Combo nursery technique is a technique where seedlings/cuttings of Shorea leprosula, Gliricidia sepium, and Brachiaria decumbens grass were planted in one polybag to support mining reclamation. To reduce competition effects among the three species, optimum media and size of polybag need to be investigated. The objective of this experiment is to analyse the effect of size of polybag and media composition on the growth of S. leprosula, G. sepium, and B. decumbens grass in the combo nursery technique. The experiment used Randomised Complete Design in Factorial with two factors, i.e. media compositions (soil : compost (2 : 1, v/v), (1 : 1, v/v), (1 : 2, v/v), and soil : compost : rice husk (7:3:1, v/v/v); and size of polybag (15 x 20 cm, 20 x 20 cm, dan 25 x 25 cm). Each treatment had four replications, and each replication consisted of four polybags. The results showed no significant interaction effects between the composition of media and the size of polybag; however, media compositions of soil: compost (1:1) and (1:2), and the sizes of polybag 20 x 20 cm and 25 x 25 cm significantly eliminated competition and significantly increased the growth of S. leprosula and the number of tiller of B. decumbens grass.Keywords: Brachiaria decumbens, Gliricidia sepium, mining reclamation, nursery, Shorea leprosula

Essential oil which is contained on most trees is one of the promising Non-Timber Forest Products (NTFPs) that need to be explored and developed further, for the oil is relatively safe and stores major benefits for local people. There are around 9 -12 types of essential oil that is being developed and one of them is cananga oil, which is available through distillation process of the flowers. The research aims to investigate the ability of cananga to be propagated trough shoot cuttings method, to discover the effects of growing media and plant growth regulators toward the shoot cuttings’ growth and to determine the suitable growth media and plant growth regulators for the cuttings’ development. The collected data were survival rate in percentage, root growth in percentage, height growth, numbers of developed leaf, numbers of developed primary and secondary roots, and also the length of primary roots. The addition of plant growth regulators gave a significant effect toward survival rate (in percentage), height growth and the numbers of developed leaf of the species whereas the addition of growing media and the interaction between the treatments did not give significant effect on the observed traits. All type of media options could be used for cananga shoot cuttings method and the best growth regulator identified in live percentage parameters, high growth and number of leaves on cananga shoot cutting is Rotoone-F. However, in case of rooting, the best growth regulator is found in addition of Rapid root. Keywords: Cuttings, Cananga, Media, Plant Gowth Regulator

The application of silvopasture between the ylang-ylang (Cananga odorata forma enuine) plant and the signal grass (Brachiaria decumbens) has the potential to produce large economic value. The purpose of this study was to determine the response of ylang-ylang seedling growth to competition with grass signals without or with the addition of NPK, and to find out the optimal dose of NPK fertilizer that could help the growth of ylang-ylang seeds planted with grass signals. This study was conducted using a factorial pattern in a complete randomized design with the first factor being planting signal grass and the second factor was adding NPK fertilizer. The results of this study indicate that planting signal grass and adding NPK as much as 0,75 g significantly affected to the growth of ylang-ylang seedlings. The presence of signal grass in the same media showed no inhibition of the growth of ylang-ylang seedlings. The addition of NPK with the dose used did not significantly affect the growth of ylang-ylang seeds. Keywords: Brachiaria decumbens, Cananga odorata, NPK fertilizer dosage, silvopasture

The high economic value of ylang-ylang oil has encouraged some entrepreneurs to develop ylang-ylang plants in Indonesia, especially in terms of increasing productivity. The objectives of this research were to analyze the effect of two types of commercial compost and identify optimal dosage for the growth of ylang-ylang seedlings. The research was carried out through several stages, e.g. the procurement of seeds, weaning, maintenance, collecting and retrieving data, experimental design, hypothesis and data analysis. The research revealed that the use of two types of compost, with four doses used significantly affects the height parameter of the ylang-ylang seedlings. The use of doses of 25 g was able to increase the growth of ylang-ylang seeds better than other doses. Keywords: commercial, compost, ylang-ylang

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.

Cajeput (Melaleuca cajuputi) is widely used as a post-mining revegetation plant. The addition of organic matter to post-mining land can improve the physical, chemical, and biological conditions of the soil that lead on to increasing growth and endurance of cajeput in polluted land by acid mine drainage. This study aims to analyze the effect of compost mixture media and roasted husk mixture media to endurance and growth of cajeput seedling and also to analyze the effect of acid mine drainage concentration on the endurances of cajeput seedling on various media. This study used a completely randomized design with two factors consisting of acid mine drainage concentration and type of media. The results of this study indicate that the concentration of acid mine drainage has no significant effect on the growth of height, diameter, and number of leaves, also on total wet weight, total dry weight, moisture content, and root length while the type of media used has a significant effect on growth in height, diameter, and the number of leaves. Keywords: acid mine drainage, compost, Melaleuca cajuputi, roasted husk

Drought and water logging stress are the most critical environmental factors that affect tree seedling survival and growth in the field. In this study, 12 populations of white jabon (Neolamarckia cadamba (Roxb.) Bosser) were evaluated to determine the genetic variability among populations and correlation among morphophysiological seedling characters under drought and water logging stresses. Two research units were carried out by the randomized complete design with 2 x 12 factorial arrangements, i.e. (1) drought stress (2 treatments) and population (12 populations), and (2) water logging stress (2 treatments) and population (12 populations). Results showed that the responses of seedling traits were varied among populations under drought and waterlogging stresses. White Jabon seedling has higher adaptation to water logging stress than to drought stress. Kampar and Gowa populations have better adaptation to water logging stress. In drought stress, Gowa population had better adaptation followed by Nusa Kambangan population. Seedling height, total biomass and proline content characters based on value of broad sense heritability and correlation among characters, could be considered as important indicators for improvement programs for drought tolerance, while in the water logging stress, height, total biomass, root length and leaf area could be considered as important indicators for improvement program of white Jabon for tolerance on waterlogged sites.
