Dengue Hemorrhagic Fever (DHF) is a contagious disease caused by the Aedes aegypti mosquito, commonly found in Indonesia, particularly in areas with poor environmental sanitation. The implementation of Clean and Healthy Living Behavior (PHBS) is one of the effective strategies for controlling mosquito vectors and preventing DHF. This community service activity aims to improve public understanding and participation in the application of PHBS in Sungai Pangeran Village, Palembang, through counseling, training of Larvae Monitoring Officers (Jumantik), and community clean-up activities with the 3M Plus Movement (Draining, Closing, Burying, and additional measures). The results showed a significant increase in public knowledge about PHBS and active participation in mosquito larvae monitoring. The training of Jumantik created cadres capable of performing independent monitoring, and the community clean-up activities reduced potential mosquito breeding sites by 60%. Monitoring also showed a 35% decrease in DHF cases after the program. This activity has proven effective in raising public awareness and reducing vector-borne disease risks in the local environment. However, continued monitoring and support from local governments are needed to sustain the program.

This study aims to analyze the optimalization of monetary policy and fiscal policy (current policies) in stabilizing the economy, to be precise in overcoming the unemployment rate during the pandemic in the 6 world’s highest unemployment countries (South Africa, Colombia, Philippines, Brazil, Chile, and United States). Where the monetary variables (Total Money Supply and Real Interest Rates), fiscal policy (government expenture and TAX revenue), and economic stability (inflation, GDP, and wages). This study uses secondary data or time series from 2005 to 2019. The data analysis models in this study are Simultaneous Regression, Vector Autogression (VAR) model, and ARDL Panel seen from sharpening with Impulse Response Function (IRF) analysis, and Forecast Error Variance Decomposition (FEVD), and ARDL Panel.

Dengue Fever is caused by the dengue virus transmitted by humans through the bite of Aedes aegypti and Aedes albopictus mosquitoes previously infected with dengue virus from other dengue fever patients. The problem is that there is no vaccine or anti-viral drug for dengue hemorrhagic fever, an extraordinary event of dengue hemorrhagic fever if in the community: someone dies or the mortality rate is fifty percent of the previous one and in one month the number of dengue cases doubles from the previous year. Epidemiological control of the presence of mosquitoes through the 3M movement and the larva-free rate (ABJ) ≥ 95% of the national target. Alternative Fogging is carried out if three or more patients with unexplained fever are found and more than or equal to five percent of larvae are found. Therefore, it is necessary to observe the larval stage of DHF vectors to determine the distribution, mosquito density, the main habitat of larvae, and the alleged risk of transmission. The purpose of this study was to determine the House Index, Container Index, Bruteau Index, Density Figure and ABJ through a larval survey. The sampling technique used proportional random sampling. Research instruments: questionnaires, observation sheets, flashlight equipment to check for the presence of larvae. Results HI, BI and CI Habitat Index > 5%. The larva free rate in Sumberejo Prosperous Village was 87%, indicating a moderate density of potential dengue transmission, because it was below > 95%.

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. Abstrak. Demam Berdarah Dengue (DBD) merupakan penyakit menular yang disebabkan oleh virus dengue dan ditularkan melalui gigitan nyamuk Aedes aegypti. Penyakit ini terus menjadi masalah kesehatan serius di Indonesia, dengan tingkat kejadian yang tinggi di berbagai wilayah, termasuk daerah perdesaan.

Oleh karena itu, penelitian ini mengembangkan alternatif alami dalam bentuk Anti Mosquito Spray and Hand Sanitizer yang berbahan dasar serai (Cymbopogon citratus). Serai dipilih karena mengandung senyawa sitronela yang terbukti memiliki aktivitas sebagai repelan atau pengusir nyamuk. Penelitian ini bertujuan untuk mengevaluasi efektivitas spray anti nyamuk berbahan dasar serai serta kemampuannya sebagai pembersih tangan. Hasil penelitian menunjukkan bahwa produk ini tidak hanya efektif dalam mencegah gigitan nyamuk, tetapi juga aman digunakan sebagai pembersih tangan, sehingga dapat menjadi solusi praktis dan ramah lingkungan dalam upaya pencegahan DBD.

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

Flies are vectors for disease transmission, especially mechanically and through their vomit and feces. Items, especially food, are usually contaminated by human feces, rubbish, the saliva of sick people, scars from animal carcasses and other things that are covered in flies. Flies can throw feces on food so that the food becomes contaminated with fly eggs and larvae. Disruption of comfort, eyesore, itching of the skin, causing discomfort, decreased appetite.
