Abstract

Poverty, unemployment, and human development are closely intertwined and remain persistent challenges in Indonesia, particularly in the wake of the COVID-19 pandemic. This study investigates the influence of unemployment, economic growth, and the Human Development Index (HDI) on poverty in Indonesia over the period 2013–2024, using 48 quarterly observations sourced from Statistics Indonesia (BPS). Anchored in Islamic economic thought, the analysis incorporates the concept of maslahah. The pursuit of public benefit and welfare as a normative foundation for development. A quantitative method is employed using the Error Correction Model (ECM), which enables the examination of both short-term fluctuations and long-term relationships among variables. The results show that, in the short term, rising unemployment significantly exacerbates poverty, while in the long term, improvements in economic growth and HDI are effective in alleviating poverty levels. These findings highlight the need for integrated and sustained efforts to enhance human capital, generate employment, and ensure inclusive economic progress. Policy frameworks inspired by maslahah can help ensure that anti-poverty strategies are not only economically effective but also ethically grounded, thereby supporting the broader objectives of the Sustainable Development Goals (SDGs).

Abstract

This research aims to determine the influence of government spending in the fields of education, social protection, public services, infrastructure, community empowerment, investment, and the Human Development Index (HDI) on economic growth in Indonesia's 3T (Disadvantaged, Frontier, Outermost) regions. This study employs quantitative research methods, with a population and sample comprising 62 regions designated as 3T in Indonesia. Data analysis was conducted using panel data regression analysis with the EViews 10 software. The results reveal that government spending on education (BFPEND), public services (BFPU), and community empowerment (BDPM) does not significantly influence economic growth. However, government expenditures on social protection (BFPS) negatively and significantly affect economic growth, while spending on infrastructure (BFINF) and investment (INVEST) positively and significantly impact economic growth. Additionally, the HDI has a negative and significant effect on economic growth. Collectively, government spending across these sectors, along with HDI, has a positive and significant effect on economic growth in Indonesia's 3T regions. A comparison of the average HDI in Disadvantaged Regions versus Frontier and Outermost Regions in Indonesia is also presented.

Abstract

This study examines the impact of government expenditure in education, social protection, public services, infrastructure, community empowerment, investment, and the Human Development Index (HDI) on economic growth in Indonesia’s Disadvantaged, Frontier, and Outermost (3T) regions before and after the COVID-19 pandemic. Employing a quantitative approach, this research analyzes panel data from 62 regencies categorized as 3T regions from 2017 to 2022. The study uses panel data regression analysis to evaluate the influence of these expenditures on economic outcomes. Findings indicate that government spending in the education sector consistently had a positive effect on economic growth before and after the pandemic. Conversely, expenditure in social protection and HDI shifted from having a positive to a negative impact post-pandemic. Meanwhile, investments in public services, infrastructure, and overall investment, which previously had a negative impact, showed a positive influence in the post-pandemic period. Overall, government spending across all sectors had a simultaneous and significant positive effect on economic growth in the 3T regions. These results underscore the need for evidence-based policy interventions to enhance the effectiveness of government spending in promoting equitable economic growth in underdeveloped areas.

Abstract

The process of erosion leads to the loss of fertile topsoil and a reduction in the soil's capacity to store and absorb water. At the research site, community oil palm plantations in Tanjung Pasir Village, Kualuh Selatan District, North Labuhanbatu Regency, land clearing was conducted through logging, and in some cases, burning. Subsequent plantation management was carried out without implementing soil conservation measures and while disregarding environmental factors, resulting in soil degradation and productivity decline linked to erosion. This study aims to predict the magnitude of erosion using the Universal Soil Loss Equation (USLE) method, calculate the tolerable soil loss, and analyze the erosion hazard level. The USLE method was applied by calculating the causative factors of erosion: rainfall erosivity (R), soil erodibility (K), slope length and steepness (LS), cover management (C), and conservation practices (P). The predicted erosion values were then compared to the tolerable soil loss values to determine the necessity of conservation interventions. The results indicate that the highest predicted erosion value (A) was 521.73 tons/ha/year on plot KS1, while the lowest was 111.09 tons/ha/year on plot KS5. Meanwhile, the tolerable soil loss (TSL) ranged from 43.86 to 64.38 tons/ha/year. Based on this comparison, two classes of erosion hazard were identified: very high and high. Both classes exhibited predicted erosion values far exceeding the permissible limits. Therefore, conservation measures are imperative, one of which involves planting dense Legume Cover Crops (LCC).
