Abstract

Deforestation 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

Abstract

The mangrove ecosystem is one of the many ecosystems found along tropical beaches that have a function as a buffer area between land and sea and produce organic matter. There are several factors that influence the spread of mangrove plants, namely the physical factor of the soil. This study aimed to determine the soil carbon content in the mangrove ecosystem in the village of Temmalebba, South Sulawesi. The data collected in the form of bulk density (BD), organic matter (BO) and percent C for analysis of carbon content was obtained from the analysis of soil samples taken from 10 points with 3 replications for composite samples. The sampling point was determined based on the growth and density of mangroves. Furthermore, the data was analyzed using the organic C equation and carbon content. The results showed that the highest bulk density was found at a depth of 60–100 cm with a value of 1.28 g/cm3. The highest percent of organic matter content found at a depth of 0-30 cm with a value of 9.18%. The highest soil carbon content found at a depth of 60–100 cm with a value of 225.38 (MgC ha-1). Soil carbon content in the mangrove ecosystem of Bone Bay, Temmalebba village is strongly influenced by several factors, including soil depth, bulk density, organic matter, and soil texture.

Abstract

Information regarding the potential and dominance of local plant species in the Sassa Village Protection Forest, North Luwu Regency is still limited. In fact, there are fewer and fewer local plant species that are used by the community, this is indicated by the difficulty of obtaining local plant seed sources. This difficulty is due to the lack of local parent plants in this area, for this reason it is necessary to study the potential of local plants and the selection of parent trees for local plant seed sources. The research method by collecting data was carried out using exploratory techniques with the transect method, then the parent tree that had been determined as a seed source stand that had met the criteria as a parent tree was given a coordinate point. Then the scoring was carried out on tree height (T), tree diameter (D), branch-free height (Tbc), trunk straightness (KB), trunk surface (PB) and tree health condition (KK). The results of this study obtained 16 types of plants with the highest T score of 20, 16 species of plants with the highest D score of 30, 33 species that had the highest Tbc score of 15, and 3 types of plants that had the highest KB+PB+KK score of 20. There were 18 species with a total score of 60 that met the highest criteria as well as from the various genotypic characteristics that had been observed.

Abstract

In 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.

Abstract

Aren (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.

Abstract

Wildlife trade for consumption needs is found in various regions in Indonesia, one of which is in North Sulawesi Province. This animal trade spreads in traditional markets, including the Beriman Market in Tomohon which is also a domestic and foreign tourist destination, Langowan and Kawangkoan Markets in Kab. Minahasa. Karombassan and Bersehati Market in Manado City. Even the trade in wild animal meat has now entered modern markets in Manado City, which is the capital of North Sulawesi Province. This development of course threatens the preservation of biodiversity, especially endemic species. This study aims to determine the types of wildlife traded in North Sulawesi both in traditional and modern markets, to compare the price of wild animal meat in traditional and modern markets in North Sulawesi, and to determine the conservation status of traded wildlife species. There are 8 types of wild animals traded in traditional markets and 5 species in modern markets. The price of wild animal meat in the modern market is higher than in the traditional market. There was one endemic species that was traded, and 2 species that were listed in Appendix II of CITES.

Abstract

The 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 pattern

Abstract

Tapping 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%).
