ya status gizi, asupan protein, dan aktivitas fisik. Oleh karena itu, penelitian ini bertujuan untuk mengetahui hubungan antara status gizi, asupan protein, dan aktivitas fisik dengan kadar hemoglobin pada calon pendonor di Unit Transfusi Darah (UTD) PMI Surabaya. Penelitian menggunakan metode observasional dengan desain cross-sectional yang melibatkan 170 calon pendonor yang dipilih melalui teknik consecutive sampling. Status gizi diukur berdasarkan Indeks Massa Tubuh (IMT) melalui pengukuran antropometri, asupan protein dinilai menggunakan kuesioner Semi-Quantitative Food Frequency Questionnaire (SQ-FFQ), aktivitas fisik diukur menggunakan International Physical Activity Questionnaire-Short Form (IPAQ-SF), sedangkan kadar hemoglobin diperoleh dari hasil pemeriksaan yang dilakukan oleh petugas PMI Surabaya. Analisis data dilakukan menggunakan uji korelasi Spearman. Hasil penelitian menunjukkan bahwa tidak terdapat hubungan yang signifikan antara status gizi dengan kadar hemoglobin (p=0,207) maupun antara asupan protein dengan kadar hemoglobin (p=0,196). Sebaliknya, aktivitas fisik memiliki hubungan yang signifikan dengan kadar hemoglobin (p=0,011) dengan arah hubungan positif dan kekuatan korelasi yang sangat lemah (r=0,195). Berdasarkan hasil tersebut, dapat disimpulkan bahwa aktivitas fisik berhubungan secara signifikan dengan kadar hemoglobin pada calon pendonor di UTD PMI Surabaya, sedangkan status gizi dan asupan protein tidak menunjukkan hubungan yang bermakna dengan kadar hemoglobin.

y on the competitiveness of salt farmers. A quantitative explanatory survey was conducted with 100 active salt farmers. The three constructs were measured using a five-point Likert-scale questionnaire and analyzed through multiple linear regression. Market access had a positive and statistically significant effect on competitiveness (p < 0.05), indicating that broader buyer networks, timely price information, alternative marketing channels, and stronger negotiating opportunities improve farmers’ ability to reach markets and sustain sales. Logistics efficiency also had a positive and significant effect (p < 0.05); reliable transportation, lower distribution costs, appropriate storage, proper handling, and shorter delivery times help preserve quality and reduce avoidable losses. The simultaneous test confirmed that both variables jointly affected competitiveness (p < 0.05). These findings indicate that increasing production alone is insufficient when farmers cannot reach profitable markets through efficient product flows. Collective marketing, transparent market information, shared storage, coordinated transportation, and direct relationships with processing industries are therefore essential for strengthening farmers’ bargaining power and market performance
Abstract:This study examines the effects of the Dow Jones Industrial Average (DJIA), world gold prices, world oil prices, and the rupiah exchange rate on the Composite Stock Price Index (CSPI) in Indonesia. The study uses monthly…
secondary data from January 2015 to December 2025, comprising 132 observations. CSPI data were obtained from the Indonesia Stock Exchange, DJIA, gold price, and oil price data were obtained from Investing.com, while exchange rate data were sourced from Bank Indonesia. The analysis employed the two-step Engle-Granger Error Correction Model (EG-ECM) to identify long-run relationships and short-run adjustment dynamics. The long-run results show that gold prices, world oil prices, and the DJIA have positive and significant effects on the CSPI, whereas the rupiah exchange rate has a negative but insignificant effect. In the short run, the exchange rate has a negative and significant effect on the CSPI, while gold prices, oil prices, and the DJIA have positive and significant effects. The Error Correction Term coefficient of -0.1325 is negative and significant, indicating that approximately 13.25% of short-run disequilibrium is corrected each month toward long-run equilibrium. These findings imply that investors and policymakers should closely monitor global market conditions, commodity price movements, and exchange rate volatility to support investment decisions and maintain Indonesian capital market stability

odic storytelling within brief viewing durations. Despite its increasing popularity, empirical research explaining the psychological mechanisms underlying Continuous Viewing Intention in short-form drama remains limited. This study investigates the influence of Viewing Motivation on Flow Experience and Continuous Viewing Intention. In this study, Viewing Motivation is conceptualized as a higher-order construct comprising Performance Expectancy, Social Influence, Hedonic Motivation, Habit, Substitute Expectancy, and Aesthetic Motivation. Data were collected through an online survey involving 140 respondents in Makassar who actively consume short-form drama content. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The findings indicate that Viewing Motivation significantly influences both Flow Experience and Continuous Viewing Intention. Furthermore, Flow Experience significantly affects Continuous Viewing Intention and mediates the relationship between Viewing Motivation and Continuous Viewing Intention. These findings underscore the importance of motivational drivers and immersive viewing experiences in fostering sustained engagement with short-form drama content

responsiveness of services at the stages of registration, administration, and consultation which have a direct impact on the perception of quality and satisfaction 2. Literature review shows a consistent pattern: long wait times decrease satisfaction, while short, predictable wait times increase satisfaction, especially in outpatient services that have higher expectations of timeliness 3. Waiting longer than 60 minutes is associated with a significant decrease in satisfaction scores, making the management of wait time duration and variability crucial. Determining factors include queue design, health worker capacity, administrative complexity, and timeliness of doctors; Meanwhile, digital solutions (e.g. Mobile JKN) speed up the pre-visit and visit process and related to a 5.6 reduction in waiting time. This review summarizes the findings of 2015–2024, maps the determinants and mechanisms of the relationship between wait time and satisfaction, and offers managerial strategies for healthcare facilities in Indonesia and internationally 7

s secondary data for the period 2015–2024. The analytical method employed is the Autoregressive Distributed Lag (ARDL) model to examine both short-run and long-run relationships, complemented by stationarity tests, cointegration tests, ECM estimation, and diagnostic and stability tests. The results show that international prices have a positive and significant effect on Indonesia’s clove export value, consistent with export-supply theory which states that higher global prices increase export incentives. The rupiah–rupee exchange rate displays a positive but insignificant relationship, indicating that exchange rate volatility is not sufficiently strong to influence changes in export value. Non-tariff measures, including SPS and TBT standards, are found to have a significant effect, reflecting the role of regulations in increasing compliance costs while simultaneously enhancing Indian consumer confidence in the quality of Indonesian cloves. India’s import volume also has a significant influence, showing that India’s domestic demand remains a major driver of Indonesia’s export value during the study period. This study is expected to provide insights for policymakers and industry players in strengthening trade strategies, particularly in enhancing the competitiveness of Indonesian clove exports through quality improvements, exchange rate stability, and compliance with non-tariff standards.

and the repayment rate of member loans. Data were processed using descriptive statistics and simple linear regression to assess the cooperative's financial balance and factors influencing business growth. The classical assumption test showed that the regression model met the feasibility criteria, both in terms of normality and autocorrelation, thus the analysis results were reliable. The t-test results proved that working capital had a positive and significant effect on cooperative business growth with a significance value <0.05. The coefficient of determination (R² = 0.887) confirmed that 88.7% of the variation in business growth was explained by working capital management. This means that the more optimal the management of working capital—including current assets, short-term liabilities, and member loans—the higher the cooperative's chances of growth and development. In addition to strengthening the existing literature, this study is consistent with the findings of Winata et al. (2023) on manufacturing companies and Herawati (2023) on savings and loan cooperatives, both demonstrated the importance of working capital management to financial performance. However, these results differ from the research of Rezki Erdian et al. (2022) on the retail sector, which found that receivables had no significant effect on profitability. This difference indicates that the relevance of working capital is highly dependent on the institutional context. Overall, this study confirms that optimal working capital management is not merely an administrative issue, but a strategic factor determining cooperative business growth and improving welfare. member.

stem that is not based on optimal demand calculations. This inefficiency causes wasteful costs and disrupts the smooth production process. The main objective of this study is to analyze current inventory management and apply the EOQ (Economic Order Quantity) method to determine the optimal order quantity, as well as evaluate its impact on cost efficiency and production operations. The EOQ method is expected to be a systematic and rational solution for managing inventory more efficiently. This study uses a descriptive quantitative approach. Data were collected through direct interviews with business owners and documentation of raw material purchasing and usage reports for 2024. The analysis was conducted using the EOQ formula to calculate the optimal order quantity, ordering costs, storage costs, safety stock, reorder point, and total inventory cost (TIC). The analysis results show that the optimal order quantity for teak wood raw materials is 282 boards, with an ordering frequency of 6 times a year. This number is more efficient than the actual ordering system which is carried out monthly without a fixed calculation. The recommended safety stock is 22 boards, with a Reorder Point (ROP) of 36 boards. The implementation of the EOQ method successfully reduced total inventory costs from Rp6,768,000 to Rp3,496,800.

mixed method. Primary data in this study were obtained directly from the Nias Tofu business through observations and interviews, while secondary data were obtained from the company in the form of production data from the Nias Tofu Product business in 2024. Data analysis was conducted using descriptive analysis techniques and the steps taken in the method analysis.MRP. According to the analysis results, the 2024 soybean raw material purchasing and demand data using the conventional method showed a shortage of raw materials of 14,200 kg with an order frequency of 14 times. Inventory management experienced inefficiencies, namely storage costs of IDR 1,600,000 and ordering costs of IDR 400,000, and raw material shortages still occurred, while the application of the MRP method resulted in order planning with an order frequency of 6 times, a fixed order quantity of 16,784 kg, and a much lower total inventory cost of IDR 335,160. The implementation of the MRP method has proven successful in eliminating raw material shortages and reducing operational costs so that the production process runs more smoothly and efficiently. This study proves that the application of MRP is effective in managing raw materials and optimizing production in the Nias Tofu business, making a significant contribution to smooth production and inventory cost efficiency.

tain long-term growth. This study evaluates Improvement and Scaling as the most suitable growth strategies, using a mixed-method approach that integrates semi-structured interviews and quantitative analysis through the Analytic Hierarchy Process (AHP) and financial assessment. In the short term, operational efficiency and service quality improvements are the main priorities, requiring investment in training and performance-based incentives. In the long term, branch expansion in Bandung is identified as the key growth initiative, with funding as the primary challenge since Bahagia Kopi still depends on internal capital. Financial analysis of 2023 reports shows increased profitability, but a 32% funding shortfall remains for expansion. To address this, Mixed Financing is the most balanced approach, maintaining a healthy solvency ratio while minimizing financial risk. With a cautious yet strategic approach, Bahagia Kopi can achieve sustainable expansion without overleveraging debt, ensuring long-term stability and maintaining business growth
