Abstract

High unemployment has become a significant issue in the province, which has great economic potential but faces challenges in reducing unemployment. In this analysis, economic and employment data of North Sumatra Province during the period were used to understand the relationship between inflation, minimum wage, and unemployment rate. The results of the analysis show that inflation has a significant influence on the unemployment rate in North Sumatra Province. High inflation can reduce people's purchasing power and create uncertainty in the labor market. In addition, the study also found that the minimum wage plays an important role in influencing the unemployment rate. Setting a minimum wage that is unbalanced or too high compared to labor productivity can limit the growth of new jobs.

Abstract

Transtibial amputation affects balance and the ability to perform daily activities. The use of a transtibial prosthesis can improve mobility, but still has the potential to cause dynamic balance disorders that have an impact on independence. This study aims to determine the relationship between dynamic balance and daily activities in transtibial prosthesis users. This research is an observational analytic study with a cross-sectional approach conducted in January 2025 at the IPOED False Foot Clinic. The study subjects consisted of 12 transtibial prosthesis users selected by purposive sampling from a total population of 31 people, based on the inclusion and exclusion criteria. Data were analyzed using normality test and Spearman Rank correlation test. The results of the analysis showed a p value of 0.207 (p> 0.05), which means that there is no statistically significant relationship between dynamic balance and daily activities in transtibial prosthesis users. The correlation coefficient value of -0.392 indicates a moderately negative relationship. This means that an improvement in balance is not always accompanied by an increase in daily activities, but this relationship is not statistically significant. The results showed no significant relationship between dynamic balance and daily activities in transtibial prosthesis users. This finding can be the basis for further research and consideration in developing a more targeted rehabilitation program.

Abstract

Lower back pain (Low Back Pain or LBP) is one of the most common musculoskeletal complaints experienced by women, especially those involved in household activities or caring for toddlers. Activities such as bending, lifting loads, or non-ergonomic breastfeeding positions are major risk factors. Based on this, education about "Proper Body Mechanics" becomes essential to prevent and reduce LBP. The goal is to increase the knowledge of mother members of the Persit Kartika Chandra Kirana in Koramil Jebres regarding correct posture and techniques in daily activities, measure the effectiveness of education through pre-test and post-test methods, and provide practical skills so that they can reduce or prevent LBP complaints. The community service method involves educating women with lower back pain (LBP) about proper body mechanics, which can be conducted in several stages. Educational activities on proper body mechanics have been proven effective in increasing the knowledge and awareness of the wives of Persit Koramil Jebres regarding the prevention and reduction of LBP from 53% to 77%.
