Abstract

Graphical Abstract   Highlight Research Water-soluble chitosan from crab’s shell can be produced via the pressurized hydrolysis method in an acidic environment with a pressure cooker; the optimal treatment is a 3% HCl concentration. Water-soluble chitosan from crab’s shell has the following properties: it is yellowish white in color, odorless, powder-like, with a yield of 83.37±0.73, an acidity degree of 5, 83±0.34, viscosity of 69.0±0.82, solubility of 93.57±0.33, and a degree of deacetylation of 78.4%. The optimal concentration for water-soluble chitosan from crab’s shell inhibition is 160 mg/ml, with an inhibition zone of 7.47 mm for S. aureus and 6.70 mm for E. coli, falling in the medium category. Physical features of organoleptic water-soluble chitosan from crab’s shell hand sanitizer: neutral appearance (5), somewhat similar fragrance (6), neutral texture (5), similar (6), not homogenous, dispersion 3.59-4.03 cm, pH 6.05-6.28. The most effective hand sanitizer formulation from crab’s shell water soluble chitosan is HS3 (including 200 mg/ml of water-soluble chitosan), which has a weak inhibition zone of 5.35±0.57 mm for S. aureus bacteria and 4.70±0.07 mm for E. coli.       Abstract There has been no research on the application of water-soluble chitosan (WSC) derived from crab shells as a hand sanitizer. using a pressurized hydrolysis method. The limited solubility of chitosan at neutral pH restricts its usability. The aim of this study was to produce WSC from crab shells using pressurized hydrolysis methods as an active ingredient for hand sanitizer. Chitosan was depolymerized into WSC by utilizing hydrochloric acid (2, 3, and 4%) and was hydrolyzed using a pressure cooker at a temperature of approximately 110˚C for 1 hour. Isopropyl alcohol was then added to the filtrate at a ratio of 2:1. The selected WSC was treated with 3% HCl and made into 3 different concentrations of 140, 150, and 160 mg/ml, then tested for its antibacterial activity. The WSC hand sanitizer antibacterial test has concentrations of 180, 190 and 200 mg/ml, and for positive control using commercial hand sanitizer, and negative control in the form of basic gel without chitosan. By depolymerizing chitosan using 3% HCl, a high solubility (93.57±0.33) of WSC was achieved, with a degree of deacetylation (DD) value of 78.4%. The results indicated that the concentration of WSC is160 mg/ml and exhibited the strongest inhibition against S. aureus and E. coli, with clear area values of 7.47 mm and 6.70 mm, respectively. The best hand sanitizer formulation is HS3 (in addition of WSC 200 mg/ml) and the ability to inhibit S. aureus bacteria with a clear area value of 5.35 ± 0.57 mm and E. coli is 4.70 ± 0.07 mm. This study shows the potential of WSC from crab shells as a sustainable and effective antibacterial active ingredient in hand sanitizers, which requires further research on scalability and wider applications.

Abstract

Graphical Abstract Highlight Research vB_Vp_TSK01 and vB_Vp_JKT02 a specific parahaemolyticus bacteriophage were isolated from the shrimp aquaculture water. Compared to control vB_Vp_TSK01 reduced 11.46±1.35% of bacterial growth, and by 9.86±5.92% for vB_Vp_JKT02 treatment. Their cocktail had the highest parahemolyticus growth inhibition by 30.92±3.89%. The phage treatment increased the survival of the Artemia by 28.57% compared to infection control.     Abstract Acute Hepatopancreatic Necrosis Disease (AHPND) caused by V. parahaemolyticus infection was one of the major diseases in shrimp culture in recent years. The Vibrio could also affect the survival of Artemia as the shrimp’s main live feed in the hatchery and they become the possible carrier for the AHPND. Phage therapy in shrimp aquaculture could reduce the application of the antibiotic as an antibacterial agent for the AHPND. The present study aimed to isolate the specific lytic phage for the Indonesian strain of V. parahaemolyticus (Vp) and evaluate the phage therapy for the brine shrimp Artemia infected with the Vp. The Vp-specific phage was isolated from the shrimp farm’s water at Tasikmalaya, and North Jakarta City, Indonesia. After isolation and plaque assay, brine shrimp were used as a model to evaluate the phages’ anti-Vibrio activity The Vp-lytic phage was successfully isolated from shrimp culture water at North Jakarta and Tasikmalaya (Vb_Vp_TSK01 and Vb_Vp_JKT01, respectively) and the results showed that both isolated phages and their cocktails were capable to inhibit the growth of Vp with the highest inhibition shown at the cocktail treatment (p<0.05). The survival of Artemia was higher in the phage treatments (p<0.005) compared to the infected control. Infected control had 68.33% of brine shrimp survival, and the Vb_Vp_TSK01, Vb_Vp_JKT01, and their cocktail had similar average brine shrimp survival of 91.11%. In conclusion, phage therapy proved effective in preventing vibriosis in brine shrimp under the conditions tested.

Abstract

Graphical Abstract   Highlight Research Lola snails originating from the Bangka Belitung Islands (Nasik Strait, Rebo Waters, and Ketawai Island) were identified as a maxima not to be R. nilotica species based on morphological molecular identification. Maxima and R. nilotica have the same morphological form, but they are genetically different. The clarification of the Lola snail species in this study serves as a reference in determining the conservation status of the Lola snail. The clarification of the Lola snail species serves as a reference in determining the catch quota from the Bangka Belitung Islands.     Abstract The use of Lola snails (Rochia maxima) in the Bangka Belitung has continued to increase. However, research focused on Lola snails originating from the Bangka Belitung has not been thoroughly conducted. In a previous study, the Lola snail sample found in the Bangka Belitung was Trochus niloticus (current name: Rochia nilotica). This study aimed to identify Lola snail species using the DNA barcoding as a way of clarifying Lola snail species that originated in the Bangka Belitung. Lola snail sampling was carried out at three locations, which were Nasik Strait, Ketawai, and Rebo Waters. This study was conducted through five stages, including Lola snail tissue sampling, DNA extraction, amplification by PCR, sequencing, and data analysis. The results showed that the molecular identification of the Cytochrome Oxidase Subunit 1 (COI) gene in Lola snail samples was identified as Rochia maxima species (Koch, 1844). The results of the phylogenetic tree analysis showed that Lola snails found in the Bangka Belitung were close to Tectus maximus (or Rochia maxima) species. R. maxima has a lighter shell than R. nilotica, a clear conical shape, and a circle on the body that does not widen at the edges. Unlike zoologists who said that R. maxima is the primitive form of R. nilotica, the present study found that they have the same morphology and are considered similar but genetically different. The clarification of Lola snail species can be used to determine the conservation status and catching quota of Lola snails from the Bangka Belitung.

Abstract

Graphical Abstract   Highlights of Research The chitosan was successfully produced from lobster shells Panulirus homarus. The characteristics and quality of chitosan from lobster shells Panulirus homarus were observed. The anti-fungal activity of chitosan was assessed. Chitosan enhances the water stability of lobster pellets.       Abstract Tropical rock lobster aquaculture is a lucrative industry that is currently limited by the lack of appropriate formulated feed. Its nocturnal, benthic feeding behavior necessitates a water-stable feed that maintains integrity under tropical marine conditions without degrading. Chitosan, a biopolymer derived from lobster (Panulirus homarus) shells, has potential applications in aquaculture as an antifungal agent and feed binder. We report on the characteristics of chitosan extracted from the exoskeleton of spiny lobsters (Panulirus homarus), including its effect on fungal activity and water stability of pellets. Chitosan was produced through three main steps: deproteination, demineralization, and deacetylation. The resulting chitosan was characterized through crude composition (AOAC methods), FTIR spectra, and scanning electron microscope (SEM), while antifungal activity was assessed through in vitro assays. Chitosan was used to coat lobster feed pellets by immersion method at different concentrations (0%, 0,5%, 1%, 1,5%, and 2%), and its impact on pellet water stability was assessed. There were three replications in fungal activity and water stability test. The yield of chitosan was 5.9 ± 0.01% of the total shell mass, with 96.99% ± 0.01 degree of deacetylation (DD). The resulting product contained 5.94 ± 0.07% moisture, 36.72 ± 0.05% ash and 2.73 ± 0.08% nitrogen. Chitosan morphology was characterized as an irregular shape with dimensions ranging from 157 to 391 µm, with a combination of striated surface textures. Increasing concentration of chitosan increased water stability of pellets up to 1.5% inclusion, while 0.5% optimized Fusarium sp. inhibition. These findings suggest that chitosan from lobster shells can be sustainably utilized to enhance feed quality, reducing fungal contamination and nutrient leaching in aquaculture systems.

Abstract

Graphical Abstract   Highlight Research DNA Barcoding and Species Analyzed: Tissue samples from 11 individuals across five shark species and two ray species were analyzed using DNA barcoding. The species include Sphyrna lewini, Carcharhinus sealei, Stegostoma fasciatum, Galeocerdo cuvier, Carcharhinus falciformis, Rhynchobatus australiae, and Rhina ancylostoma. Genetic Similarity and Divergence: Results showed high genetic similarity within species, but some divergence was observed between different populations, indicating potential evolutionary or geographic separations. Phylogenetic Relationships: The phylogenetic analysis revealed seven distinct clades, providing insight into the evolutionary relationships of these species. Conservation Implications: Several species identified in the study are protected, such as lewini, G. cuvier, and C. falciformis. The study underscores the importance of incorporating genetic diversity data into conservation strategies to protect these ecologically vital species in Indonesia.     Abstract Sharks and rays, as apex predators or mesopredators, help maintain marine biodiversity and ecosystem balance. Their ecological and economic value underscores the need for conservation, as they face threats from overfishing, habitat loss, and climate change, with many classified as vulnerable or endangered by the IUCN. This study investigates the genetic diversity and phylogenetic relationships of sharks and rays in Bawean and Masalembu Waters, East Java, using morphological identification and DNA barcoding. The specimens were obtained from fishermen operating in Bawean and Masalembu Waters     . A total of 11 samples were analyzed from five shark species: Sphyrna lewini, Carcharhinus sealei, Stegostoma fasciatum, Galeocerdo cuvier, and Carcharhinus falciformis, and two ray species: Rhynchobatus australiae and Rhina ancylostoma. Results showed high genetic similarity within species, with some divergence observed between samples from the Bawean and Masalembu regions. For instance, populations of Sphyrna lewini from the two regions exhibited slight mitochondrial DNA sequence variations, indicating possible adaptations to local environmental conditions. Similarly, genetic differences in Rhynchobatus australiae suggest limited gene flow between populations, likely influenced by geographical barriers or habitat preferences. Phylogenetic analysis revealed seven distinct clades, highlighting evolutionary relationships such as the close grouping of S. lewini and G. cuvier, which suggests recent divergence. Several species identified, including S. lewini, G. cuvier, and C. falciformis, are protected, underscoring the need for stricter conservation and monitoring efforts to safeguard shark and ray populations. This study highlights the urgency of integrating genetic diversity into conservation strategies to ensure the long-term survival of these vital species.

Abstract

Graphical Abstract   Highlight Research DSAS based on geographic information systems has the ability to extract important information on the dynamics of shoreline changes, both accretion and abrasion. The dynamics of shoreline change in the short period of time 2018-2023 in the IWIP industrial area shows a very dynamic change process dominated by accretion. The conversion of beach into land was more prevalent than the process of shoreline retreat in the study area. The abrasion rate in this study area was categorized as moderate, while the accretion rate was categorized as very high due to construction activities.     Abstract The development of industrial estate infrastructure in coastal areas causes significant changes in coastal morphology. Despite extensive infrastructure development in coastal zones, limited empirical data exists on the shoreline dynamics of newly established industrial estates, particularly in Eastern Indonesia, thus highlighting the urgency of this study. This study investigates coastal morphology changes in the PT Indonesia Weda Bay Industrial Park (IWIP) industrial area over five years using Landsat 8 OLI level 2A satellite imagery and geospatial analysis. Shoreline extraction was performed using the Normalized Difference Water Index (NDWI) algorithm and analyzed with the Digital Shoreline Analysis System (DSAS) applying the Net Shoreline Movement (NSM), End Point Rate (EPR), and Linear Regression Rate (LRR) methods. The findings show that from 2018 to 2023, the shoreline in the PT IWIP area predominantly experienced accretion. The highest rate of shoreline accretion occurred in industrial zone, with a maximum of 147.58 m/year and an average of 36.56 m/year, while residential zones in the eastern and western regions experienced moderate abrasion, with a maximum of 12.32 m/year and an average of 4.11 m/year. Categorization followed standard DSAS criteria, where shoreline changes between 10–30 m/year were considered moderate, and changes above 30 m/year were classified as very high. Measurement accuracy was validated using high-resolution Google Earth imagery and Landsat metadata, ensuring positional accuracy within ±30 meters. These results highlight the rapid and spatially varied shoreline changes driven by industrial activities, emphasizing the importance of remote sensing in monitoring and managing coastal development impacts

Abstract

Graphical Abstract   Highlight Research The grass carp was the species used in this study due to its ecological significance and sensitivity to pollutants. The study examined both acute and chronic toxicity effects of pesticides on grass carp to understand their immediate and long-term impact. Harmful effects on hematological profile of Grass carp fish were observed and hence are deleterious to aquatic life and environment. Biochemical changes observed, Emamectin Benzoate found more toxic than Acetochlor and Acetochlor is more toxic than Topsin-M.     Abstract This study investigates the novel combined effects of Emamectin Benzoate (pesticide), Acetochlor (herbicide), and Topsin-M (fungicide) on hematological and biochemical profiles in grass carp (Ctenopharyngodon idella), to fill critical gaps in understanding their ecotoxicological impacts on aquatic health and sustainable fisheries. Fishes from farm in Gujranwala were acclimatized in a freshwater aquarium laboratory for a week, then divided into four groups (E1, E2, E3, and E4) exposed to pesticide, herbicide, and fungicide concentrations for 5 and 14 days. Blood samples were collected for hematological and biochemical parameters. Exposure to Emamectin Benzoate induces significant increase in WBCs, neutrophils, MCV, MCH, and platelets, while a significant decrease was found in RBCs, lymphocytes, hemoglobin, PCV, and MCHC concentration. Acute toxicity of Acetochlor showed an increase in WBCs, neutrophils, MCV, MCH contents, and platelets, while a decrease in RBCs, lymphocytes, hemoglobin, PCV, and MCHC contents was noted. Effects of Topsin-M showed an increase in WBCs, neutrophils, MCV, MCH contents, and platelets. However, a significant decrease in RBCs, lymphocytes, hemoglobin, PCV, and MCHC contents has been observed. It reveals that Uric acid, serum lipase, Sodium, Phosphorous, Bilirubin, and Potassium increased significantly. Exposure to chemicals induced significant declines in the levels of Lactate dehydrogenase (LDH), Triglyceride, HDL Cholesterol, SGPT (ALT) Creatinine, and ALK Phosphatase which caused illness in fish. This study shows potential for biomonitoring of aquatic environments.

Abstract

Graphical Abstract   Highlight Research 1. Sargassum polycystum has been extracted and analyzed. 2. Cytobacillus kochii GSD in response to fucoidanase-producing enzyme activity was analyzed. 3. Optimum temperature, pH, and salinity can suppress the activity of the fucoidanase enzyme through the inhibition test. 4. Cytobacillus kochii GSD can produce fucoidanase enzyme with low molecular weight.     Abstract Extensive research has shown that low molecular weight fucoidan exhibits significantly greater biological activity than its high molecular weight. C. kochi GSD, a Sargassum symbiont bacterium, is proven to have the activity of hydrolyze fucoidan. This study proposes the growth optimization and fucoidanase enzymatic activity of C. kochii GSD bacteria under varying environmental conditions (temperature, pH, and salinity) cultured in basic liquid medium (BLM) for 48 hours. Based on Response Surface Methodology (RSM), the range of temperature, pH, and salinity for the growth optimization test of C. kochi GSD bacteria were 26.591, 30, 35, 40, and 43.49oC, the pH used starts from 3.636, 5, 7, 9, and 10.363, while the salinity to be used starts from 3.522, 5, 17.5, 30, and 38.522 ppt, respectively. The best conditions for growth of each environment were then continued with the test of fucoidanase enzyme activity in vitro. The results showed that C. kochii GSD bacteria grew optimally at temperature, pH, and salinity of 35oC, 7, and 30 ppt, respectively. The optimum enzyme activity of C. kochii GSD is at 72 hours with the forming of clear zones on media containing fucoidan and given Cetylpyridinium chloride (CPC) solution with clear zone diameters of 31.17 mm (temperature), 25.9 mm (pH), and 20.97 mm (salinity), respectively. The conclusion of this study is a high novelty finding to produce low molecular weight fucoidan enzymatically with C. kochii GSD bacteria to be used as an immunostimulant.
