The Asian tapir is a primitive mammal whose habitat is heavily fragmented due to human activities. Studies on the Asian tapirs in Sumatra are very few, thereby basic information for developing tapir conservation programmes is limited. This study aimed to develop the species distribution model to map the potential distribution of tapirs in Batang Gadis National Park (BGNP), investigate the characteristic of tapir habitat, and identify tapir feed plants around BGNP. The model was developed using the Maximum Entropy (Maxent) approach, based on the existing information on tapir occurrence in BGNP and environmental variables. Vegetation characteristics in different land cover (primary forests, secondary forests, and open fields) were investigated using the strip transect method. This study found that zonal classification, temperature and precipitation have the greatest percentage contribution to the model. The model estimated that around 24.45% of BGNP areas are suitable for tapir habitat, and tapirs distribute near community gardens. Our results also showed that plant diversity at study sites was categorised as moderate-high. About 23 plant species dominated by the Moraceae family were identified as feed plants for tapirs. In developing tapir conservation programmes, BGNP management needs to consider tapir distribution that is closed to community gardens. We propose BGNP to enrich feed plants in open fields of the wilderness and traditional zones; reduce the canopy cover in the wilderness and utilisation zones to stimulate the growth of feed plants; facilitate local people to live harmoniously with tapirs; involve local communities in tapir conservation programmes; encourage local communities to plant non-palatable crops for tapirs; and provide a compensation scheme.

Abstract. Lestari KG, Budi SW, Suryaningtyas DT, Yudhiman E. 2022. Vegetation development in post-gold mining revegetation area in Minahasa, North Sulawesi, Indonesia. Biodiversitas 23: 3224-3233. Gold mining activities in Indonesia, in many areas, have a negative impact on the environment. Activities that can improve the quality of post-mining land include revegetation activities, which are included in post-mining land reclamation activities. The purpose of this study was to analyze the development of vegetation in post-gold mining revegetation areas. Vegetation data were collected using the plotted line method (natural forest) and the Systematic Sampling method with Random Start (revegetation area). The analysis found that the vegetation structure in the post-gold mining revegetation area aged 3 to 10 years has complete vegetation levels (saplings, saplings, poles, and trees). Compared to natural forest, which only includes 30 tree species and 7 herbaceous, this revegetation region has a greater diversity of species, with 66 tree species and 16 herbaceous. The longer the age of revegetation is not followed by an increase in species and an increase in the value of the species diversity index. However, it is still better than the revegetation at a young age and is closer to the condition of a natural forest. The revegetation area aged 8 and 7 years has a higher number of species than natural forests and other revegetation areas.

“…This study aimed 1) Analyzing the difference in the wood pellet quality obtained from distinguished types of raw materials and ages; 2) Evaluating the relationship between raw material and wood pellet parameters. Out of the 25 cultivated and natural types of woody plants in South Sumatra, Indonesia, it was found that Enterolobium cyclocarpum, Cassia siamea, and Acacia mangium had the highest dominance value (Yuningsih et al, 2021). This was derived from land revegetation activities, and met the SNI quality standards for all required parameters, including water and ash contents, volatile matter, fixed carbon, compressive strength, and calorific value.…”

It needs to become a source of renewable energy raw materials derived from biomass, through revegetation reclamation activities. Therefore, this study aims to analyze the differences in the quality of the wood pellets derived from distinguished raw materials and ages. It also aims to evaluate the relationship between raw material and wood pellet parameters. In this process, the method used emphasized the measurements of the chemical-physical and quality parameters of the materials and pellets, respectively. These analyses were subsequently carried out through a comparative test with the quality standards of SNI (Indonesian National Standard) 8021-2014 and SNI 01-6235-2000. To analyze the relationship between raw material and wood pellet quality parameters, a statistical test of Pearson correlation (product-moment) was conducted. Based on the results, the pellets produced from post-mining land revegetation reached SNI quality limits on the parameters of water content, density, fixed carbon, and heat. This proved that all the chemical-physical features of the raw materials had a relationship in improving the quality of wood pellets. Regarding the comparison between types, the Acacia mangium pellets relatively had the best quality.
