The study was carried out for investigation of the adaptability of white jabon seedlings from 12 populations to drought and water logging stresses in a controlled green house. The results showed that the adaptive responses of white jabon seedling to drought and waterlogging stresses were affected by genotype (population). The drought and waterlogging stresses significantly inhibited plant growth, biomass accumulation and allocation, leaf area, also decreased chlorophyll content, increased carotenoids contents, and accumulated free proline. Relative water content and specific leaf area tended to be higher in waterlogging and declined in drought stresses. The result clearly indicated that white jabon seedlings were more adaptive to waterlogging than to drought stresses. Moreover, there were different responses to drought and waterlogging stresses between the twelve populations. Kampar, Gowa, Kuala Kencana and OKI populations exhibited higher growth performance and stress tolerance index to be adapted to waterlogging stress, while Gowa, Pomalaa and Kampar populations had relatively better growth performance in the drought stress.

The application of remote sensing using Unmanned Aerial Vehicle (UAV) technology to identify distribution of Acid Mine Drainage (AMD) as part of mitigation process has been done in PT. Jorong Barutama Greston. UAV imagery was interpreted visually to produce land cover map. Bare land area from land cover map is used as the boundary of the analysis area for the mitigation of AMD source. Color of soil in UAV images is used as training area for supervised classification to differentiate different pH. The result shows distribution of soil with pH between 2-3 is 1.2 ha, pH 3-4 is 4.5 ha, and pH 4-5 is 9 ha. This analysis can show that mapping results using aerial photo is effective to identify pH of soil in bare land as a source of acid to water in void and it used as input for revegetation and swamp forest planning as bio-phytoremediation efforts. Swamp forest as a wetland is one recomendation for sustainable water management on mine to increase pH and reduce heavy metal content. The success of constructed swamp forest as passive treatment for bio-phytoremediation is determined by the selection of plant species, site location, design and construction of swamp forest and maintenance. Typha latifolia, Salvinia sp., Fimbristylis globulosa, Chrysopogon zizanioides, Melaleuca leucadendra, Melaleuca cajuputi, Nauclea subdita and Nauclea orientalis L. are recom-mended as local selected plants for phytoremediation. Obtained six variables that significantly affected to determination of site location for constructed swamp forest are elevation (T), slope (S), land cover (L), cathment area (C), distance from channel (K) and distance from the monitoring pool (P). The model X = 0.2T + 0.2S + 0.1L + 0.15C + 0.3K + 0.05P applied to find very suit-able area with α = 0.05 and the R-square (R2) value 93.4%.

Arbuscular mycorrhizal fungi is a phylum of Glomeromycota. Arbuscular mycorrhizal fungi (AMF) propagule are spores, mycor-rhizal fungal hyphae and infected root fragments. The aims of this research were to analyze the effectivity of root inoculum of AMF to enhance teak (Tectona grandis Linn F.) seedling growth. The research was used complete randomized design (CRD)-split plot design. The main plot was root inoculum of AMF, sub plot is a media sterilization and media is not sterilized. The results showed that root inoculum of AMF and media effectively improved teak growth, especially in height, diameter, and shoot dry weight. Root inoculum of AMF is able to be used as the source of inoculum for the growth teak seedling. Fresh inoculum was found to be better than root inoculum stored at room temperature and root inoculum stored at refrigerator temperature (5°C). Storage of root inocu-lum at room temperature and refrigerator temperature (5°C) for two weeks decreased the effectiveness of inoculum. Type of mixed inoculum and inoculum of Acaulospora sp. root resulted in better growth compared with G. clarum root inoculum.

Abu terbang digunakan sebagai bahan campuran alternatif dalam pengomposan ampas daun sereh wangi sebagai pengganti dolomit. Campuran ampas daun sereh wangi dengan 2%, 5%, 10%, dan 15% abu terbang, ditambah 2% dolomit maupun tanpa penambahan bahan alkali dikomposkan terlebih dahulu. Kompos ditambahkan ke dalam tanah dengan perbandingan 1:1 b/b untuk mengetahui pengaruhnya terhadap pertumbuhan Cananga odorata. Parameter pertumbuhan yang diamati yaitu pertambahan tinggi dan diameter tanaman, jumlah akar sekunder, panjang akar, berat kering pucuk dan akar, biomassa total, serapan hara, serta nisbah pucuk akar yang dianalisis 6 minggu setelah tanam. Analisis kandungan C-organik, N, P, K, Cu, Mn, Cd, Pb, dan As dilakukan pada media dan jaringan tanaman yang mendapat perlakuan tanah dengan penambahan kompos dari campuran ampas daun sereh wangi dengan 15% abu terbang (P6) dan dibandingkan dengan kandungan nutrisi yang sama pada media tanah tanpa kompos (K) maupun media dengan kompos dari campuran ampas daun sereh wangi dengan 2% dolomit (P2). Perlakuan P6 menghasilkan N, P dan K total yang cenderung tinggi, meningkatkan akumulasi dan serapan N hingga 20%, serta pH media tanam yang stabil pada kondisi netral. Perlakuan P6 juga menghasilkan konsentrasi Pb, Mn, Cu, As dan Cd dalam media tanam, serta akumulasinya dalam jaringan C. odorata yang rendah. Perlakuan P6 ke dalam tanah dapat menurunkan akumulasi Mn dan Cu dalam jaringan C. odorata. Berdasarkan hasil tersebut, kompos dengan campuran abu terbang dapat dimanfaatkan sebagai bahan alternatif pengganti kompos dengan campuran dolomit.

Soil fertility in land after nickel mining has a change in soil texture that changes both the profile color and the soil irregularity. Damage to the physical properties of the soil affects the soil nutrients needed by plants. Several physical and chemical properties of soil are influenced by texture including soil plasticity, soil permeability, ease of cultivation, lack of soil fertility and productivity. Stable soil fertility can support plant growth. Damage to the physical properties of the soil due to the loss of the soil interest (solum) by the ongoing washing of the soil. This results in the loss of some cations in soil colloids, resulting in low acidity (pH) of the soil becoming acidic. Cation Exchange Capacity (CEC) as the amount of charge of cations absorbed by soil colloids at a certain pH. Another factor in the decline in CEC is the decreasing number of cation nutrients that can be exchanged. The relationship with reclaimed and revegetated land is influenced by climatic factors with rainfall intensity. Soil fertility on revegetated land with CEC value and C-organic content was very low. Such soil fertility conditions are found in the revegetated zone with large leaf acacia (A. mangium) vegetation; sengon (P. falcataria); ketapang (T. catappa) and waru (H. tiliaceus). Soils that have low soil nutrient content are characterized by low organic matter content, very low available P content, and low cation exchange capacity.

Silvopasture system improvement in managing post-mining land resources has been done by searching for a quality grass. One of the selected grass species is signal grass (Brachiaria decumbens Stapf.). This research aimed to prepare signal grass through the inoculation of AMF Claroideoglomus etunicatum, as an effort to enrich its growth before being applied to post-mining soil. Research stages included the AMF inoculation on signal grass through spore culture and then transferred the colonized grass to the pot using sterile zeolite as a growth medium. The treatment on the first stage was without and with AMF inoculation (dose of 20 spores) on signal grass which was repeated for 12 times. Incubation in a spore culture was 4 weeks while incubation in a pot containing sterile zeolite medium was 8 weeks. Research data were analyzed using the Shapiro-Wilk’s normality test, Independent Sample T-test, and Pearson’s correlation test. Observation results showed that the inoculation of C. etunicatum on signal grass was significantly impact on the increase of plant height, stem diameter, number of leaves, number of tillers, shoot and root fresh weight, and shoot dry weight (p <0.05). Microscopic observation showed that there was AMF colonization on treated signal grass roots in the amount of 55 ± 0.06 % with number of spores was 252 ± 9.82 per 10 g zeolites, while AMF infection was not found in uninoculated signal grass. It is expected that by providing signal grass inoculated with AMF C. etunicatum would support its growth in post-mining land for Silvopasture system.

Fungi mikoriza arbuskula (FMA) sebagai agensia hayati pada beberapa jenis tanaman saat ini mulai banyak mendapat perhatian, karena kemampuannya dalam bersimbiosis dengan berbagai jenis tanaman, dan membantu tanaman dalam meningkatkan penyerapan unsur hara, serta memperbaiki kualitas hasil. Dewasa ini, penting artinya mendapatkan bahan alternatif yang dapat digunakan sebagai sumber fosfor (P) yang harganya murah, aman bagi lingkungan, dan mudah tersedia. Batuan fosfat dan tepung tulang sapi merupakan jenis bahan alami yang dapat digunakan sebagai sumber P alternatif yang diharapkan dapat meningkatkan pertumbuhan dan biomassa tanaman pegagan. Percobaan rumah kaca dilaksanakan dengan tujuan menguji efektivitas FMA pada jenis dan dosis pupuk P alami terhadap pertumbuhan dan biomassa tanaman pegagan (Centella asiatica (L.) Urban). Percobaan menggunakan rancangan acak lengkap yang disusun secara faktorial. Faktor pertama ialah perlakuan FMA (inokulasi FMA dan tanpa FMA). Faktor kedua ialah dosis pupuk P alami (4 taraf dosis batuan fosfat 150, 300, 450, 600 kg ha-1 dan 4 taraf dosis tepung tulang sapi 125, 250, 375, 500 kg ha-1 serta perlakuan kontrol/tanpa pemupukan), yang diulang tiga kali. Hasil penelitian menunjukkan inokulasi FMA nyata meningkatkan jumlah daun, jumlah stolon, luas daun, bobot segar dan bobot kering biomassa tanaman pegagan. Demikian pula Pupuk P alami nyata meningkatkan jumlah daun, luas daun, bobot segar dan bobot kering biomassa tanaman pegagan. Perlakuan FMA dan pupuk P alami tidak saling berinteraksi terhadap peubah pertumbuhan dan biomassa tanaman pegagan.
