Acid mine drainage (AMD) is one of the most serious environmental impacts of mining, characterized by low pH and high metal content. This study aimed to evaluate the neutralization efficiency of waste-based granules made from fly ash, bottom ash (FABA), and goat manure for AMD treatment under laboratory conditions. Two types of granules were produced: (i) 45% fly ash, 45% bottom ash, and 10% cement; and (ii) 45% fly ash, 30% bottom ash, 15% goat manure, and 10% cement. Each type was applied at different volumes (10%, 30%, and 50%) and positions (bottom and suspended) for 48 hours. Results showed that granule type, volume, and placement significantly influenced pH neutralization and metal removal. The best performance was achieved by the suspended granule without manure at 50%, raising AMD pH from 2.45 to 9.17 within 3 hours, with 88.7% Fe and 66.5% Mn removal. XRD and Micro-XRF analyses confirmed that neutralization occurred through dissolution of Ca-based minerals and formation of calcite and gypsum. The study demonstrates that FABA granules offer a low-cost, sustainable option for AMD treatment and can serve as a contextual learning model in environmental and chemistry education, linking waste utilization with real-world applications of acid-base reactions and environmental sustainability.

The essential oil industry produces large amounts of underutilized solid waste containing lignocellulosic compounds that can potentially support the growth of edible mushrooms. This research was conducted to evaluate the potential utilization of solid waste from citronella (Cymbopogon nardus (L.) Rendle) and patchouli (Pogostemon cablin (Blanco) Benth.) as alternative substrates for oyster mushroom (Pleurotus spp.) cultivation. The experimental design employed a completely randomized factorial design incorporating two treatment factors: oyster mushroom varieties (white and brown strains) and eight substrate composition variations, with one control treatment serving as a baseline comparison. Substrate formulations were developed using various combinations of citronella and patchouli waste mixed with conventional materials. The results demonstrated that aromatic waste-based substrates with balanced formulations, specifically M1, M2, and M5, produced significantly higher fresh weights and fruiting body counts, closely approaching the performance of the control treatment (M0B1), which recorded the highest biological efficiency of 42.37% within a cultivation period of approximately 56 days. Conversely, single dominant waste substrates, such as M3 and M6, yielded smaller fruiting bodies and lower total biomass production. Statistical analysis revealed a positive correlation between fruiting body quantity and fresh weight, supporting the use of morphological traits as reliable indicators of cultivation productivity. These findings highlight the significant potential of essential oil industry waste as a sustainable and economically viable alternative cultivation medium for oyster mushroom production, provided that substrates are formulated with appropriate proportional compositions and are properly adapted to their specific chemical characteristics and nutritional properties. Keywords: biological efficiency, citronella, growth media, patchouli, Pleurotus spp.

Introduction turfgrass varieties require fertilization with high dosage, but it can contaminate environment. The increasing efficiency of fertilizer absorbtion was expected to reduce fertilizer requirement. The experiment was conducted to study the effect of arbuscular mycorrhizae and Azospirillum sp. on nutrient uptake, fertilization efficiency, growth and visual quality of turfgrass. The experiment consisted of two factors, i.e. the dosages of fertilizer and inoculant types. The dosages of fertilizer were the relatif dosage from recommended dosage (RD) i.e 100%RD, 75%RD, 50%RD, and 25%RD. The recommended dosage was 0.5 kg N + 1.5 kg P2O5 + 0.5 kg K2O per 100 m2/month by compound fertilizer (15-15-15). The treatment of 100%RD without inoculant was used as control. The inoculant types were no inoculant, arbuscular mycorrhizal fungi (AMF), Azospirillum sp., and AMF+Azospirillum sp. Factorial experiment was arranged in Randomized Block Design with three replications. The results showed that interaction between inoculant type and dosage of fertilizer affected nutrient uptake, fertilizer efficiency, growth, and visual quality. AMF inoculation and 25%RD increased shoot N uptake and N fertilizer efficiency, compared with control. Azospirillum sp. inoculation at 75% RD increased shoot N concentration, but did not affect on shoot N uptake and N fertilizer efficiency compared with control. Inoculant did not affect shoot P concentration, shoot P uptake, and P fertilizer efficiency. Azospirillum and AMF+Azospirillum inoculation increased shoot K concentration. AMF+Azospirillum inoculation and 100%RD increased shoot N concentration and shoot N uptake, compared with control. Key words : Arbuscular mycorrhizal fungi, Azospirillum, fertilizer efficiency, nutrient uptake, turfgrass.

The aim of this research was to evaluate growth and yield in response to aluminum (Al) stress in several genotypes of chilli (Capsicum annuum L.). The research was conducted in University Farm of IPB, Cikabayan, Bogor from February to August 2006. Ultisol soils from Gajrug (Lebak, Banten) in polybag with pH 4.2, Al-dd 30.08 me/ 100 g and Al-saturated 83.81% was used in this experiment. Eight genotypes of chilli (4 tolerant and 4sensitive) were tested on two different conditions, in media without Al-stress condition (Al-saturated 0.77%) and wich Al-stress (Al-saturated 60.85%). Characters observed were plant height, shoot dry-weight, total number of fruits per plant, number of fruit harvested per plant, fruit dimension (length and diameter), fruit weight harvested per plant, and weight of each fruit. The results showed that there were differences of response to Al-stress among genotypes on the study. PBC 619 and Jatilaba were selected as tolerant genotypes, while Cilibangi 3 and Helm were sensitive. This evaluation of agronomic characters for tolerant and sensitive to Al-stress appeared very consistent with root bioassay results. Based on this result, the root bioassay method can be used to select chili genotypes for Al-stress tolerance. Key words: Growth and yield evaluation, aluminum stress, Capsicum annuum, ultisol soil.

The aim of this research was to test the utilization of arbuscular mycorrhizal fungus (AMF) to improve adaptation ability of chili to aluminum (Al) stress based on growth and yield response in four genotypes of chili (Capsicum annuum L.). The research was carried out at University Farm of IPB in Cikabayan from September 2006 to Maret 2007. The media was Ultisol from Gajrug (Lebak, Banten) in polybag. Four genotypes of chili, PBC 619 and Jatilaba (Al tolerant genotypes), and Cilibangi 3 and Helm (Al sensitive genotypes) were treated with and without inoculation of Gigaspora margarita, and planted further in media without Al stress (Al saturation 0.77%) and Al stress (Al saturation 60.85%). Variables observed were degree of AMF infection, root length, plant height, shoot dry weight, number of harvested fruits, fruit length, fruit weight and weight of harvested fruits. The results showed that inoculation of G. margarita effectively decreased negative influence of Al stress by increasing plant height, shoot dry weight, number of harvested fruit, fruit length, weight per fruit and weight of harvested fruits. Inoculation of G. margarita to Al sensitive genotypes was more advantageous than to tolerant genotypes. The Al sensitive genotypes were adapted to Al stress if they were inoculated with G. margarita. In Al stress condition, inoculation of G. margarita to Al sensitive genotypes increased weight of harvested fruits up to 94.49% in Cilibangi 3 and 80.37% in Helm. Key words: Adaptation, aluminum stress, arbuscular mycorrhizal fungus, Capsicum annuum L., Ultisol

Waterlogged condition is one of the environmental stresses unfavorable for plants and mycorrhizal fungi. Arbuscular Mycorrhizal (AM) species that are tolerant tend to be more adaptive to waterlogged conditions. Besides increasing plant tolerance, the documented effects of AM fungi (AMF) inoculation on wetland plant performance remain inconsistent, and AMF application may also cause plant growth depression under waterlogging. This study aimed to examine the morpho-anatomical adaptation, survival, growth, biomass, and nutrient uptake of Nauclea orientalis (L.) seedlings from different habitats inoculated with Arbuscular Mycorrhizal Fungi under waterlogged conditions for 90 days. Experimental procedures included seed germination, preparation of AMF inoculum, inoculation, and waterlogging treatment. The results showed that N. orientalis seedlings formed lenticels (100%), adventitious roots (41%), and aerenchyma under waterlogged conditions. Seedlings originating from dryland habitats, both mycorrhizal and non-mycorrhizal, had lower height growth rate compared to those from other habitat types. Similar patterns were observed in relative growth rate for shoot (RGRs), root (RGRr), total (RGRt), and root-to-shoot ratio. Treatments of swamp habitat seedlings without waterlogging and with waterlogging, as well as savannah seedlings under waterlogged conditions, showed higher total plant dry weight and RGRt than other treatments. In general, total nitrogen concentration in roots and shoots was highest in the interaction between swamp habitat seedlings and non-mycorrhizal treatment under waterlogging. However, seedlings from dryland habitats required AMF under waterlogging to improve biomass and nitrogen accumulation in roots. Independently, waterlogging increased average height gain (18%), stem diameter (46%), leaf area (40%), leaf length (17%), and leaf width (21%). Nonetheless, waterlogged treatment decreased the number of leaves (9%) and AMF colonization (71%). The results indicate that seedlings from temporary swamp habitats demonstrated better growth performance and higher biomass under waterlogged conditions, regardless of AMF inoculation.

Genetic parameters for early growth of Neolamarckia cadamba, an indigenous species with potential as a source of timber wood, were estimated in open-pollinated provenance–progeny tests conducted at two sites in West Java Province, Indonesia. The experiment was arranged in a randomized complete block design with 12 provenances, 105 families, and five replications in four-tree row plots. Total height and root collar diameter were measured at 18 months of age. Significant differences among provenances and among families within provenances were observed for height and collar diameter at all sites, except for collar diameter among provenances at the Parungpanjang site. In general, the Garut (GSJ) provenance performed better than the Kualakencana (KKP) and Nusa Kambangan (NKJ) provenances at both sites. Evaluation of variance components at the two sites showed that the provenance effects (ranging from 0.5 to 1.7%) contributed more to the total variance than family-within-provenance effects (ranging from 0.4 to 0.6%). Genetic correlations between height and collar diameter were weak to moderate. Heritability estimates were low for all traits at Limbangan, whereas they were moderate at Parungpanjang. Estimated genetic gain for height and diameter based on proportional family selection of 0.30 was 0.13 and 0.18 at Limbangan, and 0.31 and 0.16 at Parungpanjang, respectively. Continued heritability measurement is required to obtain stable values. Stable heritability combined with family selection and within-family selection will improve genetic gain.

EVALUATION OF REVEGETATION PRACTICES IN POST-MINED AREAS OF INDONESIA Meilina Wijayanti; Gerald Kapp; Irdika Mansur

In compliance with government regulations, mining companies in Indonesia are obliged to reclaim and return post-mined areas to their pre-mining condition. Revegetation, as part of reclamation activities, plays a significant role in the rehabilitation of degraded post-mined areas to restore their productive land uses. Hence, this study aimed to assess tree growth on reclamation sites across four mining companies in East Kalimantan, South Sulawesi, South Sumatra, and West Java in Indonesia, and to evaluate whether the companies have met the legal requirements set for site revegetation. The success parameters were based on the applicable regulations of the Ministry of Environment and Forestry (MOEF) P.60/Menhut-II/2009 and tree growth parameters (stem diameter, total height, and basal area). The parameters set by MOEF included revegetation realization, survival rate, tree density, tree health, species composition, and rotation length. The four mining companies applied the two-phase planting method that included the planting of Enterolobium cyclocarpum for the first phase; and in the second phase, the slow-growing native species such as Intsia palembanica, Syzygium polyanthum, Shorea spp., and Elmerillia tsiampaca. The tree growth parameters showed different performances across species and reclaimed sites. An extremely high growth of stem basal area—57.6 m²/ha in 11 years—was recorded in the E. cyclocarpum stand of the mining company in South Sulawesi. All four mining companies strived to comply with the regulation, with scores of revegetation success ranging from 15 to 25 out of 25 possible points. However, these favorable results may not be representative of all mining companies, as those assessed were only companies voluntarily supporting this research. Moreover, each of the four companies made distinct efforts in implementing post-mining revegetation, such as establishing plots of Melaleuca cajuputi producing cajuput oil and polycultures of native species.
