Abstract

Abstract During Covid-19 outbreak, the production of the Vannamei Shrimp (Litopenaeus vannamei) actually increased and even increased the value of Indonesia's exports. The existence of shrimp culture is closely related to the nature of the surrounding environment, especially climate change. Climate change has a potential impact on aquaculture production, which affects livelihoods that depend on aquaculture. This study aims to analyze the development of sea surface temperature (SST) and high tides over the last 10 years and to analyze the vulnerability of the vannamei shrimp culture to climate change. This research uses a descriptive method. Data were collected through direct interviews with respondents, while the model was a structured interview. Secondary data were obtained from satellite imagery through geographic information systems, and from literature. Data analysis used spatial analysis with Geographic Information Systems (GIS), and vulnerability analysis was carried out to build the Livelihood Vulnerability Index matrix. The results show that climate change affects the development of sea surface temperature (SST) and high tides on the coast of Banyuwangi Regency, East Java Province, Indonesia. It is proven that during the last 10 years SST and high tide data shows that it fluctuates every year, SST between 27.75-29.6°C, the high tide between 1.47-1.57 m. Changes in SST affects high tide, and both become variability that affects vannamei shrimp culture. The results of the vulnerability analysis show that vannamei shrimp culture livelihoods in Banyuwangi Regency are categorized as vulnerable to climate change, with a value of 3.30 (3.34 vulnerability threshold). Highlight Research 1. Climate change affecting livelihood vulnerability of vannamei shrimp culture

Abstract

Abstract Hydrocarbon contamination is one of the most significant environmental problems, including in the marine environment. Several methods, such as chemical and physical remediation, have been constructed to remediate pollutants but remain side effects and have a relatively high cost. Bioremediation is an alternative method for degrading contaminants due to its eco-friendliness and low cost. During bioremediation, the enzyme oxygenase is produced by bacteria to degrade pollutants. However, the oxygenation enzyme's activity and compound profile during this bioremediation process are still sparsely explored. This study aimed to analyze oxygenation enzyme activity and compound profiles during the hydrocarbon bioremediation process by bacterial consortia of Pseudomonas aeruginosa and Rhodococcus erythopolis. The materials of this research were the oxygenase enzyme activity, compound profile, and amount of BOD and COD during the bioremediation process. The results showed that the monooxygenase enzyme has activity between 0.257 and 3.859 U/mL. Meanwhile, the dioxygenase enzyme has activity between 0.579 and 5.402 U/mL. The final incubation compound profile found that Hexadecanoic acid methyl ester (C17H34O2) decreased by up to 47.66%. Moreover, BOD and COD reductions were 68.59% and 67.51%, respectively. This study concluded that oxygenation enzymes were produced to degrade pollutant compounds during the hydrocarbon bioremediation process. Further research is needed to improve the effectiveness of bioremediation by enhancing enzyme activity. Highlight Research The potential of hydrocarbon-degrading bacteria (Rhodococcus erythropolis and Pseudomonas aeruginosa) for pollutant degradation in the marine environment. Enzyme activity of hydrocarbon-degrading bacteria and degradation profile of pollutants. The dynamics of BOD and COD during the bioremediation process.

Abstract

Abstract The supply of coconut crabs (Birgus latro Linnaeus, 1767) has been sourced from capture in the wild. Development efforts in aquaculture have succeeded in producing eggs. However, further development with larval maintenance failed because it was constrained by a low survival rate. This study aimed to identify the potential probiotic bacteria in coconut crabs. Coconut crab samples were collected from Moor Island, South Patani District, Central Halmahera Regency, North Maluku Province, Indonesia. The intestines of coconut crabs were taken as much as 1 g, then ground on a porcelain dish and added to Tri-Salt. The scouring liquid was taken in 0.1 ml and spread on a petri dish containing Nutrient Agar. The isolated used were marked with BL1, BL2, BL3, BL4, and BL5. Molecular identification was performed with sequencing and then analyzed using the Basic Local Alignment Search Tool (BLAST). The selection of isolates from the gastrointestinal tract of coconut crabs showed that the bacteria obtained were Enterobacter tabaci (BL1), Enterobacter hormaechei (BL2), Bacillus horneckiae (BL3), Pseudomonas stutzeri (BL4), and Acinetobacter variabilis (BL5). Further testing revealed that the bacteria A. variabilis (BL5) is a probiotic isolate in coconut crabs. Highlight Research The intestinal bacteria from coconut crabs identified were E. tabaci, E. hormaechei, B. horneckiae, P. stutzeri, and A. variabilis. The E. tabaci strain BL1, E. hormaechei strain BL2, B. Horneckiae strain BL3, and P. stutzeri strain BL4 are pathogenic bacteria. The A. variabilis strain BL5 is potential probiotics bacteria. The A. variabilis strain BL5 showed a better survival rate than other isolates.

Abstract

Abstract Fish skin is rich in collagen (80%-90%). However, catfish (Pangasius sp.) skin has a high lipid content, which can reduce the quality of collagen. Therefore, treatment is needed to remove the lipid using ultrasonic assisted extraction (UAE) with ethanol. Hence, the aim of the present study was to remove lipid content from catfish skin as a raw material for collagen by using UAE with different concentrations of ethanol (25, 50, and 75%). The research was conducted in three stages: removing impurities, collagen extraction, and characterization of collagen. The result exhibited that UAE-ethanol treatment was capable of removing up to 85.6% of lipid content, and the produced collagen had the potential to be utilized as an alternative source of collagen based on its properties. Highlight Research Ethanol could be used as extractor of lipid from catfish skin of Pangasius Ultrasonic assisted extraction could increase efficiency of lipid extraction from catfish skin. Fish skin of Pangasius sp. has a potential source for collagen. Collagen from skin of Pangasius sp. has a good characteristic with high protein content.

Abstract

Abstract Euglena sp. is a unicellular, flagellated microalga considered one of the most promising microalgal feedstock species for biofuels. Reducing  the  level  of  liquid waste pollutants  can be  done  biologically  by  using  microalgal  organisms. Its metabolites, including lipids, proteins, carbohydrates, and pigments, are appropriate for producing biorefinery products such as biodiesel and jet fuels. They can be isolated from extreme environments, such as highly acidic and ammonia-rich environments, that are not conducive to their proliferation. This study sought to determine the effect of the photoperiod or (light: dark) cycle (24 L:0 D, 12 L:12 D, 14 L:10 D, and 16 L:8 D) on the growth, biomass, metabolite content consisting of lipids, carbohydrates, and proteins, and the rate of CO­2 uptake by Euglena sp. As stated previously, the study was conducted by cultivating Euglena sp. on a laboratory scale with four photoperiod regimens. The results indicated that optimal growth, biomass content, and metabolite content were obtained with a 24 D:0 L lighting cycle. The control treatment (24 L: 0 D) had the highest biomass productivity (0.032 g.L-1.day-1 ± 0.004), lipid content (0.387 g.L-1 ± 0.031), protein content (0.542 mg.Ml-1 ± 0.007), carbohydrate content (0.409 x104 g.L-1), chlorophyll a (6.237 g.L-1 ± 0.184), chlorophyll b (2.838 g.L-1 ± 0.253), and total carotenoid (1.566 g.L-1 ± 0.105). Full light illumination (24 L:0 D) was significantly producing carotenoid content, including phaeophytin a, phaeophytin b, violaxanthin, 9'-cis-neoxanthin, dino xanthin, and fucoxanthin. Highlight Research The growth rate was higher when Euglena was cultivated under continuous illumination. The biomass productivity of Euglena increased significantly under continuous illumination. The metabolite content of Euglena (lipids, proteins, and pigments) was higher in continuous illumination.

Abstract

Abstract Iodine is proven to be an effective disinfectant for fish eggs and is commonly used in a hatchery to improve hatching and survival rates. However, tolerance to iodine can vary in different fish species, and it is essential to determine the optimal concentration to ensure successful hatchery production. This study investigated the optimum concentration and exposure time to iodine during incubation to improve rabbitfish larvae's hatching and fertilization rate from 4/2022 – 8/2022 in Thua Thien Hue, Vietnam. The study consisted of two experiments: Experiment 1 focused on different iodine concentrations: 0 ppm (C1), 50 ppm (C2), 100 ppm (C3), and 150 ppm (C4). Experiment 2 explored three exposure times: 10 minutes (T1), 20 minutes (T2), and 30 minutes (T3) to increase the fertilization, hatching, and survival rates at five days post-hatching. Data were compiled, analyzed, and compared by ANOVA using SPSS ver. 22.0. The results showed that 100 ppm iodine concentration at 20 minutes of exposure resulted in the optimum hatching, fertilization, and survival rates of S. guttatus during artificial reproduction. In the future, integrated solutions in the use of iodine solution for egg treatment and natural food supplementation at the larval stage should be recommended to improve the efficiency in artificial hatchery production of Rabbitfish. Highlight Research The concentration and incubation time of rabbitfish (Siganus guttatus) eggs affect the production efficiency of fingerling fish. Iodine concentration of 100ppm for 20 minutes is the best to treat fish eggs before incubation. The fertilization rate of eggs, hatching rate, and survival rate of larva after 5 days of hatching when washing by iodine concentration of 100 ppm was 86.44 ±84%, 96.14 ± 1.05%, 58.65 ± 7.60% respectively.

Abstract

Abstract Coastal areas have become an important part of Indonesia's evolving economy, with a variety of commercial activities taking place. The island of Java has both northern and southern coastal areas, each with its own distinctive characteristics and products. The studies about coastal development through its product value chain are still limited. This study aimed to determine the value chain of fishery products in Java to provide recommendations for enhancing coastal management. For the northern coast, milkfish and ariid catfish from Juwana Coast (Pati Regency, Central Java) were selected, while Whiteleg Shrimp from Mendit Coast and Trisik Coast of Kulon Progo Regency, Yogyakarta were chosen to represent the southern coast. The study involved 48 respondents, including small and medium-sized enterprises (SMEs), farmers, fishermen, wholesalers, middlemen, retailers, restaurants, and consumers. The analysis techniques used in this study included Porter's value chain, Hayami's added value, Return/Cost (R/C) Ratio, and marketing margin analysis. The results of the study revealed that the products followed various channels in the value chain, with longer chains leading to higher prices for the end consumers. The findings also indicated that processed and creatively packaged products tend to command higher prices and generate greater profits. Coastal management should not only focus on upstream activities but also consider downstream processes to increase the value of coastal products. Efforts to enhance coastal management should consider key actors and government interventions through developing the coastal local products. Highlight Research The coastal area of Java Island makes a significant contribution to the local economy. The supply chain of Whiteleg Shrimp, Ariid Catfish, and Milkfish involves various actors who play important roles in maintaining the distribution of coastal products. Value chain analysis reveals opportunities to increase and improve the quality of products to enhance their worth. It is necessary to enhance coastal management by involving local institutions, the government, and the private sector.

Abstract

Abstract The social structure of inland fisheries communities tends to place powerful elites in important positions, while local fishermen are subordinate actors. Patronage is a form of social relationship that describes the unequal social structure between these actors. This research aimed to analyze social structure in the inland waters of South Sumatra in the practice of the Lebak Lebung and River Auction (L3S) in OKI District. To achieve this goal, a constructivist paradigm with qualitative research methods was employed, and the sample comprised 39 informants selected as subjects. The data analysis was conducted in three distinct stages, namely data reduction, presentation, and drawing conclusions. The results showed that the regulation of open access for all parties in the local government regime after 1982 created an institutionalized social relations structure where the government, investors, traders, middlemen, and non-fishing actors dominated compared to the fishermen. The participants in this social landscape strived to accumulate capital to enhance their competitiveness within the L3S domain. A patronage system was implemented with middlemen assuming the role of patron and the fishermen acting as their clients. The current institutional social structure has created an unfair distribution of resource benefits for fishing workers. The novelty theories were found in the working relations of the inland waters community of South Sumatra, namely stratified distribution of rights, dual status, multi-stage patronage, and the positive function of patronage for chief fisherman. Further research should be conducted to research policy revitalization and develop strategic inland water management models. Highlight Research The author mentioned 3 highlights from their results research: Auction system in inland waters in South Sumatra presents an unfair distribution for fishermen. Structure of the working relationship formed is an asymmetric patron-client relationship but with novel theories such as the stratified distribution of rights model, dual status, multi-stage patronage, and the positive function of patronage. An imbalance in local access to auction objects due to their weak ability to accumulate capital.

Abstract

Abstract The common technique of traditional salt production in Indonesia is seawater evaporation technology, which uses sunlight to produce salt crystals from seawater. However, in general, the applied technology only produces salt with about 80% NaCl and water contents >7%, impurities >2%, and other contaminants. This produced salt is not suitable to be used as industrial salt. This study aimed to determine the effects of liquid organic fertilizer Gracilaria sp. addition into the culture media of Tetraselmis chuii on Artemia sp. growth, to identify the profile of length, weight, and survival rate of Artemia sp., and finally attempted to uncover the contribution of Artemia sp. in impurity mineral absorption and NaCl content improvement. The results of the study showed that the density of T. chuii based on the concentration of liquid organic fertilizer Gracilaria sp. was significantly different (p<0.05) in each treatment. T. chuii cultivation using liquid organic fertilizer Gracilaria sp. 16 mg N/mL resulted in the highest density on the culture days. However, the studies showed that there was no significant effect (p>0.05) on the weight and length gain of Artemia sp. The research conducted can support the downstream use of products from engineering research in the field of technology to increase the added value of salt products and be part of the contribution to the achievement of the 14th SDG on life below water. Highlight Research Integration of chuii and Artemia sp. culture in salt production could improve NaCl contents by up to 97% and reduced impurities of sulfate and magnesium. The result of the first phase of this study is the density of chuii. This finding is useful to find out the effects of Gracilaria sp. liquid organic fertilizer administration as a source of nitrogen that improves the growth of T. chuii. The highest density of T. chuii resulted from a treatment receiving the dose of 16 N mg/L Gracilaria sp. liquid organic fertilizer with > 5 x 106 cells/mL. This finding indicates that the administration of 16 N mg/L Gracilaria liquid organic fertilizer into the culture medium provided a source of nitrogen and phosphorus for the metabolism of T. chuii. The results of the mineral content test on Artemia sp. show the largest percentage change in Mg2+ > SO42- > Cl- > Na+. The densities of Artemia sp. showed a positive trend of increasing levels of Mg2+ and SO42-, which coincided with decreasing levels of Mg2+ and SO42- in seawater media. The results of NaCl content measurement in water with Artemia sp. culture integration show salt with excellent quality of 97% that met the criteria of industrial salt. The contribution of Artemia sp. to improving the quality of salt products is interesting and has the potential to serve as an alternative to the traditional salt-farming system that is currently practiced.
