The presence of soil macrofauna has an important role in maintaining the stability of land ecosystems because they play a role in improving the physical, chemical and biological properties of soil that occur in the immobilization and humification processes. This research aims to analyze the abundance of soil macrofauna and the influence of vegetation types and the environment on the abundance of soil macrofauna in several land covers in Balangan Regency, South Kalimantan. Observations and soil sampling were carried out in a 20 m × 20 m plot using purposive sampling by making 5 subplots measuring 1 m × 1m. This research was carried out on four types of land, namely secondary forests, meranti forests, rubber plantations and empty land. Secondary forest is the only land that has significant differences in the abundance of macro fauna compared to other land uses. Secondary forests have the highest abundance of soil macrofauna, namely 80 individuals/m2, while the lowest is on vacant land at 0 individuals/m2. Secondary forest has the highest diversity, richness and evenness index compared to land cover. The high diversity and abundance of soil macrofauna is influenced by vegetation type, climatic factors (environmental temperature, humidity, light intensity) and edaphic factors (bulk weight, porosity, soil temperature, soil pH, organic C, respiration, litter wet weight, dry weight litter, and water content). Vacant land has the worst soil quality and the lowest abundance of macro fauna, so land reclamation on vacant land needs to be done as soon as possible to avoid soil damage. Key words: secondary forest, soil macro fauna, damaged soil, edaphic, climatic, vegetation

Reklamasi lahan bekas tambang menghadapi tantangan berupa kondisi tanah yang miskin unsur hara dan kurang mendukung pertumbuhan tanaman. Pot organik dan fungi mikoriza arbuskula berpotensi meningkatkan kesuburan media tanam serta mendukung pertumbuhan tanaman. Penelitian ini bertujuan untuk mengevaluasi efektivitas pot organik dan fungi mikoriza arbuskula terhadap pertumbuhan bibit mahoni (Swietenia macrophylla) pada media bekas tambang silika. Penelitian ini menggunakan Rancangan Petak Terbagi/Split plot yaitu dimana petak utama adalah inokulasi mikoriza (M0, M1) dan anak petak adalah komposisi pot organik (Kr1, Kr2, Kr3). Hasil penelitian menunjukkan bahwa komposisi pot organik berpengaruh nyata terhadap Kekakuan lentur (MOE) (kgf/cm2) dan Kekuatan lentur (MOR) (kgf/cm2). Komposisi pot organik dengan pemberian FMA secara bersama-sama memberikan pengaruh nyata terhadap tinggi, biomassa dan kolonisasi. Interaksi antara FMA dan pot organik berpengaruh signifikan terhadap NPA (Nisbah Pucuk Akar). Kombinasi pot organik yaitu F1Kr1 dengan inokulasi mikoriza terbukti paling efektif dalam meningkatkan pertumbuhan bibit mahoni pada media bekas tambang silika.

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.

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.
