA), there were no significant differences (p > 0.05) in all growth parameters: weight gain (2.20–2.22 g), length gain (1.32–1.48 cm), specific growth rate (2.41–2.66%/day), daily weight gain (2.73–2.85%/day), and daily length growth (0.0196–0.0210 cm/day). Descriptively, treatment B yielded the highest weight, while treatment A had the highest daily length growth. Water quality remained within optimal ranges (25.5°C temperature, pH 8.2–8.3, DO 4.5–4.7 mg/L, ammonia 0.00–0.01 mg/L). Bloodworms were more effective in stimulating length growth, whereas the feed combination was more efficient in increasing body weight. This study contributes to the development of alternative feed formulations and provides practical recommendations to enhance aquaculture productivity efficiently, sustainably, and in an environmentally friendly manner.

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.
