Abstract

Highlight ResearchThe leopard coral grouper Plectropomus leopardus was identified and analysed based on molecular approach.Genetic diversity within two regions in Gorontalo, Sulawesi successfully performed using connectivity analysis.Three haplotypes of Plectropomus leopardus from two region in Gorontalo as one of economical important marine fish species. AbstractBar-cheek coral trout (P. leopardus) is the flagship of the grouper in the live fish market in Asia. Unfortunately, the potential of the grouper is still partly produced from natural catches. Even though hybridisation activities have also started to be carried out, there still have not been many studies on the genetic diversity of these fish. The application of molecular identification has been widely applied in marine aquatic animal species, which are very likely to occur due to errors in terms of shape and colour in the morphological character. DNA information has been beneficial in efforts to the breeding program and develop grouper aquaculture activities. DNA barcoding was used for the molecular identification and haplotype analysis of P. leopardus from two locations in Gorontalo, Sulawesi, Indonesia. A total of 14 fish samples were collected from two traditional fish markets around Kwandang and Sumalata Gulf in the northern part of Gorontalo Province, Sulawesi. This study identified and found three haplotypes from both regions. Molecular identification using Cytochrome c Oxidase subunit I (COI) gene region on mitochondrial DNA. Besides Mega7 for phylogenetic reconstruction, the data analysis using DnaSP6, Arlequin Ver.3.5.2.2, and Network 5.0.1.1. The first Haplotype is a mixed population between the Kwandang Gulf and the Sumalata Gulf, then the Kwandang Gulf haplotype and the Sumalata Gulf haplotype. The genetic distance between Kwandang Gulf haplotype and Sumalata Gulf haplotype is 0.003984, classified as a shallow genetic distance and needs more samples from another region to figure out leopard coral grouper around Indonesia.

Abstract

Highlight Research The sound of d spiny  lobster (Panulirus homarus) was identified, named rasp; slow rattle; and popping sound The sound characteristics of  spiny  lobster (Panulirus homarus) represent its behavior Passive acoustic and visual record method combination was implemented to analyze the relation between sounds and behavior of  spiny  lobster (Panulirus homarus)   Abstract Spiny lobster Panulirus homarus is one of many important economic fishery resources in Indonesia. Continuous exploitation activities in the natural habitat can potentially disturb the sustainability of lobster resources. This species is known to produce sound with certain characteristics and highly dependent on environmental changes. This study aimed to investigate the characteristics of sound as a representation of behaviour. The sound produced by P. homarus was recorded for 24 hours using a hydrophone (a passive acoustic technique). The hydrophone converts the sound wave produced by the lobsters into electric voltage in millivolts, then were converted to a digital number, in order to be saved in a virtual format with the *.wav extension. The video system captured data on behaviors of resting, territoriality, aggression, and social attitudes. The results showed that P. homarus emitted rasp, slow rattle, and popping type of sound, with certain characteristics. All sounds types were characterized by a broadband frequency (4 - 20 kHz), and a source level ranging from 125 - 145 dB re 1 µPa. Rasp sound consisting of 12 - 40 pulses with a sound duration of 100 - 400 ms, represents a defensive behavior. Slow rattle sound with 2 - 7 pulses did not represent a specific behaviour and it is dominant during the night. However, the popping sound with only one pulse represented feeding behavior.

Abstract

Highlight Research New method to synthesis nano chitosan from Vannamei shrimp with high Deacetylation Degree Nano chitosan from Vannamei shrimp can adsorb heavy metal Fe up to 81.35% Shrimp shells as an alternative adsorbents for Fe   Abstract Shrimp cultivation produces shrimp wastes in several forms, including shells from the molting process. Shrimp shell waste can be used as a source of nano chitosan. Many researches have used nano chitosan for various applications, one of which is to adsorb heavy metal pollution. This present study aimed to extract chitosan from shrimp shells and investigate the ability of nano chitosan to adsorb Fe metal. The research began by isolating chitin and chitosan from shrimp shells through deproteinization, demineralization, and deacetylation. The obtained chitosan was afterward characterized using Fourier Transform Infrared (FTIR). Furthermore, the glassy ionic method was used to synthesize nano chitosan. Nano chitosan was characterized using a scanning electron microscope (SEM), and the Fe metal adsorption ability was measured using Atomic Absorption Spectroscopy (AAS). The FTIR results showed that the synthesized shrimp shells had successfully formed chitin compounds with the appearance of the C-O-C functional group, while the chitosan compounds with the appearance of O-H and N-H groups. The SEM characterization showed that nano chitosan with a size of 173.71 nm was successfully formed with identical morphology in the form of a flat (spherical), elongated, and irregular position. The nano chitosan was able to absorb Fe solution up to 81.35%. Therefore, nano chitosan from the shrimp shells is suitable as an adsorbent of heavy metal Fe.

Abstract

Highlight Research Based on technological and economic dimensions, the sustainability of seaweed cultivation in Ekas Bay was less sustainable (index value lied between 26 and 50). The distance between seed clumps, drying places, seedling binding locations, and warehouses were the most sensitive attributes from technological dimension. Market status, market scale, and target market were the most sensitive attributes from economic dimension   Abstract Indonesia is one of the major countries in the world that produces seaweed. West Nusa Tenggara has become one of the centers of seaweed producers in Indonesia because it has many bays that are used for seaweed cultivation activities. The problem of seaweed aquabusiness is the low productivity of the production unit managed by seaweed farmers. This study aimed to assess the effectiveness and production level of seaweed cultivation technology and the success of seaweed cultivation by seaweed farmers in Ekas Bay based on technological dimensions (17 attributes) and economics (14 attributes). The Rapsewaqua application is used to analyze the sustainability status of seaweed cultivation. Based on the results of the analysis, the index value was 50.08 for the technology dimension and 39.50 for the economic dimension. The result showed that the sustainability of seaweed in Ekas Bay was in the less sustainable category. Spacing between seed clumps, drying area, seedling binding location, and warehouse were the most sensitive attributes on the technological dimension. Market status, market scale, and target market were the most sensitive attributes in the economic dimension. These sensitive attributes need to be improved to support the sustainability of seaweed in Ekas Bay.

Abstract

Highlight Research Brown seaweed heavy metals content varies between species Risk assessment showed low health risk for heavy metal from intake of the three brown seaweed The three types of brown seaweed did not show carcinogenic properties to metal Arsenic (As) Abstract Marine brown seaweed are known as one of the potential biological agents to be developed as functional food and medicinal sectors. This study aims to examine the concentration of heavy metals (Pb, Cd, Hg, and As) in brown algae (Sargassum aquifolium, Padina australis, and Turbinaria ornata.) and the possible exposure to health risks caused by consumption.  Heavy metal concentrations were determined using Atomic Absorption Spectroscopy (AAS) on brown seaweed samples obtained from three different sites. The average concentration of heavy metals in the dry weight of brown seaweed remains within the guidelines established by The Food and Drug Supervisory Agency (BPOM) Number 32 of 2019 concerning the Safety and Quality of Traditional Medicines, which is then used to calculate the estimated daily intake (EDI), target hazard quotient (THQ and TTHQ), and target cancer risk (TCR) for arsenic associated with food exposure to potentially toxic metallic elements. Each species of brown seaweed has a THQ and TTHQ level of <1, indicating that one or more toxic metal elements in the same meal provide no significant non-carcinogenic risk. The TCR for arsenic in these seaweeds are all less than 1 x 10-4, indicating no cancer risk. There are no chronic health hazards related with the ingestion of brown seaweed harvested from the coast of Sanur Beach at Denpasar, Bali.

Abstract

Highlight Research First NR-SOB from Indramayu coast was successfully isolated and identified. Bactrerial characterization morphologically and biochemically, foster with in situ hybridization confirm the isolate was Thiobacillus denitrificans, and Arcobacter sp. Both isolate, Thiobacillus denitrificans and Arcobacter sp., were able to grow in sulphide rich environment in the presence of essential nutrient Thiobacillus denitrificans and Arcobacter sp. exhibit an outstanding sulphide oxidation ability up to 100% in the presence of nitrate.   Abstract Crude oil production triggers the formation of hydrogen sulphide, also known as souring, which is extremely toxic and corrosive to the environment. It additionally give an adverse consequence to aquatic, terrestrial, and human existence. Studies of hydrogen sulphide reduction in sediments polluted by crude oil have been carried out recently to investigate the capability of indigenous Nitrate-Reducing Sulphide Oxidising Bacteria, hereinafter referred to as NR-SOB, as bioremediation agents. The experiments utilised hydrogen sulphide with 200 µM concentration combined with NO3 with different concentrations of 100 µM, 200 µM, and 300 µM. Measurements of the hydrogen sulfide concentrations were observed up to 48 hours within the experimental period. The SOB used in this study were taken from Balongan Bay at Indramayu coast using Nansen bottle to carry out water sample. The sulphide-oxidising ability of SOB was then evaluated at room temperature in control environment. Methylene blue method was applied to monitor the sulphide concentration. The results showed a complete removal of hydrogen sulphide concentrations in 48 hours accompanied with gradual drops of nitrate in all experiment series. Sulphide oxidation rate was detected to appear between 6.8 and 10.2 fmol/cell/hour. Measurements of cell abundance after 48 hours showed 6.2 x 105, 7.5 X 105, and 8.2 X 105 cell/ml from Experiments I, II, and III respectively. Using MSS selective medium, the bacteria were identified as Thiobacillus denitrificans and Arcobacter sp. Overall, the isolated NR-SOB from the coast of Balongan Bay, Indramayu proves to be a promising candidate for sulphide controls and mitigation.

Abstract

Highlight Research Experimental use of pre-treated pangasius skin as collagen raw material using different acetic acid immersion time Effects of immersion time on the yield of collagen from pangasius skin Effects of immersion time on the proximate content of collagen from pangasius skin Presenting SDS-Page profile of collagen from pangasius skin   Abstract Pangasius sp. production in Indonesia has reached 384,310 tons in 2019. One of the main waste in pangasius fillet industry is the skin, which reached to 6% of body mass. Fish skins are alternative for making collagen because it has no restrictions for certain religions and ethnicities. Collagen is a protein biomaterial which acts as the main component of connective tissue. Extracting collagen using organic acids such as acetic acid is the most common extraction method. Herein, we report the effects of different immersion time of acetic acid to collagen properties from pangasius skin. In this study, pangasius skin was treated using 10% alcohol with the ratio 1:10 (w/v) for defatting and 0.1M NaOH with the ratio 1:10 (w/v) for eliminating non-collagenous protein. The immersion of 0.5M acetic acid was carried out on pangasius skin with the ratio of 1:20 (w/v), for 24, 48, and 72h at temperature less than 15oC. The sample was salted-out for 24 hours with NaCl until the concentration reached 2.5M, then the sample was freeze-dried at -40oC. This study investigated that longer immersion time affected the properties of pangasius skin collagen. Different immersion time significantly affected the yield of collagen from pangasius skin (p<0.05). Pangasius skin has a potential to be used as collagen raw material, and 72h of immersion time (P3) is suggested to produce pangasius skin collagen with the highest yield and protein content (6.15 % and 9.26 %). Production of collagen from the fish skin will contribute to increase pangasius waste valorization in pharmaceutical industry.

Abstract

Highlight Research The present of microplastics is more than macroplastics on the Pasir Pandak Beach The existence of huge amount of smaller microplastics (<0.50 mm) were observed on this beach sediment Types of macroplastics found are fragment, foam, and fiber; while microplastics are fiber, filament, fragment, and foam The main polymers found are HDPE, PES, PP, and PS Clean Coast Index indicated Pasir Pandak Beach as an extremely dirty beach   Abstract Pasir Pandak Beach is close to human settlements, resorts, and food stalls. It becomes a place for gathering of beachgoers especially during weekend. As a result, the beach became polluted with rubbish, particularly plastics (e.g., macro- and micro-plastics). Hence, this study was done to determine the occurrence of macro- and micro-plastics on the Pasir Pandak Beach, Kuching, Sarawak, Malaysia. Transect quadrat was used during the samples collection on the beach. The samples were then undergone the wet peroxide oxidation, filtering and classifying under dissecting microscope. Macroplastics were isolated for ATR-FTIR and SEM analyses, while microplastics were separated according to their sizes, colors, and types. Approximately 101.70 items/m2 of macro-plastics and 1084 items/m2 of micro-plastics were found in this study. Clean Coast Index (CCI) was also estimated and the calculated CCI value obtained was >20, which indicated as extremely dirty beach. Fragments of carpet/canvas/mat and hardware crate/item were the most abundance macroplastics found, followed by plastic ropes/fishing lines and bottle caps. HDPE, PES, PP, and PS were the main identified polymers. Fibers, filaments, fragments, and foams were identified for micro- and macro-plastics. Microplastics with smaller sizes of 0.25-0.50 mm were available abundantly and they comprise 63.47 % of the total microplastics found. Clear/white, black, and blue were the main colors for microplastics. SEM images presented that those adhering particles, grooves, pits, fractures, and flakes were the common patterns of degradation. No relationship was apparent between macro- and micro-plastics at each station. The abundance of macro- and micro-plastics showed that they were mainly controlled by the land-based input. As Pasir Pandak beach is busy with local communities and beachgoers, the presence of macro- and micro-plastics on the beach posing a severe threat for marine environment, thus further studies on the behavior of this emerging pollutant from beach to the seas are necessary.
