Abstract

Highlight Research 1. There were 26 active compounds from water clover leaf extract that were identified using GC-MS 2. In silico approach was used to screen potential anticholesterolemic compounds from water clover leaf extract 3. Anticholesterolemic compounds from water clover leaf extract were interacted with HMG-CoA reductase receptors and compared to native ligand and medicine 4. There were 6 potential anticholesterolemic compounds identified from water clover leaf extract   Abstract   Water clover (Marsilea crenata C. Presl.) is a widely available plant in Indonesia and often utilized as a traditional food ingredient. This plant is also traditionally believed to contain compounds that can decrease blood cholesterol. This study aimed to determine the compounds in water clover which have the potential to decrease blood cholesterol through inhibition of the HMG-CoA enzyme using in silico approach. This research was done in several steps, i.e., extraction using ethyl acetate solvent, identification of chemical compounds using GC-MS, and screening of compounds with potential to be  anticholesterolemic agent through in silico using PyRx 0.8 (AutoDockVina and  Open Babel GUI version 2.4.1), Discovery Studio Visualizer 2021, and PyMOLâ„¢ 1.7.4.5 software. Results showed that ethyl acetate extract of water clover contained 26 compounds, 6 of which were potential to be anticholesterolemic agent, i.e., phytol, 1,2-benzenedicarboxylic acid, 2,4-di- tert-butylphenol, diethyl phthalate, 1,2,3,4-tetramethylbenzene, and dipentene. Binding affinity values of those six compounds were lower than the native ligand of the HMG-CoA reductase, although still higher compared to pravastatin. The binding affinity value of pravastatin was -7.13 kcal/mol and the binding affinity value of 3-methyl glutaric acid as a native ligand was -5.33 kcal/mol, meanwhile, the lowest binding affinity value of compounds in water clover was phytol (-6.37 kcal/mol) and the highest was dipentene (-5.40 kcal/mol). Through in silico study, there were six compounds from water clover leaf's ethyl acetate extract that could inhibit the HMG-CoA reductase. Therefore, water clover leaf has the potential to become an anticholesterolemic functional food ingredient.

Abstract

Highlight Research Seeds can grow into seagrass seedlings for an optimal period of five weeks Seed sowing can be optimized by supplementing nutrients with fertilizers The seedling transplant method, which utilizes seed seedlings, is not significantly different in daily growth from the anchor transplant method, which utilizes donors/seeds transport The biomass content of seagrass leaves can be used to determine the growth rate of the leaves Abstract Globally, the area of seagrass beds important to the ecosystems in coastal environment is decreasing due to environmental pressures, both natural and artificial. Transplantation is one way to restore the condition of damaged seagrass beds, the anchor transplant method uses the transfer of donor seagrass to the transplant area, while the seed transplant method uses seed sowed from seagrass. This study aimed to investigate the survival and growth rates of seagrass transplants and the biomass and chlorophyll content of transplanted Enhalus acoroides in the waters of Panjang Island Jepara utilizing anchor and seedling methods. The research was conducted in the waters around Panjang Island, Jepara, between September and December 2021. The results indicated that transplantation of seagrass E. acoroides using the anchor method resulted in the highest average growth rate of 0.25 cm/day and a survival rate of 96.67%, while transplantation using the seedling method resulted in a growth rate of 0.18 cm/day and a survival rate of 83.33%. The results showed that the anchor method scored better than the seedling transplantation method in terms of growth rate and survival rate. However, seedling is a feasible method to meet the availability of seeds that will later be transplanted, considering that the anchor method still has shortcomings in terms of the availability of seeds and the use of pegs which are still not environmentally friendly. so that the seedling method can be recommended for the restoration process of seagrass ecosystems by taking into account the season, weather and other important indices.

Abstract

Highlight Research The current condition coverage percentage of coral reefs in the waters of Gosong Island was 55% Percentage of dead coral with algae founded on Gosong Island is 28% On Gosong Island there are 11 families, namely Acroporidae, Agariciidae, Faviidae, Fungiidae, Merulinidae , Mussidae, Dendrophylliidae, Oculinidae, Pectiniidae, Pocilloporidae and Poritidae Abstract The coral reef ecosystem is an important ecosystem; its existence has a very close relationship with the surrounding ecosystem and the reef fish community. The direct and indirect dependence of reef fish on coral reefs has become an important issue at the national and international levels. This study aimed to determine the characteristics of coral reef ecosystem conditions, the percentage of coral growth, identify the types of coral reefs, and the diversity of reef fish species on Gosong Island, Southwest Aceh. Coral reef biophysical characteristics were collected by measuring water quality, calculating the percentage of coral coverage using the Point Intercept Transect (PIT) method, and the abundance of reef fish using the Underwater Fish Visual Census (UFVC) method. The condition of average percentage of coral reefs in the waters of Gosong Island was in a good category (55%), found as many as 31 genera of hard corals included in the line transect. The percentage of base substrate that dominates other than live coral is dead coral with algae (DCA) of 28%. The average abundance of reef fish in Gosong Island waters is 11,260 ind/ha with an average reef fish biomass of 2074,095 kg/yield. The water quality results show good conditions for coral growth in location. Based on the analysis of the structure of the fish community found in the coral reef area, the results showed good results, so the research location became a good habitat for various types of fish associated with coral reef ecosystems on Gosong Island

Abstract

Highlight Reseacrh The study showed that the selected F-4 blue tilapia had a better growth pattern than the control (non-selection) F-4 blue tilapia The difference in performance between the two populations of blue tilapia is an illustration of the genetic improvement that is passed on from parents to offspring as a result of the selective breeding The realized heritability value of the weight character of F-4 blue tilapia in the high category There was an increase in growth in the F-4 blue tilapia population with a positive response to selection   Abstract Breeding program in order to increase genetic improvement in blue tilapia have not been widely carried out at brackish water ponds. This study aimed to evaluate the increase in growth and genetic gain of F-4 blue tilapia from family selection in ponds with 25-30 gL-1 salinity. The parent used for the formation of F-4 is the selected parent F-3 and as a control using the non-selected parent F-3. Spawning was carried out in a full-sib mating design using the family selection method. The ratio of male and female broodstock is 1: 2. Spawning and nursery activities of F-4 blue tilapia are carried out in freshwater. The enlargement test was carried out in the net cage 5m x2.5m x1 m which was installed in the ponds with a salinity of 25-35 g l-1 for 120 days, at a stocking density of 10 fish m-2. At the end of maintenance, a selection process is carried out on the weight traits. Parameters observed included growth, survival, and genetic values. The results showed that the growth and survival in the F-4 blue tilapia population, male and female selected populations, had a higher value than in the non-selected population. The realized heritability value of the population growth character of the F-4 blue fish is in the high category. The difference in the average weight of the selected blue tilapia and the control was equivalent to an increase in genetic value added by 15.06% (male population) and 17.92% (female population).

Abstract

Highlight Research Proximate of Ulva lactuca after cooking treatments were analyzed. The cooking treatments carried out in this study were roasted and boiled-roasted Protein quality such as in-vitro digestibility, protein solubility, and amino acids composition of Ulva lactuca after cooking treatments were analyzed The result showed that boiled-roasted samples had the highest protein content, amino acid score and essential acid index, and predicted-protein efficiency ratio   Abstract Plant-based protein has been increasingly demanded as a sustainable protein source. Sea lettuce (Ulva lactuca) is one of the potential sources as plant protein due to its high protein content. During processing, the sea lettuce is exposed to heat which might affect its nutrition, particularly the protein quality. This study aimed to evaluate two different cooking processes on the nutritional quality of the sea lettuce based on the proximate and protein quality analyses. The samples were raw, roasted, and boiled-roasted sea lettuce. All treatment using temperature 100°C. The protein quality was assessed by in-vitro protein digestibility, solubility, and amino acid profiles. The result showed that boiling treatment followed by roasting treatment had significantly higher protein content, amino acid score and essential amino acid index, and predicted-protein efficiency ratio compared with the value of roasting treatment only. It resulted in protein content of 18.87% (dry basis), amino acid score of 37.96%, essential amino acid index of 79.41% and predicted-protein efficiency ratio of 2.58. Therefore, boiling followed with roasting process is recommended to maintain the nutrition quality of sea lettuce.

Abstract

Highlight Research Autoclaving for 3x3 hours followed by alkaline hydrolysis (3x3AH) may lower nano-calcium particle size into 47.47 nm 3x3AH sample contain 30.73% calcium and 18.37% phosphorus 3x3AH sample created the best calcium solubility (26.14 %) in comparison to synthesized CaCO3 (14.34 %) Grouper nano-calcium powder includes trace quantities of organic content, such as protein and fat, which enhance calcium's solubility.   Abstract Fish bone nano-calcium production may solve two challenges, providing calcium for lactose-intolerant people and recycling bone waste. Fish bone autoclaving prior to extraction reduces fat, denatures collagen, and softens bones but only few researches have compared autoclaving duration with nano-calcium product quality, particle size, and its solubility in in vitro testing. This study studied the influence of autoclaving duration followed by alkaline hydrolysis on nano-calcium characteristics to enhance calcium solubility in in vitro gastrointestinal simulation experiments. The dried grouper (Epinephelus sp.) bone was divided into four groups: 0A (no autoclaving), 3A (3 h autoclaving), 2x3A (double cycle for 3 h autoclaving), and 3x3A (triple cycle for 3 h autoclaving). Each group was followed by alkaline hydrolysis, designated as 0AH, 3AH, 2x3AH, and 3x3AH. The results showed that autoclaving for 3x3 hours followed by alkaline hydrolysis resulted in lowest nano-calcium particle size of 47.47 nm consisting of 30.73% calcium and 18.37% phosphorous. 3x3AH sample created the best calcium solubility (26.14%) in comparison to synthesized CaCO3 (14.34%). In contrast to synthetic CaCO3, grouper nano-calcium powder includes trace quantities of organic contents, such as protein and fat, which enhance calcium solubility. In vivo research should be established to study the bioavailability and influence of grouper nano-calcium powder on bone density.

Abstract

Highlight Research The elvers of Anguilla were identified through the morphological and molecular markers The result of morphological and molecular identification is different The molecular identification helps to confirm the morphological identification Based on this study molecular identification of the elvers of Anguilla found in river estuaries of Central Java is Anguilla bicolor bicolor   Abstract An inventory of the presence and diversity of Anguilla spp. needs to be carried out as a basis for sustainable resource management. Conventional techniques based on morphological characteristics”are often less effective considering the morphological characteristics of Anguilla spp. are very identical and not so many can be observed, especially at the young eel stage. DNA-based molecular identification can be a way to determine diversity and phylogeny for conservation and inventory purposes. This research aimed to determine the diversity and phylogeny of Anguilla spp. obtained at the estuaries of Serayu River in Cilacap, Luk Ulo River in Kebumen, and Jali River in Purworejo in Central Java, Indonesia. A total of 10 samples were taken from each research location were analyzed morphologically, then it is known that there are 4 morphologically different samples at each research location so that a total of 12 samples were taken for molecular analysis. MEGA was used to construct the phylogenetic trees via Neighbour Joining (NJ) algorithms using the Kimura 2-parameter model with uniform rates and obtained by 1000 bootstraps replication. There are four species of Anguilla spp. identified morphologically, namely Anguilla bicolor bicolor, Anguilla bicolor pacifica, Anguilla obscura, and Anguilla australis. The species of Anguilla spp. that is molecularly identified is Anguilla bicolor bicolor with an identity percentage of > 98%. All samples are also known to be related to Anguilla bicolor bicolor identified in other countries.

Abstract

Highlight Research There are 26 species identified to be originated from the bay, which the highest diversity in Indonesia Six species found in Kwandang Bay is showing trends of decreasing populations and two species vulnerable based on IUCN conservation list Growth model and Fulton condition factor determined for 14 species indicates that they live in a good state of well beings in the bay The models and condition factors also reflect the adequate food resources required for grouper growth which makes Kwandang Bay as a good habitat for groupers   Abstract Grouper fishery has been the source of income for 3,700 fishermen in Kwandang Bay. Since 2017, grouper populations in Kwandang have been depleting due to the absence of management. This research aimed to analyze species composition, length-weight relationship, and condition factor of the groupers. Samples were collected from fishers who caught the fish using traps, speargun, and handline. Samples were identified through a method by Heemstra and Randall, while the length-weight relationship was estimated using log-linear regression and t-test. The number of specimens identified during January - December 2021 was 1,571 individuals. Research showed that those samples consisted of 26 species under eight genera. Six species found in Kwandang Bay were showing trends of decreasing populations and two species were vulnerable based on the IUCN conservation list. Length-weight relationship analysis of 14 grouper species resulted in b value ranging from 1.6359 to 3.4417 and R2 ranges from 0.7718 to 0.9858. A significant test at a 95% confident interval showed that 14 species had an isometric growth pattern. Fulton condition factors show that Kwandang Bay is an essential habitat for groupers, and the bay can support the fish growth due to the adequate food availability.

Abstract

Highlight Research The genetic diversity of fish and shrimp from mangrove habitats was relatively substantial, with a heterozygosity of 0.926 and the exception of Langsa samples. AMOVA revealed that the diversity among individuals in the populations were higher compared to those within individuals. DNA barcode in mangroves is useful in developing mangrove conservation and restoration initiatives   Abstract Fish and shrimp are among the species that are vulnerable to high level of disturbance in mangrove ecosystem. This study aimed to investigate the implementation of 16S rRNA gene for fish and shrimp barcoding in mangrove ecosystems in North Sumatra and Aceh, Indonesia. 50 samples fresh fish and shrimp were collected from five mangrove ecosystems in North Sumatra, namely Belawan, Lubuk Kertang, Percut Sei Tuan, and Pulau Sembilan and Langsa of Aceh for DNA extraction process. The research was divided into four activities: sample collection, DNA isolation, PCR amplification, and data analysis. DNA was extracted using kit extraction (kit Reliaprep gDNA Tissue Miniprep System) and with PCR amplification. Genetic parameters were analyzed using Gen Alex 6.51 software and the relationship between sites was examined using the MVSP 3.22. The genetic diversity of fish and shrimp from mangrove habitats was relatively substantial, according to the findings, with a heterozygosity of 0.926, with the exception of Langsa samples, which were only identified in subclass A1. Genetic relationship between sites revealed that all samples clustered into two branches and were randomly dispersed within each site. This work confirmed the 16S rRNA gene worked for fish and shrimp barcoding in mangrove ecosystems, North Sumatra and Aceh, Indonesia and our findings are expected to be useful in developing mangrove conservation and restoration initiatives.
