Open-pit coal mining causes environmental degradation, disrupting ecosystem functions and reducing soil quality. This study evaluated the contribution of vegetation stratification and the Soil Quality Index (SQI) in supporting the recovery of post-coal mining land. The research was conducted on revegetated sites of varying ages (2006-2022) within the PT Allied Indo Coal Jaya mining area in Sawahlunto, West Sumatra. Vegetation structure was analyzed based on five vertical strata: trees, poles, saplings, seedlings, and understory. Concurrently, soil quality was assessed using the SQI, which incorporates physical, chemical, and biological soil parameters. They showed that revegetated sites older than 10 years exhibited more complex vegetation structures and significantly higher SQI values. Among the strata, understory frequency showed the strongest correlation with SQI (r = 0.907), followed by tree density (r = 0.530), reflecting the crucial role of these two layers in enhancing organic matter, microbial activity, and soil stability. Principal Component Analysis (PCA) identified soil pH, organic carbon, total nitrogen, microbial biomass, and soil permeability as the key indicators contributing to SQI formation. These findings confirm that the interaction between vegetation stratification and soil quality plays a central role in accelerating ecosystem recovery and supporting the long-term sustainability of post-mining land revegetation.

Drought stress in crop occurs due to imbalance between water supply and demand. Crop responses to drought stress depend on their ecotypes. This study was aimed at examining the tolerance of the physic nut ecotype to drought stress in inceptisol. This study was conducted at Silviculture greenhouse, Forestry Faculty IPB, from September to December 2007. A Completely Randomized Design with two factors was used in the experiment, i.e. water content (80, 60, and 40 % of field capacity) and physic nut ecotypes (Palu, NTB, IP-A, and IP-P) The results showed that (1) drought reduced stem diameter (31.4%), root length (65.49%) and leaf area (72.73%), and decreased plant dry weight (74.83%),(2) tolerance level of the evaluated physic nuts on the drought stress were moderate tolerance (IP-1A, NTB, Palu) and sensitive (IP- Pakuwon). Key words: physic nut, drought stress, tolerance

Cardamom (Amomum cardamomum), the ‘Queen of spices’, is a native Indonesian spice, a type of potential biopharmaceutical currently prospective because of its high selling value, especially for its fruit, with various benefits and its wide use. So far, cardamom essential oil comes from the utilization of its fruit, but the production is more limited, unlike the sustainably produced leaves, therefore, its leaves have the potential to be developed. This study aims to analyze the essential oil yield and 1.8-cineol content of cardamom leaves essential oil (CLEO) grown in agroforestry systems. The CLEO was obtained by steam-water distillation, while the 1.8-cineol content was analyzed by gas chromatography–mass spectrometry (GC-MS). The experimental design employed was a Randomized Complete Block Design with three cropping patterns as a treatment and three doses of bokashi fertilizer as blocks. The results showed that the highest yield of CLEO was generated in the sengon + cardamom agroforestry pattern of 3.16%, and the highest content of 1,8-cineol in CLEO was generated in the sengon + cardamom + arrowroot agroforestry pattern of 47.23%, while the lowest yield of CLEO and the 1,8-cineol content were found in the monoculture pattern of 2,02% and 43.16% respectively. Agroforestry practices have the potential to increase 1,8-cineol content and the yield of essential oil in cardamom leaf, which will be prospective in forest management to support forestry multi-business and social forestry programs.

For effective teak plantation management, early detection system in controlling teak mistletoe requires various basic information, including degree of infestation and accuracy of the species names. Mistletoe infestations in teak and mistletoe species name have been reported, but there are still problems in identifying the correct species or subspecies due to morphological similarity. The objective of this study was to clarify the species identity of hemi-parasitic mistletoe plants, which were found in teak Clonal Seed Orchard (CSO) in Padangan, East Java Province, Indonesia using DNA barcodes. Species identification of teak mistletoe based on leaf morphological characteristics and universal DNA barcode regions (i.e. matK and rbcL) were carried out. The results showed that the Canonical Discriminant Analysis (CDA) could differentiate Dendrophthoe pentandra and Macrosolen tetragonus based on leaf morphological characteristics. Variables having high correlation to distinguish both species were length of petiole, width of the widest leaf, number of secondary leaf veins, leaf base shape, aspect ratio, form factor and perimeter ratio of diameter. The results of DNA barcoding showed that the two DNA barcode regions presented good amplification and sequence results. Both DNA barcode regions successfully differentiated two species i.e. D. pentandra and M. tetragonus which belong to Loranthaceae family and have similar leaf morphological characteristics. Those regions were also able to identify Viscum articulatum and other species belonging to Santalaceae family. These results suggested that the two DNA regions could become recommended universal DNA barcode for identifying teak mistletoe.

Information on metal adaptation in plants is essential to understand the mechanism of heavy metal remediation, including lead (Pb), mediated by forest plants in contaminated land. This study aimed to identify the adaptation mechanism of jabon (Anthocephalus cadamba Roxb.) seedlings to excessive lead levels based on the tolerance index of growth performance and lead transport to plant tissue. The seedlings were exposed to lead Pb(NO₃)₂ at concentrations of 0, 0.5, 1, 1.5, 5, and 10 mM in nutrient culture for 15 days. The results showed that the tolerance index (TI) of the seedlings significantly decreased with Pb exposure up to 1.5 mM, although the TI values remained above 75%. All seedlings died at Pb concentrations of 5 mM and above. Lead accumulated in all parts of the seedlings, with the highest concentration found in the leaves (735.9 ppm) under 0.5 mM Pb exposure. Pb was transported to the upper portion of the seedlings, as indicated by a transport factor (TF) greater than 1. The results suggest that jabon can tolerate excessive Pb exposure up to 1.5 mM and has potential as a phytoremediator plant.

Mistletoes are hemiparasitic macroparasite plants that interfere with trees and other wild plants in nutrient acquisition. As the plant has low leaf water potential, it draws water from teak wood tissues during the deciduous stage of the teak host, thereby killing the twigs and eventually the teak tree. Mistletoes are also key players in plant diversity. Therefore, the mistletoe population needs to be regulated not only as a parasite but also as a keystone species affecting biodiversity. Knowledge scarcity on the status of mistletoes includes their genetic variation. Hence, the purpose of this study is to analyze the level of genetic variation of teak mistletoe (Dendrophthoe pentandra) using RAPD markers. At the Padangan teak Clonal Seed Orchard (CSO), leaf samples were randomly collected from three layers of the mistletoe crown (upper, middle, and below) taken from five host teak trees randomly selected from each of the sub-observation measure plots (OMP). Four OMP units inside the observation sample plots (OSP) (n = 3, 50 × 50 m) at different levels of infestation (light, moderate, and heavy) were established. Analysis of genetic variation and genetic distance of mistletoes across different crown layers was conducted using RAPD markers. The leaf samples from crown layers UU (upper crown, subsection upper), UM (upper crown, subsection middle), and UB (upper crown, subsection below), including U (upper crown), had significantly greater genetic variation (He = 0.181–0.255) than those from the M layer (middle crown, He = 0.227) and the B layer (below crown, He = 0.114). Furthermore, the greatest genetic distance occurred between mistletoes in the UB and B crown layers (0.310), whereas the shortest genetic distance occurred between mistletoes of the UU and UM layers in the upper crown (0.038). Practical implications of the low genetic variation include the control of D. pentandra infestation by restricting its population so that the Perhutani State-Owned Forestry Enterprise can maintain damage levels below the economic threshold.
