Abstract

Post-mining land revegetation is one of PT. ANTAM UBPE Pongkor committed to restoring the impact of both mining and non-mining activities in its concession area, comprising 3 locations (GHSNP Critical Land, Cepu Landslide Block, and Mount Puntang Block). This study aimed to identify the species composition, diversity, evenness, and richness of tree species. This research was carried out by observation at 12 locations following checkered paths, parallel to intersecting contour lines. Observation sample plots for the tree, pole, sapling, and seedling were measured on areas 20x20 m, 10x10 m, 5x5 m, and 2x2 m, respectively, with maximum sampling intensity of 10%. Vegetation composition and structure were observed by measuring the Importance Value Index (IVI), the Biodiversity Index (H'), Species Evenness Index, and Richness Index (Dmg). Sixty species of trees were found in the IUP area of PT. ANTAM UBPE Pongkor, in the growth phase of trees, saplings, poles, and seedlings, dominated by Puspa, Rasamala, Waru Lot Mara, Calik Angin, Huru, Kaliandra, and Ganitri, which were spread almost evenly in each location, with IVI value of 50% -300 %. Species diversity with a high category (H' =3.23) was found in the natural forest in the Baching Plant, the medium category was in the cepu landslide block reclamation area (2.67), while the small diversity was in the reclamation area around the administration office (1.61). The evenness index (E) ranged from 0 to 1, and the species richness index (Dmg) ranged from 0 – 7.58, indicating that the IUP area is quite diverse regarding its biodiversity.

Abstract

Forests have different species and structure compositions depending on local conditions. One of the forests that has a specific character is Peat Forest. The condition of the peat forest footprint explicitly influences the types of flora and fauna that can adapt to the condition of the forest. When there is a disturbance to the peat forest ecosystem, it is necessary to know how the effort is to reverse the condition of the forest ecosystem. Efforts can be made to restore the condition of the ecosystem by restoring the ecosystem. This study aimed to determine the composition, INP, diversity index, and stratification of peat forests in the Riau ecosystem restoration area in Pelalawan District. Data collection methods were carried out with vegetation analysis, field observations, and literature studies. The results of this study indicate that there are 11 species found in the Young Shrub land cover, with the dominant is Ficus carica L, in the Old Shrub land cover found 28 species with the dominating is Shorea sp, while in the Secondary Forest land cover found 55 species, with the type what dominates is the Syzygium sp. The species diversity index in the Young Shrub land cover is of low value, while the Old Shrub and Secondary Forest is of medium value. Based on field observations, canopy closure conditions in the study sites consisted of strata A, B, C, D, and E, which were dominated by Stratum C (4-20 m).

Abstract

The Sumatran orangutan (Pongo abelii) is an arboreal primate that spends all its daily activities in the trees. Nest-making activities are carried out daily, selecting trees with certain characteristics to make nests. Much research has been done on the character of orangutan nest trees. However, there needs to be more information about the character of orangutan nest trees at the Suaq Belimbing Research Institute, Gunung Leuser National Park. It is known that Suaq Belimbing is a peat swamp forest ecosystem in Gunung Leuser National Park, precisely in Kluet, South Aceh, with quite diverse vegetation composition. Even so, not all vegetation is used as orangutan nest trees. This study aims to obtain data on the characteristics of orangutan nest trees in the Suaq Belimbing peat swamp forest habitat of Gunung Leuser National Park. Data was collected for three months using the line transect method. The results of the study obtained 65 individual trees used as orangutan nests. 45.15% of the nest tree characters had a height of 11-20 m, and 24.46% had a trunk diameter of 31-40 cm. The most widely used crown shape for making nests was cylindrical.

Abstract

The problem of the Citarum Hilir watershad is dominated by the low awareness of the community and local government for natural preservation. Therefore it is necessary to conduct a perception assessment to support the success of activities in the preservation of the Citarum Hilir watershad. This study aims to describe people's perceptions of sub-watershed management and their functions. The sampling method is a purposive sampling technique. The data collection method was carried out by in-depth interviews with 30 respondents. Data analysis was carried out using a Likert Scale and described in the form of the percentage (%) with the highest number of answers. The results showed that the public's perception of the watershed was included in the category of quite understanding and very understanding (50%) that the watershed is a stream that surrounds and merges with the river and its tributaries. The community's perception of the condition of the watershed is in the category of very understanding (57%) that the condition of the watershed often experiences inundation in several parts of the downstream of the village and a lot of waste. The community's perception of the impact of watershed damage is included in the very understanding category (100%). The community's perception of the utilization of watershed resources is included in the category of very understanding (70%). In the category of very understanding (63%) of using the watershed as a means of transportation, irrigation of rice fields and daily needs. The public's perception of the watershed profile is in the understanding category with a score of 4.0.

Abstract

High Conservation Values ​​(HCV) are important social and environmental values ​​in ecosystems and landscapes that are jointly identified by long-term multi-stakeholder processes as important values ​​that must be conserved in the management of natural systems. The variety of forest ecosystem services that can be utilized makes the people of the Moisigin District, Sorong Regency, West Papua Province dependent on the forest for their daily lives. The research was conducted in three villages in the Moisigin District, namely Klasof, Klafdalim and Ninjimor villages. The aim of the study was to identify the conservation value in the socio-economic aspects of culture and to determine the level of community dependence on forest areas in the Moisigin District, Sorong Regency, West Papua Province. This study used a survey research method, determined the respondents by Proportional Random Sampling, with the number of respondents was 81 people, and analyzed descriptively. The results showed that forest areas in the Moisigen District, namely Klasof village and Klafdalim village had HCV 5 in the form of the Klasof water reservoir, the border the Modan river and the Tadalim riverbank, while Ninjimor village has HCV in the form of the Masinau Marga sago plantation and HCV 6 in the form of the Matawol sacred forest. The level of community dependence on the forest area of ​​Klasof village is 38%, Klafdalim village is 29.7% and Ninjimor village is 45% or is included in the Forest Dependent category.
