This study aims to analyze the feasibility of vannamei shrimp farming in Kramat District, Tegal Regency. The research was conducted on several shrimp ponds using semi-intensive and intensive systems. The analysis includes calculations of investment costs, fixed and variable costs, revenues, income, and business feasibility indicators such as R/C Ratio, Payback Period, Break Even Point (BEP), Net Present Value (NPV), and Internal Rate of Return (IRR). The results show that vannamei shrimp farming is feasible, as indicated by an average R/C Ratio of 1.68 and a Payback Period of 1.90. All ponds yielded positive NPV values, with an average of IDR 546,070,598 and an IRR of 58%, which exceeds the 5.5% discount rate. Both price and production BEP values have been surpassed in all farming units. The intensive pond system proved to be more profitable than the semi-intensive system. Therefore, vannamei shrimp farming in Kramat District, particularly in Dampyak Village, has strong financial prospects and is feasible for development through intensive approaches and the application of modern technology.

This study examines the effect of Environmental, Social, and Governance (ESG) ratings on firm performance and the moderating role of ESG rating disagreement within the Indonesian capital market. Using a panel dataset of 63 companies listed on the Indonesia Stock Exchange from 2021 to 2023 and employing a fixed-effects regression model, the analysis measures firm performance with Tobin’s Q, ESG ratings from Refinitiv Eikon, and ESG rating disagreement as the standard deviation between Refinitiv and Bloomberg scores. The empirical results indicate that ESG ratings do not have a statis-tically significant effect on firm performance, and ESG rating disagreement does not significantly moderate this relationship. These findings suggest that ESG-related information has not yet been fully internalized into firm valuation in Indonesia, with current ESG practices perceived as largely symbolic rather than substantively integrated into corporate strategy. The study concludes that both ESG ratings and rating disagreement fail to serve as effective mechanisms for enhancing firm performance in the Indonesian context, reflecting the early-stage development and compliance-driven nature of ESG adoption in emerging markets.

This study investigates the determinants of dividend payout policy in energy sector firms listed on the Indonesia Stock Exchange during the 2020–2024 period. Dividend policy is a critical issue in emerging markets, especially in capital-intensive industries with high investment needs and earnings volatility. The research examines whether profitability and ownership structure—specifically institutional and managerial ownership—significantly influence dividend payout decisions, considering firm characteristics. The study analyzes the effect of profitability, institutional ownership, and managerial ownership on the dividend payout ratio, while controlling for firm size and leverage. A quantitative approach is used, employing pooled ordinary least squares (OLS) regression on 245 firm-year observations. Dividend payout ratio is measured as dividend per share divided by earnings per share, profitability is proxied by return on equity, and ownership variables are expressed as shareholding proportions. Descriptive analysis and classical assumption tests precede hypothesis testing. The results show that profitability positively and significantly affects dividend payout, suggesting that firms with better financial performance tend to distribute higher dividends. Firm size also positively influences dividend policy, while leverage negatively impacts it, reflecting the role of financial capacity and capital structure. However, institutional and managerial ownership do not show significant effects on dividend payout decisions. The findings indicate that dividend policy in Indonesian energy firms is primarily driven by financial performance and structural characteristics rather than ownership-based governance mechanisms. This study offers sector-specific evidence that refines agency and signaling perspectives on dividend policy in emerging markets, with practical implications for managers, investors, and regulators.

This study aims to identify students' learning obstacles in the process of understanding one-variable linear equations in grade VII, develop an appropriate learning trajectory using a Realistic Mathematical Education (RME) approach, and produce an effective learning design to reduce these obstacles through generative models. The research adopts a design research methodology consisting of three main stages. The first stage, preparation for the experiment, includes a literature review and analysis of teachers’ instructional practices to develop a Hypothetical Learning Trajectory (HLT) for one-variable linear equations. The second stage, design experiment, involves testing the designed learning activities through a pilot experiment and teaching experiment. The third stage, retrospective analysis, compares actual classroom observations with the initial HLT to refine and validate the learning trajectory. The research subjects include seven grade VII students in the pilot experiment and 44 students from SMP Negeri 2 Mataram in the teaching experiment. Data collection methods include tests, observations, interviews, and documentation, with retrospective analysis used to generate a validated Local Learning Trajectory (LLT). The findings reveal several epistemological obstacles experienced by students, such as difficulties in applying fundamental arithmetic concepts (addition, subtraction, multiplication, division) within the context of linear equations. Students also struggled with concept recognition, representation, and interpretation of linear equations in various forms. The developed LLT proved effective, as students demonstrated improved understanding and were able to follow the learning sequence meaningfully. Retrospective analysis confirmed that the LLT successfully addressed and reduced students’ learning obstacles in mastering one-variable linear equations.

Wood consumption in Indonesia, which is expected to reach more than 64.84 million m³ by 2025, is putting enormous pressure on forests, as evidenced by the reduction in forest area through the clearing of 96,230 hectares of forest in 2023. To reduce dependence on wood as a building material, alternative materials with comparable physical and mechanical properties are needed. Bamboo, especially laminated bamboo, was chosen because it has high tensile strength, a short harvest time, and abundant availability. This study examines the behavior of hollow section laminated bamboo beam-column connections with a glue-in-rod-bracket system to determine the ductility of the connection under unidirectional (static) loads. An experimental method was used with the independent variables of diameter and number of bolts, while the dependent variables included the moment-rotation of the connection, stiffness, strength, and ductility. The results show that the average ductility values for 4 and 6 thread rods D6, D8, and D10 mostly meet the SNI 1729 (≥1.25) and AISC 360 (rotation >0.03 rad) standards, with classifications ranging from "partially ductile" to "fully elastic." However, the 10-diameter 6-thread rod only achieved a ductility of 1.2, thus failing to meet the SNI standard. Based on the Handbook of Structural Steel Connection Design and Details, all connections fall into the non-seismic category because their ductility values are less than 3. These findings confirm the potential of laminated bamboo as an environmentally friendly construction material, while also providing technical guidelines for the design of non-seismic beam-column connections.

Postpartum depression is a mood disorder that occurs in mothers after childbirth, with symptoms that can appear from pregnancy until 4 weeks postpartum. This condition negatively impacts the psychological health of the mother and the development of the baby. This study aims to analyze factors associated with the risk of postpartum depression. The method used was quantitative with an analytical survey design through a cross-sectional approach. Data collection was carried out using the Edinburgh Postnatal Depression Scale (EPDS) questionnaire consisting of 10 questions. The results of the validity test showed a calculated r value of > 0.3610 and the reliability test obtained a Cronbach's alpha value of 0.67. The study sample consisted of 42 respondents selected using a total sampling technique, with inclusion criteria of mothers aged ≥18 years, in the period <6 weeks postpartum, and willing to be respondents. Data analysis used the chi-square test. The results showed that all variables had a significant relationship with the risk of postpartum depression (p < 0.05). These variables include age (p=0.040), education (p=0.018), occupation (p=0.011), history of depression (p=0.024), complications (p=0.017), economic status (p=0.048), parity (p=0.016), type of delivery (p=0.006), husband's support (p=0.000), and family support (p=0.028). Therefore, it can be concluded that demographic, obstetric, and social support factors play an important role in the risk of postpartum depression. These results are expected to form the basis for prevention efforts and early intervention to improve postpartum maternal mental health.

This study aims to analyze the influence of customer experience and perceived value on tourist satisfaction among users of the Sidoarjo City Tour Bus as a form of public tourism transportation service. The Sidoarjo City Tour Bus represents a regional government service innovation intended to support tourism development while improving urban tourism accessibility. This study employs a quantitative approach using a survey method involving tourists who used the Sidoarjo City Tour Bus. Data were collected through questionnaires distributed to 99 respondents and analyzed using multiple linear regression with the assistance of SPSS software. The results indicate that customer experience does not have a significant effect on tourist satisfaction, suggesting that the experiences perceived by users are still subjective and not consistently felt by all service users. In contrast, perceived value has a positive and significant effect on tourist satisfaction, making it the most dominant variable in influencing satisfaction among Sidoarjo City Tour Bus users. These findings indicate that tourist satisfaction is more strongly determined by perceptions of benefits, service quality, and the suitability between sacrifices made and benefits received rather than by emotional experience alone. Therefore, this study recommends that the management of the Sidoarjo City Tour Bus and the local government enhance service value through improvements in facilities, information systems and registration processes, as well as optimization of comfort and schedule certainty. These efforts are important to increase tourist satisfaction and to support sustainable tourism development in Sidoarjo Regency.

This study aims to examine the effect of liquidity, company growth, and company size on firm value, with profitability as a mediating variable. These three independent variables are seen as internal factors that, theoretically, can influence firm value, both directly and indirectly through financial performance. This study employs a quantitative approach, using multiple linear regression analysis, path analysis, and Sobel tests to examine the mediation effect. The results show that liquidity has a significant effect on profitability, while growth and company size do not have a significant impact. Furthermore, the findings indicate that liquidity, growth, and company size do not directly affect firm value. However, profitability was found to significantly influence firm value and can mediate the relationship between liquidity and firm value. In contrast, profitability does not mediate the effect of growth or company size on firm value. These findings contribute to understanding the importance of profitability as a factor influencing firm value and provide insights into how internal company factors affect financial performance and firm value.
