Drought is one of the environmental factors that can inhibit plant growth and production. Arbuscular mycorrhizal fungi (AMF) were reported to increase plant growth and tolerance to drought stress. Pterocarpus indicus seedlings were inoculated with three AMF treatments (control, Clarodeoglomus. etunicatum, and Septoglomus constrictum) at three watering intervals (watering every day, every two days, and three days) on a greenhouse scale. The results showed that the interaction of C. etunicatum and S. constrictum at various watering intervals effectively increased the height growth of Angsana seedlings. C. etunicatum and S. constrictum and daily watering each increased the diameter of the seedlings. The dry weight of seedlings and the number of root nodules of Angsana seedlings increased in various AMF treatments under daily watering conditions and tended to decrease with watering intervals. Local AMF has the potential to be developed to support the reforestation and conservation of the Angsana species in various land conditions, especially dry land

This study aims to determine the levels and nutrient uptake of kayu kuku (Pericopsis mooniana Thwaites) mycorrhizal plants aged four months in post-gold mining field scale. Sampling was carried out in the post-Bombana gold mining area. Leaf drying and weighing wass carried out at the Laboratory of the Faculty of Forestry and Environmental Sciences, Halu Oleo University and measurement of nutrient content and uptake at the SEAMEO BIOTROP Soil and Plants Laboratory Bogor, this study started from May to Jully 2021. This research method used a Randomized Block Design (RBD) with 4 treatments, namely control (A), G. coronatum (B), G. claroideum (C) and mixed AMF (B+C). This study was divided into 3 groups where each group contained 1 plant so that the total plants used are 12 kayu kuku plants. The results showed that AMF G. coronatum significantly increased N, P and Mn nutrient levels. Mixed AMF (G. coronatum + G. claroideum) was effective in increasing nutrient uptake of N, P, Mn and Fe. AMF was effective in increasing the levels and nutrient uptake of the four month old P. mooniana on post-Gold Mining

The purpose of this study was to determine the effectiveness of AMF types on the increasing growth of Lonkida (Nauclea orientalis L.) plants under salinity stress conditions. This study was carried out in the plastic home of the Indonesian Mycorrhizal Association Southeast Sulawesi branch, Kendari City and Forestry Laboratory, for five months, march - July 2019. This study used a Factorial Completely Randomized Design consisting of 3 replications and three plant units. The first factor included treatment without AMF, Acaulospora sp1. and Clorideglomus etunicatum. The second factor includes Salinity 0 mM, 50 mM, 100 mM, 150 mM and 200 mM. The results showed that the interaction of AMF and salinity was not effective in increasing plant growth. Inoculation of AMF type C. etunicatum can increase height, plant dry weight, root shoot ratio, seed quality index, and root colonization. N. orientalis has a high dependence on arbuscular mycorrhizal fungi. Giving 0 mM salinity increases height, diameter, number of leaves, plant dry weight, and seed quality index

The aim of this research is to find out the potential of tree stands in the private forest of Latoma Village. Research using quantitative, descriptive methods in this study is intended to obtain an overview and information regarding data on the potential of tree stands in private forest areas. From the results of data collection, it was found that the number of trees successfully recorded was a total of 25 tree species, all of which were woody plants in the form of trees (trees) with a diameter class of 20-60 cm. There are 3 types of trees in the private forest, so the dominant trees are in the mixed-species class, Commercial class two, with a percentage of 79%, Meranti wood species class, commercial one class, 18%, and beautiful class two, 3%. It can be seen that the distribution of diameter classes for all species groups is fairly even. with a total volume per plot of 90.35 m^3/Ha, and the total number of trees found was 135 trees. Based on these results, if converted to the total area of Private Forest, the total volume is 10,039.32 m^3/Ha and the total number of trees is 15,000 trees.

This study aims to determine the viability of Kayu Kuku seeds which are influenced by the treatment of seed storage age and gibberellin hormone. This research was conducted at the Plastic House of the Arbuscular Mycorrhizal Association, Southeast Sulawesi Branch. Using the Completely Randomized Design (CRD) factorial method and repeated 3 times so that it requires 900 seeds in amount. The results showed that the interaction of treatment with storage age 0 years and without gibberellins had the highest average value on the variable percentage of germination (96%), germination (93%), the average seed germination per day (MDG) (3,20), and the interaction of 1 year seed storage age and 150 ppm gibberellin concentration gave the highest value to the variable time to germination (MGT) of 6.60. Therefore, nail wood seeds need to be germinated directly without going through annual storage and without giving gibberellins concentration.

Hutan mangrove merupakan hutan yang tumbuh di sepanjang pantai, di daerah pasang surut, atau di muara sungai. Struktur vegetasi mangrove memegang peranan penting bagi kehidupan baik secara fisik, ekologi dan ekonomi. Penelitian ini bertujuan untuk : (1) mengetahui jenis mangrove, (2) mengetahui Indeks Nilai Penting (INP) struktur vegetasi mangrove, (3) mebgetahui data parameter lingkungan masing-masing stasiun yang ada di Pesisir Tabongo Kecamatan Dulupi Kabupaten Boalemo. Penelitian ini dilaksanakan selama 7 bulan muli dari bulan Februari-Agustus 2023. Metode yang digunakan dalam penelitian ini adalah metode survei dengan pendekatan deskriptif kuantitatif, pengambilan data dilakukan dengan menggunakan metode plot berpetak, ukuran plot 20x20 m untuk tingkat pohon, 10x10 m tingkat pancang, dan 5x5 m tingkat semai. Dari hasil penelitian di Pesisir Tabongo ditemukan ada 6 spesies yaitu spesies Sonneratia alba, Rhizophora apiculata, Rhizophora mucronata, Ceriops tagal, Bruguiera gymnorrhiza, dan Avicennia alba. Hasil perhitungan INP struktur vegetasi pada stasiun I di dominasi oleh spesies C. tagal dengan nilai INP 73,02%. Pada stasiun II di dominasi oleh spesies S. alba dengan nilai INP 98,72%. Terdapat perbedaan nilai parameter lingkungan di masing-masing stasiun. Stasiun I kelembaban berada pada nilai 68%, suhu udara 32°C, pH tanah 7 dan pH air 6,92. Stasiun II kelembaban berada pada nilai 60, suhu udara 35°C, pH tanah 7 dan pH air 7,39. Mangrove forests area forests that grow along the coast, in tidal areas, or at river mouth. The vegetation structure of mangroves plays a crucial role in physical, ecological, and economic aspects of life. This research aimed to: (1) identify mangrove species, (2) determine the Importance Value Indeks (INP) of mangrove vegetation structure, (3) collect environmental parameter data for each station along the Tabongo Coast in Dulupi Subdistrict, Boalemo Regency. This study was conductedover 7 month, from February to August 2023. The research method employed in this study was a survey method with a quantitative descriptive approach, data collection was done using quadrat plot method, with plot size of 20x20m for tree level, 10x10 m for sapling level, and 5x5 m seedling level. From the results on the Tabongo Coast, 6 species were found:Sonneratia alba, Rhizophora apiculata, Rhizophora mucronata, Ceriops tagal, Bruguiera gymnorrhiza, and Avicennia alba. The calculation of INP for vegetation structure at station I was dominatedby C. tagal with an INP value of 73.02%. At station II, it was dominated by S. alba with an INP value 98.72%. There were differences in environmental parameter values at each station. Station I had a humidity value of 68%, air temperature of 32°C, soil pH of 7 and water pH of 6.92. Station II had a humidity valueof 60%, air temperature of 35°C, soil pH of 7 and water pH of 7,39.
