This study aims to analyze the phenomenon of tax burden, tax compliance, and tax-saving strategies and their influence on business survival strategies in Indonesia’s retail and trade sector amid the economic slowdown in 2026. Indonesia’s economic growth declined to 4.2% in the first quarter of 2026 from 5.1% in the previous year, creating considerable pressure on business sustainability, particularly in the retail and trade sector. This research employed a quantitative approach using a survey method involving 120 retail and trade business owners located in Jakarta, West Java, and Banten. Respondents were selected through purposive sampling. Data were collected using a structured questionnaire that met validity and reliability requirements and were analyzed using multiple linear regression with SPSS version 26 after fulfilling the classical assumption tests. The results indicate that tax burden (B = 0.287; p < 0.001), tax compliance (B = 0.341; p < 0.001), and tax-saving strategies (B = 0.398; p < 0.001) each have a positive and significant effect on business survival strategies, both individually and simultaneously. The F-test (F = 62.847; p < 0.001) confirms the overall significance of the regression model, while the coefficient of determination (R² = 0.621) shows that the three independent variables explain 62.1% of the variance in business survival strategies. These findings suggest that effective tax management, combined with the lawful utilization of tax incentives, plays a crucial role in strengthening business resilience and ensuring the sustainability of retail and trade businesses during periods of economic uncertainty.

Musi Rawas Utara Regency is categorized as an underdeveloped, frontier, and outermost (3T) region that still faces serious challenges in human development, particularly within the education dimension. Although the Human Development Index (HDI) indicates an upward trend, the School Enrollment Rate (SER) and the mean years of schooling at the secondary education level remain relatively low and lag behind other regions. This condition is influenced by limited access to secondary education, household economic vulnerability, and disparities in the quality and distribution of educators in remote areas. This policy paper aims to analyze secondary education issues as a primary obstacle to increasing the HDI of Musi Rawas Utara Regency and to formulate effective and sustainable policy alternatives. The method used is a qualitative descriptive analysis through a literature study, utilizing data from the Central Bureau of Statistics (BPS), regional planning documents, as well as relevant national regulations and policies. The analysis was conducted using a SWOT approach to identify the strengths, weaknesses, opportunities, and threats of the regional education policy. The results of the study show that improving the HDI requires integrated, affirmative, and region-based education policies. Three main policy alternatives recommended include expanding and equalizing access to secondary education, strengthening educational assistance and social protection for vulnerable families, and sustainably distributing and improving teacher quality. The implementation of these policies is expected to increase the SER, extend the mean years of schooling, and strengthen the quality of human resources as a foundation for sustainable development in Musi Rawas Utara Regency.

Namun, ada empat tantangan utama, yaitu kurangnya konsistensi konten di berbagai akun SPPG, ketimpangan digital di daerah 3T, ketiadaan mekanisme tindak lanjut resmi, dan potensi kriminalisasi partisipasi masyarakat. Penelitian ini merekomendasikan model optimalisasi yang mencakup standardisasi konten, perlindungan partisipasi masyarakat, serta integrasi dengan sistem pengawasan resmi untuk memperkuat transparansi dan akuntabilitas MBG dengan pendekatan digital.

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.

Cattle farming plays a strategic role in rural economic development by generating employment, supplementary household income, and contributing to food and nutritional security. However, in Indonesia, most smallholder cattle enterprises remain traditional and small-scale, leading farmers to treat livestock farming primarily as a secondary livelihood. While previous studies have largely focused on technical adoption and production performance, limited attention has been given to farmers’ psychological interest as a foundation for sustaining livestock enterprises. Therefore, this study aims to analyze the level of community interest in cattle farming and examine the influence of farmers’ characteristics (age, education level, herd size, number of family dependents, farming experience, and primary income) on such interest. A quantitative survey was conducted involving 34 cattle farmers in Taji Village, Jabung District, Malang Regency, selected using total sampling. Data were collected through structured questionnaires and analyzed using multiple linear regression. The findings reveal that community interest in cattle farming is generally high, as reflected in emotional (3.93), cognitive (3.81), and conative (3.74) dimensions measured on a four-point Likert scale. Regression results indicate that age has a significant positive effect (p = 0.022), whereas farming experience has a significant negative effect (p = 0.025) on interest levels. Other variables show no statistically significant influence. These findings highlight that psychological engagement in cattle farming is shaped more by demographic and experiential factors than by formal education or income level. The study contributes to the literature by positioning interest as a psychological determinant of livestock sustainability. Policy implications emphasize the urgency of risk-mitigation extension programs to address farmer burnout, incentivized intergenerational knowledge transfer, and cooperative-based institutional support to ensure smallholder livestock sustainability.

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.

Open burning of household waste remains the dominant waste disposal practice in rural areas of Indonesia, posing significant risks to public health and environmental quality. This community service activity aimed to provide an innovative, low-smoke waste combustion solution — the rocket stove incinerator — to the residents of Dusun Allukeke, Desa Belapunranga, Kecamatan Parangloe, Kabupaten Gowa. A baseline survey conducted during PBL 1 revealed that 87.6% of households disposed of waste through open burning. An asset-based community development (ABCD) approach was adopted, engaging community members at every stage from planning, construction, to utilisation. The rocket stove was constructed over three days using locally available materials and was demonstrated to significantly reduce visible smoke emissions compared to conventional open burning. The technology works through a vertically insulated combustion chamber that promotes near-complete combustion, reducing waste volume by 50–90% while suppressing particulate matter and hydrocarbon emissions. Community participation strengthened local ownership of the solution. This activity demonstrates that appropriate technology co-constructed with communities can serve as a practical, sustainable, and replicable model for rural waste management.

Acute Respiratory Infection (ARI) remains a major public health problem in Indonesia. Based on the 2025 National Health Reporting System survey, ARI ranked first among diseases with the highest number of cases, reaching more than 14.5 million cases. This study aimed to determine and analyze the relationship between environmental sanitation and nutritional status with the incidence of ARI among children under five following flood disasters in the working area of Panteraja Community Health Center, Pidie Jaya Regency. The study employed a quantitative method with an analytical observational design using a case-control approach. The dependent variable was the incidence of ARI among under-five children, while the independent variables were environmental sanitation and nutritional status. The sample consisted of 122 children under five, including 61 children with ARI and 61 children without ARI. The results of the chi-square test showed a significant relationship between environmental sanitation and ARI incidence (p = 0.000; OR = 0.042; 95% CI = 0.014–0.133), as well as between nutritional status and ARI incidence (p = 0.000; OR = 0.011; 95% CI = 0.001–0.083). These findings indicate that poor environmental sanitation and inadequate nutritional status contribute to the occurrence of ARI among children under five after flooding. Therefore, promotive and preventive efforts, along with regular monitoring of children's nutritional status, are essential to reduce the risk of ARI.

This study compared the performance of SARIMA and Prophet models in forecasting daily close prices of three major Indonesian banking stocks: BBCA, BBRI, and BMRI, using data from January 2020 to March 2026. Data were retrieved via the yfinance library, preprocessed, and split into 80% training and 20% testing sets. SARIMA modeling followed the Box-Jenkins procedure, while Prophet was configured with a Lag-1 regressor, weekly and monthly seasonality, Indonesian public holidays, and log transformation. Model performance was evaluated using MAPE, MSE, and Dstat metrics. Results showed that SARIMA outperformed Prophet in MAPE and MSE across all six stock-variable combinations, with MAPE values ranging from 1.3368% to 1.9386% for SARIMA and 1.5992% to 2.2300% for Prophet. However, Prophet demonstrated marginally higher Dstat values in several series. Both models achieved "Very Good" forecasting accuracy. A web-based forecasting system was also developed using Streamlit to make the models accessible to investors.

Colorectal cancer and paralytic ileus are significant health concerns worldwide, including in Indonesia, where their prevalence and mortality rates have shown concerning trends. This study aims to compare the prevalence and mortality of paralytic ileus and colorectal cancer in Indonesia using data from the Global Burden of Disease (GBD) for the years 2019, 2021, and 2023. A secondary data analysis was conducted using GBD 2023 data, focusing on prevalence, incidence, and mortality rates for both conditions across 34 provinces in Indonesia. The study employed a time-trend analysis to observe the changes in disease burden over the specified years, along with examining the differences in disease characteristics based on sex, age groups, and regions. Results indicated that colorectal cancer has a higher burden of disease, with significantly higher prevalence and mortality rates compared to paralytic ileus. This highlights the urgent need for enhanced prevention, early detection, and management strategies for colorectal cancer in Indonesia. The findings emphasize the importance of integrated healthcare policies to address both conditions effectively, focusing on regions with the highest disease burden. Further research is recommended to explore the underlying risk factors and to evaluate the effectiveness of current healthcare interventions.

Stunting is a chronic nutritional problem that remains a major public health challenge in Indonesia, including in Ngombakan Village, Polokarto District, Sukoharjo Regency. Moringa leaves (Moringa oleifera Lam.) are known as a superfood plant with nutritional content far exceeding conventional food ingredients, including protein, vitamin A, calcium, potassium, iron, and vitamin C, making them highly potential as a functional food for stunting prevention. This community service activity aims to improve the knowledge of mothers at the Posyandu of Ngombakan Village about stunting and the benefits of moringa leaves, while also introducing the innovation of moringa leaf pudding as a nutritious supplementary food for toddlers. The activity was carried out from August 13 to September 6, 2024 through 6 meetings at the posyandu using lecture methods, leaflet distribution, and pudding-making demonstrations. The results showed a significant increase in mothers' knowledge about stunting and the nutritional content of moringa leaves, as well as positive enthusiasm from participants in accepting moringa leaf pudding as an affordable and nutritious supplementary food alternative for toddlers.

Bilingual instruction is a learning strategy that can help students understand learning materials while bridging the gap between the language used at school and the language spoken in daily life. This study aims to analyze the effect of bilingual instruction on students' understanding of the Ecosystem topic at SDK Gusung Karang, Koja Gete Village. The study was motivated by the fact that students predominantly use the Sikka language in their daily communication, making it difficult for them to understand lessons delivered solely in Indonesian. This study employed a qualitative approach with a descriptive method. The research participants consisted of the fourth-grade homeroom teacher and fourth-grade students at SDK Gusung Karang. Data were collected through observations, interviews, and documentation and analyzed using data reduction, data display, and conclusion drawing techniques. The findings indicate that bilingual instruction has a positive impact on students' understanding of the Ecosystem topic. The use of the Sikka language helps students comprehend basic concepts, increases classroom participation, and enhances their confidence during the learning process. Meanwhile, Indonesian strengthens students' mastery of scientific terminology and academic language skills. Although students still experience difficulties in consistently using scientific terms in Indonesian, bilingual instruction improves their understanding and connects learning concepts with their real-life experiences. The effectiveness of this strategy depends on teachers' ability to manage language switching in a structured and consistent manner.

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.

Stroke remains one of the leading causes of mortality and disability worldwide, including in Indonesia. The increasing prevalence of stroke and Years Lived with Disability (YLD) reflects its growing health burden. This study aimed to analyze trends in stroke prevalence and YLD in Indonesia during 2021–2023 using data from the Global Burden of Disease (GBD). A quantitative descriptive design with an ecological and time-trend approach was employed. Secondary data were obtained from the GBD Results Tool and analyzed using R version 4.4.1. The analysis focused on major geographical regions across Indonesia. The results showed a gradual increase in both stroke prevalence and YLD during the study period. Java recorded the highest prevalence and YLD, while Maluku and Papua showed lower prevalence but greater variation in YLD. These trends were associated with urbanization, unhealthy lifestyles, hypertension, diabetes, and unequal access to healthcare and rehabilitation services. Pearson correlation analysis demonstrated a very strong association between stroke prevalence and YLD (r > 0.99) across all years. The findings highlight increasing stroke burden and regional disparities, emphasizing the need for equitable healthcare access, risk factor control, and strengthened post-stroke rehabilitation programs.
