Diabetes mellitus is a chronic disease that requires long-term pharmacological therapy, increasing the risk of Drug Related Problems (DRPs). DRPs can affect the success of therapy, increase the risk of complications, and reduce the patient's quality of life. This article aims to identify the use of antidiabetic drugs, the characteristics of DRPs, and their clinical implications. The method used was a literature review of articles from 2016-2026 that are relevant to the analysis of DRPs in diabetes mellitus patients. The results of the study indicate that metformin is the most widely used antidiabetic drug, both as a single therapy and in combination. The dominant types of DRPs include drug interactions, inappropriate drug selection, inappropriate dosages, omissions from therapy, and use of drugs without indications. These DRPs can cause hypoglycemia, failure to achieve glycemic control targets, an increased risk of complications, and increased duration and cost of treatment. Based on the results of the study, it is concluded that DRPs remain a challenge in the management of diabetes mellitus therapy, requiring more optimal monitoring and an active role of pharmacists through medication review to improve the safety, effectiveness, and quality of treatment.

This study aims to analyze the implementation of efficiency, effectiveness, and consistency in the Standard Operating Procedure for goods procurement in the purchasing department of The Oberoi Beach Resort, Bali. This research employed a descriptive qualitative approach, with data collected through semi-structured interviews, observation, and documentation. The informants included parties directly involved in procurement activities, namely the Purchasing Manager, Purchasing Supervisor, Purchasing Staff, Receiving Staff, and user departments. Data were analyzed through data reduction, data display, and conclusion drawing and verification. The findings show that the goods procurement SOP has been implemented in a structured manner through Purchase Requisition submission, document approval, Purchase Order issuance, supplier ordering, and goods inspection by the receiving department. The SOP is effective in supporting hotel operational needs and relatively consistent because control stages are maintained even under urgent requests. However, efficiency has not been fully optimized because administrative and approval processes still rely on a manual paper-based system. Other barriers include inventory data input errors, supplier stock limitations, customs constraints, and weather-related distribution disruptions. This study recommends the implementation of e-procurement, stronger interdepartmental coordination, improved inventory data accuracy, and supplier diversification.

This study aims to analyze the effect of capital structure, asset growth, and firm size on firm value in plastic and packaging sub-sector companies listed on the Indonesia Stock Exchange during the 2020–2024 period. Firm value is proxied by Price to Book Value (PBV), capital structure is measured using the Debt to Equity Ratio (DER), asset growth is measured by the asset growth ratio, and firm size is measured using the natural logarithm of total assets. This research employed an explanatory quantitative approach using secondary data obtained from financial statements, annual reports, and stock price data. The sample consisted of 11 companies observed over five years, resulting in 55 panel data observations. Data were analyzed using panel data regression through the Common Effect Model, Fixed Effect Model, and Random Effect Model, with model selection based on the Chow, Hausman, and Lagrange Multiplier tests. The results indicate that capital structure, asset growth, and firm size have no significant effect on firm value, either partially or simultaneously. These findings suggest that firm value in the plastic and packaging sub-sector is not sufficiently explained by financing structure, asset expansion, or company size. Investors are more likely to consider other factors, such as profitability, operational efficiency, cash flow, sales growth, raw material risk, and sustainability prospects. Therefore, companies should improve financial performance, asset efficiency, cost control, and sustainable innovation to enhance firm value.

Lake Rawa Pening is one of Indonesia’s priority lakes facing serious ecological pressure due to the rapid proliferation of water hyacinth. This study aims to classify and map the distribution of water hyacinth in Rawa Pening Lake during the 2021–2025 period and to analyze the seasonal distribution patterns of water hyacinth. Sentinel-2 imagery processed on the Google Earth Engine platform was classified using the Random Forest algorithm combined with hybrid sampling and spectral indices (NDVI, NDWI, MNDWI, and SRI). Classification accuracy assessment showed high performance with an Overall Accuracy of 97.45% and a Kappa coefficient of 0.949. The results indicate significant spatial-temporal fluctuations, with the highest coverage recorded in March–April 2021 (855.75 ha) and the lowest in May–June 2022 (108.44 ha). Seasonal-Trend Decomposition using Loess (STL) revealed consistent seasonal patterns, with peak expansion occurring during the rainy season, particularly in January–February. Although initial implementation of lake management policies reduced coverage, subsequent increases suggest that control measures remain insufficiently sustainable. This study demonstrates the effectiveness of cloud-based satellite monitoring for evaluating lake management policies and supporting evidence-based environmental management strategies.

Heat stress is a major constraint in broiler production systems located in humid tropical climates, where high ambient temperature and relative humidity impair growth performance, feed efficiency, and animal welfare. This systematic review synthesizes peer-reviewed studies published between January 2015 and December 2025 evaluating environmental housing designs and cooling strategies for mitigating heat stress in broiler chickens. This systematic review followed the PRISMA 2020 guidelines and synthesized peer-reviewed studies retrieved from Scopus, Web of Science, and ScienceDirect, published between January 2015 and December 2025. From 500 records initially identified, 26 studies fulfilled the predefined eligibility criteria and were included in the qualitative synthesis. The findings demonstrate that evaporative cooling systems, tunnel ventilation, and automated climate control technologies consistently reduced indoor temperature (2–6°C) and improved body weight gain, feed conversion ratio (FCR), and mortality rates under hot-humid conditions. However, cooling efficiency was strongly influenced by ambient humidity, necessitating integrated and adaptive environmental control approaches. Smart sensor-based systems further enhanced microclimate stability and thermal uniformity within broiler houses. Beyond performance improvements, optimized environmental management reduced physiological stress indicators, including heterophil-to-lymphocyte ratios and corticosterone levels. Overall, integrated, humidity-adaptive, and energy-efficient cooling strategies are essential to sustain productivity, welfare, and climate resilience in tropical broiler production systems.

Poultry agribusiness is a key driver of food security and rural economic development in developing countries. However, the sector remains vulnerable to infectious diseases such as avian influenza and Newcastle disease, which can disrupt production systems and supply chain continuity. Although previous studies have examined poultry disease control, biosecurity, and supply chain disruption, evidence on how risk and crisis communication supports outbreak management and resilience in developing-country poultry agribusiness remains fragmented. This study applied a systematic literature review (SLR) approach under PRISMA guidelines to synthesize risk and crisis communication strategies in poultry disease management and their contribution to supply chain resilience. Only seven relevant studies published between 2020 and 2025 met the inclusion criteria and were analyzed using the PICO framework. Quality assessment using the Mixed Methods Appraisal Tool (MMAT), combined with systematic data extraction in Microsoft Excel 2021, was conducted to improve methodological transparency and consistency. The novelty of this review lies in integrating communication strategies, enabling and constraining factors, digital tools, One Health perspectives, and public–private collaboration within a single analytical synthesis. The findings indicate that participatory, transparent, and coordinated communication can support disease prevention and crisis preparedness, particularly when strengthened by stakeholder trust, policy support, training, and accessible information channels. However, limited digital literacy, inadequate infrastructure, and cultural barriers may reduce communication effectiveness. Overall, this review highlights the need for inclusive communication systems and collaborative governance to strengthen poultry supply chain resilience in developing countries, while recognizing that the small evidence base limits broad generalization.

Background: Low birth weight (LBW) remains a major public health concern worldwide due to its significant contribution to neonatal morbidity and mortality, as well as its long-term adverse health consequences. Pregnancy intention has been identified as a potential determinant of adverse birth outcomes; however, evidence regarding its association with LBW remains inconsistent. This study aimed to examine the association between pregnancy intention and low birth weight in Indonesia using data from the 2012 Indonesian Demographic and Health Survey (IDHS). A cross-sectional study was conducted using secondary data from the 2012 IDHS. The study included 8,922 married women aged 15–49 years who had a singleton live birth within five years preceding the survey. Pregnancy intention was categorized as intended, mistimed, and unwanted. Multivariable logistic regression analysis was performed to assess the association between pregnancy intention and LBW after controlling for potential confounding variables. The prevalence of LBW was 6.2%. After adjustment for maternal age and antenatal care (ANC) visits, no significant association was found between mistimed pregnancy and LBW (AOR = 1.055; 95% CI: 0.765–1.454). An interaction effect was identified between unwanted pregnancy and pregnancy complications. Women with unwanted pregnancies accompanied by pregnancy complications had a higher risk of delivering LBW infants compared with women whose pregnancies were intended and without complications. Nevertheless, pregnancy intention was not significantly associated with LBW overall after adjustment for confounding factors. Maternal age outside the optimal reproductive age range (<20 years or >35 years) and inadequate ANC utilization were significantly associated with an increased risk of LBW. Pregnancy intention was not independently associated with low birth weight among Indonesian women after controlling for maternal and healthcare-related factors. Maternal age and antenatal care utilization were more consistent determinants of LBW. Strengthening maternal health services, particularly adequate antenatal care and early detection of pregnancy complications, may contribute to reducing the burden of low birth weight in Indonesia.

The rapid growth of Solar Power Plant (PLTS) installations in Indonesia faces efficiency challenges due to the continuously changing position of the sun. Fixed panel systems cannot absorb solar radiation optimally throughout the day. This study aims to evaluate and compare the efficiency of various solar tracking system methods developed over the last five years using a simple literature review approach. The research method was conducted by collecting, screening, and synthesizing secondary data from five reputable scientific journals using a synthesis matrix. The review results indicate that single-axis tracking systems increase power efficiency by 15% to 24.5%. Meanwhile, dual-axis systems achieve higher efficiency, ranging from 30% to 35%, by tracking both horizontal and vertical solar movements. In terms of control systems, astronomical algorithms are found to be more reliable in cloudy weather conditions than pure light sensors. However, the internal power consumption of the actuator motors remains a critical factor that can reduce the system's net energy gain. The implication of this study emphasizes the importance of shifting future research focus toward energy-saving algorithm optimization to maximize net power yield in dynamic solar panel implementations.

The surge in young investors in the country indicates that university students are increasingly drawn to the financial markets. Unfortunately, the soundness of students' investment choices often lacks a foundation of clear reasoning, as they remain swayed by social influences, limited insight, and the rapid technological advancements that facilitate access to investment opportunities. This study aims to unravel the determinants of students' investment decisions through the lens of the Theory of Planned Behavior (TPB), focusing on financial literacy, risk tolerance, and technology—three factors frequently examined in existing literature. A qualitative approach was adopted, involving a literature review of scholarly articles published between 2020 and 2024. Data gathered from relevant academic sources were analyzed using content analysis techniques to identify research patterns, conceptual relationships, and the consistency of prior findings. The results reveal that the Theory of Planned Behavior effectively explains students' investment decisions through the interplay of attitudes, subjective norms, and perceived behavioral control. Financial literacy emerges as the most robust and consistent determinant influencing investment decisions; risk tolerance shapes investment preferences; and technology acts as a catalyst, enhancing accessibility and convenience. These findings suggest that deepening financial literacy—supported by optimal technology use and adequate risk awareness—can empower students to make investment decisions that are rational, well-calculated, and long-term oriented.
