Keywords: Poverty. Quality of human resources. Income Inequality and Open Unemployment Rate Introduction Poverty is a complex and multidimensional problem and cannot be seen easily only from an absolute number. Poverty is also the main menu presented, especially in developing countries, creating prosperity for the people is the ultimate goal of a country, welfare is closely related to poverty. In theory, poverty can be said where there is an inability to meet household or family needs such as eating, drinking, shelter, clothing, education and health. (Sukirno, 2. The World Bank sets an international poverty line of $2 US dollars per capita per day. This means that people who are considered poor in all countries in the world are those whose expenses are less than $2 per day. In the Indonesian context, the measure commonly used is the poverty line. Several findings in the problem of urban poverty have mixed results, (Pitri Yandri, 2. In the case of the poor, it can be explained that the tendency to save . arginal propensity to savin. MPS = 0 and the tendency to consume . arginal propensity to consume / MPC) is close to 1, because Almost all of the income earned is used for consumption. The problem of provincial poverty is inseparable from various aspects in each region. In this study, the problem of poverty is studied in the province of Sumatra.

Based on Figure 1, the highest average number of poor people in 10 provinces on Sumatra Island in 2017-2021 is North Sumatra Province with an average of 2639,378 thousand people. South Sumatra with 2178,17 thousand people and Lampung with 2148,314 thousand people, while the areas with the lowest number of poor people are Bangka Belitung with 143,016 thousand people and the Riau Islands with 264. 77 thousand people. Ritonga . Poverty is a condition of life that is completely deprived experienced by a person or household so that they are unable to meet the minimum or decent needs for their One of the factors of the Human Development Index is a concept that influences each other, in the classical concept of development it is defined as an increase in economic growth and can help in reducing poverty levels. Salcatore . argues that there is a direct positive effect between the high growth of human development on economic growth. The following is a description of the Human Development Index of 10 Provinces on the Island of Sumatra: Figure 2. Average Human Development Index of 10 Provinces in Sumatra Island From Figure 2 it can be seen that the average Human Development Index is the highest in 10 provinces on the island of Sumatra in 2017-2021. Human development is an important component in the formation of human capital in each region. In the figure data, the average range of the human development index in the Sumatran regions is at 70. 3 regions with the highest numbers covering the Riau Archipelago Province of 75. Riau Province of 72. and West Sumatra Province of 72,028, while the lowest value is only in 2 regions, namely International Journal of Economics.

This human development index is the result of several components, namely health rates, expected years of schooling and adjusted Real Expenditure per Capita. Singh . clearly reveals that HDI and per capita income have a major influence on poverty reduction. The effect of HDI and per capita income on poverty alleviation was found to be significant and the impact of HDI on poverty was negative. Furthermore. Arief and Pratiwi's research . concludes that the HDI indicator has a negative relationship and has a significant effect on statistical poverty reduction. In several studies on poverty hacking income inequality has a role in existing poverty cases. Nisa et al. found that income inequality has a significant and negative effect on poverty in the Province of the Bangka Belitung Islands. The following is an overview of the Gini Ratio in 10 provinces on the island of Sumatra: Figure 3. Average Gini Ratio of 10 Provinces in Sumatra Island 2017-2021 Based on Figure 3, the average Gini ratio of 10 provinces on Sumatra Island in 20172021. Overall, the Sumatran regions are included in the moderate level of income inequality, as can be seen from the average value which is around 0. In the figure, the highest Gini ratio value is in 3 regions, namely South Sumatra Province of 0. Riau Islands Province 3416 and Bengkulu Province of 0. 3354 but the value range of this number is still in the category of moderate inequality. while the lowest average Gini ratio was in Bangka Belitung Province which touched a figure of 0. But different things have been found that with the level of inequality which tends to be moderate, the Sumatran region still has a relatively high poverty rate. Yusuf et al. Ahmad . Gitting . Mahardiki and Santoso . Nurhuda at al. in East Java Baransano at. in West Papua. Barika . in Bengkulu Province. said there had been development imbalances both at the provincial and district levels within the region. Therefore, the development of the leading sectors of each region must be increased in each region, so that it can spur regional growth and ultimately accelerate the reduction of inequality and poverty. This is important because by reducing inequality development aims to reduce the level of debt in the region. The understanding of the importance of the role of employment in the relationship between economic growth and poverty alleviation is based on the arguments of Jonaidi . and Awandari & Indrajaya . , that high economic growth should provide many Jonaidi . explains that job opportunities play an important role in influencing economic growth to reduce poverty. Labor has a close relationship with the unemployment rate, where a region must be able to absorb labor as a form of reducing the existing unemployment rate. International Journal of Economics.

Average Open Unemployment Rate of 10 Provinces in Sumatra Island Figure 4, shows that the average Open Unemployment rate is from 2017-2021. The unemployment rate is one of the important variables in the case of poverty in areas on the island of Sumatra. In the provinces of Sumatra Island, some of the highest unemployment rates include the Riau Archipelago Province at 8. Aceh Province 6. 394% and West Sumatra Province at 6. 004, while for areas with low levels. Bengkulu Province is 3. Bangka Belitung Islands Province at 4. 25% and Lampung Province at 4. The size of poverty in an area can be seen or known by using a number of measuring tools commonly called poverty indicators, namely: income or consumption per week/month/year, assets, total wealth, food consumed, housing, formal education, basic infrastructure household, and health. Sukirno S. and Tambunan T. However, recent literature on this issue suggests that macroeconomic factors influence poverty in a nonlinear manner. Prasetyoningrum . found that unemployment has a positive effect on poverty levels and has a significant effect. Saleem et al. shows that multidimensional poverty is significantly more in rural areas than in urban areas. A recent study conducted by Meo et al. also states that various macroeconomic variables including unemployment affect poverty asymmetrically.

The Human Development Index has composite indicators in its calculation, including life expectancy, literacy rates, and per capita Improvements in the health and education sectors as well as income per capita contribute to human development, so that the higher the quality of human beings in an area will reduce the number of poor people in the area. The following is a description of the HDI and the percentage of poor people. The following are the results of accumulated data on the Human Development Index and poverty in 10 provinces on the island of Sumatra : Figure 6. Average Human Development Index and Percentage of Poor Population in 10 Provinces on Sumatra Island in 2017-2021. This can be seen from the comparison of several areas of 10 provinces on the island of Sumatra where when the human development index increases, poverty tends to decrease, in the data the Riau archipelago has the highest average HDI level of 75. 2% with a low poverty level, then Riau region has a high average HDI level of 72. 6% with a low poverty rate, and the Lampung region has a low average HDI level of 69. 3% with a poverty rate that continues to increase for the Bengkulu region has an average A low HDI of 71. 0% with an increasing poverty rate.

Lincolin Arsyad . states that there is a very close relationship between high levels of unemployment and poverty. For most people, those who do not have permanent or parttime jobs are always among the very poor. People who work for a fixed fee in the public and private sectors are usually among the upper middle class group of people. Everyone who does not have a job is poor, while those who work fully are rich. Because sometimes there are also workers in urban areas who do not work voluntarily because they are looking for better jobs that are more in line with their education level. They reject jobs that they feel are inferior and they behave that way because they have other resources that can help with their financial People like this can be called unemployed but not necessarily poor. Similarly, there are many individuals who may work full-time per day, still earning a meager income. Many independent workers in the informal sector are fully employed but often remain poor.
