Caridina boehmei is an ornamental shrimp native to Sulawesi that has been successfully cultured and marketed in Indonesia. However, molecular information about this shrimp is not yet available. This study aimed to characterize cytochrome c oxidase subunit I (CO1) and small subunit ribosomal RNA (18S rDNA) genes. Shrimp samples were extracted, and DNA was amplified using CO1 and 18S rDNA primers. The sequencing results were then analyzed by the neighbor-joining method. The 654 bp partial coding sequence (cds) of the CO1 and 380 bp partial cds of 18S rDNA have been successfully amplified from genomic DNA. The CO1 sequencing produced fragments consisting of 25.84% adenine, 20.95% cytosine, 19.11% guanine, and 34.10% thymine. The 18S rDNA sequencing produced fragments consisting of 24.47% adenine, 26.05% cytosine, 28.16% guanine, and 21.32% thymine. Phylogenetic analysis based on the CO1 gene revealed that C. boehmei was grouped with C. variabilis (MK190014), C. brachydactyla (MK190011), and Caridina sp. (MK190012). Phylogenetic analysis based on the 18S rDNA gene revealed that C. boehmei was identical to Caridina sp. Suphan Buri-1 MF622000, C. serratirostris KP725708, C. multidentata JF346236, C. formosae GQ131924, and Caridina sp. Suphan Buri-2 MF622001. The lowest-highest pairwise distance based on CO1 and 18S rDNA was consecutively 0.0017-0.2247 (0.17-22.47%) and 0.0000-0.1218 (0-12.18%).

This study analyzes the effect of liquidity, profitability, and company size on dividend policy in state-owned banks listed on the IDX for the period 2018-2024. The method used is multiple linear regression with panel data, processed using EViews, with a sample of four state-owned banks that meet purposive sampling. The results of the study indicate that liquidity and profitability have a positive and significant effect on dividend policy, while company size has a negative but insignificant effect. This finding indicates that banks with high liquidity and profitability are more likely to distribute larger dividends, while company size is not the main factor in dividend policy. This study provides implications for banking management to consider liquidity and profitability factors in determining dividend policy. In addition, investors are advised to pay more attention to profitability and liquidity as the main indicators in assessing a bank's dividend potential, rather than relying solely on company size.

Anguillid herpesvirus 1 (AngHV-1), a member of the Alloherpesviridae family, is known to cause high mortality in both wild and farmed eels. Notably, no cases of AngHV-1 infection in Indonesia until June 2023, when a significant mortality rate exceeding 75% among cultured glass eels was documented in Bogor, Indonesia. This study investigated the outbreak by collecting 30 diseased fish from multiple cultured tanks to examine clinical symptoms, histopathological changes, and viral presence through PCR targeting the viral DNA polymerase gene. Hemorrhagic lesions in the abdomen and anal regions were the primary clinical symptoms. Histopathological examination revealed hyperplasia, fusion, and epithelial lifting of the gill secondary lamellae. PCR, using 394 bp primer specific for AngHV-1, confirmed 100% infection among the collected samples, indicating rapid viral transmission within the rearing environment. Phylogenetic analysis of partial DNA polymerase amino acid sequences showed that Indonesian AngHV-1 isolate is genetically diverse and shares similarities with strains from China, Taiwan, Canada, and several European countries, suggesting the emergence of a novel strain. This study highlights the urgent need for enhanced biosecurity measures to curb AngHV-1 spread in the Indonesian eel aquaculture sector.

This review investigates the combined effect of neonatal hypothyroidism and low family income on the prevalence of intellectual disability, drawing insights from existing literature, including specific findings from studies involving neonatal cases such as 15 cases at Wangaya Regional Hospital Denpasar. Neonatal hypothyroidism significantly impacts cognitive development due to the critical role of thyroid hormones in brain maturation. Concurrently, low family income acts as a risk factor for intellectual disability by limiting access to essential healthcare, education, and developmental resources. The review explores the epidemiology of neonatal hypothyroidism, highlighting global and regional variations influenced by genetic, environmental, and socioeconomic factors. It delves into the mechanisms by which neonatal hypothyroidism affects brain and cognitive function, leading to deficits in intelligence, memory, attention, and executive function. Furthermore, the review examines the relationship between socioeconomic status and intellectual disability, emphasizing the role of resource scarcity and environmental factors associated with poverty. Findings from the reviewed literature suggest a compounding effect of neonatal hypothyroidism and low family income on a child's cognitive development and intellectual disability risk. Addressing this complex interplay necessitates a multifaceted approach, including early detection, prompt treatment, and integrated interventions spanning healthcare, education, and social support services. The review underscores the importance of equitable access to newborn screening, comprehensive early intervention programs, and family-centered support for children from low-income households.

The purpose of this study is to analyze the effect of liquidity ratio, leverage and profitability on financial distress before and after the Covid-19 pandemic, as well as to analyze the difference in liquidity, leverage and profitability on financial distress before and after Covid-19. This study uses data from retail companies listed on the Indonesia Stock Exchange (IDX) for the 2016-2023 period, where 2016-2019 is the pre-pandemic period and 2020-2023 is the post-pandemic period. Financial distress is measured using the springate method (s-score), for liquidity using the current ratio, leverage using the debt to equity ratio and profitability using return on assets. The results of the study show that liquidity has a significant effect on financial distress before the Covid-19 pandemic, but does not have a significant effect on financial distress after the Covid-19 pandemic. Leverage did not have a significant effect on financial distress before and after the Covid-19 pandemic. Profitability has a significant effect on the financial distress before and after the Covid-19 pandemic in the retail subsector listed on the IDX. Liquidity, leverage, and profitability simultaneously had a significant effect on financial distress before and after the Covid-19 pandemic in the retail subsector listed on the IDX. There was a significant difference between leverage against financial distress before and after the Covid-19 pandemic, but there was no significant difference between liquidity and profitability against financial distress before and after the Covid-19 pandemic in the retail subsector listed on the IDX.

This study focuses on the morphology of the Nile tilapia local strain (Salina), a salinity-tolerant tilapia hybrid strain developed by crossbreeding between female Nile tilapia Red NIFI with male Nile tilapia Sultana. The research aimed to analyse the morphometric characteristics of the Salina strain to understand species adaptation to suboptimal environmental conditions compared with the parental groups. A total of 60 Nile tilapia fish, ten female and ten male samples from each strain (Salina, Sultana, and red NIFI), were measured for their total length (TL), standard length (SL), head length (HL), body width (WID), dorsal fin length (DL), caudal fin length (CL), pectoral fin length (PL), caudal peduncle depth (CPD), eye diameter (ED), snout length (SNL), and body weight (BW). Each measurement parameter was then normalized by comparing it with the standard length (SL). The data were analysed using MS Excel 2019 and R v4.5.1 for all statistical analysis including MANOVA, Canonical Variance Analysis, Principal Component Analysis, and Hierarchical Clustering Analysis. Condition factor (K) and length-weight relationship (LWR) were calculated to investigate growth conditions and allometric growth patterns, respectively. Based on the findings, the six tilapia populations exhibit overlapping morphological traits, except for female Salina with slight differences in morphological variations. This implies its potential unique traits acquired from crossbreeding between two different strains. Meanwhile, male Salina showed morphometric traits closely aligned with its male parent, the Sultana strain. The condition factor across all populations indicates favourable growth conditions, although the negative allometric growth pattern suggests that length increases more rapidly than body weight, implying an adaptive trade-off in suboptimal environments.
