Ebony (Diospyros celebica Bakh.) is a slow-growing species that is an impacting factor in the extinction of this species. Efforts to reduce the ebony population can be performed by employing microbes to stimulate ebony growth. This study aimed to obtain bacterial isolates with the potential of producing IAA and GA3 that can be further utilized as biofertilizer agents. Research stages encompassed soil sample isolation, isolation of bacteria, and analysis of IAA and GA3. The research was in complete randomized design (CRD). Thirteen isolates were successfully purified and analyzed with their IAA and GA3 hormones. The highest IAA concentrations were observed in EP1b at 48 incubation hours (44.39 ppm), EP3d at 72 incubation hours (34.93 ppm), and EP3c at 72 incubation hours (34.48 ppm). EP2c, EP2e, and EP2a produced the highest GA3 concentration at 24 incubation hours which were 3.88 ppm, 3.88 ppm, and 3.81 ppm, respectively.

We have focused our research on determining whether the timbers used as a building material by the population today are resistant or nonresistant to termite damage. The main purpose of this was to learn which types of trees cannot be used as building materials for houses or other structures. In this, we used Salix, Populus, Aleagnus, Ulmus, Pinus, and Betula wood species. We carried out research both in the laboratory and in the field (termite nests and residential buildings). In this case, damage by termites of these pieces of wood placed around termite nests accounts for one year. Salix and Populus wood materials were 86.6±6/50.0±4 percent in laboratory conditions, 93.3±5/90±5 in home, and Pinus and Betula wood materials were 6.6±0.7/0 in laboratory conditions and 13, 3±2/3.3±0.8 percent in home were damage noted. The causes of serious damage to wooden materials by termites are mainly due to the increase of humidity and the growth of fungi. When fungal cultures were isolated from damaged wood and their morphological characteristics were studied, it was found that wood decay fungi belonging to the genera Alternaria and Cladosporium were present. When studying the content of substances difficult to decompose by enzymes and microorganisms in the wood materials, it was found lignin that 20.1±0.3% was present in Salix and 41.2±0.3% in Betula wood. It has been found that in areas with high humidity, wood materials are decomposed by fungi and other microorganisms and the microorganisms multiply faster, As a result, wood more damage by termites. Lignin and some of its compounds prevent the growth of microorganisms. Wood materials made from trees belonging to the genera Pinus and Betula are resistant to termite damage due to their high lignin content.
