Relation of Soil Physical Parameters and Dominant Vegetation with Infiltration Capacity in Latuppa Sub-Watershed Palopo Indonesia
Get PDFThe inflitration capacity is the soil’s ability to accommodate water that seeps into the soil, reducing surface runoff that will cause flooding, such as in the downstream area of Palopo city. This study aimed to determine the influence of dominant vegetation and soil physical characteristics on infiltration in the upstream area of the Latuppa Sub-Das, Mungkajang District, Palopo city. Data collection was carried out by direct observation in the [email protected] field in a purposive manner in 10 plots, which represent the condition of vegetation in the upstream area of the Latuppa watershed, and each plot consisted of 3 replications to observe infiltration and soil samples. The data were analyzed via the rational method, the Horton method, and vegetation index analysis. Additionally, the data were analyzed via simple linear regression and multiple regression analysis to determine the influence of the dominant vegetation and physical characteristics of the soil on the infiltration capacity. The highest infiltration capacity was found in plot 10, with an infiltration capacity of 107.5 mm/minute (6,450 mm/hour) and an average infiltration rate of 0.4 mm/minute (24 mm/hour). The dominant vegetation cover is Cananga odorata, with a vegetation index value of 78.41%. Plot 10 has a height of 362.79 masl, a gentle slope, a crumbly soil structure, a clay sand texture, a very high soil density and 2.10% organic matter. Based on observations and data analysis, the factors that influence the infiltration capacity in the upstream area of the Latuppa subwatershed are vegetation conditions, altitude, slope and physical properties of the soil
POLA SEBARAN SPASIAL BIOMASSA DI AREAL REVEGETASI BEKAS TAMBANG NIKEL
Get PDFThe aim of this study was to identify the spatial pattern of biomass distribution in the revegetation of the post-mining area in PTVI. The nearest neighbour analysis method by comparing the distance of an individual was used to determine the spatial biomass distribution pattern in the post nickel mining revegetation area of PTVI. The nearest neighbour analysis was used to explain the distribution pattern of locations using a calculation that considers the distance, number of locations and acreage. This analysis produced a final result in the form of an index ranging from 0 until more than 1. It can be explained as NNI <1, clustered spatial pattern, NNI = 1, random spatial pattern and NNI> 1 dispersed spatial pattern. This research was found that there are clustered (K1, K2, K3) and dispersed patterns (K4) of biomass spatial distribution patterns in PTVI’s post nickel mining revegetation area.Keywords: post-mining, revegetation, biomass, spatial distribution patter

Biomass Estimation Model in Revegetation Area of Nickel Post-Mining
Get PDFDeforestation and forest degradation are one of the most crucial issues in the forestry sector. The impact of deforestation and forest degradation due to the opening of forest areas for mining activities that causes damage to sustainable forest ecology. This condition requires companies as miners to carry out revegetation activities in post-mining areas to restore forest existence. PT. Vale of Indonesia (PTVI) is a nickel mining company located in Sorowako, South Sulawesi Province, which has carried out revegetation activities and is considered quite successful. This assessment has not included biomass as an indicator of forest productivity. Biomass is one of the determinants of forest productivity in post-mining areas needs to be further investigated to maximized revegation management. The objective of this study was to measure and construct a model for estimating biomass in the revegetation of the post-mining area in PTVI. The results of this study obtained a regression model of the rank as a biomass estimator in the revegetation of the post-mining area in PTVI. The form of the selected model equation is Y= 2,59505E-13 X1 2,489 X2 3,645. The independent variable is X1 = DVI (vegetation index) and X2 = C% (percentage of canopy). The regression model chosen has a determination coefficient of 70,60% and a standard deviation of -0,33528. Keywords: biomass, post-mining, regression model, revegetation </p
PENGARUH KOMPOSISI ASAM SULFAT (Hâ‚‚SOâ‚„) SEBAGAI STIMULANSIA PADA BERBAGAI DIAMETER DALAM MENINGKATKAN PRODUKTIVITAS GETAH PINUS
Get PDFTapping pine sap at PT Inhutani I using the quarre method and giving stimulants in the form of sulfuric acid concentration (Hâ‚‚SOâ‚„) was carried out to increase the productivity of pine resin. The purpose of this study was to determine the composition of sulfuric acid (Hâ‚‚SOâ‚„) as a stimulant at various diameters on the productivity of pine resin, with a ratio of 10%, 20%, and 30% sulfuric acid composition used. The study results obtained latex productivity data for 30 days, with the highest average being at a concentration of 20% (K2) with a diameter of 60 cm (D1) with a value of 33.66 g. In contrast, the lowest productivity was found at a concentration of 0% (K0) with a diameter of 60 cm (D1) of 4.66 g. Analysis of variance showed that the concentration treatment had a significant effect on the productivity of pine resin, with an F-count value of 4.02 > an F-table value of 3.01 at the 5% level. The results of the Tukey test showed that the stimulant concentration of K2 (20%) had a significantly different productivity effect from stimulants and the concentrations of K1 (10%) and K3 (30%)
Assessment of Carbon Storage Potential and Economic Value in Green Open Space Vegetation of Palopo City
Get PDFGreen open space (RTH) plays an essential role in climate change mitigation through its capacity to absorb and store carbon. Palopo City, which has experienced rapid urban growth, requires scientific data on carbon storage potential in its green open spaces. This study aimed to analyze carbon storage potential and the economic value of carbon in RTH vegetation in Palopo City. The research was conducted in selected RTH areas across nine districts using a non-destructive sampling method and allometric equations. Vegetation biomass was estimated from tree diameter measurements and converted into carbon storage and CO₂ absorption. Carbon economic value was calculated using carbon pricing estimates of USD 5–10 per ton. The results showed that total carbon storage in Palopo City’s RTH reached 9,094.93 tons/ha, with the highest value found in the Salubulo Islamic Cemetery RTH, North Wara District. This location also exhibited the highest carbon economic value. These findings highlight the strategic role of urban green open spaces in climate change mitigation and sustainable urban development)

Get PDFAren (Arenga pinnata) is a type of palm where almost all of its parts can be utilized, starting from the roots, stems, leaves, flowers, and fruit. Based on the growth rate of sugar palm can show the pattern of distribution using the Morisita index formula. The distribution pattern is a series that has settled on a symptom itself between individuals, which can be divided into three, namely uniform (regular), random (random), and clustered (clustered). This study aims to determine the distribution pattern of the sugar palm (Arenga pinnata) population based on the growth rate. This research was carried out in Sangtandung Village in July 2021. The data collection method used a purposive sampling technique by placing plots in an area with a sugar palm population following the river body 200 meters long. The distribution pattern of sugar palm based on the growth rate was analyzed using the Morisita index formula. Based on the Morishita index, the study results obtained a pattern of palm sugar distribution based on the growth rate, namely seedlings, saplings, trees with clustered patterns, and poles with uniform patterns

Get PDFIn an effort to realize the concept of sustainable forest management, it is necessary to involve the community around the forest as the main actors who often interact with the forest. In this case, the concept in question is the concept of community participation. This study aims to determine the participation of forest communities in the existence of community forests. This research was conducted in Battang Village, West Wara District, Palopo City, South Sulawesi Province. Data was obtained directly through surveys and direct field observations, data collected through the observation method and semi-structured interviews were processed and clarified according to the research objectives and then analyzed using qualitative data analysis. The results obtained by community participation in community forestry are the lack of community participation which initially numbered 137 people, only 35 people left who were active due to contradictory plans and conditions in the field that triggered problems in the group
