Abstract

The use of pineapple fruit extract as an immunostimulant in aquaculture has become the focus of significant research in efforts to improve the immune systems of aquatic organisms, especially farmed fish. Pineapple fruit extract, which contains bromelain, has attracted attention as a potential natural solution to improve the immune response of fish against pathogens and disease. The main aim of this review is to evaluate the extent to which the use of pineapple as an immunostimulant is effective in improving the immune system of fish or other aquatic organisms in an aquaculture context. This article uses literature study methods from several national, accredited national journals and reputable international journals. Literature study is the process of searching, collecting and analyzing various sources of information relevant to a particular topic. Pineapple extract contains bromelain, which has immunomodulatory and anti-inflammatory properties. It can improve the fish's immune response and reduce inflammation, helping to improve fish health. The use of pineapple fruit extract can reduce dependence on antibiotics in the treatment of sick fish, which is in line with global efforts to overcome antibiotic resistance and environmental impacts. With the right efforts, the use of pineapple fruit extract as an immunostimulant in aquaculture has the potential to increase the productivity and sustainability of the aquaculture industry, as well as reduce dependence on antibiotics and synthetic chemicals. Therefore, further research and development of best practices in the use of pineapple fruit extract in aquaculture are necessary steps to realize its potential as a more environmentally friendly and sustainable alternative.

Abstract

Facial nerve paralysis is a common event in cases of cranial base trauma. Especially facial nerve paralysis due to trauma or fracture of the temporal bone accounts for around 7-10% of cases. Analysis of studies related to the management of facial nerve paralysis due to skull base fractures still needs to be studied. The aim of this paper is to examine in more depth the management of facial nerve paralysis due to traumatic skull base fractures. This research analyzes studies through the PubMed, Google Scholar, and Proquest databases. After searching, 729 articles were found. Seven articles were found that were suitable and discussed the management of facial nerve paralysis due to cranial base trauma. Based on the results of the investigation, it was found that the management carried out was based on the severity scale of facial paralysis where medical or surgical treatment could be carried out according to the required indications.

Abstract

Long beans (Vigna sinensis L.) have the potential to be developed because they have high economic value. However, this is not supported by a decrease in production availability for 5 years. One of the efforts made is to improve fertilization and pruning techniques. The aim of this research is to determine the interaction of bocation and pruning on long bean production. This research used a Randomized Block Design with a factorial pattern of 2 factors with 3 levels of treatment, namely: Factor I = Bokasi (B) consisting of B0 = No Bokasi (control), B1 = Bokasi solid cow dung 10 tons /haB2 = Bokasi dung solid pigs 10 tons/ha and B3 = liquid bokasi with a concentration of 1400 cc liters of water-1 plot-1 and Factor II = pruning (P) which consists of P0 = no pruning, P1 = pruning 21 HST and P2 = pruning 35 HST. The research results found that there was an interaction between giving bokasahi fertilizer (1,400 cc plot-1) and pruning time (21 HST) which had a very real influence and gave the best results on the research variables.

Abstract

Stelechocarpus burahol (kepel) belongs to the Annonaceae family, and is considered to be a native species to Indonesia which is mainly distributed on the island of Java. However, the plant’s existence is currently difficult to find, so it is categorized as rare in Indonesia. A molecular approach using DNA barcoding technique is significant to assist plant identification. The gene that is widely used and proven to be accurate for Annonaceae is trnL-F. This study was aimed to evaluate the efficiency of trnL as DNA barcode for the identification of S. burahol and its relatives (Annonaceae) from Java Island. In total 10 specimens have been used in this study. Whole genome DNA was isolated by Tiangen kit and amplified by Polymerase Chain Reaction (PCR) technique using a specific primer. Results showed that trnL was easily amplified with a DNA fragment length of 500-600 bp. The trnL amplicons have successfully sequenced as indicated by the high QV20+ values. The sequence compositions were high in AT bases (63.9%). BLAST analysis of the sequences showed that S. burahol and sister species have been confirmed its identity according to the reference sequences in NCBI with query cover identities 98%-100%. This research can be concluded that trnL-F is suitable and recommended as a DNA barcode for S. burahol and its relatives. However, further research is suggested to combine analysis of both coding (rbcL, matK, etc) and non-coding (trnL) markers for better identification results.

Abstract

Several Odonata studies on Lombok Island still focus on forest and river habitat types. This causes the diversity of this insect group to be unknown in other habitats such as rice fields. This research aims to explore the richness of dragonfly species in the rice field ecosystem of Perian village, Montong Gading subdistrict, East Lombok district. Sample collection was carried out in May – June 2022. Dragonfly searches were carried out in the morning from 08.00 – 12.00, and in the afternoon from 14.00 – 18.00 on two transects determined purposively. The odonata found were documented using a digital camera, and captured using insect nets. Samples that were successfully collected were identified to the species taxon. The total odonata we found were 2 suborders, 5 families and 11 species. The suborder Zygoptera is the group with the highest species richness. For families, Libellulidae and Coenagrionida are the families with the highest species richness compared to other families. Of the 11 species that we found, 1 species is endemic, namely Euphaea lara lombokensis. Compared with the results of previous research conducted in Suranadi and Batu Bolong River, there are 5 species which are new records. The five species are Copera ciliata, Rhinocypha bisignata, Ischnura senegalensis, Ischnura heterosticta, and Brachythemis contaminata. The results of this study indicate that there are more species from the Odonata order on Lombok Island compared to previous reports.

Abstract

The success of artificial insemination in chickens is very dependent on sperm quality. Sperm temperature and diluent during storage can affect sperm quality. This study evaluated the quality of Bangkok chicken sperm diluted with 5% glucose and NaCl stored at 5 ⁰C and 26 ⁰C. The research design used was completely randomized. The data obtained were analyzed using a variance. The results showed that the motility of sperm preserved for 9 hours at 26 ⁰C with infused NaCl and Glucose 5% differed significantly (P< 0.05) with motility of 50±0.0% and 34±8.94%, respectively. While preservation under 5 ⁰C for 9 hours with NaCl, better than Glucose 5% (P<0.05) with motility of 58.00±10.95% and 38.00±10.95%, respectively. The viability of sperm preserved at 26 ⁰C with glucose 5% extender was better than NaCl (P<0.05) with a value of 58.93±1.27% and 33.43±1.27%, respectively. While preservation at 5 ⁰C of viabilities of sperm under Glucose 10% and NaCl were not significantly different (P>0.05) from values of 52.57±5.15% and 48.14±8.09%, respectively. The abnormality of sperm stored at 26 ⁰C and 5 ⁰C for 9 hours with NaCl and Glucose 5% were not different (P>0.05). Insemination using 100 million sperm with infused NaCl extender from 18 eggs produced 94.44% (n=17) fertility and 72.22% (n=13) hatchability. While insemination using infuse glucose 5% extender, 11 eggs produced 63.64% (n=7) fertility and 54.54% (n=6) hatchability. The infusing NaCl extender produced better sperm quality, fertility, and hatchability than glucose 5% at 5 ⁰C.

Abstract

Neutrophils, also known as polymorphonuclear leukocytes, play a significant role in fueling systemic inflammation and tissue damage within the context of frailty, a clinical syndrome associated with increased susceptibility to stressors and decreased functional performance typically linked to aging. This literature review delves into the interplay between neutrophils and frailty, shedding light on their contribution to age-related systemic inflammation. The investigation explored the correlation between heightened neutrophil levels, diminished physical activity, increased frailty, and elevated white blood cell counts. These findings underscore the substantial role of neutrophils in the development of frailty, necessitating further research to enhance comprehension of their involvement for more effective prevention and intervention strategies. The implications of this study emphasize the importance of tailored exercise regimens, promoting optimal nutrition practices, efficiently managing chronic inflammation, and improving the control of chronic diseases as essential approaches to address frailty among older individuals.

Abstract

Gastropods are one of the classes of mollusks that associate well with seagrass ecosystems. The waters of Pasir Putih are included in a coastal area where many types of gastropods are found in seagrass ecosystems. However, not all types of gastropods in seagrass beds in this region are well known. For this reason, this study aims to determine the types of gastropods associated with seagrass ecosystems in the waters of Pasir Putih, Manokwari. But specifically the objectives of this study are divided into 3, knowing the types of gastropods, seagrass species and the association of gastropods with seagrass in Pasir Putih Waters, Manokwari. In sampling, the quadratic transect method was used, drawn perpendicularly from the shore towards the shore. Physical parameters of water chemistry were observed in situ, this data collection method used was descriptive method. Based on the results of the identification that has been done, that there are 115 individuals, 42 species and 15 families that exist in the White Sand Waters, Manokwari. Four seagrass species were found, namely Cymodocea rotundata, Halodule pinifolia, Halophila ovalis, and Syringodium isoetifolium.
