Abstract

 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. Keywords: Anthocephalus cadamba, genotype, growth, population, stress tolerance index

Abstract

The main problem encountered by soybean crop in acid sulfate tidal lands is less availability of P, because of its chemical bond with Fe. Heavy dose of  fertilization often lead to high fertilizer residue, wich could be used for crops farming using AMF. Research was conducted to study the effect of soybean culturing technique and AMF inoculants source on growth of  soybean. The treatments consisted two factors, arranged in a randomized block design with three replications. The first factor was four inoculants sources of AMF, namely AMF and without inoculation AMF, inoculants from rhizospheres of kudzu (Pueraria javanica), sorghum (Sorghum bicolor), corn (Zea mays) and soybean (Glycine max). The second factor was culturing tehnique, namely water saturated and dry soil culture. Soybeans were grown in pots containing 5 kg soil derived from tidal land,  Simpang Village, District of Berbak, East Tanjung Jabung Regency,  Jambi Province. Results showed that the interaction saturated soil culture with inoculants from corn’s rhizosphere had positive effect on the variability of N, P and K uptake, N and P content in the plant, relative efficiency of inoculants and relative efficiency of P uptake, stem diameter, biomass dry weight, the number of filled pods and seed dry weight of soybeans. Dry soil culture with inoculants of corn’s rhizosphere had greater root colonization, but overall for the growth and grain yield of soybean, saturated soil culture with inoculants from corn rhizosphere has better effect on other growth variables.

Abstract

Merbau [Intsia bijuga (Colebr.) O. Kuntze] is one of valuable timber tree in south-east Asia which has been known having ectomycorrhizae (EcM) though being ignored. Identification of the ectomycorrizae is prime important for being basis of further studies. This study investigated the EcM fungi associated with Merbau by using both sporocarp morphology and EcM morphotypes. Morphological characters of sporocarps and basidiocarps of the fungi and EcM morphotypes obtained from seedlings and trees from natural and plantation stands of merbau, as well as from nurseries were compared to the description of those resulted from baiting method. Only one species of ectomycorrhizal fungus was found associated with merbau [Intsia bijuga (Colebr.) Kuntze] which has not been described yet. The fungus formed mycorrhizae with monopodial pinnate branching. The fungus was identified belonging to the genus of Scleroderma. The fungus was more common to occur beneath merbau seedlings than trees. The sporocarps may be yielded under greenhouse condition and could be cultured in MMN agar media, thus it facilitates to the production of inoculums used for further studies.

Abstract

The Indonesian Government accommodates the development of mining sector conducted in forest area based on Forestry Law Number 41/1999 by the scheme of Forest Leasehold License. Reclamation is required to remediate the degraded land caused by mining activity to restore forest structure and function. This study aimed to analyze the implementation of mining reclamation in East Kalimantan forest areas based on its institutional performance. This study is a descriptive qualitative study that implemented the institutional framework of Situation-Structure-Behavior-Performance. From the study, we found that there are 143,804.89 ha of forest area borrowed by 90 units of Forest Leasehold License for coal and mineral mining in East Kalimantan with reclamation progress reached 41.35% over the disturbed areas. Based on institutional performance analysis, it is identified that the challenges in mining reclamation in East Kalimantan forest areas related to regulation, low sanction enforcement, lack of budget, human resource and economic incentives, and the absence of low-cost technology for mining reclamation monitoring and evaluation. Therefore, development of proper regulations is urgently required to improve stakeholder behavior while enhancement of human resource, technology, and law enforcement are also urgent to improve institutional performance of mining reclamation.Keywords:

Abstract

Mining is still considered to be an essential sector to gain national income and to provide energy supply. Forest Leasehold License (FLL) is a mechanism to accommodate the non-forestry sector, including mining development in the forest area. This license is a form of transfer of right given from Minister of Environment and Forestry to a mining license holder. Transfer of right by FLL contractual shaped jurisdictional boundary that is one of the obligations that has to be complied by FLL holder is to conduct mining reclamation. This study aimed to analyze the effects of FLL and its jurisdictional boundary on mining reclamation performance in East Kalimantan forest areas. It is a descriptive qualitative study based implemented the agency theory with the institutional approach. The study found that mining permit and FLL is a temporary transfer of right. The emerging problem in the FLL and its jurisdictional boundary related to asymmetric information and transaction cost caused moral hazards such as adverse risk selection of FLL holders by the principal, reclamation ignorance by the agent, and opportunism both from principal and agent. These agency problems affect FLL reclamation performance that just reached 41.35% over disturbed areas. Institutional challenges are due to the regulation gap creating a conflict of interest, budget and human resource constrain, cost center activity, and lack of economic incentive as well as lack of coordination among the government institutions. The research findings suggested inputs for institutional arrangement in terms of transfer of the right, including FLL reclamation process business, to improve its performance in the East Kalimantan forest area.

Abstract

This paper examines the identification of key indicators that could be used to measure the success of reclamation plants in post-exploration oil and gas mining areas. The main objective of this research was to find key indicators or variables for evaluating the level success of reclamation results in the post-mining of oil and gas area. In this study, 44 environmental variables of the physical, biological, soil, water and air indicators were analyzed from 70 field plots of 6 reclamation and 2 natural forest sites. The analysis methods included (1) cluster analysis using the Agglomerative Hierarchical Clustering method with the Ward's method, and (2) quadratic discriminant analysis. The results of the clustering analysis showed that there were some clusters due to variation of biomass, water, soil and air conditions. The three clusters developed based on water and/or air variables provided high cophenetic correlation (0.80) with low within-cluster (14.5%) and high between-cluster variations (85.5%). Based on the multicollinearity analysis, average vector difference test, variance matrix variance test, unidimensional test of each variable and quadratic discriminant function, this study found that there were 3 key indicators determining variations of the quality of the reclamation plantations within the study sites, namely, biological indicator of biomass volume (Bio_B); soil indicator of P content in the soil (Tnh_P), saturation base of soil (Tnh_Kb), Manganese (Mn) content in the soil (Tnh_Mn), Sulfur content in the soil (Tnh_S), percentage of ash in the soil (Tnh_Ab), percentage of clay in the soil (Tnh_Li), and water indicator of chloride content in the surface water (Air_Cl). The examination on four classes of the reclamation quality showed that the classes were successfully classified having excellent cross-validation error matrix with overall accuracy more than 90%.
