Abstract

Labor absorption is an important factor in supporting economic development through national income. The low level of employment is still a problem in various regions in Indonesia, especially in Central Java Province. The problem of employment, can be overcome by maximizing the factors that affect the increase in labor absorption. Therefore, it is necessary to analyze the factors that are thought to affect the increase in labor absorption. This study aims to analyze the factors that influence labor absorption in Central Java Province. This study uses a descriptive quantitative approach with a panel data regression model. The best model selection test used is the Chow test, Hausman test, and Lagrange Multiplier test (LM) Test which was carried out using the Eviews 9 software. This study uses cross section data from 35 districts/cities in Central Java Province and time series data on the number of workers, labor force, unemployment, minimum wages, and GRDP of each district/city for the 2015-2020 period. The results of the discussion show that simultaneously and partially the number of workers, the number of the workforce, the number of unemployed, the minimum wage, and GRDP have an effect on the absorption of labor in Central Java Province.

Abstract

Poverty is a major problem in a country. The Indonesian government has made various efforts to tackle the problem of poverty. The main problem faced in poverty alleviation is the large number of people living below the poverty line. Therefore, this study aims to predict the poverty line in Purbalingga Regency for the next three periods as one of the efforts that can be made by the government in poverty alleviation. The method used in this study is a one-parameter linear double exponential smoothing from Brown. The software used in this research is Zaitun Time Series and Microsoft Excel. The steps taken are determining the forecasting objectives, plotting time series data, determining the appropriate method, determining the optimum parameter value, calculating the single exponential smoothing value, calculating double exponential smoothing value, calculate the smoothing constant value, calculate the trend coefficient value and perform forecasting. Based on the calculation results, the optimum alpha parameter value is 0.7 with MAPE value of 1.67866%, which means that this forecasting model has a very good performance. The forecast value of the poverty line in Purbalingga Regency for 2021 is Rp. 396,516, in 2022 it is Rp. 417,818, and in 2023 it is Rp. 439,120.

Abstract

Director General of the World Health Organization (WHO) Tedros Adhanom Ghebreyesus officially announced the coronavirus (COVID-19) as a pandemic, on March 11, 2020. To prevent the spread of coronavirus in Indonesia a Work From Home (WFH) policy, Large-Scale Social Restrictions (PSBB) was made. , as well as limiting the mobility of people from one area to another. One of them is PT Kereta Api Indonesia which directly reduces the number of long-distance train trips. Because of the dangers of the coronavirus and the issuance of government policies, citizens swiftly comply with the policies that have been issued. Therefore, it is necessary to know whether there is an influence on the passenger volume of the economi class Train (KA) before and after the Covid-19. The method used for known data is the Comparative Hypothesis Test. The decision obtained was that there was an influence on the volume of economi class train passengers before and after the Covid-19.

Abstract

Cauchy-Schwarz inequality is an important property on inner product spaces. This inequality can be generalized to 2-inner product spaces. We can be inducted a norm from those inner product spaces and then generalized that norm to 2-norm. This paper will reprove Cauchy-Schwarz inequality used positive semi definite of Gram matrix such that sub-matrix of Gram determinant is non-negative.

Abstract

We discuss in this paper a weak type (p, p) inequality (where ) for maximal operator on generalized non homogeneous Morrey spaces. Our proof uses the result of Garcia-Cuerva dan Martell (2011).
