Abstract

PT Hutan Mulya is one of the companies engaged in natural forest management, carrying out logging activities that cause changes in the value of species diversity in the remaining stands (LoA). There are 651 individuals of 87 plant species in the LoA area (2016 and 2016) and 63 plant species in virgin forest areas, so there are a total of 32 plant groups. The highest Importance Value Index is found in Meranti Merah (Shorea leprosula Miq) and Suhi (Shorea atrinervosa Symington) in virgin forest areas, while in the LoA area it is dominated by the Jambuan (Syzygium Gaertn) species because it is a source of animal feed and is not produced by companies. The diversity index of tree species, poles, and saplings in virgin forest is high (>3.00), whereas in the LoA area (2016 and 2022), the level of trees is high (>3.00), the level of poles is medium (1.00–3, 00), and the level of saplings for LoA 2022 is low (1.00<). Meanwhile, the virgin forest similarity index and LoA (2016 and 2022) are in the same or medium category, between 0.31 and 1.00.

Abstract

This study aims to determine how much carbon stock is stored in logged-over areas by comparing carbon stock in virgin forests. Calculate potential biomass, carbon, carbon dioxide uptake, and economic value of CO2eq uptake in the Logged area of PT Hutan Mulya using purposive sampling data collection techniques for each plot and non-destructive methods through allometric equations. The highest carbon stock potential is in the tree-level diameter class and the location with the highest carbon stock is in the virgin forest area. Meanwhile, the logged area based on the company's establishment from 2011–2022 covering an area of 14,583 ha has a carbon stock potential of 772,537 tons C to the carbon dioxide storage value of 2,835,210.57 tons CO2eq. Based on the assumed price of USD 4.5, the potential economic value of carbon obtained by the government through carbon sales tax is IDR 85,056,317,100. The net profit obtained by the company is IDR 109,494,570,499.42. In contrast, the potential net economic value of the carbon business project scenario results in a combined logged area and virgin forest area of IDR 160,960,838,842.31 for the company and IDR 125,035,753,500 for the government.
