The Indonesian government has been actively combating illegal fishing practices at sea because they harm the country and reduce fish populations. However, attention to freshwater fisheries, especially endemic fish, is still limited. In fact, endemic fish play an important role in aquatic ecosystems and local culture. Fish resource conservation aims to protect, preserve, and utilize fish and their ecosystems and genetic diversity so that their existence and availability remain sustainable. The diversity of freshwater fish in Indonesia faces serious threats from human activities. The main factor is the introduction of new species that grow uncontrollably, becoming pests and harming ecosystems and communities. In addition, overfishing and declining habitat quality further exacerbate the situation. These threats pose a risk of extinction for endemic fish. Therefore, conservation efforts need to be strengthened to maintain ecosystem balance and support the livelihoods of communities that depend on fish farming. Legal protection is an important aspect in addressing this issue. Law No. 31 of 2004 concerning Fisheries and Law No. 5 of 1990 concerning Conservation of Living Natural Resources and Ecosystems have provided a legal basis for fish resource management. However, their implementation and enforcement remain weak. This study uses a normative juridical approach with secondary legal materials, emphasizing the importance of improving the legal framework and more effective governance. Measurable, transparent, and sustainable conservation measures are needed to ensure the optimal utilization of fish resources. Thus, the sustainability of freshwater ecosystems and the welfare of communities that depend on endemic fish can be guaranteed.

The increasing demand for electrical energy and the issue of climate change are driving the utilization of renewable energy, one of which is through Solar Power Plants (PLTS). The Province of Bali targets the development of PLTS of 108.2 MW, equivalent to 8.62% of the total solar energy potential of 1,254 MW by 2025. However, land limitations pose an obstacle to the construction of large-scale PLTS. Floating solar power plant design can be a solution to this issue.

This study aims to analyze the effect of the Debt to Equity Ratio (DER) and Current Ratio (CR) on Return on Assets (ROA) at PT Sido Muncul Tbk for the period 2019–2023. The research employs a quantitative associative approach using secondary data obtained from the company’s annual financial reports. The analytical method applied is multiple linear regression with the assistance of SPSS version 26. Prior to hypothesis testing, the model was examined using classical assumption tests, including normality, multicollinearity, heteroscedasticity, and autocorrelation tests. The results show that DER has a positive and significant effect on ROA, indicating that a proportional increase in debt utilization can enhance company profitability. Similarly, CR has a positive and significant effect on ROA, implying that maintaining healthy liquidity strengthens asset efficiency. Simultaneously, DER and CR significantly influence ROA with a coefficient of determination (R²) of 0.887, meaning that 88.7% of profitability variation is explained by these two variables. These findings confirm that balancing capital structure and liquidity is a key determinant in improving financial performance within Indonesia’s pharmaceutical sector.

The rapid development of Artificial Intelligence (AI) has made it a part of the teens' routine, but the intensity of its use raises concerns about mental health. This study aims to analyze the pattern of AI utilization and its impact on stress, anxiety, and depression in students of St. Petrus Medan High School using the framework of Self-Determination Theory (SDT), namely competence, autonomy, and connectedness). The research was conducted with a quantitative approach through a survey of 64 students using a total sampling technique, equipped with focused group discussions (FGDs) and literature review. The results show that more than 70% of students use AI on a regular basis, mainly through chatbots (81%) and social media (73%). Some students (35.9%) also use AI as a means of venting. Although 85.9% of respondents found AI to be helpful, the majority (59.3%) reported feeling inferior as a result of comparing themselves to AI results. These findings reveal a psychological paradox, where AI is perceived as a solution as well as a source of pressure. This condition has the potential to trigger stress and anxiety, although depressive symptoms do not yet appear to be dominant. This research emphasizes the importance of healthy digital literacy as well as mentoring from schools and parents to reduce the risk of AI addiction and maintain adolescent mental well-being.

Pregnancy is frequently associated with discomforts such as back pain, edema, and postural changes that may interfere with daily activities. Approximately 50–70% of pregnant women experience back pain due to hormonal changes and increased body weight. The use of a Birth Ball is considered one of the non-pharmacological alternatives to alleviate these complaints, as it improves pelvic muscle flexibility and supports postural correction. Proper education is essential to ensure appropriate and effective utilization. This study aimed to evaluate the effectiveness of education using lecture and demonstration methods on the understanding of Birth Ball use among pregnant women. A pre-experimental design with a one-group pre-test post-test approach was applied. The sample consisted of 28 third-trimester pregnant women selected through purposive sampling. Findings revealed that the respondents’ understanding prior to education was 0%, which significantly increased to 96.43% following the intervention. Statistical analysis using the Wilcoxon Signed Rank Test yielded Z = -4.873 with p < 0.05, indicating a significant difference between pre- and post-education. It can be concluded that education delivered through lecture and demonstration methods is effective in enhancing pregnant women’s understanding of Birth Ball use.

This study aimed to examine the ecological and socio-economic aspects of mangrove utilization in Nasem Village, Merauke Regency, Papua Selatan. The ecological assessment included mangrove species composition, regeneration potential, health status, and Importance Value Index (INP).

This study examines the utilization of haiku as a form of response to postwar trauma through Kaneko Tota’s and Saito Sanki’s war-themed haiku. Following Japan’s defeat in World War II in 1945, a cultural shift occurred marked by transformation within traditional arts, particularly haiku, which became a significant medium for expressing traumatic historical and social experiences. Although both poets used haiku as a medium to express dissatisfaction and critique the socio-political conditions of the postwar period, they represented different generations and approaches in responding to postwar trauma. Saito, having directly experienced the trauma of war, developed a deconstructive strategy towards traditional haiku conventions. Meanwhile, Kaneko, belonging to the postwar generation, adopted a more radical approach in formal and semantic experimentation. These dual strategies not only embodied individual artistic responses to trauma but also contributed to a broader cultural project aimed at reconstructing Japan’s collective identity in the postwar era. Yuri Lotman’s cultural semiotics framework is employed to analyze the semiotic transformation dynamics in the poets' works. Lotman’s theory, with its key concepts of semiosphere, cultural text, and translation mechanisms, offers a comprehensive analytical tool for understanding the dynamics of sign systems and cultural meanings in World War II-themed haiku. From the analysis of five war-themed haiku, it is concluded that both poets constructed a collective trauma discourse. Rather than employing explicit descriptive narratives, the trauma discourse utilizes strong semiotic condensation strategies. Saito and Kaneko juxtaposed established cultural symbols and codes, such as Hiroshima as a metaphor of absolute destruction, the marathon as a symbol of life, breasts as a symbol of motherhood, and blooming flowers representing renewal into new surreal configurations that created novel meanings at the semiotic boundaries where tensions clashed.
