Abstract

Forest as a gift and the mandate of Almighty God bestowed upon the people of Indonesia is a priceless natural wealth; therefore, it must be grateful. His gift is a mandate, therefore, forests must be managed and utilized wisely as a manifestation of gratitude to Allah SWT. Production forest in the KPH areas DampelasTinombo which is in ParisanAgung Village, Dampelas Sub-District indicates that about 410 hectares are in damage, therefore,  it is needed a study about the composition and the potential production forest in Parisanvillage forplanning utilization and plantation forest development which aims at providing welfare for the people who live around the forest area without changing its main function. This research was conducted for 3 months starting from September to November 2015. This research is located at production forest area in the territory of KPHDampelasTinombo which is still territory of ParisanAgung village, Dampelas Sub-district, Donggala, Central Sulawesi. The composition of productional vegetation forest in ParisanAgung Village are 28 vegetation types. The tree level vegetation in the plot is 165 individuals of 25 species of vegetation, the poles vegetation is 140 individuals of 25 species of vegetation, sapling level is 146 individuals of 28 species of vegetation and seedling is 154 individuals of 28 species of vegetation. The potential volume of trees that were in observation plot is 162.53 m3 of 165 individuals, mompi species have the highest volume with 13.17 m3 and the volume level of the pole inside the observation plot is 17.89 m3 of 140 individuals, perupuk kind has the highest volume with 1.63 m3.

Abstract

This study is quantitative research employing survey techniques and spatial modeling. In the research area, particularly in forested areas, the NDVI values range from 0.25 to 0.55 with LST values of 29°C to 37°C. Cooler temperatures below 34°C were observed in the southwest (outside the mining area). The LST values indicate high temperatures above 37°C in the coal mining area, with effects extending up to 6 km. The linear regression equation between NDVI and LST in the coal mining area, with a regression equation of y = -20.888x + 40.458; R^2 = 0.83; r = -0.91, shows an inverse relationship between NDVI increase and ground surface temperature, indicating a good model fit with the data and a strong negative linear relationship between the two variables. The Urban Heat Island (UHI) effect in the mining area, especially at the mining center, shows a UHI with a temperature difference of more than 0.6 degrees Celsius compared to the cooler surrounding area. At the center of the coal mining area, the TVDI value is 0.6-0.8 (high-very high), but in the eastern part of the mine in forested areas with a certain soil type, the TVDI value is 0.2-0.6 (moderately dry - dry), while in other parts of the forested area with a different soil type, the NDVI value is 0.2 (moist). There is a difference in response to different soil types. Drought increases in the forested areas around the mining site, affecting ecosystem productivity and soil moisture.

Abstract

The biophysical model of Mount Babaris aims to predict carbon potential using remote sensing technology to address high levels of greenhouse gases, particularly CO2. This study combines satellite data with field measurements to create a validated model analyzing Forest Canopy Height (FCH), Normalized Difference Vegetation Index (NDVI), Vegetation Density (VD), and Land Surface Temperature (LST). A multiple regression analysis shows a strong correlation between these parameters and VD, with an R² value of 0.8673, indicating that 86.73% of the variation in vegetation density can be explained by these variables. Field validation, including drone photographs, crown and stem base density measurements, and plant size, ensures the accuracy of the satellite-derived data. The model uses the equation VD = 123.295486 x NDVI - 0.413961 x LST - 0.410253 x FCH - 3.173195, validated through field data. For processing field measurements, the equation LBDstemCor = 0.007645 x LBDcrown + 0.034348 x VD - 1.575439, with an R² value of 0.9564, further demonstrates its accuracy. To estimate carbon potential in kilograms per pixel (CPP), the equation CPP = LBDstemCor x FCHcor x 0.7 x 680 x 1.34 x 0.47 was used. The predicted carbon potential for Mount Babaris (1,576 ha) ranges from 607,767.55 to 607,829.54 tons, reflecting the model's precision in estimating carbon storage. This model plays a crucial role in monitoring and predicting carbon potential, supporting environmental management and climate change mitigation efforts. By integrating GIS and remote sensing, the model offers a scalable, replicable methodology adaptable to other regions with similar characteristics. It enhances the accuracy of carbon stock estimations and provides essential data for developing strategies to increase carbon sequestration, contributing to global climate change mitigation. The combination of satellite data, field measurements, and statistical analysis makes this model an invaluable tool for effective ecosystem conservation and restoration.
