Abstract

Post-mining land rehabilitation is an important strategy to mitigate climate change and conserve tropical ecosystems. Surface mining activities in East Kalimantan have caused ecological degradation and the release of carbon stored in vegetation and soils. Revegetation has been widely practiced as the main approach to restore ecosystem functions, including initial carbon accumulation by understory plants. This study aims to estimate the carbon stock of the understory on post-mining land that has undergone revegetation for one year at the PT Insani Baraperkasa site in Loa Janan, East Kalimantan. The method used was destructive sampling of understory biomass from 10 plots measuring 5 m x 5 m, each with subplots measuring 0.5 m x 0.5 m. Biomass samples were dried and converted to carbon. The results showed an average carbon stock of 1.26 tons/ha. These results suggest that understorey vegetation plays an important role in early stage carbon recovery on post-mining land. Understory carbon monitoring can be an effective early indicator to measure the success of ecosystem restoration. Keywords: revegetation, understorey, post-mining, carbon

Abstract

The palm oil industry is currently the main supporting sector of the economy from the plantation sector with the main product being Crude Palm Oil (CPO). East Kalimantan is one of the provinces as the center of palm oil production in Indonesia. This study aims to determine the factors that affect East Kalimantan CPO exports with the Ordinary Least Square (OLS) method approach. The variables included are East Kalimantan CPO Exports (Y), East Kalimantan Palm Oil Production (X1), East Kalimantan Total Exports (X2), and East Kalimantan GRDP (X3). The results of the analysis show that the model used is free from classical assumptions so that it can be interpreted. The F-test results show that the variables of palm oil production, total exports, and GRDP together have a significant effect on East Kalimantan CPO exports. The t-test also shows that the variables of palm oil production, total exports, and GRDP each have an effect on East Kalimantan CPO exports. The variables of East Kalimantan palm oil production (X1) and East Kalimantan total exports (X2) have a positive and significant effect on total East Kalimantan CPO exports, while East Kalimantan GRDP (X3) has a negative and significant effect on total East Kalimantan CPO exports. Keywords: CPO, Export, East Kalimantan, Palm Oil
