Research on Predicting Skilled Labor Availability to Enhance Sustainability Building Practices

The construction industry belongs to a very large industry within a country. Therefore, the construction industry contributes greatly to the national economy and is consistent in providing jobs for many people. There are various problems faced in the construction industry, one of which is the limitation in the provision of certified workers in Indonesia. The problem of the challenges of the construction industry at this time is that the current construction workforce in Indonesia is very lacking in terms of the number of workers, labor certification, and the distribution of certified workers in terms of experts and skilled (SKA & SKT) which in fact is still experiencing inequality if you look at the total workforce currently owned. This study aims to analyze the profile of expert and skilled certified construction workers in 2021, analyze the relationship between the number of construction work and construction absorption that exists at this time, and analyze the projection modeling of expertly and skilled certified construction workers from 2013-2020 in the future. In research objective 3, a research method was carried out using ARIMA (Autoregressive Integrated Moving Average) forecasting analysis. The results of this study obtained forecasting results in each province for expert and skilled certified construction workers for the next 2-4 years starting from 2022-2025. Overall, this research has the potential to improve the competitiveness of Indonesia's construction sector in an era of more sustainable development, while addressing the skills gap issues that exist in the industry today.
