Abstract

Development of cajuput plantation currently becomes the most important activity in KPH Bojonegoro since it provides an essential contribution to maintain the future viability of company. However,the growth performance of cajuput stand relatively varies one of which is influenced by planting design. This study aims to determine the optimum planting design for supporting cajuput stand development. It was conducted by evaluating two different planting designs that generally used for cajuput establishment, namely C1 (spacing 3 m x 1 m) and C2 (spacing 5 m x 1.5 m x 1.5 m). Five parameters were used to evaluate the growth performance and oil production of cajuput stand for each planting design, i.e., survival rate, quadratic mean diameter, basal area, harvesting biomass, and cajuput oil production. Data were collected by field measurementusing a sampling plot 50 m x 50 m with six replications for each planting design. Comparisonmean of cajuput growth performance between two planting designs were analyzed separately for each parameterusing t-test. Results documented there were not a significant different for all parameters, except survival rate. The planting design C2 generated higher survival rate (94.9%) than planting design C1 (64.7%).The planting design C2 was recommended for cajuput development in KPH Bojonegoro. Besides requiring the lower planting density, the use of planting design C2 can optimize land utility with a similar productivity to planting design C1.

Abstract

Forest rehabilitation of Timor Island's dryland ecosystems using eucalyptus plants plays an important role in improving land cover but also in mitigating climate change and providing an alternative renewable energy source. The aim of this study is to explore the enormous energy storage potential of eucalyptus plants for commercial purposes using a high spatial resolution remote sensing approach. The Pléiades satellite imagery acquired on 10/09/2021 covering ca. 27 ha study area managed by Timor Tengah Selatan Forest Management Unit was used to identify the density of eucalyptus plants using Normalized Difference Vegetation Index (NDVI) values greater than 0.699. The density of eucalyptus plants is classified into low, moderate, and high tree density with NDVI values greater than 0.699 to 0.765, greater than 0.765 to 0.833, and greater than 0.833 to 0.901, respectively. The total potential energy production of the study area was estimated using a combination of assumed eucalyptus tree density, the calculated area of each density, and the average energy storage of individual trees. The results showed that the density of eucalyptus trees was classified as low, moderate, and high, with coverage areas of 6.8 ha, 12.9 ha, and 3.0 ha, respectively. The potential energy production of low, moderate, and high density approaches 1,103,432.33 MJ; 5,522,999.19 MJ; and 2,120,715.04 MJ, respectively, with a total estimated energy storage of 8,747,146.57 MJ. This obtained number of potential energy estimations indicates that forest rehabilitation of dryland ecosystems through eucalyptus plantations has a promising future as an alternative renewable energy source.

Abstract

Carbon dioxide (CO2) is the main greenhouse gas, and its atmospheric concentration continues to increase. Globally, in 2019, the average CO2 at Earth’s surface reached 409.8 ppm. Information on carbon storage remains a strategic issue for sustainable forest management and climate change mitigation. Sibolangit Nature Tourism Park is a 24.85 ha conservation area with high biodiversity and a range of potential environmental services. This study aims to quantify the aboveground biomass, carbon stock, and CO2-equivalent emissions in the Sibolangit Nature Tourism Park. The study used 5% intensity sampling, resulting in 31 plots selected using simple random sampling. The plot size was 400 m2 (trees), 100 m2 (poles), 25 m2 (saplings), and 4 m2 (seedlings). The vegetation species, height and diameter at breast height were recorded to measure the biomass of trees, poles, and saplings. The aboveground biomass of vegetation was estimated using a non-destructive method with Chave’s allometric equation, while the biomass of seedlings was calculated using a destructive method according to SNI 7724-2019. The carbon stock was measured by multiplying the biomass by 0.47. The carbon stock value was then converted to CO2-equivalent using a conversion factor of 3.67. The results showed that Sibolangit Nature Tourism Park had an aboveground biomass of 525.73 t/ha, a carbon stock of 247.09 t C/ha, and a total carbon stock of 6140.30 t C, equivalent to 906.84 t CO2/ha. The study site had potential as an atmospheric CO2 absorber, indicating its primary role in climate change mitigation and in the FoLU Net Sink 2030 program.
