Osteoporosis is a metabolic bone disorder characterized by a decrease in bone density and strength, making bones more fragile and susceptible to fractures. People with osteoporosis often complain of pain. One of the pain management methods for osteoporosis patients is progressive muscle relaxation. This community service activity empowers the public to practice progressive muscle relaxation techniques. The pre-test results showed that the majority of the community’s knowledge about osteoporosis and pain management was in the poor category, at 79.5%. After education and simulation of the progressive muscle relaxation technique were conducted, there was an increase in the community’s knowledge about osteoporosis and pain management, with 61.4% in the good category. The conclusion of this community service activity is that empowering the community to independently perform progressive muscle relaxation techniques is very beneficial in reducing pain in people with osteoporosis.

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.

Socialization on the prevention of Dengue Hemorrhagic Fever (DBD) in Kebonadem Village on July 20 2024 aims to increase public awareness about the dangers of DBD and steps to prevent it. The main problem faced is the high risk of dengue fever transmission due to population density and community behavior that does not maintain environmental cleanliness, which supports the breeding of the Aedes aegypti mosquito. The urgency of this outreach is very high considering that dengue fever cases often cause Extraordinary Events (KLB) and the fatal impacts they can have. The results of this outreach show a significant increase in public understanding regarding preventive measures such as the application of 3M Plus (Draining, Covering, Burying and Sprinkling abate powder) as well as the early signs of dengue fever. Active participation in discussions and implementing new habits, such as cleaning water reservoirs, indicates the positive impact of this activity. Despite progress, consistency in implementing prevention habits and ongoing support from various parties is still needed to ensure long-term success. Regular evaluations will help assess the effectiveness of the program and reduce the number of dengue cases in the village, making it an example of success in dengue prevention in other communities.

The small number of people cultivating horticultural crops, especially vegetables, means that people can only buy vegetables to meet their vegetable food needs, where the main factor for this is the decline in the area of productive land used as agricultural land and cultivation caused by the growth of population density in Indonesia. Therefore, the solution to the existing problem is to provide openness of insight and assistance in utilizing narrow land for plant cultivation. One way to cultivate plants is by using the vertical cultivation method. In implementing this activity, the aim is for Kalijudan residents to have knowledge about the vertical cultivation system and plastic bottle waste management. The implementation of this activity uses the method of socialization and training activities or direct practice. Where, the target audience in the practice of this activity is elementary school students and Kalijudan residents. From the results of the discussion, it was concluded that this activity is useful because it can introduce residents and change the condition of the Kalijudan sub-district which was originally a narrow land without plants into a narrow but green land. In addition, this vertical cultivation activity also has benefits in reducing plastic waste that accumulates in the Kalijudan environment.
