Abstract

Highlight ResearchThe most significant morphological variation was the snout length and caudal peduncleT. lepturus from the coast of Pati and Cirebon have a high morphometric character resemblance and possibly are members of the same populationT. lepturus in Demak waters formed a separate population group from T. lepturus from the coast of Pati and Cirebon, however still in the same species AbstractHairtails (Trichiurus spp.) are economically important fisheries resources and have become an export commodity. In Indonesia, there are several hairtail species; however, each species distribution is not yet certainly known. This study aimed to identify and determine the morphometric and meristic character of the hairtail from the northern coast of Java, Indonesia. Fish specimens were obtained from fishermen catches in the north coast of Pati and Demak (Central Java) and the northern coast Cirebon (West Java), which captures the fish in less than one-week fishing operation. Fish samples were grouped based on morphological similarities identified in previously published works. After that, 22 morphometric and four meristic characters were measured and counted. Principal Component Analysis and Discriminant Analysis were used to analyze morphometric data, while the meristic data were compared to the available published works. The hairtail caught at the northern coast of Java was long, flat, silvery in color, and had a sagittal crest, with the fin formula being D.III.125-134, P.I.10, and A.I.98-104. According to the morphological and meristic characters, the hairtail caught at Java's northern coast was identified as Trichiurus lepturus. The most significant morphological variation was the snout length and caudal peduncle. The PCA and scattergram analyses showed that T. lepturus from the coast of Pati and Cirebon have a high morphometric character resemblance and possibly are members of the same population.  T. lepturus in Demak waters formed a separate population group from T. lepturus from the coast of Pati and Cirebon, however still in the same species.

Abstract

Highlight ResearchWhite shrimp (Litopenaeus vannamei) challenged with IMNV and different stocking densitiesThe water quality parameter values are getting worse along with the increase in stocking densityWhite shrimp THC value decreased with increasing stocking density and IMNV challenge testThe development of the IMNV increased with an increase in stocking density seen from the speed and percentage of the appearance of the clinical symptoms and histopathology results AbstractIncreasing in stocking density of shrimp affects the physiology and behaviour of their moving space. The health condition of shrimp is influenced by feeding, growth, and its susceptibility on disease. The aim of this study was to determine the development of immune response in relation to density and the presence of IMNV infection. This study used a completely randomized design (CRD) at density of 100 shrimp.m-2, 200 shrimp.m-2, and 400 shrimp.m-2, with three replications in each treatment. The shrimp used was 5,02±0,26 g and the virus infection was exposed orally. This research was facilitated at the Disease Research Centre Laboratory of Central Proteina Prima Company, Pasar Kemis, Tangerang for 30 days. The results showed that the Total Hemocyte Count (THC) in hemolymph of shrimp had different values between negative controls and challenged IMNV. The lowest THC value was found at a density of 400 shrimp m-2 (3.00x106ml-1). While the highest THC value was at a density of 100 shrimp.m-2 (4.75x106ml-1). This result is supported by the increasing value of water quality parameters along with the increasing density of shrimp. Histopathology changes on skeletal muscle and lymphoid organs confirmed that the development of IMNV infection was faster at high shrimp densities.

Abstract

Highlight ResearchThe value of Leaf Area Index (LAI) and Normalized Different Vegetation Index (NDVI) have a strong relationship.Estimated mangrove leaf biomass and carbon stock in mangrove can be known through the Leaf Area Index (LAI) value.Each mangrove pixel can absorb the different carbon.Increasing the diameter of the tree trunk shows the more CO2 absorbed by the tree.AbstractWorldwide global warming occurs because of increasing carbon dioxide (CO2) in the atmosphere. Segara Anakan, the largest mangrove forest in Java Island, has the highest potential as a carbon sink in the tropics. This study aimed to quantify the area and density of mangrove forests in Segara Anakan and to estimate their potentials as carbon sink based on Sentinel-2A imagery. In this study, data from Sentinel 2A satellite imagery was processed and validated with field survey results. The results showed that Segara Anakan had mangrove forests covering an area of 5,481.64 ha in 2019 with the sparse density covered 706.92 ha, medium density covered of 2,526.80 ha, and high density covered 2,848.60 ha. The results of mangrove density were validated using Table Confusion Matrix and using correlation coefficient value (r) by comparing field measurement and Normalized Difference Vegetation Index (NDVI) algorithm. The accuracy for mangrove density was 86.92% with r-value 0.85. Mangrove in Segara Anakan has the ability to absorb 8.56 Mega gram of carbon per hectare. Segara Anakan mangroves have the potential to absorb high level of carbon, so we should maintain their sustainability.

Abstract

Highlight ResearchThe homogenization process affected the particle size reductionThe homogenization process using both High Speed Homogenizer and Ultrasound had a smaller particle size and the highest efficiency in encapsulation AbstractArthrospira platensis contains a high concentration of carotenoids mainly 80 % β-carotene. The use of β-carotene in functional food and nutritional supplements was constrained by its lack of chemical and physical stability. Therefore, efforts were needed to protect carotenoids from damage by using an encapsulation system. The emulsion preparation before the encapsulation process had an influence on the stability of the oil-in-water emulsion. Various methods were used to prepare emulsions, such as high shear homogenizers (HSH) and ultrasound (US) treatment. The homogenization step was critical because it influenced the chemical stability of any encapsulated compounds. The purpose of this work was to generate nanocapsules of β-carotene with minimum carotenoid degradation, high efficiency of encapsulation, and small particle size, with variation in the homogenization process. This study consisted of 5 treatments, including the homogenization processes used HSH 24.000 rpm for 90 s ; HSH 24.000 rpm for 60 s, amplitude 55 % for 120 s ; amplitude 94 % for 138 s ;  amplitude 55 % for 138 s ;  and  amplitude 55 % for 120 s . Each parameter was analysed by ANOVA followed by Tukey pairwise comparisons with 95% confidence level and p<0.05. The particle size was influenced by the emulsification process, such as homogenization treatment, homogenization time, amplitude, and time of sonication. The sample that was homogenized using both HSH and US had a smaller particle size and the highest efficiency in encapsulation than others. The combination of homogenization process could decrease particle size.
