Abstract

This research aims to determine Technical Efficiency Change (TEC), Scale Efficiency Change (SEC), Technological Change (TC), Total Factor Productivity (TFP) in the chemical industry in Indonesia. Using data form large anda medium manufacturing industries in Indonesia, the Stohastic Frontier method is used to determine TEC, SEC, TC, TFP. The results of the average TEC, SEC, TC, TFP show negative changes for productivity in the chemical industry in Indonesia. Based on the research results, the company must provide incentives in the form of subsidies or financial assistance to replace old machines with more efficient technology and maintain the stability of raw material prices.

Abstract

This study analyzes the factors that influence income exploitation among child workers in Indonesia using secondary data from the August 2022 National Labor Force Survey (Sakernas). A quantitative approach and binary logistic regression were applied to test the influence of variables such as regional classification, gender, age, educational status, working hours, and type of work on the likelihood of income exploitation. The results of the analysis show that gender has a significant effect, with female child workers 0.46 times more likely to be exploited than male child workers. Age also has a significant effect, with younger child workers 0.87 times more likely to experience exploitation than older child workers. Child workers who work more than 40 hours per week are 1.65 times more likely to be exploited than those who work ≤ 40 hours per week. In addition, child workers in the informal sector are 2.46 times more likely to be exploited than those in the formal sector. Meanwhile, regional classification and educational status do not have a significant effect on the level of income exploitation of child workers in Indonesia

Abstract

The open unemployment rate in Central Java Province remains a significant issue, despite positive increases in minimum wages, education, and population during the 2020–2024 period. Increases in the minimum wage and average years of schooling have not fully addressed the disparity in job opportunities between regions, resulting in uneven labor distribution across districts or cities.This study analyzes the effect of minimum wages, education, and population on the open unemployment rate in Central Java Province during the period 2020-2024. This study uses panel data with the Fixed Effect Model (FEM) approach and utilizes secondary data from 35 regencies/cities in Central Java. The model estimation results show that the minimum wage, education, and population variables simultaneously have a significant effect on the open unemployment rate in Central Java. Partially, the minimum wage and education variables have a negative and significant effect on the unemployment rate. Meanwhile, the population variable has a positive and insignificant effect on the unemployment rate. The government is expected to pay serious attention to the minimum wage system, improving the quality of education, and the availability of job opportunities.

Abstract

This study analyzes the influence of social factors such as population density and economic factors such as poverty and open poverty levels on crime in ten provinces in Sumatra during the period 2020–2024 using secondary data from the Central Bureau of Statistics (BPS) and the Fixed Effect Model (FEM) panel data regression method. The results show that population density has a positive and significant effect on crime, while poverty and poverty have no significant effect. The implications of this study emphasize the importance of multidimensional policies through population growth management, labor market interventions for at-risk youth, more targeted social protection, community-based law enforcement, and cross-agency data system integration to support inclusive and sustainable development in Sumatra.

Abstract

This study aims to determine the effect of agglomeration economies on technical inefficiency at the firm level of the manufacturing industry in East Java. The data establish from an annual survey of medium and large manufacturing conducted by Statistical Indonesia covering 2010-204. The Stochastic Frontier Analysis method is used to determine the economic agglomeration of technical inefficiency. The results show that specialization has positive influence on technical inefficiency, while Diversion and Firm Size have a negative influence on technical inefficiency of manufacturing industry firms in East Java Province. Although competition does not influence technical inefficiency. Therefore, the government should consider the externalities of agglomeration including specialization, diversity, and competition, that provide significant advantages to manufacturing companies in East Java. Nevertheless, while these agglomeration benefits contribute to economic growth, they often do not correspond to the actual environmental conditions.
