Abstract

Nilem fish belongs to freshwater fish commodity that has been widely cultivation. Some factors influencing fish cultivation are good quality of feed, quantity, size, and shape. Quality feed works as a primary energy source as well as improves the digestive system of fish, with the expectation that the fish growth and health are optimal. Information concerning health status in cultivation Nilem has been used as a reference for improving cultivation methods and controlling disease attacks. The population and production of fish cultivation is experiencing serious problems due to infection from various types of pathogens. Therefore, a viable alternative is needed to prevent and overcome diseases by utilizing immunostimulant substances derived from synthetic substances that can increase the activity of non-specific immune defenses and stimulate antibiotic-forming organs in fish body. Immunostimulant is a substance that is capable of increasing the mechanism of non-specific immune response of fish one of them is by adding Chlorella vulgaris extract to the feed. This research objective is to determine the influence of Chlorella vulgaris supplementation on total blood albumin in nilem fish. This research was conducted by sampling method consisting of 5 treatments with further 4 replications. The treatments were feed supplementation of 0 g.kg-1, 2 g.kg-1, 3 g.kg-1, 4 g.kg-1, and 6 g.kg-1. Independent and dependent variables were used in this research; the independent variable was the dose of Chlorella vulgaris in the feed and the dependent variable was blood albumin concentration. The measuring of plasma albumin concentration was done using the Dyasis kit method with a spectrophotometer. The obtained data were then analyzed by ANOVA, followed by the Least Significant Difference (LSD) at the 95% confidence level if there is a real difference then followed by Tukey's test at the same confidence level. The results showed that the average value of serum albumin concentration of nilem fish from all treatments was between 4.2761 – 7.1826 g/dL. The normal albumin concentration was found in the treatment 4 g.kg-1 Chlorella vulgaris supplementation which was 4.77 g/dL. Meanwhile, the highest concentration was found from the supplementation of Chlorella vulgaris at 3 g.kg-1 feed which was 6.677 g/dL.

Abstract

Diopatra claparedii Grube, 1878, is a tubicolous polychaete species widely used as fishing bait by local anglers in Cilacap, Central Java, Indonesia. Little is known about its biological characteristics despite its ecological and economic importance. This study aimed to examine the survival rate, growth, metabolic rate, and osmoregulatory capacity of D. claparedii under different salinity conditions. The experiment was conducted using plastic containers (20 × 30 × 25 cm) filled with a muddy substrate and water at four salinity levels: 10, 15, 20, and 25 ppt, with each treatment replicated five times. The results showed that the survival rate of D. claparedii ranged from 87% to 93%, while its growth varied between 0.17 and 0.58 g. The metabolic rate, measured in terms of oxygen consumption, ranged from 0.201 to 0.467 mg·g-¹·h-¹. The  osmoregulatory capacity of the worms varied between 1.26 and 1.54 mOsm·kg-¹ solvent. Statistical analysis indicated that salinity did not significantly affect survival (p> 0.05). However, it significantly influenced growth, metabolic rate, and osmoregulatory capacity (p< 0.05). The results suggested that a 15–25 ppt salinity range was more favorable for the species, with 20 ppt being the most optimal level for its maintenance and growth. This study highlights the potential for cultivating D. claparedii under controlled conditions, providing a sustainable alternative to wild harvesting. As polychaete farming has been successfully implemented in several countries, similar efforts could be applied in Indonesia to support local fisheries while conserving natural populations.

Abstract

ABSTRACT. Cultivation of hard-lipped barb (Osteochilus vittatus) increased in the district of Banyumas, Indonesia. Supplementation Spirulina platensis and Chlorella vulgaris has lots utilized in field aquaculture as high nutritious food to increase fish production. Evaluation digestibility to S. platensis and C. vulgaris in hard-lipped barb fish can done with measurement composition body and activity enzyme digestion. The purpose of this study was to know the influence of supplementation of S. platensis and C. vulgaris and to find the most appropriate composition of supplementation to enhance body composition and digestive enzyme activity of hard-lipped barb. The study was conducted experimentally with completely randomized design (CRD) and consisting of five Treatments: P0 = without supplementation as control; P1 = S. platensis 6 g.kg-1; P2 = C. vulgaris 4 g.kg-1; P3 = ( S. platensis 3 g + C. vulgaris 2 g).kg-1; and P4 = ( S. platensis 2 g + C. vulgaris 3 g).kg-1, in four replicates. The results showed S. platensis and C. vulgaris increase hard-lipped barb protein, fat and fiber levels. C. vulgaris and combinations of S. platensis + C. vulgaris enhance activity trypsin-like, lipase, amylase, and alkaline phosphatase in foregut, hindgut, and hepatopancreas. C. vulgaris and S. platensis can be given as supplement of hard-lipped barb feed to enhance enzyme activity that contributing digestion​ to enhance body composition.

Abstract

Osphronemus gouramy is a potential Indonesian fish that needs to be supported by good nutritional feed and water quality in a culture system. The research on the effect of combining Chlorella vulgaris (C. vulgaris) supplementation with culture systems of biofloc and non-biofloc in gourami fish on amylase activity and blood urea level has not been conducted. Therefore, this study aims to determine the effect of C. vulgaris supplementation with different culture systems on the amylase activity of various digestive organs and blood urea levels. It obtains the best C. vulgaris supplementation feed combination to increase the amylase activity of various digestive organs and reduce blood urea levels. This research was carried out experimentally with a Factorial Completely Randomized Design consisting of two factors. Furthermore, gourami was fed with C. vulgaris levels of 0, 2, 3, 4, and 5 g kg-1 for 28 days and divided into biofloc and non-biofloc groups of culture systems. The amylase activity was measured at three pH buffers, and blood urea levels were analyzed using a urea kit. The results showed that amylase activity increased when supplemented with C. vulgaris 5 g kg-1 feed using the biofloc system, while blood urea levels decreased. C. vulgaris supplementation and biofloc system are alternative solutions to improving nutrition and water quality.

Abstract

Atherosclerosis is a cardiovascular disease characterized by the accumulation of oxidized lipoproteins in the arterial wall, which is triggered by LOX-1 receptor activation. The members of Syzygium genus contains secondary metabolites with antioxidant and anti-inflammatory activities that have the potential to inhibit LOX-1. This study aims to evaluate the interaction of compounds from Syzygium cumini, Syzygium aromaticum, Syzygium malaccense, and Syzygium jambos against LOX-1 using in silico method. Analysis was conducted through molecular docking, pharmacophore selection based on hydrophobic and hydrogen bond interaction criteria, and validation using Root Mean Square Deviation (RMSD ≤ 3 Å) values. The research results showed that gallic acid has the highest affinity (-4.1 kcal/mol), followed by linalool (-3.8 kcal/mol), kaempferol (-3.4 kcal/mol), oxalic acid (-3.4 kcal/mol), quercetin (-2.2 kcal/mol), and myricetin (-1.4 kcal/mol). The compounds with the highest affinity interacted with key LOX-1 residues, suggesting potential inhibition of the receptor. In conclusion, gallic acid is the most potent LOX-1 inhibitor candidate based on its stable interaction and highest affinity value. Further studies are needed to confirm its biological activity through in vitro and in vivo approaches.
