AbstractThe application of fertilizers in aquaculture ponds is one of the ways to increase water fertility which is characterized by an abundance of phytoplankton. However, further research on the effect of adding organic fertilizer to the abundance of plankton and the productivity of cultivation is necessary. This study aims to determine the effect of the use of liquid organic fertilizer and ceraclean on the abundance of plankton in the vannamei shrimp rearing media, and the survival and growth of vannamei shrimp. There were two treatments in this study, namely the application of ceraclean fertilizer 20 ppm/week in treatment 1 and the application of liquid organic fertilizer from chicken manure 20 ppm/week in treatment 2. Treatment 1 with addition of ceraclean fertilizer showed the highest abundance of plankton (262 Ind/l) compared with treatment 2 (225 Ind/l) (P < 0.05). However, the number of beneficial plankton identified in ponds with organic fertilizer application (treatment 1) was greater (80.0%) than ceraclean fertilizer application (treatment 2) (67.5%). This explained that organic fertilizer could significantly increase the growth and survival rate of shrimp by increasing the production of beneficially plankton which lead the lower of feed intake (FCR value of 1.1).

AbstractKoi fish is one of the ornamental fish that is in demand by ornamental fish lovers. Color quality is a determining factor for the economic value of koi fish production. The purpose of this study was to determine the effect of adding squid ink supplements to feed on increasing black color and growth in koi fish. This study used a completely randomized design with 4 different doses of treatment with 3 replications. Treatment P0 without the addition of squid ink (control), P1 was 1% squid ink, P2 was 3% squid ink and P3 was 5% squid ink in the feed. Koi fish are kept in an aquarium with feeding rate of 5%. The main parameters observed were increasing black color and absolute growth of koi fish. The black color assessment was observed using a modified Toca Color Finder. Supporting parameters were water quality. The results showed that 5% squid ink treatment resulted in the highest black color score. The absolute weight growth between treatments showed a significant difference (p<0.05) and the absolute length growth did not show a significant difference (p>0.05). It can be concluded that the addition of squid ink with a concentration of 5% is the best treatment.

Abstract
This study’s purpose is to know the condition of corals in locations that are under pressure due to high sedimentation and coral damage due to ship aground. The research was carried out in August 2021 by collecting data related to the coral reef’s condition. The method used the Underwater Photo Transect (UPT) at 2 location points as controls which were assumed not to be affected by the ship aground and 2 location points where the ship ran aground. The study was successful to obtain data on the affected corals on the BG Financia 22 ship at 13.13%, while at the control location, live coral cover was obtained by 17.16%, grouped in very damaged condition. Observations on the BG Intan Kelana 3 ship from a total observation area of 127,600 cm2, obtained a live coral cover of 24.70%, this condition is grouped in very damaged coral conditions. Types of coral were found in 17 genera from 247 colonies observed during the study. Coverage at affected locations is 4.20%. Observations in this study can be concluded at the location where the condition of the coral is very damaged plus the pressure due to the ship aground, thus worsening conditions in the area.

AbstractScalloped spiny lobster (Panulirus homarus) is a commodity due to its high economic value, and it increases the exploitation of lobster. This increase needs to be balanced with good cultivation, which one is feed. Currently, the main feed given by the cultivators still depend on trash fish. The purpose of this study was to increase formulated diets with different protein on feed consumption, feed conversion ratio, feed efficiency and nutrient retention. This study was conducted using Completely Randomized Design with 5 treatments and 4 replications, namely P0 : trash fish (control), P1 : protein feed 30 %, P2 : protein feed 40 %, P3 : protein feed 50 %, and P4 : protein feed 60 %. Lobster rearing is carried out for 30 days at the Faculty of Fisheries and Marine Airlangga University. Analysis of research data used Analysis of Variance (ANOVA) and continued with Duncan’s Multiple Range Test with a level of 5% to determine the best results. The result showed that potency of formulated diets with different protein had a significant effect (p< 0,05) on feed consumption and nutrient retention, but had no significant effect (p> 0,05) on feed convertion ratio and feed efficiency.

Abstract
Tilapia lake virus disease is an emerging viral disease causing mortality up to 90% worldwide of aquaculture production. It has been recorded as a virus attacting wild and cultured tilapias in Asia, Africa, and Latin America. There is the urgent need for rapid Diagnostic techniques for viral diseases to identify infected tilapia to control the outspread in individual farms. This study aims to identify the presence of TiLV with the semi-nested Reverse Transcriptase-Polymerase Chain Reaction method allowing the rapid detection of TiLV in fish organs. A total of 4 samples of tilapia were isolated from different locations and then used a silica extraction kit to obtain RNA from the TiLV virus. Afterwards amplification step was carried out by semi-nested RT-PCR test. The primers used in PCR target the 250-bp fragment in the electrophoresis. The results showed that the 250 bp amplicon of TiLV RNA was detected at 1/4 tested Tilapia. PCR clearly identified infective TiLV viral RNA in tilapia that produced a cytopathic effect with protein similarity (weak homology) in the conserved Polymerase Sub Unit PB1 Influenza-C and the genome of Orthomyxoviruses causing brain, nervous system and liver damage in fish and may have applications as rapid species-specific virulence test.

Published: December 2023

Abstract
Kenjeran Beach is located in the coastal area of the East Coast of Surabaya (Pamurbaya) where most of the ecosystems are mangroves, so this area has the potential to be inundated with water (flood). This study aims to analyze tidal flooding as the impact of sea level rise and formulate appropriate adaptation & mitigation strategies so that tourism utilization can be carried out in a sustainable manner. The method used in this study was the tidal calculation which produces sea level rise predictions and the Geographic Information System method which produces a map of the vulnerability of the tidal flood area. The map results were analyzed to determine adaptation and mitigation strategies from the tidal flood. Based on the analysis of sea level rise, the area inundated due to tidal flooding was around 42 cm in the next 50 years. In an effort to adapt and mitigate sea level rise disasters, it was carried out with structural (physical or technical) mitigation and non-structural (non-technical) mitigation.

Abstract
This study aims to determine the effectiveness of commercial feed with probioticand vitamin C supplements in repairing damage to the gill structure of freshwater fish, tilapia (Oreochromis niloticus). Tilapia in this study were divided into control group (commercial feed), probiotic group (commercial feed with probiotic 200 mg/kg of feed), and vitamin C group (commercial feed with vitamin C 100 mg/kg of feed). Each group was givenmicroplastic particles exposure treatment in aqueous media (0, 0.1, 1, 10 mg/L volume of aquarium water) which was carried out twice a day for 14 days. The results showed that the administration of vitamin C as fish feed supplement reduced the damage that occurred in the tilapia gills in the form of edema (22 ± 3.57%), necrosis (33 ± 4.07%), hyperplasia (38 ± 5.91%), epithelial lifting (28 ± 3.43%), and fusion (17 ± 3.49%) of the secondary lamellae. Meanwhile, the administration of probiotics only reduced the histopathological conditions of necrosis (34 ± 4.57%) and fusion (18 ± 3.07%) of secondary lamellae. From all treatments, it was shown that feeding with vitamin C was the most effective in improving the histopathological condition that occurred in the histological structure of tilapia gills.

Abstract
Lake Singkarak has endemic fish resources of only one species in the world that has economic value, namely Bilih (Mystacoleucus padangensis, Blkr.). The rapid rate of catching using dipp nets fishing gear in this lake is expected to result in a decline in the Bilih population. Dipp nets is a fishing gear that is not environmentally friendly. Bilih fish samples were obtained using dipp nets fishing gear at two locations, namely Intake PLTA (hydropower intake) and Batu Taba for seven (7) months from June to December 2021. The number and size distribution of Bilih were calculated spatially and temporally. The abundance of fish in the Intake PLTA and Batu Taba locations were 472 fish and 716 fish, respectively. As spatially the size range of fish in Intake PLTA is 45-104 mm and in Batu Taba 40-130 mm. The highest fish size is in the 65-72 mm class range, both spatially and temporally (June). Average water quality at Intake PLTA location (temperature 27.87 °C; pH 8.6; DO 4.68 mg/L; Conductivity 0.143 mS/cm; TDS 0.092 mg/L) at a depth of 14.15 m and at Batu Taba location (temperature 28.14 °C, pH 9.24; DO 4.68 mg/L; Conductivity 0.231 mS/cm; TDS 0.092 mg/L) at a depth of 14.15 m.

Published: December 2023

Abstract
Due to the limitations of tendon biology, high-quality tendon repair remains a clinical and scientific challenge. Here, a micro–nano hierarchical scaffold is developed to promote orderly tendon regeneration by providing temporal-matched biological constraints. In short, fibrin (Fb), which provides biological constraints, is loaded into poly (DL-lactide-co-glycolide) nanoyarns with suitable degradation cycles (Fb-loaded nanofiber yarns (Fb-NY)). Then further combined with braiding technology, temporary chemotactic Fb scaffolds with tendon extracellular matrix-like structures are obtained to initiate the regeneration process. At the early stage of healing (2 w), the regeneration microenvironment is regulated (inducing M2 macrophages and restoring the early blood supply necessary for healing) by Fb, and the alignment of cells and collagen is induced by nanoyarn. At the late healing stage (8 w), with the degradation of Fb-NY, non-functional vascular regression occurs, and the newborn tissues gradually undergo load-bearing remodeling, restoring the anvascularous and ordered structure of the tendon. In summary, the proposed repair strategy provides temporal-matched biological constraints, offering a potential pathway to reconstruct the ordered structure and function of tendons.

Published: December 2023

Abstract
Metal additive manufacturing (AM) has been extensively studied in recent decades. Despite the significant progress achieved in manufacturing complex shapes and structures, challenges such as severe cracking when using existing alloys for laser powder bed fusion (L-PBF) AM have persisted. These challenges arise because commercial alloys are primarily designed for conventional casting or forging processes, overlooking the fast cooling rates, steep temperature gradients and multiple thermal cycles of L-PBF. To address this, there is an urgent need to develop novel alloys specifically tailored for L-PBF technologies. This review provides a comprehensive summary of the strategies employed in alloy design for L-PBF. It aims to guide future research on designing novel alloys dedicated to L-PBF instead of adapting existing alloys. The review begins by discussing the features of the L-PBF processes, focusing on rapid solidification and intrinsic heat treatment. Next, the printability of the four main existing alloys (Fe-, Ni-, Al- and Ti-based alloys) is critically assessed, with a comparison of their conventional weldability. It was found that the weldability criteria are not always applicable in estimating printability. Furthermore, the review presents recent advances in alloy development and associated strategies, categorizing them into crack mitigation-oriented, microstructure manipulation-oriented and machine learning-assisted approaches. Lastly, an outlook and suggestions are given to highlight the issues that need to be addressed in future work.
Synthetic pre-training for neural-network interatomic potentials
Authors: Gardner John L A , Baker Kathryn T , Deringer Volker L 
Published: December 2023

AbstractMachine learning (ML) based interatomic potentials have transformed the field of atomistic materials modelling. However, ML potentials depend critically on the quality and quantity of quantum-mechanical reference data with which they are trained, and therefore developing datasets and training pipelines is becoming an increasingly central challenge. Leveraging the idea of ‘synthetic’ (artificial) data that is common in other areas of ML research, we here show that synthetic atomistic data, themselves obtained at scale with an existing ML potential, constitute a useful pre-training task for neural-network (NN) interatomic potential models. Once pre-trained with a large synthetic dataset, these models can be fine-tuned on a much smaller, quantum-mechanical one, improving numerical accuracy and stability in computational practice. We demonstrate feasibility for a series of equivariant graph-NN potentials for carbon, and we carry out initial experiments to test the limits of the approach.

Published: December 2023

Abstract

Objective
The Test of Practical Judgment (TOP-J) is a stand-alone judgment measure that is considered to tap into aspects of executive functioning (EF) and inform clinical predictions of daily functioning in older adults. Past validation research is variable and has some limitations. The present study sought to examine the reliability and construct, criterion, and incremental validities of scores on TOP-J 9-item version (TOP-J/9).

Method
Participants were 95 community-dwelling older adults aged 60 to 85. Participants completed TOP-J/9, measures of EF and global cognition, and three different modalities of instrumental activities of daily living (IADLs) (self-report, performance-based tasks conducted in the laboratory, and performance-based tasks completed at home over 3 weeks).

Results
TOP-J/9 scores showed adequate internal consistency (α = 0.73) after correcting for the low number of items. TOP-J/9 was correlated with global cognition and EF, although EF did not survive correction for lower-order processes. Finally, although TOP-J/9 scores were associated with home-based IADL tasks (but not with self-report and laboratory-based IADLs), providing some evidence of criterion validity, they did not incrementally contribute to home-based IADL performance beyond other cognitive measures. However, when two items pertaining to social/ethical judgment were removed, this modified version of TOP-J did relate to EF beyond lower-order processes and contributed uniquely to prediction of home-based IADLs beyond other measures.

Conclusion
Results suggest that TOP-J/9 taps into global cognitive status (but not necessarily EF) and predicts “real-world” functioning (but not above and beyond other cognitive measures). TOP-J psychometrics may be improved by removing two social/ethical items.

Abstract
The sense of smell is based on sensory detection of the molecule(s), which is then further perceptually interpreted. A possible measure of olfactory perception is an odor-independent olfactory perceptual fingerprint (OPF) defined by Snitz et al. We aimed to investigate whether OPF can distinguish patients with olfactory dysfunction (OD) due to coronavirus disease (COVID-19) from controls and which perceptual descriptors are important for that separation. Our study included 99 healthy controls and 41 patients. They rated 10 odors using 8 descriptors such as “pleasant,” “intense,” “familiar,” “warm,” “cold,” “irritating,” “edible,” and “disgusting.” An unsupervised machine learning method, hierarchical cluster analysis, showed that OPF can distinguish patients from controls with an accuracy of 83%, a sensitivity of 51%, and a specificity of 96%. Furthermore, a supervised machine learning method, random forest classifier, showed that OPF can distinguish patients and controls in the testing dataset with an accuracy of 86%, a sensitivity of 64%, and a specificity of 96%. Principal component analysis and random forest classifier showed that familiarity and intensity were the key qualities to explain the variance of the data. In conclusion, people with COVID-19-related OD have a fundamentally different olfactory perception.
Tracking reproductive events: Hoof growth and steroid hormone concentrations in hair and hoof tissues in moose (Alces alces)

Published: December 2023

Abstract
Measurements of reproductive and stress-related hormones in keratinous tissues (e.g. hair, claws, hooves, baleen) can provide a record of stress and reproductive response in wildlife. We evaluated a method to collect keratin tissue from hooves of immobilized moose (Alces alces) and validated enzyme immunoassays for measuring cortisol and progesterone in hooves and hair. We also measured the annual growth and wear rates of moose hooves. Progesterone (range: 1.0–43.7 pg/mg) and cortisol (range: 0.05–2.9 pg/mg) were measurable and showed variation among hoof samples and moose. Pregnant females had twice as high progesterone concentrations (18.00 ± 3.73 pg/mg) from hoof sample locations post breeding compared to non-pregnant moose (9.40 ± 0.25 pg/mg). Annual hoof growth differed between the front (5.58 ± 0.12 cm) and rear (4.73 ± 0.13 cm) hooves and varied by season with higher growth rates during summer which decreased into autumn and winter. Adult female hooves represented between 1.6 and 2.1 years of growth and included up to two reproductive cycles. We established a method to estimate hoof growth rate and applied this to postmortem samples and were able to detect previous pregnancies. Shoulder guard hairs grew between August and March including during late gestation; however, hair progesterone concentrations (range: 2–107.1 pg/mg) were not related to reproductive state. Hair cortisol concentrations in our study (range: 0.2–15.9 pg/mg) were within the range of values previously reported for cervids. Our study supports the use of hooves for longitudinal sampling and measuring reproductive and stress-related hormones, providing a new tool for tracking reproductive events and understanding what variables may contribute to population level changes in reproduction.
