This community service activity aimed to control the population of Aedes aegypti mosquitoes, which are the main vector of Dengue Hemorrhagic Fever (DHF), through the making and utilization of ovitraps in Sawa Village, Sawa District, North Konawe Regency. The methods applied in this program included field observation and door-to-door socialization to the community regarding the function, benefits, and procedure of making ovitraps. The socialization was designed to provide practical knowledge and raise awareness among residents about the importance of preventing mosquito breeding as part of DHF control efforts. A total of 30 households were involved as direct participants in this activity, and 30 ovitrap units were successfully made and distributed evenly to each household. The results showed that the community responded enthusiastically and expressed interest in adopting the ovitraps as a preventive measure. In addition, participants reported gaining new understanding about their active role in maintaining environmental health and reducing the risk of DHF transmission. The involvement of the community not only ensured that the ovitraps were effectively utilized, but also encouraged sustainable behavior in mosquito control practices. Overall, this program demonstrated that simple, low-cost, and community-based interventions such as ovitraps, combined with education and awareness campaigns, can contribute significantly to reducing the breeding sites of Aedes aegypti mosquitoes and lowering the potential spread of DHF in endemic areas.

The digital economy has significantly transformed economic growth by introducing innovations in payment systems and financial services. The modernization of payment instruments through monetary policy has enhanced the ability to control inflation and ensure financial system stability. This study aims to analyze the effectiveness of monetary policy and the utilization of the digital economy in maintaining financial stability in Indonesia. Using time series data from 2010 to 2024 obtained from the World Bank, this research applies the Vector Autoregression (VAR) method to examine both short-term and long-term relationships among variables, including e-money, money supply, inflation, exchange rate, interest rate, and credit card usage. The results show that e-money has a significant reciprocal influence on the money supply, while inflation is also affected by e-money and interest rates. The impulse response function demonstrates that the interactions among these variables tend to converge towards equilibrium over time. Variance decomposition analysis indicates that in the short term, e-money primarily drives financial stability, whereas in the medium and long term, the money supply plays a dominant role. Overall, the findings suggest that monetary policy, supported by digital economic systems, effectively enhances financial system stability in Indonesia. This research contributes to understanding the dual effect of digital payment innovations and provides recommendations for policymakers to strengthen financial inclusion, economic resilience, and macro-financial stability in the digital era.

Dengue Hemorrhagic Fever (DHF) remains a significant public health challenge in Indonesia, with the increasing prevalence of cases every year. One of the key methods of controlling the spread of DHF is to target the vector, Aedes aegypti mosquitoes, by eradicating their larvae. However, the widespread and continuous use of chemical larvicides has raised concerns regarding the development of mosquito resistance and environmental pollution. This community service activity aimed to provide students at Duta Karya Vocational High School with knowledge and practical skills to use natural, eco-friendly alternatives for controlling mosquito larvae, focusing on papaya seeds (Carica papaya) and alum as natural larvicides. The methods for this activity included interactive counseling, a demonstration on how to produce larvicides using papaya seeds and alum, and an engaging question-and-answer session. Thirty 12th-grade students from the Pharmacy class participated in this activity. The results revealed that the activity was highly effective in increasing the students' understanding and practical ability to independently create and apply natural larvicides. The students expressed a high level of enthusiasm and interest in the topic, actively participating in the discussions and demonstrations. As a result of this community service, the school has expressed interest in incorporating this activity into its School Health Unit (UKS) work program, which will further promote the use of natural, sustainable methods for controlling mosquito populations. The students, now equipped with the necessary skills, are ready to become "jumantik" cadres—community health volunteers responsible for monitoring and preventing mosquito larvae development. This initiative also raised awareness about utilizing organic waste, such as papaya seeds, to create valuable products for the prevention of DHF.

This study aims to analyze the dynamic relationship between population density, Gross Regional Domestic Product (GRDP) per capita, and regional economic inequality in Indonesia over the period 1995–2024. Regional inequality is measured using the Gini Ratio as a key indicator. A quantitative method with a time series approach is employed using the Vector Autoregression (VAR) model. The analysis includes unit root testing, optimal lag selection, VAR estimation, impulse response function (IRF), variance decomposition, and Granger causality testing. The results show that population density has a positive effect on regional inequality, while GRDP per capita has a negative effect. However, both variables are statistically insignificant. The impulse response analysis indicates that a shock in population density tends to increase inequality in the short term, whereas a shock in GRDP per capita tends to reduce inequality. The Granger causality test reveals that population density regional inequality, while GRDP per capita does not have a significant causal effect. Overall, the findings suggest the importance of equitable economic development and population control policies in reducing regional disparities in Indonesia.

Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus which is transmitted through the bite of Aedes aegypti or Aedes albopictus. This mosquito is a fast-growing mosquito and causes nearly 390 million people to be infected every year. The symptoms of Dengue Hemorrhagic Fever are similar to dengue fever. Dengue Hemorrhagic Fever has several other symptoms such as continuous heartburn, bleeding in the nose, mouth, gums, and bruising on the vector's skin. Dengue Hemorrhagic Fever (DHF) is an infectious disease that often causes outbreaks and causes death, especially in children. The One House One Jumantik Movement (G1R1J) is community participation and empowerment by involving every family in examining, monitoring and eradicating mosquito larvae to control vector-borne diseases, especially dengue fever, through the cultivation of 3M PLUS Mosquito Nest Eradication.

FEVD analysis results show a leading indicator as an operational target. Then the results of the ARDL Panel analysis show that the Inflation Panel, Total Money Supply, Interest Rates, Gross Domestic Product, Government Expenditure, TAX Revenue, and Wages are able to control economic stability, precisely at the unemployment rate in the 6 in the world’s highest unemployment countries back in the short term, as well as long-term.

This study aims to determine the effect of monetary policy on economic growth. This study uses the Vector Autoregression method by completing the assumption test and estimation on the research variables of inflation, investment, credit, interest rates and gross regional domestic product. Time series research data from 2003-2022 sourced from the Central Bureau of Statistics of North Sumatra (BPS) SUMUT with the results obtained are inflation and interest rates give the results that inflation is influenced by investment and credit, until investment affects gross regional domestic product. Then credit also affects inflation and interest rates and gross regional domestic product is influenced by investment and credit. Thus, in determining policies that encourage economic growth the government must consider a more coordinated monetary policy strategy to deal with the dynamics of strengthening interest rates, controlling inflation, can be measures that support economic stability.

Abstract. Dengue Hemorrhagic Fever (DHF) is an infectious disease caused by the dengue virus and transmitted through the bite of the Aedes aegypti mosquito. This disease continues to be a serious health problem in Indonesia, with high incidence rates in various regions, including rural areas. Efforts to prevent DHF are often focused on controlling mosquito vectors through various methods, one of which is the use of insecticides. However, the use of chemical insecticides can have negative impacts on human health and the environment. Therefore, this research develops a natural alternative in the form of Anti Mosquito Spray and Hand Sanitizer made from lemongrass (Cymbopogon citratus). Lemongrass was chosen because it contains citronella, a compound proven to have activity as a repellent or mosquito deterrent. This study aims to evaluate the effectiveness of lemongrass-based mosquito repellent spray as well as its capability as a hand sanitizer. The results show that this product is not only effective in preventing mosquito bites but also safe to use as a hand sanitizer, making it a practical and environmentally friendly solution in the prevention of DHF.

This study examines the influence of monetary policy, particularly interest rates, on economic stability in the TIMI countries (Thailand, India, Malaysia, and Indonesia). It underscores the vital role of interest rates in controlling inflation and stimulating economic growth. Utilizing a Vector Autoregression (VAR) model, the research analyzes the reciprocal relationships between crucial economic indicators such as GDP, CPI, exchange rates, consumption, interest rates, and trade balances from 2008 to 2022. For instance, adjustments in interest rates can influence investment levels, consumption patterns, and inflation rates, thereby affecting overall economic activity. The Granger causality tests indicate that short-term relationships between these variables are insignificant, but long-term interactions are evident. This supports the Johansen cointegration results, which confirm two cointegrated equations at the 5% significance level. The study emphasizes maintaining interest rate stability for sustainable economic growth and price stability. It highlights that fluctuations in interest rates, influenced by global economic conditions and domestic economic policies, play a crucial role in the economic performance of TIMI countries. Recommendations for central banCM include implementing responsive and adaptive interest rate policies to manage inflation, foster economic growth, and maintain exchange rate stability. This approach is essential for addressing disparities in income, education, healthcare, and technology access, which are critical for equitable economic development. In conclusion, this research underscores the importance of a nuanced understanding of monetary policy's impact on economic stability and the need for coordinated efforts between fiscal and monetary authorities to achieve long-term

This study aims to analyze the effect of money supply (JUB), e-money transactions, and the BI 7-Day Reserve Repo Rate on the inflation rate in Indonesia in the period 2012 to 2021. The background of this research is based on the increasing use of non-cash transactions and the dynamics of monetary policy in maintaining price stability. The method used in this study is the Vector Error Correction Model (VECM) to measure the short-term and long-term relationship between variables. The analysis shows that JUB and e-money have a positive influence on inflation in the long run, while BI 7-Day Rate has a negative and significant effect on inflation. Simultaneously, the three variables show a significant relationship with inflation, indicating the importance of controlling monetary instruments in maintaining price stability in Indonesia. This study contributes to the understanding of the role of payment system innovation and interest rates in controlling national inflation.

The learning of physics, particularly mechanics, poses significant challenges for high school students. Concepts such as Newton’s laws, energy, and three-dimensional vectors are often difficult to grasp using traditional teaching methods. Virtual Reality (VR) has emerged as a promising solution by providing an immersive and interactive learning environment. This study aims to evaluate the effectiveness of VR-based learning media in enhancing students’ understanding of physics concepts, with a specific focus on mechanics. An experimental design was employed, consisting of two groups: an experimental group using VR for learning and a control group receiving traditional instruction. Pre-test and post-test assessments were used to measure the improvement in students' conceptual understanding of physics. The findings indicate that students in the experimental group demonstrated a significant improvement in their understanding of complex physics concepts, such as projectile motion, force, and Newton’s laws, compared to the control group. Students in the experimental group also exhibited higher levels of engagement and motivation, with VR's immersive nature encouraging active participation in learning. The study concludes that VR is an effective tool for enhancing students’ comprehension of abstract and complex physics concepts, improving their visualization and problem-solving skills. Furthermore, VR-based learning provides students with opportunities to conduct virtual experiments and simulations that may not be possible in traditional classroom settings. The implications of this study suggest that VR should be integrated into the physics curriculum to improve learning outcomes, especially in schools with access to the necessary technology. Educators and curriculum developers are encouraged to explore VR’s potential in fostering a more engaging and effective physics education.
